49. I figure out these kind of questions a different way than taught. At least where I am. Divide the total amount by the amount of instances of multiplication so in this it would be 6x plus the 1 that the programmer types. This gives you 7. Decide then total (343) by seven then multiply by the multiplied amount, so the secretary would multiply by 6 and the programmer by 1. You get 49 for the programmer.

Which value of d is a solution to equation 2.2d + 5.4= 12

ryzh [129]

Hello!

<em><u>Answer:</u></em>

<em><u>d=3</u></em>

<em><u>*The answer must have a positive sign.*</u></em>

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, you multiply by 10 from both sides of an equation.

$2.2d*10+5.4*10=12*10$

Then, you had to refine the problem down.

$22d+54=120$

Next, you subtract by 54 from both sides of an equation.

$22d+54-54=120-54$

Simplify.

$22d=66$

You can also divide by 22 from both sides of an equation.

$\frac{22d}{22}=\frac{66}{22}$

And finally, simplify and solve. You can also divide by the numbers.

$66/22=3$

Final answer: → $d=3$

Hope this helps!

Thanks!

Find the volume of this sphere. Please help

natulia [17]

Hello there!

We've already given the formula so I will not be adding it here.

We are also given that π = 3 for this problem.

r is defined as 'radius'

Radius is a point from center to one of endpoints.

Look at the image, the radius is given as 7cm.

From the information we gathered:

π = 3
r = 7

Substitute in the formula.

$\displaystyle \large{ V = \frac{4}{3} (3) {(7)}^{3} }$

Cancel 3 out.

$\displaystyle \large{ V = 4{(7)}^{3} }$

Evaluate 7^3

$\displaystyle \large{ V = 4(343) }$

Multiply

$\displaystyle \large{ V = 1372 }$

Therefore, the volume is 1372.

Let me know if you have any questions!
