A grocer sells 30 loaves of bread a day. The cost is $2.50 per loaf. The grocer estimates that for each $0.50 increase in cost,

Viktor [21]

Answer:

none of the above

Step-by-step explanation:

The grocer's revenue will be the product of the number of loaves sold (30-2x) and their price (2.50+0.50x).

Revenue will be positive for values of x between those that make these factors be zero. The number of loaves sold will be zero when ...

... 30 -2x = 0

... 15 -x = 0 . . . . . divide by 2

... x = 15 . . . . . . . add x

The price of each loaf will be zero when ...

... 2.50 +0.50x = 0

... 5 + x = 0 . . . . . . . multiply by 2

... x = -5 . . . . . . . . . . subtract 5

Revenue will be positive for any number of increases greater than -5 and less than 15.

_____

D is the best of the offered choices, but it is incorrect in detail. -5 is a number less than 15, but will give zero revenue.

Kurt earns $7 per hour for doing chores. his goal is to make at least $35 each week

Yuri [45]

Answer:

Step-by-step explanation:

This is what i get what i understand from your question .

Kurt earns $7 per hour for doing chores. his goal is to make at least $35 each week

So ,

$7 =per hr

X= unknown hrs

$35= goal

7 x =35

Divide both sides by 7 to get x alone representing hrs.

X= 35/7

X= 5

So 5 hrs per week to make 35 a week.

5×7=35

35=35

Using complete square to slove for x in the equation (x+7) (x-9)=25

Brrunno [24]

Answer:

$x_1=1+\sqrt{89}\\\\x_2=1-\sqrt{89}$

Step-by-step explanation:

Apply Distributive property:

$(x+7)(x-9)=25\\\\x^2-9x+7x-63=25$

Add like terms and then add 63 to both sides of the equation:

$x^2-2x-63=25\\\\x^2-2x-63+63=25+63\\\\x^2-2x=88$

Pick the coefficient of the x term, divide it by 2 and square it:

$(\frac{2}{2})^2=1$

Add it to both sides of the equation:

$x^2-2x+1=88+1$

Rewriting the left side as a squared binomial, we get:

$(x-1)^2=89$

Apply square root to both sides:

$\sqrt{(x-1)^2}=\±\sqrt{89}\\\\x-1=\±\sqrt{89}$

And finally we need to add 1 to both sides of the equation. Then we get:

$x-1+1=\±\sqrt{89}+1\\\\x=\±\sqrt{89}+1\\\\\\x_1=1+\sqrt{89}\\\\x_2=1-\sqrt{89}$

Anit [1.1K]

Answer:

2,752

Step-by-step explanation:

English Translation

A man was going to Bahia with his seven sisters. Each sister carried seven boxes, each box had seven cats, each cat had seven puppies. How many were going to Bahia?

Solution

1 man was going to Bahia

With his 7 sisters.

Total nunber of humans = 1 + 7 = 8 humans

Each of the 7 sisters carried 7 boxes.

Each of the 49 boxes had 7 cats

Total number of cats = 7 × 7 × 7 = 343 cats

Each of the 343 cats had 7 puppies

Total number of puppies = 7 × 343 = 2401 puppies.

Total number of living things going to Bahia

8 humans + 343 cats + 2401 puppies

= 2,752

Hope this Helps!!!
