C) 30, 60, 90 because right off the bat, the largest angle is 90 degrees and it is the ONLY answer in which it’s other 2 angles are summed up to equal to it. And the rest of the facts match up. 60 degrees is twice as 30

PLS HELP I NEED THIS DONE NOW AND PLS EXPLAIN
Minchanka [31]

Answer:

The answer is 15.

Step-by-step explanation:

Don't forget about the A and H equaling 5. That is there to throw you off. A and B equals 8. Right? Well that's the length. The the A and E is 3. Right? Well that's the height. what you do is cut the triangular prism in half and you end up with a triangular prism with a height of 5. Then you multiply that with 1.5. You get 1.5 by dividing 3 by 2.  You then get 7.5. Now multiply that with 2. Your final answer is 14.

1.2÷0.375−0.2/6 4/25 ÷15 2/5 +0.8 = 0.016÷0.12+0.7/x <br><br> pls solve for x with explaination
masha68 [24]

The value of x is 0.1810

Step-by-step explanation:

Given the equation as;

1.2÷0.375 - 0.2/6 * 4/25 ÷ 15 2/5 +0.8 = 0.016 ÷ 0.12 +0.7/x

This can be written as;

1.2÷0.375-0.4/75÷77/5+0.8=0.016÷0.12+0.7/x

Apply BODMAS style (Brackets, Of, Division,Multiplication,Addition and Subtraction) where in this case you start with division

(1.2÷0.375)-(0.4÷75) ÷ 77/5 +0.8 = (0.016÷0.12) +0.7/x

3.2 - 0.00533 ÷ 15.4 +0.8 =0.133+0.7/x

3.2-0.0003461+0.8=0.133+0.7/x---------------apply addition

3.2+0.8 -0.0003461-0.133=0.7/x

4-0.0003461-0.133=0.7/x

3.867=0.7/x

0.7/3.867=x

0.1810=x

6. Charlie can spend up to $8 on lunch. He wants to buy a tuna sandwich, a bottle of
PilotLPTM [1.2K]

Answer:

The maximum number of pounds of potato salad that Charlie can buy is 0.375

Step-by-step explanation:

see the attached figure to better understand the problem

Let

a ----> the cost of one tuna sandwich

b ----> the cost of a bottle of apple juice

c ----> the cost per pound of potato salad

x ----> pounds of potato salad

we have

a=\$4.25

b=\$2.25

c=\$4.00/lb

we know that

He wants to buy a tuna sandwich, a bottle of  apple juice, and x pounds of potato salad and can spend up to $8

The inequality that represent this situation is

a+b+cx \leq 8

substitute the given values

4.25+2.25+4.00x \leq 8

Solve for x

Combine like terms

6.50+4.00x \leq 8

Subtract 6.50 both sides

4.00x \leq 8-6.50

4.00x \leq 1.50

Divide by 4 both sides

x \leq 1.50/4.00

x \leq 0.375\ lbs

therefore

The maximum number of pounds of potato salad that Charlie can buy is 0.375

How do I calculate these division facts and what’s the answer 63 ÷ 7 56 ÷ 7
bixtya [17]

Answer:

63 divided by 7 is 9

56 divided by 7 is 8

Step-by-step explanation:

I don't really know how to explain it, because it's kind of complicated to do it how I answered it. I will try, but what you do is write out the equation using the little line division thing with the divisor and the dividend. First for 63 divided by 7, how many times can 7 go into 6? 0, so put a 0 on top of the 6. Then, minus 6 by 0, which is 6. Then, drop down the 3 in the ones place to where the difference of the subtraction problem is, which of 6. Then, we try to find a product that is 63 or close to 63 in a multiplication problem, and one of those factors has to be 7. 7 x 9 = 63, so put a 9 on top of the 3 at the beginning and minus 63 - 63, which is 0, meaning it has no remainder. Very hard to explain digitally, look up a video for help.

y = 2(19) + 15
