Answer:

Step-by-step explanation:

first, do the question in parenthesis

then do the questions in the exponent

then do the question with division

then do addition part

(7-4)^2 = (3)^2

9/3 = 3

9+3 = 12

The answer would be 6. When you do the parentheses, it gives you 3. 3 squared is 9, which added with 9 is 18. 18 divided by 3 is 6.

I need help plzzzzzzzzzzzzzzzzzzzzzzzz

We can find the value of x through a proportion. Since these two triangles are similar, their sides are in proportion.

4 is to 12 as 5 is to x
Remember to say 12, not 8! 8 is only part of the whole side. We can also simplify 4 is to 12 to 1 is to 3.

1/3 = 5/x
Cross multiply
x = 15
Hope this helps!

The fountain in the pond behind Kevins school has a pump that recirculates 60 gallons of water every 1/5 of an hour.Express this

Rufina [12.5K]

The necessary information's are already given in the question. Based on those information's the answer to the question can be easily determined.
Amount of water recirculated by the pump in 1/5 of an hour = 60 gallons
we already know
1/5 of an hour = (1/5) * 60 minutes
   = 12 minutes
Then
Amount of water recirculated by
the pump in 60 minutes = (60/12) * 60 gallons
   = 5 * 60 gallons
   = 300 gallons
So the amount of water recirculated by the pump per hour is 300 gallons.

Answer:

$78

Step-by-step explanation:

Mark would have $78 in his account. This is because 168-94=92. Then 92+56=148. finally, 148-70= 78. So he has $78.

Find the equations of the line that:

ohaa [14]

Answer: Part A: y = x + 6

Part B: y = 10

The attachment shows the graphs of these equations.

Step-by-step explanation:

Find the slope, and then the y-intercept. Then write the equation in Slope-intercept form . y= mx+b

m is the slope. b is the constant, the y-intercept.

First find the slope: rise/run

Rise is the difference in y-values 10-7 = 3

Run is the difference between x-values 4 - 1 = 3

The Slope is 3/3 simplify:

m = 1

Use this calculated slope with values of y and x from either of the given coordinates and calculate b

y = mx + b

10 = 1(4) + b <em>The 1 is not necessary, its "implied" and invisible as a factor in multiplication</em>

10 = 4 + b . subtract 4 from both sides 10 - 4 = 4 - 4 + b

6 = b

Put these calculated values for m and b into the slope-intercept equation"

y = x + 6

_________

Part B: Step-by-step explanation: Slope-intercept form . y= mx+b

First find the slope: rise/run

Rise is the difference in y-values 10 - 10 = 0

At this point you know that if the slope is 0, it is a horizontal line intersecting the y-axis at the y-value, 10

That graphed line will pass through All x-values.
