Answer:
84 students (C)
Step-by-step explanation:
Since 30% of the students ate a sandwich and there is 280 students in total, then you can just do 280 x 0.30 = 84. That means the answer is C, 84 students.
Hope this helped! :)
Write an equation for: y equals three times the sum of x and two.
Answer:
y = 3x+2
Step-by-step explanation:
In a survey of sixth-grade students, 70 students, or 40% of all the students surveyed, said that they liked mustard on hot dogs. How many total students were surveyed?
I just need to know the answer! thanks :)
Answer: 210
Step-by-step explanation: 70+70+70=210 and 40% for 210 students would add up to 120% of all students surveyed. Look if there is 70 students that's been surveyed that is 40% add 40% 3 times(40%+40%+40%)=120% of all students surveyed
Answer:
28 people :)
Step-by-step explanation:
step 1: output value is 70
step 2: represent the unknown value with x
step 3: step 1 above, 70 = 100%
step 4: similarly, x = %40
step 5: this results in a pair of simple equations, 70 = 100% , x = 40%
step 6: by dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have 70/x = 100%/40%
step 7: again, the reciprocal of both sides gives x/70 = 40/70 --> x = 28
hope this helped :)

Answer:
D=102
Step-by-step explanation:
9+9=18
21x4=84
84+18=102
Answer:
D. 102 Square Unites
Step-by-step explanation:
First you do 7 x 3 to get 21
Then you do 21 x 4 to get 84
After that you do 3 x 3 to get 9
Finally you take 9 x 2 to get 18 and add that to 84 to get 102 Units

2. Only some squares are rectangles. Rectangles have 4 sides that are the same length. Therefore, only some squares have 4 sides that are the same length.
3. Only some squares are rectangles. Rectangles have 4 right angles. Therefore, only some squares have 4 right angles.
4. All squares are rectangles. Rectangles have 4 sides that are the same length. Therefore, all squares have 4 sides that are the same length.
Answer:
Not 100% sure but I believe it might be 1. I hope it helps if not let me know.
Answer:
1. All square are rectangles. Rectangles have 4 right angles. Therefore, all squares have 4 right angles.

Answer:
80 by 160 meters
Step-by-step explanation:
hi buddy
Answer:
Step-by-step explanation:
To start, lets find the length and width of the diagram shown in the problem.
Length = 8 cm
Width = 4 cm
Now, we know that every 1 cm represents 20 meters. So, we can multiply both 8 by 20, and 4 by 20. 8 * 20 = 160. 4 * 20 = 80
So, our final answer for the garden in real life are below:
Length: 160 meters
Width: 80 meters
Hope this helps, if it does please mark brainliest! If not, feel free to ask any additional questions!

Answer:1 and 2
Step-by-step explanation:
Answer:
1 and 5
Step-by-step explanation:
If and only if lines AB and CD are parallel, then 1 and 5 will be corresponding angles because they are in the same location on different lines cut by a transversal.
The cafeteria sells four kinds of sandwiches. The table shows the number of each type of sandwich sold last week. Based on the results, if the cafeteria sells 60 sandwiches today, how many of those sandwiches are likely to be ham-and-cheese sandwiches? A. 14B. 7C. 28D. Not here
Answer:
14
Step-by-step explanation:
number of sandwiches sold is equal to 300
70 sandwiches were sold so 70 out of 300 were sold
70 out of 100 simplified is 7 out of 30
60 sandwiches sold this week
60 out of 1
7/30× 60/1 = 14/1

B. 49.8 ft
C. 50 ft
D. 153.68 ft
Answer:
153.68

Answer:
459
Step-by-step explanation:
If we break up the figure inot two parts, a rectangle and triangle, we can solve for the area. The area of the rectangle is 396 because the formula for a rectangle is LxW. The area for a triangle is 1/2BxH. So the area of the triangle would be 63. Add these up together and we get 459 centimeters squared.

In the similar triangles below, what is the length of DE? with explanation
In the similar triangles below, what is the length of AC? with explanation
WILL GIVE BRAINLIEST
Answer:
Shown Below
Step-by-step explanation:
The length of DE is 12 because you would multiply by 4 for each length and AC would be 4 because you have to divide by 4
Answer:
AC=4cm and DE= 12cm
Step-by-step explanation:
So um I don't really understand the Pythagorean Theorom but what I do to solve for these kind of problems are subtract the hypotenuse from DEF which is 20cm from the leg which we know which is 16cm. So 20cm-16cm. You should get 4cm. So that goes for the last leg of the angle ABC. Then i multiplied the 2 legs from angle ABC which by the way are the lines that form the right angle at 90 degrees. the hypotenuse is the line directly across from the right angle. so I multiplied 3cm times 4 cm and I got 12 cm. So to check my work I subsituted the legs and pretended that I didn't know the hypotenuse into the Pythagorean Theorom which is a^2+b^2=c^2. A^2 and b^2 are the legs and c^2 is the hypotenuse. So when we do that we get 3^2*4^2=C^2 under the square root bar thingie. which gives us 5 for the hypotenuse of the angle ABC and subsituted the legs and the hypotenuse and did the same for the angle DEF. And so when we do that we get 12^2+16^2=C^2 which equals 20cm which we already have.
I really tried my best explaining that. I hope you do a good job.

Pls answer the 4 questions above and write an essay using the Box and Whisker plot I screenshotted. Don't forget, I'll brainliest!
1. They overlap in the 22-26 region, because of lines of both box and whisker plots are stacked on top of each other.
