  no

Step-by-step explanation:

On average, there are about 173 1/3 hours per month, so James's take-home pay will be about ...

  ($15.50/h)(173 1/3 h/mo)(1 -26%) = $1988.13

His proposed rental is about ...

  1400/1988.13 · 100% = 70.4%

of his take-home pay.

Most financial planners would recommend the percentage be well below 50%. It is unlikely James can make his proposed monthly payments.

Answer:

I think it is A and C if I am correct how that helps

Answer:

1/2

0.5

50%

Step-by-step explanation:

The square  is spilt into 2 equal pieces, one out of the 2 is shaded therefore 1/2 is shaded. The decimal to represent the shaded area would be 0.5, as 1 times 1/2 = 0.5. As a percent the shaded area represents 50% as 1/2 times 100 (per cent = per hundred) is equivalent to 50.

I hope this helps :0).

Answer:

36/ (9 - 3) = 6

Cause:

9 - 3 = 6

Then:

36/6 simplified equals 6

So, your answer is 36/(9 - 3) = 6

Hope it helps! Good luck friend! :3

Answer:

36 / (9 - 3) = 6

Step-by-step explanation:

If you put the parentheses around 9 - 3, that will give you 6. 36 divided by 6 = 6. Also, in PEMDAS, Parentheses comes first, so  that is why the parentheses go there to make this true.

Answer:

13/20 Hours

Step-by-step explanation:

you have to find a common denominator. (20) You do 4x5 and 5x4 both equal 20. Then you do 1x5=5 and 2x4=8 then 8+5=13  then you make your fraction which is 13/20.

Answer:

Is it x = 85

196 +2x+(3x-6)

subtract 196 on both sides

simplify

add 6 on both sides

divide by 2

Answer: they’re both 53

Step-by-step explanation:

2320mi(5cm/120mi)=96.66cm

So the length is rounded to 97cm

Answer:

1) x = 5

2) y = 5·√2

Step-by-step explanation:

1) The given parameter of the right triangle are;

The legs of the right triangle = 'x', and 5

One interior angle of the right triangle = 45°

Therefore, buy the interior angle summation property of a right triangle, we have;

The measure of the other angle, θ = 180° - 90° - 45° = 45°

From which we have;

A right triangle with an interior angle of 45° is an isosceles triangle with both legs equal

∴ The length of the other leg, x = 5

x = 5

2) By Pythagoras's theorem, we have that the square of the length of the hypotenuse, 'y', is given as follows;

y² = x² + 5²

∴ y² = 5² + 5²

y = √(5² + 5²) = √(25 + 25) = √50 = √(25 ×2) = 5·√2

y = 5·√2 in the simplest radical form.

Answer: x+3+ 18/x-3

Step-by-step explanation:

The complete division problem can be written as:

(x² + 9) / (x-3) = x + 3 + 18/(x-3)

In mathematics, divides left-hand operands into right-hand operands in the division operation.

To divide using synthetic division, we follow these steps:

Write the dividend (x² +9) and the divisor (x-3) in the form of a long division problem, with the divisor (x-3) written on the outside and the dividend (x² +9) written inside the division brackets.

Write the coefficient of the first term of the dividend (in this case, 1) in the first row of the synthetic division. This will be the first term of the quotient.

Multiply the divisor (x-3) by the coefficient in the first row (1), and write the result (x-3) in the second row.

Add the second term of the dividend (9) to the result in the second row. The result is the coefficient of the second term of the quotient.

Repeat this process until you have found the coefficients of all the terms in the quotient.

Using this process, we can divide (x² +9) by (x-3) as follows:

The quotient is x + 3. The remainder is 18, so the complete division problem can be written as:

(x² + 9) / (x-3) = x + 3 + 18/(x-3)

#SPJ2

Answer:

y = 3x + 11

Step-by-step explanation:

obviously since y is 11 when x is zero the constant term is 11.

Then use the other coordinates to find the cooefficent of x.

-4= c × -5 + 11

-4= -5c + 11

5c=15, c=3

Therefore the equation should be:

y= 3x + 11

Answer:

Henry can write 13 pages in 8 hours.

Step-by-step explanation:

Rate: 5 pages in 3 hours (5/3 pages per hour)

To obtain the quantity of pages in 8 hours, we have to multiply the rate per hour by 8.

5/3 x 8 = 40/3= 13.34

Rounded to the nearest number, Henry can write 13 pages in 8 hours.

Answer:

7.45

Step-by-step explanation:

We are given a right triangle with one side length known and an angle know so we can use some trigonometry.

You need to find the hypotenuse so you are going to use either sine or cosine.

Since the adjacent from the angle is given (SOH-CAH-TOA) we can use cosine so,

cos(20) = 7/h

=>h = 7/cos(20)

=> 7.44924

=> 7.45

Answer:Initial number of trees (t)=204

Step-by-step explanation:

t = initial number of trees

Subtract 5 trees from the initial number of trees

we have,

t-5

each remaining tree made 210 oranges for a total of 41,790 oranges

We have,

(t-5) * 210=41790

Solve the equation

(t-5) * 210=41790

Open the bracket

210t-1050=41790

210t=41790+1050

210t=42840

Divide both sides by 210

210t/210=42840/210

t=204

The initial number of trees on MacDonald farm orange trees (t)=204

If 5 is removed from the initial trees

t-5=204-5

=199 trees

199 trees produce 210 oranges

We have,

199*210=41790 oranges

Answer:

£ 6,564.70

Step-by-step explanation:

Henry places £6000 in an account which pays 4.6% compound interest each year. Calculate the amount in his amount after 2 years

Compound Interest formula =

A = P(1 + r/n)^nt

A = Final Amounrt

P = Principal = £6,000

r = Interest rate = 4.6%

t = Time in years = 2 years

n = Compounding frequency = Yearly = 1

First, convert R percent to r a decimal

r = R/100

r = 4.6%/100

r = 0.046 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 6,000.00(1 + 0.046/1)^(1×2)

A = £ 6,564.70

The amount in his account after 2 years = £ 6,564.70

45+67=112

112*2= 224
