What kind of proportion tells that when one quantity is increasing or decreasing, the other quantity also increasing or decreasing? A. Direct Proportion B. Indirect Proportion C. Partitive Proportion
Answer:
a
Step-by-step explanation:
Direct proportion is when two numbers move in the same direction. If one of the numbers increase, the other number increases and if the one of the numbers decrease, the other number decreases. The magnitude of the movement of the numbers is bounded by a constant
The expression for direct proportion is
y ∝ kx
where k is the constant
let illustrate with an example :
If x = 10
k = 4
y = 10 x4 = 40

The Answer is YES
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
Use Pythagorean theorem.
The longest side will be the hypotenuse
Hypotenuse² = 17² = 289
base² + altitude² = 15² + 8²
= 225 + 64
= 289 =Hypotenuse²
So, 8 m , 15 m , 17 m forms a right angled triangle

Hope it helpsWhich is the equation of the line that passes through the points (4,3) and (6,2)?
A. Y= x - 1
B. Y= 0.5x - 1
C. Y= -0.5x + 5
D. Y= -0.5x + 1
Answer:
[tex] \large \boxed{y = - 0.5x + 5}[/tex]
Step-by-step explanation:
Goal
Find the equation of the line.Given
Coordinate points which are (4,3) and (6,2).Step 1
Find the slope by using slope formula or rise over run.[tex] \large{m = \frac{y_2-y_1}{x_2-x_1} }[/tex]
Substitute the coordinate points in
[tex]m = \frac{3 - 2}{4 - 6} \\ m = \frac{1}{ - 2} \\ m = - \frac{1}{2} \longrightarrow - 0.5 \\ m = - 0.5[/tex]
Step 2
Rewrite the equation in slope-intercept form by substituting m = -0.5[tex] \large{y = mx + b}[/tex]
Substitute m = -0.5
[tex]y = - 0.5x + b[/tex]
Step 3
Find the value of b by substituting any given coordinate points in the equation.Substituting both coordinate points still give the same answer.
Step 3.1
Substitute (4,3) in the equation.[tex]y = - 0.5x + b \\ 3 = - 0.5(4) + b \\ 3 = - 2.0 + b \\ 3 = - 2 + b \\ 3 + 2 = b \\ 5 = b[/tex]
Step 3.2
Substitute (6,2) in the equation.[tex]y = - 0.5 x+ b \\ 2 = - 0.5(6) + b \\ 2 = - 3.0 + b \\ 2 = - 3 + b \\ 2 + 3 = b \\ 5 = b[/tex]
Step 4
Rewrite the equation again by substituting the value of b.[tex]y = - 0.5x + b[/tex]
Substitute b = 5 in the equation.
[tex]y = - 0.5x + 5[/tex]
Hence, the equation is y = -0.5x + 5

Wind farms are a source of renewable energy found around the world. The power P (in kilowatts) generated by a wind turbine varies directly as the cube of the wind speed v (in meters per second). If a turbine generates 700 kW in a 12 m/s wind, how much power does it generate in a 6 m/s wind?
(The formula for P as a power function of v is P = a ⋅ v3.
A. 88 kW
B. 175 kW
C. 125 kW
D. 1050 kW
Answer:
New power = 88 Kw (Approx.)
Step-by-step explanation:
Given:
P = a(v³)
Old power p = 700 Kw
Old wind speed v = 12 m/s
Find:
New power when v = 6m/s
Computation:
P = a(v³)
700 = a(12³)
a = 0.4050 m²
New power = a(v³)
New power = (0.4050)(6³)
New power = 87.48
New power = 88 Kw (Approx.)
Rachel has been given $1000 to put into a savings account. She earns 2% simple interest
every month. Rachel hopes to buy a car in two years. Help Rachel determine whether she
will have enough money if the car will cost $1500.
Answer:
She will not have enough. She will only have $1480.
Step-by-step explanation:
The formula for simple interest is A=P(1+rt)
A=final amount
P=initial amount
r=interest rate per month
t=time in months
A=1000(1+(0.02)(24))=1480
Rachel will not have enough money after two years (24 months.)

What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
A spinner with six section numbered from 1 to 6.
total number of times spins = 150
So, the number of times the number comes less than 5 is
= 150 x 1/5
= 150/5
= 30

How would you express the area of the rectangle using the Distributive Property?
Answer:
C
Step-by-step explanation:
Step 1: Find your legth and width
Length = x + 5
Width = 3
Step 2: Use area formula to find area
l x w = A
(x + 5) x 3 = A
A = 3(x+5)
Step 3: Therefore Statement
Thereforethe answer to the question is C. 3(x+5)
Answer:
C. 3(x + 5)
Step-by-step explanation:
area of rectangle = length * width = width * length
A = area of largest rectangle
a1 = area of left rectangle
a2 = area of right triangle
The largest rectangle is made up of the the two smaller rectangles.
A = a1 + a2
Left rectangle: a1 = WL = 3x
Right rectangle: a2 = WL = 3 * 5
Total area of the two small rectangles:
A = a1 + a2 = 3x + 3 * 5
Apply the distributive property in reverse to 3x + 3 * 5 by factoring out a 3:
A = 3x + 3 * 5 = 3(x + 5)
The area of the largest rectangle is 3(x + 5)
We can also find an expression for the area of the largest rectangle directly by looking at its length and width.
The length of the largest rectangle is x + 5.
The width of the largest rectangle is 3.
A = WL
Substitute 3 for W, the width.
Substitute x + 5 for L, the length.
A = 3(x + 5)
Answer: C. 3(x + 5)

1.) The length of a rectangle is 4 cm longer than the width. The
perimeter is 80 cm. Find the length and width. Write a system and
use substitution to solve.
Step-by-step explanation:
if a rectangle has 4 sides and there are two lengths and two widths
then we could split 80 by 2 and minus 4 from the length and then split that into two.
then your answer would be and 36 and 44
and the total answer would be half of each so the L=22 and L=22
and the W=18 and W= 18

What is the equation.
For a field trip 4 students rode in cars and the rest filled nine busses. How many students were in each bus if there were 472 students on the trip.
4x - 9 = 472
4x - 9 = 472
4x + 9 = 472
4x + 9 = 472
9x - 4 = 472
9x - 4 = 472
9x + 4 = 472
9x + 4 = 472
Step by Step Explanation
We know there are 9 buses, but we don't know how many students are on the buses, so that makes the first part of the equation 9x.
We also know there are 4 students in cars, so we now have an equation of 9x + 4.
We also know there is a total of 472 students altogether, so now our final equation is 9x + 4 = 472

The machine gun and the tank were new technologies that influenced WW1 the most. The machine gun lengthened the war and forced it to become a trench war. The bullets in a machine gun could shoot 500 bullets per minute therefor making it much more difficult for the rivalry county to fight back.
