Answers

Answer 1

Step-by-step explanation:

The approximate tip is - 12.30$

Because bill is 81.79$

and tip - 15%

therefore bill amount divided by 15/100

==> 81.79* 15% is 12.30$

What is mean by Addition?

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

We have to given that;

The average rainfall in inches in Miami from January to May is 1.61, 2.24, 2.99, 3.15, 5.35, and 9.68

While it is 2.24, 2.8, 3.03, 2.05, 2.09, and 6.69 during the same period in Tampa.

Hence, For Miami;

= 1.61 + 2.24 + 2.99 + 3.15 + 5.35 +9.68

= 25.02

For Tampa;

= 2.24 + 2.8 + 3.03 + 2.05 + 2.09 + 6.69

= 18.90

Thus, Find difference as;

= 25.02 - 18.90

= 6.12

Therefore, Miami gets 6.12 more inches of rain.

Here are six number cards -4,-2,-1,5,6,8
arrange the cards into three pairs with the same total

Answers

Answer:

5 and 6 and -1

6 and 8 and -4

5 and 8 and -2 and -1

Step-by-step explanation:

They all add up to 10.

The trick is to first figure out if you can combine 5 6 or 8 together, then use the negative numbers to subtract as needed to reach you number. If you add 5 and 6, that is 11, but -1 can make 10. When you add 8 and 6, that is 14. But good thing you have the -4 to make 10. You start with the smallest number found from adding together two numbers from the positive pile like 5 and 6.

You can make other combinations as well. 11 could work too.

please click heart to give thanks :) c

The pairs of cards are  (-4, 8), (-1, 5) and (-2, 6) respectively.

What is addition?

Addition is a mathematical operation which used to count the things when are together. The addition of two positive integers are greater than both of them while for negative integers it is less than both of them.

Given that,

The different cards having numbers on them are as below,

-4, -2, -1, 5, 6, 8.

In order to select them into three pairs having the same sum make the pair as follows,

Add each positive number to each of the negative numbers and then select the pair of numbers having the same sum.

Thus, it is obtained as,

-4 + 8 = 4

-1 + 5  = 4

-2 + 6 = 4

Hence, the required pairs of cards are (-4, 8), (-1, 5) and (-2, 6) respectively.

There are 150 oranges, apples and pears in a box. The ratio of the number of oranges to the number of apples is 3:5 and the ratio of the number of pears to the number of apples is 2:5. Find the number of pears in the box.

Answers

Answer:

  Pears:  30

Step-by-step explanation:

Constant:

  3x + 5x + 2x = 150

                 10x = 150

                    x = 15  

Multiply ratio with constant from above:

  oranges : apples

       3 * 15 : 5 * 15

            45 : 75       ==>               45 oranges: 75 apples

  pears : apples

   2 * 15 : 5 * 15

        30 : 75          ==>                    30 pears: 75 apples

Check:

45 oranges + 75 apples + 30 pears = 150 fruits

Answer:

∠ WXU = 56°

Step-by-step explanation:

Since WX is a midline then WX and TV are parallel lines, thus

∠ WXU and ∠ TVX are corresponding and congruent, then

8x + 24 = 60 - x ( add x to both sides )

9x + 24 = 60 ( subtract 24 from both sides )

9x = 36 ( divide both sides by 9 )

x = 4

Thus

∠ WXU = 60 - x = 60 - 4 = 56°

You and your friends are having a race, but since you are faster than he is, you decide to give him a head start. He starts 10 m In front if the starting line, while you start on the starting line. You run at 6 meters/ second, while your friend runs at 5.5 meters/ second. After how many seconds will you and your friend be same distance from the starting line?

Answers

Answer:

the number of seconds that you and your friend would be have the similar distance from the starting line is 20 seconds

Step-by-step explanation:

The computation of the number of seconds that you and your friend would be have the similar distance from the starting line is shown below:

As we know that

Speed = Distance ÷ Time

SO,

Time = Distance ÷ speed

= 10 meters ÷ difference in speed

= 10 meters ÷ (6 meters per second - 5.5 meters per second)

= 10 meters ÷ 0.5 meters per second

= 20 seconds

hence, the number of seconds that you and your friend would be have the similar distance from the starting line is 20 seconds

Mathematically, the equation to use is the internal division formula

That will be;

(x,y) = (nx1 + mx2)/m + n , (ny1 + my2)/m + n

where m = 1

n = 4

(x1,y1) = ((-8,8)

(x2,y2) = (7,-7)

Substituting these values, we have

(x,y) = (4(-8) + 1(7))/(1+4) , (4(8) + 1(-7)/(1 + 4)

(x,y) = (-32 + 7)/5, (32 -7)/5

(x,y) = (-25/5), (25/5)

(x,y) = (-5,5)

the angles of a triangle are described as follows: angle a is the largest angle; it measure is twice the measure of Angle b. The measure of Angle C is 10 more than one-third of angle B. Fins the measurements of the three angles in degrees.
(Angles in a triangle add up to 180 degrees.)

Answers

Answer:

Angle A = 102°

Angle B = 51°

Angle C = 27°

Step-by-step explanation:

angle A = 2b

angle B = b

angle C = 1/3 b + 10

Angle A + Angle B + Angle C = 180

2b + b + 1/3 b + 10 = 180

3 1/3 b + 10 = 180

10/3 b = 170

b = 51

a = 2b = 102

c = 1/3 b + 10 = 1/3 (51) + 10 = 17 + 10 = 27
