Answer:

3/1

Step-by-step explanation:

you need to count the hight of the line from the (0,2) which will be 3 and then how much of the distance of x is. I used rise over run.

Answer:

the value of the h is 6

Step-by-step explanation:

6 x 7 = 42

Answer: 2cm/year

Step-by-step explanation:

1m = 100cm

200m = 20000cm

10,000years = 20,000cm

1 year = 20,000/10,000 = 2cm

It's rate is 2cm/year

Answer:

0.02 cm/year

Step-by-step explanation:

200m:10,000 years

10,000 divided by 10,000=1

200 divided by 10,000=0.02

0.02m : 1 year

Answer:

18c - 30d + 36

Step-by-step explanation:

Answer: Each shelf is 2ft

Step-by-step explanation:

16 = (2 x 4) + 4s

16 = 8 + 4s

8 = 4s (subtract 8 from both sides)

8/4 = 4s/4 (divide both sides by 4)

2 = s

Answer:

2 feet, 2.3 feet, 2.25 feet, and 16 feet

Answer:

[tex] slope (m) = -5 [/tex]

Step-by-step explanation:

The slope can be calculated using two points, (2, 60) and (4, 50) as shown below:

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex], where,

[tex] (2, 60) = (x_1, y_1) [/tex]

[tex] (4, 50) = (x_2, y_2) [/tex]

Plug in the values into the equation

[tex] slope (m) = \frac{50 - 60}{4 - 2} [/tex]

[tex] slope (m) = \frac{-10}{2} [/tex]

[tex] slope (m) = -5 [/tex]

x=6

Step-by-step explanation:

Answer:

Total cost= $12,300

Step-by-step explanation:

Giving the following information:

Fixed cost= $1,500

Monthly cost= $450

To calculate the total cost, we need to use the following formula:

Total cost= fixed cost + unitary variable cost*x

x= number of units

For 2 years:

Total cost= 1,500 + 450*24

Total cost= $12,300

Answer:

Step-by-step explanation:

Answer:

x=58

Step-by-step explanation:

ok this is a 5 sided polygon

5 sided polygon has 540 degrees

540-90-120-108-100= the unkown angle

122

but look at the line exterior plus interior = 180 degrees

180=122+x

subtract 122 from both sides

x=58

Answer:

  89.1 liters

Step-by-step explanation:

"At the same rate" means miles and liters are proportional. The unknown is liters, so we can write the proportion with liters in the numerator:

  liters/miles = x/672 = 49/369.6

Multiplying by 672, we have ...

  x = 672(49/369.6) ≈ 89.09091

It will take 89.1 liters of gas to go 672 miles.

Answer:

60 would be a good inverse for this table, it is best for xy, 60 is the k/p in this equation.

Step-by-step explanation:

Answer:

1.5

Step-by-step explanation:

The formula for inverse variation is xy=k. So i did 3*5 which is 15 and then I did 15*1 which is 15 and 30*0.5 which is 15. So know i know that 10 times something has to equal 15 so i do 15/10 to get 1.5 which is my answer

Answer:

The value of AC = 5 units

Step-by-step explanation:

Given the triangles

In the diagram,

We know that two triangles are termed as similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Therefore,

AB : XY = AC : XZ

AB / XY  = AC / XZ

as

so we can determine AC as the ratios of the side become

4 / 6  = AC / 7.5

AC = 4/6 × 7.5

      = 5 units

Therefore, the value of AC = 5 units

Answer:

17550 solutions

Step-by-step explanation:

Given that:

y1 +y2+y3+y4=27

where;

(yi  ≥ 0 and yi [tex]\epsilon[/tex] [tex]{\displaystyle \mathbb {Z} }[/tex]  )

The no. of a nonnegative integer determines the number of ways to choose 27 objects from (4) distinct objects with repetition regardless of the order.

i.e

[tex]\bigg(^{27}_{4} \bigg)[/tex]

∴

The number of nonnegative integer solution is [tex]\bigg(^{27}_{4} \bigg)[/tex]

[tex]= \dfrac{27!}{4!(27-4)!}[/tex]

[tex]= \dfrac{27!}{4!(23)!}[/tex]

[tex]= \dfrac{27\times 26\times 25\times 24 \times 23 !}{4\times 3\times 2\times 1(23)!}[/tex]

[tex]= \dfrac{27\times 26\times 25\times 24 }{4\times 3\times 2\times 1}[/tex]

[tex]= \dfrac{421200}{24}[/tex]

= 17550 solutions

Answer:

Part A: C

Part B: B

Part C: 15.91

Step-by-step explanation:

first round the 2 numbers by the tenths. Then round the numbers by ones(whohle number). After that, since ther are four sides we do 12.63 + 3.28 + 12.63 + 3.28 which equals to 15.91.

If xy = 1, then differentiating both sides with respect to x gives

x dy/dx + y = 0

(use the product rule)

Solve for dy/dx :

dy/dx = -y/x

Solve the starting equation for y and substitute that into the derivative.

xy = 1   →   y = 1/x

→   dy/dx = -(1/x)/x = -1/x²

Answer:

P(-2,4)

Q(2,5)

R(-1,8)

Step-by-step explanation:

The rule for reflecting points across the x-axis is to keep the x-value the same but "negate" the y-value. So, the points above are your answers.

Answer:

The answer is: 37

Step-by-step explanation:

The reason its this answer because first thing you have to do is the order operations Please Excuse My Dear Aunt Sally, since there is no parenthesis, or exponents we cross those out. Since, there is multiply we put in -14 where is x.

-3x-5=-3(-14)=5

Next, we multiply -3 and -14 and we get:

42, there reason its not a negative because two negatives equal to a positive.

There is Division or Addition, those are out. The only thing that is left Subtraction... So we are going to subtract 42-5 which equals;

37

Step-by-step explanation:

Answer:

nearest tenth is 23.5

nearest hundredth is 23.55

Step-by-step explanation:any number more than 5 is rounded up to +1 for the next number so for tenth 23.546= 23.5 and for hundredth 23.546=23.55
