would need more than 5.25 intest rate. so what you would have to do is subtract 750 from 199,00 then once you have that you would have to find out how much YOU yourself would want to put down as a morgage.

How to solve 3(x+1)=5(x-2)+7

igor_vitrenko [27]

So first do 3(x+1) which is 3x+3 because you have to multiply the outside number by the stuff in side the parentheses. Then you do the 5(x-2)+7 and it should be 5x-10+7 so now your equation should be 3x+3=5x-10+7 now subtract the 3x from the 5x and now your equation should look like this: 3=2x-10+7. Then you add the 10 and the 7 so now your equation should look like this: 3=2x-3 because it's a -10 and a positive 7 it would be -3. So then you have to add the -3( which now becomes positive to the other 3 in front of the = sign. So now your equation should look like this: 6=2x. Now divide by 2 to get x by its self and now your answer should be 3=x or x=3.

You need to cover the playground of a child development center with mulch. the playground is 125 feet long and 60 feet wide. you

kirill [66]

The answer is 139 cubic yards

This mulch will be of cylindrical shape.
The volume (V) of a cylinder is:
V = l · w · h (l - length, w - width, h - height (in our example, height = depth)

It is known:
l = 125 feet
w = 60 feet
h = 6 inches = 0.5 feet

V = l · w · h = 125 · 60 · 0.5 = 3750 feet³

Since 1 cubic foot is 0.037 cubic yards, 3750 cubic feet are 139 cubic yards:
0.037 · 3750 feet³ = 138.75 cubic yards ≈ 139 cubic yards

The length of a log of wood is 90 in. How many cuts do you need to make to obtain

Ilia_Sergeevich [38]

The greatest number of pieces will be 12 where each piece will have a different length and the length of each piece is a whole number, in inches and the remaining piece length will be 12 in(90 - 78).

<h3>What is a sequence?</h3>

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

The total length of the wood = 90 in

We have to cut it into the greatest number of pieces, where each piece will have a different length and the length of each piece is a whole number, in inches.

We can cut it like:

1 in, 2 in, 3 in, 4 in, and so on

The above shows the arithmetic sequence,

The sum of the n natural number is given by:

$\rm S_n = \dfrac{n(n+1)}{2}$

$\rm 90 = \dfrac{n(n+1)}{2}$

After solving, we will get a quadratic equation:

n² + n -180 = 0

After solving, we will get:

n = 12.92 and n = -13.92(term can not be negative)

n = 12 (taking whole number)

Thus, the greatest number of pieces will be 12 where each piece will have a different length and the length of each piece is a whole number, in inches and the remaining piece length will be 12 in(90 - 78).

Which value is equivalent to: 1 1/2 divided by 4 1/2 x 1 1/3

Nostrana [21]

Answer:

The answer is 4/9

Step-by-step explanation:

Hi. Here's the work.

First turn everything into an improper fraction.

$1 \frac{1}{2}$ ÷ $4 \frac{1}{2} * 1 \frac{1}{3}$ = $\frac{3}{2}$ ÷ $\frac{9}{2} * \frac{4}{3}$

To divide fractions we multiply by the flipped version of the fraction, or the reciprocal.

$\frac{3}{2}$ ÷ $\frac{9}{2} * \frac{4}{3}$ = $\frac{3}{2} *\frac{2}{9} *\frac{4}{3}$

Now we just multiply the fractions!

$\frac{3 * 2 * 4}{2 * 9 * 3}$ = $\frac{4}{9}$

The answer is therefore 4/9. Please mark brainliest if possible and i hope you get a good grade on your homework. ;)

If a and b are two angles in standard position in Quadrant I, find cos(a+b) for the given function values. sin a=4/5 and cos b=5

vladimir1956 [14]

First let's find the angles a and b.

We have then:
sin a = 4/5
a = Asin (4/5)
a = 53.13 degrees.

cos b = 5/13
b = Acos5 / 13
b = 67.38 degrees.

We now calculate cos (a + b). To do this, we replace the previously found values:
cos ((53.13) + (67.38)) = - 0.507688738
Answer:
-0.507688738
Note: there is another way to solve the problem using trigonometric identities.
