Answer:
Amount Noah spent on cappuccino for that week = $22.95
Step-by-step explanation:
Noah pays $7.65 for a cappuccino on days he's running late to work
Cost of cappuccino per day = $7.65
One week, he was late on Monday, Wednesday, and Friday.
That is 3 days in a week
How much did he spend (in $) on cappuccinos that week? $
Amount Noah spent on cappuccino = cost of cappuccino per day × 3 days
= $7.65 × 3
= $22.95
Amount spent on cappuccino for that week = $22.95

Store A charges $1,200 for repairs with a 6 percent sales tax. Store B charges $1,350 with a 7 percent sales tax. Explain how you would determine the amount of money saved by using Store A instead of Store B?
Step-by-step explanation:
Store A:
6% of 1,200 is 72
72 + 1,200 = 1,272
Thus, store A has a total of 1,272
Store B:
7% of 1,350 is 94.5
94.5 + 1,350 = 1444.5
Thus, Store B has a total of 1444.5
1444.5 - 1,272 = 172.5
Thus, Store A is cheaper.
Answer:
sales tax- rate×original amount
A- 6/100(1200)=72
B- 7/100(1350)=94.5

What is the difference between ordering numbers, comparing numbers, and comparing amounts?
Answer:
different definitions
Step-by-step explanation:
ordering numbers can be seen as arranging the numbers by a certain characteristics. for example, you could order numbers from least to greatest
comparing numbers can be seen as looking into two or more numbers rather than the entire group of numbers. for example, if there were the numbers 1, 2, 3, 4, 5, 6, you could say that 2, 4, 6, are even numbers
comparing amounts could be determined by worth but not the numerical values. for example, you could have a gallon of milk and a quart of orange juice but just by the size of the container, a gallon of milk is bigger and holds more than a quart of orange juice

Graph y < -x - 1, I do not understand what to do without a slope given.
Answer:
Step-by-step explanation:
If you are not given a number before x always assume it is a 1 and if there are no visible denominators also assume that it is 1
In this case the inequality reads y<-1x/1-1
The slope is -1/1x or fall 1 crawl 1
The y-intercept is -1
I looked up the graph...
5y + 10x = 0
y = - 3x

A pet store has 40 animals for sale and 15 of them are puppies what is the ratio of animals that are not puppies to the total number of animals for sale at the pet stor
Answer: 5:8
Step-by-step explanation:
Given: Total animals in the pet store = 40
Number of animals that are puppies= 15
Number of animals that are not puppies= 40- 15 = 25
Now , the ratio of A to B = [tex]\dfrac{A}{B}[/tex] or A : B.
So, the ratio of animals that are not puppies to the total number of animals for sale at the pet store = [tex]\dfrac{25}{40}[/tex]
Divide numerator and denominator by 5 , we get [tex]\ \ \ \dfrac{5}{8}[/tex].
Hence, the required ratio = 5:8

In right triangle XYZ, the tangent of acute angle X is 4. What is the secant of angle X?
Answer:
The secant of angle x; sec x = √17
Step-by-step explanation:
Here, given the tangent of an angle, we want to find the value of the secant
Mathematically;
sec^2 x = 1 + tan^2 x
This is from trigonometric identity
Thus;
sec x = √(1 + tan^2 x)
According to the question;
tan x = 4
So tan^2 x = 4^2 = 16
Thus;
sec x = √1 + 4^2
sec x = √17

2. An electric fan has a resistance of 3.0 kN and a voltage rating of 220 volts. What
is the current needed to operate the electric fan?
Given:
Resistance (R)
ka x (1000/1 kg) =
volts
Voltage (V)
Required: Current (1)
Formula:
voltage
resistance
Solution:
V-IR
Answer:
Current =
A, the current needed to operate
the electric fan
Answer: 73.33A
Step-by-step explanation:
Resistance (R)= 3.0 kN
Voltage (V)= 220 volts
Current (I)= Unknown
The formula to calculate the current will be:
Current = Voltage / Resistance
Current = 220 / 3.0
Current = 73.33 A
Therefore, the current needed to operate the electric fan is 73.33.

Answer:
See below.
Step-by-step explanation:

E(1, 2), F(5, 6), G(3, -2)
a)
H, midpoint of segment EG
H( (1 + 3)/2, (2 + (-2))/2) = H(2, 0)
J, midpoint of segment FG
J( (5 + 3)/2, (6 + (-2))/2) = J(4, 2)
b)
Show that segment HJ is parallel to segment EF.
Parallel lines have equal slopes. We find the slopes of the two segments using the endpoints and show that the slopes are equal proving the segments are parallel.
slope of segment HJ:
slope HJ = (2 - 0)/(4 - 2) = 2/2 = 1
slope of segment EF:
slope EF = (6 - 2)/(5 - 1) = 4/4 = 1
slope HJ = slope EF = 1
Segments HJ and EF are parallel since their slopes are equal.
c)
Show HJ = (1/2)EF
We use the distance formula to find the lengths of segments HJ and EF.
length of HJ = sqrt[(4 - 2)^2 + (2 - 0)^2] = sqrt(4 + 4) = sqrt(8) = 2sqrt(2)
length of EF = sqrt[(5 - 1)^2 + (6 - 2)^2] = sqrt(16 + 16) = sqrt(32) = 4sqrt(2)
HJ = (1/2)EF
Substitute the lengths we found just above for HJ and EF:
2sqrt(2) = (1/2)[4sqrt(2)]
2sqrt(2) = 2sqrt(2)
The two sides are equal, so we have proved that HJ = (1/2)EF.
