Samantha and Mia each left Julia’s house at the same time. Mia walked north at 7 kilometers per hour. Samantha ran west at 11 kilometers per hour. How far apart were they after one hour? Round the answer to the nearest tenth.
Answers
Samantha walked 11km/h so after 1 hour, she is 11 km west of the house of Julia.
The points where Mia and Samantha are after 1 hour , and the house of Julia form a right triangle with sides 7 and 11 km. The distance between the girls, is the hypotenuse of his triangle.
by the pythagorean theorem:
[tex]MS= \sqrt{ 7^{2} + 11^{2} }= \sqrt{49+121}= \sqrt{170}= 13 (km)[/tex]
Answer: 13 km

2 inches 3 inches Pivot. If 60 lbs. of force must be applied to the valve for it to open, how much upward force must push rod X apply for the valve to open?
A 60 lbs
B.40 lbs
C 30 lbs
D.20 lbs
E 15 lbs
Answers
We can solve this problem by stating that the summation of momentums must be zero. That is, the momentum at one end of the pivot must be equal to the momentum at the other end.
Momentum 1 = Momentum 2
Since Momentum is the product of Force and Distance, and with this rule created, we can say that:
F1 * d1 = F2 * d2
Where,
F1 = 60 lbs
d1 = 2 inches from the pivot
F2 = unknown X
d2 = 3 inches from the pivot
Substituting to the equation to find for F2:
60 lbs * 2 inches = F2 * 3 inches
F2 = 40 lbs
Therefore 40 lbs of upward force must be pushed to open the valve.
Answer: B
Final Answer:
40 lbs of upward force must be pushed to open the valve that is option B is correct.

A sporting goods store buys a basketball for $15.00 and then adds a 75% markup to the price. How much will the basketball sell for in the store?
Answers
Turn 25% into a decimal and you would get .25
Then multiply that by 15 and you would get $3.75
$15.00 minus $3.75 you would get $11.25
The basketball would cost $11.25.

What is the length of segment RS
Answers
To find this, you can make a right triangle by connecting points R and S at a common point to form a right angle. The segments made would be 5 units and 12 units long. Using the Pythagorean Theorem, the segment RS must be 13 units.
Answer: 13 units
Step-by-step explanation:
The length of line segment AB with points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)[/tex] is given by distance formula as :
[tex]\text{AB}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Now, the length of line segment RS with points [tex]R(-4,-3)\ and\ S(1,9)[/tex] is given by distance formula as :
[tex]\text{RS}=\sqrt{(1-(-4))^2+(9-(-3))^2}\\\Rightarrow\ RS=\sqrt{(5)^2+(12)^2}\\\Rightarrow\ RS=\sqrt{25+144}=\sqrt{169}\\\Rightarrow\ RS=13[/tex]
Hence, the length of segment RS= 13 units

1. The work of a student to solve the equation 2(3x − 4) = 8 + 2x + 4 is shown below:
Step 1: 2(3x − 4) = 8 + 2x + 4
Step 2: 5x − 6 = 12 + 2x
Step 3: 5x − 2x = 12 + 6
Step 4: 3x = 18
Step 5: x = 6
In which step did the student first make an error and what is the correct step?
Step 2; 6x − 6 = 2(6 + x + 2)
Step 2; 6x − 8 = 12 + 2x
Step 3; 5x − 2x = 12 − 6
Step 3; 5x + 2x = 12 + 6
2. The steps below show the incomplete solution to find the value of m for the equation 4m − 2m + 4 = −1 + 13:
Step 1: 4m − 2m + 4 = −1 + 13
Step 2: 4m − 2m + 4 = 12
Step 3: 2m + 4 = 12
Which of these is most likely the next step?
2m = 3
2m = 8
2m = 16
2m = 18

Triangle with height of 16 inches and base of 14 inches.
Answers
- We know this because...
1. The calculations of a triangle is... 1/2 x b(h)
2. So first, lets calculate the b(h) first, which is 16 x 14 = 224 square inches.
- This isn't the correct answer because it is the area of a rectangle.
3. Second, lets calculate 1/2 x 224 = 112 square inches.
- We did this calculation because we are talking about a triangle.
- So, the total square inches of the club sticker is 112 square inches.

If a person weighs 240 pounds on Earth, what would be the difference in weight of the same person on Mars and on the Moon
Answers
Answer:
Mars: [tex]\Delta W = 144\,lbf[/tex], Moon: [tex]\Delta W = 199.2\,lbf[/tex]
Step-by-step explanation:
The gravitational acceleration experimented by the same person on the Moon is equivalent to a sixth of the indicator on Earth and the same indicator on Mars is about 40 % of the terrestrial acceleration. Then, the difference in weight are computed below:
Mars:
[tex]\Delta W = (1 - 0.4) \cdot (240\,lbf)[/tex]
[tex]\Delta W = 144\,lbf[/tex]
Moon:
[tex]\Delta W = (1 - 0.17) \cdot (240\,lbf)[/tex]

Line CD passes through points (0, 2) and (4, 6). Which equation represents line CD?
y = 2x – 2
y = 2x + 2
y = x + 2

Answers
slope = (6 - 2) / (4 - 0) = 4/4 = 1

use either of ur points (0,2)...x = 0 and y = 2
sub and find b, the y int
2 = 1(0) + b
2 = b
ur equation is : y = x + 2 <==
Answer:
The correct option is 3.
Step-by-step explanation:
If a line passing through two points then the equation of line is
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
It is given that CD passes through points (0, 2) and (4, 6), so the equation of line is
[tex]y-2=\frac{6-2}{4-0}(x-0)[/tex]
[tex]y-2=\frac{4}{4}(x)[/tex]
[tex]y-2=x[/tex]
Add 2 on both the sides.
[tex]y=x+2[/tex]
The equation of line CD is y=x+2. Therefore the correct option is 3.

A rectangle has a perimeter of 84 meters and a length of 35 meters. What is the width of the rectangle?
Answers
Where L is the length and W is the width.
We know the perimeter and we know the length and we want to find the width.
Substitute the values back into the formula.
2(35) + 2W = 84
70 + 2W = 84
2W = 14 <-- Subtract both sides by 70
W = 7 <-- Divide both sides by 2
So, width is 7 meters long.
84 - 70
14 / 2
The width of the rectangle is 7.
Highlighter pens cost $3.86 per set at an office supply store. Which equation can be used to determine the price, P, of n sets of these pens? n = 3.86P P equals 3.86 over n n equals 3.86 over P P = 3.86n
Answers
Meaning N as the number of sets and P as the total price of the # of sets times the unit price.
P=Price
N=Number of pens you buy
The price depends on the number of pens that you buy. Each pen costs $3.86, so you will have to multiply the price of each pen by the number of pens that you buy and it will give you your price to pay.
