Bianca set the thermostat in her house to 87°F, which was 13° warmer than the temperature outside. What temperature was it outside?

Confused.

Answers

Answer: 74 degrees Fahrenheit  

Step-by-step explanation: the temperature outside was 13 degrees lower than 87 degrees, so  87 - 13 = 74

Answer:

74 degrees F

Step-by-step explanation:

Subtract the 87 - 13

This is because there are +13 degrees more than outside. So if you add 74 + 13 that were added by the thermostat, you get 87 degrees. Does it make sense?

Just subtract :)

Mary used one big bag of flour. She baked four loaves of bread.​ Then, she used the remaining flour to make 48 muffins. How much flour was in the bag when Mary​ began? Plz help!!!! I have 20 minutes left

Answers

Answer is 11.

Step-by-step explanation:

Maria used two loaves of bread , One loaf is equal=2 1/4 cups so two becomes 2 ×2 1/4= 9/2

Maria makes the remaing 48 muffins of the flour left so,

One muffin is equal 3 1/4 cups so two becomes 2×3 1/4=13/2

Add both of them

9/2+13/2=11

Can someone write the process and solution please?

Answers

Answer:

A

Step-by-step explanation:

We can get this by simplifying the inequalities

3(x-4) ≤ 18

3x - 12 ≤ 18

3x ≤ 18 + 12

3x ≤ 30

x ≤ 30/3

x ≤ 10

Secondly;

2(x-1) ≥ 6

2x - 2 ≥ 6

2x ≥ 6 + 2

2x ≥ 8

x ≥ 4

So the possible answer that fits both cases is 9

12 won’t work as it is not less than 10; we need an answer that is less than 10 to satisfy the first inequality

Avery is making a necklace for her mothers birthday. She uses 1 1/20 strings of black beads and 1 4/5 more strings of gray beads than black beads. How many strings of gray beads did she use?

.

Answers

Answer:

She used 2 17/20 strings of grey beads

Step-by-step explanation:

Here, we want to know the number of grey beads used

To calculate this, we simply add up the black beads number with the number of grey beads

Mathematically, that will be;

1 1/20 + 1 4/5

= 21/20 + 9/5

= (21 + 36)/20

= 57/20 = 2 17/20

Choose the number that is 5 more than a square number.

Answers

5 more than a square number would be 21 which is 5 more than 16 (the square of 4)

Answer:

21

Step-by-step explanation:

this requires practical assumption.

take 9 for example

5 more than 9 means 9 - 5 = 4

4 is a square number

21 = 21 - 5 = 16

16 is a square number

34 = 34 - 5 = 29

29 is not a square number

35 = 35 - 5 = 30

30 is not a square number

65 = 65 - 5 = 60

60 is not a square number

76 = 76 - 5 = 71

Step-by-step explanation:

There are no angles involved in the proof, so the SAS claims do not apply.

__

The symmetric property says ...

  if A ≅ B, then B ≅ A

The reflexive property says ...

  A ≅ A

In this case, the reflexive property is the one being invoked in the statement ...

  AC ≅ AC

That, together with the claims of line 3 concludes the claim that all three sides are congruent to their corresponding counterparts. Hence the SSS postulate applies.

1760 upper primary pupils took part in a sports meet in 2014. This was decreased of 20% when compared to 2015. The number of the upper primary pupils who took part in 2016 increased by 5% when compared to 2015. How many upper primary pupils took part in the sports meet in 2016?

Answers

Answer:

Number of upper primary pupils who took part in the sports meet in 2016 is 1478.

Step-by-step explanation:

Total number of upper primary pupils who took part in the sports meet in 2014 is 1760. It was decreased of 20% compared to 2015.

So that,

20% of 1760 = [tex]\frac{20}{100}[/tex] x 1760

                    = 0.2 x 1760

                    = 352

Number of upper primary pupils who took part in the sports meet in 2015 = 1760 - 352

                   = 1408

Also,

5% of 1408 = [tex]\frac{5}{100}[/tex] x 1408

                  = 0.05 x 1408

                  = 70.4

Number of upper primary pupils who took part in the sports meet in 2016 = 1408 + 70.4

                           = 1478.4

With an increase of 5% compared to 2015, the number of upper primary pupils who took part in the sports meet in 2016 is 1478.
