x=30

Hope it helps!

Mark as brainliest please!

Answer:

Step-by-step explanation:

Given proportion,

→ 21/35 = 18/x

Now we have to,

→ Find the required value of x.

Let's find the value of x,

→ 21/35 = 18/x

→ 21x = 18 × 35

→ 21x = 630

→ x = 630/21

→ [ x = 30 ]

Hence, the value of x is 30.

Answer:

To add 232 and 578, Zoey should start by placing the smaller addend, which is 232, on the number line. She can then add the larger addend, which is 578, by counting up from 232.

Here's how Zoey can do it:

Therefore, Zoey should place 232 on the number line to start adding 232 and 578.

Zoey should place the addend 232 on the number line to start.

A number line is a straight line drawn horizontally where the numbers are placed at an equal intervals.

Number line has numbers 232 and 578 marked at different points.

In order to find the sum of these two addends, we have to place the smaller addend at the start.

Here 232 is the smaller addend

578 is the larger addend.

Start with the smaller one, 232.

Then add the larger addend to it.

Hence the addend that should be started with is 232.

Answer:

  B.  380 square centimeters

Step-by-step explanation:

A triangular prism has triangular bases. The lateral surface area is the total area of the three rectangular faces that are not the bases.

__

The lateral surface area can be found by multiplying the perimeter of the base by the height of the prism (the distance between bases).

The perimeter is the sum of the lengths of the edges of the base:

  P = 8 cm + 6 cm + 5 cm = 19 cm

The distance between the bases is 20 cm, so the lateral surface area is ...

  LA = Ph = (19 cm)(20 cm) = 380 cm²

The lateral surface area is 380 square centimeters.

Answer:

p = 12.20h

30.5 hours

Step-by-step explanation:

Jackson works as a veterinary technician and earns per hour = $12.2

He works in a normal week = 40 hours

Let hours = h and weekly pay = p

p = 12.20h

p = $12.20 × 40

= $488.00

Last week Jackson was ill and missed some work.

 His total pay before deduction was $372.10

To find the hours he work the equation will be p = 12.20h

372.10 = 12.20h

372.10/12.20 = h

h= 30.5

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer:

-2 is y-intercept

Step-by-step explanation:

If a linear function passes through the points (10,5) and (-15,-5), then the slope of it must be 2/5.

This is because the formula to find slope is  (y2-y1 / x2-x1), which in this case, when the values are input, equal to 2/5.

When finding the slope of 4x-3y=6, we need to rewrite the equation in slope-intercept form, causing the original equation to become y=4/3x-2. In this case, 4/3x symbolizes the slope (4/3).

Seeing as 4/3 > 2/5, we will consider the y-intercept of 4x-3y=6 as the correct answer.

Subsitute x for 0:

4(0)-3y=6

= -3y=6

Divide both sides by -3:

-3y/3 = 6/-3

= (y = -2)

Therefore, the correct answer is -2, the y-intercept of the equation 4x-3y=6.

Answer:

B)  60%

Step-by-step explanation:

Percentage formula

\(\sf Percentage=\left(\dfrac{Value}{Total\:value}\right) \times 100\)

To find what percent of 200 is 120, substitute the values into the percentage formula:

\(\begin{aligned}\implies \sf Percentage & = \dfrac{120}{200} \times 100\\\\&=\dfrac{120 \times 100}{200}\\\\&=\dfrac{12000}{200}\\\\&=\dfrac{120}{2}\\\\&=60\%\end{aligned}\)

Therefore, 120 is 60% of 200.

Answer:

The number of monthly calls for which Plan 1 is more economical than Plan 2 is 200 calls If more than 200 calls are made, the plan 1 charge will be more than plan 2. Let the number of charges per month be x  If plan 2 charges ​$16 per month plus ​$0.04 per call, this is expressed as 0.04x + 16  Price that pan 1 charges = $24  If Plan 1 is more economical than Plan 2, this is expressed as:0.04x + 16 > 24 Subtract 16 from both sides:0.04x + 16 - 16 > 24 - 16   0.04x > 8 x = 6/0.04 x = 200 This shows that if more than 200 calls are made, the plan 1 charge will be more than plan 2.

Hello there!

First things first, place the 2 on the y-axis. 2 is your "y" intercept.

Rule of thumb:  if there is a constant(single number) alone and without any variable next to it, it's going to be your y-intercept.

Next we need to count up three units from the y-intercept and over four units.

Overall:

The 2 should be plotted on the y-axis.

The new coordinate should be (5,4)
