Answer:
6 in long ; 4 in wide
Step-by-step explanation:
With a scale of 1:20
Scaled drawing is 3 in long ; 2 in wide
Actual dimension :
Length = 20 * 3 = 60 in
Width = 20 * 2 = 40 in
Hence, to make a scaled drawing using 1 :10
Dimension :
Length = (1/10) * 60 = 6 inches
Width = (1/10) * 40 = 4 inches
Use the right triangle shown to answer the question.

The cost of a mobile phone processor is directly proportional to its speed.
A 2GHz mobile costs £500.
Let x be the speed of a processor in GHz
Let y be the cost in pounds.
Find a formula linking the variables.
Answer: See explanation
Step-by-step explanation:
We are going to use the formula used in calculating direct proportion which is equal to:
y = kx
where,
x = speed of a processor in GHz
y = the cost in pounds
Therefore, y = kx
500 = 2k
Therefore, y = 2k
12x 5 =(4x 2 )(C)12, x, start superscript, 5, end superscript, equals, left parenthesis, 4, x, squared, right parenthesis, left parenthesis, C, right parenthesis C=
Answer:
3x³
Step-by-step explanation:
Given the expression
12x^5 =(4x^2 )(C)
We are to find the value of C
Rewriting the equation will give;
(4×3)x²•x³ = 4x²C
4x²•3x³ = 4x²C
Divide both sides by 4x²
4x²•3x³/4x² = 4x²C/4x²
3x³= C
Hence the function C is 3x³

Answer:
[tex]Area = 34.2cm^2[/tex]
Step-by-step explanation:
Let the three sides be a, b and c respectively.
Such that:
[tex]a = 8[/tex]
[tex]b = 9[/tex]
[tex]c= 10[/tex]
Required
Determine the area
This is calculated as:
[tex]Area = \sqrt{s(s-a)(s-b)(s-c)[/tex]
Where
[tex]s = \frac{1}{2}(a + b + c)[/tex]
Substitute values for a, b and c
[tex]s = \frac{1}{2}(8 + 9 + 10)[/tex]
[tex]s = \frac{1}{2}(27)[/tex]
[tex]s = 13.5[/tex]
Substitute values for a, b, c and s in
[tex]Area = \sqrt{s(s-a)(s-b)(s-c)[/tex]
[tex]Area = \sqrt{13.5 * (13.5 - 8)* (13.5 - 9)* (13.5 - 10)[/tex]
[tex]Area = \sqrt{13.5 * 5.5* 4.5* 3.5[/tex]
[tex]Area = \sqrt{1169.4375[/tex]
[tex]Area = 34.2[/tex] -- Approximated
The seventh grade class is raising money to have a class trip at the end of the year. They began the year with $1500. They now have $1650 in the account. What is the percent of increase for the money the class has raised ?
Answer:
The percent of the increase for the money the class raised is 10 %
Step-by-step explanation:
Because if you divide 1500 by 10 you get 150 that means 150 is 10 % of 1500 and if you add 150 to 1500 you get 1650 so the increase of money the class raised is 10 %

A leaking faucet drips into a bucket. The faucet drips at a constant rate. The level of water in the bucket rises
3 inches in 6 hours. What was the rate per hour of the water level change?
Answer:
The per hour rate is 0.5 inches per hour
Step-by-step explanation:
Here, we want to calculate the rate at which the level of the water increased
Mathematically, we can get this by dividing the amount of increment by the time it took
That would be 3 inches divided by 6 hours
= 3/6 = 0.5 inches per hour

An angle measures 48.4° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
65.8° and 114.2°
Step-by-step explanation:
Suplementary angles sum 180°
then:
a + b = 180° eq 1
a = b - 48.4 eq 2
replacing the value of eq 2 in eq 1:
(b-48.4) + b = 180°
2b - 48.4 = 180°
2b = 180 + 48.4
2b = 228.4
b = 114.2°
from the eq. 1
a = b - 48.4
a = 114.2 - 48.4
a = 65.8°
Check:
114.2° + 65.8° = 180°

Two times colleen’s age plus three times Ashley’s age equals 108. Colleen’s age is three times Ashley’s age. How old is Colleen
Answer: 36
Step-by-step explanation: 2x36=72. 36/3=12. 3x12=36. 36+72=108.
Answer: 81 yrs
Step-by-step explanation: a stands for Ashley, c stands for Colleen
2c + 3a = 108
c = 3a
3a + a = 108
4a = 108
a = 27
c = 3a
c = 3 (27)
c = 81
5. How much power is dissipated when 0.2 ampere of current flows through a 100-ohm resistor ?
Answer:
4 W
Step-by-step explanation:
Electrical power, P = I²R where I = current and R = resistance.
Given that I = 0.2 A and R = 100 Ω,
P = I²R
P = (0.2 A)² × 100 Ω
P = 0.04 A² × 100 Ω
P = 4 W

Foster’s answer to the question he wrote for Ranger was 7x+(-3), while Ranger’s answer was 7x-3.They both checked their work by letting x=5, and they both claim to be correct.Are they both correct?Explain.
Answer: They are both correct :)
Step-by-step explanation:
They are both correct because 7x + (-3) is the same thing as 7x - 3 if you simplify it.
When you simplify it, you change the expression to:
7x + 1 (-3)
So now you have to distribute the 1 which gives you:
7x - 3
..since positive x negative is negative.

Answer:
y= -4/3x+8
Step-by-step explanation:
y=mx+b is the equation for a line
m=slope
b=y-intercept
First, find the slope
The formula for the slope is: y2-y1/x2-x1
8-0/0-6=
8/-6=4/-3
Plug the slope into the equation
y= -4/3x+b
Now find the y-intercept.
To do this, plug in the x and y of a coordinate and solve for b
I will use (0,8)
8= -4/3(0)+b
8=b
Plug the y-intercept into the equation
y= -4/3x+8
y= -4/3x+8 is your equation
