Tiffany spent 30 minutes on math homework and 15 minutes on science homework. What is the ratio of the minutes she spent on math homework compared to the minutes she spent on science homework?
Answer: The ratio would be 30/15, simplified as 2/1. So, she spent half as much time on science, or twice as much on math.

The scale on a map is 4 cm = 25 miles. Dave measures the distance to the next town at 9 cm. How many miles away is the next town?
Answer:
58.333....
Step-by-step explanation:
8cm=50
1cm so 25/3
8.3333333333
Answer:
56.25 or 56 1/4
Step-by-step explanation:
If 4 cm is equal to 25 miles then we can divide 25 by 4 to see how many miles is in 1 cm.
25 divided by 4 is 6.25 or 6 1/4
Therefor 1 cm is equal to 6.25 miles.
Now we multiply 9 by 6.25 to get 56.25
For each year that a gift card goes unused, the value of the card decreases by 5%. What is the value of a $25.00 gift card after 1 year? Show your work.
Answer:
25*0.95 = 23.75
Step-by-step explanation:
i multiplied by 0.95 because the card is still worth 95% of it's original worth.
you could've done:
25*0.05= 1.75 and then subtract that from 25 to get 23.75, i just find the other way easier.
i hope this helped :)

Step-by-step explanation:
-2x - (-18x + 126) = -18
-2x + 18x - 126 = -18
16x = -18 + 126
16x = 108

Answer:
c= 89
Step-by-step explanation:
the angles of a triangle add up to 180
in this triangle, our angles are:
c-33
c-25
c-29
this means that
(c-33) + (c-25) + (c-29) = 180
3c - 87 = 180
add 87 to both sides
3c = 267
divide both sides by 3
c = 89
Given that f(x)=2x+1
a) find f(2)
b)find f^-1(x)
c)f^-1(7)
Answer:
a) [tex]f(2) = 5[/tex], b) [tex]f^{-1} (x) = \frac{x-1}{2}[/tex], c) [tex]f^{-1} (7) = 3[/tex]
Step-by-step explanation:
a) We evaluate the function at [tex]x = 2[/tex]:
[tex]f(2) = 2\cdot (2) + 1[/tex]
[tex]f(2) = 4+1[/tex]
[tex]f(2) = 5[/tex]
b) First, we determine the inverse of the function by algebraic means:
1) [tex]y = 2\cdot x + 1[/tex] Given
2) [tex]y +(-1) = 2\cdot x + [1+(-1)][/tex] Compatibility with addition/Associative property
3) [tex]y + (-1) =2\cdot x[/tex] Existence of additive inverse/Modulative property
4) [tex]2^{-1}\cdot [y+(-1)] = (2\cdot 2^{-1})\cdot x[/tex] Compatibility with multiplication/Commutative and associative properties
5) [tex][y+(-1)]\cdot 2^{-1} = x[/tex] Existence of multiplicative inverse/Modulative and commutative properties
6) [tex]x = [y+(-1)]\cdot 2^{-1}[/tex] Symmetry property of equality
7) [tex]x = \frac{y-1}{2}[/tex] Definitions of subtraction and division
8) [tex]f^{-1} (x) = \frac{x-1}{2}[/tex] [tex]x = f_{-1} (x)[/tex]/[tex]y = x[/tex]/Result
c) Now we evaluate the expression obtained on b) at the given number:
[tex]f^{-1} (7) = \frac{7-1}{2}[/tex]
[tex]f^{-1} (7) = 3[/tex]

There are 3 teachers to 125 pupils during the school program. How many teachers were
there if there were 2 500 pupils
Answer:
There were 60 teachers.
Step-by-step explanation:
☆We can use proportion to solve this!
[tex] \frac{3 \: teachers}{125 \: pupils} = \frac{x}{2500 \: pupils} \\ \\ \frac{125x}{125} = \frac{7500}{125} \\ \\ x = 60[/tex]

Jada had some dimes and quarters that had a total value of $12.50. The relationship between the number of dimes, d, and the number of quarters, q, can be expressed by the equation 01.d+0.25q= 12.5.
Question 1 - 1 pts
If Jada has 4 quarters, how many dimes does she have?
Question 2 - 1 pts
If Jada has 10 quarters, how many dimes does she have?
Question 3 - 1 pts
Is the number of dimes a function of the number of quarters? If yes, write a rule (that starts with d =...) that you can use to determine the output, d, from a given input, q. If no, explain why not.
Question 4 - 1 pts
If Jada has 25 dimes, how many quarters does she have?
Question 5 - 1 pts
If Jada has 30 dimes, how many quarters does she have?

Is the following statement true or false?
The triangle proportionality theorem only applies to right triangles.
A.) False
B.) True
Answer:
A.) False
Step-by-step explanation:
The triangle proportionality theorem can apply to all triangles, because if a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally. This situation does not just apply to right triangles.
Answer:
I think it's actually True
Step-by-step explanation:
The triangle proportionality theorem can apply to all triangles, because if a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally. This situation does not just apply to right triangles.

Which of the following correctly uses absolute value to show the distance between -80 and 15? (5 points)
a
|-80 - 15| = |-95| = -95 units
b
|-80 + 15| = |-65| = 65 units
c
|-80 - 15| = |-95| = 95 units
d
|-80 + 15| = |-65| = -65 units
Answer:
it's answer is b
|-80+15| = |-65| = 65 units
Hope this helps :)

Answer:

Hanna's typing speed is one word fewer than that of Becky's speed.
What is the general equation of a Straight line? What is equation modelling?The general equation of a straight line is -
y = mx + c[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given are Hannah and Becky, who are learning to type on a computer keyboard. Hanna's typing speed is represented by the equation y = 11z. Becky's typing speed is given by the graph as shown in the question.
Now, for Hanna, her typing speed would be -
11 words per minute
For Becky, the slope of the graph will be -
m = (24 - 12)/(2 - 1)
m = 12
12 words per minute
It can be seen easily that Hanna's typing speed is one word fewer than that of Becky's speed.
Therefore, Hanna's typing speed is one word fewer than that of Becky's speed.

Answer:
the thrid one
Step-by-step explanation:
The table that shows a function that is decreasing only over the interval (-1, oo) is table 3
For a table to show a decreasing interval, then the table values must reduce as the x value increase
The interval (-1, oo) means that, -1 is exclusive of the x values.
So, we start from x > -1
The first table shows an increasing function for x > -1
The second table shows an increasing and decreasing function for x > -1
The third table shows a decreasing function for x > -1
The last table shows a decreasing function for x > -1 but increases at other values
Hence, the table that shows a function that is decreasing only over the interval (-1, oo) is table 3

Ling earns $8 per hour working at the zoo. Write and solve an inequality that can be used to find how many hours she must work in a week to earn at least $120. Interpret the solution.
Answer:
Ling should atleast work 15 hours a week to earn $120.
Step-by-step explanation:
Ling earn per hour = $8
Let the number of hours she worked to be x.
Now, inequality =
[tex]8x \geq 120[/tex]
Dividing both side by 8.
[tex]\dfrac{8x}{8} \geq \dfrac{120}{8}[/tex]
[tex]x \geq 15[/tex]
Hence, Ling should atleast work 15 hours a week to earn $120.
