Answer:
∠ 1 = 130°, ∠ 2 = 50°
Step-by-step explanation:
∠ 1 and 130° are alternate angles and congruent, so
∠ 1 = 130°
∠ 2 and 130° are same- side interior angles and are supplementary, so
∠ 2 + 130° = 180° ( subtract 130° from both sides )
∠ 2 = 50°
Answer: it is 130 and 50
Step-by-step explanation: Honestly, they already gave one angle so it is a HUGE giveaway. 180-130 is 50, so the answers are 130 and 50.
The probability for success of an event is P(A), and the probability of success of a second, independent event is P(B). What is the probability of both events occurring, in that order?
P(A) • P(B)
P(A + B)
P(A x B)
P(A) + P(B)
Given:
The probability for success of an event is P(A)
The probability of success of a second, independent event is P(B).
To find:
The probability of both events occurring, in that order.
Solution:
If A and B are two independent events, then
[tex]P(A\cap B)=P(A)\cdot P(B)[/tex]
It is given that,
The probability for success of an event is P(A)
The probability of success of a second, independent event is P(B).
Since A and B both are independent event and we need to find the probability of both events occurring, in that order, i.e., [tex]P(A\cap B)[/tex], therefore [tex]P(A\cap B)=P(A)\cdot P(B)[/tex].
Hence, the correct option is A.
When building a house, the number of days required to build varies inversely with with the number of workers. One house was built in 55 days by 8 workers. How many days would it take to build a similar house with 40 workers?
Answer:
See below
Step-by-step explanation:
We can make a the number of days and y the number of workers
Since we were told there is an inverse relationship between the days required to build the house and the number of workers required, then,
The equation would be
y = k/x
Here, y is inversely proportional to x and k is the constant proportionality
So, out required equation would be
a = k/n
Fixing the values, we'll have
55 = k/8
k = 55 × 8
k = 440
The number of days required to build a similar house with 5 workers will now be
= 440/5
= 88 days

The ratio of cups of orange juice concentrate to water in a punch recipe is 2 : 5. If Geoffrey used 20 cups of water, how many cups of orange juice concentrate did he use?
Answer: 8 cups
Step-by-step explanation:
Let the cups of orange juice concentrate that he used be represented by x.
Therefore, based on the information, we can form an equation which will be:
2/5 = x/20
Cross multiply
5 × x = 2 × 20
5x = 40
x = 40/5
x = 8
Therefore, he used 8 cups of orange juice concentrate.
The St. Louis Cardinals defeated the Texas Rangers in the 2011 World Series in a thrilling 7game series. The matrices below show the statistics for runs, hits, and errors for each team in each game.
Which team had the most total runs
Which team had the most total hits
Answer:
The St. Louis Cardinals had the most total runs
The Texas Rangers had the most total hits
Step-by-step explanation:
From the given matrices, we have;
The total runs made by the St. Louis Cardinals is found by adding the runs obtained in each of the seven games as follows;
Total runs by St. Louis = 3 + 1 + 16 + 0 + 2 + 10 + 6 = 38
Similarly the total hits by the St. Louis Cardinals is given as follows;
Total hits by St. Louis = 6 + 6 + 15 + 2 + 7 + 13 + 7 = 56
For Texas Rangers, we have;
Total runs by Texas Rangers = 2 + 2 + 7 + 4 + 4 + 9 + 2 = 30
Total hits by the Texas Rangers = 6 + 5 + 13 + 6 + 9 + 15 + 6 = 60
Therefore, we have;
The St. Louis Cardinals has the most total runs with 38 runs which is more when compared to the Texas Rangers that have 30 runs
The Texas Rangers has the most total hits with 60 hits compared to the St. Louis Cardinals that have 56.

Answer:
2x+8
Step-by-step explanation:
So when they say a number, they mean a unknown value.
We can use a variable as this unknown value. In this situration we can call it x.
This phase says "twice a number" or "twice x". This can be though of as 2x.
next it says this number is increased by 8. When they say increased they meanm added to.
So 8 is added to 2x. Or 2x + 8
So its the second answer, 2x+8.
Hope this helps!

Rewrite 5 1/4 as an improper fraction:
Multiply the whole number by the denominator of the fraction then add the numerator of the fraction and put over the denominator:
5 x 4 = 20 + 1 = 21
5 1/4 = 21/4
Ow divide the total amount (21/4) by the amount in each bag (5/8)
21/4 / 5/8
When dividing by a fraction flip the second fraction over and then multiply straight across:
21/4 / 5/8 = 21/4 x 8/5 = (21 x 8) / (4 x5) = 168/20 = 8 8/20 = 8 2/5 bags
He can fill 8 full bags and 2/5 of a other bag

hey cutie pls help me !! brainilist will be given !!
Answer:
Part a.
An angle bisector divides the angle into two congruent angles.
m<FGH = m<HGI
2x - 4 = 3x - 22
Subtract 2x from both sides. Add 22 to both sides.
18 = x
x = 18
Now that we know x = 18,
m<FGH = 2x - 4 = 2(18) - 4 = 36 - 4 = 32
m<FGH = 32
Part b.
m<HGI = 3x - 22 = 3(18) - 22 = 54 - 22 = 32
m<HGI = 32
Part c.
m<FGI = m<FGH + m<HGI = 32 + 32 = 64
m<FGI = 64

23 travelers forest 63 piles of plantains containing the same number of plantains and a remaining pile containing 7 plantains. They divided the plantains equally. What is the least number of plantains that each traveler got?
Answer:
14 plantains
Step-by-step explanation:
Given
[tex]x \to[/tex] plantain in a pile
[tex]y \to[/tex] plantain received by each
[tex]n = 23[/tex] travelers
Required
The least value of y
Note that:
- There are x plantains in 1 pile, so there will be 63x in 63 piles
- The number of plantains shared is: 7 to 63x (7 represents the single plantain)
- 1 traveler gets y plantains, so 23y will receive 7 + 63x plantains
So, the equation is:
[tex]23y = 7 + 63x[/tex]
Make y the subject
[tex]y = \frac{7 + 63x}{23}[/tex]
The values of x and y must be integer and these values must be greater than 0.
Using trial by error method, we test the values of x starting from 1;
So, we have:
[tex]x = 1 \to y = \frac{7 + 63 * 1}{23} = \frac{70}{23} = 3.04[/tex]
[tex]x = 2 \to y = \frac{7 + 63 * 2}{23} = \frac{133}{23} = 5.78[/tex]
[tex]x = 3 \to y = \frac{7 + 63 * 3}{23} = \frac{133}{23} = 8.52[/tex]
[tex]x = 4 \to y = \frac{7 + 63 * 4}{23} = \frac{259}{23} = 11.26[/tex]
[tex]x = 5 \to y = \frac{7 + 63 * 5}{23} = \frac{322}{23} = 14[/tex]
So, the smallest values of x and y that satisfy the equation is:
[tex](x,y)=(5,14)[/tex]
Hence, the least number of plantain each traveler got is 14

Probability is the chance of an event to occur from a total number of outcomes.
The correct interpretation of this probability can be:
If you take a very large sample of the times the repair person is scheduled to arrive, the person will be on time approximately 65% of the time.
What is probability?Probability is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
The probability that an appliance repair person arrives within the window of time scheduled by the company is 0.65.
This means,
The probability that an appliance repair person will arrive at the scheduled time.
= 0.65
= 65/100
This can also be interpreted as out of 100 times 65 times will be on time.
We see that,
The correct interpretation of this probability can be:
If you take a very large sample of the times the repair person is scheduled to arrive, the person will be on time approximately 65% of the time.
Thus,
The correct interpretation of this probability can be:
If you take a very large sample of the times the repair person is scheduled to arrive, the person will be on time approximately 65% of the time.
