Answer 2

Answer:

25x5

Step-by-step explanation:

It is 25x5 because that is in the parantheses and when doing these types of problems you do multiplication first not addition. I use PEMDAS which stands for parantheses, exponents, multiplication, division, addition, and subtraction.

Answers

Answer:

The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m(x-a) is essentially different from the other two forms and means slope m and x-intercept (instead of y-intercept) a.

Drew made $18 per hour. Then he got a 10% raise. After cutbacks, he then had to reduce his hourly rate by 3%. What is his hourly rate after the cutbacks?

Answers

Answer:

19.206

Step-by-step explanation:

First you need to find out 10% of 18.

You can do that by 18/100 which is .18.

Then multiply that by 10 which is 1.8 (10% of 18)

His hourly rate decreased by 3% AFTER his raise so you would find 3% of 19.8 and not 18.

You do the same process and divide 19.8/100

Then multiply this by 3 and you can get 0.594

That is how much his raise decreased by so you would subtract it from 19.8

19.8 - 0.594 = 19.206 (Round if needed)

Hope this helps

now to the red part

2 x 1.5 = 3

now the blue

r^2 * pi = a

2^2 * 3.14

4 * 3.14 = 12.56

now add red and blue

3 + 12.56 = 15.56

now subtract that sum from the whole

60 - 15.56 = 44.44

now do

44.44 / 10 = 4.444

now see how much it would cost for the grass

4.444 * 4.60 = 20.4424 ≈ 20.44

A fitness club is having a special sale where you pay $27 to join plus a $8.00 monthly fee. You have $75.00 to spend. Write and solve the equation to determine how many months you can use the fitness club.

Answers

Answer:

6 months

Step-by-step explanation:

27 + 8x = 75

x = months which is what you're trying to figure out

1. subtract 27 from 27 and 75

2. then you have 8x = 48

3. divide both sides by 8 so x=6

4. 6 months

Answer:

27 + 8 x 6 = 75$. You can spend 6 months at the fitness club.

Step-by-step explanation:

What is the value of x in the figure? Enter your answer in the box.

Answers

Answer:

x = 65

Step-by-step explanation:

(2x +15)= 145

      -15      -15    subtract 15 from each side

2x = 130130/2 = 65  therefore x=65
Okay so these are vertical angles, which means that they are going to be equal to each other, aka CONGRUENT.

This means that your equation is going to be:

2x + 15 = 145

Now let us solve that equation.
You are going to subtract 15 from each side, so subtract 15 from 15, and subtract 15 from 145, meaning that your new equation is going to be:

2x = 130

Now your are going to divide each side my 2. This means you are going to divide 2x by 2 and divide 130 by 2. This means:

x= 65.

Donna made 2 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for both necklaces was $10.20. If the beads cost $3.20 for each necklace, how much did each pendant cost?

Answers

Each pendant costs $1.90. The total costs to make the 2 necklaces (beads and pendant) is $10.20. You have to find how much the beads cost for BOTH necklaces so you would solve $3.20 x 2. You would get $6.40. So now you subtract $6.40 from $10.20 to find how much the pendant for both necklaces cost. That would be $3.80 now you just divide by 2 to find the cost of 1 pendant.

The figure is made up of hemisphere and a cylinder.
what is the exact volume of the figure?
box [] cm^3

Answers

Answer:

Data: (Cylinder)

h (height) = 8 cm

r (radius) = 5 cm

Adopting:

V (volume) = ?

Solving:(Cylinder volume)

Note: Now, let's find the volume of a hemisphere.

Data: (hemisphere volume)

V (volume) = ?

r (radius) = 5 cm

Adopting:

If: We know that the volume of a sphere is , but we have a hemisphere, so the formula will be half the volume of the hemisphere

Formula: (Volume of the hemisphere)

Solving:

Now, to find the total volume of the figure, add the values: (cylinder volume + hemisphere volume)

Volume of the figure = cylinder volume + hemisphere volume

Volume of the figure = 628 cm³ + 261.6 cm³

An object is augmented if the scale factor is more noteworthy than 1. An article is decreased if the scale factor is a division, under 1.
