Hey there!
When you see the word “of” in mathematical statement, it usually means “multiply” (aka Multiplication)
“3/5 of 5/9”
3/5 • 5/9
MULTIPLY the NUMERATORS (TOP NUMBERS) from each other & also MULTIPLY the DENOMINATORS (BOTTOM NUMBERS) from each other!
3(5) / 5(9)
3(5) = 15 ⬅️ NUMERATOR
5(9) = 45 ⬅️ DENOMINATOR
15/45
The GCF (Greatest Common Factor) for both of your numbers is: 15.. so DIVIDE both the NUMERATOR and DENOMINATOR from 15
15 ÷ 15 / 45 ÷ 15
15 ÷ 15 = 1 ⬅️ NUMERATOR
45 ÷ 15 = 3 ⬅️ DENOMINATOR
Answer: 1/3 ☑️
Good luck on your assignment and enjoy your day!

Find the unit rate.
180 miles in 3 hours
Answer:
60 miles per hour
Step-by-step explanation:
First, put the equation in a fraction.
You would put 180 up top because people always say miles per hour not the other way around.
You can see the dividing line as your "per" and your "hour" would be the bottom number.
To find the unit rate, you will divide the numerator (180) and the denominator (3).
Your final answer should be 60 miles per hour.
[tex]\frac{180}{3} = \frac{60}{1}= 60[/tex]
True or False: The following table is proportional
Answer:
True
Step-by-Step
When the x was 2, the y was 11.
When the x was 4, the y was 19.
So for every two on the x side, the y side adds 8.
So yes, there's a pattern AKA, this a proportional table.

Answer:
5 meters in milli is 5,000. 5,000 is more than 4996
Step-by-step explanation:
Answer:
5 meters
Step-by-step explanation:
one meter equals 1000 millimeters so obv 5 meters is bigger
one number is three times of the other and their arithmetic mean is 10 find them
Step-by-step explanation:
data
let the unknown numbers = x and y respectively
y is 3 × greater than x so, y = 3x
x+y/ 2 = 10
solution:
x + 3x= 10
4x=10
divide both sides by 4
x=4/10 or 2 1/2Which measurements could NOT represent the side lengths of a right triangle?

O 20 cm, 21 cm, 29 cm
O 36 cm, 77 cm, 85 cm
O 7 cm, 28 cm, 32 cm
Step-by-step explanation:
A. 8 cm, 15 cm, 17 cm => This is a right triangle.
B. 20 cm, 21 cm, 29 cm => This is a right triangle.
C. 36 cm, 77 cm, 85 cm => This is a right triangle.
D. 7 cm, 28 cm, 32 cm => This is not a right triangle.
Which of the expressions below has the value found farthest to the left on a
number line?
A. 7-10
B. -7 - 10
C. 10 - (-7)
D. 10 - 7
Answer:
-7 - 10
Step-by-step explanation:
The values found farthest to the left of a numbwr line are negative values, with positive values located to the right and 0 being the midpoint.
Thus positive values increase towards the right of the number line while negative values on the other hand reduces as we move farther to the left of the number line.
Hence , from the options given, - 7 - 10 gives a total of - 17 is the lowest negative value given in the option.

Which expression is equivalent to (4g3h2k4)3
Answer:

[tex]\frac{(4g^{3} h^{2}k^{4} )^{3} }{8g^{3}h^{2} } - (h^{5} k^{3} )^{5}[/tex] [tex]= 8g^{6}h^{4} k^{12} - (h^{25} k^{15} )[/tex]
Step-by-step explanation:
Explanation
Given expression
= [tex]\frac{(4g^{3} h^{2}k^{4} )^{3} }{8g^{3}h^{2} } - (h^{5} k^{3} )^{5}[/tex]
By using
(ab)ⁿ = aⁿbⁿ
[tex]\frac{a^{m} }{a^{n} } = a^{m-n}[/tex]
= [tex]\frac{(4)^{3} g^{9} h^{6}k^{12} ) }{8g^{3}h^{2} } - (h^{5} k^{3} )^{5}[/tex]
After simplification , we get
[tex]= 8g^{9}g^{-3} h^{6} h^{-2} k^{12} - (h^{5} k^{3} )^{5}[/tex]
[tex]= 8g^{9-3}h^{6-2} k^{12} - (h^{5} k^{3} )^{5}[/tex]
[tex]= 8g^{6}h^{4} k^{12} - (h^{25} k^{15} )[/tex]
What is the image of (6,-7) after a reflection over the line y=x
Anyone know how to solve these
Answer:
1: 64π
2: 49π and 153.86
Step-by-step explanation:
For the first one we know that it has a diameter of 16 which means it has a radius of 8 (half the diameter)
To find the area of a circle use the following formula
π*r² where r is the radius
This means that the first answer is π*8^2
which is 64π
For the second one it's the same deal but the radius is 7
so the answer is 49π

Find the x - intercept and
y - intercept of the graph of the
equation 4x + 7y = 6
Step-by-step explanation:
Step-by-step explanation:
x- intercept is the x coordinate when y is 0
4x + 7(0) = 6
4x = 6
x = 1.5
(1.5, 0)
y- intercept is when x is 0
4(0) + 7y = 6
7y = 6
y = 6/7
( 0, 6/7)

Which inequalaty Is shown in this grap
Answer:
C. y ≤ -2x - 2Step-by-step explanation:
Lets analyze the graph:
1. It is decreasing function as line goes down as x-value increases. It means the slope is negative. We have two same negatives: -22. Line is solid, so the inequality sign is either ≤ or ≥3. Shaded region is 'under' the line, it means the sign is ≤Based on above observations and the fact that all have same y-intercept of -2, we can say required inequality is:
y ≤ -2x - 2Correct option is C
find the value of x in the figure
Answer:
25°
Step-by-step explanation:
from the triangle on the left, angles BAD and BDA are equal
angles in a triangle add up to 180°
so 180 - 80 = 100 /2 = 50°
now the straight line ADC angle is 180°
so 180° - 50° = 130 ° for angle BDC
the angle for x is the same as angle DBC
for the triangle on the right angles must add up to 180°
180 - 130 = 2x
50 = 2x
25° =x
Answer:
50
Step-by-step explanation:
let a,b
a=b being base angles.of isoceles triangle
80+a+b=180 sum of angles of triangle
80+a+a=180
2a=100
a=50
80+a+x=180 being sum of angles of triangle
50+a=100
x=50

A rectangular paperboard measuring 35in long and 26in wide has a semicircle cut out of it, as shown below.
Find the area of the paperboard that remains. Use the value 3.14 for π(pi), and do not round your answer. Be sure to include the correct unit in your answer
Answer:
644.67 in^2 remaining
Step-by-step explanation:
So first find the area of this rectangle
rectangle area formula= A=LW
35*26=910
Now we have to find the semi circle value
so we know the diameter is 26 becuase the 2 sides (26 in) are equal and if you fill in the circle the diameter is still 26
A circle formula is
A= π*radius^2
So to find radius divide the diameter by 2
26/2=13
now 13^2=169
Now 169 *3.14 since asked that pi is 3.14
169*3.14=530.66
But Thats the whole circle
The circle that seems to be cut off is half of the original Circle so we half the original circle
530.66/2=265.33
Now we subtract that from the original
910-265.33=644.67
So
644.67 In^2
Thirty years ago Mike McNamara cycled 445.0km in 12 hours – a new British men’s record at that time. In the same time trial Beryl Burton (who died last year) completed 446.2km.
How much faster was Beryl Burton’s average speed than Mike McNamara’s (in metres per hour)?
Answer:
1000m/h
Step-by-step explanation:
You figure out both of the cyclists km/h times but converting their distance in the 12 hours into a rate
Mike McNamara:
[tex]\frac{445}{12}[/tex]
Beryl Burton:
[tex]\frac{446.2}{12}[/tex]
You then divide the denominator (12) by itself so that it becomes 1
Mike McNamara:
[tex]\frac{445}{12}[/tex] = [tex]\frac{445/12}{1}[/tex]
Beryl Burton:
[tex]\frac{446.2}{12}[/tex] = [tex]\frac{446.2/12}{1}[/tex]
You then divide the numerators by what you divided the denominator by (12) to get the km/h
Mike McNamara:
[tex]\frac{445}{12}[/tex] = 37.08km/h (rounded to two decimal places)
Beryl Burton:
[tex]\frac{446.2}{12}[/tex] = 37.18km/h (rounded to two decimal places)
You them have to convert km/h to m/h by multiplying the numerators (37.08 & 37.18) by 1000 to get the distance in metres
Mike McNamara:
37.08 x 1000
= 37080m
=37080m/h
Beryl Burton
31.18 x 1000
= 37180m
= 37080m/h
Therefore Beryl Burton's average speed was faster than Mike McNamara's by 1000m/h
