Answer 1

Answer:

 57/10 or 5 7/10

Step-by-step explanation:

Simplify the following:

3 + 1/5 + 7/2 - 1

Put 3 + 1/5 + 7/2 - 1 over the common denominator 10. 3 + 1/5 + 7/2 - 1 = (10×3)/10 + 2/10 + (5×7)/10 - 10/10:

(10×3)/10 + 2/10 + (5×7)/10 - 10/10

10×3 = 30:

30/10 + 2/10 + (5×7)/10 - 10/10

5×7 = 35:

30/10 + 2/10 + 35/10 - 10/10

30/10 + 2/10 + 35/10 - 10/10 = (30 + 2 + 35 - 10)/10:

(30 + 2 + 35 - 10)/10

| 3 | 5

| 3 | 0

+ | | 2

| 6 | 7:

(67 - 10)/10

| 6 | 7

- | 1 | 0

| 5 | 7:

Answer:  57/10 or 5 7/10

Answer 2
So the answer would be 57/10

change the 6 ito - 6 by turning to left side then you will have -3 -6 now you can add them (- + -) is + so you can add them the sign of 6 is greater so the answer is -9

p = - 9

The 6 turns into - 6. Take - 3 and subtract it by - 6 and you will get - 9 as your answer.

okay so we know that a circle is 360°

the one angle is 135 degrees and to find the other one we can just subtract 360 - 135

the other angle is 225°



we can set it up as:

12 yd x
——— = ——-
225 135


to find x, cross multiply 135 and 12 which gives you 1,620
1,620 / 225 = 7.2

the other angle is 7.2 yards!

31.4 ft squared
125.6 ft squared
314 ft squared
1,256 ft squared

Answers

Answer:

314 ft squared

Step-by-step explanation:

A = πr^2 = π · 102 ≈ 314.15927

Answer:

314.159265359 ft squared or 314.16 ft squared rounded to the hundredths place. The closest result is option C.

Step-by-step explanation:

The formula for finding the area of a circle is A=π×r^2.

Step 1: Find the radius which is half of the diameter. In this case, the radius is 10 feet.

Step 2: Square the radius that you found. In this case, the number will be 100ft or 10^2.

Step 3: Multiple this number by π, or 3.14 if your teacher allows it. So in this case, 100×π=314.159265359 or 314.16 rounded to the hundredths place. If you use 3.14... the answer is 314.

Step 4: You've got your answer. Hope this helps!

C. 4/3m=180

D. 4/3m=90

Answers

Answer:

d

Step-by-step explanation:

the answer is d. complementary angles are always angles that add up to 90 degrees. so, you can eliminate answer A and C. the question mentions a fraction which is 1/3 so u can assume the answer should have a fraction aswell. That eliminates answer B so you're left with C

the answer is $102.20 because first lots are 8 of the and second lot are 7 of them,so 7×14.60=102.20

Answer:

Question 2: $102.20 collected second day

Question 1: x[tex]\leq[/tex]-5

Step-by-step explanation:

Question 2:

We know that there are 15 members total.  The first day 8 members paid and the remaining paid on the second day.  To find the second day total just subtract first day from total members and that leaves the number who paid on second day.

15-8=7

So now we know 8 paid on 1st day and 7 on 2nd day.  To find the total paid on either day just multiply cost of dues by number who paid that day.

14.60*7=102.2

Question 1:

First let's make an equation with info from picture...

In first box there are 4 of the rectangles and the Key tells us they represent x.  We also have 12 white squares the Key tells us represents 1 each.  So first box is...

4x+12

Second box has 8 shaded squares that Key tells us represents -1 each.  So second box is...

-8

Our equation to solve with these values would be...

4x+12[tex]\leq[/tex]-8

4x[tex]\leq[/tex]-20
