Answer: Buthaina bought 11 books.
Step-by-step explanation:
First, write your givens.
1 book costs $6.00
A discount of $8.00
Total AFTER discount $58.00
Add the discount to your total= 58.00+8.00=66.00
Take your total BEFORE the discount (66.00) and divide it by 6.
66/6= 11.

What is the measure of Zx in the diagram shown below?
A
23°
B
33°
С
113°
157°
Answer:
Since that is a right angle it is going to equal 90 degrees. Since you know that the first angle is 67 degrees subtract 67 from 90 and get 23 degrees.

11) Which of the following is zero of the polynomial x^3+x^2+x+1
1
-1
both options 1 and 2
None
please answer
Answer:
The correct answer is option 2: -1
Step-by-step explanation:
In order to check if a number is zero of a function or not, the numer is put into the function in plave of variable. If the answer is zero thent he number is zero of the function and if the answer is not zero the given number is not a zero of the function.
Given function is:
[tex]x^3+x^2+x+1[/tex]
Putting x=1
[tex]=(1)^3+(1)^2+1+1\\=1+1+1+1\\=4[/tex]
1 is not zero of the function.
Putting x = -1
[tex]=(-1)^3+(-1)^2+(-1)+1\\=-1+1-1+1\\=0[/tex]
-1 is zero of the given function.
Hence,
The correct answer is option 2: -1

determine the measure of angle a. PLEASE HELP ASAP!
a.64 degrees
b.45 degrees
c.88 degrees
d.42 degrees
Answer:
D
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle will always total 180.
Therefore:
[tex](9x+6)+(74)+(16x)=180\\[/tex]
Let’s solve for x:
Combine LIke Terms:
[tex](9x+16x)+(74+6)=180[/tex]
Add:
[tex]25x+80=180[/tex]
Subtract 80 from both sides:
[tex]25x=100[/tex]
Divide both sides by 25:
[tex]x=4[/tex]
Therefore, the value of x is 4.
Now, to find A, we can substitute it for A.
A is measured by:
[tex]\angle A=9x+6[/tex]
Substitute 4 for x and evaluate:
[tex]\angle A=9(4)+6=36+6=42\textdegree[/tex]
Hence, our answer is D.

Please help! I’ll give brainliest!!
Answer:
110
Step-by-step explanation:
The answer is 110 degrees. The reason is hard to put into simple language.
If the central angle and the acute angle hitting the circumference share the same end points, then the central angle is double the arc whose vertex is on the circumference.
Read that sentence a couple of times. I don't know how to make it simpler.
The arc angle and the central angle both have B and C as their end points.
The arc angle is on the circumference of the circle. The vertex (A) of BAC is on the circumference. If mine is the only answer, wait a few days before awarding a Brainliest. A thanks will do.

Carlos is making party favors. Every bag has exactly the same treats in it. Carlos has 96 granola bars and 64 popcorn balls. What is the greatest number of party favors Carlos can make?
Answer:
32
Step-by-step explanation:
Given that:
Number of granola bars = 96
Number of popcorn balls = 64
Greatest number of party favors that can be made from granola bars and popcorn balls ;
Obtain the greatest common factor of both 96 and 64
Factors of :
96 : 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
64 : 2, 4, 8, 16,32
greatest common factor is 32,
Hence, greatest number of party favors that can be made is 32

Suppose a bird is 500 feet above the ground. It descends at a steady rate. After 10 seconds, it is 250 feet above the ground.
a) Write an equation that gives the height of the bird as a function of time. Be sure to define your variables!
b) After how many seconds will the bird land on the ground?
Answer:
500-10x=250
x=how much the bird descended in a second
the bird will land on the ground in another 10 seconds.
Step-by-step explanation:
the bird will land on the ground in 10 seconds since it descended 250 ft in 10 seconds so that is 25 ft per second. then do 250/25 and you get 10. that is how you know the bird will land on the ground in 10 seconds.
Answer:
a) [tex]h(t)=500-25t[/tex]
b) [tex]t=20[/tex]
Step-by-step explanation:
a)
Let [tex]h[/tex] = height above ground
Let [tex]t[/tex] = time
Because the bird descended down to 250 feet in 10 seconds with a steady rate, that means it descends 25 feet per second.
∴ [tex]h(t) = 500-25t[/tex]
b)
To find the time it takes until the bird reaches the ground, [tex]h[/tex] must equal [tex]0[/tex]:
[tex]0=500-25t[/tex]
[tex]25t=500[/tex]
[tex]t=20[/tex]
∴ It takes 20 seconds for the bird to reach the ground.
The measure of angle D is 47 degrees and the measure of angle C is 57 degrees. What is the
measure of angle A?
47
57
76
104
Answer:
D. 104º
Step-by-step explanation:
So the inside of a triangle is equal to 180º and we already know two of the angles.
D = 47º
C = 57º
47 + 57 = 104
To solve angles A and B, we know that a straight line is 180º and we can figure out the angle of B because now all we have to do is subtract 104 from 180.
180 - 104 = 76, B = 76º
Because we know that a straight line is 180º and we already have the measure of angle B, all we have to do now is subtract 76 from 180.
180 - 76 = 104º

Bill's Bargains sells 16 ounces of Circle O's cereal for $3.36. Debbie's Deals sells 40 ounces of Circle O's cereal for $7.60. Which store as the better deal?
Answer:
Debbie's Deals has the better deal with a price of $0.19 per ounce compared to Bill's Bargains at $0.21 per ounce.
Step-by-step explanation:
Divide $3.36 by 16 = $0.21
Divide $7.60 by 40 = $0.19
Debbie's Deals sells the Circle O's cereal for a cheaper per ounce price thus it's the better price and the better deal.
Good luck!
What is the slope of the line that passes through the points (-6, -10) and (3,-13)? Write your answer in simplest form.

Ashley grew 10 flowers with 2 seed packets. How many seed packets does Ashley need to have a total of 20 flowers in her garden? Solve using unit rates.
Answer:
4
Step-by-step explanation:
10 flowers = 2 packets
20 is 10 multiplied by 2 so multiply the number of seed packets by 2

twice the greater of two integers odd integers is 13 less than 3 times the lesser number. find the integers. what are the integers to this riddle?
Answer:
17 and 19
Step-by-step explanation:
n= lesser integer n+2= greater integer
2(n+2) = 3n -13
2n +4 = 3n-13
n= 17
lesser number =17
The other greater number = 19 (they are odd,so skipping 18)
19 x 2 = 38
17x3 - 13 =51-13 = 38
