24 4/8 - 19 5/8 STEP BY STEP EXPLANATION
Answer:
First, in order to subtract these two fractions you must convert it into improper fractions. For the first one, we can convert it by multiplying the denominator by the whole and adding the numerator which would give you 196/8 for the first one and 157/8 for the second one. This equation would now set up as 196/8-157/8 which would be 39/8 and since you need to convert it back into a mixed fraction we need to know how many times 8 can go into 39 which is 4 so 32 and a remainder of 7. Your answer would be 4 7/8

The length of two sides of a triangle are 4 inches and 7 inches.
What is the area to that triangle?
Answer:
Hi! answer: Area = 14
Step-by-step explanation:
When finding area we do base x height ÷ by 2
So I do 7 x 4 = 28 then I divide that by 2 and get 14 Hope this helps!
If Kavita is 'x' years old now then the age of Kavita after ten years will be
A. x + 10
B. 2x - 10
C. 2x + 10
D. x - 10
Answer:
A
Step-by-step explanation:
Kavita is x years old, so 10 years later, her age will be x years plus the next ten. Or, x + 10.
To check this, let's suppose Kavita is 17 years old. In 10 years, she'll be 27.
Substitute the x for our hypothetical age, 17, and our answer, 27, and calculate.
x + 10 = 27
17 + 10 = 27
27 = 27
The equation is true, so we have a true statement. The answer is A, x + 10.

A 6 sided cube with sides labeled 1,2,3,4,5 and 6 is rolled 50 times. What is a good prediction for the number of times 5 will be rolled?
Answer:
A good prediction is that the number 5 will be rolled 8 times
Step-by-step explanation:
Here, we want to get the number of times 5 would occur in a roll of 50
firstly, we need the probability of having a 5 come up
To do this, we have to divide the number of 5’s by the count of possible numbers
We have this simply as 1/6
Now, we have to multiply this by 50
we have this as;
1/6 * 50 = 8.333
This is approximately 8
so we have it that in 50 rolls, we can have the number 5 coming up 8 times

The price of 2 pears and 6 apples is $14. The price of 3 pears and 9 apples is $21. Can you determine the unit prices for pears and apples?
really need help 30 points so dont scam me xD
Answer:
If 2p + 6a = $14
and 3p + 9a = $21
then the following would also be true:
1p + 3a = $7
If p = pear and a = apple, how much would each cost? The unit prices can be determined by looking at the pattern. You can use multiplication to solve the problem.
For example, 1p + 3a*2 = $7
p = $1/each
a = $2/each or $6 total
can you please help me solve these?

Circle A is located at (6, 5) and has a radius of 3 units. What is the equation of a line that is tangent to circle A from point C (9, 8)?
y = −x + 14
x = 9
y = x − 1
x = 4
Answer:
2nd
Step-by-step explanation:
The equation of a line that is tangent to circle A from point C (9, 8) will be option C; y = x − 1.
How to get straight line equation?If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:
y = mx +c
Given; Circle A is located at (6, 5) and has a radius of 3 units.
The slope;
m = (8- 5)/(9 -6) = 1
Substitute in the equation of line;
y = mx +c
8 = 1(9) + c
8 - 9 = c
c = -1
So, We get
y = x − 1
Hence the equation of a line that is tangent to circle A from point C (9, 8) will be option C; y = x − 1.

The square of a negative integer has the same value as the sum of that integer plus 2. what is the integer?
Answer:
I don't know bc I can't figure it out sry
An equation is formed of two equal expressions. The negative integer stated in the statement is 1.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the negative integer be represented by -a.
Given that the square of a negative integer has the same value as the sum of that integer plus 2. Therefore, the equation can be written as,
(-a)² = -a + 2
a² = -a + 2
a² + a -2 = 0
a² +2a - a -2 = 0
a(a+2) -1(a+2) = 0
(a-1)(a+2) = 0
a = 1, -2
Since a was a negative integer and we have already used the negative sign in the equation, therefore, the value of a is 1.
Hence, the negative integer stated in the statement is 1.

analia wants to know which school has higher athletic achievement relative to the budget per student
Answer:
SAT average divided by budget per student
Graduation rate divided by budget per student
No. The definitions have opposite results.
Step-by-step explanation:
DID IT ON KHAN and
The key understanding here is that there isn't a single way to define "academic achievement." Graduation rate can be a good measure of that. Average SAT is also a good measure. The rate of students who are accepted into college can also be a good measure, but we are not given information about that.
Now let's go over the options and see which of them might be used to describe "academic achievements relative to the budget per student."

You would like to lease a car worth $52,696 for a three-year period. The leasing company told you that after three years, the car would have a residual value of $39,826. What percentage represents the residual value of your leased car?
Answer: 75.58%
Step-by-step explanation:
Since we are given the information that the worth of the car will be leased for $52696 and the residual value will be $39826, the percentage that represents the residual value of the leased car will be:
= (39826 / 52696) × 100
= 0.7558 × 100
