Frank finds 9 coins on the floor of his car, and 3 of them are quarters. If he finds 15 more coins on the ground, at the same ratio as the coins found in the car, how many more coins will most likely be quarters?
Answer: 5 coins
Step-by-step explanation:
Frank found 9 coins on the floor of his car, and 3 of them were quarters. This means that 3 out of the 9 coins, or \(\frac{3}{9}\), were quarters.
Simplifying this fraction, we get \(\frac{1}{3}\) of the coins found in the car were quarters.
If Frank finds 15 more coins on the ground at the same ratio, then \(\bold{\frac{1}{3}}\) of these coins will also be quarters. To find out how many quarters he will most likely find, we need to find \(\bold{\frac{1}{3}}\) of 15:
\(\large \frac{1}{3} \times 15 = 5\)
Therefore, Frank will most likely find 5 more quarters on the ground, assuming he finds coins at the same ratio as he did in his car.

y = -6x + 7
Step-by-step explanation:
Solve the equation 25=7+r
Answer:
r = 18
Step-by-step explanation:
Subtract the seven from both sides
25 -7 = 7 - 7 + r
18 = r
Simple as that!
Hope this helps!
The solution of the given equation is 18.
The given equation is 25=7+r.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Transpose 7 to other side of the equation, we get

(For the 2nd screenshot, the options for the blanks are:
interior angles of a triangle,
vertical angles,
complementary angles,
and supplementary angles)
Answer:
photo 1: D. a + b = 180
photo 2:
a. interior angles of a triangle
b. vertical angles
c. complementary angles
d. supplementary angles
photo 3:
a. 82
b. 82
photo 4:
a. 51
b. 129
photo 5: x = 60
Step-by-step explanation:
The interior angles of a triangle are the angles that are inside the triangle and are formed by the intersection of two sides of the triangle. In a triangle, there are always three interior angles.
The sum of the interior angles of a triangle is always 180 degrees. This is because the interior angles of a triangle are supplementary, meaning that they add up to 180 degrees.
Vertical angles are two angles that are opposite each other and are formed by two intersecting lines. The lines that intersect to form the vertical angles are called "arms" of the angles.
Vertical angles are always congruent, which means that they have the same measure
Complementary angles are two angles whose measures add up to 90 degrees. In other words, if two angles are complementary, then one angle is the complement of the other.
Supplementary angles are two angles whose measures add up to 180 degrees. In other words, if two angles are supplementary, then one angle is the supplement of the other.

Amber and Jessica go out for lunch. Amber’s lunch costs $11.70, and she tips 18%. Jessica’s lunch costs $12.30, and she tips 15%. Complete a true statement.
jessica paid [ 0.29 / 0.32 / 0.55 ] , [ more/ less ] than amber at lunch
Jessica paid more than Amber at lunch.
To find out, we first need to calculate the amount of tip each person left:
Amber's tip = 11.70 x 0.18 = $2.11
Jessica's tip = 12.30 x 0.15 = $1.85
Then we add the cost of the lunch and the tip for each person:
Amber's total cost = 11.70 + 2.11 = $13.81
Jessica's total cost = 12.30 + 1.85 = $14.15
So Jessica paid $0.34 more than Amber for lunch.

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

The figure shows a trapezium PQRS where RS = 17m and PS = 15m. If PT = 14m, and the area of trapezium is 196m2, Find the length PQ.
Answer:
PQ = 11 m
Step-by-step explanation:
In trapezium PQRS,
PQ and RS are parallel lines and PT is the perpendicular distance between the parallel lines
a = PQ
b =RS = 17 m
d = PT = 14 m
\(\frac{(a+b)*d}{2}= 196\\\\\frac{(PQ + 17)*14}{2}=196\\\\(PQ + 17) * 7 = 196\\\\PQ + 17 = \frac{196}{7}\\\\PQ + 17 = 28\\\\PQ = 28 - 17\\\\PQ = 11\)

m=y2-y1/x2-x1m=-1+3/4-1m=2/3please help I don't get this at all-
Answer:
So, to start off, the two places given are, (-5.5, 2) and (2, -5.5)
The first number is described in the x plane and the second number is described in the y plane.
Firstly, you would plot -5.5 in the x and 2 in the y and see where they meet up, this is located in Quadrant Q.
Secondly, you would plot 2 in the x and -5.5 in the y and see where they meet up, this is located in Quadrant S.
Question A) The starting point is in Quadrant Q and The ending point is in Quadrant S
Question B) Since the check point is located at (5.5, 2) (which is located in Quadrant P), the main difference is that you only have to move along the x axis which means that the y stays the same but the x changes

Tom and Katherine live in different towns which are linked by a bike trail. They agree to meet for a bike ride, and both set off from home at the same time. Tom rides north at a speed of 14 mph and Katherine rides south at 10 mph. The bike trail between their homes is 42 miles long. How long will it be before they meet?
Answer:
We can start by using the formula:
time = distance / speed
Let t be the time (in hours) for Tom and Katherine to meet.
Tom's distance = Tom's speed x time = 14t
Katherine's distance = Katherine's speed x time = 10t
Since they are riding towards each other, the total distance they cover is the sum of their distances:
Tom's distance + Katherine's distance = 42 miles
14t + 10t = 42
Simplifying:
24t = 42
t = 42 / 24
t = 1.75 hours
Therefore, Tom and Katherine will meet after 1.75 hours of riding.
Which model shows the problem 1 ÷ 1 6 ?
Answer:
There's a easier way to do this just like this you keep 1/6 then you change the division into multiplication and then seance you put the five which a 1 on the bottom like this 5/1 you flip it and it's 1/5 this strategy is called keep change flip so you keep 1/6 change division into multiplication and you flip 5/1 into 1/5 so it will end up like this 1/6x1/5=1/30
so it should be 16

Harper bought 9 toys for her puppy, Peanut. The toys cost:
$9.00 $6.00 $9.00 $9.00 $6.00 $5.00 $6.00 $5.00 $3.00
What was the median price of the toys?
Answer:
$6.00
Step-by-step explanation:
As we know that the median is the middle value of a data set. When we list these costs in order:
3,5,5,6,6,6,9,9,9
When crossing out the values on each side we can see that the middle value lands on 6 so the median is $6.00
