Sara's score is 10.5; Hamza's score is 2.5; Luna's score is 8. The inequality for Mario's score is M ≥ 23 - X - Y - K - Z.

c) Let H be Hamza's score. Then we have the equation H + 4.5 = 7. Solving for H, we get:

H = 7 - 4.5 = 2.5

Therefore, Hamza's score is 2.5.

d) Let L be Luna's score. Then we have the equation L - 4 = 4. Solving for L, we get:

L = 4 + 4 = 8

Therefore, Luna's score is 8.

e) Let M be Mario's score. Then we have the inequality:

X + Y + K + Z + M ≥ 23

We can rearrange this inequality as:

M ≥ 23 - X - Y - K - Z

This represents the minimum score that Mario needs to achieve in order for the sum of all scores to be at least 23. Since we don't know the values of X, Y, K, and Z, we can't determine a specific value for M.

However, we can graph this inequality on a coordinate plane to see the possible values of M that satisfy the inequality.

The measure of angle B is approximately equal to 56.31 degrees, rounded to two decimal places.

An angle measure is a numerical value that represents the amount of rotation between two intersecting lines, line segments or rays. It is typically measured in degrees, although other units of measurement such as radians and grads may also be used. The size of an angle can range from 0 degrees (corresponding to no rotation or a straight line) to 360 degrees (corresponding to a full rotation). In geometry, angles are used to describe the relationships between lines and shapes, and are an important concept in fields such as trigonometry and calculus.

To find the measure of angle B given cot B = 0.57736, we can use the inverse tangent function.

The tangent of an angle is the ratio of the opposite side to the adjacent side,

So cot B = adjacent side / opposite side.

By taking the inverse tangent of both sides and substituting cot B for adjacent side / opposite side, we arrive at the equation

B = arctan(cot B).

Evaluating arctan(cot B) using a calculator gives us the measure of angle B as,

B = arctan(cot B) = 56.31° (rounded to two decimal places)

Answer:

2/4

Step-by-step explanation:

Answer:

BC = 3

AC = 6

DE = 4

Explanation:

Given that B is the midpoint of AC, this means that AB and BC are equal.

Since AB = 3, BC = 3

AC = AB + BC

= 3 + 3

AC = 6

AC is equivalent to CE

Since AC = 6

CE = 6

But CE = CD + DE

Given CD = 2

CE = 2 + DE

6 = 2 + DE

Subtract 2 from both sides

6 - 2 = 2 + DE - 2

DE = 4

Step-by-step explanation:

The computation of allocating the joint cost using the physical units method is shown below:

\(Allocation\ rate = \frac{Joint\ costs}{Total\ number\ of\ products}\)

\(= \frac{\$200,000}{300 + 200 + 300}\)

\(Allocation\ rate = \frac{200,000}{800}\)

= 250

For face cream

\(= Unit\ produced\times Allocation\ rate\)

= \(300\times 250\)

= 75,000

For body lotion

\(= Unit\ produced\times Allocation\ rate\\\\ = 200\times 250\)

= 50,000

For Liquid soap

\(= Unit\ produced\times Allocation\ rate\\\\ = 300\times 250\)

= 75,000

hence, we simply applied the above formula by multiplying the units produced with the allocation rate so that each one allocation cost could come

The unit rate of computers per day using the graph is that 12 computers are made per day.

The unit rate is how many units of quantity correspond to the single unit of another quantity. We say that when the denominator in rate is 1, it is called unit rate. Unit rates is said to be the amount of something in each unit or per unit.

To obtain the unit rate of computers sold per day using the graph, we need to obtain the slope of the graph, which is the change in y per change in x

So, it is given by:

\(\text{Slope} = \dfrac{\text{change in y}}{\text{change in x}}\)

\(\text{Slope} = \dfrac{\text{y}_2-\text{y}_1}{\text{x}_2-\text{x}_1}\)

\(\text{y}_2 = 60 , \ \text{y}_1 = 36 , \ \text{x}_2 = 5, \ \text{x}_1 = 3.\)

\(\text{Slope} = \dfrac{(60 - 36)}{(5 - 3)} = \dfrac{24}{2} = 12\)

\(\bold{Slope = 12}\)

Unit rate = 12 computers per day.

Answer:

15/22.

Step-by-step explanation:

Let the denominator of original number be x.

Then the fraction is written as  x/(x+7).

From the given info:-

(x+17)/ (x + 7 - 6) = 2

(x+17)/(x+1) = 2

2(x+1) = x+ 17

2x + 2 = x + 17

x = 17-2 = 15.

So the original number = x/x+7

Answer:

Answer:

Step-by-step explanation:

Let the 100-digit number be represented as

$a_1a_2a_3\ldots a_{99}a_{100}$

We need to prove that there exist 88 digits that we can delete from this number such that the remaining number is divisible by 101.

We can represent the given number as a sum of powers of 10 as follows:

$a_1 \times 10^{99} + a_2 \times 10^{98} + a_3 \times 10^{97} + \cdots + a_{99} \times 10^1 + a_{100} \times 10^0$

We can use the fact that $10 \equiv -1 \pmod{101}$ to simplify the above expression as follows:

$a_1 \times (-1)^{99} + a_2 \times (-1)^{98} + a_3 \times (-1)^{97} + \cdots + a_{99} \times (-1)^1 + a_{100} \times (-1)^0$

which is equivalent to:

$-a_1 + a_2 - a_3 + \cdots + (-1)^{99} a_{99} + (-1)^{100} a_{100}$

We can group the terms as follows:

$(-a_1 + a_2 - a_3 + \cdots + a_{98} - a_{99}) + (a_{99} - a_{100})$

Notice that the first group of terms is the sum of 49 pairs of terms, each pair having a difference of $-1$ or $1$. Therefore, the sum of the first group of terms is either $-49$ or $49$.

Since none of the digits are 0, we know that $a_{99} \neq 0$ and $a_{100} \neq 0$, which implies that $a_{99} - a_{100}$ is not divisible by 101. Therefore, either $a_{99} - a_{100} = 1$ or $a_{99} - a_{100} = -1$.

Now consider the two cases:

Case 1: The sum of the first group of terms is $49$

In this case, we can delete the digits corresponding to the terms in the first group that have a negative sign. This will remove 49 digits, leaving us with a number that is equal to $(a_{99} - a_{100}) \times 10^1 = \pm 10$, which is divisible by 101.

Case 2: The sum of the first group of terms is $-49$

In this case, we can delete the digits corresponding to the terms in the first group that have a positive sign. This will remove 49 digits, leaving us with a number that is equal to $(-a_{99} + a_{100}) \times 10^1 = \pm 10$, which is divisible by 101.

Therefore, in either case, we can always delete 88 digits from the original number to obtain a number that is divisible by 101.

Answer:

m = \(\frac{3}{2}\)

Step-by-step explanation:

calculate the slope m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (- 3, - 1 ) and (x₂, y₂ ) = (3, 8 )

m = \(\frac{8-(-1)}{3-(-3)}\) = \(\frac{8+1}{3+3}\) = \(\frac{9}{6}\) = \(\frac{3}{2}\)

Answer:

3/2

Step-by-step explanation:

To find the slope, we use the slope formula

m = ( y2-y1)/(x2-x1)

    = (8- -1)/( 3 - -3)

    = (8+1)/(3+3)

     = 9/6

    = 3/2

Answer: 4 pounds is equal to 16 four-ounce (1/4 pound) increments.

To find the number of 3/4 pound bags Ann needs to buy, we can convert 16 four-ounce increments to three-fourth pound increments:

16 four-ounce increments = 16 x 4 = 64 ounces

64 ounces = 64/16 = 40 three-fourth pound increments

Therefore, Ann will need to buy 40 bags of walnuts, each weighing 3/4 of a pound.

If ABCD is dilated by a scale factor of 3, the coordinate of B' would be (-6, 6).

In Geometry, dilation simply refers to a type of transformation which typically changes the size of a geometric object, but not its shape.

This ultimately implies that, the size of the geometric shape would be increased (stretched or enlarged) or decreased (compressed or reduced) based on the scale factor applied.

Next, we would apply a dilation to the coordinates of the pre-image by using a scale factor of 3 centered at the origin as follows:

Ordered pair B (-2, 2) → Ordered pair B' (-2 × 3, 2 × 3) = Ordered pair B' (-6, 6).

To graph this equation, start at the origin (0,0) since there is not y-intercept.

Because slope is characterized by rise/run ( i.e. how many units up or down depending on whether it is positive or negative and then however many units to the right.

Because the rise (up and down, numerator) is 1, we know that we will go up one unit.

The run (side to side, denominator) is 4, so we will go to the right 4 units.

Complete question :

shopkeeper sells one machine for 990 re at a profit of 10% and another machine for 1960 at a loss of 2%. What is his gain or loss percent

Answer:

1.72%

Step-by-step explanation:

Given that :

MACHINE 1:

Sales price = 990

Profit percent = 10%

The cost price of the machine (x) :

10% profit of x :

(100 + 10)% of x = 990

110% of x = 990

1.1x = 990

x = 990/1.1

x = 900

MACHINE 2:

Sales price = 1960

Loss on sale = 2%

Cost price (x) :

(100 - 2)% of x = 1960

98% x = 1960

0.98x = 1960

x = 1960/0.98

x = 2000

Total amount realized from sale = (990 + 1960) = 2950

Total cost of production = (2000 + 900) = 2900

Profit Made = (2950 - 2900) = 50

% profit:

(Profit / cost of production) * 100

(50 / 2900) * 100%

0.0172413 * 100%

profit % = 1.72

The profit made is 50

Cost price of first machine will be:

= 100/(100 + 10) × 990

= 100/110 × 990

= 100 × 9

= 900

Cost price for second machine will be:

= (100 - 2) × x = 1960

= 98% × x = 1960

= 0.98x = 1960

x = 1960/0.98.

x = 2000

The total cost price = 900 + 2000 = 2900

Total selling price = 990 + 1960 = 2950

Therefore, profit will be:

= Selling price - Cost price .

= 2950 - 2900

= 50
