The 3rd question out of 13 is tangent39= opposite/adjacent

So tan39=x/190
Multiple 190 by both sides

190tan39=x

The value of a rectangle is 128 cubic yards. The base of the prism has an area of 8 square yards.

san4es73 [151]

Answer:

<h2>16 yards</h2>

Step-by-step explanation:

Given,

Volume of the rectangular prism = 128 cubic yards

Base area of the prism = 8 square yards

Let,

Height of the prism be = h

As we know, 

Base area × height = Volume of the given prism

Therefore, 

By the problem,

=> 8 sq. yd × h = 128 cu. yd

=> 8h = 128

(On dividing 8 from both sides)

$= > \frac{8h}{8} = \frac{128}{8}$

(On Simplification)

=> h = 16

Hence, the height (h) of the prism is 16 yards (Ans)

(PLEASEEE HELP ASAP!!) The Sugar Sweet Company will choose from two companies to transport Its sugar to market. The first compan

Answer:

Q1:14 Q2:8903.5

Step-by-step explanation:

I find that using equations to solve problems makes it a lot easier.

The first company's equation would be y=5743+225.75x because 5743 is the set fee and 225.75 is for each ton of sugar. The second company would be y=7500+100.25x for the same reasons.

So we need to find a value of x that works for each company and a value of y that is the same for the cost.

Now we combine them.

Solve for x:

5743+225.75x=7500+100.25x

-5743 -5743

225.75x= 1757+100.25x

-100.25x -100.25x

125.50x=1757

/125.5 /125.5

x=14

Therefore, for Q1, the answer is 14.

Now we solve for y by substituting x for 14.

5743+225.75(14)

5743+3160.5

8903.5

We can also check this with the other equation

7500+100.25(14)

7500+1403.5

8903.5

So therefore, the answer to Q2 would be 8903.5.

An = an-1 + What number belongs in the blank space in the recursive formula?

-Dominant- [34]

Answer: D) 8

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

The number outside the (n-1) term, which is 8, is the common difference. It tells us how much to increment by each time. In this case, the next term is found by adding 8 onto the previous term. That's exactly what $a_n = (a_{n-1}) + 8$ is saying.
