Answer:
all students in the club
Step-by-step explanation:
Answer:
C. All students in each grade
Step-by-step explanation:
Answer choices A and B are the worst choices to represent all students in the school. D can also be crossed off because students in the social studies club would most likely have a biased answer. Surveying all students in each grade produces the most random, unbiased results, so C would be the best answer.
Hope this helps!
Pls help asap;.;.;.;.;.;
Answer:
Count the distance across from point A to point B
To make this easier, bring point B to the same height level as point A then count the units over.
If we bring point B two units up, we can see that the distance between point B and A is 6 units apart.
The original price of a truck is $30,100. There is a sale going on that offers 35% off. What is the total selling price of the truck?
A. $36,120
B. $31,605
C. $19,565
D. $10,535
Answer:
19,565
Step-by-step explanation:
35% of 30,100=10,535
subtract that by 30100
30100-10535=19565
quick mafss
Answer:
c
Step-by-step explanation:
original price=30100
35% off = 30100 * 35% = 30100 * 0.35 = 10535
10535 is the savings, so substract this from the original price to get new price
30100-10535= [19565]

Answer: Find the area of the trapezoid!
= 1012 meters
Step-by-step explanation:
Surface Area = 2×(12×13 + 12×14 + 13×14)
Hopefully this helps you!
-Keira
Answer:
169 mi²
Step-by-step explanation:
To find the area of a trapezoid, use this formula:
[tex]A=\frac{a+b}{2} h[/tex]
"a" and "b" represent the two bases (12 mi and 14 mi), and the "h" stands for height (13 mi). Insert these values into the equation.
[tex]A=\frac{12+14}{2} 13[/tex]
[tex]A=\frac{26}{2} 13[/tex]
[tex]A=13 * 13\\= 169[/tex]
Therefore, A = 169. :)
The mass of a basket containing 3 balls was 3.64 kilograms. The mass of the same basket and 5 balls is 5.26 kilograms. Find the mass of the empty basket in kilograms.
a. the mass of a empty basket is ___
b. explain your answer (in short)
please help
Answer:
mass of empty basket: 1.21 kg
Explanation:
the mass of basket is constant. Let the mass of basket be "b" and mass of each balls be "m"
Make equations:
b + 3(m) = 3.64 ___ equation 1b + 5(m) = 5.26 ___ equation 2solve them simultaneously,
3.64 - 3(m) = 5.26 - 5(m)-3(m) + 5(m) = 5.26 - 3.642(m) = 1.62m = 0.81 kgmass of basket,
b = 3.64 - 3(m)3.64 - 3(0.81 )1.21 kgNow
x+3y=3.64=>x=3.64-3y--(1)x+5y=5.26=>x=5.26-5ySo
3.64-3y=5.26-5y-3y+5y=5.26-3.642y=1.62y=0.81kgSo
x=3.64-3(0.81)=3.64-2.43=1.21kgcan you help me please

You are assigned 32 math exercises for homework. You complete 87.5% of these before dinner. How many do you have left to do after dinner?
How Many problems Are left
Answer:
4 problems
Step-by-step explanation:
(I'm going to type a lot, but it isn't at all hard when you really understand and get the hang of it) If you are assigned 32 math exercises for homework and you complete 87.5% of them, this means that the problem is not asking for 87.5 % of 32, but what is left after you finish 87.5%, which means we should subtract 87.5 from 100. 100-87.5=12.5. 12.5% now represents the percent of the 32 original questions we have left to do after dinner. So, now we need to create a proportion. 12.5% means 12.5% out of 100%, with the 100% meaning 32, because that is the total amount of questions we have. so, this means we have [tex]\frac{12.5}{100}[/tex]. To use this to solve our problem, we have to act as if the 32 also represents 100%. So, we have to multiply this fraction ([tex]\frac{12.5}{100}[/tex]) by [tex]\frac{x}{32}[/tex] so that the 12.5% out of 100 lets us see how many problems 12.5% out of 100% would represents the remaining questions out of 32. so, we would solve for x (x representing the questions left to do after dinner.) So, we would form this equation and solve for x. -->[tex]\frac{12.5}{100} =\frac{x}{32}[/tex]. Now, we would cross multiply, then divide. So we would first multiply 12.5 times 32. This would give us 400. Then, we divide 400 by the 100, which gives us 4, which means that we have 4 problems left to do after dinner.
What percentage of the mile times range from 7.25 to 9.375?
Answer:
0.6796875
Step-by-step explanation:
1. We assume, that the number 9.375 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 9.375 is 100%, so we can write it down as 9.375=100%.
4. We know, that x is 7.25% of the output value, so we can write it down as x=7.25%.
5. Now we have two simple equations:
1) 9.375=100%
2) x=7.25%
where the sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
9.375/x=100%/7.25%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 7.25% of 9.375
9.375/x=100/7.25
(9.375/x)*x=(100/7.25)*x - we multiply both sides of the equation by x
9.375=13.793103448276*x - we divide both sides of the equation by (13.793103448276) to get x
9.375/13.793103448276=x
0.6796875=x
x=0.6796875
now we have:
7.25% of 9.375=0.6796875
The percentage of the mile 7.25% of 9.375 =0.6796875.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
We have to find percentage of the mile times range from 7.25 to 9.375.
let 9.375 represents 100% and x represents 7.25%.
Then, using proportion we can write
9.375/x=100%/7.25%
9.375/x=100/7.25
9.375 (7.25)= 100x
100x = 67.96875
x= 0.6796875
Thus, 7.25% of 9.375 =0.6796875

Calculate the snow load for the low-slop (flat) roof. For this structure, we will use the following coefficients. Cs = 1.0 Ce = 1.0 Ct = 1.0 Is = 1.1 Pg = 25
Answer:
The width of member is as follows:
b = 3 ft
b = 3 × 12 in.
b= 36 in.
The depth of member is as follows:
d = 8 ft
d = 8 × 12 in.
d=96 in.
Since the structure used is Douglas fir-Larch lumber of size 3 × 8 size. Hence, tensile strength, f =1000 psi
Calculate the net area of the member as follows:
A = (b - ∅) × d
A= (36 - 7/8) × 96
[tex]A = 3372in^{2}[/tex]
Calculate the maximum axial tensile load by ASD method as follows:
P = f × A
P = 1000 x 3372
P = 3372000 lbs
P = 3372 kips

Answer:
x ≤ 40
Step-by-step explanation:
Given:
[tex]\displaystyle \large{\dfrac{x}{-8} \geq -5}[/tex]
Multiply both sides by -8 to get clear out the denominator:
[tex]\displaystyle \large{\dfrac{x}{-8}\cdot (-8) \geq -5\cdot (-8)}\\\displaystyle \large{x\geq 40}[/tex]
Because the LHS (Left-Handed Side) expression is in negative, make sure not to forget to swap the sign from ≥ to ≤
Hence, the solution is x ≤ 40
