so he bought 720 bolts

Question

What the expression (4f-3+2g)-(4g+2)

Solution 1

For this question you can say:

4f -3 +2g - 4g -2

so now you can simplify and find the answer:

4f -3 -2g -2 = 4f -2g -5

and that's the answer :)))

I hope this is helpful

have a nice day

4f -3 +2g - 4g -2

so now you can simplify and find the answer:

4f -3 -2g -2 = 4f -2g -5

and that's the answer :)))

I hope this is helpful

Solution 1

Therefore, the **speed **of the car in m/s is m/s i.e., option (B) is correct.

**What is the equation?**

The definition of an **equation **is a mathematical **statement** that shows that two mathematical **expressions **are **equal**.

Here given that,

A car is **traveling **at a speed of km/h.

As we know,

So,

km/h= m/s

Hence, the **speed **of the car in m/s is m/s i.e., option (B) is correct.

I think the answer is B

Question

Is 8 yd greater than 288 in.

Solution 1

3 feet is equal to 1 yard and 3 feet is 36 inches. 288 inches divided by 36 is 8 so 8 yards is equal to 288 inches.

Solution 2

I believe they are the same since one yard is 36 in, so 8x36 is 288. Hope i helped :)

Question

So I have a question, this : Insert 2 grouping symbols to make the equation true 100 + 4 * 6 + 3 - 27 / 9 - 6 = 127
Where do I put the grouping symbols?

Solution 1

Between 4 and 6 is where u put the grouping symbols!

Question

Simplify and factories 16g + 32h - 48g - 40h

Solution 1

For this question you can say:

16g - 48g = -32g

and 32h - 40h = -8h

so you will have:

-32g - 8h and you can factor -8 so you will have:

-8(4g + h) :)))

i hope this is helpful

have a nice day

16g - 48g = -32g

and 32h - 40h = -8h

so you will have:

-32g - 8h and you can factor -8 so you will have:

-8(4g + h) :)))

i hope this is helpful

have a nice day

Question

Find the value of sin2a, if tana=-12/5 in the fourth quadrant

Solution 1

Recall the following identities:

from which we get

Since is in the fourth quadrant we know that should be positive, so when we take the square root here, we should take the positive root.

Now recall that

and since is in the fourth quadrant, we expect to be negative. So,

One final identity:

from which we get

Question

the weight of a nickel is 80% of the weight of a quarter.if a nickel weighs 5grams how much does a quarter weigh?

Solution 1

Just divide 100% by 80% and multiply that answer by 5. I'm pretty sure that's how you do it.

Question

The Mulraney's home has 2,550 square feet of living space. A contractor is building an addition to their home that will increase the square footage by 8%. What will be the square footage of their home with the addition?

Solution 1

First we have to find out how much the Mulraney's square footage increases with the addition. To do this, we should multiply the percent of expansion, 8% (0.08) by their current square footage (2, 550)

0.08 * 2,550 = 204

This means that the addition is adding 204 square feet to the Mulraney's house.

To find the total number of square footage, we just add the original (2,550 feet) to the addition (204).

2,550 + 204 = 2754

Therefore,**the square footage of the Mulraney's home with the addition is 2754 square feet.**

0.08 * 2,550 = 204

This means that the addition is adding 204 square feet to the Mulraney's house.

To find the total number of square footage, we just add the original (2,550 feet) to the addition (204).

2,550 + 204 = 2754

Therefore,
