Answer: 56 kids

Step-by-step explanation: 70 * 0.2 = 14      70 - 14 = 56

Last year we tested 70 kids on Unit 8 and this year we tested 20% less kids then we tested 56 kids on Unit 8 this year.

percentage, a relative value indicating hundredth parts of any quantity.

If we tested 20% less kids this year, it means we tested only 80% of the number of kids we tested last year.

To find out how many kids we tested this year, we can use the following equation:

number of kids tested this year = 0.8 × number of kids tested last year

Substituting the given values, we get:

number of kids tested this year = 0.8 × 70

number of kids tested this year = 56

Therefore, we tested 56 kids on Unit 8 this year.

Step-by-step explanation:

calculate the slope m of the 2 points from the origin and equate, since they lie on the same line

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

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (2, k )

m = [tex]\frac{k-0}{2-0}[/tex] = [tex]\frac{k}{2}[/tex]

repeat with

(x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = k, 32 )

m = [tex]\frac{32-0}{k-0}[/tex] = [tex]\frac{32}{k}[/tex]

equating the 2 slopes

Answer:

total num playing video games/total no of studen×100

a) 43%

b) 49%

Answer:

1500 people.

Step-by-step explanation:

100% of the fans are not known,

So let the total number of fans or 100% of the fans be X

SINCE 10% ••••••••••• 150

100% ••••••••••••X

we're going to Cross multiply

= 10×X = 100 × 150

10X = 15000

dividing bothsides by 10

10X/10 = 15000/10

X = 1500 people.

well, the shape is a trapezoid, a trapezoid has two parallel sides only, the parallel sides are called "bases", and the distance between the parallel sides is its "height".

Answer:

m<S = 68 degrees.

m<D = 112 degrees

Step-by-step explanation:

Opposite angles of a parallelogram are equal so:

4x - 4 = 3x + 14      

4x - 3x = 14 + 4

x = 18.

So m < S = 4(18) - 4

= 72-4

= 68 degrees.

Angles on the same side of a parallelogram are supplementary, so

m < D = 180 - 68

= 112 degrees.

The age of Marissa and her younger brother.

We know that the older brother's age is 18 and he is twice older than the younger brother.

Let the unknown be "x"

[tex] x=\frac{18}{2} [/tex]

[tex]\large\boxed{\sf{x=9 \: years}}[/tex]

Now, we know that the younger brother's age is 9 and Marissa is 3 years older than him.

Let the unknown be "x"

[tex]x=9 + 3[/tex]

[tex]\large\boxed{\sf{x=12 \: years}}[/tex]

Therefore, Marissa is 12 and her younger brother is 9

Answer:

Marissa's age = 12

Younger brother's age = 9

Step-by-step explanation:

Let age of Marissa be x, and her younger brother's y.

Equations formed :

Finding age of younger brother using Equation 2 :

⇒ 2y = 18

⇒ 2y/2 = 18/2

⇒ y = 9 years old

Substituting y in Equation 1 :

⇒ x = y + 3

⇒ x = 9 + 3

⇒ x = 12 years old

Marissa's age = 12

Younger brother's age = 9

Step-by-step explanation:

The surface area of the cone is the amount of space on it, the radius of the cone is about 13 feet

The given parameters are:

The surface area is calculated using:

[tex]A =\pi r(r + \sqrt{h^2 + r^2})[/tex]

So, we have:

[tex]A =\pi r(r + \sqrt{(3r)^2 + r^2})[/tex]

Substitute 2167 for A

[tex]2167 =\pi r(r + \sqrt{(3r)^2 + r^2})[/tex]

Evaluate the sum

[tex]2167 =\pi r(r + \sqrt{10r^2})[/tex]

Divide both sides by [tex]\pi[/tex]

[tex]689.78 =r(r + \sqrt{10r^2})[/tex]

Evaluate the exponent

[tex]689.78 =r(r + 3.16r)[/tex]

Evaluate the sum

689.78 =r(4.16r)

Open the bracket

689.78 = 4.16r²

Divide both sides by 4.15

r² =165.8125

Take the square root of both sides

r = 13 (approximated)

Hence, the radius of the cone is about 13 feet

Answer:

y = 1/3*x -3

Step-by-step explanation:

Method 1:

Grab two random points from the line.

(0,-3) and (3,-2)

Using the Point-Slope Form solve for m.

(-3 - (-2)) = m * (0 - (3))

-1 = m * (-3)

m = 1/3

Turning Point-Slope form into Slope intercept Form.

(y - (-3)) = 1/3 * (x - 0)

y + 3 = 1/3x

y = 1/3 - 3

Method 2:

Look at the y-intercept since y-int becomes our b. b = -3

From the y-int count rise/run as thats our Slope m. m = 1/3

Slope-intecept Form:

y = 1/3*x -3

Answer:

y=1/3x-3

rise/run= 1/3

y-int. is -3
