the cost is given by the equation C=15.5m+30 where m is number of months and C is cost

if we want to find after 3 months, subsitute 3 for m and simplify

C=15.5(3)+30

C=46.5+30

C=76.5

the total cost will be $76.50

Natalie picked 135 berries in 15 minutes. If she continues picking at that rate, how long will it take her to pick 486 berries?

nikklg [1K]

We can use proportion to solve it
$135 berries -------------15min$
$486 berrier --------------x$
Our x is equal to = $x= \frac{486*15}{135} =54$ min
Its our result

What are the steps to construct parallel lines using a compass and straightedge?

nevsk [136]

See if the distance between the two lines is consistent with a compass.

Make sure the lines intersect at right angles with the corner of a piece of paper.

Measure each of the angles with a straightedge.

There is no way to ensure you have constructed parallel lines.

What is the exact value of x? 5⋅21^5x=16

IRINA_888 [86]

Answer:

x= 16 /20420505

Step-by-step explanation:

Let's solve your equation step-by-step.

5(215)x=16

Step 1: Simplify both sides of the equation.

20420505x=16

Step 2: Divide both sides by 20420505.

20420505x /20420505 = 16 /20420505

x= 16 /20420505

The measure of angle A to the nearest tenth of a degree is: A 18.5 B 19.5 C 20.5

Andrew [12]

Answer:

Step-by-step explanation:

This is a right triangle as shown by the right angle.

The side opposite the right angle is the hypotenuse, which is 9.
The side opposite angle A is 3.

So we have the opposite of A and the hypotenuse.

The trigonometric ratio that relates opposite side to hypotenuse is SINE.

$sin\theta=\frac{opposite}{hypotenuse}$

Since, we need angle A, $\theta$ is A, opposite side is 3, and hypotenuse is 9, we substitute:

$sinA=\frac{3}{9}\\sinA=\frac{1}{3}$

To solve for the angle, we use our calculator and find the inverse sin of $\frac{1}{3}$ :

$A=sin^{-1}(\frac{1}{3})\\A=19.47$

Rounding to nearest tenth of a degree:

$A=19.5$

B is the right choice.
