A solution to 8 = -x + 10 is 2

Answer:

x = 39

Step-by-step explanation:

In the image, in order for DE to be parallel to CB, the scale factor between AE and EB should be the same as between AD and DC. To solve this, you first need to identify these lines:

AE = 12, EB = x - 3

AD = 6, DC = 18

Now, you need to find the scale factor by dividing 18 by 6:

18 ÷ 6 = 3

So the scale factor from AD to DC is 3. This means that the scale factor from AE (12) to EB should also be 3. You can find x by writing and solving an equation:

12 × 3 = x - 3 (given)

36 = x - 3 (simplify)

x = 39 (add 3 to both sides)

So x = 39.

The correct answer to the question is option d) 75 PCF.

To calculate the expected vertical load, we need to consider the weight of the concrete slab and the additional load due to the concrete's temperature and pouring rate. The weight of the slab can be calculated by multiplying the density of the concrete (150 PCF) by the depth (6 inches) and the area (1 square foot). This gives us a weight of 75 pounds per square foot (PSF).

The temperature and pouring rate do not directly affect the vertical load. The temperature and pouring rate are factors that may affect the structural integrity of the slab or the time it takes for the concrete to fully cure. However, they do not contribute to the actual load borne by the slab itself. Therefore, the correct answer is 75 PCF, as it represents the weight of the concrete slab alone.

Answer:

1/2 < 3/5 < 2/3 < 5/6

Step-by-step explanation:

Using the given inputs:

1/2 5/6 2/3 3/5

The least common denominator (LCD) is: 30.

Rewriting as equivalent fractions with the LCD:

1/2 5/6 2/3 3/5

15/30 25/30 20/30 18/30

Sorting this table by the numerators of the equivalent fractions in order from least to greatest:

1/2 3/5 2/3 5/6

15/30 < 18/30 < 20/30 < 25/30

Therefore, the sorted inputs in order from least to greatest is:

1/2 < 3/5 < 2/3 < 5/6

Answer:

C.

Step-by-step explanation:

x is bisecting the baseline (cutting it in 2 halves of 6).

the third angle in the main overall triangle is 60 degrees.

remember, all angles in a triangle always add up to 180 degrees.

so, 180 - 60 - 60 = 60.

that means that all 3 angles are of equal size (60). and that means that all 3 sides must have the same length.

=> y = 12

and now using Pythagoras to calculate the height (x) of the triangle :

y² = x² + 6² (remember, this side is only half the baseline)

12² = x² + 6²

144 = x² + 36

x² = 108

x = sqrt(108) = sqrt(36×3) = 6×sqrt(3)

Proving by Vertex Form:Yes, if we put this equation in vertex form

\(a(x - h) {}^{2} + k\)

where h,k is vertex

we can find if it reaches 5.

First we do -b/2a.

\( \frac{ - 1}{10} \)

Is a solution, if we plug that in we get

Which gives

\(3.95\)

So the vertex form is

\(5(x + 0.1) {}^{2} + 3.95\)

Since the graph is facing upwards,because a is positive, the function will pass all values greater than 3.95, and 5 is one of them

Second Way: Watch if you want to see how long is reaches 5 meters.

Set the quadratic equation equal to 5.

\(5 {t}^{2} + t + 4 = 5\)

\( {5t}^{2} + t - 1 = 0\)

\(5 {t}^{2} + t - 1 = 0\)

Do quadratic formula, which is

\( - b± \frac{ \sqrt{b {}^{2} - 4ac} }{2a} \)

So a is 5 b is 1 and c is -1 so we get

\( - 1± \frac{ \sqrt{1 {}^{2} - 4( 5)( - 1)} }{2(5)} \)

\( - 1± \frac{ \sqrt{1 + 20} }{10} \)

\( - 1± \frac{ \sqrt{21} }{10} \)

\( \frac{ - 1}{10} + \frac{ \sqrt{21} }{10} \)

and

\( \frac{ - 1}{10} - \frac{ \sqrt{21} }{10} \)

are the solutions but since time is scalar, it can't be negative so qe take the positive solution

\( \frac{ - 1}{10} + \frac{ \sqrt{21} }{10} \)

which is approximate 0.358.

So if you wanted to know, it will take 0.36 seconds to reach a height of 5 meters.

The  true statement about the quasi-experiment is , the researcher assigns participants to conditions based on the participant's preexisting level of the independent variable.

In a quasi-experiment, the researcher assigns participants to conditions based on the participant's preexisting level of the independent variable. However, unlike a true experiment, a quasi-experiment cannot control for all possible confounding variables and may not allow for the balancing of participant variables between groups. Therefore, while a quasi-experiment can provide some evidence of causality, it may not be as accurate as a true experiment in this regard.

In a quasi-experiment, the researcher assigns participants to conditions based on the participant’s preexisting level of the independent variable.

A quasi-experiment is a research design that lacks the control of random assignment to groups. Instead, the researcher assigns participants to conditions based on pre-existing levels of the independent variable. This means that the groups may not be equivalent at the outset, and there is a greater risk of confounding variables affecting the results.

Therefore, we cannot balance participant variables between groups in a quasi-experiment, nor can we randomly assign participants to groups. While quasi-experiments can provide valuable information, they do not allow us to infer causality more accurately than other research designs.

Yan po answer

Answer: 5 years

Step-by-step explanation:

Given

Linda is \(3\ \frac{1}{3}\ yr\) younger than Rose

Johan is \(8\ \frac{1}{3}\ yr\) older than Linda

Suppose the age of Rose is \(x\)

So, Linda's age

\(x-\dfrac{3\times3+1}{3}=x-\dfrac{10}{3}\)

Johan's age

\(x-\dfrac{10}{3}+\dfrac{8\times3+1}{3}=x+\dfrac{-10+25}{3}\\\\x+\dfrac{15}{3}=x+5\)

Difference between the Rose's and Johan's age is

\(\Rightarrow x+5-x=5\ yr\)

The Riemann sum that represents the illustration on the graph is the second option as i goes from 1 to 4:

\(1∑2 {(xᵢ)}^{2} \)

The Riemann sum is a mathematical concept used to approximate the area under a curve. It is named after the German mathematician Bernhard Riemann.

The idea behind the Riemann sum is to divide the area under the curve into a series of rectangles, where the height of each rectangle is determined by the function being integrated, and the width of each rectangle is determined by the size of the intervals used to divide the domain of the function. The area of each rectangle is then calculated and added together to get an approximation of the total area under the curve.

The Riemann sum is written in the following form:

\(∑f(xᵢ)Δxᵢ\)

where f(xᵢ) is the value of the function at the ith point in the interval, Δxᵢ is the width of the ith rectangle, and the sum is taken over all i intervals.

Thus, the Riemann sum that represents the illustration on the graph as i goes from 1 to 4 is:

\(1∑2 {(xᵢ)}^{2} \)

Shortest distance from the point (2, 0, -3) to the plane x + y + z = 1 is √3 units.

To find the shortest distance between a point and a plane, we can use the formula:

distance = |ax + by + cz + d| / √(a² + b² + c²)

where a, b, and c are the coefficients of the plane's equation, d is the constant term, and (x, y, z) is the coordinates of the point.

In this case, the plane is x + y + z = 1, so a = 1, b = 1, c = 1, and d = -1. The point is (2, 0, -3), so x = 2, y = 0, and z = -3. Plugging in these values, we get:

distance = |1(2) + 1(0) + 1(-3) - 1| / √(1² + 1² + 1²)

= 3 / √3

= √3

Therefore, the shortest distance from the point (2, 0, -3) to the plane x + y + z = 1 is √3 units.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

We will solve for x.

a) 4x - 3 = 2x + 7

4x - 3 = 2x + 7

Subtract 2x on both sides.

4x - 2x - 3 = 7

2x - 3 = 7

Add 3 on both sides.

2x = 7 + 3

2x = 10

Divide both sides by 2.

x = 5

b) 2x + 6 = 7x - 14

Subtract 2x on both sides.

6 = 7x - 2x - 14

6 = 5x - 14

Add 14 on both sides.

6 + 14 = 7x

7x = 20

Divide both sides by 7.

x = 20/7

I learned this in Macro Chapter 34.

Total Seeds required 9.33 kg  and she has 10 kg.so, she has enough grass seed to make a lawn 10m by 14 m.

If you're fortunate enough to have a rectangular lawn, determining the size is straightforward. Multiply the length and breadth measurements together to get the total. You now have your region/area.

So, Maisie knows that she needs 3 kg of grass seed to make a rectangular lawn 5 m by 9m.

Grass seed is sold in 2 kg boxes,

Maisie wants to make a rectangular lawn 10 m by 14 m,

She has 5 boxes of grass seed

To Find, Has Maisie got enough grass seed to make a lawn 10m by 14 m

Solution:

3 kg of grass seed to make a rectangular lawn 5 m by 9m.

=> 3 kg  of grass seed  needed for 5 x 9 = 45 m²

=>  1 m² required  = 3/45  kg seed

a rectangular lawn 10 m by 14 m,

area = 10 x 14 = 140 m²

Hence 140 m² required = 140 x  3/45  =  9.33 kg

Grass seed is sold in 2 kg boxes,

She has 5 boxes of grass seed

Hence total seeds = 5 x 2 = 10 kg

Therefore, total seeds required 9.33 kg  and she has 10 kg.so, she has enough grass seed to make a lawn 10m by 14 m.
