8 0

Answer:

Step-by-step explanation:

The absolute value function always returns a positive value, that is

| - a | = | a | = a

Given

8 - | 2g - 5 | ← substitute g = - 3.5 into the expression

= 8 - | - 7 - 5 |

= 8 - | - 12 |

= 8 - 12

= - 4 → D

Here BD is perpendicular bisector

UB=BV=74

$\\ \tt\hookrightarrow UV=74+74=148$

Apply Pythagorean theorem

$\\ \tt\hookrightarrow BD^2=UD^2-UB^2=UD^2-VD^2$

UD=VD=78=TD

$\\ \tt\hookrightarrow TC^2=TD^2-CD^2$

$\\ \tt\hookrightarrow TC^2=78^2-30^2$

$\\ \tt\hookrightarrow TC^2=6084-900=5184$

$\\ \tt\hookrightarrow TC=72$

Marco is making a kite, using sticks for its diagonals. One stick is 2 feet long and the other is 3 feet long. How much material

Marat540 [252]

Answer:

Marco will need $3\ ft^{2}$ of material to make the kite

Step-by-step explanation:

we know that

To know how much material Marco will need to make the kite, the area must be calculated.

Remember that the area of the kite is equal to

$A=\frac{1}{2}[d1*d2]$

where

d1 and d2 are the diagonals of the kite

we have

$d1=2\ ft$

$d2=3\ ft$

substitute

$A=\frac{1}{2}[2*3]=3\ ft^{2}$

How can you check your answer in unit rates?

muminat

Answer:

<h3>⭐In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1. For example, if 50km is covered in 5.5 hours, the unit rate will be 50km/5.5 hours = 9.09 km/hour.</h3>
