Answer:

I put it in step by step because it is easier. (ans)

Step-by-step explanation:

Angle 1: It is a right angle so it is (90 degrees).

Angle 2: A triangle has 180 degrees. 90 plus 22 is 112 and 180 minus 112 is (68 degrees).

Angle 3: Since angles 2 and 3 are supplementary (2 angles summed to 180 degrees), 180 minus 68 is (112 degrees).

Angle 4: This is the same angle as 3 so it is also (112 degrees).

Angle 5: This is supplementary to 3 and 4 so 180 minus 112 is (68 degrees).

Angle 6: There are markings meaning the side lengths are the same. The angle opposite of its lengths are corrosponding. So meaning unnamed angle and 6 are the same. So 180-68 is 112 and 112/2 is (56 degrees).

Angle 7: We already know the unnamed angle is 56 degrees as it is the same as angle 6. Unnamed angle and 7 are supplementary. 180 minus 56 is (124 degrees).

Angle 8: It is the same as angle 7 (124 degrees).

Answer: $0.44

Step-by-step explanation: a) (3 * 0.75) + ((1/4)*2.76) = 2.25 + 0.69 = 2.94

Pays with $5 - $2.94 = $2.06 Change

((1/2) * 3.24) = $1.62

Money left = 2.06 - 1.62 => $0.44

solve the equation 5 over 4 minus 1 over x minus 2 equals -4 over 4x minus. use complete sentences to explain how you solved the

ehidna [41]

Let's translate your words into numbers and fractions. So it's
5/4 - 1/x - 2 = -4/-4.
Let's Simplify it first by eliminating -4/-4, the answer will be 1 since negative divided by negative is positive and 4 divided by 4 is 1.

5/4 - 1/x - 2 = 1

Then Get the GCF of the equation which is 4x.
Then divide the whole equation by 4x and it would be,

<span><u>5/4 - 1/x - 2 = 1
</u></span> 4x

Then it will look like this, 5x-8x-4 = 4x
Then transpose, 5x - 8x - 4x = 4
Simplify by deducting the left side. -7x = 4
Then divide both sides by -7.
Then the final answer would be x = -4/7

Answer:

At the 3rd day 160 students caught flu.

Step-by-step explanation:

Consider the provided model P = − t ² + 13t + 130 where 1 ≤ t ≤ 6

The total number of students is represents by P.

We need to find the day that 160 students had the flu.

Substitute the value of P=160 in above formula.

$160 = -t^2 + 13t + 130$
