Answer: 15in^2

Step-by-step explanation:

first you need to find the area of the rectangle, so you would multiply 7 and 3, which gives you 21, (A=L•W). So now you need to find the area of the triangles, the formula for that is A= 1/2 b•h, so you get 3in for the area of the triangle, but since there are two and they are the exact same triangle you would just combine them, so the area for both triangles is 6in, so then you would need to subtract the 6 from the 21 so that you can find the area of the shape, and your final answer would be 15in(squared). hopefully you understand

Median means middle. How you solve this is by first putting the numbers in order from least to greatest:

36 41 43 45 46 48 48 51 51 52

Now that it is in order in each "level" take away the smallest and largest number until you get to the middle

36 41 43 45 46 48 48 51 51 52

41 43 45 46 48 48 51 51

43 45 46 48 48 51

45 46 48 48

46 48

Now this is a bit tricky because there isn't one number to signify the exact middle. When you have two numbers left you must take the mean of those two numbers. This means that you add the two numbers left and then divide the answer by 2:

46 + 48 = 94

94 ÷ 2 = 47

If a bird is on the ground, 7 ft away from a 10 ft tall tree, then what is the angle (to the

iren2701 [21]

Answer:

The angle is 55°

Step-by-step explanation:

To find the angle at which a bid is looking up on top of a tree that is 10feet tall if the bird is on the ground 7 feet away from the tree, we will follow the steps below:

we will use trigonometric ratio to find the angle

SOH CAH TOA

sinФ = opposite / hypotenuse

cosФ = adjacent / hypotenuse

tanФ = opposite /adjacent

from the diagram below, opposite = 10 feet and adjacent = 7 feet

the best trig.ratio to use is tan

tanФ = opposite /adjacent

tanФ = 10 /7

tan Ф =1.42857

to get the value of Ф, we will take the tan⁻¹ of both-side

tan⁻¹ tan Ф = tan⁻¹ 1.42857

Ф= tan⁻¹ 1.42857

Ф≈55°

Therefore, the angle is 55°

Otieno is k years old.He is 5 years older than kidole what will be their age fours to come

EleoNora [17]

Answer:

Otieno's age in 4 years: $k+4$

Kidole's age in 4 years: $k-1$

Step-by-step explanation:

$k$ = Otieno's age

$k-5$ = Kidole's age

Their ages will increase by 4 years when 4 years pass.

$k+4$ = Otieno's age in 4 years

$k-5+4$ = Kidole's age in 4 years

$k-1$ = Kidole's age in 4 years (after simplifying the expression)

I hope this helps!

Okay this my last one can y'all help

a. The solution is (0,2)

b. The first expression will be easier to substitute as in the first expression the variable y is already isolated on one side of the equation so we can easily put 5x+2 in place of y in equation 2.

Step-by-step explanation:

Given equations are:

$y = 5x+2\ \ \ \ Eqn1\\12.5x+2.5y = 5\ \ \ \ Eqn2$

a. Solution

Putting y = 5x+2 in equation 2

$12.5x+2.5(5x+2) = 5\\12.5x+12.5x+5 = 5\\25x +5 = 5\\25x = 5-5\\25x = 0\\x = 0$

Putting x = 0 in equation 1

$y = 5(0)+2\\= 0+2 = 2$

Hence,

The solution is (0,2)

b: Reason:

The first expression will be easier to substitute as in the first expression the variable y is already isolated on one side of the equation so we can easily put 5x+2 in place of y in equation 2.
