Answer:
176 words
Step-by-step explanation:
1) well we want to find the amount of words we'd be able to type in 4 minutes. so, what i did was:
<u>44 words</u> = <u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>x</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>
1 minutes = 4 minutes
2) now look at how i set up the proportion, notice how i left a variable of x for the value i didn't know.
3) we also know that 1 times 4 is 4, so it'd also make sense to also multiply the numerator by 4 too!!
4) multiplying 44 by 4 would get us our answer which is 176
im not the best at math but i this explanation helped <33
Answer:
Total surface area of the prism = 920 cm²
Step-by-step explanation:
Given prism has 2 similar triangular surfaces and 3 rectangular surfaces of different dimensions.
Area of one triangular side = 
Area of 2 similar sides = Base × Height
= 8 × 15
= 120 cm²
Area of rectangular side with dimensions 17cm × 20cm
Area of the side = 17 × 20 = 340 cm²
Area of the second rectangular side with dimensions 8cm × 20cm
Area of the side = 8 × 20 = 160 cm²
Area of third rectangular side with dimensions 20cm × 15cm
Area of the side = 20 × 15 = 300 cm²
Total surface area of the given triangular prism = 120 + 340 + 160 + 300
= 920 cm²

Step-by-step explanation:
Answer:
So, 89 Adult tickets were sold.
Step-by-step explanation:
So, we first name our variables, say, a for number of adult tickets, and c for child tickets.
Then we write our system of equations, first the total $ sale:
5.2c + 8.3a = 1087.10
Then we write the 2nd equation, the total number of tickets:
c + a = 156
Now, we can solve the system:
We do have different methods, let's to by subsitution.
make some change to the 2nd equation, to make c the subject: c = 156 - a
Now we plug that into the 1st equation:
5.2(156 - a) + 8.3a = 1087.10
811.2 - 5.2a + 8.3a = 1087.10
811.2 + 3.1a = 1087.10
3.1a = 275.9
a = 89
