Answer:
$40
Step-by-step explanation:
The use of the word "mental math" means round to the nearest whole. By doing this you turn $12.98 into $13 and $1.02 into $1 which will give you $40 in total. This problem doesn't need to round as it is a simple problem. The true answer is $12.98 + $17.50 + $8.50 +$1.02= $40.
b) Amount
Rs 5760, Interest
Rs 1526
Given :
Amount, A = 5760 Rs.
Interest in the amount, I = 1526 Rs.
To Find :
We need to find the % rate of interest.
Solution :
Let, us assume it is simple interest.
So,
[tex]Interest = \dfrac{price \times rate \times time}{100}\\\\1526 = \dfrac{5760 \times r \times m}{100}\\\\r = \dfrac{152600}{5760m}\\\\r = \dfrac{26.5}{m}[/tex]
Hence, this is the required solution.

Factor 8x+48 using the gcf
Answer:
16(2z -3)
Step-by-step explanation:
There are two ways of solving this problem.
List out the factors of the numbers:
32z - 48
= 32 * z - 48
32= 1, 2, 4, 8, 16, 32
48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
the largest common factor that both numbers have in common is 16,
So factoring the equations means the one has to divide the equation by 16 and write it outside of the parenthesis.
16 * ( 2 * z - 3)
16(2z -3)
Another way of solving the problem:
prime factorize the number:
32 = 2^5
48 = 2^4 * 3
Both numbers have 2^4 as their largest factor in common meaning that that is their GCF. 2^4 is 16.
Now factor out 16 and write it on the outside of the parenthesis.
16 * ( 2 * z - 3)
16(2z -3)

Which equation represents the line that passes through the points (1, 1) and
(-4, 7)?
A. 5x + 6y = 11
B. 6x + 5y = 11
C. 6x - 5y = -11
D. 5x - y = -11
PLEASE HELP
ILL GIVE YOU BRAINIEST
Answer:
Option (B)
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here m = slope of the line
b = y-intercept
Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the line which passes through the points (1, 1) and (-4, 7) will be,
m = [tex]\frac{7-1}{-4-1}[/tex]
= [tex]-\frac{6}{5}[/tex]
By substituting the value of m in the equation,
y = [tex]-\frac{6}{5}x+b[/tex]
Since, this line passes through (1, 1),
1 = [tex]-\frac{6}{5}(1)+b[/tex]
b = [tex]1+\frac{6}{5}[/tex]
= [tex]\frac{11}{5}[/tex]
Therefore, equation will be,
[tex]y=-\frac{6}{5}x+\frac{11}{5}[/tex]
5y = -6x + 11
6x + 5y = 11
Option B is the answer.
It's candy time! Suppose 5 friends go out candy collecting. Starting out, Ms. Gleason gave each of them 12 pieces of candy. Then, they each collect 15 pieces each hour. At the end of the night, the 5 friends have 510 pieces all together. How many hours were they out candy collecting? ______ hours Multi-Step Equations
Answer:
6 hours
Step-by-step explanation:
First, since they all collected 510, you divide 510 by 5, to figure out how much each person got.
You then know that each of them got 102 candies, so now, you subtract 12 from from 102, since the teacher gave them that much in the beginning.
You're left with 90, so last step is to divide 90 by 15, since they collect 15 every hour, which you get left with 6. Meaning they collected candies for 6 hours
Answer:
they were out for 6 hours and each of them got 102 pieces of candy
The solution of a system of equations with no solution describes what kind of lines?
options:

Answer:
parallel
Step-by-step explanation:
The answer is parallel because Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines

Step-by-step explanation:
Two friends shop for fresh fruit. Jackson buys a watermelon for $6.85 and 5 pounds of cherries. Tim buys a pineapple for $3.35 and 4 pounds of cherries. Use the variable p to represent the price, in dollars, per pound of cherries. Write and simplify an expression to represent how much more spent.
Answer:
3.5 + p
Step-by-step explanation:
Jackson:
Watermelon = $6.85
Cherries = 5p
Total spent = 6.85 + 5p
Tim:
Pineapple = $3.35
Cherries = 4p
Total = 3.35 + 4p
Where,
P = price per pound of Cherries
how much more spent?
Jackson's total spent - Tim's total spent
= 6.85 + 5p - (3.35 + 4p)
= 6.85 + 5p - 3.35 - 4p
= 3.5 + p

On the interval [x,7] , at which x-value is the average rate of change 56?
????????
Average rate of change of 56 at the point x=4
What is average?An average is a single number taken as representative of a list of numbers
What is rate of change?A rate of change is a rate that describes how one quantity changes in relation to another quantity
Consider the point 4
At x=4; f(x)=24
At x=7: f(x)=192
Average Rate of change = Rate of change of f(x) / Rate of change of x
Average rate of change =[tex]\frac{192-24}{7-4}=\frac{168}{3}[/tex]
Average rate of change = 56
Hence, the average rate of change of 56 at the point x=4
