Answer:
140.4ft^2
Step-by-step explanation:
since all four sides are equilateral triangles, you only need to find one triangle and multiply by 4.
area of triangle = 0.5×base×height = 0.5×7.8ft×9ft =35.1ft^2
surface area of pyramid= 35.2ft^2 × 4 = 140.4ft^2

A: The maximum is greater for Group B than for Group A.
B: The data for Group B is more spread out than the data for Group A.
C: The maximum is greater for Group A than for Group B.
D:The data for Group A is more spread out than the data for Group B.

Step-by-step explanation:
I think its a because the IQR is the third quartile minus the first quartile (third-first=IQR)(the first is the middle number between the minimum and median and the third quartile is the middle number between the median and the maximum)so anyway it just makes sense that the answer would be B

2 in²
Step-by-step explanation:
1 in²/25 mi² = x in ²/ 50 mi²
25 * x = 50
x= 50/25
x= 2
therefore, The area of the wildlife refuge is [2in²] square inches on the map.
1in/25mi= x/50
Since 25 is half of 50 we can assume that 1 is half of x.
Knowing this we can add 1+1 (Easy math here!) to get 2

Because of corresponding angles, the measure of the angle next to Angle 1 is 50 degrees, due to corresponding angles. Because of the sum of angles in a triangle is 180 degrees, measure of Angle 1 is 60 degrees. The linear pair of angle 2 is angle 1, which is 60 degrees. Because of linear pair, measure of angle 2 is 120 degrees.

Ociel has designed a square mural that measures 10 feet on each side. Bill has also designed a square mural, but his measures y feet shorter on each side. How much smaller than Ociel's mural is Bill's mural? Explain.
Answers
Answer:
10²- y²
Step-by-step explanation:
Since the mural is 10 feet on one side we can make the size of Ociel's mural just 10². Of course, the same would go for Bill's mural except we square however long one of his sides is. So just subtract Bill's (y²) from Ociel's (10²).

julia and kelsey are both babysitters. julia charges a flat fee of $30 plus $5 per hour. and kelsey charges a flat fee of $10 plus $15 per hour. which system of equations represents the information given? let z represent the number of hours spent babysitting. let y represent the money earned. (answer choices are in the picture)
Answers
Answer:
I think it's the 2nd choice. Hopefully I got this correct :)
Step-by-step explanation:
I think you wrote that z will represent the number of hours spent babysitting but I think you meant x.
It's the 2nd choice because $30 is the flat rate for Julia and $10 is the flat rate for Kelsey. Julia has a rate of $5 per hour so that will be the number with the x. And Kelsey has a rate of $15 per hour so that will be the number with the x.
Julia: y = 5x + 30
Kelsey: y = 15x + 10.

-6(q+1)-4q = -10q-6, so that can't be the answer
2(q-3) = 2q - 6. But the 2q isn't negative, so therefore, this isn't the answer either
Therefore, the answer is C: None of the above
