Answer:

b=3

Step-by-step explanation:

Isolate the b:

8-5b=-7Subtract 8, -5b=-15Divide by -5, b=3

Check your answer:

8-5(3)=-78-15=-7-7=-7
Answer 2
b=3
you subtract the 8 from the left then subtract it from the right giving you -5b=-15 then divide the -5 by both sides

Answer:

$367.38 is the cost to stain the entire deck.

Step-by-step explanation:

Here is what you need to know beforehand:

Diameter is a line that goes through a circle. Radius is a line that goes from the edge of the circle all the way to the center/a line that goes halfway through the circle.

--------------------------------------------------------------------------------------------------------------

First, find the area of the circle. Here is the formula:

Area = 3.14 (Pi) x r²

Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m

So the formula will look like this:

Area = 3.14 x 6²

Then, you just do the math:

Area = 3.14 x 6²

Area = 3.14 x 36

Area = 113.04

The goal of the problem is to find the amount of money Emma needs. Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:

Answer = 113.04 x 3.25

Answer = 367.38

$367.38 is the cost to stain the entire deck.

[tex]3.5 \times 6 + (5 - 3.5) \times 6 \div 2 = \\ = 21 + 9 \div 2 = \\ = 25.5[/tex]

Answer:

25.5m

Step-by-step explanation:

square area: 6m*3.5m = 21m

Triangle height: 5m - 3.5m = 1.5m

Triangle area: [tex]\frac{1.5m*6m}{2}[/tex] = 4.5m

Total area: 21m + 4.5m = 25.5m

0.75 of the adults in a hall are women. If there are 125 men, how many adults are there altogether?

Answers

I think the answer is 500
If there are x adults total, and 0.75 of them are women, then you have 0.75x women total. it is given that you have 125 men.
since men plus women equals total adults, 0.75x+125=x
125=0.25x
x=500

You made Marcellus 3 times as tall as Dan but you dragged Marcellus’s eyes to be 1 times as far apart as Dan’s eyes. A scale giant would have the same multiple for both.

If Dan's eyes are 5 cm apart, how many centimeters apart should Marcellus's eyes be?

Answers

If you dragged Marcellus’s eyes apart 1x farther than Dan’s eyes then they would both have eyes that are 5cm apart because 5 x 1 = 5

Marcellus's eyes should be 5 cm apart

If Marcellus eyes are 1 times as far apart as Daniels eyes. We can write this mathematically as;

Marcellus eyes are 1x far apart as Dan's eyes.

If we spin this over, we are told that Dan's eyes is 5 cm apart. How far apart would Marcellus's be.

Marcellus eyes will be Dan's eyes divided by the mathematical equivalent we wrote the other time, which is 1 times.

Essentially, Marcellus's eyes will be just as wide as Dan's eyes

Each 5 minutes represent 1 mile. This can be also referred as independent and dependent variables. It takes 5 minutes for 1 mile. Or T=5m (m=minutes) D=1

so 5 x 2 (5 minutes x 2) = 10 minutes and 10 minutes equal to 2 miles, each 5 minutes is another mile. For example, 60 minutes (1 hour) 60 divided by 5 = 12 so in 1 hour (60 mins) equal to 12 miles in total! hope this helps at least a bit! :)

In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force. Though both force and displacement are vector quantities, work has no direction due to the nature of a scalar product (or dot product) in vector mathematics. This definition is consistent with the proper definition because a constant force integrates to merely the product of the force and distance.
