Answer:
The center is (7,5) and the radius is 2
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-7)^2+(y-5)^2=2^2
The center is (7,5) and the radius is 2

A rectangle with a width of 2.5 cm and a length of 3 cm is dilated by a scale factor of 4. Which statements about the new
rectangle are true? Check all that apply.
The dimensions of the new rectangle will be 10 cm by 12 cm.
The dimensions of the new rectangle will be 40 cm by 48 cm.
The new perimeter will be 4 times the original perimeter.
The new perimeter will be 16 times the original perimeter.
The new area will be 4 times the original area.
The new area will be 16 times the original area.
The new perimeter will be 44 cm.
The new area will be 30 square cm
Answer:
The new perimeter will be 4 times the original perimeter.
The new area will be 4 times the original area.
Step-by-step explanation:
The area and perimeter of new rectangle will be 120 square cm and 44 cm. Then the correct options are A, C, F, and G.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
A rectangle with a width of 2.5 cm and a length of 3 cm is dilated by a scale factor of 4.
L = 3 cm
W = 2.5 cm
Then the new dimension of the rectangle will be
W' = 4 x 2.5 = 10 cm
L' = 4 x 3 = 12 cm
Then the perimeter of the rectangle will be
P = 2(L + W)
Then the perimeter of the new rectangle will be
P = 2(4L + 4W)
P = 4 x 2(L + W)
The new perimeter is the 4 times of original perimeter.
P = 8(2.5 + 3)
P = 44 cm
The area of the rectangle will be
A = L x W
Then the area of the new rectangle will be
A = 4L x 4W
A = 16 x L x W
The new area is the 16 times of original area.
A = 16 x 2.5 x 3
A = 120 square cm
Then the correct options are A, C, F, and G.

Answer:
54
Step-by-step explanation:
Diagonals are perpendicular so
2x+ 90 + 3x = 180 since this forms a triangle
Combine like terms
5x+ 90 = 180
Subtract 90 from each side
5x +90-90 =180-90
5x = 90
Divide each side by 5
5x/5 = 90/5
x =18
We want to find Angle ABD
ABD = 3x = 3*18 = 54
Answer:
HOPE THIS HELPS PLS DON"T TAKE IT DOWNN
Step-by-step explanation:
Say that the intersecting point of both diagonals is O
that means that in triangle AOB, all angles add up to 180º that is just the definition of sum of angles in a triangle
and the m<AOB = 90º, diagonals in a rhombus are perpendicular
that means that
90º + 2x + 3x = 180º
90º + 5x = 180º
5x = 90º
x = 18º
if m<ABD = 3x
then its equal to m<ABD = 3(18)
m<ABD = 54º

You get a student loan from the New Mexico Educational Assistance Foundation to pay for your educational expenses this year. Find the interest on the loan if you borrowed $2,000 at 8.5% for 3 year.
Answer:
$554.58
Step-by-step explanation:
The interest on the loan can be computed by first determining the future value of the loan in three years as follows:
FV=PV*(1+r)^n
PV is the amount of the loan which is $2,000
r is the interest rate which is 8.5%
n is the number of years which is 3 years
FV=$2000*(1+8.5%)^3=$ 2,554.58
Since the value of the loan in three years is $ 2,554.58 ,the interest on the loan is the difference between the future value and the present value
interest=$ 2,554.58-$2,000.00=$554.58
When Colton commutes to work the amount of time it takes him to arrive is normally distributed with a mean of 41 minutes and a standard deviation of three minutes what percentage of his commute will be between 33 and 35 minutes to the nearest tenth?
Answer:
The Probability that commute will be between 33 and 35 minutes to the nearest tenth = 0.0189 ≅1.89%
Step-by-step explanation:
Step(i):-
Given mean of the Population(μ) = 41 minutes
Given standard deviation of the Population (σ) = 3 minutes
let 'X' be the random variable of Normal distribution
Let X = 33
[tex]Z = \frac{x -mean}{S.D} =\frac{33-41}{3} = -2.66[/tex]
let X = 35
[tex]Z = \frac{x -mean}{S.D} =\frac{35-41}{3} = -2[/tex]
Step(ii):-
The Probability that commute will be between 33 and 35 minutes to the nearest tenth
P(33≤ X≤35) = P(-2.66 ≤X≤-2)
= P( X≤-2) - P(X≤-2.66)
= 0.5 - A(-2) - (0.5 - A(-2.66)
= 0.5 -0.4772 - (0.5 -0.4961) (From normal table)
= 0.5 -0.4772 - 0.5 +0.4961
= 0.4961 - 0.4772
= 0.0189
The Probability that commute will be between 33 and 35 minutes to the nearest tenth = 0.0189 ≅1.89%

-7
Answer:
-7
Step-by-step explanation:
-7 is a solution of the inequality t<-6
By the way, for the number -6, you can think about a temperature below zero. When it is freezing 6 degrees below zero (-6) it is pretty cold.
The question is which number(s) can you substitute for t so that the formula (the inequality) is True.
So let's try for each given value and substitute it for t in t<-6
if you substitute 7 for t you get this:
Is 7 smaller then -6 ?
No that is not true because 7 is bigger then -6.
if you substitute 7 for t you get this:
Is 7 smaller then -6 ?
No that is not true because 7 is much bigger then -6.
if you substitute 6 for t you get this:
Is 6 smaller then -6 ?
No that is not true because 6 is much bigger then -6.
if you substitute -6 for t you get this:
Is -6 smaller then -6 ?
No, that is NOT true because -6 is exactly the same as -6 but NOT smaller then -6...
if you substitute-7 for t you get this:
Please think about temperatures below zero again.
Is -7 colder the -6 ? If so, then the statement is true...
Is -7 smaller then -6 ?
Yes that is true!
So -7 is a solution of the inequality t<-6

The temperature was 54 at 7:00 a.m. At 3:00 p.m. on the same day, the temperature was 82. What is the rate of change in temperature during this time?
Answer:
The rate of change was 3.5 degrees / h.
Step-by-step explanation:
In order to calculate the rate of change we need to divide the variation of temperature by the variation of time. Since the time is given to us in a 12 h format (am/pm), we first need to convert it to 24 h. To do that we sum the time that is "pm" by 12, we have:
time2 = 3 + 12 = 15
Therefore the rate of change in temperature is:
rate = variation of temp / variation of time
rate = (temp final - temp init) / (time final - time init)
rate = (82 - 54) / (15 - 7) = 28 / 8 = 3.5 degrees / h
The rate of change was 3.5 degrees / h.
A card is drawn from a standard 52-card deck. What is the probability that the card is a red card, or that it is a ten of clubs or a jack of clubs? A. 1/52 B.3 /26 C. 7/13 D.15 /26
Answer:
Step-by-step explanation:
I'm not sure whether you're asking for the probability of each condition individually or the probability of the last two together, but I'll do both.
Probability that the card is red: 26/52, aka 1/2 or 50%
Probability that the card is a ten of clubs: 1/52
Probability that the card is a jack of clubs: 1/52
Probability that the card will be either a ten of clubs or a jack of clubs: 2/52
Which of these is NOT equivalent to 2-37
