Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

Just multiply 3, 4 and 5 together. You'll get 60.

Answer 2

Answer:

Answer:

Step-by-step explanation:

cake method:

arrange 3,4and 5 inside your"cake"

ask your self do 3,4 and 5 have any common factors

if not factor out one of the numbers

OBJECTIVE IS TO GET ALL NUMBERS TO 1 and multiply all factors once they do

3 goes into 3 once

3 goes into 4 0 times

and 3 goes into 5 0 times

next take 4 and do the same

take 5 and do the same as well

the factors u should be left with are 3,4,5

now multiply these

3*4*5=60

lcm=60

The figure shows two right trapezoids. Trapezoid A B C D has right angles at B and C. Angle B is adjacent to the shorter parallel side. Angle C is adjacent to the longer parallel side. Angle A is obtuse. Angle D is acute. Sides A B and C D are parallel. The sides in order of length from shortest to longest are B C, A D, A B, and C D. Trapezoid R S P Q has right angles at S and P. Angle S is adjacent to the shorter parallel side. Angle P is adjacent to the longer parallel side. Angle R is obtuse. Angle Q is acute. Sides R S and P Q are parallel. The sides in order of length from shortest to longest are S R, R Q, R S, and P Q.The two figures shown above are congruent. Identify the corresponding sides and angles.

please help this is all they gave me

Answers

Answer:

In the trapezoids ABCD and RSPQ,

Angles A, B, C and D are corresponding to the angles R, S, P and Q respectively,

Also, the sides AB, BC, CD and DA are corresponding to the sides RS, SP, PQ and QR respectively.

Since, when two figures are congruent to each other then their corresponding sides and angles are also congruent.

Here, trapezoids ABCD and RSPQ are congruent.

Therefore, AB≅RS, AB≅RS, AB≅RS, AB≅RS

And, ∠A ≅ ∠R, ∠B ≅∠S, ∠C≅∠P, ∠D≅∠Q

( +4)+59=70
What is the unknown number

Answers

Heres my guess.....

(x + 4 ) + 59 = 70

x+4+59=70

(x)+(4+59)=70

x+63=70

x+63−63=70−63

x=7

The science fair judges will be science teachers and volunteers. Each judge will only have time to view 5 science fair projects. There are 133 science teachers. What is the fewest number of volunteers needed to have enough judges for all of the projects?

Answers

Answer: The fewest number of volunteers needed to have enough judges for all of the projects is 2.

Step-by-step explanation:

Number of science teachers = 133

Number of science fair projects viewed by each judge = 5

Let the number of judge be n

Since number of volunteers must be multiple of 5 .

According to question,

$5n=135+\text{number of volunteers}\n\n\text{ where, n is a natural number and number of volunteer must be integer}$

So, Possibility for number of volunteers must be 2 to make it divisible by 5.

$5n=133+2\n\n5n=135\n\nn=(135)/(5)\n\nn=27$

Hence, the fewest number of volunteers needed to have enough judges for all of the projects is 2.

the answer is twenty seven

20. The figures are similar. Find x.

Answers

Answer:

Step-by-step explanation:

You can see that both triangles are the same except for one thing: one is smaller. Since 7 is half of 14 and both triangles are similar, x stands for 10. That is because 10 is half of 20! :D

Answer:

X = 10

Step-by-step explanation:

The second figure is half of the first figure

14 divided by 2 = 7 and 20 divided by 2 = 10

So x = 10 in.
