Answer:
A
Step-by-step explanation:
5x and 128 are adjacent angles and sum to 180° , then
5x + 128 = 180 ( subtract 128 from both sides )
5x = 52 ( divide both sides by 5 )
x = 10.4 → A
These angles are what we call supplementary angles, which means that the sum of each angle should amount to the measure of a straight angle, 180°
So, we can form an equation.
128+5x=180
Solve using the normal steps.
128-128+5x=180-128
5x=52
x=10.4
Therefore, x=10.4
If you want to check, substitute x in 5x for 10.4.
5(10.4)=52
So, the angles each measure 52° and 128°.
Add them to see if they are 180° together.
52+128=180°
Therefore, x=10.4

Step-by-step explanation:
Find square's area:
A = bh
A = 22 × 22
A = 484
Find equilateral (left hand side) triangle's area:
A = bh/2
A = 22 × 22 / 2
A = 484 / 2
A = 242
Find right (right hand side) triangle's area:
A = bh/2
A = 22 × (38-22) / 2
A = 22 × 16 / 2
A = 352 / 2
A = 176
Add all areas together:
A = 484 + 242 + 176
A = 902
u-5=-8 is tell solution of equation
Answers
Answer:
u = -3
Step-by-step explanation:
Solve for u:
u - 5 = -8
Hint: | Isolate terms with u to the left hand side.
Add 5 to both sides:
u + (5 - 5) = 5 - 8
Hint: | Look for the difference of two identical terms.
5 - 5 = 0:
u = 5 - 8
Hint: | Evaluate 5 - 8.
5 - 8 = -3:
Answer: u = -3
u = -3
step by step
u=-8+5
u =-3

A company has cups for its water cooler. Each cup has a height of 14 cm and the base has a radius of 3 cm. How much water is needed to fill 125 cups
Answers
Answer:
125 cups can hold 49.5 liters of water.
Step-by-step explanation:
The volume of the cup will tell how much water is needed to fill each cup.
The volume of the cup can be determined by the formula
V= base area* height
V= πr²* h
V= 22/7 (3)² (14)
V= 396cm³
125 cups can hold 125 * 396 cm³= 49500cm³
But 1 cm³= 0.001 Liters
Therefore = 49500*0.001= 49.5 liters
125 cups can hold 49.5 liters of water.

Okay, so you can split this thingy up into a rectangle and another rectangle, so that's what we're going to do (see pic below)
So now we take off that 7 from the 13:
13 - 7 = 6
So now we find the area of that little area:
6 x 5 = 30
Now we do the other rectangle:
12 x 7 = 84
Now we add them together:
84 + 30 = 114
So the area of the shape is 114cm²
hope this helps:)

Answers
Answer:

Step-by-step explanation:
To get slope given two points, take the difference of the y values and divide it by the difference of the x values.
(This is also called change in y over change in x, or rise over run)
b-(-2)/2-1=4
b+2/1=4

9 = j
Step-by-step explanation:
12 - j = 3
Adding j to both sides, we get 12 = 3 + j

Plz help I have a geometry exam soon!!!!! :(
Answers
Answer:
a = 93°, b = 120°, c = 150°
Step-by-step explanation:
b + 36 = 78 × 2 => b + 36 = 156 => b = 120°
87 × 2 - b = the minor arc between a and 78
=> 174 - 120 = 54
54 + b + 36 + c = 360
=> 54 + 120 + 36 + c = 360
=> c = 150°
(c + 36) ÷ 2 = a
=> (150 + 36) ÷ 2 = a
=> a = 93°

A dog buried 18 bones in his backyard. On Monday, he dug up 1/2 of his bones. On Tuesday, he dug up another 1/3 of his bones. How many bones are still buried?
Answers
Answer:
3
Step-by-step explanation:
A dog buried 18 bones
On Monday he dug up 1/2 of the bones
On Tuesday he dug up 1/3 of the bones
= 1/2 × 18
= 9
= 1/3×18
= 6
Therefore the remaining bones still buried in the ground can be calculated as follows
= 9+6
= 15
= 18-15
= 3
Hence 3 bones are still buried in the ground

He has a 40% chance of picking blue.
Find 40% of 30.
12
He would draw a blue marble around 12 times.
Answer:
C
Explanation:
So in the bag, there are 10 marbles, and 4 of them are blue, so if he drew from the bag 10 times, we can assume the fraction:
4/10
Next, we see that the denominator, or the number times Cade is drawing from the bag is 30, which makes us multiply most sides of the fraction by 3:
12/30
So I would say 12/30, but again, he wouldn't draw a blue exactly 4 times, and it may be more or less, so either 8/12....
