<span>−13b=9
divide both sides by -13
</span><span>−13b/-13 =9/-13
simplify
b = -9/13</span>

To solve: -13(9)
b = -117

All you do is substitute 9 for b in the equation. Then you multiply both numbers and you get -117. Hope this helps.

If you divide 35 (amount of detergent in the container )into 1.25 (the 1 1/4 cups) your answer would be that you can do 28 loads , and if you had 3 boxes you would be able to do 84 loads because you just need to multiply the previous answer by 3

Find the measure of arc DC, in degrees, where the ? is shown. D ? 49° 70° с B

bazaltina [42]

Answer:

m(arc CD) = 122°

Step-by-step explanation:

Since, measure of an arc = 2 × (Angle subtended by the arc at the circumference of the circle)

m(arc CD) = 2[m(∠CBD)]

By triangle sum theorem in ΔBCD,

m∠CBD + m∠BDC + m∠DCB = 180°

m∠CBD + 49° + 70° = 180°

m∠CBD = 180° - 119°

m∠CBD = 61°

Therefore, m(arc CD) = 2 × 61°

m(arc CD) = 122°

Need help asap please! A toy company has determined that the revenue generated by a particular toy is modeled by the following e

Delvig [45]

The equation is r(x) = 10x - 0.025x² where x is measured in thousands of toys produced, and r(x) is measured in thousands of dollars.

For maximum r, r'(x) = 0

It becomes: r'(x) = $10-0.025\times2x=0$

= $10-0.5x=0$

$x=\frac{10}{0.05}$

x= 200

Hence, r(200) = $10\times200-0.025\times200^{2}$

Solving it we get,

r(200) = 1000

Hence, maximum revenue the company can earn with this toy is $1000.

How many ways can three people be selected from a group of seven people if order does matter

Alona [7]

Answer:

210 ways

Step-by-step explanation:

Given

$n = 7$ --- total

$r = 3$ --- selection

Required

In how many ways can be selection be done

Since orders does matter, then it is permutation.

This is calculated as:

$^nP_r = \frac{n!}{(n-r)!}$

So, we have:

$^7P_3 = \frac{7!}{(7-3)!}$

$^7P_3 = \frac{7!}{4!}$

Solve each factorial

$^7P_3 = \frac{7*6*5*4!}{4!}$

$^7P_3 = 7*6*5$

$^7P_3 = 210$
