Use doubles minus one to solve 8+7. Write the number sentence

Answers

Answer 1

Answer:

8+8-1 = 15

Step-by-step explanation:

The doubles minus one is the technique to add two numbers which are consecutive.In this technique you add double the greatest number of the two consecutive and then subtract 1 from the result.

Here we have equation 8+7.

so doubling the greater number (8+8) or (8*2)  gives us 16.

then subtracting 1 from it (16-1) gives us 15

so 15 is our answer.


Answer 2

Using the doubles minus one strategy, the greater value of the expression is doubled and one subtracted from the sum. Hence, we have 8 + 8 - 1 = 15

Given the expression :

8 + 7

The greater value of the two digits is 8

Doubling the greater value : 8 + 8

Subtracting 1 from the sum of the doubled digit :

8 + 8 - 1 = 8 - 7 = 15

Therefore, the result of the expression is 15

a block of gold with a mass of 4,830 kilograms has a volume of 0.25 cubic meters. what is the density of the gold?

Answers

Density = mass / volume
Density = 4,830 / 0.25
Density = 19,320 kg/m

If the volume of a chunk of gold with a mass of 4,830 kg is 0.25 cubic meters. The gold will have a density of 19,320 kg/m.

What is density?

It is defined as the mass-to-volume ratio. The density indicates the object's density and is represented by the symbol. The density is measured in kilograms per cubic meter. While volume is a three-dimensional space enclosed by an object or thing.

It is given that, a block of gold with a mass of 4,830 kilograms has a volume of 0.25 cubic meters.

We have to find the density of the gold.

Density = mass/volume

Density = 4,830 / 0.25

Density = 19,320 kg/m

Thus, if the volume of a chunk of gold with a mass of 4,830 kg is 0.25 cubic meters. The gold will have a density of 19,320 kg/m.

Fran made 18 three point shots and 12 one point shots she had a total of 102 points for the basketball season how many 2 point shots did Fran make for the season? explain your answer

Answers

18 × 3 = 54

Fran made 54 three point shots for the season.

12 × 1 = 12

Fran made 12 one point shots for the season.


Add the three point shots and one point shots together:

54 + 12 = 66

Now, subtract 66 (Number of three point shots and one point shots) from 102 (Total amount of shots)


102 - 66 = 36

36 ÷ 2 = 18


So, Fran made 18 two point shots for the season (Which resulted in 36 points)

Final answer:

The percent increases for the given quantities are 6%, 60%, and 12% respectively. To find these, subtract the original quantity from the new quantity to find the amount of increase, then divide this by the original quantity and multiply by 100.

Explanation:

In order to find the percent increase, you can follow this formula:

Step 1: Subtract the original quantity from the new quantity. This gives you the amount of increase.Step 2: Divide the increase by the original quantity.Step 3: Multiply result by 100 to get the percent increase.

Now, let's solve the questions :

a. Original Quantity: 100, New Quantity: 106

Amount of increase = 106 - 100 = 6

Percent increase = (6/100)*100 = 6%

b. Original Quantity: 10, New Quantity: 16

Amount of increase = 16 - 10 = 6

Percent increase = (6/10)*100 = 60%

What is m∠D ?



Answers

vertical angles are equal

-3x + 58 = x - 2
-3x - x = -2 - 58
-4x = - 60
x = -60/-4
x = 15

m < D = x - 2....15 - 2 = 13 <====
m < C = -3x + 58....-3(15) + 58 = 13 

Answer:

m<D is [tex]13^{0}[/tex]

Step-by-step explanation:

Vertically opposite angles are said to be equal angles, thus;

                   m<C = m<D

So that,

              -3x + 58 = x -2

             -3x - x = -2 -58

               - 4x = - 60

                 x = [tex]\frac{- 60}{- 4}[/tex]

                 x = 15

Thus,

  m< D = x - 2

           = 15 - 2

           = [tex]13^{0}[/tex]

Therefore, m<D is [tex]13^{0}[/tex]
