Answer:
She watched for 6/8 minutes.
Simplified version would be 3/4 minutes.
Hope this helped! :)
Answer:
[tex]\frac{3}{4}[/tex] minutes
Step-by-step explanation:
To find how long she watched, add 1/8 to 5/8
Since they have the same denominators, we can add the numerators together and keep the same denominator.
[tex]\frac{1}{8}[/tex] + [tex]\frac{5}{8}[/tex]
= [tex]\frac{6}{8}[/tex]
This can be reduced to [tex]\frac{3}{4}[/tex], since both numbers are divisible by 2.
So, she watched videos for [tex]\frac{3}{4}[/tex] minutes

Refer to the figure at the right. What percent of the
area of rectangle PQRS is shaded?
A) 12.5%
B) 25%
C) 30%
D) 40%
Step-by-step explanation:
B) 30%, if you put the two pieces together it would be 30% of the rectangle that is shaded
The percent of the area of rectangle PQRS is shaded is 25%.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100.
Given:
The shape is a rectangle and it is cut into half using diagonal.
again cut by another diagonal which 1/4 section.
Now again it is one more time cutted but this time make section of 1/8
As, there are two shaded section
=1/8+1/8
=2/8
=1/4
=1/4 *100
=25%
Hence, percent of the area of rectangle PQRS is shaded is 25%.

the perimeter of the given equilateral triangle is 42 cm find s if it's side length is (3s+2) cm
Answer:
14cm
Step-by-step explanation:
Given parameters:
perimeter of the triangle = 42cm
length of side = (3s + 2)cm
Unknown:
Find the length of each side = ?
Solution:
The perimeter of a body is the sum of all its sides.
In this problem, we have been given an equilateral triangle. For such a triangle, all the sides are equal. So the perimeter is the sum of all the three sides;
(3s + 2) + (3s + 2) + (3s + 2) = 42
9s + 6 = 42
9s = 42 - 6
9s = 36
s = 4;
The length of its sides = 3s + 2
= 3(4) + 2
= 12 + 2
= 14cm
A bathtub is draining at a constant rate. After 3 minutes, it holds 36 gallons of water. Seven minutes later, it holds 15 gallons of water. Write an equation the represents the number y of gallons in the tub after x minutes
Answer:
y = 45 - 3x
Step-by-step explanation:
Given that:
Bathtub drains at a constant rate :
Amount of water in tub after 3 minutes = 36 gallons
Amount of water in tub after 7 minutes later (3 + 7) ;(after 10 minutes) = 15 gallons
Using the slope - intercept relation:
y = mx + c
y = gallons in tub after x minutes
m = slope (rate at which water drains per minute)
C = intercept
Hence,
Amount of water in tub after 3 minutes = 36 gallons ; x = 3,; y = 36
Since water is draining gradient m is negative
36 = c - 3m - - - (1)
Amount of water in tub after 7 minutes later (3 + 7) ;(after 10 minutes) = 15 gallons
15 = c - 10m - - - (2)
Subtract (2) from (1)
21 = - 3m + 10m
21 = 7m
m = 3
From (1)
36 = c - 3(3)
36 = c - 9
36+ 9 = c
45 = c
Hence, the equation becomes ;
y = 45 - 3x

A bus travels 0.8 mile east every 45 seconds. A second bus travels 0.55 mile west every 30 seconds. The buses start at the same location. Use two methods to determine how far apart the buses are after 15 minutes.
Answer:
32.5 miles
Step-by-step explanation:
Given that:
Eastbound bus :
0.8 miles every 45 seconds
Speed per second :
0.8 / 45 = 0.0177777 miles per second
Distance after 15 minutes
(15 * 60) * 0.0177777 = 16 miles
Westbound bus:
0.55 miles every 30 seconds
Speed per second :
0.55 / 30 = 0.0183333 miles per second
Distance after 15 minutes :
(15 * 60) * 0.0183333 = 16.5 miles
Distance apart :
16 miles + 16.5 miles = 32.5 miles
METHOD 2:
Distance covered after 15 minutes :
15 minutes = 15 * 60 = 900 seconds
Distance apart after 900 seconds :
[0.8 * (900/45)] + [0.55 * (900/30)]
16 + 16.5
= 32.5 miles

one batch of cookies requires 2 and 2/3 cups of sugar how much sugar does Angela need if she wants to make one and a half batches
Answer:
4 cups of sugar
Step-by-step explanation:
To solve this, you need to multiply 2 2/3 by 1 1/2. To do this, you need to change both into improper fractions:
2 2/3 --> 8/3
1 1/2 --> 3/2
Now, you need to multiply them together:
8/3 x 3/2
= 24/6
= 8/2
= 4 cups of sugar

Step-by-step explanation:
Janice went to 5 different stores in the mall. She spent an average of $30 at each store. After visiting just the first 4 stores she had spent $100. How much must she have spent
A.)525
B.)$30
С.)$50
D.)$70
We want to find how much Janice spends on her last purchase.
The correct option here is C, she must have spent $50 on the last store.
Let's see how to get the correct answer:
We know that the average is $30 per store, and we know that she goes to 5 stores, then the total amount spent in the 5 stores is:
5*$30 = $150
Notice that average is just given by the total amount of money she spent divided the number of stores she visited, this does not mean that she spent $30 in each of these stores.
Now, we also know that in the first 4 stores she spents a total of $100.
We want to know how much does she spend on the last store, this will be given by the difference between the total amount and $100, this is:
$150 - $100 = $50
So she must have spent $50 on the last store, meaning that the correct option is C.

Answer:
10 years
Step-by-step explanation:
You start by writing an equation:
(2/3) * (15) = x
x being how many years it has been asleep.
Then multiply the two numbers together:
x = 10
Answer:
10 years
Step-by-step explanation:
Divide the cats life by the denominator to find how much it sleeps for 1/3 of its life.
15 3 = 5 years
Multiply 5 by the numerator to find how much it sleeps for 2/3 of its life.
5 * 2 = 10 years

a1= 5, b1= 5, c1 = -10
a2= 2, b2= 2, c2 = -4
Now, a1/ a2 = 5/2
b1/ b2= 5/2
c1/ c2= -10/-4 = 5/2
Hence, a1/a2= b1/b2= c1/c2
So, the pair of equation has no solution.

A tree in the Amazon rain forest grows an average of 2.3 cm per week. Write a sequence that represents the weekly height of the tree if it is 7 meters tall today. Write a recursive formula for the sequence and find the height of the tree after 6 weeks.
Answer:
Recursive formula
= an = a1 +(n - 1)d
Where
a1 = First term
n = nth term
d = common difference
The height of the tree after 6 weeks = 711.5 centimeters or 7.115 meters
Step-by-step explanation:
Recursive formula
= an = a1 +(n - 1)d
Where
a1 = First term
n = nth term
d = common difference
We are told that the tree is 7 meters tall today = a1
We convert to centimeters
1m = 100cm
7m =
Cross Multiply
= 7 × 100cm
= 700cm
And it grows at an average of 2.3cm per week = 2.3
Hence, an = a1 +(n - 1)d
We are to find the height of the tree after 6 weeks
a6 = 700 + (6 - 1) 2.3
a6 = 700 + (5)2.3
a6 = 700 + 11.5
a6 = 711.5cm.
We can convert to meters if we like
= 100 cm = 1 m
711.5 cm =
711.5cm/100
= 7.115m
The height of the tree after 6 weeks is 711.5 cm or 7.11 meters
