Josie runs a 25-mile race in 5 hours. What is her speed in miles per hour?
Which of the following systems of linear equations has no solution?
Answer:
3rd choice
Step-by-step explanation:
The answer is the 3rd choice.
x cannot be 3 and 5 at the same time.
x = 3
x = 5
Subtract the first equation from the second equation.
x - x = 5 - 3
0 = 2
Since 0 = 2 is a false statement, there is no solution.
Answer: 3rd choice
matt is standing on top of a cliff 305 feet above a lake. the measurement of the angel of depression to a boat on the lake is 42 degrees. how far is the boat from Matt?
Answer:
Distance of boat from Matt = 274.5 ft (Approx.)
Step-by-step explanation:
Given:
Height of cliff = 305 ft
Angle = 42°
Find:
Distance of boat from Matt
Computation:
Tan 42° = Distance of boat from Matt / Height of cliff
0.90 = Distance of boat from Matt / 305
Distance of boat from Matt = 274.5 ft (Approx.)

2. A mother is three times as old as her daughter.
In 12 years' time she will be twice as old as her daughter will be then.
How old is the mother no.w?
Answer:
The mother is 36 years now.Step-by-step explanation:
x - the age of the daugther now
3x - the age of the mother now
x + 12 - the age of the daugther in 12 years' time
3x + 12 - the age of the mother in 12 years' time
The mother will be twice as old as her daughter will be then:
3x + 12 = 2·(x + 12)
3x + 12 = 2x + 24 {subtract 2x from both sides}
x + 12 = 24 {subtract 12 from both sides}
x = 12 (the age of the daughter now)
3x = 3·12 = 36

Answer:
isosceles right
Step-by-step explanation:
The three angles total 180°, so you have ...
x° +x° +2x° = 180°
4x = 180
x = 45
2x = 90
The largest angle is a right angle (90°).
A triangle with measures of 45°, 45°, and 90° is an isosceles right triangle.

Hi I really need this question answered use the screenshot
Answer:
The picture is at the bottom
Step-by-step explanation:
Here are all of the angles:
use these rules:
-the diagonals bisect the angles they cut into
- the diagonals form a 90 degree angle with each other
- the interior angles of a triangle add up to 180 degrees
- the opposite angles of a smaller where the smaller diagonals are, are equal
- the total angles of a quadrilateral is 360 degrees

The main height of a basketball team is 6 feet with the standard deviation of 0.2 feet. The team center is 6.9 feet tall. Find the center Z score. Is the score unusual?
Complete Question
The mean height of a basketball team is 6 feet with the standard deviation of 0.2 feet. The team center is 6.9 feet tall. Find the center Z score. Is the score unusual?
Answer:
Center Z score = 4.5
The score is unusual
Step-by-step explanation:
The mean height of a basketball team is 6 feet with the standard deviation of 0.2 feet. The team center is 6.9 feet tall. Find the center Z score. Is the score unusual?
The formula for z score is:
z = (x-μ)/σ, where
x is the raw score = 6.9feet
μ is the population mean = 6feet
σ is the population standard deviation = 0.2 feet
Hence:
Z = 6.9 - 6/0.2
Z = 0.9/0.2
Z = 4.5
Yes this score is unusual

30=-6x+6
Solve the equation
Answer:
-4
Step-by-step explanation:
24 = -6x
-4 = x
............
Answer:
x = -4
Step-by-step explanation:
30 = - 6x + 6
- 6x = 30 - 6
- 6x = 24
- x = 24 / 6
- x = 4
x = - 4
1x+2x+3x=180 find the measure of each angles.
Answer:
x=30 is the answer no hate if I'm wrong :)
Step-by-step explanation:
The sum of angles in a triangle is 180 so we add them all and we get x=30.
Then find the measure of each angle by substitution.

Melanie surveyed 4 people to find out the ages of their cars and the distance they drive each day.
• Lara said her car is 4 years old, and that she drives 34 miles in the morning and 38 miles in the evening each day.
• Jamal said his car is 6 years old, and that each day he drives 56 miles total to go back and forth to work and 8 miles total to drive
his children to and from school.
• Cala said her car is 2 years old, and that she drives 18 miles each day.
. Ali said his car was 2 years old when he purchased it and that he's owned it for 6 years. He also said that he drives 7 miles to
school, 2 miles to soccer practice, and 6 miles back home each day.
Enter your answers in the boxes to complete the data table.
Answer:
2/13,140
4/105,120
6/40,832
8/35,100 or 6/23,400
Step-by-step explanation:
Cala's car is 2 years old, drives 18 miles per day times 365 days in a year times 2 years old is 13,140 miles in 2 years.
Lara's car is 4 years old, drives 72 miles a day times 365 days in a year times 4 years old is 105,120 in 4 years.
Jamal's car is 6 years old, drives 64 miles per day times 365 days a year times plus 56 miles a week times 52 weeks in a year times 6 years old is 40,832 in 6 years.
Ali's car was 2 years old when he got it 6 years ago. His car is 8 years old and he drives 15 miles per day times 52 weeks in a year for 5 days each week, times 6 years is 23,400miles in 6 years. If you average what he drives per year and add that to 23,400, the car has approximately 35100 miles in 8 years.
6.x = 4y2-12 (4y2 here means 4 y squared)
Work out the value of x when y = 5
Answer:
88
Step-by-step explanation:
Given
x = 4y² - 12 ← substitute y = 5
x = 4(5)² - 12 = 4(25) - 12 = 100 - 12 = 88

At a grocery store salted peanuts in the shell cost 30¢. Is $5.00 enough money to buy 1 pound? If so how much money will be left over?
Answer:
Yes
20 cents
Step-by-step explanation:
Assuming the cost of peanuts is 30 cents per ounce.
We have to find the cost of 1 pound of peanuts.
We know that,
1 pound = 16 ounces
$1 = 100 cents
Cost of 1 pound peanuts = 30 x 16
= 480 cents = $4.80
Yes, $5.00 is enough to buy 1 pound peanuts.
Money left = $5- $4.80 = $0.20
Money left is equal to 20 cents.
YOOOO SOMEONE HELP ME
Answer:
180 degrees in either direction
Step-by-step explanation:
picture it on a piece of paper, if you turn it once, the image becomes longer vertically, but if you flip it again, it looks like it does originally. If this is confusing, actually draw it and see how many times you need to rotate the page to make it look identical to the one you posted. 1 turn = 90 degrees.

This scatter plot has a strong positive linear relationship
Hello can someone pls help me with this!
Answer:
slope = 6x
Step-by-step explanation:
the formula to find slope between 2 points is "m = (y2 - y1)/(x2-x1)", or "m = rise/run". so when you plug in the numbers, you get "m = (12 - 6)/(2 - 1)", which gives you "m = 6/1", which is just 6x.
Answer:
Slope = 6
Step-by-step explanation:
From the graph we get:
(x1, y1) = (1, 6) and
(x2, y2) = (2, 12)
Slope = (y2 - y1) / (x2 - x1)
= (12 - 6) / (2 - 1)
= 6 / 1
= 6
Which of the following is an inequality sentence?
[tex] \text{A. \: \: x + 5 = 20}[/tex]
[tex] \text{B. \: \: x = 5}[/tex]
[tex] \text{C. \: \: x < 5}[/tex]
[tex] \text{D. \: \: x + 5}[/tex]
Answer:
[tex]C. x<5[/tex]
Step-by-step explanation:
Option A [tex][x+5=20][/tex]tells us that: When we add 5 to a variable x, we get 20. As it has a unique value for x and is completely equal to it(i.e. 15), It is an equality.Option B[tex][x=5][/tex] tells us that: A variable x equals to 5. Hence, as x is unique for 5 and is wholly equal to it, it's an equality too.Option C[tex][x<5][/tex] tells us that: A variable x isn't 5 but lesser than it. As we cannot equate it to 5, nor we are given the nature of the variable x, it is an Inequality.Option D[tex][x+5][/tex] is an expression; It can't be called an equation or an inequality unless we relate it with another expression.Step-by-step explanation:
C.x<5 is an inequality sentence.
