The variables x and y are related proportionally. When x = 4, y = 14. Find y when x = 40.
When x = 40, y =
Answer:
See Below
Step-by-step explanation:
Take the the given information and compare to the question being asked
[tex]\frac{y}{x}[/tex]. So insert the x & y's of both equations (ima do y over x to make it easier)
[tex]\frac{14}{4} =\frac{y}{40}[/tex]
divide 14/4
3.5 = [tex]\frac{y}{40}[/tex]
then multiply both sides by 40 to isolate y
140 = y
Check by reinserting 140 and divide it by 40
Answer:
y= 140
Step-by-step explanation:
if they are directly proportional, that means when one increases/decreases the other does as well.
x increased by multiplying itself by ten. Like before, since they are both directly proportional that means that y is multiplied by 10.
14*10= 140, y=140

Answer:
So for the triangle, we have x = 25 and the angles 45-75-60.
So for the quadrilateral, we have x = 75 and the angles 70-110-75-105.
Step-by-step explanation:
For each of these problems, we can simply add the expressions of the angles given matched to the sum of the angles for the shape given below. Once we do this, we can solve for x, and then state the given measures of each angle of the shapes.
For the triangle:
60 + ( x + 20 ) + 3x = 180
60 + x + 20 + 3x = 180
60 + 20 + x + 3x = 180
80 + x ( 1 + 3 ) = 180
80 + x ( 4 ) = 180
80 + 4x = 180
4x = 100
x = 25
We have the given angles:
x + 20 ==> 25 + 20 ==> 45
3x ==> 3 (25) ==> 75
60
So for the triangle, we have the angles 45-75-60.
For the quadrilateral:
( x - 5 ) + ( x + 35 ) + x + 1.4x = 360
x - 5 + x + 35 + x + 1.4x = 360
35 - 5 + x + x + x + 1.4x = 360
30 + x ( 1 + 1 + 1 + 1.4 ) = 360
30 + x ( 4.4 ) = 360
30 + 4.4x = 360
4.4x = 330
x = 75
So, we have the given angles:
x - 5 ==> 75 - 5 ==> 70
x + 35 ==> 75 + 35 ==> 110
x ==> 75
1.4x ==> 1.4(75) ==> 105
So for the quadrilateral, we have the angles 70-110-75-105.

Larry's car depreciated 30% during the first year he owned it. If he paid $24,750 for the car, what was his car worth the second year?
Answer:
$17,325
Step-by-step explanation:
24,750 × 30/100
= 2,475 × 3
= $7,425
the car is depreciated by $7,425
now the price in the 2nd year is,
24,750 - 7,425
= $17,325
Two numbers have square roots about 40 apart. What could they be?
The two numbers such that their square roots about 40 apart will be 2401 and 81.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
Let's consider the number 8² = 64
Now, 64 - x = 40
x = 64 -40 = 24 and it is not a square of any number.
Take, 7² = 49
49 - x = 40
x = 9 it is a square of 3.
Thus, 7² - 3² = 40
So, 49² = 2401 and 9² = 81
Hence "The two numbers such that their square roots about 40 apart will be 2401 and 81".

You want to build this bookshelf. Given that a∥ b and m∠3=x and m∠2=x+30. Find the measure of ∠4, ∠5, and ∠6
m<4= ___ Degrees
m<5= ___ Degrees
m<6= ___ Degrees
Answer:
[tex]\huge\boxed{m \angle 4 = 105 \textdegree}[/tex]
[tex]\huge\boxed{m \angle 5 = 75 \textdegree}[/tex]
[tex]\huge\boxed{m \angle 6 = 105 \textdegree}[/tex]
Step-by-step explanation:
We can use basic angle relationships to find the measures of m∠4, m∠5, and m∠6.
We know that angles m∠3 and m∠2 are supplementary. This means their angle lengths add up to 180°. Since we know the expression for both, we can add them and solve for x.
[tex](x) + (x+30)=180[/tex] [tex]2x+30=180[/tex] [tex]2x=150[/tex] [tex]x = 75[/tex]So x = 75°, aka m∠3 is 75°. This means m∠2 is going to be [tex]75+30=105[/tex]°.
m∠4 is an opposite angle to m∠2. This means their angle lengths are the same. Therefore, m∠4 is 105°.
We also know that m∠3 and m∠5 are alternate interior angles, meaning their angle lengths are the same. Since m∠3 is 75°, m∠5 is also 75°.
We also know that m∠6 is a corresponding angle to m∠2. This means their angle lengths are the same. Since m∠2 is 105°, m∠6 is also 105°.
Hope this helped!

A volunteer is buying 10 blankets for the animal shelter. Shipping the blankets costs $1.50 and the volunteer has $75 to spend. What is the maximum amount the volunteer can spend for each blanket? Write an inequality that would represent the situation and solve the inequality. Show your work to justify your answer.
Answer:
they have $60 dollars because 10 times 1.50 is $15 so they have $60 to spend on blankets
Step-by-step explanation:
The maximum amount spent on each blanket is required.
The maximum amount that can be spent on each blanket is $7.35
Number of blankets is 10.
Let cost of one blanket be [tex]x[/tex]
The cost of shipping 10 blankets is $1.5
Total amount to spent is $150 or less.
The inequality will be
[tex]10x+1.5\leq 150\\\Rightarrow x\leq \dfrac{150-1.5}{10}\\\Rightarrow x\leq 7.35[/tex]
The maximum amount that can be spent on each blanket is $7.35.

Which pair of angles are an example of supplementary angles?
A. Angle 1 and Angle 7
B. Angle 3 and Angle 6
C. Angle 2 and Angle 7
D. Angle 1 and Angle 4
Answer: A. Angle 1 and Angle 7
Step-by-step explanation:
A: Angle 1 and 7 are same side exterior angles so they are not equal but add up to 180 degrees and supplementary angles add up to 180 degrees.
B. Angle 3 and Angle 6 are alternate interior angles so Angle 3 and Angle 6 are equal.
C. Angle 2 and Angle 7 are alternate exterior angles so Angle 2 and Angle 7 are equal.
D. Angle 1 and Angle 4 are vertical angles so Angle 1 and Angle 4 are equal.
The pair of angles that demonstrate a pair of supplementary angles in the given figure would be:
A). Angle 1 and Angle 7
Supplementary angles are characterized as the two angles(one angle added to another referenced angle) that together sum up to be 180 degrees.
For example, the pair of 70° and 110° angles would be characterized as supplementary angles as they have a total of 180°.
In the given figure, ∠1 and ∠7 would be the pair of supplementary angles because they are the exterior angles located on the very same side of the transversal.The second option is incorrect as ∠3 and ∠6 exemplify alternate interior angles and carry equal measurement. While the third option is incorrect as ∠2 and ∠7 illustrate alternate exterior angles and they are equal too. The last option is wrong because ∠1 and ∠4 exemplify vertically opposite angles and they are equal.Thus, option A is the correct answer.Learn more about 'angles' here:
