Answer:

x = 8

Step-by-step explanation:

Use the direct variation equation, y = kx

Plug in the given values of x and y, and solve for k:

y = kx

-8 = k(-2)

4 = k

So, the equation is y = 4x

Using this, plug in 32 as y, and solve for x:

y = 4x

32 = 4x

8 = x

So, x = 8 when y = 32

Step-by-step explanation:

cuz both of the quadrilaterals have the same angles and all angles equal 360 °

Answer:

She would make $35.

Step-by-step explanation:

If you do 10 x 3.5, you will get the answer of $35.

Answer:

$30

Step-by-step explanation:

She would be getting paid by the HOUR, and she has worked 3.5 hours. If she gets paid every HOUR, that means that she would be paid three times when working 3.5 hours. The answer would be $30.

The person who wrote the question might want $35 dollars as the answer, but logically the answer should be $30.

Answer:

x = 48

Step-by-step explanation:

From the given diagram, the sum of the angles given is equal to 180 degrees as shown;

x+y+2x = 80

Since y = 36

x +36+2x = 180

3x = 180 - 36

3x = 144

x = 144/3

x = 48

Hence the value of x is 48

Answer:

Step-by-step explanation:

The equation of the line in slope-intercept form:  y = mx + b, where m is a slope and b is y-intercept

Slope of  line that passes through two given points:  [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

(0, 8)    ⇒    x₁ = 0,  y₁ = 8

(3, 3)      ⇒    x₂ = 3,  y₂ = 3

[tex]\bold{m=\dfrac{3-8}{3-0}=\dfrac{-5}3=-\dfrac53}[/tex]

b = 8

Therefore the equation:   y = -⁵/₃x + 8

Answer:

72

Step-by-step explanation:

1/3 ft is 4 inches

24 feet is 288 inches

take 288 and divide it by 4

you get 72, which is the number of pieces of chain Andrew has

Answer:

No, 12 is greater than -40

Step-by-step explanation:

Answer: I think your question is: Is negative forty greater than positive 12. It is not greater. Even if it was negative 40 and negative 12 it still would not be greater. Hope this helps :)

Answer:

1.39

Step-by-step explanation:

Given the quadratic equation :

2x^2+3x-8 = 0

We could apply the quadratic equation formula :

a = 2 ; b = 3, c = - 8

The formula is stated as :

-b±sqrt(b² - 4ac)/2a

To save computation tune, we could use a calculator :

The roots are : - 2.886 ; 1.386

The positive solution rounded to the nearest hundredth is : 1.39

Answer:

18sqrt5  or 40.249

Step-by-step explanation:

by pythagorean theorem

Hypotenous^2=altitude^2+base^2

c^2=a^2+b^2

c^2=(18)^2+(36)^2

c^2=324+1296

c^2=1620

taking sqrt root

c=18sqrt5=40.249

Answer:

in right angled triangle BCD

by using Pythagoras law

P²+B²=H²

A²+B²=C²

36²+18²=x²

x=√1620=18√5m

x=18√5 m is your answer

Answer:

Purple Diamond = 2  Green Moon = 7.5 Pink Trapezium = 30

Step-by-step explanation:

T = Pink Trapezium

D = Purple Diamond

M = Green Moon

Line 1 = T = 30 x 1 = 30

Line 2 = (D x D) x (M) = (2x2) x (7.5) = 4 x 7.5 = 30

The key is the weight of the line multiples to 30

Just like graphs do with x/y

If x is horizontal then y is vertical

= x/y we get the gradient which is the same as division or dividing 30/30 = 1 being the base weight amount

and same as 30/7.5 = 4 and simplifying 4 to (2 x 2)that means an easier way to see the number of (2x2) being the base weight = 1 x 2  then 1 x 2 then as we have found 4 its simplification we can divide it into 30 to show 30/4 = 7.5 for the Moon or for (M) above.

The 4 number is simplification and (+ 2 )(+ 2) is its factorization before it turns to 30 to show 30 = (2 x 2 x 7.5)  or 2^2 x 7.5 = 30. Etc. Etc.

Question:

The shaded portion of the bar model in Part A shows 3/8. What percent is equivalent to 3/8? Enter the correct answer in the box.

Answer:

The equivalent is 37.5%

Step-by-step explanation:

Given

[tex]\frac{3}{8}[/tex]

Required

The equivalent

The model is not shown, but the question can still be solved.

We have:

[tex]\frac{3}{8}[/tex]

Multiply by 100%

[tex]\frac{3}{8} = \frac{3}{8} * 100\%[/tex]

[tex]\frac{3}{8} = 0.375 * 100\%[/tex]

[tex]\frac{3}{8} = 37.5\%[/tex]

Horace measured a circular lid and found d, the diameter, was 8 inches and C, the circumference, was 25 inches. Which expression represents an approximate value for pi?

Answer:

pi = 3.125

Step-by-step explanation:

We are given;

Diameter; d = 8 inches

Circumference; C = 25 inches

Formula for circumference of a circle is;

C = πd

We are trying to find the value for pi(π)

Thus; π = C/d

π = 25/8

π = 3.125

JUST USE THE CALCULATOR DUHHH!!!
