Mathematics
1 answer:
Westkost [7]2 years ago
8 0

Answer:

This alot but ill help you with 2 of them to learn em

Step-by-step explanation:

1) 2x^2 +5 =167

Subtract the 5 from both sides to get the equation 2x² = 162

Then divide the 2 from both sides to get x² = 81, Then square root from both sides to get x= 9

6) 2(2y +4)²=72

Divide 2 from both sides to get (2y+4)²=36

Then square root that to get 2y+4 = 6

subtract 4 from both sides to get 2y =2

Then divide both sides from 2. Y=2

Mila [183]
Answer:

We print -> 21m + 25 ≤ 500
Print so good -> 18m + 44 ≤ 500

Maximum mats from We Print : the integer part of (500-25)/21 = 22

Maximum mats from Print So Good: the integer part of (500-45)/18 = 25

#Note
We take the integer part of the division because a mat cannot be in portions

Memorial Hospital states that the minimum payment it will accept is $50 or 15% of the account,
quester [9]

Using proportions, it is found that the minimum payment the hospital will accept from the patient is of $50.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

15% of the balance of $350.00 is given by:

B = 0.15 x 350 = $52.5.

Which is a higher amount than $50, hence the minimum payment the hospital will accept from the patient is of $50.

Given that ABCD is a rhombus, what is the value of x?
choli [55]

Answer:

A. 19.5

Step-by-step explanation:

Diagonals of a rhombus intersect at right angles. Therefore the angle opposite to AD = 90°.

Thus:

90° + x + 3x + 12 = 180° (sum of ∆)

Add like terms

102 + 4x = 180

Subtract 102 from each side

4x = 180 - 102

4x = 78

Subdue both sides by 4

x = 19.5
