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]
[tex]\\ \sf\longmapsto <B=<D=81°[/tex]
Find the area of the figure. Use 3.14 for pie . Round your answer to the nearest tenth.
Answer:
538.3
Step-by-step explanation:
First of all find the area of the rectangle
L*W
15*30
450
Now find the area of semi circle
1/2[tex]\pi r^{2}[/tex]
Since radius is half a diameter divided 15 by 2=7.5
1/2[tex]\pi 7.5^{2}[/tex] 7.5 times 7.5= 56.25
1/2*3.14*56.25
56 times 3.14 is 176.625 now multiply 176.625 by 1/2
Answer is 88.3125
Now add 450 to 88.3125
Final answer: 538.3125
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

whats the median of (20, 15, 14, 16, 17, 12, 20, 22)
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
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

Transformation of parent Functions I need help
Answer:
D: ∛(¼(x + 5))
Step-by-step explanation:
The parent function is;
f(x) = ∛x
A horizontal stretch multiplying by ¼ means that our function is now;
f(x/4) = ∛(x/4)
Now shifting to the left by 5 units denotes;
f(x + 5) = ∛((x + 5)/4)
Or expressed as; ∛(¼(x + 5))

A business owner wants to know if it will be profitable to open a new coffee shop in a nearby town.In towns where the shop has been successful,the shop name is recognizable to people 53% of the time .He survey random sample of 12 residents of the town. Find the probability that among these 12 surveyed residents, none of them have ever heard of the coffee shop
Answer:
0.000116
Step-by-step explanation:
Using the binomial probability relation :
Probability of success, p = 0.53
1 - p = 0.47
Number surveyed, n = 12
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Probability that none has heard of the coffee shop :
P(x = 0) = 12C0 * 0.53^0 * 0.47^12
P(x = 0) = 0.000116

PLZZ help
Answer:
s = 6 feet
Step-by-step explanation:
Given that,
The volume of the cube, V = 216 feet³
We need to find the side length for the cubical box. We know that the volume of the cube is given by :
[tex]V=s^3[/tex], s is the side length of the box.
So,
[tex]s={V}^{1/3}\\\\s={216}^{1/3}\\\\s=6\ feet[/tex]
