Answer:

61 degrees

Step-by-step explanation:

a triangle measures 180 degrees

so your going to add 87 and 32 which gives us 119

since a triangle measures 180 degrees u you are going to subtract 119 from 180 which gives us 61 degrees

Max drove 460 miles in 8 hours at a constant speed. How long would it take him to drive 661.25 miles at that speed?
lord [1]
460/8 = 57.5 They were going 57.5 mph 

661.25/57.5mph = 11.5

It will take them 11 and a half hours go get wherever they're going.

The sum of two numbers is 24. The second number minus the first number equals 2.
Sonbull [250]

Answer:

(11, 13)

Step-by-step explanation:

First Equation: x+y=24

Second Equation: y=x+2

x + (x + 2) = 24

2x + 2 - 2 = 24 - 2

2x/2 = 22/2

x = 11

y = (11) + 2

y = 13

Therefore, the solution to the system is (11, 13)

PLEASE HELP ME WITH THIS PROBLEM!!
madam [21]
To solve this question, we should know the Triangle Inequality Theorem.

The triangle inequality theorem says something like: The sum of any two sides of a triangle must be greater than than the length of the third side

Making that into a formula, considering the side lengths are a, b, and c.
a + b > c
a + c > b
b+ c > a

So:
Lets test answer choice A.

The sides will then be: 34, 12, and 21

34 + 12 > 21 -> 46 > 12 True
12 + 21 > 34 -> 33 > 34 False

A is not the correct answer choice.

Lets try answer choice B.

The sides for this would be: 34, 12, and 30

34 + 12 > 30 -> 46 > 30 True
12 + 30 > 34 -> 42 > 34 True
30 + 12 > 34 -> 42 > 34 True

So B is correct.

Lets try C to make sure.

The side lengths would be: 34, 12, and 46

34 + 12 > 46 -> 46 > 46 False

So C is wrong.

Lets just make sure D is also wrong, and then we will know for sure if B is the answer :)

Side lengths of answer choice D: 34, 12, and 50

34 + 12 > 50 -> 46 > 50 False

So B is indeed our answer. :)

Another way to solve it is to:

We are given side lengths of 34 and 12.

That means the other side has to be greater than the different of 34 and 12 and less than the sum of 34 and 12.

Lets say that c is the third side, then:

34 -12 < c < 34 + 12
22 < c < 46

And by looking at this range, and the answer choices we know that B) 30 is the answer because the others are at the border and since it isn't greater than or equal to/less than or equal to, we can not include it.Or either the answer choices are out of the range.

So the final answer is \boxed{\bf{B)~30~cm}}

Margo has 15 pounds of clay, Tim has 10 pounds of clay, Tray has 13 pounds of clay, Lila has 14 pounds of clay, and Jerry has 13
poizon [28]

Answer:

13 clay for each person

Step-by-step explanation:

Add all the clay to find the total.

15+10+13+14+13= 65 clay in total

There are 5 people in total.

Divide 65 by 5 to find the distribution for each person.

65÷5= 13

Each person get 13 clay after redistribution.
