Last month, Jennifer weighed 150 pounds. Thismorning, her weighing scale showed her weight changed by 10 percent as compared to last month. Selectall the possible weight reflected on the weighing scale.
Answer:
165
Step-by-step explanation:
150(1.1)=165
Answer:
165 pounds
Step-by-step explanation:
[tex]\frac{10}{100} =\frac{y}{150}[/tex]
100 × y = 10 × 150
100y = 1500
100y ÷ 100 = 1500 ÷ 100
y = 15
150 + 15
165

1. Solve for x: 2x + 8 = 180
x=
2.Solve for x: 3x - 3 = 90
x=
3.Solve for x: 2x - 5 + x - 7 = 180
x=
4.Solve for x: x + 1 + x + 4 + x - 2 = 90
x=
Answer:
1. x = 86
2. x = 31
3. x = 64
4. x = 29
Step-by-step explanation:
1. 2x + 8 = 180
-8 -8
2x = 180 (divide both sides by 2 to get x by itself)
2. 3x - 3 = 90
+ 3 +3
3x = 93 (divide both sides by 3 to get x by itself. you divide because 3x is multiplying and you have to do the reverse operation)
3. 2x -5 + x - 7 = 180 (you combine like-terms)
3x -12 = 180
+12 +12
3x = 192 (you divide by 3 on both sides)
4. x + 1 + x + 4 + x - 2 = 90 (combine like-terms)
3x + 3 = 90
-3 -3
3x = 87 (divide both sides by 3)
Answer:
1) 2x + 8 = 180
Take 8 to the right side.
2x = 172
Divide both sides by 2.
x = 86
2) 3x - 3 = 90
Take -3 to the right side.
3x = 93
Divide both sides by 3.
x = 31
3) 2x - 5 + x - 7 = 180
Combine like terms.
3x - 12 = 180
Take -12 to right side.
3x = 192
Divide both sides by 3.
x = 64
4) x + 1 + x + 4 + x - 2 = 90
Combine like terms
3x + 3 = 90
Take 3 to right side.
3x = 87
Divide both sides by 3.
x = 29

What is the value of the expression below when x=8 and y=4
9x-2y
Answer 64
Step-by-step explanation: if x is 8 you do 8 x 9 which is 72. Then you do 2 x 4 which is 8. So now you have 72 - 8 which is 64.

Factor the quadratic x2+ 3x − 10. Explain your process for factoring and rewrite the original quadratic in factored form
Answer:
(x-2)(x+5)
Step-by-step explanation:
when factoring, our equation should be in this format: (x+__) (x+__) Then we have to find numbers that add up to 3 but multiply to -10 aka -2 and 5. -2+5=3 and -2(5)= -10

Use the following image to complete the sentences describing the ratio of big fish to small fish.
10 and 5
vyvhiknvcrfyijuedguiin
There are 8 big fish for every 10 small fish, There are 4 big fish for every 5 small fish.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
We need to find the number of small fishes for 4 big fish.
We can see that the big fish and small fish numbers are in proportion to each other.
Assume the small fish corresponding to 4 big fish be 'x'.
Therefore, using the proportion of two quantities, we have;
[tex]\dfrac{8}{10}=\dfrac{4}{x}[/tex]
Now on cross multiplying we get:
8x = 4×10
8x =40
Dividing both sides by 8, we get:
x=5
Hence, there are 4 big fish for every 5 small fish.

How do I divide fractions by whole numbers?
Multiply the denominator of a fraction by a whole number and after you have done that, simplify the fraction as sometimes needed.
You might want to watch a helpful video that will explain examples of how to do that if this doesn't help.

Find the volume of the prism.
H-8cm L-12cm W-6cm
Answer:
Step-by-step explanation:
Let’s break this apart.
Box= 12cm x 8cm x 6cm
Cube= 2cm x 2cm x 2cm
How many cubes fit in the box?
calculate the volume of the box. To do this, multiply the length by the width by the height (L x W x H)
12 x 8 x 6 = 576cm cubed
2. Calculate the volume of the cube. Once again we multiply L x W x H
2 x 2 x 2 = 8cm cubed
3. Next we divide the volume of the box by the volume of the cube
576 / 8 = 72 cubes
Therefore, it would take 72 cubes to fill a box.

Answer:
Step-by-step explanation:
SO LETS FIND THE AREA OF THE SQUARE ( THE BASE )
8 x 8 = 64
so we have 64
SO LETS FIND THE AREA OF THE TRIANGLE ( THE LATERAL AREA )
area = (1/2) · b · h
(1/2) x 8 x 9
1/2 x 72 = 36
SO THERE ARE FOUR TRIANGLES
36 x 4 = 144
SO 144 + 64 = 208 SO THE ANSWER IS 208 :)

Answer:
The volume of the ring is 12.6 [tex]cm^{3}[/tex]
Step-by-step explanation:
The volume of the ring will be equal to the increase in the volume after the ring is dropped. In order to find by how much volume increased we just subtract the volume before the ring was dropped from the volume that was recorded after the ring was dropped, and so we get...
(9.2 x 7 x 4.5) - (8.8 x 7 x 4.5) = 289.8 - 277.2 = 12.6 [tex]cm^{3}[/tex]
This figure has an area of____in^2
--Answer--
[tex]5\sqrt{2}[/tex] or 7.0710... (7.1)
--Explanation--
If you look closely the triangle on the left could be moved to the space on the right of the shape.
Then, the edges would be 10 inches (top) and 5 inches (sides).
From there, you multiply 10 x 5 to get 50. If you want the square root, you do [tex]\sqrt{50}[/tex] which is how I got 7.071067812, or 7.1, which was rounded to the nearest tenth.
