i need all of these to be reduced to lowest term, if someone could do a step by step process that'd be great. thank you :)
Answers
Answer:
1.) 3/4
2.) 44/5 or 8 4/5
3.) 17/6 or 2 5/6
Step-by-step explanation:
1.) 5/16 ÷ 5/12
To divide a fraction by another fraction, reciprocate (put the numerator to denominator and vice versa) the divisor then change the sign to multiplication:
5/16 × 12/5
5 × 12 / 16 × 5
Cancel out 5 since both numerator and denominator has it:
12 / 16
Divide both by 4:
12 ÷ 4 / 16 ÷ 4
3/4
2.) 3 1/5 • 2 3/4
You have to convert the fractions first to improper fractions by multiplying the denominator to the whole number then adding the numerator to the product:
3 1/5 = 3×5 + 1 = 16/5
2 3/4 = 2 × 4 + 3 = 11/4
Now you can multiply the numerator to numerator then denominator to denominator:
Since 16 is a factor of 4, you can cancel it out, which leaves 4:
16 / 5 × 11/4
4 × 11 / 5 × 1
44/ 5
3.) 6 3/8 ÷ 2 1/4
Convert to improper fraction:
6 3/8 = 6× 8 + 3 = 51/8
2 1/4 = 4 × 2 + 1 = 9/4
(51 × 4)/ (9×8)
51 × 1/ 9× 2
51 / 18
Divide by 3:

Two friends race. The first friend gets a head start and runs at a steady rate of 0.20 miles per minute. The second friend waits 1 minute and then runs at a steady rate of 0.25 miles per minute. How long will it take for the second runner to catch up with the first?
Answers
Step-by-step explanation:
In this problem we are expected to solve for the time taken for the second person to meet with the first.
given that
first person's speed=0.2mph
let time taken be= x
we know that
velocity= distance/time
0.2=distance/x
distance=0.2x----1
second person's speed= 0.25mpm
time taken=x-1
we know that
velocity= distance/time
0.25=distance/x-1
distance=0.25(x-1)
distance=0.25x-0.25-----2
equating equation 1 and 2 we have
0.2x=0.25x-0.25
0.2x-0.25=-0.25
-0.05x=-0.25
divide both sides by -0.05 we have
x=-0.25/-0.05
x=5
we know that the second person's time is described by
=x-1
=5-1=4min
The second person will catch up after 4 minutes

Use the properties of an Isosceles Triangle to solve for x and y.
AJKL is an isosceles triangle. Find the values of x and y
Answers
Answer:
x = 3y = 11Step-by-step explanation:
isosceles triangle
solve for x:
JK = KL
8x = 13x - 15
15 = 13x - 8x
15 = 5x
x = 3
solve for y:
180 = 76 + 2(5y - 3)
180 - 76 = 10y - 6
10y = 110
y = 11

All perfect squares are divisible by 2.
A.) true
B.) False, counterexample of 16
C.) False, counterexample of 15
D.) False, counterexample of 25
Answers
Answer:
the correct answer is C
Step-by-step explanation:
because the square root of 15 is 3.8 and 3.8 isnt divisible by 2
The reason for that is because A is not true, B is not a counterexample, C is not a square, so D is the answer.

Step-by-Step explanation:
Sin16°= XZ/YZ
YZ=XZ/sin16°
YZ=7/0.276
YZ=25.3623188405797
YZ = 25.40 correct to 1dp
Answer:
XZ ≈ 24.39
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan16° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{XZ}{YZ}[/tex] = [tex]\frac{7}{YZ}[/tex] ( multiply both sides by YZ )
YZ × tan16° = 7
YZ × 0.287 = 7 ( divide both sides by 0.287 )
YZ = [tex]\frac{7}{0.287}[/tex] ≈ 24.39 ( to 2 dec. places )

What are trigonometric ratios in terms of a right-angle triangle?We know a right-angled triangle has three sides they are -: Hypotenuse,
Opposite and Adjacent.
We can remember SOH CAH TOA which is,
sin = opposite/hypotenuse, cos = adjecen/hypotenuse and
tan = opposite/adjacent.
Given, A mountain has a 20-degree slope and is 1 mile tall and we have to hike the mountain so we want to know the distance.
Here hypotenuse is the distance we have to hike and according to the reference, the angle opposite has a distance of 1 mile.
We know sin = opposite/hypotenuse.
sin20° = 1/hypotenuse.
0.342 = 1/hypotenuse.
hypotenuse = 1/0.342.
hypotenuse = 2.92 miles.

Answer:
5.319149 oz per dollar
Step-by-step explanation:
This is a fraction equal to
10 oz ÷ 1.88 dollars
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 1.88
10 oz ÷ 1.88
1.88 dollars ÷ 1.88
=
5.319149 oz
1 dollar
=
5.319149 oz
dollar
= 5.319149 oz per dollar
