D. 68
I don’t remember what formula this is called but the formula says that all angles in a triangle should add up to 180, so 75+37= 112, 180-112= 68

Answer:

a. 68

Step-by-step explanation:

You just have to subtract these two numbers from 180 because adding all the angles of a triangle the resulta is 180. Subtracting those numbers from 180 will give you the result.

If f(x)=×^2+7x-5 and you divide by x-2, What is the quotient and remainder?

katrin [286]

Answer:

The quotient is : x+9

The remainder is : 13

Step-by-step explanation:

The question requires you to perform the long division method;

This will be;

$x-2\sqrt{x^2+7x-5}$

start with the x term in x-2 and the first term in the function, x², to get x then multiply the x with x-2 to get x²-2x and perform the operation below;

x-2√x²+7x-5 -----------to first get x and then multiply x*[x-2]⇒x²-2x

- x²-2x+0 ------------perform subtraction of like terms

---------------------

9x-5 ----now divide this answer by x-2 ,starting with x and 9x

----------------------This will give , 9 then multiply 9 by x-2 to get 9x-18 and perform the subtraction operation as;

9x-5

- 9x-18

------------------------

So the answer will be; x+9 remainder 13

Nooha purchased a tv for $9000 and sold it at a profit of 8% find selling price

miskamm [114]

Answer:

720

Step-by-step explanation:

because 8% of 9000$ is 720$.

another way.

Step 1: Our output value is 9000.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$9000=100$.

Step 4: Similarly, $x=.8%$.

Step 5: This results in a pair of simple equations:

$9000=100%(1)$.

$x=.8%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

Step 7: Again, the reciprocal of both sides gives

Therefore, 8%of $9000$ is $720

An assembly line with 10 tasks needs be designed. The total time for all tasks is 16 minutes. If you need to produce 30 units/ho

Sindrei [870]

Answer: 8 minimum work stations is what would be needed.

Step-by-step explanation:

The cycle time is computed as the operating time daily divided by the scheduled output.

It is important to note that the daily capacity of the operation layout is the operating time divided by the cycle time.

Therefore,

If you need to produce 30units/hour.

The average cycle time is as follow:

The average cycle time is the average time between the completions of units.

60/30= 2 average cycle time

=16/2

8 work stations is the minimum number that would be needed.

It is important to know that in an assembly line balancing, the minimum number of work station is the ratio of the sum of all tasks time to the cycle time.

The diagram shows a prism.

telo118 [61]

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 = $\frac{1}{2}(\text{Base})(\text{Height})$

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
