Answer:

$761.25, A on edg

Step-by-step explanation:

The bank balance of omar from the given account is; $761.25

To get his account balance after the credit and debit, we need to add all the amount debited and deduct from all the amount credited.

Total amount debited = 425 + 22.3 + 26.75

Total amount debited = $474.05

The total amount credited + balance = $1015.50 + $219.8 = $1235.3

Thus;

Omar's bank balance = $1235.3 - $474.05

Omar's bank balance = $761.25

sorry for my speling erros

She rode a total distance of 16 miles this week.

An expression in mathematics is a combination of terms both constant and variable. For example, we can write the expressions as -

2x + 3y + 5

2z + y

x + 3y

The distance rode by Lexi per day is mentioned below -

Monday - Lexi rode 3 miles on a bike.

Tuesday - Lexi rode 3 times more than she did Monday.

Wednesday - Lexi rode an additional 4 miles.

We can write the expression to find the total distance in miles covered by Lexi as -

d = d{M} + d{T} + d{W}

d = 3 + (3 + 3) + 4

d = 3 + 6 + 4

d = 13 miles

Therefore, she rode a total distance of 16 miles this week.

There are 43 small dogs signed up in the competition

Represent the small dogs with x and the large dogs with y.

So, we have the following equations

x + y = 50

x = 36 + y

Make y the subject in x = 36 + y

y = x - 36

Substitute y = x - 36 in x + y = 50

x + x - 36 = 50

Evaluate the like terms

2x = 86

Divide both sides by 2

x = 43

Hence, there are 43 small dogs in the competition

Answer:

C

Step-by-step explanation:

A list of 6 one digit whole numbers with an average of 5, a median of 6, a range of 9, and no mode is

since the numbers will have no mode so they are all different

Assuming the numbers are: a, b. c. d. e. and f

The average is 5

(a + b + c + d + e + f ) / 6 = 5

a + b + c + d + e + f = 30

The median is 6

(c + d)/2 = 6

c + d = 12  (assume c = 5 and d = 7)

range is 9

f - a = 9, since it is a one digit number a range of 9 is possible for 9 - 0

hence a = 0 and f = 9

substituting assumed values to the average

0 + b + 5 + 7 + e + 9 = 30

b + e + 21 = 30

b + e = 9 (let b = 8and e = 1)

hence the numbers are

0, 1, 5, 7, 8, and 9

In mathematics →

Given is that compared to last month, there was a 50% increase in the number of houses sold this month.

Assume that the number of houses sold of previous moth were [x]. Then, we can write -

y = {x} + 50% of {x}

y = {x} + (50/100) × {x}

y = {x} + {x/2}

y = 3x/2

Given:A circle is centered at point B. Points A, C, and D lie on its circumference. ADC measures 62 degrees. To Find: What does ABC measure?Solution:We know that a circle is of 360 degrees.

Therefore, the measure of the angle ABC can be found as follows: Firstly, we can find the measure of angle ABD using the fact that angle ADC is 62 degrees.ABD is an inscribed angle which has the arc ADC as its intercept.

The measure of angle ABD is half the measure of arc ADC. So, angle ABD measures (62)/2 = 31 degrees.

Now, angle ABC is an inscribed angle which has the arc ADC as its intercept as shown in the figure attached below:Since arc ADC intercepts angles ABD and ABC, so the sum of angle ABD and angle ABC is equal to the measure of arc ADC.

Hence, angle ABC = Measure of arc ADC - Measure of angle ABD= 62 degrees - 31 degrees= 31 degreesTherefore, ABC measures 31 degrees.

The expression cosθ(1 + tan²θ) will be equal to secθ, so the given expression is correct.

We can prove the expression true by making Left-hand side equal to the Right-hand side. On the left hand side we have the expression

cosθ(1 + tan²θ)

We know, tanθ = sinθ/cosθ, by using this in above expression we get

cosθ(1 + (sin²θ/cos²θ))

On further simplifying we get

cosθ(cos²θ + sin²θ/cos²θ)

Now from trigonometric identity; cos²θ + sin²θ = 1 the expression becomes

cosθ(1/cos²θ)

= 1/cosθ

= secθ which is equal to the right hand side vale. So it is proved.

Jim can paint 1/2 of a house in one hour, which means he can paint 1/12 of a house in 10 minutes. Jane can paint a whole house in 1/5 hour, which means she can paint 1/5 of a house in 1 minute.

When Jane joins Jim after 10 minutes, Jim has already painted 1/12 of a house. Together, they paint 1/12 + 1/5 of a house in one minute.

To find out how long it will take them to paint one whole house together, we can set up the equation:

1/12 + 1/5 = x/1

Where x is the amount of time it takes them to paint one whole house together.

Combining the fractions on the left side, we get:

(5 + 12)/60 = x

Simplifying, we get:

17/60 = x

Therefore, it will take Jim and Jane 17/60 of an hour, or approximately 17 minutes and 0.3 seconds, to complete one whole house together.\

Answer:

D. 36

Step-by-step explanation:

Ratios are a way to represent of how much there is one thing to another. It's a more simplistic representation.

For example, if there were 625 adults and 375 children, we don't say there are 625 adults to 375 children, we say there are 5 adults to 3 children.

All I did was divide both the number of children and adults by 125 and we have a ratio of 5:3 for adults to children respectively.

In this problem, we have a ratio of 3:2 for girls to boys. This 3:2 ratio is a simplistic representation of the number of girls to boys. We know that there are 24 boys.

Dividing 24/2 = 12

12 is the proportion which we multiply by the ratio to get the true numbers for boys and girls.

2 * 12 = 24 boys

3 * 12 = 36 girls

So there are 36 girls in the marching band.

Yonna, this is the solution to the problem:

Side 1 of the tablet = (4x + 3) cm

Side 2 of the tablet = (-4x² - 2x - 3) cm

Area of the tablet = Side 1 * Side 2

Area of the tablet = (4x + 3) * (-4x² - 2x - 3) cm²

Area of the tablet = (4x * -4x²) + (4x * -2x) + (4x * -3) + (3 * -4x²) + (3 * -2x) + (3 * -3)

Area of the tablet = -16x³ - 8x² - 12x - 12x² - 6x - 9 cm²

Area of the tablet = -16x³ - 20x² - 18x - 9 cm²

A carboxylic acid derivative is a functional group that contains a carbonyl group adjacent to an ether or an acyl group, including acid chlorides, anhydrides, esters, and amides. The most common type of carboxylic acid derivative is an ester.

The condensation of a carboxylic acid with an alcohol to form an ester is a common synthetic route for esters. Let's go through the multistep synthesis of a carboxylic acid derivative.Step 1: Synthesis of methyl 2-bromo-2-methylpropanoate.

Starting material: Methanol, acetic anhydride, and concentrated sulfuric acid. Procedure: A reaction between methanol and acetic anhydride catalyzed by sulfuric acid produces methyl acetate. Afterward, methyl acetate reacts with 2-bromo-2-methylpropanoic acid in the presence of sodium carbonate to produce methyl 2-bromo-2-methylpropanoate. Methyl acetate + 2-bromo-2-methylpropanoic acid + sodium carbonate ⟶ Methyl 2-bromo-2-methylpropanoateStep 2: Synthesis of 2-bromo-2-methylpropanoic acid.

Starting material: 2-methylpropene and bromine. Procedure: 2-methylpropene reacts with bromine to create 2-bromo-2-methylpropane. Furthermore, hydrolysis of 2-bromo-2-methylpropane in the presence of sodium hydroxide results in 2-bromo-2-methylpropanoic acid. 2-methylpropene + Bromine ⟶ 2-bromo-2-methylpropane2-bromo-2-methylpropane + sodium hydroxide ⟶ 2-bromo-2-methylpropanoic acidStep 3: Synthesis of 3-bromo-2-methylpropanoic acid. Starting material: Methyl 2-bromo-2-methylpropanoate.

Procedure: The hydrolysis of Methyl 2-bromo-2-methylpropanoate in the presence of sodium hydroxide results in 3-bromo-2-methylpropanoic acid. Methyl 2-bromo-2-methylpropanoate + sodium hydroxide ⟶ 3-bromo-2-methylpropanoic acidThus, this is the synthesis of a carboxylic acid derivative by following a multistep reaction mechanism with a total of three steps.

Answer:

y = 2x + 7

Step-by-step explanation:

y = mx + b  The point (-2,3) gives us an x value and a y value that we can use.  We are also give the slope (m).  All we need to do is figure out the b (y-intercept) value.

y = mx + b

3 = 2(-2) + b

3 = -4 + b  Add for to both sides

7 = b  We know have every thing that we need to write the equation.  We have the slope (m) which is 2 and the b (y-intercept) that we just figured out is 7

y = 2x + 7

Answer is y= 2x +7

Step by step.

Using y intercept form, find y intercept by substituting the known points and slope into the equation and solve for b.

y = mx + b.

3 = (2) (-2) + b

3 = -4 + b

Now solve for b by adding 4 to both sides.

7 = b

Now we have y = 2x +7 as our equation.

Simple polygons with three sides and three internal angles make up triangles.

It is one of the fundamental geometric shapes in which the three vertices are connected to one another.

Triangles come in 4 different varieties.

1. Equilateral: Equilateral triangles have three equal sides and three identical 60-degree angles.

2. Isosceles: Isosceles triangles have equal sides and angles on both of their two sides.

3. Right-angled: In right-angled triangles, one of the angles is a right angle (90°).
