Answer:
85%
Step-by-step explanation:
Evan had 120 baseball cards. He gave 18 of them to his friend and the rest to his brother.
The number of baseball cards he gave to his brother is :
120 - 18 = 102 baseball cards
The percent of the baseball cards he gave to his brother is calculated as:
(Number of baseball cards given to his brother/ Total number of baseball cards) × 100
= 102/120 × 100
= 85%
The percent of baseball cards Evans gave his brother is 85%

There are 80 cups of water in 5 gallons of water. What is the total number of cups of water in one half-gallon of water?
Answer:
8 cups
Step-by-step explanation:
Answer:
8 Cups
Step-by-step explanation:
The first thing you do is divide 80 by 5 and it will give you 16. It says one half gallon so 16 is for a full gallon so you will end up dividing 16 by 2 and get eight.
A group of 106 campers sits in a big circle. The camp leader tells them to say "hello" to each camper sitting to their left and right. What is the total number of times the campers say "hello"?
Given :
A group of 106 campers sits in a big circle.
The camp leader tells them to say "hello" to each camper sitting to their left and right.
To Find :
What is the total number of times the campers say "hello".
Solution :
It is given that each camper say "hello" to each camper sitting to their left and right i.e each camper says "hello" twice.
Therefore, 106 campers will say hello = 106 × 2 = 212 times.
Hence, this is the required solution.
-10=-b/4 can some on pls help me
Answer:
b = 40
Step-by-step explanation:
The first step you have to do is multiply 4 on each side to cancel out the 4 under -b, so you can get b by itself.
4 x -10 = -b x 4 should get this -40 = -b
4
Now the final step is to divide -1 on each side to cancel out the negative by b, thus getting b by itself. Then once that is done you will see that your answer is b=40.
-40 = -b should get this 40=b or b=40
-1 -1

In the accompanying diagram of triangle XYZ and triangle ABC, angle X cong angle A and angle Y cong angle B . If XY = 5 , YZ = 12 , and AB = 15 , what is BC? A 15X 5 Y12B с
Answer:
BC = 36
Step-by-step explanation:
If <X ≅ <A, and <Y ≅ B, therefore ∆XYZ is similar to ∆ABC.
Since ∆XYZ is similar to ∆ABC, it follows that the ration of their corresponding side lengths would be equal.
That is:
[tex] \frac{AB}{XY} = \frac{BC}{YZ} = \frac{AC}{XZ} [/tex]
AB = 15
XY = 5
YZ = 12
Thus:
[tex] \frac{AB}{XY} = \frac{BC}{YZ} [/tex]
Plug in the values
[tex] \frac{15}{5} = \frac{BC}{12} [/tex]
Multiply both sides by 12
[tex] \frac{15}{5}*12 = \frac{BC}{12}*12 [/tex]
[tex] \frac{15*12}{5} = BC [/tex]
[tex] 36 = BC [/tex]
The length of the segment BC is 36 and this can be determined by using similar triangle properties and the given data.
Given :
Angle X congruent to angle A and angle Y congruent to angle B. XY = 5 , YZ = 12 , and AB = 15.The following steps can be used in order to determine the length of the segment BC:
Step 1 - According to the given data, XY = 5 , YZ = 12 , and AB = 15. Also angle X congruent to angle A and angle Y congruent to angle B.
Step 2 - So, according to the given data, it can be concluded that both the triangles are similar.
Step 3 - From the above steps, it can be concluded that the corresponding sides ratios of the triangles are equal.
[tex]\rm \dfrac{AB}{XY}=\dfrac{BC}{YZ}=\dfrac{AC}{XZ}[/tex]
Step 4 - Now, substitute the values of YZ, XY, and AB in the above expression.
[tex]\rm \dfrac{15}{5}=\dfrac{BC}{12}[/tex]
Step 5 - Simplify the above expression.
BC = 36

You are traveling in a car and you want to know how long it will take you to reach your destination. You will travel 220 miles at an average speed of 55 miles per hour. Use the distance formula D=r•t , to determine how much time, t, in hours it will take you to get there
Answer:
You will get there in 4 hours
Step-by-step explanation:
Use the distance formula D=r•t , to determine how much time, t, in hours it will take you to get there
Where D = Distance
r = rate = Average Speed
t = time in hours
From the question
D = 220 miles
t = ??
r = 55 miles/hour
Hence:
220miles = 55miles/hour × t
t = 220/55
t = 4 hours
You will get there in 4 hours

The arithmetic sequence a_ia i a, start subscript, i, end subscript is defined by the formula: a_1 = 15a 1 =15a, start subscript, 1, end subscript, equals, 15 a_i = a_{i - 1} -7a i =a i−1 −7a, start subscript, i, end subscript, equals, a, start subscript, i, minus, 1, end subscript, minus, 7 Find the sum of the first 660660660 terms in the sequence.
Answer:
-1,512,390
Step-by-step explanation:
Given
a1 = 15
[tex]a_i = a_{i-1} -7[/tex]
Let us generate the first three terms of the sequence
[tex]a_2 = a_{2-1}-7\\a_2 = a_1 - 7\\a_2 = 15-7\\a_2 = 8[/tex]
For [tex]a_3[/tex]
[tex]a_3 = a_{3-1}-7\\a_3 = a_2 - 7\\a_3 = 8-7\\a_3 = 1[/tex]
Hence the first three terms ae 15, 8, 1...
This sequence forms an arithmetic progression with;
first term a = 15
common difference d = 8 - 15 = - -8 = -7
n is the number of terms = 660 (since we are looking for the sum of the first 660 terms)
Using the formula;
[tex]S_n = \frac{n}{2}[2a + (n-1)d]\\[/tex]
Substitute the given values;
[tex]S_{660} = \frac{660}{2}[2(15) + (660-1)(-7)]\\S_{660} = 330[30 + (659)(-7)]\\S_{660} = 330[30 -4613]\\S_{660} = 330[-4583]\\S_{660} = -1,512,390[/tex]
Hence the sum of the first 660 terms of the sequence is -1,512,390

Explain how you might go from gallons to cups using more than one conversion factor.
Answer:
13
Step-by-step explanation:
Answer:
Remember this conversion factor:
1 U.S. customary cup = 0.0625 U.S. gallons
Step 2:
Let's pretend that you are converting 100 cups to gallons. To do this, simply multiply the number of cups you have by 0.0625 like so:
100 cups x 0.0625 gallons/cup
Solution
100 cups x 0.0625 gallons/cup = 6.25 gallons

The coordinate plane has the following points A=(2, 1), B=(5, 1), C=(7,2), and 1 point
D=(4,2). What is the length of CD?
Answer:
d = 3
Step-by-step explanation:
Coordinate Plane
The image provided shows the four points given:
A=(2, 1), B=(5, 1), C=(7,2), D=(4,2).
It can be clearly seen the length of CD is just the difference of their x-coordinates:
CD = 7 - 4 = 3
We can also use the formula of the distance.
Given two points C(x,y) and D(w,z), the distance between them is:
[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]
[tex]d=\sqrt{(2-2)^2+(7-4)^2}[/tex]

Ferrell has 9 nickels and some quarters in his pocket. The value of his coins is $3.70. Which equation can be used to find the number of quarters, q, Farrell has in his pocket?
Answer:
[tex]0.45 + 0.25q = 3.70[/tex]
Step-by-step explanation:
Given that:
Number of nickels with Ferrell = 9
Number of quarters = [tex]q[/tex]
Value of coins = $3.70
To find:
The equation to find the number of quarters.
Solution:
Value of a nickel = 5 quarters = $0.05
Value of 9 nickels = [tex]9 \times 0.05 = \$ 0.45[/tex]
Value of a quarter = $0.25
Value of [tex]q[/tex] quarters = $0.25[tex]q[/tex]
Total value of coins = Value of 9 nickels + Value of [tex]q[/tex] quarters[tex]\$0.45 + \$0.25q = \$3.70\\\Rightarrow 0.25q=3.70-0.45\\\Rightarrow 0.25q=3.25\\\Rightarrow q =13[/tex]
So, the answer is, number of quarters available with Ferrell = 13
The equation to be used to find the number of quarters, [tex]q[/tex]:
[tex]0.45 + 0.25q = 3.70[/tex]
