Which equation represents a function?

Answer:

118.9

Step-by-step explanation:

145 x 0.82

= 118.9

Answer:

3 29/40 kg

Step-by-step explanation:

An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms. LaTeX: \frac{3}{4}3 4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh? Enter your number as a mixed number. (no decimals)

Step 1

We find the fraction of the sculpture that is wood

Let the Fraction of the sculpture = 1

Fraction of the sculpture that is metal = 3/4

Fraction of the sculpture that is wood =

1 - 3/4

= 1/4

Step 2

How much does the wood part of the sculpture weigh? Enter your number as a mixed number. (no decimals)

This is calculated as:

Weight of the total sculpture × Fraction of the sculpture that is wood

= 14.9 kg × 1/4

= 3 29/40 kg

Answer:

b = 0.938

Step-by-step explanation:

Value of the car can be modeled by the function,

V(t) = [tex]45000(b)^t[/tex]

Since, formula for the depreciation is modeled by,

V(t) = [tex]V_0(1-\frac{r}{100})^t[/tex]

Here, V(t) = Final value of the car after t years

V(0) = Initial value of the car

r = rate of depreciation

t = Time (in years)

By comparing both the functions which are similar,

[tex]1-\frac{r}{100}=b[/tex]

[tex]1-\frac{6.2}{100}=b[/tex]

b = 1 - 0.062

b = 0.938

Answer:

15 shirts per hour

Step-by-step explanation:

There are 3 20 minutes in an hour so you would do 5 x 3, which is 15. I hope this helps!

If you need me to furtherly explain let me know

If correct please mark brainliest

Answer:

Step-by-step explanation:

The answer would be 15 shirts per hour since 20 minutes is one third of an hour which mean you can multiply 20 three times to get an hour ( 60 minutes) and since you multiplied 20 you also have to multiply five which gives you 15 shirts per hour

I=prt

1200=960*x*5

1200=4800x

divide both sides by 4800

x=0.25

Answer:

The angles are adjacent. x = 100°

Step-by-step explanation:

x + 80 = 180

x = 100

Answer:

y= x+ 4

Step-by-step explanation:

use y= mx+b where m is the slope and y is the y intercept

in this case the slope is one and y intercept is four

Answer:

6,700 because 6 is in the hundreds place and 6 is more then 5 so u go up and since it's to hundreds the answer is 6,700

Step-by-step explanation:

Answer:

Step-by-step explanation:

Simplifying

10 = 4y

Solving

10 = 4y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-4y' to each side of the equation.

10 + -4y = 4y + -4y

Combine like terms: 4y + -4y = 0

10 + -4y = 0

Add '-10' to each side of the equation.

10 + -10 + -4y = 0 + -10

Combine like terms: 10 + -10 = 0

0 + -4y = 0 + -10

-4y = 0 + -10

Combine like terms: 0 + -10 = -10

-4y = -10

Divide each side by '-4'.

y = 2.5

Simplifying

y = 2.5

Answer:

every 24, there is 3 (let's assume)

Answer:

  a) turning point: (-2, -1)

  b) roots: (-3, 0), (-1, 0)

Step-by-step explanation:

The turning point is correctly identified as the vertex in the problem picture.

The roots are the x-intercept points: (-3, 0) and (-1, 0).

Answer:

x = 2

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

45 + 25x = 65 + 15x

25x - 15x = 65 - 45

10x = 20

x = 2

Step-by-step explanation:

[tex] \sqrt{(60 \div 10) {}^{2} } \\ = \sqrt{(6) {}^{2} } \\ = \sqrt{36 } \\ = 6[/tex]

6 is your answer

Answer:

[tex]\sqrt{\left(\frac{60}{10}\right)^2}[/tex]

[tex]\sqrt{\left(\frac{60}{10}\right)^2}=\frac{60}{10}[/tex]

Answer:

1. (4,2)

2. No solution

3. (1,3)

Answer: -1

Step-by-step explanation:

Answer:

A. Y-68=-5(x-14)

Step-by-step explanation:

Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number of days that have passed. write an equation for the situation

We find the equation using the point slope equation of a line. This is given as:

y - y1 = m(x-x1)

The slope intercept form will be

y = -5x + b

since the amount decreases by $5 per day...

Our slope is -5 so m=-5

We have a point (x1,y1) = (14, 68)

Hence, we have:

y-68 = -5(x-14)

Option A is correct
