Answer:
1: 130
2: 70
Step-by-step explanation:
Supplementary angles add up to equal 180
So to find the measure of the missing angles, we subtract the measure of the known angles from 180
For #1
∠B = 180 - 50
180 - 50 = 130
Hence ∠B = 130
For#2
∠D = 180 - 110
180 - 110 = 70
Hence, ∠D = 70

Step-by-step explanation:
its exponential
count the squares in each one
first is 2 squares
second is 4 squares
third is 8 squares
this is going up exponentially because the first one would be 2^1 the second would be 2^2 and the third would be 2^3

An eagle 311 feet in the air spots its prey on the ground. The angle of depression to its prey is 15°. What is the distance between the eagle and its prey? Round to the nearest foot.
find the distance between the point - 3, 2 and 1 - 1
Answer:
5 units
Step-by-step explanation:
Find the distance between the point - 3, 2 and 1 - 1
Given data
x1= -3
y1= 2
x2= 1
y2= -1
The expression for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
subtitute
d=√((1-(-3))²+(-1-(2))²)
d=√((1+3))²+(-1-2))²)
d=√((4)²+(-3))²)
d=√16+9
d=√25
d=5
Hence the distance between the points is 5 units
Which expression is equivalent to (2^−1⋅2^3) ^−1 ?
a) 16
b) 1/16
c) 1/2
d) 1/4

Suppose you brought 8 oranges and 1 grapefruit for a total price of $4.60. Later that day, you brought 6 oranges and 3 grapefruits for a total price of $4.80.What's the price of each type of fruit.
Answer:
assuming the prices did not change during the day,
8o+g=460
6o+3g=480
18o=900
o=50
g=60
so, oranges cost $0.50, grapefruit cost $0.60
Step-by-step explanation:
do good !
Answer:
oranges $0.5 grapefruit 0.6
Step-by-step explanation:
o = oranges
g= grapefruit
8o +1 g = 4.60
6o+3g= 4.80
Multiply the first by -3
-24o -3g = -13.80
6o +3g = 4.80
ADD BOTH (3g will be cancelled)
-18o = -9.00
o = 9/18 = 0.5
8(0.5) +1g= 4.60
4.00 +g = 4.60
g = 0.60
Which comparison is not correct?
-2 > -7
1 < -9
-3 > -8
6 > 5

PLEASE HELP ASAP BEST ANSWER WILL GET BRAINILEST
Answer:
the answer is c) 9 pounds 7 ounces
Step-by-step explanation:
Because he is gaining 5 ounces a week for 4 weeks
5 times 4= 20 ounces or 1.25 pounds
9 pounds+20 ounces= 9 pounds 7 ounces
Answer:c
Step-by-step explanation:
8lb 3 ounces + 20 ounces (16 ounces=1lb)
Because 20 is greater than 16 we know he should be at least 9 pounds so C
The stem-and-leaf plot below gives the test scores for Mrs. Yang's history classes. There were 15 students in fourth period and 20 in fifth period. Use the plot to answer the questions.
Answers:
a) Fifth Periodb) Fifth Periodc) Range of fourth period = 47, Range of fifth period = 48=========================================================
Explanation:
Part (a)
We are given a two-sided stem-and-leaf plot.
The stems are along the middle column. We have two sets of leaves (one set per class).
The stems are 5,6,7,8,9. The stems represent the tens digit of the test score. Each leaf is a units digit of the test score, so it means each leaf represents a different student (there are 15+20 = 35 leaves total)
In the bottom row we have the stem 9 to represent all the scores in the 90s. In fourth period, only one leaf is shown and that is 8. The score 98 is the only score in the 90s for fourth period. There are more 90s scores for fifth period because we have the three leaves 2, 2, and 9. They correspond to the scores 92, 92, and 99. It's possible to repeat leaves.
Fifth period has more scores in the 90s
---------------------------
Part (b)
The data set for the fourth period class is
{51, 53, 56, 57, 59, 61, 66, 66, 70, 71, 71, 77, 77, 86, 98}
To get this data set, read off each stem with their corresponding leaf. Eg: in the first row we have a stem of 5 pair with the right-most leaf of 1 to form the score 51. You should have 15 scores in this set.
If the data set isn't sorted from smallest to largest, then make sure to do so. After doing that, cross off the first and last items to end up with this smaller set (two less items in it from the previous set listed above)
{53, 56, 57, 59, 61, 66, 66, 70, 71, 71, 77, 77, 86}
Repeat the last step. Cross off the first and last items to get
{56, 57, 59, 61, 66, 66, 70, 71, 71, 77, 77}
Repeat again
{57, 59, 61, 66, 66, 70, 71, 71, 77}
and again
{59, 61, 66, 66, 70, 71, 71}
we keep going until we reach either one or two values left
{61, 66, 66, 70, 71}
{66, 66, 70}
{66}
The last item remaining is 66, which is the middle-most item. This is the median of the fourth period class scores.
We follow the same steps to find the median of the fifth period class.
The original data set for the fifth period class is
{51,53,58,60,60,61,61,61,64,66,67,73,78,79,85,87,88,92,92,99}
After crossing off each pair of outer items, to reduce the set one step at a time, you should end up with these two items in the very middle: {66,67}
The median is the midpoint of those values, so it is (66+67)/2 = 66.5
Or another way you could do it is to note there are 20 scores in the fifth period class, so the middle is between slots 10 and 11. The 10 is from 20/2 = 10. The values in slots 10 and 11 are 66 and 67 respectively, so the midpoint here is 66.5
So we found:
median of fourth period = 66median of fifth period = 66.5We can see that the fifth period class had the higher median score.
---------------------------
Part (c)
Fortunately, this part isn't as lengthy as part (b). To get the range, you subtract the largest and smallest items.
Fourth period range = max - min = 98 - 51 = 47Fifth period range = max - min = 99 - 51 = 48The fifth period has a slightly higher range, so those scores are slightly more spread out. More spread out scores means less consistency.

A wise man once said, "500 reduced by 4 times my age is 188." What is his age?
Answer:
125
Step-by-step explanation:
Answer:
He Is 78 Years Old.
Step-by-step explanation:
a = age
Solve for a in 500 - 4a = 188.
Simplify 500−4a=188.
500−4a=188
500+−4a=188
−4a+500=188
Subtract 500 from both sides.
−4a+500−500=188−500
-4a = -312
Divide both sides by -4.
[tex]\frac{-4a}{-4} =\frac{-312}{-4}[/tex]
a = 78
Answer:
He Is 78 Years Old.
The graph shows the results of tossing two coins 20 times. The two sides of the coin show heads (H) and tails (T). Based on the results, what is the probability that both coins will show heads the next time the coins are tossed? 17 20 Two Coin Toss 8 CON Frequency ONWAY 3 20 HT TH HH IT 3 10
You forgot the picture
The probability that both coins will show heads the next time the coins are tossed is 3/20.
What is probability?Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
From the graph, Total number of outcomes= 7+6+4+3=20
Outcomes for both head =6
Then, P(HH)= 6/20
=3/10
Hence, probability that both coins will show heads is 3/20.

please help me pleaseeeeee
Answer: c=35
D=90
E=55
Step-by-step explanation:
Since d is a right angle it is 90. Take 90 and subtract it from 180 to get 90.Set them equal to 90 so 3x+11+5x+15=90
Simplify
8x+26=90
8x=64
X=8
Now take x and plug it in for each equation
3(8)+11=35
5(8)+15=55
So measured of c is 35
Measure of e is 55
And d is 90
hope this helps
