Answer:
12.75
Step-by-step explanation:
first divide 17 by 100 which is 0.17
then multiply that by the percentage off in this case it is 25 and equals 4.25
then subtract the answer(4.25) you just got by 17
that equals 12.75

Using the function g(x) = -2x + 5, what would the input need to be for an output of -5? a.5 b.0 c.15 d.-5
Answer:
A
Step-by-step explanation:
We are given the function g(x) = -2x +5
If we need an output of -5, then:
-5 = -2x + 5
-10 = -2x
x = 5
A
Answer:
a. 5
Step-by-step explanation:
We can solve this by simply guessing and checking; plugging in each answer until we get -5.
a) -2(5) + 5
-10 + 5
-5
We can also set the function equal to -5 and solve for x.
-2x + 5 = -5
-2x = -10
x = 5

Answer:
6
Step-by-step explanation:
since it's a right triangle you can use the Pythagorean Theorem
2.7² + b² = 6.5²
7.29 + b² = 42.25
b² = 34.96
b = [tex]\sqrt{34.96}[/tex] which equals 6 when rounded to the nearest tenth
Luke, Kira and Ali each served 2/3 of their own cake. Each cake was the same size, but luke served 4 slices, Kira served 6 slices and Ali served 8 slices. How is this possible?
Answer:
The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.
Step-by-step explanation:
It's possible because they cut cakes into different number of slices.
You know that Luke, Kira and Ali each served [tex]\frac{2}{3}[/tex] of their own cake and Luke served 4 slices, Kira served 6 slices and Ali served 8 slices.
Being x the whole slices of cake, and if Luke served [tex]\frac{2}{3}[/tex] of his cake, which are 4 slices, the whole slices of cake of Luke is:
[tex]\frac{2}{3}*x=4 slices[/tex]
Solving:
x= 4 ÷[tex]\frac{2}{3}[/tex]
x= 6
Then, whole slices of Luke's cake is 6.
Performing the same approach for Kira you get:
[tex]\frac{2}{3}*x=6 slices[/tex]
x= 6 ÷[tex]\frac{2}{3}[/tex]
x= 9
Then, whole slices of Kira's cake is 9.
Finally, performing the same approach for Ali you get:
[tex]\frac{2}{3}*x=8 slices[/tex]
x= 8 ÷[tex]\frac{2}{3}[/tex]
x= 12
Then, whole slices of Ali's cake is 12.
The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.

The mean of three numbers is 10. The mean of other four numbers is 12. Find the mean of all the numbers.
Answer:
11.14
Step-by-step explanation:
Mean = sum of numbers / total numbers
the mean of the 7 numbers = sum of the numbers / 7
sum of numbers for the 3 numbers = 10 x 3 = 30
Sum of numbers for the other 4 numbers = 12 x 4 = 48
Sum of the 7 numbers = 48 + 30 = 78
Mean of the 7 numbers = 78 / 7 = 11.14
Find (f • g)(-1).
f(x) = x + 1
g(x) = x^2 + 5x
Answer:
cc
Step-by-step explanation:
c
Answer:
0
Step-by-step explanation:
(gf)(x)=(x+1)(x2+5x)
gf(x)=x3+5x2+x2+5x
gf(x)=x3+6x2+5x
gf(-1)=(-1)3+6(-1)2+5(-1)
gf(-1)=-1+6(1)-5
gf(-1)=-1+6-5
gf(-1)=6-6
gf(-1)=0
Suppose point A is located at (1, 3) on a coordinate plane. If AB is 10 and the x-coordinate of point B is 9, explain how to use the Distance Formula to find the y-coordinate of point B.
Answer:
y =9
Step-by-step explanation:
you know the distance is 10 and some of the x,y points. so start filling what you know into the distance formula
10= √((9-1)^2 + (y-3)^2 )
square both sides to get ride of the square root
100 = 64 + (y-3)^2
36 = (y-3)^2
6 = y-3
y = 9
double check by using 9 for Y and you'll see it works.

A shop has 400 bulbs
out of which 24 are defective What percent are good bulb?
Answer:
look at the picture i sent plz......
Answer:
Number of non defective bulbs-
400-24
376
Our fraction would be-
376/400
To make it into percentage we need to always multiply it by 100
376/400 x 100
=94%
Thus 94% of the bulbs are non defective
Bank A is lending money at 6.4% interest compounded annually. The rate at Bank B is 6.3% compounded monthly, and the rate at Bank C is 6.35% compounded daily. Determine the amount of interest you would earn at each bank if you invest $1500 for 12 months.Which bank will you pay the least amount?
Answer:
$1596
$1597.28
$1598.33
bank A
Step-by-step explanation:
The formula for calculating compound interest:
FV = P (1 + r/m)^mn
FV = Future value
P = Present value
R = interest rate
N = number of years
m = number of compounding
Bank A = $1500(1.064) = $1596
Bank B = $1500( 1 + 0.063/12)^12 = 1597.28
Bank C = $1500( 1 + 0.0635/365)^365 = $1598.33
Bank A pays the least amount of interest

Assuming you require to find x
4x - 3 and 115 are same- side interior angles and supplementary, sum to 180°
4x - 3 + 115 = 180
4x + 112 = 180 ( subtract 112 from both sides )
4x = 68 ( divide both sides by 4 )
x = 17

Step-by-step explanation:
The mistake is that they did not need to divide the radius by two since the radius is already half of the diameter. The area of a circle is pi*r^2. The second mistake they made was that they assigned pi the value of 3 which is wrong. After calculating, the area of the circle is 53^2pi = 8824.73mm^2
The legs of a right triangle measure 10 m and 24 m. What is the length of
the third side of the right triangle?
Answer:
26
Step-by-step explanation:
100 +(24^2) = 676
square root of 676 = 26
Answer:
either 26 m or 21.8174 m
Step-by-step explanation:
If 24 is the hypotenuse, then 24^2-10^2=x^2
x^2=576-100=476
x=21.8174 m
if x=hypotenuse, then 24^2+10^2=x^2
x^2=576+100=676
x=26 m
(x - 1)/(n - 1) + (2n ^ 2 * (1 - x))/(n ^ 4 - 1) = (2x - 1)/(1 - n ^ 4) - (1 - x)/(1 + n)
