Answer:
a)x=5 b)x=4
Step-by-step explanation:
a)9.5×2=19
3x+4=19
19-4=15
15÷3=5
x=5
b)5×3=15
7+2x=15
15-7=8
8÷2=4
x=4
hope this helps
the formula for this questions would be pie multiplyed by d
so to solve this problem you would 3.14* 120 which equals 376.8
what you need to do to find six laps is multiply 376.8 with 6
which gives you 2260.8
answer- 2260.8
Answer:
72
Step-by-step explanation:
Let
Carl grades = x = 62, 78, 59, 89
Number of grades, N = 4
Mean of Carl's grade = sum of x / number of grades,N
= (62 + 78 + 59 + 89) / 4
= 288/4
= 72
Therefore, mean of Carl's grade = 72
Answer:
false
Step-by-step explanation:
the relationship between lengths/dimensions and areas is that areas are created by multiplying 2 dimensions.
when you quadruple (×4) the dimensions, then the areas are growing with the square of the factor (×4×4 = ×16), because the factor goes twice into the multiplication : one time for every dimension involved.
so, quadrupling the dimensions would multiply the areas by 16.
Answer:
58
Step-by-step explanation:
For every triangle, all angles add up to 180. So you have to subtract 64 from 180 which gives you 116. You then take that number and divide it by two because there are two base angles, which gives you 58. The answer is 58.
