There are 70 students in the school band. 40% of them are sixth graders, 20% are seventh graders, and the rest are eighth graders.
How many band members are sixth graders?
Answer:
28 band members
Step-by-step explanation:
Since 40% of the band members are sixth graders, we need to take 40% of 70 total students.
40% of 70 = 0.40*70 = 28
So 28 band members are in sixth grade

The students at Plymouth South and the students at Plymouth North both planned trips to Six Flags. The students at South rented and filled 2 vans and 11 buses with 674 students. North rented and filled 6 vans and 14 buses with 882 students. Each van and each bus carried the same number of students. Find the number of students each van and In each bus. (Write your answer as an
Answer:
Number of vans = 7 students
Number of buses = 60 students
Step-by-step explanation:
Let
Number of vans = x
Number of buses = y
2x + 11y = 674 (1)
6x + 14y = 882 (2)
Multiply (1) by 3
6x + 33y = 2,022 (3)
6x + 14y = 882 (2)
Subtract (2) from (3)
33y - 14y = 2,022 - 882
19y = 1,140
y = 1,140 / 19
= 60
y = 60 students
Substitute y = 60 into
2x + 11y = 674 (1)
2x + 11(60) = 674
2x + 660 = 674
2x = 674 - 660
2x = 14
x = 14/2
= 7
x = 7 students
Cecilia's mom ordered pizza for dinner. The pizza has two slices of pepperoni, two slices of mushroom, and two slices of anchovy. Cecilia asks her brother to bring her two slices. List all the possible combinations where the first choice is pepperoni.
Answer:
If the first slice is pepperoni, then we have left:
1 slice of pepperoni.
2 slices of mushrooms.
2 slices of anchovy.
Then the possible combinations are:
Pepperoni and pepperoni (in only one combination)
Pepperoni and mushrooms (in two combinations, because there are two slices left)
Pepperoni and anchovy (Again in two combinations, because there are two slices left)
These are the 3 possible combinations, 5 in total.
Ronnie charges his customers a flat fee of $25 to fix a computer. Then, he charges $30 for each hour he spends working on the computer. If his first job cost $175, how many hours did he spend working?
Answer:
Ronnie spent 5 hours working.
Step-by-step explanation:
From the information given, the total cost of the job is equal to the flat fee plus the result of multiplying the cost per hour for the number of hours which is:
c=25+30x, where:
c is the total cost of the job
x is the number of hours
Now, you can replace c with 175 and solve for x:
175=25+30x
175-25=30x
150=30x
x=150/30
x=5
According to this, the answer is that Ronnie spent 5 hours working.
Answer:
7.5
Step-by-step explanation:
Ronnie charges $25 plus $20 per hour. This means that he made the following depending on how many hours he spent on it:
Hours Dollars
0 25 = 25 + 0(20)=25
1 25+20 = 25 + 1(20)=45
2 25+20+20 = 25 +2 (20)=65
3 25+20+20+20 = 25 +3 (20)=85
4 25+20+20+20+20 = 25 +4 (20)=105
5 25+20+20+20+20+20 = 25 +5 (20)=125
......
n 25+n(20)=175
To find how many hours he worked for $175 we solve the equation using inverse operations:
25+n(20)=175
25-25+n(20)=175-25
n(20)=150
n= 7.5 hours

what is he slope of the line and y-intercept PLS HELP ME
Answer:
Slope: 0, y-intercept: -1
Step-by-step explanation:
If a line is completely horizontal, the slope is 0. The equation of this line is:
y = 0x - 1 = -1
The slope is 0 and the y-intercept is -1 because that is the y-coordinate this line intercepts with.

4. Emilio asks his classmates what month they were born. He finds that 15
out of 125 classmates were born in July. If there are 1,280 students in
Emilio's school, how many students can he expect to have birthdays in July
based on the experimental probability?
Ok
Answer:153
Step-by-step explanation:
From the question, we are informed that Emilio asks his classmates what month they were born and that he finds that 15 out of 125 classmates were born in July. This gives us a fraction of 15/125 = 3/25.
If there are 1,280 students in Emilio's school, the number of students that he can expect to have birthdays in July would be:
= 3/25 × 1280
= 153.6
There will be 153 students expected

Li bought his dog Spot a huge bone that is 15 inches long. Spot chews 4 inches off the bone every day. What is the new length of the bone after 3 days?
Answer:
3 inches
Step-by-step explanation:
If the dog chews off 4 inches every day, you first have to multiply the inches by the number of days, which in this case is 3 x 4, which equals 12. In 3 days, he chewed off 12 of the original 15 inches, leaving only 3 inches left.

In isosceles triangle QRS, RT is the angle bisector of ∠QRS. Mikah begins the proof by stating ∠1≅∠2. What is a valid reason for this statement? Please HELP ME!
A. Definition of Angle Bisector
B. Reflexive Property of Congruence
C. Symmetric Property of Congruence
D. Corresponding angles are congruent.
Answer:
its a
Step-by-step explanation:
Segment RT bisects ∠QRS in ΔQRS and therefore, the angles ∠1 and ∠2
formed are equal.
The valid reason for the statement ∠1 ≅ ∠2 is; A. Definition of Angle Bisector.
Reasons:
The information on the triangle ΔQRS are;
The angle bisector of ∠QRS = RT
Therefore;
∠QRT = ∠1, ∠SRT = ∠2 Given in the diagram
∠QRS = ∠QRT + ∠SRT by angle addition property
∠QRT ≅ ∠SRT by definition of angle bisector
∠1 ≅ ∠2 by definition of ∠QRT and ∠SRT
By substituting ∠QRT with ∠1 and ∠SRT with ∠2, we have;
∠1 ≅ ∠2 by definition of angle bisector
The valid reason for the statement is therefore; A. Definition of angle
bisector.

Answer:
Step-by-step explanation:
1. a). Hypotenuse² = (Leg 1)² + (Leg 2)²
h² = 10² + 24²
h = √676
h = 26
(b). Hypotenuse² = (Leg 1)² + (Leg 2)²
(25)² = (15)² + (leg 2)²
Leg 2 = √(625 - 225)
= √400
= 20
(c). Hypotenuse² = (Leg 1)² + (Leg 2)²
h² = 4² + 6²
h = √(16 + 36)
h = √52
h = 2√13
(d). Hypotenuse² = (Leg 1)² + (Leg 2)²
(14)² = (Leg 1)² + 7²
Leg 1 = √(196 - 49)
= √147
= 7√3
2). Hypotenuse² = (Leg 1)² + (Leg 2)²
Leg 1 = leg 2 = 7 units [Since, triangle is an isosceles triangle]
h² = 7² + 7²
h = √98
h = 7√2
Option (1) is the correct option.
3). Hypotenuse² = (Leg 1)² + (Leg 2)²
(26)² = (Leg 1)² + (10)²
Leg 1 = √(676 - 100) = 24
Area of a right triangle = [tex]\frac{1}{2}(\text{Leg 1})(\text{Leg 2})[/tex]
= [tex]\frac{1}{2}(24)(10)[/tex]
= 120 square units
Option (3) is the correct option.
