Suppose you know that ∠s and ∠y are complementary, and that m∠s = 4(m∠y) − 110°. find m∠y. solution

1 answer:

6 0

∠s + ∠y are complementary
∴ ∠s + ∠y = 90°

∠s = 4(∠y ) -100

s + y = 90
4y - 100 + y = 90
5y = 90 + 100
5y = 190
y = 38

Ans: y = 38°

Sonja uses 8 of the 12 eggs in her dozen eggs to make a breakfast casserole. Olga uses 5/6 of a dozen eggs to make scrambled egg

GREYUIT [131]

Answer:

Olga will use 10 eggs, while Sonja will use 8, thus Olga will use more eggs.

Step-by-step explanation:

Given that Sonja uses 8 of the 12 eggs in her dozen eggs to make a breakfast casserole, while Olga uses 5/6 of a dozen eggs to make scrambled eggs, the following calculations must be performed to determine who uses more eggs:

Sonja = 8/12 = 0.666 x 12 = 8

Olga = 5/6 = 0.83333 x 12 = 10

Therefore, Olga will use 10 eggs, while Sonja will use 8, thus Olga will use more eggs.

H(y)=-3y^2+5 p(y)=y^3-7y Find (h-p)(y)

gladu [14]

$(h-p))(y) = -y^3-3y^2+7y+5$

Step-by-step explanation:

Given

$h(y) = -3y^2+5\\p(y) = y^3-7y$

We have to find the difference of two functions given

So,

$(h-p)(y) = h(y) - p(y)\\= (-3y^2+5)-(y^3-7y)\\=-3y^2+5-y^3+7y\\=-y^3-3y^2+7y+5$

Hence,

$(h-p))(y) = -y^3-3y^2+7y+5$

Multiple Roots

Step-by-step explanation:

Step 1: Define

x² = 625

Step 2: Solve for x

Square root both sides: x = ±25

Step 3: Check

Plug in x into the original equation to verify it's a solution.

x = -25

Substitute in x: (-25)² = 625
Exponents: 625 = 625

Here we see that 625 does indeed equal 625.

∴ x = -25 is a solution to the equation.

x = 25

Substitute in x: 25² = 625
Exponents: 625 = 625

Here we see that 625 does indeed equal 625.

∴ x = 25 is a solution to the equation.
