Answer:

Hi! You just have to take his salary as a unity (one) and substract the fractions you are given. For example; lets say you have a cake (one) and then you eat 1/8 of it. You would be left with  [tex]1-\frac{1}8}[/tex] of the original cake.

Step-by-step explanation:

Salary:     [tex]1[/tex]

Spent [tex]\frac{2}{5}[/tex] :     [tex]1-\frac{2}{5}[/tex]

Spent [tex]\frac{1}{4}[/tex]:      [tex]1-\frac{2}{5} -\frac{1}{4}[/tex]

Spent [tex]\frac{1}{8}[/tex]:      [tex]1-\frac{2}{5} -\frac{1}{4} -\frac{1}{8}[/tex]

REMAINING: [tex]1-\frac{2}{5} -\frac{1}{4} -\frac{1}{8}[/tex]

Operate using LCM:  [tex]\frac{40-16-10-5}{40} = \frac{9}{40}[/tex]

The answer is (d)

Answer:

b = 26

Step-by-step explanation:

As angles I and K are equal in the triangle, the sides opposing them should also be of the same length. Therefore, the value of b is equal to the side of the other side's measure, which is equal to 26.

Answer:

5 months

Step-by-step explanation:

Daniel's provider charges $60 for installation and $45.95 per month. Sydney's provider has free installation and charges $57.95 per month

Let x = number of months

Daniel = 60 + 45.95x

Sydney = 0 + 57.95x

Equate both equations

60 + 45.95x = 0 + 57.95x

Collect like terms

60 - 0 =57.95x - 45.95x

60 = 12x

Divide both sides by 12

x = 60 / 12

= 5

x = 5 months

Daniel and Sydney would have paid the same amount for high-speed Internet service after 5 months

Answer: -15^2

Step-by-step explanation: It goes down by -225 every time so the exponent form would be -15^2. Just keep on subtracting 225 every number. Add 225 for the 0x only.

Answer:

27

Step-by-step explanation:

every 30 men = 9 men with beards

you have 30 3 times in 90 so you get 27

60÷2=30

18÷2=9

30 men normal = 9 men with beards

90÷30=3

3×9=27

Answer:

27 is correct

Step-by-step explanation:

18 out of the last 60 men who walked by had a beard.

based on the given condition formulate

[tex]\boxed{\frac{18}{60}=\frac{x}{90} }[/tex]

[tex]\boxed{60x=18(90)}[/tex]

[tex]\boxed{\frac{18~x~90}{60} }[/tex]

[tex]\boxed{x=27}[/tex]

60÷2=30

18÷2=9

30 men normal = 9 men with beards

90÷30=3

how many of the next 90 men who walk by

you have 30 × 3  = 90 so you get 27

3 × 9 = 27

Therefore the correct answer is 27

Hope this helps!

Answer:

b

Step-by-step explanation:

the arc length is calculated as

arc = circumference (C) × fraction of circle , then

16 = C × [tex]\frac{45}{360}[/tex] = C × [tex]\frac{1}{8}[/tex] ( multiply both sides by 8 )

128 = C

circumference of circle is 128 cm

Answer:

612 quarts

Step-by-step explanation:

First, let's set up this situation into a proportion.

Now, let's simplify the proportion.

As you can see, we have to multiple one by thirty-six to get to thirty-six. Whatever we do the denominators, we have to do to the numerators. Thus, 17 multiplied by 36 is 612 quarts.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:

612 quarts

Step-by-step explanation:

If 170 quarts of ice cream is made in 10 hours. Then, in 1 hour (170/10) = 17 quarts of ice cream are made.

Therefore, in 36 hours (17×36) = 612 quarts of ice cream are made

Answer:

When you multiply a a decimal number by the integer 100 the decimal shifts only two places to the right.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

f(x) • g(x)

= [tex]\sqrt{x^2+12x+36}[/tex] × (x³ - 12)

= [tex]\sqrt{(x+6)^2}[/tex] × (x³ - 12)

= (x + 6)(x³ - 12)

= x(x³ - 12) + 6(x³ - 12) ← distribute parenthesis

= [tex]x^{4}[/tex] - 12x + 6x³ - 72

= [tex]x^{4}[/tex] + 6x³ - 12x - 72

Answer:

9²

Step-by-step explanation:

9 · 9 = 81

9² = 9 ·9

The expression  9X9 as a power is 9².

A number system is defined as a system of writing to express numbers.

We have to write 9X9 as a power.

Nine cross nine as power.

We know that nine is multiplied with nine we get eight one.

9×9=81

Here we used the operation multiplication.

Multiplication is a method of finding the product of two or more numbers

When two number with same base are multiplied then the powers will be added.

9×9

9¹⁺¹=9²

Hence, the expression  9X9 as a power is 9².

#SPJ2

Let's use j to represent Jiri's age.

If Pamela is 6 years younger that Jiri, her age can be represented by j - 6.

Since the sum of their ages is 64, we can setup the equation j + (j - 6) = 64.

Simplifying on the left, we have 2j - 6 = 64.

Adding 6 to both sides, we have 2j = 70.

Dividing both sides by 2, we have j = 35.

So Jiri is 35 years old and Pamela is 6 years younger or 29 years old.

Answer:

1) 7.069 cm^2

2) 12.567 cm^2

3) 19.635 cm^2

4) 3.142 yd^2

5) 38.485 yd^2

6) 50.266 yd^2

Step-by-step explanation:

This problem is a repetition of the formula Area = [tex]\pi[/tex]*[tex]radius^{2}[/tex]

You are given the diameter of each circle.  The radius is 1/2 of the diameter, so, for example circle 1 has a diameter of 3 cm which means the radius is 3/2 cm and the area is A = [tex]\pi * (3 cm /2)^{2}[/tex] = 7.069 cm^2

don't forget your units.  Either cm or yd squared

Answer:

slope is 1/4； y intercept is -2

Step-by-step explanation:

read your textbook carefully

you note that you are given two point the x-intercept and y-intercept:

(8,0) and (0,-2) respectively.

before doing exercise, you need to know what is the slope formula (read your book).

slope formula is the change in y over the change in x.

or you can perceive that slope mean when x move forward one unit, what is change in y( how many units the y move).

Answer:

4 1/8

Step-by-step explanation:

If you take 1 and multiply by 3, you get 3. Pretty simple. When you multiply 3/8 by 3, its also easy. You just multiply the top number. 3 times 3=9. So, you have 9/8. And when your top number is equal or greater than your bottom number its more than a whole. So, you have 1 1/8. Then you add the 1 to the 3, and you get 4, you have 1/8 left over, so your answer is 4 1/8

Answer:

Answer:

Rate of change is slope

To calculate slope its

y2 - y1 / x2- x1  = slope

Just choose 2 random sets from the table.

I’m gonna go with (0,-10) and (2,20)

Now calculate slope

20 - (-10) / 2 - 0

Solve.

30 / 2

30/2 = 15

Rate of change is 15
