PLEASE HELP ME !!!!!!!!!!
Answer:
x=139
Step-by-step explanation:
since a straight line is equal to 180 degrees line LN is 180 degrees therefore to figure x you must subtract 41 from 180 to get 139 hope this helps! :)
Answer:
z = 139°
Step-by-step explanation:
LON is a straight angle (an angle with 180°). You can tell just by looking at it.
41° is a supplement (meaning it adds up to 180°) of z.
From there you can just do
180° - 41° = 139°
z° = 139°

Answer:
x = [tex]\frac{5}{6}[/tex]
Step-by-step explanation:
→Add 6 to both sides:
12x - 6 =4
12x = 10
→Divide both sides by 12:
x = [tex]\frac{10}{12}[/tex]
→Simplify:
x = [tex]\frac{5}{6}[/tex]

Can someone please tell me what the slope-intercept equation for this graph is!!!! Braniest and Extra points will be given!!!
Answer:
see below
Step-by-step explanation:
The slope-intercept form of a line is y = mx + b where m and b are the slope and y-intercept respectively. From the graph we see that b = 11 (because it is halfway between 10 and 12) and m = 3 (see 2 marked points on the graph). Therefore our answer is y = 3x + 11.

Cindy dissolves 19 1 /4 grams of drink mix in 1 3 /4 ounces of water. What is the unit rate in grams of drink mix per ounce of water?
Answer:
There are 11 g of drink mix for every ounce of water.
Step-by-step explanation:
In order to calculate the unit rate in grams of drink mix for ounces of water of any type of drink, we need to divide the mass of drink mix in grams by the mass of water in ounces. In this case there are mixed fractions, we will first convert them to fractions, to do that we sum the fraction part with the integer one.
[tex]mix = 19 + \frac{1}{4}\\\\mix = \frac{77}{4}[/tex]
[tex]water = 1 + \frac{3}{4}\\\\water = \frac{7}{4}[/tex]
The rate is:
[tex]rate = \frac{mix}{water}\\\\rate = \frac{\frac{77}{4}}{\frac{7}{4}}\\\\rate = \frac{77}{7}\\\\rate = 11[/tex]
There are 11 g of drink mix for every ounce of water.
Answer:
There are 11 g of drink mix for every ounce of water.
The volume of a cylinder is 576, cubic inches. The radius of the circular base is 4 inches. What is the height of the cylinder?
Answer:
36 / pi = h
Using 3.14 for pi
h =11.46496815 inches
Using the pi button
h =11.45691559 inches
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the volume and the radius
576 = pi ( 4)^2 h
576 = pi 16 h
Divide each side by 16 pi
576/16 pi = pi 16 h/ 16 pi
36 / pi = h
Using 3.14 for pi
h =11.46496815 inches
Using the pi button
h =11.45691559 inches

Answer:
3.5
Step-by-step explanation:
Given: x-y=0.7
Finding: 5(x-y)
So we have that x-y=0.7 meaning that for this equation we only need to multiply 5×0.7 which is 3.5
The answer to the expression is 3.5
How to solve the expression?In algebra, we are taught that the two rules for solving equations are the addition rule and the multiplication/division rule.
Given:

Solve the equation x + 7 = 12
Answer:
5
Step-by-step explanation:
x=12-7
x = 5
Answer:
x=5
Step-by-step explanation:
x+7=12
If you do the same thing to both sides of the equation, then the trueness of the equation does not change. Therefore, I can subtract 7 from both sides of the equation to isolate x.
x+7-7=12-7
x=5

Graph the image of the figure after a dilation with a scale factor of 3 centered at (2, −7). Use the Polygon tool to graph the quadrilateral by connecting all its vertices.
Answer:
Here's what I get.
Step-by-step explanation:
Assume the figure is like Image 1 below.
We must dilate each point by a scale factor of 3 centred at (2, −7).
1. Determine the transformation rules
Each point moves to three times its original distance from the centre.
Let P = a point on the figure and
let O = the centre of dilation
and L = the distance from the point to the centre. Then
L = P - O
Three times that distance is
3L = 3P - 3O
We want to find the point P' that is 3L from O, so we add this distance to the coordinates of O.
P' = 3L + O = 3P - 3O + O = 3P + 2O
If P is at (x,y) and O is at (h,k), the transformation rule is
(x,y) ⟶ (3x - 2h, 3y - 2k)
2. Make a table of the new coordinates
[tex]\begin{array}{cclc}\textbf{Point} & \mathbf{(x,y)} &\textbf{Image Coordinates } \mathbf{(3x - 2h, 3y - 2k)}&\mathbf{(x',y')} \\A & (-2,-7) & (-6,-21) -2(2,-7) = (-6 - 4, -21 + 14) & (-10,-7) \\B & (0,-4) & (0,-12) -2(2,-7) = (0 - 4, -12 + 14)& (-4,2) \\C & (3,-3) & (9,-9) -2(2,-7) = (9 - 4, -9 + 14) & (5,5) \\D & (4,-5) & (12,-15) -2(2,-7) = (12 - 4, -15 +14) & (8,-1) \\\end{array}[/tex]
3. Graph the new shape
You should get a graph like Fig. 2.
The rays from Point O pass through corresponding points in the two shapes, so this is a dilation about O.
Point B is two units left of O and three units up.
Also, B' is six units left and nine units up, so the scale factor is three.
Which one is greater 1 4/5 or 21/12
Answer:
I think 21/12
Step-by-step explanation:
hope it works out,!!
Answer:
Here is the answer 21/12
Step-by-step explanation:
to break 21/12 into a fraction we need to subtract, add a whole.
21-12 is 9 1 9/12
now we need to find a gcf for only 9/12 but divide
this is because the gcf of 4/5 is only 1 so we can’t use it
the gcf for 9/12 is 3
9/12 divided by 3 is 3/4
to know what’s greater I use the butterfly trick Which is sideways multiplying
3. 4
- -
4 5
3 x 5 is 15
4 times 4 is 16
below the 16 should be 4/5
and if you look all the way at the top, it started as 21/12
so it is 21/12

he center is consideirng signing up for an online game-rental service rather than buying the games. The table shows equipment cost and monthly fees for two services.
Equipment cost mouthy cost
Net games 99$ 8$
Equipment cost mouthy fee
anytime games 19$ 19$
1. Write and solve an inequality that represents the number of months the center could rent games from NetGames with its $175. Explain the solution in terms of the problem.
2. Write and solve an inequality to represent the number of months the center could rent games from Anytime Games. Explain the solution in terms of the problem.
3. Use your answers from 1 and 2 to justify which service the community center should purchase.
Answer:
see below
Step-by-step explanation:
From Netgames
175≥ 99 + 8x
Subtract 99 from each side
175-99 ≥ 99-99 + 8x
76≥ 8x
Divide each side by 8
76/8 ≥ 8x/8
9.5≥ x
He can get up to 9 months along with the equipment
From Anytime
175≥ 19 + 19x
Subtract 19from each side
175-19 ≥ 19-19 + 19x
156≥ 19x
Divide each side by 19
156/19 ≥ 19x/19
8.210526316≥ x
He can get up to 8 months along with the equipment
Since he can get more months from Netgames, he should rent from netgames
Answer:
The center should rent from Net games
Step-by-step explanation:
1. Net games:
175 ≥ 99 + 8x
175 - 99 ≥ 8x
76 ≥ 8x
9.5 ≥ x
It can rent games for 9 and a half months
2. anytime games:
175 ≥ 19 + 19x
156 ≥ 19x
8.2 ≥ x
It can rent games for 8 months
3. Since the center can rent games for a longer period of time with Net games (9.5 months compared to anytime's 8 months), it should rent from there.
Hope this helps, and please mark me brainliest if it does!
