Answer:

 5<k  

Step-by-step explanation:

Answer:

k-5

Step-by-step explanation:

So, lets go over each part of the sentence, and turn it into a expression.

So it first says sum. This means addition, so we can start our expression with:

+

Next is says of 5. So we know its the addition of 5:

+5

Next it says less than. So now we know less than, which is subtraction. So we can swap the addition sign for a - sign:

-5

Finally it says the number k. So we know that the subtracted value is k:

k-5

So this is your expression!

Hope this helps!

Answer:

n+2 is the next even number as n is an even number so adding 2 will make it an even number again.

Answer:

y=5x-8 is the parallel line that passes through the point (3,7)

Step-by-step explanation:

Find the slope of the original line and use the point-slope formula y-y₁=m(x-x₁) to find the parallel line to y=5x-21, which if done correctly you should end up with y=5x-8

Answer:

The second option

Step-by-step explanation:

To solve this, you should convert both rates to equations, with y being the total fare, and x being the number of miles. The rates of both use the format y=mx+b (where m is the amount per mile and b is the flat rate, or original rate).

By subbing in the values for m and b, you get y=2x+4 for A and y=3x+5 for B. This is the second option.

Answer:

Given that 3/7 + (- 6/11) + (- 8/21) + (5/22)

Taking L.C.M. of the denominators 7, 11, 21 and 22 and then solving it.

L.C.M. of 7, 11, 21 and 22 = 2 x 3 x 7 x 11 = 462

= (462/7) x 3 – (462/11) x 6 – (462/21) x 8 + (462/22) x 5

= (198/462) – (252/462) – (176/462) + (105/462)

Answer:

A. 25/33

B. 1/3

C. 1/33

D. 25/9

Answer:

[tex]\text{A. }25/33,\\\text{B. }1/3, \\\text{C. }1/33, \\\text{D. }25/9[/tex]

Step-by-step explanation:

Recall that [tex]\frac{x}{9}=0.\overline{x}[/tex] for [tex]x\in (1, 8)[/tex]. If multiple digits are repeating, increase the number of nines in the denominator as applicable.

Therefore, we have:

Part A:

"75" is repeating:

[tex]\rightarrow \frac{75}{99}=\boxed{\frac{25}{33}}[/tex]

Part B:

"3" is repeating:

[tex]\rightarrow \frac{3}{9}=\boxed{\frac{1}{3}}[/tex]

Part C:

"03" is repeating:

[tex]\rightarrow \frac{03}{99}=\frac{3}{99}=\boxed{\frac{1}{33}}[/tex]

Part D:

"7" is repeating, but there is a terminating decimal 2.0 with it ([tex]2.\overline{7}=2.0+0.\overline{7}[/tex]):

[tex]2+\frac{7}{9}=\frac{18}{9}+\frac{7}{9}=\boxed{\frac{25}{9}}[/tex]

Answer:

Step-by-step explanation:

[tex]F = \frac{9}{5}C+32[/tex]

Subtract 32 from both sides

[tex]F-32= \frac{9}{5}C\\[/tex]

Multiply both side by 5/9

[tex]\frac{5}{9}(F-32)=( \frac{5}{9})* \frac{9}{5}C\\\\ \frac{5}{9}(F-32)=C\\[/tex]

F= 41

[tex]\frac{5(41-32)}{9}=C\\\\ \frac{5*9}{9}=C\\\\ \frac{45}{9}=C\\\\C = 5\\\\[/tex]

Check explanation

Step-by-step explanation:

Given:

y = -0.1x + 22

Where,

y = BMI of an individual

x = antioxidant food consumption per day in cups

Equation of a slope

y = mx + c

Where,

m = slope

c = y - intercept

Therefore,

From the equation

y = -0.1x + 22

slope, m = -0.1

y - intercept, c = 22

Answer:

The y-intercept tells us that a person who doesn’t have any antioxidant foods can expect to have a BMI of 26. For every cup of antioxidant food that is consumed one can expect to lower their BMI by 1.2.

Answer:

[tex]Average = 38[/tex]

Step-by-step explanation:

Given

The attached histogram

Required

The average work hours by 20 salespeople

First, we get the total hours worked as follows:

[tex]Hours = 3 * 30 + 5 * 34 + 9 * 40 + 2 * 45 + 1 * 50[/tex]

[tex]Hours = 760[/tex]

Divide by number of salespeople

[tex]Average = Hours/n[/tex]

[tex]Average = 760/20[/tex]

[tex]Average = 38[/tex]

Step-by-step explanation:

the answer is in the above image

The distance between point A and point B is 10 units.

The distance between two points on a coordinate plane (x, y) and (x, y) is

= √[(x₂ - x₁)² + (y₂ - y₁)²] units

The given straight line is 3x + 4y = 24.

This straight line will cut the x-axis at a point where y = 0.

Therefore, 3x + 4(0) = 24

⇒ 3x = 24

⇒ x = 8

Therefore, the coordinates of the point A is (8, 0).

Similarly, this straight line will cut the y-axis at a point where x = 0.

Therefore, 3(0) + 4y = 24

⇒ 4y = 24

⇒ y = 6

Therefore, the coordinates of the point B is (0, 6).

Therefore, the distance between point A and point B is

= √[(0 - 8)² + (6 - 0)²] units

= √(64 + 36) units

= √100 units

= 10 units   (negative sign is avoided.)

Answer:

24 squared ft.

Step-by-step explanation:

Area of a triangle is 1/2(b*h)

b=8 ft, c=6 ft

Therefore, area

= 1/2(8*6)

= 1/2(48)

= 24 square ft

Answer:

(0, -5)

Step-by-step explanation:

Multiply both sides of the second equation by 6 to get 6y=3x+30. Then, subtract the second equation from the first to cancel out the x's. y-6y=-5y, 3x-5-3x-30=-25. -5y=-25, so y=-5. Substitute -5 into the first equation to get 3x-5=-5, add five to both sides: 3x=0, divide by 3: x=0. The ordered pair is (0, -5). Hope this is correct and helps! :)

Half the numbers on the die are even so you have a 1/2 probability of getting an even number. There is also. 1/2 probability of getting heads on a coin flip.

To find the probability of both happening, multiply the probability of each together:
