Answer:
Step-by-step explanation:
and 
and we are told that C is 6cm longer than A. That means that C = A + 6.
We are going to cross multiply each one of those ratios. The first one gives us
4A = 3B and the second one gives us
9B = 8C. But since C = A + 6, then
9B = 8(A + 6) and
9B = 8A + 48 and
Now we will solve the first equation above for A:
If 4A = 3B, then
and will use that as a sub for A in the second equation:
and
9B = 6B + 48 and
3B = 48 so
B = 16.
Now that we know B, we can use it to solve for A:
4A = 3(16) and
4A = 48 so
A = 12.
Then we can use that all the way back in the expression we set up for C:
C = A + 6 so
C = 12 + 6 so
C = 18
12 + 16 + 18 is the length of the string: 46cm
The answer is B. 31, since the arrow from July goes to the number 31.
Hope this helps!
Answer:
x = 39
Step-by-step explanation:
all triangles have angle measures that add up to 180°.
This means that to find what x is, you add 102 and 39, and then subtract that from 180, so
180-(102+39) = x
180-141=x
39=x
Answer:
$1.49 per pound of bananas at Smiths
Step-by-step explanation:
1. 10 pounds is $14.90
2. Find how much one pound costs by dividing 14.90 by 10
3. 14.90/10= 1.49
4. $1.49 per pound of bananas at Smiths
a)
Dimensions: 7.5m x 4.5m
Cost , x= $14.17/m^2.
The area of the rectangular room can be calculated as,
Now, the cost of carpeting the rectangular room is,
Therefore, the cost of carpeting the room with dimensions 7.5m x 4.5m is $478.24.
b)
Dimensions: 17 yd. x 12 yd.
Cost, x= $25/yd^2.
The area of the rectangular room can be calculated as,
Now, the cost of carpeting the rectangular room is,
Therefore, the cost of carpeting the room with dimensions 17 yd. x 12 yd is $5100.
