Answer:

We need 8 cement spheres. With each on sphere being made, we use 2.5ft of cement.

To figure out this problem, all we need to do is 8 x 2.5

Write the numerical expression for the product of 8 and the sum of 9 and 11.3. Then evaluate it.

Klio2033 [76]

Answer:

162.4

Step-by-step explanation:

To write the numerical expression for the product of 8 and the sum of 9 and 11.3 we need to follow these steps:

Sum of 9 and 11.3 is given as follows:

$(9+11.3)$

Now the product of 8 and the sum of 9 and 11.3 is:

$8(9+11.3)$

So the required expression is:

$8(9+11.3)$

Solving the above expression we get:

$8(9+11.3)=8(20.3)=8 \times 20.3=162.4$

3A: Determine the value of angle 1 and provide a reason why. *

Otrada [13]

The answer is 45°

By determining the angles of triangle ACB (A=30°, B=45°, C=105° (total of 180°)) and knowing that angle 1 correlates to angle 4 ((1)°=(4)°), we can find angle 1, which is 45°, equal to angle 4.

Multiply (6 - 5)².<br> OA) 11+ 60i<br> B) 36 +25i<br> OC) 11-60i<br> OD) 36-25i

MA_775_DIABLO [31]

Answer:

$\textsf{C)} \quad 11-60i$

Step-by-step explanation:

$\textsf{Multiply }\: (6-5i)^2$

$\implies (6-5i)(6-5i)$

$\implies 6(6-5i)-5i(6-5i)$

$\implies 36-30i-30i+25i^2$

$\implies 36-60i+25i^2$

$\textsf{Remember that }i^2=-1:$

$\implies 36-60i+25(-1)$

$\implies 36-60i-25$

$\implies 36-25-60i$

$\implies 11-60i$
