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.

Which system of equations has no solution?
5 x + 5 y = 10 and 2 x + 2 y = 4
3 x minus 6 y = 4 and negative 4 x + 8 y = 7
6 x + 2 y = 6 and 7 x + 3 y = 9
3 x minus 4 y = 16 and 2 x + 3 y = 5
The equation which has no solutions is 5 x + 5 y = 10 and 2 x + 2 y = 4
What is equation?
An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
As,
5 x + 5 y = 10 and 2 x + 2 y = 4
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.

Step-by-step explanation:
since its moving at 11.2 meters per second then you multiply 11.2 times 60. You should get 672 meters per minute. Now you need to multiply 672 by 2 to get the answer 1344
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

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

ABC=40 and Bd is angle bisector of ABC what is ABD= ?
Answer:
20
Step-by-step explanation:
40 ÷ 2 = 20
its 20 since BD is an angle that bisects " divdes " angles in half.
The measure of angle ABD is 20 degrees and this can be determined by using the properties of the angle bisector.
Given :
ABC = 40 and BD is the angle bisector of angle ABC.
The following steps can be used in order to determine the angle ABD:
Step 1 - According to the given data, BD is the angle bisector of angle ABC.
Step 2 - An angle bisector bisects the angle into two equal parts.
Step 3 - So, the measure of angle ABD is calculated as:
[tex]\angle ABD = \dfrac{\angle ABC}{2}\\\\ \angle ABD = \dfrac{40}{2}\\\\ \angle ABD = 20^\circ[/tex]
So, the measure of angle ABD is 20 degrees.

A cat spends 2/3 of its life asleep. If a cat lives to be 15 years old, how many years di it spend asleep?
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

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

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
