Answer: 1. $45*1.07 | $45(1.07) 2. (0.85)*32 represent the final price of the cake in dollars because (0.85) is the 15% off in decimals.
Step-by-step explanation:
1 if you multiply 45 by 1.07 it will be 48.15 and that's the final cost of the book, same with $45(1.07) is just another way to represent the multiplication.
2 As I said the 0.85 represent the 15% off, and when you multiply it will be less.
3m-19=14
what it be???
Answer:
m=11
Step-by-step explanation:
Add 19 to both sides.
3m−19+19=14+19
3m=33
Divide both sides by 3.
3m/3=33/3
m=11
Answer:
m=11
Step-by-step explanation:
We want to isolate m on the left side of the equation.
3m-19=14; add 19 to both sides, now you have:
3m=33; divide 33 by 3:
m=11
The number of sunflowers (s) in the garden is one more
than twice the number of roses (r):
is it inequality it not
what's its inequality model—×??
Answer:
s = 2r + 1
Step-by-step explanation:
Number of sunflower (s) is 1 more than twice the number of roses (r)
Mathematically ;
Number of sunflower = 1 + 2 * number of roses
Sunflower = s ; roses = r
s = 2r + 1
We want to study the relation between the number of sunflowers and roses, we will see that it is an equation and the equation is:
s = 2*r + 1
So we know that the number of sunflowers is one more than twice the number of roses, notice that it represents an equation (so it is not an inequality)
And the equation can be written as:
s = 2*r + 1
The number of sunflowers is 2 times the number of roses, plus 1.

A data set consists of 2, 2, 3, 4, 5, 5, and 7. Then, 20 is added to the data set. The new value will have little effect on the , but it will raise the significantly.
Answer:
Median; mean.
Step-by-step explanation:
A data set consists of 2, 2, 3, 4, 5, 5, and 7. Then, 20 is added to the data set. The new value will have little effect on the median, but it will raise the mean significantly.
Let's find the median and mean from the original data;
x = 2, 2, 3, 4, 5, 5, 7.
F(x) = 2 + 2 + 3 + 4 + 5 + 5 + 7
F(x) = 28
[tex] Mean = \frac {F(x)}{7} [/tex]
[tex] Mean = \frac {28}{7} [/tex]
Mean = 4
Median is the middle number of a sorted array of numbers.
Median = 4
Now, let's find the median and mean from the new data;
x = 2, 2, 3, 4, 5, 5, 7, 20.
F(x) = 2 + 2 + 3 + 4 + 5 + 5 + 7 + 20
F(x) = 48
[tex] Mean = \frac {48}{6} [/tex]
Mean = 8
[tex] Median = \frac {4 + 5}{2} [/tex]
Median = 4.5
Therefore, the median increased from 4 to 4.5 while the mean increased significantly from 4 to 8.
a certain state the license plate has two digits, then two letters, and then two digits. How many different license plates are possible if letters and digits cannot be repeated?
Step-by-step explanation:
Choosing 4 digits out of 10 = 10C4 = 210.
Arranging the 4 digits in 4 places = 4!
Total number of ways to arrange digits
= 210 * 4! = 5040.
Choosing 2 letters out of 26 = 26C2 = 325
Arranging the 2 letters in 2 places = 2!
Total number of ways to arrange letters
= 325 * 2! = 650.
Total number of possible license plates
= 5040 * 650 = 3,276,000.
Answer:
3,276,000
Step-by-step explanation:
10 x 9 x 26 x 25 x 8 x 7 = 3,276,000
the numbers 10, 9, 8, 7 are the spaces available for a non-duplicated digit
the numbers 26 and 25 are for two non-duplicated letters

Lattice has £15000 in a savings account at the start of the year. How much will she have at the end of the year if the annual interest rate is 7.5%?
Answer:
£13 875
Step-by-step explanation:
first you have to find out how much is 7.5% of 15 000 and you find it by calculating 0,075 times 15 000 which becomes 1 125. then you take out that answer from your first answer which is 15 000 - 1 125= 13 875

A type of electric car can travel 5 on 1 kilowatt hour of electricity. How many kilowatt hours of electricity would it take Helen to drive her electric car to her aunts house and back? Helen lives 70 miles from her aunt.
Answer:
28 kwh
Step-by-step explanation:
given that the care can travel 5 miles on 1 kwh, i.e
5 miles travelled -----> uses 1 kwh
hence to find the unit rate:
1 mile travelled ----> Uses 1 kwh ÷ 5 = 1/5 kwh
We are also given that Helen lives 70 miles away from her aunt.
Hence a return trip (i.e "to aunts house and back"), will be 70 x 2 = 140 miles
using the unit rate that we found above, we can find the number of kwh that is used to travel 140 miles
140 miles = 140 miles x unit rate
= 140 x 1/5
= 28 kwh
Is the function linear or non linear?
Answer:
The function Has to Be Linear.
Step-by-step explanation:
The reason why the function has to be linear is because even though there is a slight curve the rest of the line is straight.
You need to look at the direction the line is pointing. Now say it was a line that had all kinds of wavey curves and loops that would be nonlinear.
I hope this helps you out. Let me know if linear is the correct answer, because if it isn't then that Assessment is crazy.

What is Polygon?A polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain.
We are given the measures of six angles in the heptagon, which are:
95, 107, 132, 138, 145, and 158 degrees
Sum of angles in Heptagon is 900 degrees.
To find the measure of the seventh angle, we can subtract the sum of the six known angles from the sum of all the angles in the heptagon:
Measure of the seventh angle = Sum of angles - Sum of known angles
Measure of the seventh angle = 900 degrees - (95 + 107 + 132 + 138 + 145 + 158) degrees
Measure of the seventh angle = 900 degrees - 775 degrees
Measure of the seventh angle = 125 degrees
Therefore, the measure of the seventh angle in the heptagon is 125 degrees.

The crew is taking 80 liters of water. There are 4 people on the crew. How many milliliters of water does each person get?
Answer:
Each people get 20,000 mili-litres of water.
Step-by-step explanation:
As , we know that
1 litre = 1000 mili-litre
As we have 80 litre of water
⇒ 80 litres = 80×1000 mili-litres
= 80,000 mili-litres
⇒ 80 litres = 80,000 mili-litres
∴ we have
Total water available in the crew = 80,000 mili-litres
As , there are 4 people in the crew
Let each people consume x mili-litre
⇒4x = 80,000 mili-litres
⇒x = [tex]\frac{80,000}{4} = 20,000[/tex] mili-litres
∴ we get
Each people gets 20,000 mili-litres of water.
