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:

8÷(x+3)

Step-by-step explanation:

it doesnt specify what number you add with 3 so you substitute it with a variable such as x.

The sum is adding so x +3 and then divide by 8

Answer:

f(3)=1

Step-by-step explanation:

take f(x)=2(x)-5

put a three wherever you see an x in parentheses

f(3)=2(3) - 5

simplify

f(3)=6-5

simplify

f(3)=1

answer:f(3)=1

Answer:

f(3) = 1

Step-by-step explanation:

You substitute 3 for x.

f(3) = 2(3) - 5

Multiply the 2 terms.

f(3) = 6 - 5

Subtract.

f(3) = 1

Given:

The distance flown was 135 km.

The average speed was 180 km/h.

To find:

The time taken by the airplane.

Solution:

We know that,

[tex]Speed=\dfrac{Distance}{Time}[/tex]

[tex]Time=\dfrac{Distance}{Speed}[/tex]

Putting Distance = 135 and Speed = 180, we get

[tex]Time=\dfrac{135}{180}[/tex]

[tex]Time=0.75[/tex]

The time taken by the airplane is 0.75 hours.

We know that,

1 hour = 60 min

0.75 hour = 0.75 × 60 min

0.75 hour = 45 min

Therefore, the time taken by the airplane is 45 min.

Answer:

11 + n

Step-by-step explanation:

sum means addition, so u need a + sign

n is usually the variable used for 'a number'

so 11 and (+) a number (n) = 11+ n

Easy!

4 units x 4 is

16

Answer:

Step-by-step explanation:

First, we need to find the hypotenuse, so we need to apply the equation from the Pythagorean Theorem

A^2+B^2=C^2.

We know A^2 and B^2, so we need to substitute that into the equation

2^2+4^2=C^2

so now, simplify.

4+16=C^2

20=C^2

Square root of 20 is about 4.5

so 4.5 is the length of the sides of the square.

4.5x4.5=20.25

Answer: 384 uniforms

Step-by-step explanation:

There are 127 employees and each of them will need 3 uniforms. The uniforms needed in total will be:

= 127 * 3

= 381 uniforms

Uniforms are however, ordered in packages of 8.

= 381/8

= 47.6

They have to order a multiple of 8. Round up the figure above to find the nearest multiple of 8:

= 48 * 8

= 384 uniforms

Answer:

3060 degrees

Step-by-step explanation:

The formula is  (n-2)*180  

Plug the 19 in (19 - 2) * 180 = x  

17 * 180 = 3060 degrees

17. the sum of the lengths of any two sides of a triangle is always greater than the length of the third side

T=the third side

12+18>T

12+T>18

18+T>12

the first equation says that T<30

the second equation says that T>6

putting these together...

6<T<30

Answer:

yes

Step-by-step explanation:

you plug in (2,8) so 8 = y and 2=x.

so 8=4(2) 8=8 which is correct

then 8= 2+6 8=8 which is correct

Area of the rectangle = L X W

Area of the rectangle = 4 X 2

Area of the rectangle = 8 inches

If the drawing is 1/5 of the actual air conditioning unit, then you multiply the reciprocal which is 5 times the area of the drawing. When you want to enlarge it has to be a whole number. When you want to reduce you multiply by a fraction.

So 8 inches X 5 = 40 inches is the actual area of the unit.

Step-by-step explanation:

18000

Step-by-step explanation:

5000*12%= 600 600× 30= 18000 15 years semi annually = 30 x

The compound interest on $5,000 at 12% interest for 15 years compounded semi-annually is $22,243.58

To find the compound interest on $5,000 at 12% interest for 15 years compounded semi-annually, we can use the formula:

A = P(1 + r/n)^(n*t)

where:

P = principal amount = $5,000

r = annual interest rate = 12% = 0.12

n = number of times compounded in a year = 2 (compounded semi-annually)

t = time period in years = 15

A = amount after t years

Plugging in the values, we get:

A = 5000(1 + 0.12/2)^(2*15)= $27,243.58

So, the amount after 15 years is $27,243.58. To find the compound interest, we can subtract the principal amount from the amount after 15 years:

Compound interest = A - P

= $27,243.58 - $5,000

= $22,243.58

Therefore, the compound interest on $5,000 at 12% interest for 15 years compounded semi-annually is $22,243.58.

Answer:

y = 2x - 7

y = - x - 1

So 0 = - 3x + 6

So - 3x = - 6

So x = 2

And y = 2 × 2 - 7 = - 3

So (x, y) is (2,-3)

Answer:

65 is x

Step-by-step explanation:

the equation is 2x+50=180 remember line measures 180 degrees that is why the equation also equal 180.

Answer:

x = 65

Step-by-step explanation:

The line is a 180 degree so 180- 50 = 130

130 / 2 = 65

2 x 65 = 130

X = 65
