Xuan sold 9 used books for $9.80 each. With the
money from these sales, she bought 4 new books and
had $37.80 left over. What was the average amount
Xuan paid for each new book?
A. $ 5.60
B. $ 9.45
C. $10.08
D. $12.60
E. $22.05
Answer:
I think the answer is A, $5.60
Step-by-step explanation:
9.80 x 9= 88.20
88.20 - 37.80 = 50.40
5.60 x 9 = 50.40
The average amount paid for the books is $12.60
Since Xuan sold 9 used books for $9.80 each, the total amount that's paid for the books will be:
= $9.80 × 9
= $88.20
Since she bought 4 new books and had $37.80 left over, the cost of the books will be
= $88.20 - $37.80
= $50.40
Since she bought 4 books, the average amount paid for the books will be:
= $50.40/4
= $12.60
Therefore, the correct option is D

In parallelogram ABCD, the measure of angle A is 99°. What are the measures of the other 3 angles? Explain how you know.
Answer:
B:81
C:99
D:81
Step-by-step explanation:
In a parallelogram, opposite angles are congruent and consecutive angles (angles next to each other) are supplementary, or add to 180. Considering that there is no diagram, we can use our imagination here. So B is next to A, so <A+<B=180. <B must equal 81. I repeated this process for the rest of the angle measures.
[tex]\\ \sf\longmapsto <A=<C=99°[/tex]
sum of corresponding angles is 180°
[tex]\\ \sf\longmapsto <A+<B=180[/tex]
[tex]\\ \sf\longmapsto 99+<B=180[/tex]
[tex]\\ \sf\longmapsto <B=180-99[/tex]
[tex]\\ \sf\longmapsto <B=81[/tex]

ANSWER CHOICES 16 17 18 or 19
PLS HELPP
Answer:
16.5
Step-by-step explanation:
Given data to us is ,
20, 15, 14, 16, 17, 12, 20, 22 .Arrange it in ascending order .
= 12 , 14 , 15 , 16 , 17 , 20 , 20 , 22
The middle most observation will be median in case n is odd and average of middlemost observations if n is even , that is n = 8 .
=> Middlemost observations = 16 , 17
=> Mean = 16 + 17 /2 = 33/2 = 16.5
Sum of 2 numbers is 36. The larger is 3 more than twice the
smaller number, Find the smaller number below.
Answer:
11
Step-by-step explanation:
so we just make a system of equations:
x+y=36
say that x is the larger and y is the smaller
x-3=2y
so we can combine the equations and solve for x and y
re-arrange x-3=2y to be x=2y+3
x+y=36
x=2y+3
insert the value for x into x into x+y=36
2y+3+y=36
3y+3=36
y=11
now insert that back into x+y=36
11+x=36
x=25
Out of the two numbers x and y, 11 is the smaller number

In the last year, U.S. car sales of all makes and models have dropped by 16%. Let's say that a car dealer sells 325 cars. If this number drops by 16%, how many cars will the dealer sell then? Round to the nearest whole number.
A 203 cars
B 309 cars
C 273 cars
D 256 cars
Answer:
c. 273 cars
Step-by-step explanation:
First you need to find what 16% of 325 is
325x.16=52
because the number sold dropped by 16% you will subtract 52 from 325
325-52=273
you can also calculate the answer by subtracting 100% by 16%
100%-16%=84%
now you can calculate 84% of 325
325x.84=273

The square pyramid shown below has a base with sides of 10 units. The slant height of the pyramid is 8 units. What is the vertical height, h?
Make a right triangle by using half the base and using the Pythagorean theorem calculate the height.
Height = sqrt(8^2 - 5^2)
Height = sqrt(64 - 25)
Height = sqrt(39)
Height = 6.245 ( Round the answer as needed).
Answer:
6.2
Step-by-step explanation:
We can use the Pythagorean Theorem to find h.
The equation for the Pythagorean Theorem is a^2+b^2=c^2
We see that the hypotenuse of the right triangle is 8. One leg is h. The other leg is 5 , which is half the length of the base.
We have:
a^2+b^2=c^2
5^2+h^2=8^2
25+h^2=64
h^2=39
h= square root of 39
h = 6.244

Find the equation of a line that passes through the point (-2,4) and has a gradient of -3.
Leave your answer in the form
y
=
m
x
+
c
Equation of a line is y = mx +c
m is the gradient, which is given as -3 so now you have:
y = -3x + c
Replace y and x with the given point and solve for c:
4 = -3(-2) + c
Simplify:
4 = 6 + c
Subtract 6 from both sides:
c = -2
The equation becomes:
y = -3x-2
