Answer:
234 times
Step-by-step explanation:
<u>Number of times the number 7 appears in a hundred</u>
7 as units digit (07-17-27 ..... 97): 10 times
7 as tens digit (70-71-72..... 79): 10 times
20 times the digit 7 appears in first one hundred (0-100)
Let's calculate how many times 7 would be as units or tens in 7 hundreds
20X7 = 140 times digit 7 appears until number 699
<u>Now, from 700 to 777</u>
7 as hundreds digit (700-701-702 .... 777): 78 times
7 as tens digit (770-771-772 .... 777): 8 times
7 as units digit (707-717-727....777): 8 times
78 + 8 + 8 = 94 times the digit 7 appears in the range 700 - 777. Plus 140 times
140 + 94 = 234 times
Answer:
756
Step-by-step explanation:
The ratio of areas is the square of the scale factor.
First, we find the scale factor from the blue solid to the red solid.
scale factor = 6/4 = 3/2
The ratio of areas is the square of the scale factor:
ratio of areas = (3/2)^2 = 9/4
volume of red solid = volume of blue solid * ratio of areas
volume of red solid = 336 m^2 * 9/4 = 756 m^2
Answer: S = 756 m^2
well, we know the "sum" of both angles is 90°, notice the rectangle in the corner, so we can say that the angles are simply complementary angles, thus
Answer:
1) b 2) b
Step-by-step explanation:
1) Both expressions have (x+6). Rearrange them and you'll have one expression as (x+6) and the other as (5ab-4).
2) (4b - 7x)(a + b) factors to be 4ba + 8b - 7ax - 14x, which can be rearranged to 4ab - 7ax + 8b - 14x
Answer:
78 novels
Step-by-step explanation:
N= novels
M= month
6N = 1M
? = 13M
6N × 13M= 78NM
78NM ÷ 1M
cancel M, therefore;
the number of novels Usama needs to read in 13 months is 78.
