\Theta/\theta is "theta", not "delta" (which is \Delta/\delta)

By definition of cosine,

\cos\theta=\dfrac{19}{23}\implies\theta=\cos^{-1}\dfrac{19}{23}\approx34.3^\circ

Mr. Thompson, a retiree, looks at his check register.
sukhopar [10]

As given,

Weekly rent of Mr. Thomson is = $104.92

Part A: What is Mr. Thompson's yearly rent (using 52 weeks)?

Rent for 1 week = 104.92

Rent for 52 weeks = 104.92\times52 = $5455.84

Part B: What was the average grocery expense in this time period?

Mr. Thomson purchased groceries on 2/18 for $33.45 and on 3/5 for $28.56

Hence average grocery expense is = \frac{33.45+28.56}{2}

= $31 per week or $62.01 per month

Part C: Mr. Thompson estimates his yearly expense for groceries to be:

The monthly expense for groceries is = $62.01

So yearly expense will be = 62.01\times12 = $744.12

igomit [66]

Answer:

5/8

Step-by-step explanation:

Let x represent the size of her garden

m represent Marigolds

p represents petunias

She planted M into 2/8 of x

and also planted p into 3/8 of x

Fraction of the garden that has M and p will be:

(2/8 of x) +  (3/8 of x)

5/8 x

Hence, 5/8 of her garden has marigolds and petunias

Hey guys I need help<br> -2z-xy=x+7 solve for x<br> If you could show the steps that’ll be awesome.
Maksim231197 [3]

Answer:

x = -\frac{7 + 2z}{(y + 1)}

Step-by-step explanation:

-2z - xy = x + 7

Add 2z to both sides:

-2z + 2z - xy = x + 7 + 2z

-xy = x + 7 + 2z

Next, subtract x from both sides:

-xy - x  = x - x + 7 + 2z

- xy - x = 7 + 2z

Factor out -x from the left-hand side of the equation:

- x(y + 1) = 7 + 2z

Divide both sides by - (y + 1) to isolate x:

\frac{x(y + 1)}{- (y + 1)} = \frac{7 + 2z}{-(y + 1)}

x = -\frac{7 + 2z}{(y + 1)}
