Answer:
45%
Step-by-step explanation:
Simply divide your partial amount (18 in this case) by your total (40), and you then multiply your answer from 18/40= .45 by 100, and you get 45. This is 45%
45% because math said so
18÷40= .45
.45•100=45

If triangle DEF is dilated by a scale factor of 1/2 with center of dilation at the origin
(0,0), what is the x-coordinate of E'?
Please help 20 points
Answer:
(4,2)
Step-by-step explanation:
I am not able to see your screen well but these are the points that I saw in the beginning for E. 8,4. Your x value is either left or right and your y value is up and down. I saw 8 units right and 4 u it's up. Now your scale factor is 1/2. Remember if the scale factor is less than one the figure reduces. Our rule for dilations is (x,y) → (kx,ky). The scale factor is represented by K. Since your scale factor is 1/2 we know our triangle will reduce. Let's plug 1/2 in our x and y valued.
So E is (8,4). 8*1/2 is 4 and 4* 1/2 is 2. Are new points are E' (4,2).

Answer:
I believe the answer would be A.
Step-by-step explanation:
You can get rid of B. and C. since it is in the middle. The highest would be at the top/right side and the lease would be at the bottom/left side. Then the total score does not make much sense because you would have to add up every number
A figure is dilated by a scale factor of 1
39
Explain whether the image is larger than,
smaller than, or the same size as the
original figure.
Responder:
Si el factor de escala de una figura es mayor que uno, la figura es mayor.
Explicación paso a paso:
Hará que la figura sea más grande porque si es menor que uno, la figura será menor. Por ejemplo, si el factor de escala es la mitad de la cifra, será la mitad más pequeña que la cifra original. Y si el factor de escala es 2, la figura será dos veces más grande que la figura original.

Answer:
120°
Step-by-step explanation:
If the line were to continue down to form a triangle at the bottom, it would cross the line with an interior angle of 70°. Since we have two of the angles, we subtract them from 180°.
180-70-50=60°
That would be the third interior angle at the top of the triangle. Angle x is supplementary to that.
180-60=120°
what is 2x + 7x + 8a + 9a
Answer: 9x + 17a
Step-by-step explanation:
2x + 7x + 8a + 9a
2x+7x= 9x
8a+9a= 17a
= 9x +17a
Answer:
9x + 17a
Step-by-step explanation:
9x + 17a. (A side note is that you can't add x and a together because they are different variables.)

Inequality
Answer:
5 < x < 7
Step-by-step explanation:
- Move all terms not containing x from the center section of the inequality.
25 < 5 x < 35
- Divide each term in the inequality by 5 .
5 < 1x < 7
5 < x < 7

A 381 foot cable runs from the top of a radio tower to a skate in the ground. If it hits the ground 167 feet from the base of the tower , what is the angle of elevation that is makes with the ground?
Answer:
64°
Step-by-step explanation:
Using Pythagoras rule :
Cosθ = adjacent / hypotenus
Adjacent = 167
Hypotenus = 381
Cosθ = 167 / 381
Cosθ = 0.4383202
θ = Cos^-1(0.4383202)
= 64.003
Hence, angle of elevation = 64°

There are GCF of two numbers is three and the LCM is 180. If one of the numbers is 45,what is the other number ?
Answer:
The other number is 12
Step-by-step explanation:
There are GCF of two numbers is three and the LCM is 180. If one of the numbers is 45,what is the other number ?
Let us represent the other number as x
There are GCF of two numbers is three and the LCM is 180.
Therefore:
45 × x = 3 × 180
45x = 3 × 180
x = 3 × 180/45
x = 12
Therefore, the other number is 12

Answer:
A -125
Step-by-step explanation:
because they went over 100ft below sea level
and if sea level is exactly 0 and they went under it over 100 the only option over 100 with a negative sign to show they went below sea level would be -125

Find the simple interest paid and the amount paid for the loan.
$4800 at 9.9% for 4 years
Answer:
$1900.80
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 9.9%/100 = 0.099 per year,
then, solving our equation
I = 4800 × 0.099 × 4 = 1900.8
I = $ 1,900.80
The simple interest accumulated
on a principal of $ 4,800.00
at a rate of 9.9% per year
for 4 years is $ 1,900.80.
