ANSWER PLSSSSSSSSSSS
mestny [16]

Answer:

B) 161.5 in²

Step-by-step explanation:

We can separate the kite figure into <em>two triangles, by cutting it vertically</em>.

So, we have two triangles with the area of <em>1/2*(6+13)*8.5</em>.

Since there is <em>two</em> of them, the equation of the total area is <em>2*1/2*(6+13)*8.5</em>.

Simplify: <em>1*19*8.5</em> (2 and 1/2 cancel out).

Multiply: <em>19*8.5</em> = 161.5 in²

A scientist mixes water (containing no salt) with a solution that contains 35% salt. She wants to obtain 140 ounces of a mixture
o-na [289]

Answer:

80 ounces water

60 ounces brine

Step-by-step explanation:

Let x be the amount of water

Let y be the amount of brine 35%

The goal is to have salt weight of 140(0.15) = 21 oz.

21 = 0.35y

y = 60 oz

x = 140 - 60 = 80 oz

There are two spinners. The first spinner has three equal sectors labeled 1, 2, and 3. The second spinner has four equal sectors
zhuklara [117]
<h3>Answer: A) 1</h3>

=========================

Explanation:

Let's label each pair of outcomes as an ordered pair (x,y)

x = first spinner outcome

y = second spinner outcome

We have these 12 different possible combos

(1,3),   (1,4),   (1,5),   (1,6)

(2,3),  (2,4),  (2,5),  (2,6)

(3,3),  (3,4),   (3,5),  (3,6)

Focus on the third column where y = 5 for each (x,y) pair. Of this column only (2,5) has x be an even number. The other results in that column have x be odd.

Basically (1,5) is the only possible outcome if we want the first spinner to lan on an even number, and the second spinner to land on 5.
