Answer:

-12

Step-by-step explanation:

-12=-4^2- -4

Answer:

20

Step-by-step explanation:

I put it into a graphing calculator

and If u put -4 in for x u get:

-4^2= 16

g(-4)= 16 - (-4)

g(-4)= 20 bc 16 minus a negative 4 is a positive 20

hope this helps <3

Answer:

422[tex]cm^2[/tex]

Step-by-step explanation:

1. Approach

This problem asks one to find the surface area of the given figure. This can be done by splitting the given figure into two similar figures. Then calculate the surface area of each of the similar figures. After doing so, subtract the covered surface areas, the contact point between the two simple figures is not a part of the surface area since it is covered by the other part of the figure. Remember to take away twice the area of this contact point, since it is present on both figures.

2.Find the surface area of the first figure

The surface area of a figure is the two-dimensional space around the figure. In essence, if one were to wrap the figure in paper, the surface area is the amount of paper one would need. Find the 2-dimensional area of each side, this can be done by multiplying all combinations of two dimensions together, adding the results, and then multiplying that value by (2).

(5) * (10) = (50)

(5) * (7) = (35)

(7) * (10) = (70)

Now add thee value together,

(50) + (35) + (70)

= (155)

Double the result,

(155) * (2) = (310)

3. Find the surface area of the other figure

Now repeat the process that was used to find the surface area of the other figure for this figure.

(8) * (4) = (32)

(4) * (3) = (12)

(8) * (3) = (24)

Add the results,

(32) + (12) + (24) = (68)

Double the value,

(68) * (2) = (136)

3. Now subtract the repeated side

Now that one has the value of both simple figures, add up the value and then subtract twice the value of the repeated side.

(310) + (136) = (446)

(446) - ((2)*(4)*(3))

= (446) - (24)

= (422)

Answer: can't add an answer, but for the first all 3 angles add up to 180 in a triangle for the second, plug 5 in and also check if all three add up to 180

Answer:

I might be wrong but I did the calculations and my answer is that she put $30 aside each week and the airfare to hawaii is $660

Step-by-step explanation:

This is how I find my answer

first:

14 weeks - 9 weeks = 5 weeks

$390 - $240 = $150

$150/5 = $30 ( that is what she save per week)

then I did

$30 x 140 = 420 + 240 = $660

The constant - or b, in the equation y = mx+b - is the y-intercept.

Then just increase your points by m, the slope, for every one unit. ex: if m = 5, then when you move right one unit, move up 5 unites

Answer:

system of equations

Step-by-step explanation:

x-y=14

x = 2y+3

x - y = 14

x -2y = 3

x - y = 14

-x + 2y = -3

y = 11

x = 25

First of all look at the picture it will help.

2nd of all rhombuses are always Perpendicular when you Bisect them.

Answer:

A. 38 degrees

Step-by-step explanation:

That entire angle is supplementary meaning it will add up to 180 degrees. So we are given 52 and 90 because of the right angle. Those together come to 142 then subtract that from 180 and get 38 degrees.

Answer:

Average size of the lots = ⅓ acre

Step-by-step explanation:

The question incomplete without specifying what we are to determine.

Question:A builder is buying property where she can build new houses. The line plot shows the sizes for each house. 1/6 has 6 X's 1/3 has 3 X's and 1/2 has 6 X's. Organize the information in a line plot. What is the average size of the lots? _________ acre

Help anyone?

Solution:

We are asked to organize the information in a line plot. See attachment for the line plot.

Given: 1/6 has 6 X's 1/3 has 3 X's and 1/2 has 6 X'sIn no particular order, the sizes of the lots are:1/6, 1/6, 1/6, 1/6, 1/6, 1/6, 1/3, 1/3, 1/3, 1/2, 1/2, 1/2, 1/2, 1/2 and 1/2 acre.

Let's count the number of lot for each size given.

For 1/6: there are 6 X's on the line plot of 1/6 number of lot for 1/6

= the lot × number of times it occurs

= (1/6) × 6 = 6/6 = 1 acre

For 1/3: there are 3 X's on the line plot of 1/3 number of lot for 1/3 = the lot × number of times it occurs

= (1/3) × 3 = 3/3 = 1 acre

For 1/2: there are 6 X's on the line plot of 1/2 number of lot for 1/2

= the lot × number of times it occurs

= (1/2) × 6 = 6/2= 3 acres

To find average size of the lots, we would sum all lot for each given size then divide by the total number of lots given.Sum of all lot for each given size = 1+1+3

Sum of all lot for each given size = 5

The total number of lots given = 15

Average size of the lots = 5/15 = 1/3

Average size of the lots = ⅓ acre
