Answer:
1020
Step-by-step explanation:
First we need to find out what 15 is so we can divide 1200 by 100 to get 12 so 1% = 12 so 15 x 12 = 180
1200-180=1020
Ms. Heinz spent 12 dollars on 30 bus tokens for
the field trip. What was the cost of 12 tokens
Answer:
4.8
Step-by-step explanation:
Firstly, you take the ratio 12d/30t(d=dollars, t=tokens). And you switch it to (unknown)d/30t. And if you execute the formula(12 * 12 / 30) you get 4.8.

Step-by-step explanation:
Josephine is in HR and believes the population mean amount of new employee hires per year in the region is greater than 64. She would like to find evidence of this claim against the standard belief that the population mean amount of new employee hires per year is exactly 64. Josephine gathers a random sample of 56 companies from the region and calculates the sample mean amount of new employees per year to be 64.79 with a sample standard deviation of 2.77. Should the pharmacist reject or fail to reject the null hypothesis given the sample data below? H0:μ=64 versus Ha:μ>64 α=0.05 (significance level) t0=2.13 0.01
Complete Question
The complete question is shown on the first uploaded image
Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The population mean is p = 64
The sample size is n = 56
The sample mean is [tex]\= x = 64.79[/tex]
The standard deviation is [tex]s = 2.77[/tex]
The null hypothesis is [tex]H_o : \mu = 64[/tex]
The alternative hypothesis is [tex]H_a : \mu > 64[/tex]
The test statistics [tex]t = 2.13[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
The p-value is [tex]0.01 < p-value < 0.025[/tex]
Given that the [tex]p-value < \alpha[/tex] we reject the null hypothesis

Question 8 (Essay Worth 2 points)
Hank is throwing a surprise party. The party costs $20 per person. Create an equation and graph to represent the relationship between the cost of the party and the number of friends attending.
Complete the following table:
Number of friends (f) 5 10 15 20
Cost of party (c) 100 200 300 400
Plots the points from the table onto the graph.
No fixed entry fee
Cost is 20$ per personIf no of persons be x
The expression is
y=20xVerification:-
100=5(20)=100Hence verified
Answer:
Let f be the number of friends
Let c be the cost of the party
As (f) is the independent variable, the number of friends will be along the x-axis.
As (c) is the dependent variable, the cost of the party will be along the y-axis.
If the cost of the party is $20 per person, then the equation to represent the relationship is:
c = 20 f

An electronic salesman wants to earn $4,000 in November. He receives a base salary of $2000 per month as well as a 10% commission for all sales in that month. How much merchandise will he have to sell to earn the amount of money he wants
20000
Based on the given conditions, formulate:
[tex](4000-2000)\div10\ percent[/tex]
Calculate
[tex]\frac{4000-2000}{0.1}[/tex]
Calculate the sum or difference
[tex]\frac{2000}{0.1}[/tex]
Multiply both the numerator and denominator with the same integer
[tex]\frac{20000}{1}[/tex]
Any fraction with a denominator of 1 is equal to its numerator
[tex]20000[/tex]
I hope this helps you
:)
Step-by-step explanation:
his salary =$2000
his commission should be (to make a total of $4000/month )=$4000-$2000 =$2000
let he should sell x amount over $7000 to get $2000 commission
So, 7% of x = 2000
7x/100 = 2000
x= (2000*100)/7 =28571.43 approx
As he will get commission on sales over $ 7000,so his should sell in a month
=$7000+$28571.43
= $ 35571.43

Answer:
[tex]1. \frac{4}{3}[/tex]
[tex]2.\frac{1}{3}[/tex]
Step-by-step explanation:
To find the scale factors, you find the length of one side from the image, and divide it by the length of the similar side in the image.
So, for #1, the image side is 8 units, and the pre-image is 6.
8/6 = 4/3
For #2, the image is 3 units, and the pre-image is 9 units.
3/9 = 1/3
Triangle ABC has vertices A(−2,10) , B(4,8) , and C(2,4) .
What are the coordinates of A′B′C′ after triangle ABC has undergone the following transformation?
rotation 90° clockwise about the origin
Enter your answers, as ordered pairs (x, y) , in the boxes.
A′=
B′=
C′=
A'=(10,2)
B'=(8,-4)
C'=(4,-2)
To rotate a point 90° clockwise about the origin,
The new coordinates become (y,-x)
So the first one was A(-2,10)
x=-2 & y=10
The new coordinates become A'(y,-x)
So y=10 and -x=-(-2)=2
A'(10,2)
Answer:
A' =(2,4)
B'=(8,2)
C′=(6,-2)
3/4(8x + 12) = -2x + 65

1.2 feet
1.4 feet
1.31 feet
1.03 feet
1.44 feet
1.5 feet

The measurements that will be dragged into the box is 1.4 feet, 1.31 feet, 1.44 feet.
The rest of the measurement wouldn't be within the bounds and thus will not be dragged in.
In a short story, a scientist spends decades working to genetically engineer a
chimpanzee that can produce human speech. Her eventual success reveals
that animals of all kinds are far smarter and more perceptive than we had
ever realized. In the end, the chimpanzee is
released into the wild and the
scientist's work erased because humans are not comfortable with this
knowledge.
What are two common literary themes that this story most clearly shows?
• A. The determination to succeed and the acceptance of failure
• B. The domination of man over nature and unrealized dreams
• C. The complexity of nature and the security of ignorance
• D. The power of
science and the evil of humankind
Answer:
C
Step-by-step explanation:
it’s just unnatural for a wild animal to give a speech. The security of ignorance is when humans are uncomfortable with it.

Determine the equation of the line containing the points given in the table below.
Answer:
BTW where is the table??2k+8=0 Can someone help explain how to solves this please?
Answer:
2k + 8 = 0
2k + 8 - 8 = 0 - 8
2k = - 8
2k/2 = - 8/2
k = - 4
Step-by-step explanation:
you gotta put the 8 on the other side by subtracting and the divide both sides to get k
Answer:
k = -4
Step-by-step explanation:
2k + 8 = 0
Subtract 8 from both sides.
2k = -8
Divide both sides by 2.
k = -4

Answer:
C. 72
Step-by-step explanation:
The whole angle measures 106 degrees as mentioned on top and we know that angle HFG is 34 degrees because it says so in that angle. Just do this: 106-34. The answer is 72. We subtract because we're finding the remaining/missing number in this problem. If you want to check if your answer is correct, you can add 72 and 34.
Another way you could do this is by just adding each option with 34 to see if you get a total of 106.

Find the measure of angle a.
a
50°
Answer:
the measure of angle is m(<a)=40
Step-by-step explanation:
the intirior angles of all triangles add up to 180
with this you can subtract the 90 degree angle and the 50 degree angle from the total of 180 degrees.
180
90
-50
---------
=40 degreese
hoped this helped.
Step-by-step explanation:
a+50+90=180°(being sum of angle of right angled▲)
or, a+140= 180°
or, a=180°_ 140°
Therefore, a=40°

Answer:
y = 5
x = 0
Step-by-step explanation:
soo i think elimination was this:
so first lets make -x = 3x
so we multiply -3 to the whole equation
3x + 3y = 15
now we eliminate (i think this is elimination)
3x + 5y = 25
-
3x + 3y = 15
----------------------------
0 + 2y = 10
2y = 10
y = 5
now substitute to one of the original equations
3x + 5(5) = 25
3x + 25 = 25
3x = 0
x = 0
now lets check
-0 -5 = -5?
-5 = -5

Willy can cover in 1L paint
[tex]\\ \rm\rightarrowtail \dfrac{13.5}{3}=4.5m^2[/tex]
1st box should be filled with 4.5Can cover in 10L
[tex]\\ \rm\rightarrowtail 4.5(10)=45m^2[/tex]
Second one should be filled with 45
Answer:
4.5 : 1
45 : 10
Step-by-step explanation:
Given ratio: 13.5 : 3
To calculate equivalent ratios, we need to do the same operation to both sides of the ratio.
To reduce 3 L of paint to 1 L of paint, we need to divide by 3.
Therefore, we should also divide 13.5 by 3:
13.5 ÷ 3 : 3 ÷ 3
= 4.5 : 1
To increase 1 L of paint to 10 L of paint, we need to multiply by 10:
4.5 × 10 : 1 × 10
= 45 : 10
which would be the right one????

The number of children Mr. Smith has can be determined by using the skill of logical reasoning.
Mr Smith has at least one son.He also has at least two daughters.Assuming that son has two brothers, then he also has two sisters.
Each sister has one sister and three brothers.
This scenario does not satisfy the conditions.
Assuming that son has three brothers, then he also has three sisters.
Each sister has two sisters and four brothers.
