Ber [7]

So 16 = 3.6, 10 = 2.3 so 20 = 4.6 then add 16 + 20 to get 36 so 3.6 + 4.6 = 8.2
36 ounces = 8.2 cups

36 = 8.2, 8 = 1.8, 20 = 4.6, 36 + 8 + 20 = 64 ounces so 8.2 + 1.8 + 4.6 = 14.6 cups
64 ounces = 14.6 cups

Total cups = 8.2 + 14.6 = 22.8 cups

The scale model of a car is 5% of the size of the actual car. The length of

podryga [215]

<h3>Answer: 15 feet</h3>

Explanation:

x = length of the actual car in inches

5% of x = 9 inches

0.05x = 9

x = 9/(0.05)

x = 180 inches

Divide by 12 to convert from inches to feet.

180 inches = (180/12) feet = 15 feet

On a coordinate plane, a line goes through (0, negative 1) and (3, 1). a point is at (negative 3, 0). what is the equation of th

Vitek1552 [10]

Required Equation is $y = \frac{2x}{3}+2$

Given: A line passing through $({x}_1,{y}_1)$ and $({x}_2,{y}_2)$

Slope = $\frac{(y_2 - y_1)}{(x_2 - x_1)}$ = $\frac{( 1 - (-1))}{(3 - 0)}= \frac{2}{3}$

Equation of line is:

$Y_1(x) = \frac{2}{3}x + b$

Where b is y intercept

for value of b

$Y_1(0) = -1 = \frac{2}{3}*0 + b = b$

⇒ b = -1

and Equation of line is:

$Y_1(x) = \frac{2}{3}x + (-1)$

For another parallel line that passes through the point (-3,0)

$Y_2(x)= \frac{2}{3}x + c$

$Y_2(-3) = 0 = {2}{3}*-3 + c = -2 + c = 0$

c = 2

then the equation is:

$Y_2(x) = \frac{2}{3}x + 2$

Show that the equation x cubed + 8x = 30 has a solution between x = 2.2 and x =2.3 ?

tatuchka [14]

$x^3+8x=30\\
x^3+8x-30=0\\\\
2.2^3+8\cdot2.2-30=10.648+17.6-30=-1.752\\
2.3^3+8\cdot2.3-30=12.167+18.4-30=0.567
$

For $x=2.2$ the value of $x^3+8x-30$ is negative, and for $x=2.3$ the value is positive which means between $x=2.2$ and $x=2.3$ there is an x for which the value of $x^3+8x-30$ is equal to 0 and therefore there is a solution.
