Answer:
Yes! C=10+35h is correct!
Step-by-step explanation:
Yes, equation is correct!
$10 is fixed one time fee.$35 is hourly pay.
So, if she needs tutor for 'h' hours, the variable cost is $35h
So, total cost C =10+35h
Question 1 (1 point) A locksmith charges $25 to make a house call and $15 for each lock re-keyed. Another locksmith charges $10 to make a house call and $20 for each lock that is re-keyed. Write a system of equations and use them to determine the number of locks where the total cost is the same. What will be the total cost? (Hint: write 2 equations of the form y = mx + b)
Answer:
The number of locks will be 3
The total cost = $50
Step-by-step explanation:
We are trying to write the equations of the cost in the form of the equation of a straight line
The equation will be;
C = F + 15r
where F is the price for house lock , C is total cost and r is the amount per rekey
For the first locksmith;
His equation will be ;
C = 25 + 15r
For the second
C = 10 + 20r
If the total cost is the same for both;
then;
10 + 20r = 25 + 15r
20r - 15r = 25 - 10
5r = 15
r = 15/5 = 3
For the total cost to be same, number of locks is 3
The total cost will be ;
C = 20 + 10(3) = 20 + 30 = $50

Answer:
[tex]4\pi[/tex]
Step-by-step explanation:
S = Arc Lenth
θ = Radians
R = Radius
S = θR
So, now that we understand the formula, we will convert 72° into radians by introducing the equation [tex]x*\frac{\pi }{180}[/tex], x = 72
S = [tex]72*\frac{\pi }{180} * R[/tex]
given that R = 10
S = [tex]\frac{72*10*\pi }{180}[/tex]
S = [tex]\frac{720*\pi }{180}[/tex]
We simplify 720 as 180 goes into 720 4 times and we get
S = [tex]4\pi[/tex]

you and 13 of your friends play on a softball team.a sponsor paid for the league fee each player's t-shirt new box for the team and tuna softballs for each game of the season does expression that represents the total amount (in dollars) paid by the sponsor is 14x + 20 (2 y +) + 5 Z + 120.
a. which at a represents the league fee? Explain your reasoning
b. Which added represents the T-shirt? Explain your reasoning.
c. What does y represent?
The expression of the league fee is an algebraic expression
The expression that represents the league fee is 14x
How to determine the league fee?The expression is given as:
14x + 20(2y + ) 5z + 10
The expression is not properly stated;
Only the league fee can be deducted from the given expression.
From the question, we understand that there are 14 players in total
i.e you (1) and (13) others
This means that the total league fee for the 14 players is:
Total = 14 * League fee for each player.
One of the terms of the expression is 14x.
So, we have:
14 * League fee for each player. = 14x
Hence, the expression that represents the league fee is 14x

the angle of elevation to the sun is 24°. what is the length of the shadow cast by a person 1.82 m tall?
Answer:
4.089
Step-by-step explanation:
24 degree is the Angle of elevation. SO we can use in this triangle Tan.
So tan 24 = AB/BC because tan is the ratio of height over adjacent.
So we can say it is tan 24 = (1.82)/BC
So BC = (1.82)/tan(24) = 4.089m
BC is representing shadow of men. So shadow of men is 4.089m

Making X Subject of the formula
we have,
X= 7×4 = 28 = 14 = 7
12 12 6 3
OR
You cross multiply
X multiplies 12= 12X
7 multiplies 4= 28
you now have 12X=28
divinding both sides by 12,
12 cancels 12 and leave X
Answer:
x = [tex]\frac{7}{3}[/tex]
Step-by-step explanation:
[tex]\frac{x}{4}[/tex] = [tex]\frac{7}{12}[/tex] ( cross- multiply )
12x = 28 ( divide both sides by 12 )
x = [tex]\frac{28}{12}[/tex] = [tex]\frac{7}{3}[/tex] ← in simplest form
Mrs Atkins is going to choose two students from her class to take part in a competition.
She can choose from 16 girls and 14 boys.
(a)
Work out the number of different ways of choosing one girl and one boy.
Given:
Total number of girls in her class = 16
Total number of boys in her class = 14
To find:
The number of different ways of choosing one girl and one boy.
Solution:
We have,
Total number of girls = 16
Total number of boys = 14
So,
Total number of ways to select one girl from 16 girls = 16
Total number of ways to select one boy from 14 boys = 14
Now, number of different ways of choosing one girl and one boy is
[tex]16\times 14=224[/tex]
Therefore, the required number of different ways is 224.
a. The number of different ways of choosing one girl and one boy is 226
Calculation:Total number of ways to select one girl from 16 girls = 16
Total number of ways to select one boy from 14 boys = 14
So, the number should be
[tex]= 16 \times 14[/tex]
= 224

Is the square root of 105 closer to 10 or 11. Explain?
Answer:
You can say that √105 is somewhere between 10 and 11 because 105 lies between the squares of 10 and 11 (100 and 121, respectively). However, 105 isn't a perfect square, so you can't really find its exact square root. If you have a calculator with you, you can solve for an approximate of √105 which is 10.246950766.

Using Euclid's algorithm, find the HCF of 1651 and 2032. Express
the HCF in the form (1651m + 2032n) for some integers m and n.
Answer:
Since 2032 gt 1651, we divide 2032 by 1651 to get 1 as quotient and 381 as remainder. step 2. Since the remainder 381≠0 , we divide 1651 by 381 to get 4 as quotient and 127 as remainder.
Step-by-step explanation:
Euclid algorithm lemma, a = bq + r where 0 ≤ r < b
From Euclid algorithm lemma, 2032 = 1651 × 1 + 381
Using lemma for 1651 and 381, e.g., 1651 = 381 × 4 + 127
Similarly, use lemma for 381 and 127, e.g., 381 = 127 × 3 + 0
Hence, HCF = 127
Now, 127 = 1651M + 2032 N
⇒127 = (127 × 13)M + (127 × 16)M
⇒1 = 13M + 16 N
Here many solutions possible because we have one equation contains two variable.
Assume M = 5 and N = -4
Then, 13 × 5 + 16 × -4 = 65 – 64 = 1
So, HCF of 1651 and 2032 in the form of 1651M + 2032 N is [1651(5) + 2032(-4)]

What is the solution to the equation? x = 10 x = 12 x = 15 x = 30 What is the fee Michael charges each new subscriber?
Answer:
x=12
Step-by-step explanation:
For the given situation , a quantity x is added to [tex]\frac{1}{4} x[/tex] gives 15.
We can set up equation as
[tex]x+\frac{1}{4}x=15[/tex]
Multiply each term by 4 on both sides to get rid the denominator.
It gives,
4 x+x=60
Now, combine like terms
5 x=60
Divide both sides by 5
x=12.

Answer:
43.1
Step-by-step explanation:
Similar shapes have sides of the same proportions. This means that one shape is just an enlargement of the other.
In this case, triangle MNO is an enlargement of triangle JKL so we can work out a scale factor.
To work out the scale factor, we can do 58.8 ÷ 15 = 3.92. To find side NO, all we have to do is multiply 11 by 3.92 to get 43.12 ≈ 43.1 (rounded to the nearest tenth).

Maria is trying to estimate 30. She uses this table of values
What should she do next to find 30 to the nearest hundredth?
A. She should find the squares of numbers between 5.5 and 5.6.
B. She should estimate that 30 is 5.50.
C. She should find the squares of numbers between 5.4 and 5.5.
D. She should find the average of 5.4 and 5.5.
The correct answer for the given question is C. She should find the squares of numbers between 5.4 and 5.5.
What is square of a number?Square of a number is the product of integer with itself.
Now it is given that Maria is trying to estimate 30.
To find the value of 30 let us take the root of 30.
So, √30 = 5.4772
Since 7 to the right of 7 is greater than 5
Round to the nearest hundredth,
√30 = 5.48
Hence, 5.48 is the nearest square of 30.
From the table we see that the nearest digit to the 30 is 5.4² and 5.5²
The value of 5.4² given in the table is 29.2.
and the value of 5.5² given in the table is 30.3.
Hence,she should do next to find 30 to the nearest hundredth is to find the squares of numbers between 5.4 and 5.5.
Therefore,The correct answer is C. She should find the squares of numbers between 5.4 and 5.5.
