Answer:
6.7 seconds
Step-by-step explanation:
Juan= Paul-0.4
Paul=Terry+1.3
We can substitute Terry+1.3 for Paul since they are equal
juan=(Terry-0.4)+1.3
terry=5.8
juan=(5.8-0.4)+1.3
juan=6.7
Order is important in ratios so in this one, it says the ration from GIRLS to BOYS.
We know there are 12 girls and 9 boys so the ratio is B. 12:9
Answer:
9x + 4y < 110
Step-by-step explanation:
This inequality works because its the cost of hammers ($9) multiplied by how many hammers are bought (x) plus the cost of wrenches ($4) multiplied by how many wrenches are bought (y). The total cost has to be less than 110.
Answer:
15
Step-by-step explanation:
there are 15 sixteenths in 15/16, how you figure this out is the numerator tells you how many are in the fraction, in this case the numerator says 15, so there are 15, sixteenths in, 15/16
Answer:
1920 square inches
Step-by-step explanation:
For a rectangular prism, the lateral area can be found by ...
LA = Pl
where P is the perimeter, and l is the length.
For a square pyramid, the lateral area can be found by ...
LA = (1/2)Ph
where P is the perimeter of the base, and h is the slant height of the triangular faces.
For a figure with a square cross section of perimeter P "capped" by square pyramids on either end, the total surface area is the sum of the lateral areas of the three components:
SA = (Pl) + (1/2)Ph + (1/2)Ph
SA = P(l+h) = (4×15 in)(14 +18 in) = (60)(32) in²
SA = 1920 in²
The surface area of the solid seems to be 1920 square inches.

<em>Caveat</em>
If the figure is something other than what we have tried to describe, your mileage may vary. A diagram would be helpful.
