Answer:
80
Step-by-step explanation:
We can start of with Junior's age. Then if dad is twice as old as Junior, then we add 2 parts and get 3 parts. Then Gramps is twice as old as Dad so we add 4 parts and get 7 parts. Now we divided 140 by 7. We get 20. This is Junior's age. By looking at that, we know Dad is 40, and Gramps is 80.
Gramps is 80 years old.
Hi! I'm happy to help!
We can say that Junior is x years old. This would mean that Dad is 2x years old, and Gramps is 4x years old. All together, their age is 7x. We can write an equation to solve.
7x=140
Divide both sides by 7 to find out x.
x=20
This means that Junior is 20 years old. Dad is double that, so he is 40 years old. And Gramps is double that so he is 80 years old.
To check our answer we can add all of them together.
20+40+80
140
This means that Gramps is 80 years old.
I hope this was helpful, keep learning! :D

Answer:
the first term is -4
the difference is 3.
*notice how each term increases by 3:
-4 + 3 = -1
-1 + 3 = 2
2 + 3 = 5
Step-by-step explanation:
44,587 plus what equals 65,000
Let the missing number be x.
=> x + 44587 = 65000
=> x = 65000 - 44587
= 20413
Ans.= The missing number will be 20413.

find the three consecutive 0dd integers such that two is less than 15 than 5 times the firs
Step-by-step explanation:
Find three consecutive odd integers such that the sum of the last two is 15 less than 5 times the first.
let the consecutive odd integers are :- x , x + 2 and x + 4.
According to question :-
the sum of the last two is 15 less than 5 times the first.
It means that
the sum of ( x + 2 ) and ( x + 4 ) is 15 less than 5 times the x .
( x + 2 ) + ( x + 4 ) = 5x - 15
x + 2 + x + 4 = 5x - 15
2x + 6 = 5x - 15
6 + 15 = 5x + 2x
21 = 7x
or ;
7x = 21
x = 21 / 7
x = 3
So, the consecutive odd numbers are :-
x = 3
x + 2 = 3 + 2 = 5
x + 4 = 3 + 4 = 7
=> 3 , 5 and 7

а/8 = $1.25
Can someone help explain
Answer:
a= $10.00
Step-by-step explanation:
It's very simple. Move /8 to the other side of the equation. It should give you $1.25 x 8. Solve the multiplication and you should get $10.00.
If I didn't make my explanation clear enough, please comment. I sometimes don't even explain myself very well.
Answer:
a = 10
Step-by-step explanation:
a/8 = 1.25
multiply both sides by 8 to isolate a.
(8)(a/8) = 1.25(8)
which gives you
a = 1.25(8)
which simplifies to
a = 10

Which point should be removed for the graph to represent a table of equivalent ratios?
A. (2, 10)
B. (3, 15)
C. (4, 20)
D. (5, 15)
===========================================================
Explanation:
As the graph shows, three of the four points are on the same line. That line being y = 5x. This line has slope 5 and y intercept 0.
The point not fitting this pattern is the point (5,15), so that is the final answer.
For the other three points, note that the jump from x to y coordinate is "times 5". For example, y = 5x = 5*2 = 10 for point A. In contrast, point D has a jump of "times 3" when going from x to y.
--------------
Alternatively, you can divide each y coordinate by its corresponding x coordinate.
For choice A, we have y/x = 10/2 = 5Choice B has y/x = 15/3 = 5Choice C has y/x = 20/4 = 5All results are 5 so far. Choice D doesn't follow the trend and instead has y/x = 15/5 = 3. This is another way to show that choice D is the answer.

45.88 feet
34.88 feet
22.47 feet
19.59 feet
Answer:
34.88
Step-by-step explanation:
I took the test
The distance between the building and the ladder is 34.88 foot, the correct option is B.
What is a Right Triangle?A triangle in which one of the angle measure is equal to 90 degree is called a right triangle.
The ladder forms a right triangle with the building and the ground,
The length of the triangle is 40 foot
The angle made by the ladder is 29.32 degree
By using Trigonometric Ratios
cos 29.32 = Base / Hypotenuse
cos 29.32 = Base / 40
Base is the distance between the building and the ladder.
Base = 34.88 foot

By AA similarity triangle ABC is similar to triangle SUT. Therefore, option A is the correct answer.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
In the given triangle ABC, ∠C=180°-90°-31°
∠C=59°
In the given triangle SUT, ∠U=180°-90°-31°
∠U=59°
Here, ∠B=∠T (Given)
∠C=∠U (Obtained using angle sum property of a triangle)
So, by AA similarity ΔABC is similar to ΔSUT.
Therefore, option A is the correct answer.
