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.

Which types of dilation are the given scale factors? Select Expansion or Contraction to correctly describe the type of dilation for each given scale factor.
Answers
Answer:
Expansion
Contraction
Expansion
Contraction
Step-by-step explanation:
The correct type of dilation for given scale factors are 1) contraction, 2) contraction, 3) expansion 4) contraction
What is dilation?Dilation is a type of transformation in geometry, in which the original figure changes its scales, either reduce or enlarge.
Given are scale factors,
Scale factor symbolized by k,
We know that, when k > 1, the figure expands or enlarge.
When k < 1, the figure reduces or contract.
And when k = 1, the figure is congruent to the dilation.
1) -5 = (contraction)
1 > -5, therefore, figure is contraction.
2) -1/4 = (contraction)
1 > -1/4, therefore, figure is contraction.
3) 3.5 = (expanding)
1 < 3.5, therefore, figure is expanding.
4) 6/7 = (contraction)
6/7 = 0.8571 < 1, therefore, figure is (contraction)
Hence, -5 = (contraction), -1/4 = (contraction), 3.5 = (expanding) and 6/7 = (contraction)

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.
Answers
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.

Tickets for an all-you-can-eat pancake breakfast cost $15 each. Which equation shows the relationship between c, the total cost of the breakfast tickets and t, the number of breakfast tickets bought? * 5 points c = 15t t = 15c c = t + 15 t = c + 15
Answers
Answer:
a) c = 15t
Step-by-step explanation:
c = the total cost of the breakfast tickets
t = the number of breakfast tickets bought
Tickets for an all-you-can-eat pancake breakfast cost $15 each
Therefore, the equation that shows the relationship between c, the total cost of the breakfast tickets and t, the number of breakfast tickets bought is written as:
c = $15 × t
c = 15t

Answers
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

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
The measure of ∠A is 12° greater than the measure of ∠B. The two angles are complementary. Find the measure of each angle.
The m∠A is __° and m∠B is __°.
Answers
Answer:
39° = m∠A
51° = m∠B
Step-by-step explanation:
Complementary angles have a sum of their measures = 90
Let x = m∠B
then x + 12 = ∠A
m∠A + m∠B = 90
x + 12 + x = 90
2x + 12 = 90
2x = 78
x = 39° = m∠A
x + 12 = 39 + 12 = 51° = m∠B
The measure of ∠A is 39°.
The measure of ∠B is 51°.
Here,
The measure of ∠A is 12° greater than the measure of ∠B.
The two angles are complementary.
We have to find the measure of each angle.
What is Complementary angle?
Complementary angles have a sum of their measures is 90°.
Now,
The measure of ∠A is 12° greater than the measure of ∠B.
Let m∠B = x
Then, ∠A = x + 12
The two angles are complementary.
Hence,
m∠A + m∠B = 90
x + 12 + x = 90
2x + 12 = 90
2x = 78
x = 39°
And, x + 12 = 39 + 12 = 51°
Hence, The m∠A is 39° and m∠B is 51°.

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?
Answers
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.

Answers
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.
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?
Answers
At the beginning the mother is 36 and the daughter is 12. Making her 3 times older. In 12 years the daughter would be 24 and the mother would be 48. Making her twice as old as her daughter
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
