Answer:
The image of the point is (8, 4)
Step-by-step explanation:
If the point (x, y) dilated by a scale factor k centered at the origin, then its image is (kx, ky)
Let us solve the question
∵ The point is (2, 1)
∴ x = 2 and y = 1
∵ The point dilated by a scale factor of 4 centered at the origin
∴ k = 4
→ By using the rule above multiply each coordinate of the point by 4
∵ The image of the point is (kx, ky)
∵ kx = 4 × 2
∴ kx = 8
∵ ky = 4 × 1
∴ ky = 4
∴ The image of the point is (8, 4)
9x +17 =4y
Solve for slope
Solve for y-intercept
Answer:
y=9x/4+17/4
comparing with y=mx+c
m(slope)=9/4
c(y intercept)=17/4
What is the surface area?
Answer:
0.5 X 15 X 20 = 150m squared
150 X 2 = 300m squared (that's the two triangles done)
25 x 7 = 175m squared (front)
15 X 7 = 105m squared (base)
20 X 7 = 140m squared (back)
now add them all together
300 + 175 + 105 + 140 = 720
SA = 720cm squared
Answer:How do u find the surface area of a cube?
To determine the surface area of a cube, calculate the area of one of the square sides, then multiply by 6 because there are 6 sides. This is the same as solving using the formula SA = 6s2. If you are given the surface area, you can determine the side length by working backwards.

Is 3^2 ⋅ 3^−5 equivalent to 1/3^-3
Answer: No
Step-by-step explanation:
3^2 * 3^-5 = 3^(2+-5) = 3^-3, and 3^-3 is obviously not 1/3^-3.
Hope that helped!
Dennis read 30% of his book on Tuesday and of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?
Answer:
1/2x
Step-by-step explanation:
Dennis read 30% of his book on Tuesday and 1/5 of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?
Total pages of the book = x
Tuesday = 30%
= (30/100)x
= 3/10x
Wednesday = 1/5x
3/10x + 1/5x
= 3x+2x/10
= 5/10x
= 1/2x
what fractional part of the book did he have left to read after Wednesday
= x - 1/2x
= 2x-x/2
= x/2
= 1/2x
2x + 1 = 9
is that the answer ?
Answer:
yes
Step-by-step explanation:
because 9-1=8/2 equals 4 so2x4+1=9

How much would your total be if you bought 5 lbs of apples
and 4 lbs of oranges?
Answer:
So apples would cost $2.95 and oranges would cost $1.92 then you would add those two together to get $4.87.
Step-by-step explanation:
Apples you would do 0.52×5 and get $2.95 and for oranges you would do 0.48×4 to get $1.92, then you just add the two numbers together.
WEST is a parallelogram. If mze = (3x – 18)º, mzw
find the value of y and mus.
(15y + 6)°, and m2T = (2x + 6),
9514 1404 393
Answer:
m∠W = m∠S = 126°
m∠E = m∠T = 54°
x = 24
y = 8
Step-by-step explanation:
Opposite angles of a parallelogram are congruent, so we have ...
∠E = ∠T
3x -18 = 2x +6
x = 24 . . . . . . . . . add 18-2x
Then the measure of these angles (in degrees) is ...
∠E = ∠T = 2x+6 = 2(24) +6 = 54
__
The adjacent angle W is supplementary to either of these:
∠W = 180° -∠E
15y +6 = 180 -54
15y = 120
y = 8
∠W = ∠S = 126°
Answer:
y = 8
Angle S= 126°

A shoe store buys a shipment of nike shoes that cost $70 each to the purchases. They want to markup their prices for the customers by 30%. How much would the customer pay for a pair of nikes
Given :
A shoe store buys a shipment of Nike shoes that cost $70 each to the purchases.
They want to markup their prices for the customers by 30%.
To Find :
How much would the customer pay for a pair of Nikes.
Solution :
C.P = $70 .
It is given that selling price is 30% more than the S.P.
So, S.P = C.P + C.P×0.30
S.P = C.P×1.30
S.P = 70×1.30
S.P = $91.
Therefore, the customer would pay $91 for a pair.
What is the final amount if 784 is decreased by 1% followed by a 4% increase?
Give your answer rounded to 2 D
Answer:
807.21
Step-by-step explanation:
for the 1 % decrease
1/100 × 784 = 7.84
784 - 7.84 = 776.16
then 4% increase
4/100 × 776.16 = 31.0464
776.16 + 31.0464= 807.2064
in 2 Decimal places

Answer:890
Step-by-step explanation:
find the value of X round to the nearest tenth
Given:
In a right angle triangle triangle, the length of hypotenuse = 47 units.
One of the acute angle = 17°.
Opposite side of the given angle = X
To find:
The value of X. Round to the nearest tenth.
Solution:
In a right angle triangle,
[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]
A right triangle is crated with the help of dotted lines. In this triangle,
[tex]\sin (17^\circ)=\dfrac{X}{47}[/tex]
[tex]0.2923717=\dfrac{X}{47}[/tex]
Multiply both sides by 47.
[tex]0.2923717\times 47=X[/tex]
[tex]13.74147=X[/tex]
[tex]X\approx 13.7[/tex]
Therefore, the approximate value of X is 13.7 units.

Answer:
BD = 8
m∠BDA = 90°
∆ABD and ∆BCD are both right triangles, each with two known side lengths.

Sonya had 20 dollars to spend on 3 gifts. She spent 8 1 4 dollars on gift A and 4 4 5 dollars on gift B. How much money did she have left for gift C?
Answer:
6 19/20 dollars
Step-by-step explanation:
Sonya had 20 dollars to spend on 3 gifts.
She spent 8 1 4 dollars on gift A and 4 4 5 dollars on gift B.
Gift A + Gift B + Gift C = $20
Gift C = $20 - (Gift A + Gift B)
Gift A = $8 1/4
Gift B = $4 4/5
Hence:
The amount she had left for gift C is :
Gift C = $20 - ($8 1/4 + $ 4 4/5)
Gift C = $20 - $13 1/20
Gift C = $ 6 19/20

Martin is paid an hourly rate of d dollars per hour for the first 40 hours he works per week. He is paid one-and-a-half times his
hourly rate for each hour he works in excess of 40 hours per week.
If Martin was paid $770 for working 50 hours in one week, which equation can be used to calculate d, Martin's hourly rate of pay?
Answer:
40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.
Step-by-step explanation:
Given that:
Hourly rate = d
Earning to first 40 hours = 40d
Earning of more than 40 hours = 1.5d
Amount paid per week = $770
Hours worked = 50 hours
first 40 hours + 10 hours = total earned
40d + 10(1.5d) = 770
Hence,
40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.

Any number that isn't 3.
Step-by-step explanation:
Any other number should work, so I'll just show you what happens if you use 3.
2(3x - 2) = 6x + 5
6x - 4 = 6x + 5
-4 ≠ 5
As you are aware, that would make it no solution hence why it can't be used.

Peter is folding brochures for his Dad's new company. After 1 hour, he has 330 brochures left to fold. After 4 hours, he only has 90 brochures left to fold.
(From the above statements you should be able to create two ordered pairs. I will create one for you..... (1,330). Now you create the other ordered pair and continue with the problem.)
Write an equation in slope-intercept form, y=mx+b, that represents the number of brochures Peter has left to fold, , after a given number of hours, x.
Answer:
y = -80x + 410
Step-by-step explanation:
(1,330) is the first point, the other point is (4,90)
m = y2 - y1/x2 - x1
m = 90 - 330/4 - 1
m = -240/3
m = -80/1
m = -80
y - y1 = m(x - x1)
y - 330 = -80(x - 1)
y - 330 = -80x + 80
y = -80x + 80 + 330
y = -80x + 410
