See the detailed answers below
Step-by-step explanation:
Given data
Ratio= 1:4:7
combined ratio= 1+4+7= 12
Total amount= $636,000
Apply the part to all method
The first person will take
1/12= x/ 636,000
cross multiply
12x= 636,000*1
x= 636,000/12
x= 53000
The second person will take
4/12= x/ 636,000
cross multiply
12x= 636,000*4
x= 2544000/12
x= 212000
The third person will take
7/12= x/ 636,000
cross multiply
12x= 636,000*7
x= 4452000/12

minutes, it rises at a rate of 40 feet per minute. What integer represents the
position of the submarine after the six minutes?
Answer:

For what value of x is line / parallel to line m in this figure?
Answer:
132
Step-by-step explanation:
The angle with a measure of 48 degrees and the angle labeled "x" are supplementary angles. Supplementary angles add up to equal 180
This means that we can find the value of the missing angle by subtracting the measure of the known angle from 180
So x = 180 - 48
180 - 48 = 132
Hence, x = 132
Kevin needs to buy some cardboard to build a box 11 inches long, 7 inches wide, and 10 inches high. How much cardboard is needed to build the box?

Find the indicated side of the
triangle.
17
45°
a = [?][ ]
The indicated side of the triangle is 17√2 unit.
What is Pythagoras theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
The triangle is a right-angled triangle.
The length of the perpendicular = 17 unit.
Two angles of the triangle are 45° and 45°.
That means, base = 17 unit.
And the triangle is an isosceles triangle.
By the Pythagoras' theorem,
a = √(289 + 289)
a = √578
a = 17√2 unit.
Therefore, the value of a is 17√2 unit.

Step-by-step explanation:
PLEASE ANSWER CORRECTLY <3 I WILL GIVE BRAINLIEST THANKS IN ADVANCE!
Answer:
1: 130
2: 70
Step-by-step explanation:
Supplementary angles add up to equal 180
So to find the measure of the missing angles, we subtract the measure of the known angles from 180
For #1
∠B = 180 - 50
180 - 50 = 130
Hence ∠B = 130
For#2
∠D = 180 - 110
180 - 110 = 70
Hence, ∠D = 70
