What is the relationship between 4, 16, and squares?

Hey there!

Our goal is to create the slope intercept equation for line W, which requires two things that we need to find out: the slope and the y-intercept.

We see that Line W is parallel to line V. Therefore, they have the same slope. So, the slope of Line W is 10/7.

Now, we need to find the y-intercept. To do this, we will plug the slope and the point we are given into the slope intercept equation and solve for b.

-3= 10/7(-3)+b

-3= -4 2/7+b

b=1 2/7

Now, we plug this into our final slope intercept form.

y=10/7x+1 2/7

I hope this helps! Have a great day!

Answer:

Half of the 10-inch quesadilla is greater than the entire 5-inch quesadilla

Step-by-step explanation:

we know that

The area of a circle is equal to

[tex]A=\pi r^2[/tex]

where

r is the radius

step 1

Find the area of the 10 inch-round quesadilla

we have

[tex]D=10\ in[/tex]

[tex]r=10/2=5\ in[/tex]

substitute

[tex]A=\pi (5)^2[/tex]

[tex]A=25\pi\ in^2[/tex]

step 2

Find the area of the 5 inch-round quesadilla

we have

[tex]D=5\ in[/tex]

[tex]r=5/2=2.5\ in[/tex]

substitute

[tex]A=\pi (2.5)^2[/tex]

[tex]A=6.25\pi\ in^2[/tex]

step 3

Which is larger, half of the 10-inch quesadilla or the entire 5-inch quesadilla?

Compare

half of the 10-inch quesadilla is equal to ----> [tex]\frac{1}{2}(25\pi)=12.5\pi\ in^2[/tex]

the entire 5-inch quesadilla ---->[tex]6.25\pi\ in^2[/tex]

therefore

Half of the 10-inch quesadilla is greater than the entire 5-inch quesadilla

Answer:

Option A -280 feet

Step-by-step explanation:

Let

x ----> the lowest elevation in Long Beach, California in feet

y ----> the approximate elevation of Death Valley in feet

Remember that

An elevation below the sea level is negative and above the sea level is positive (The sea level is the level zero)

we know that

The lowest elevation in Long Beach, California, is 7 feet below sea level

so

[tex]x=-7\ ft[/tex]

The elevation  of Death Valley is about 40 times lower than the elevation of Long Beach.

so

[tex]y=40x[/tex]

substitute the value of x

[tex]y=40(-7)=-280\ ft[/tex]

therefore

The approximate elevation of Death Valley is about 280 feet below the sea level

Area of the figure is 42 in²

Step-by-step explanation:

⇒ Area of the rectangle = length × width = 6 × 5 = 30 in²

⇒ Area of the triangle = 1/2 × base × height = 1/2 × 4 × 6 = 12 in²

∴ Area of the figure = 30 + 12 = 42 in²

Step-by-step explanation:

Nicole starts with the budget:

$395

Now, she only expects to pay half the deposit;

$72 ÷ 2 = $36

Subtract this from the budget:

$395 - $36 = $359

Divide by cost per hour:

$359 ÷ $60 = 5.983333... (3 repeating)

This means, Nicole can rent a maximum of 5 hours with her budget. The inequality would be

[tex]x \leqslant 5[/tex]

Solution:

Given that,

Amanda answered all the questions on her math test but got 10 answers wrong

She received 4 points for every correct answer, and there were no points for wrong answers

Find the number of questions answered correctly:

Her final score was 76 points

4 points for every correct answer

Thus,

[tex]correct\ answers = \frac{76}{4} = 19[/tex]

From given.

Incorrect answers = 10

Let "x" be the total number of questions on his math test

Then,

x = correct answered questions + incorrect answered questions

x = 19 + 10

x = 29

Thus there are 29 total number of questions on his math test

Amanda's test had 29 questions in total.

Amanda answered all the questions on her math test but got 10 answers wrong. She received 4 points for every correct answer, with no points for wrong answers, and her final score was 76 points.

Step-by-Step Solution

1. Let q represent the total number of questions on the test.

2. The number of correct answers Amanda got is (q - 10).

3. Amanda's score for correct answers can be represented as 4 × (q - 10).

4. According to the problem, her score was 76 points, so we can set up the equation: 4 × (q - 10) = 76.

5. Simplify and solve for q:
4q - 40 = 76
4q = 116
q = 29

Therefore, the total number of questions on Amanda's math test is 29.

Final answer:

The ratio of the surface areas of the two cubes with a linear scale factor of 4:1 is 16:1, because surface area is proportional to the square of the scale factor.

Explanation:

When working with scale factors in geometry, and specifically with cubes, the ratio of scale factors for linear dimensions affects the surface area and volume in specific ways. If two cubes have a scale factor of 4:1, the ratio of their surface areas is the square of the scale factor. Since the scale factor for the linear dimensions is 4, the ratio of the surface areas will be 42:12, or 16:1.

The surface area of a cube is calculated by multiplying the area of one face (length x width) by 6, as a cube has 6 faces. If one cube has a side four times as long as the other, each of its faces will be 42 times larger because area is a two-dimensional measurement. Thus, the surface area of the larger cube will be 16 times greater than that of the smaller cube, hence the ratio 16:1.

Answer:

The expression showing how many more meters Mathieu ran than Edgar ran during that time is  [tex]t(m-e)[/tex].

Step-by-step explanation:

Edgar ran 'e' meters per second, and Mathieu ran 'm' meters per second. The boys ran for 't' seconds.

The expression [tex]t(m-e)[/tex] describes how many more meters Mathieu ran than Edgar ran during that time.

We can also use the expression [tex]tm-te[/tex] represent the same quantity.

We know that,

[tex]\text{Distance} =\text{Speed}\times \text{Time}[/tex]

Distance covered by Edgar = te

Distance covered by Mathieu = tm

Difference in distance [tex]d= tm - te=t(m-e)[/tex]

The expression showing how many more meters Mathieu ran than Edgar ran during that time is  [tex]t(m-e)[/tex].

Question 5

y = - 3x

Question 6

[tex]y = \frac{50}{x} \\ [/tex]

The surface area is the area of all the faces of the solid.

So, it is composed by the two triangles (front and rear) and the two lateral rectangles.

The triangles have base 12 and height 8 (both given), so their area is

[tex]A_t=\dfrac{12\cdot 8}{2}=12\cdot 4=48[/tex]

The rectangles have base 14 and height 10 (both given), so their area is

[tex]A_r=14\cdot 10=140[/tex]

Finally, there's a base rectangle with dimensions 14 and 12, which has area

[tex]A_b = 14\cdot 12 = 168[/tex]

The surface area is made of two lateral rectangles, one base rectangle and two triangles, so it is

[tex]S=2A_r+2A_t+A_b=96+280+168=544[/tex]

Final answer:

Provides equations to find the area and width of a rectangular deck based on given information.

Explanation:

a. Let the width of the deck be w. The length is given as 6 feet more than 2 times the width, which translates to 2w + 6. The area of a rectangle is length multiplied by width, so for this case, the equation expressing the area in terms of the width is w(2w + 6) = 80.

b. By solving the equation w(2w + 6) = 80, we find the width of the deck to be 10 feet.

x = 45°

Solution:

Given data:

Measure of larger arc = 152°

Measure of smaller arc = 62°

If a tangent and a secant intersect at the exterior of a circle then the measure of angle formed is one-half the positive difference of the measures of the intercepted arcs.

[tex]$\Rightarrow x = \frac{1}{2}(\text{ larger arc }- \text{smaller arc} )[/tex]

[tex]$\Rightarrow x = \frac{1}{2}(152^\circ-62^\circ)[/tex]

[tex]$\Rightarrow x = \frac{1}{2}(90^\circ)[/tex]

⇒ x = 45°

The value of x is 45°.

Answer:

1056.25 pi

Step-by-step explanation:

f the circumference of the circle is 65\pi, then the diameter is 65. If the diameter is 65, the radius is \frac{1}{2} * 65, and then you would do 32.5^2 * \pi, which would equal

Answer:

A =1056.25 pi

Step-by-step explanation:

The circumference is given by

C = 2*pi*r

65 pi = 2*pi*r

Divide each side by 2 pi

65 pi /2 pi = 2*pi*r/2pi

32.5 = r

To find the area

A = pi * r^2

A = pi *(32.5)^2

A =1056.25 pi

Step-by-step explanation:

just multiply everything

The probability of not drawing an I is the number of non-I letters divided by the total number of letters, which is 7/11.

The word MISSISSIPPI has a total of 11 letters, with the following distribution: 4 I's, 4 S's, 2 P's, and 1 M. To find the theoretical probability of NOT drawing an I, we need to consider all the other letters that could be drawn instead. There are 11 - 4 = 7 letters that are not Is. Therefore, the probability of not drawing an I is the number of non-I letters divided by the total number of letters, which is 7/11.

Answer:

y = 4/5 x - 2

Step-by-step explanation:

Slope:

y₂ - y₁ / x₂ - x₁

6 - 2 / 10 - 5

4 / 5

y = 4/5 x + b

Solve for b by substituting one of the point's coordinate to the equation:

I'll use (5,2)

y = 4/5 x + b

(2) = 4/5 (5) + b

2 = 4 + b

2 - 4 = b

-2 = b

y = 4/5 x - 2

Answer:

$6.03

Step-by-step explanation:

Let the amout Travis spent on pizza be reapresented as A.

Travis bought a sticker for $2.53,

Belt = $5.68

Pizza = ?

Total amount of money spent = $14.24

To get the amount spent on pizza , add up amount of everything he bought and equate them to total amount spent

That’s

$2.53 + $5.68 + A = $14.24

$8.21 + A = $14.24

Subtract $8.21 from both sides

$8.21 - $8.21 + A = $14.24 - $8.21

A = $6.03

Travis spent $6.03 on the pizza

Step-by-step explanation:

Let the required number be x.

Therefore, according to the given condition:

[tex] {x}^{2} - 10 = 3x \\ \therefore \: {x}^{2} - 3x - 10 = 0 \\ \therefore \: {x}^{2} - 5x + 2x - 10 = 0 \\ \therefore \: x(x - 5) + 2(x - 5) = 0 \\ \therefore \: (x - 5)(x + 2) = 0 \\ \therefore \: x - 5 = 0 \: \: or \: \: x + 2 = 0 \\ \therefore \: x = 5 \: \: or \: \: x = - 2 \\ [/tex]

Therefore, x = - 2 is the negative solution.

Good morning ☕️

Answer:

Step-by-step explanation:

First ,we need to model the situation by expressing it as an equation

so, let x represent the uncknown negative number :

We get

x² - 10 = 3x

then

x² - 3x - 10 = 0

now using the quadratic formula:

Let Δ be the discriminant

Δ = b² - 4ac = (-3)² - 4(1)(-10) = 9 + 40 = 49 → √∆ = 7

Therefore

[tex]x = \frac{3+7}{2}=5 \\or\\x= \frac{3-7}{2}=-2[/tex]
