Since you know the value of x, you can substitute/plug it into the equation to find the value of y:

y = 2x + 5      Plug in 1 into "x" since x = 1

y = 2(1) + 5

y = 7

When x = 1, y = 7 -->  (x, y) = (1, 7)       Your answer is #4

Answer:

its $6

Step-by-step explanation:

the nearest tenth it 40, and the you ask google what 15% of 40 is.

Answer:

-80

Step-by-step explanation:

We have: -6 = [tex]\frac{x}{8}[/tex] + 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.

The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.

Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:

-6 - 4 = [tex]\frac{x}{8}[/tex] + 4 - 4  ⇒  -10 = [tex]\frac{x}{8}[/tex]

Then, multiply by 8 on both sides:

-10 * 8 = [tex]\frac{x}{8}[/tex] * 8  ⇒  x = -80

Thus, x = -80.

Hope this helps!

Answer:

x = -80

Step-by-step explanation:

Alright let's get started!

Rewrite the equation as ,

x/8 + 4 = -6

Move all terms not containing x to the right side of the equation.

(Subtract 4 from both sides of the equation.)

x/8 = -10

Multiply both sides of the equation by 8 to get rid of the denominator,

8 * x/8 = -10 * 8

8 cancels out on the left side,

x = -80

Answer: C

Step-by-step explanation:

The arc length, s, equals the radius, r, times the central angle, θ, given in radians. (In shorthand, s=r⋅θ.) If r=5 cm and θ=6 radians, the arc length is 5 cm⋅6=30 cm. If r=7 cm and θ=5 radians, the arc length is 7 cm⋅5=35 cm. If r=9 cm and θ=4 radians, the arc length is 9 cm⋅4=36 cm. An angle of 180∘ is π radians, or about 3.14. If r=10 cm, the arc length is 10 cm⋅3.14=31.4 cm. Of these choices, the longest arc is 36 cm.

Answer:

$62.50

Step-by-step explanation:

The original price is x

It is marked up 40 percent

x+.40x = new price

1.40x = new price

The new price is 87.50

1.40x = 87.50

Divide each side by 1.40

1.40x/1.40 = 87.50/1.40

x =62.50

The price before mark up is 62.50

Answer:

$62.50

Step-by-step explanation:

After mark up, price is

100 + 40 = 140% of cost

140/100 × Cost = 87.50

Cost = 87.50 × 100/140

Cost = $62.50

Answer:

5 =  (x - 2)^2

Step-by-step explanation:

sqrt(5) = x - 2

Square each side

(sqrt(5))^2 = (x - 2)^2

5 =  (x - 2)^2

Okay this is easier than you think!

if (x - 2) equals [tex]\sqrt{5}[/tex]

then that means  [tex](x-2)^{2}[/tex] = [tex]\sqrt{5} ^ {2}[/tex]

Anything under a square root when sqared, is itself

[tex]\sqrt{5} ^{2} = 5[/tex]

so the value of [tex](x-2)^{2}[/tex] = 5

Answer:

TS = 11.

Step-by-step explanation:

Consider triangles UTO and UCS.

m < C = m < UTO (Given)

< U is common to both triangles.

Therefore triangles UTO and OCS are similar.

So  corresponding sides are in the same ratio and:

5 / (TS + 4) = 4/ (7+5)

5 * (7 + 5) = 4(TS + 4)

TS + 4 =   5*12 / 4

TS + 4 = 15

TS = 11.

Answer:

Cholula

Step-by-step explanation:

first find the vlumes of the different pyramids:

FORMULA:

volume = (1/3) * basearea

Cholula- 157,583,664

Cheops- 91,204,000

Answer:

The Cholula Pyramid has a greater volume.

Step-by-step explanation:

volume = (1/3) * area of base * height

In both cases, the base is a square, so the area of the base is (side)^2

volume = (1/3) * (side)^2 * height

Cholula Pyramid:

volume = (1/3) * (side)^2 * height

volume = (1/3) * (1476 ft)^2 * 217 ft

volume = 157,583,664 ft^3

Cheops Pyramid:

volume = (1/3) * (side)^2 * height

volume = (1/3) * (755 ft)^2 * 480 ft

volume = 91,204,000 ft^3

The Cholula Pyramid has a greater volume.

Answer:

Step-by-step explanation:

We are given that

He makes number of attempted basket=9

We have to find the ratio which describes the number of baskets the player made to the number of baskets to play attempted.

[tex]\frac{number\;of\;baskets\;made}{number\;of\;basket\; to play attempted}=\frac{9}{15}[/tex]

[tex]\frac{number\;of\;baskets\;made}{number\;of\;basket\; to play attempted}=\frac{3}{5}[/tex]

Hence, the ration which describes the  number of baskets the player made to the number of baskets to play attempted=3:5

Final answer:

Given a sphere with a volume of 904.78 cm3, we find the radius to be approximately 6.13 cm, and the area of the largest cross-section, a circle, turns out to be approximately 118.08 cm2.

Explanation:

If the sphere has a volume of approximately 904.78 cm3, we can start by calculating the radius of the sphere using the volume formula for a sphere:

V = (4/3)πr3

Solving for r:

r = &Sqrt[3]{(3V)/(4π)} = &Sqrt[3]{(3×904.78 cm3)/(4π)} ≈ 6.13 cm

The largest cross-section of the sphere will be a circle with the diameter equal to the diameter of the sphere, hence the area A of this circle will be:

A = πr2 = π×(6.13 cm)2 ≈ 118.08 cm2

Therefore, the approximate area of the largest cross-section of the sphere is 118.08 cm2, which is not listed among the provided options, implying a possible typo or error in the options. Option closest to the calculated area is B) 113.1 cm2.

Answer:

504 in³

Step-by-step explanation:

this is a rectangular prism and the volume formula is v = l * h * w

so now

v = l*w*h

v= 6*8*12

v = 576 inch³

that's not the answer, that's the volume for whole thing but there is a gap and we have to subtract it from the whole volume. you can look at the option and say it's 504 inch³ from common sense. here is the work:

the gap has 2 inch length, 6 inch width and 6 in height.

v = l*h*w

v = 6 * 2 * 6

v= 72 inch

now subtract the gap volume from total volume so

576 - 72 = 504 in³
