What is the area of this shape?
A. 42 cm squared
B. 35 cm squared
C. 26 cm squared
D. 14 cm squared
Answer:
A. 42 cm²
Step-by-step explanation:
Rectangle Area: lw
Put the measurements into the expression
(7)(5)
7•5 = 35
Triangle Area: 1/2bh
1/2(7)(2)
1/2(14)
7
Add them together: 35 + 7 = 42 cm²
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
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
Two possible plans for a new bathroom are shown. Is there a value of x for which the perimeters are equal? Show your work. Explain the reasoning.
Answer:
There is no value of x to fit this requirement.
Step-by-step explanation:
The 2 perimeters in terms of x are:
4(x + 3) for the square and
2(x+1) + 2(x +4) for the rectangle
and these need to be equal so
we equate these 2 and solve for x:
4(x + 3) = 2(x+1) + 2(x +4)
4x + 12 = 2x + 2 + 2x + 8
4x + 12 = 4x + 10
4x - 4x = 10 - 12
0 = -2 which is of course absurd so there is no solution to this equation.
Answer:
(x+3)•4=(x+4)•2+(x+1)•2
Step-by-step explanation:
4x+12=2x+8+2x+2
4x-2x-2x=-12+8+2
0=-2
this expression is indeterminate.

Factor the left side.
What two numbers when multiplied yield 3 but when added yield the middle coefficient -4?
How about -1 times -3?
Yes, (-1)(-3) is 3 but when added yield -4.
(x - 3)(x - 1) = 0
Set each factor to 0 and solve for x.
x - 3 = 0
x = 3
x - 1 = 0
x = 1
The word root is just another word for solution or the zero of a polynomial.
Answer: x = 1 or x = 3 are the roots.

Tom's earnings vary directly with the number of hours he works. Suppose that he worked 9 hours yesterday and earned $126. How much will he earn today if he works 8 hours?
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.
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
QUICK PLEASE!!!
answer this question and show work or have an explanation.
Answer:
70
Step-by-step explanation: Triangle angle sum theorem states the interior angles of a triangle sum to 180 degrees. We know one angle is 40 degrees and the two remaining angles are equal in measure.
Since angle J and angle L are equal in measure we can substitute 2x for angles J and L into the equation.
40 + 2x = 180. Subtract 40 from both sides.
2x = 140. Divide both sides by 2.
X = 70

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.

What is the average rate of change over the interval 1≤x≤3
9514 1404 393
Answer:
3
Step-by-step explanation:
The average rate of change is the slope of the line between the points at the ends of the interval: (1, -2) and (3, 4). That is given by the slope formula ...
m = (y2 -y1)/(x2 -x1)
m = (4 -(-2))/(3 -1) = 6/2
m = 3
The average rate of change on the interval is 3.

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.

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
