Answer:

Step-by-step explanation:

You can first find out whats in the parenthesis, then you multiply it by the number next to the parenthesis like this: 6+ (3 * 11) - 5^2. Now we get

6 + 33 - 5 ^ 2 [aka 5 * 5 aka 25] Now we have 6 + 33 = 39, so 39 - 25 = 14.

6 + 3 (13-2) - 5 squared

(13-2) = 11×3= 33

33+6= 39

39-5 squared = (5×5) = 25

so 39-25=14

14 is you answer

When Alice went to the print shop, she was confronted with many choices of sizes: 7-inch by 9-inch, 8-inch by 10-inch, and 12-in

Alex

Answer:

12-inch by 16-inch- it's the largest available and can be reduced to scale for smaller photos.

Step-by-step explanation:

-Given the dimensions 7-inch by 9-inch, 8-inch by 10-inch, and 12-inch by 16-inch:

#If Alice buys 7-inch by 9-inch and the photo turn's out to be a 8-inch by 10-inch or 12-inch by 16-inch then part of her photo will be cut off.

Hence, Don't buy.

#If Alice buys 8-inch by 10-inch and the photo turn's out to be a 12-inch by 16-inch then part of her photo will be cut off. However, if the photo is a 7-inch by 9-inch then it will fit.

Hence, don't buy.

#If Alice buys a 12-inch by 16-inch and the photo turns out to be smaller than expected the she can always print it out and trim or reduce the to scale excessive print paper to the desire dimensions.

Hence, buy the 12-inch by 16-inch since it's the largest available and can be reduced to scale for smaller photos.

If I Had A Hammer Hardware has sales of $5000 in its first month. Suppose sales were to increase by 4% every month. In how many

mixer [17]

After 14 months after the first month would the sales reach $9000

For given question,

A Hammer Hardware has sales of $5000 in its first month.

The sales were to increase by 4% every month.

We need to find the number of months after the first month would the sales reach $9000

Let the exponential function for sales is,

f(n)= a (1 + r)^{n}

where, n is the number of months

a is the sales of the first month

r is the rate of increment

So, a = $5000, r = 0.04, f(n) = $9000

Substitute values in above equation.

⇒ 9000 = 5000 × (1 + 0.04)^{n}

Solve above equation for n.

⇒ 1.8 = (1.04)^n

⇒ n = $log_{1.04}^{(1.8)}$

⇒ n = 14.9

⇒ n ≈ 15

Therefore, after 14 months after the first month would the sales reach $9000

A. The ratio between the lengths of two

Amiraneli [1.4K]

Answer:

14 feet

Step-by-step explanation:

Let the shorter piece have length x.

Since the ratio is 2:3 and the longer piece is 21 feet long, we can write that as 2:3 = x:21.

Writing it as fractions, we get 2/3 = x/21 —(multiply by 21)—> x = 21*2/3 = 7*2 = 14 feet.

Thus, the shorter piece is 14 feet.

I hope this helps! :)

Steven is moving to another city next weekend and wants to rent a moving truck. The rental rates for two companies in his area a

ASHA 777 [7]

Answer:

Company (1) charges $1.12 per mile and company (2) charges $0.85 per mile

Company (2) is $7.4 cheaper.

Step-by-step explanation:

From the tables given in the picture,

Let the equation representing the rental 'y' and distance traveled 'x' is represented by,

y = mx + b

For company (1),

Here m = per mile rental charges = Slope of the graph

b = Initial charges

Since slope of the line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

m = $\frac{y_2-y_1}{x_2-x_1}$

Therefore, slope of the line passing through (30, 53.55) and (60, 87.15) will be,

m = $\frac{87.15-53.55}{60-30}$ = $1.12 per mile

So the equation will be,

y = 1.12x + b

Since this line passes through (30, 53.55),

53.55 = 1.12(30) + b

b = 53.55 - 33.6

b = 19.95

So the expression representing charges for the company (1) will be,

y = 1.12x + 19.95

For company (2),

Per mile charges = slope of the line

m = $\frac{78-56.75}{50-25}$

m = $0.85 per mile

Equation for the charges will be,

y = 0.85x + b

Since this line passes through (25, 56.75),

56.75 = 0.85(25) + b

b = 56.75 - 21.25

b = 35.5

Therefore, equation representing total charges for company (2) will be,

y = 0.85x + 35.5

By comparing per mile charges,

Company (1) charges $1.12 per mile and company (2) charges $0.85 per mile

Steven plans to drive 85 km in rental truck.

Charges for company (1),

y = 1.12x + 19.95

y = 1.12(85) + 19.95

y = $115.15

Charges for company (2),

y = 0.85x + 35.5

y = 0.85(85) + 35.5

y = $107.75

Difference in charges of both the companies = 115.15 - 107.75 = $7.4

Therefore, company (2) is $7.4 cheaper.
