help me help me help me please​

Answer:

Step-by-step explanation:

33 1/3%=100/3%

A percent as a decimal is percentage divided by 100

(100/3)/100=1/3

Since 1/3 of a number is 24 we can say

n/3=24

n=72

So 24 is 33 1/3% of 72

Answer:

6^4(6^-5)

If base is equal at multiplication we add index.

ex: a^(x)

a = base

x=power = index

6^4 .(6^-5)

6^(4+(-5)

6^(4 - 5)

6^(-1)

1/6

Step-by-step explanation:

Answer:

The correct answers are: 1/6 , 6^-1 ,  1/6^1. B, C and D.

Answer:

5/4 ft

Step-by-step explanation:

Given data

Area= 5/12 square feet

Height= 1/2 ft

Base=????

We know that the area of a triangle is given as

Area= (1/2)B*H

substitute

5/12= 1/2* B* 1/2

5/12= B/4

cross multiply

12B= 20

B= 20/12

B= 5/3

Hence the base is 5/4 ft

Answer:

180- 115= 50+∠2

65-50= ∠2

15°=∠2

Step-by-step explanation:

Answer:

d. 15 degrees

Step-by-step explanation:

You're basically trying to find angle DBC. Adding 115 and 50 will give you 165. This means that angle DBC must be 15, as the angles have to add up to 180. Angle 2 and angle DBC are equal, so angle 2 is 15 degrees.

Answer:

the sand and cement needed is 7.5 kg and 4.5 kg respectively

Step-by-step explanation:

The computation of the sand and cement needed is shown below:

Given that

The mix of sand and cement is 5kg and 3kg i.e. its ratio is 5:3

And there is a 12kg of mix of both things

So individually it required

For sand = 12 × 5 ÷ 8

= 7.5 kg

For cement = 12 × 3 ÷ 8

= 4.5 kg

Hence, the sand and cement needed is 7.5 kg and 4.5 kg respectively

Answer:

Between 1 and 3 seconds

Step-by-step explanation:

There is no change in distance ( change in y ) between 1 and 3, so she wasn't walking during that time

Answer:

B

Step-by-step explanation:

Hey There!

The answer is B because that is where there was no movement on the graph meaning that she stopped walking during that time period.

Answer:

The vertex of the graph is (-3,1)

Step-by-step explanation:

Here, we want to rewrite the given quadratic equation in the vertex form

We have the vertex form as;

y = a(x-h)^2 + k

where the vertex is (h,k)

Now, by completing the square, we have to divide the coefficient of x by 2, then square; after which we add to both sides; prior to this, we have to replace y by 0

Thus, we have it as follows;

x^2 + 6x + 10 = 0

x^2 + 6x + 10 + 3^2 = 3^2

x^2 + 6x + 19 = 9

x^2 + 6x + 9 = 9-10

(x + 3)^2 = -1

(x + 3)^2 + 1 = 0

So we have the vertex as ;

(h,k) = (-3,1)

Answer:

=x+22

-by-step explanation:

Let's simplify step-by-step.

3(x+4)+2(5−x)

Distribute:

=(3)(x)+(3)(4)+(2)(5)+(2)(−x)

=3x+12+10+−2x

Combine Like Terms:

=3x+12+10+−2x

=(3x+−2x)+(12+10)

=x+22

Step-by-step explanation:

7a³ -5b² = ?

when a = 4 and b= 6

7(4)³ -5(6)² = 7(64) - 5(36) = 448 - 180 = 268

Answer:

D

Step-by-step explanation:

They just proved that m< 3 =m< 7 and m< 4=m< 8

So if m< 8=m< 5 and m< 7=m< 6

You can plug in m<5 for m< 8 and m<6 for m<7

Therefore:

m<6=m<3

m<5=m<4

Also, the angles that were proved congruent were vertical angles so the theorem they put works

Answer:

y=42? because 6*2=18 so 21*2=42??

Answer:

7

Step-by-step explanation:

18/6 = 3 so we can assume that for every 3 x there is 1 y. 21/3 = 7

Answer:

For the first part of 4 questions wrong: he would get 42 points

For the second part 48 points

Step-by-step explanation:

For the first part of 4 questions wrong: he would get 42 points because 50 divided by 2 is 25 and 25 minus 4 is 21 and 21 times 2 is 42.

For the last part I'm guessing x = 1 so again 50 divided by 2 is 25 and 25 minus 1 is 24 and 24 times 2 is 48

I think it is right.

Answer: first one 42

The second one is 50-2x

explanation: score with 4 questions wrong

Available points 50. Points lost=points per question x4=2x4=8 final score 50-8=42

Score with x questions wrong: available points 50 points lost=points per questionx4=2*x=2x final score =available points-points lost =50-2x
