Answer:
3/8 yards
Step-by-step explanation:
3/4 yard tall and 1/2 yard wide

i need some help with this
Answer:
1200 square inches
Step-by-step explanation:
First find area of rectangle which is length x width
20 x 30 = 600
then to find area of the two right triangles multiply the legs then divide by 2
20 x 30 = 600
600/2 = 300
since there is 2 multiply 300 by 2
600
then add everything together
600+600 = 1200

Ann runs a day care center. Of the last 18 children to enroll at the day care center, 8 of them have been elementary school students. Considering this data, how many of the next 9 children to enroll should you expect to be elementary school students?

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If 8 out of the last 18 children to enroll at the daycare center were elementary school students,
We can find the fraction of elementary school students in that group by dividing the number of elementary school students by the total number of children:
= 8/18
= 4/9
This means that 4 out of every 9 children enrolled were elementary school students.
If we want to predict how many of the next 9 children to enroll will be elementary school students,
We can use this ratio:
4/9 of 9 children
= (4/9) x 9
= 4
Therefore,
We would expect that 4 of the next 9 children to enroll will be elementary school students.

For which weight of clothing is the ratio of weight to dye different from the other ratios?
21 pounds
42 pounds
84 pounds
105 pounds
Answer: The answer is 42
Step-by-step explanation:
I did the test too :)
The weight of clothing for which the ratio of weight to dye is different from the other ratios is 42 pounds.
To determine which weight of clothing has a ratio of weight to dye different from the other ratios, we need to compare the ratios for each weight.
Let's calculate the ratios for each weight of clothing by dividing the weight of clothing (in pounds) by the cups of dye:
For 21 pounds of clothing: 21 pounds / 3 cups = 7 pounds per cup
For 42 pounds of clothing: 42 pounds / 9 cups = 4.67 pounds per cup
For 84 pounds of clothing: 84 pounds / 12 cups = 7 pounds per cup
For 105 pounds of clothing: 105 pounds / 15 cups = 7 pounds per cup
From the calculations, we can see that for weights of 21 pounds, 84 pounds, and 105 pounds of clothing, the ratios of weight to dye are the same, which is 7 pounds per cup. However, the ratio for 42 pounds of clothing is different, which is 4.67 pounds per cup.
Therefore, the weight of clothing for which the ratio of weight to dye is different from the other ratios is 42 pounds.

7) Celia is scheduled to work a total of 20 hours this week. So far she has worked 75% of her hours. How many hours has she worked so far this week? *
Answer:
Number of hours she worked so far = 15 hours
Step-by-step explanation:
Total hours scheduled to work this week = 20 hours
Percentage of Hours worked so far = 75%
How many hours has she worked so far this week?
Number of hours she worked so far = 75% of 20 hours
= 75/100 * 20
= 0.75 * 20
= 15
Number of hours she worked so far = 15 hours

Answer:
7. 80 miles
8. F
Step-by-step explanation:
7. Jorge leaves 2 hours early, and is going 20 miles per hour. So before Marcos starts going, Jorge has gone 40 miles (2*20). Then, 1 hour later, Jorge is at 60 miles and Marcos is at 40 (because he goes 40 miles per hour in his car). Another hour later, Jorge is at 80 (60+20) and Marcos is at 80 as well (40 + 40). They will both have gone 80 miles when Marcus catches up.
8. You want to get a isolated.
A = h/2(a + b)
First, multiply both sides of the equation by the reciprocal of h/2.
2A/h = a + b
Then, subtract b from both sides.
2A-b/h = a
After how many years will an investment of $100 compounded quarterly at 6% annually be worth $450? (round to the nearest year)
Answer:
The investment will be worth $450 after 25.255 years which is about 25 years and 3 months.
Step-by-step explanation:
You have to use the following formula to calculate the number of years:
t=ln(A/P) / n(ln(1 + r/n)), where:
t=time in years
A=Accrued amount=450
P=Principal amount=100
n=number of compounding periods per time period=4
r=interest rate=0.06
Now, you can replace the values in the formula:
t=ln(450/100)/4(ln(1+(0.06/4)))
t=ln(4.5)/4(ln(1.015))
t=1.50/0.059
t=25.255
According to this, the answer is that the investment will be worth $450 after 25.255 years which is about 25 years and 3 months.
If line segment AB,A(9,3) and B(-6,-9), what scale factor was used to dilate if new line is at A'(3,1) and B'(-2,-3)?
Answer:
The scale factor is 1/3
Step-by-step explanation:
Here, we want to get the scale factor used in dilating the original segment
As we can see;
(9,3) turned to (3,1)
looking at this , we can see that both coordinate values were divided by 3
So what this mean is that the particular scale factor used is reduction by 1/3
This is the case with the other point as (-6,-9) turned to (-2,-3)
Find the gradient of the line segment between the points (3,2) and (2,5).
The answer is -3.

The eastbound train travels 10 miles per hour faster than the westbound train. After 2 hours, they are 232 miles apart. At what speeds are the two trains traveling?
Answer:
48,58
Step-by-step explanation:
Let The speed of the west bound train be x
Let the east bound train be x+10
The speeds can be calculated as follows
2(2x+10)= 232
4x + 40= 232
4x= 232-40
4x= 192
x= 192/4
= 48
Hence the speedof the west bound train is 48
The speed of the east bound train is 48+10

Can you give me an example on why it’s not foolish to fear ?
Answer:
It is not foolish to fear—it is a matter of survival. The physical responses we have to objects or situations that we fear are often grouped together and characterized as a “fight or flight” instinct. Something alarms you, and instantly your brain causes a number of chemicals to be released into your bloodstream.
Answer:
Fear is already a part of human nature. In fact, fear is used as a defense mechanism of our ancestors long time ago. They used to live on caves, jungles, and not so sturdy shelters that would make them vulnerable enough to different predators. Thus having the feeling of fear saves them by backing down and to retreat unto safer places. Therefore I can say that it's not foolish to fear since it's already a part of us human beings. Even the bravest persons in the world have their own fears too. We can't just separate it from ourselves and let's just embrace it and try to do something to lessen it.
