Answer:
a) 1/4 = 0.25
b) 1/3 ≈ 0.333
c) 23/11 ≈ 2.090
Step-by-step explanation:
To find the fractions with denominators of powers of 10 that correspond to the given fractions, we express each fraction in their decimal form as follows;
a) 1/4 = 1/10×(10/4) = 1/10 × (2 + 2/4)
1/4 - 2/10 = 2/40 = 1/20
1/4 = 1/100 × (100/4) = 1/100 × 25
1/4 = 25/100 = 0.25
Therefore;
1/4 = 25/10² = 0.25
b) 1/3
1/3 = 1/10 × (10/3)
1/3 = 1/10 × (3 + 1/3)
1/3 - 3/10 = 1/30
The 3/10 with a denominator of 10 is closer to 1/3
Similarly, we get;
1/3 = 1/100 × (100/3) = 1/100 × (33 + 1/3)
1/3 - 33/100 = 1/300
The fraction 33/100 with a denominator of 100 is closer to 1/3
We can also get 1/3 - 333/1000 = 1/3000
Therefore; 1/3 ≈ 333/1000 = 0.333
c) 23/11
23/11 = 1/10 × (230/11) = 1/10 × (20 + 10/11)
23/11 - 20/10 = 10/110
23/11 = 1/100 × (2300/11) = 1/100 × (209 + 10/11)
23/11 - 209/100 = 10/1100 = 1/110
23/11 = 1/1000 × (23000/11) = 1/1000 × (2090 + 10/11)
23/11 - 2090/1000 = 10/11000 = 1/1100
Therefore;
23/11 ≈ 2,090/1,000 = 2.09

What does AB equal in this problem? It’s timed
Answer:
For angle B which is 50 degrees,
hypotenuse = AB =?
Adjacent = BC = 2 units......(given)
cos 50 = adjacent / hypotenuse
0.643 = 2 / AB. .....(as cos 50 = 0.643 approx)
AB * 0.643 = 2
AB = 2 / 0.643
AB = 3.11 units(approx)

Use the distributive property to remove the parentheses.
- 4(5u - 3y-1)
Answer:
-20u + 12y + 4
Step-by-step explanation:
We have the equation -4(5u - 3y - 1) and are asked to use the distributive property to remove the parenthesis.
When using the distributive property, you have to multiply the number outside the parenthesis to all numbers inside the parenthesis, do as followed :
-4(5u - 3y - 1)
(5u(-4) -3y(-4) -1(-4))
-20u + 12y + 4

Complete the equation of the line whose y-intercept is (0,5) and slope is -9.
Answer:
-9x + 5
Step-by-step explanation:
Slope Intercept Form = y = mx + b
where x = slope and b = y intercept
We are told that the slope is -9 and the y intercept is at (0,5)
So x = -9 and b = 5
that being said we plug in the values into the equation
Therefore y = -9x + 5 is your answer
Answer:
-9x + 5
Step-by-step explanation:
Complete the equation of the line whose y-intercept is (0,5) and slope is -9.
-9x + 5

The chorus at an elementary school is made up on fifth and sixth graders. This year, the chorus had 12 fifth-grade girls, 9 fifth-grade boys, 14 sixth-grade girls, and 10 sixth-grade boys.
Find the following ratios:
a. The ratio of boys to girls
b. The ratio of fifth graders to sixth graders
c. The ratio of girls to the total number of students in the chorus
Answer:
A: 19:26 B:7:8 C:26:45
Step-by-step explanation:
Question A
First to find the ratio between the boys and girls you would add all of the different groups with boys and girls. This would be done by,
Boys
9+10=19
Girls
12+14=26
Now that you have the total number of boys and girls you make this ratio,
19:26
That is the final answer
Question B
For this it is very similar to the boys to girls ratio. You still add the total on each side and then form a ratio. From before you would start by adding both of the different sides which would be done by,
Fifth Graders
12+9=21
Sixth Graders
14+10=24
Now that you have the total number of both of the different grades you make this ratio,
21:24
You can simplify this by finding the lowest common factor which would be
7:8
Question C
To answer this it is very similar to the first two but instead you will find one group and all of the groups to form the ratio. Now you need to add all of the people in each of the groups.
Girls
12+14=26
All
12+9+14+10=45
Now with the total number of both you will form a ratio
26:45
This is your final answer because you cant simplify this any further
