Joe can run 12 miles in 125 minutes. How many miles can he run in 230 minutes? (solve and explain the steps)
Answer:
Joe will run 22.08 miles in 230 minutes.
Step-by-step explanation:
Given that Joe can run 12 miles in 125 minutes.so Joe running the miles in 1 minute is = 12/125 = 0.096 miles
unit rate = 0.096 miles/per minuteAs Joe runs 0.096 miles in one minute.
Thus, in 230 minutes, Joe will run = 0.096 × 230 = 22.08 miles
Therefore, Joe will run 22.08 miles in 230 minutes.

Which pair of triangles MUST be similar?
A. Triangle 5 has a 25 degree angle and a 75 degree angle. Triangle 6 has a 25 degree angle and a 70 degree angle.
B. Triangles 1 and 2 each have a 40 degree angle.
C. Triangle 7 has a 40 degree angle and a 35 degree angle. Triangle 8 has a 40 degree angle and a 105 degree angle.
D.Triangles 3 and 4 are both scalene. Each have a 65 degree angle.
Answer:
C
Step-by-step explanation:
The total measurement of a triangle is 180
Triangle 7 has a 40 degree angle and 35 degree angle.
40+35=75
180-75=105
Triangle 8 has the same angle that is 40 degrees and 105. And if you do the same math, you would get 35 for the missing angle of triangle 8
Denise bought 116 ounces of beans for a bean dip. She bought both 15-ounce cans and 28-ounce cans, and the total number of cans she bought was 6. Which of these systems of equations can be used to determine the number of 15-ounce cans and the number of 28-ounce cans that she bought? Assume x represents the number of 15-ounce cans and y represents the number of 28-ounce cans.
x + y = 6. 15 x + 28 y = 116.
x + y = 6. 28 x + 15 y = 116.
x + y = 116. 15 x + 28 y = 6.
x + y = 116. 28 x + 15 y = 6.
Mark this and return
Answer:
15x + 28y = 116
x + y = 6

Answer:
61
Step-by-step explanation:
a triangles angles equal 180 so 180-10-19-90 = 61
Answer:
-9
Step-by-step explanation:
Since the opposite angles of both sides are congruent we know that the sides must be congruent also. Therefore, to solve for x we can set them equal to each other.
So the equation will be x+19=10, to solve we must isolate the variable.
First, subtract 19 from both sides
x+19-19=10-19
Then, simplify
x=-9
The average depth of the Artic Ocean is 3.953 x 10^5 feet while the average depth of the Atlantic Ocean is 1.2851 x 10^4 feet. Approximately how many times more deep is the Atlantic Ocean that the Artic Ocean?
Answer:
Hence the artic depth is approximately 31 times deeper than atlantic
Step-by-step explanation:
Given the following;
Average depth of the Artic Ocean = 3.953 x 10^5 feet
Average depth of the Atlantic Ocean = 1.2851 x 10^4 feet.
Taking the ratio of both depth;
Ratio = Depth of Artic/Depth of Atlantic
Ratio = 3.953 x 10^5/1.2851 x 10^4
Ratio = 3.076 * 10^1
Ratio = 30.76
Depth of artic/depth of atlantic = 30.76
Depth of artic = 30.76 * depth of atlantic
Hence the artic depth is approximately 31 times deeper than atlantic

1) The astronaut's sense of imbalance in a space flight is due to the rotation of a device in which he or she feels a fictitious gravity that mimics gravity. The the device rotates according to the mathematical equation: n =g^0.5/2πr^0.5 Where n is the rotational speed and is measured in rotations per second (s). (r) is the radius of the circulator and is measured in meters (m). (g) is a simulation of gravity. Calculate the rotation speed of a device, that has a radius of 1.7 meters and rotates to simulate the gravitational force which equals to: g = 9.8 m/s^2 with steps please
Answer:
n = 0.38 rotation per second
Step-by-step explanation:
The device rotates according to the mathematical equation :
[tex]n=\dfrac{g^{0.5}}{2\pi r^{0.5}}[/tex] ...(1)
Where n is the rotational speed and is measured in rotations per second (s).
r is radius of the circulator and is measured in meters (m).
We need to find the rotational speed when radius is 1.7 m. Put r = 1.7 m in equation (1).
[tex]n=\dfrac{(9.8)^{0.5}}{2\pi \times (1.7)^{0.5}}\\\\=0.38\ \text{rotations per second}[/tex]
Hence, the rotational speed is 0.38 rotation per second.

Question 1 (10 points)

A video game is on sale at Amazon for 30% off the original price of $28.50. Both Pat and Henri want to purchase the game, but they only have $22 each. They each have to pay 10% sales tax. Pat and Henri have different strategies to calculate the price and decide if they have enough money to get the game.
Pat takes 30% of $28.50 and subtracts that from the original price. She takes 10% of the sale price and adds it to the sale price to find the total amount she would have to pay.
Henri finds 70% of the original price and then calculates 110% of the sale price.
Will Pat's strategy calculate the correct total? Explain the calculations.
Will Henri's strategy calculate the correct total? Explain the calculations.
Do they each have enough to purchase the game?

Answer:
Simple!
Step-by-step explanation:
The triangle is obviously a right triangle, meaning, we can use the Pythagorean Theorem to solve for x!
(The Pythagorean Theorem is where [tex]a^2=b^2+c^2[/tex], or the length of the hypotenuse (side opposite to the 90 degree angle) squared is equal to the length of one leg squared plus the other leg squared).
To put it simply:
[tex]x^2=20^2+5^2[/tex]
Now to solve!
[tex]x^2=400+25\\x^2=425\\x=\sqrt{425} \\x=5\sqrt{17}[/tex]
This cannot be simplified further, so that's your answer!

How do I find the measurement indicated in each parallelogram.
Answer:
17) 23
18) 12
Step-by-step explanation:
17
x+15 = 7+2x
x-2x = 7-15
-x= -8
x=8
WX = x+15
= 8+15
= 23
18
2x = 3x-6
2x -3x = -6
-x = -6
x = 6
EF = 3x-6
= 3(6) -6
= 18 -6
= 12

( , )
Answer:
y=17/5 ,x= 38
Step-by-step explanation:
-4+5y =13 add 4 both side
4-4+5y=13+4
5y=17
5y/5=17/5 y=17/5
x-5y=21
x-5(17/5)=21
x-17=21
x=21+17= 38
In 2011, a U.S. Census report determined that 71% of college students work. A researcher thinks this percentage has changed since then. A survey of 110 college students reported that 91 of them work. Is there evidence to support the reasearcher's claim at the 1% significance level? A normal probability plot indicates that the population is normally distributed.
Answer:
Note: The full question is attached as picture below
a) Hо : p = 0.71
Ha : p ≠ 0.71
p = x / n
p = 91/110
p = 0.83.
1 - Pо = 1 - 0.71 = 0.29.
b) Test statistic = z
= p - Pо / [√Pо * (1 - Pо ) / n]
= 0.83 - 0.71 / [√(0.71 * 0.29) / 110]
= 0.12 / 0.043265
= 2.77360453
Test statistic = 2.77
c) P-value
P(z > 2.77) = 2 * [1 - P(z < 2.77)] = 2 * 0.0028
P-value = 0.0056
∝ = 0.01
P-value < ∝
Reject the null hypothesis. There is sufficient evidence to support the researchers claim at the 1% significance level.
Which is the solution to the equation 8.25 + one-fourth w = 10.75? Round to the nearest hundredth if necessary.

After a 25% discount, the price of a t-shirt was $12. What was the price before the discount?
Answer:
0.75
Step-by-step explanation:
0.75 x 16 = 12
Many of you guys think it's 16 and you are some way correct but you guys forget to multiply it by 0.75
PLZ give me good reviews :)
The price before the discount was $16.
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that, the price of the -shirt is $12 after a 25% discount.
Since a 25% discount was given, only 75% of the actual amount was paid.
Therefore, it follows;
75% = $12
1% = $ (12/75)
100% = $(12/75) × 100
100% = $16
Hence, the price before the discount was $16.
