Answer:

E) 4.47

Step-by-step explanation:

3x²+31=91

3x²=91-31

3x²=60

x²=60÷3

x²=20

x=√20

x=4.47

Answer:

4.47

Step-by-step explanation:

the only rational answer for this is 4.47 because once you solve as much as you can, you should end up with a whole number multiplied by a square root. the decimal form of that  number is 4.47

Answer:

y= 4x+3

Step-by-step explanation:

Slope intercept is y=mx+b, with m being slope and b being the y intercept. 4 is the slope, 3 is the y intercept

This is simply what I wrote for my assignment, sorry I am a bit late.

It was confusing when she took out the negative and postive pairs, but then I soon knew that the negative tiles are like subtracting positive tiles. Then once she got the total I was amazed with how easy it was to find out the value of x.

hope this helps! <3

Step-by-step explanation:

step 1. The easiest way is to use Herons formula.

step 2. s = (a + b + c)/2 = (3 + 5 + 6)/2 = 7

step 3. A = sqrt(7(7-4)(7-5)(7-6))

step 4. A = sqrt(7(3)(2)(1))

step 5. A = sqrt(42)

step 6. A = 6.4807 = 6.5cm^2.

5 times 9 is 45. 45/6 simplified is 7 3/6 or 7 1/2

Answer:

The p-value is greater than α , and the null hypothesis is not rejected. There is not convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.

Step-by-step explanation:

The claim is not supported. Since 0.37>0.10, the null hypothesis is not rejected. There is not convincing statistical evidence that the proportion of times she needs to stop at the crossing is different for the different routes.

Answer: Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m.

Step-by-step explanation:

Answer:

slope = [tex]\frac{7}{4}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (3, 4) ← 2 points on the line

m = [tex]\frac{4-(-3)}{3-(-1)}[/tex] = [tex]\frac{4+3}{3+1}[/tex] = [tex]\frac{7}{4}[/tex]

Answer:

The pizza is 8.99 per pizza.

Step-by-step explanation:

Answer:

84

Step-by-step explanation:

[tex]7 + (15 - 5) \times (10 - 6) \times \frac{1}{2} + 5 \times 10 = 84[/tex]

Answer:

The answer is 84 inches Squared!

Step-by-step explanation:

Here is the explanation to the answer:-

All you have to do is divide the whole figure into some parts!

Here is what I have divided the figure into.

The triangle area is 1/2 * L*H

The measurements are 1/2 * 4*3 = 6in Squared.

                         ( The Next Shape To The Triangle)

 Rectangle area is L*B

The Measurements are 4*7 = 28inches Squared.

                          (The next shape to the rectangle)

Rectangle area is L*B

Measurements are 5*4 = 20inches squared.  

                                    (Above Shape of the rectangle)

Area of rectangle is L*B

Measurements are 6*5 = 30 Inches Squared.

    Now, add all the areas of the figure:-

6 + 28 + 20 + 30 = 84 Inches Squared.

Thanks, and hope this helps.

Based on the question, each person will have 2/3 of the item

From the given information, we are told that 2 items are being divided equally among 3 people. This can be expressed as:

For each person;

x = 1 person

Take the ratio to have:

2/x = 3/1

3x = 2

x = 2/3

This shows that each person will have 2/3 of the item

Step-by-step explanation:

one meter is 100 centimeters

Answer:

x + 12 ft

Step-by-step explanation:

Area = base times height.  Here we know the area (x^2 + 9x - 36) and the width (x - 3).  Since area = length times width, divide the given area by x - 3.

x^2 + 9x - 36 factors into (x - 3)(x + 12).

Dividing this result by x - 3 yields the length:  x + 12 ft

Answer:

Step-by-step explanation:

Answer:

x = 36/5, x = 7 1/5, x = 7.2

Step-by-step explanation:

4/x = 5/9

36 = 5x

5x = 36

divide both sides by 5

x = 36/5.

Answer:

1.5q - 5r = 2

Step-by-step explanation:

All you need to do here is negate each term inside the brackets, which allows you to get rid of the minus sign and the brackets.

-(-1.5q + 5r) = 2

is exactly the same as saying:

-1 × (-1.5q + 5r) = 2

And if we multiply each term in the brackets by negative one, we get:

(1.5q - 5r) = 2

And now the brackets can go, leaving you with:

1.5q - 5r = 2
