1 answer:

4 0

The answer to this is that the height is equal to 15 feet. This is because to find the area of a triangle the equation is A=1/2bh. So what you have to do is do the opposite. Input the numbers into the equation 262.5= 1/2(35)h. Then multply 1/2 by 35 to get 17.5h. Next you divide each side by 17.5 and you get 15.

If u = 2i - j; v= -5i + 4j and w = j find 4u (v -w).

Sedaia [141]

Answer:

-40

Explanation:

Given

u = 2i - j; v= -5i + 4j and w = j

Required

4u(v-w)

4u = 4(2i) = 8i

v - w = -5i + 4j - j

v - w = -5i + 3j

Substitute

4u(v-w)

= 8i(-5i+3j)

= -40(i*i) [since i*i = 1]

= -40

Hence the required solution is -40

There is a Minecraft sale for 30% off all games. Which expression represents the total cost of Minecraft Dungeons if it cost x d

diamong [38]

Answer:

The expression x-0.3x represents the total cost of Minecraft Dungeons.

Step-by-step explanation:

Given that:

Percentage of Minecraft sale = 30% off

Cost of Minecraft Dungeons = x

Amount of discount on Minecraft Dungeons = 30% of x

Amount of discount = $\frac{30}{100}*x$

Amount of discount = 0.3x

Total cost of Minecraft Dungeons = Total cost - Discount

Total cost of Minecraft Dungeons = x - 0.3x

Hence,

The expression x-0.3x represents the total cost of Minecraft Dungeons.
