Answer:

A. t=-2h+32

Step-by-step explanation:

I'm pretty sure it's A. If the temperature starts at 32 degrees at midnight, that is going to be it's own number, not joined with a variable. In contrast, the temperature drops 2 degrees every hour, so the variable h will have a 2 with it (2h). But because it drops, the 2h will actually be negative. The equation would be written like this...

t=-2h+32, which is answer A.

I hope you understood! Good luck on your assignment and have an awesome day C:

Logan is buying three identical sandwiches and he has a coupon for$0.50 off any order. Logan only has $19.75 to spend. Which is

Serggg [28]

Answer:

The highest price of sandwiches Logan can afford is $7.08 ≈ $7.05

Option C

Step-by-step explanation:

Given as :

The amount on off coupon = $0.50

The total money which Logan can spend = $19.75

The quantity of sandwiches which Logan have to buy = 3

Let The highest price of sandwiches Logan can afford =$x + $0.50

Now, According to question

∵ The total money which Logan can spend = $19.75

And Logan have to buy 3 sandwiches

So, The total money which Logan can spend = The quantity of sandwiches which Logan have to buy × The highest price of sandwiches Logan can afford

Or, $19.75 = 3 × x

∴ x = $\frac{19.75}{3}$

I.e x = $6.58

The amount on off coupon which Logan has = $0.50

So,The highest price of sandwiches Logan can afford = x + $0.50

I.e The highest price of sandwiches Logan can afford = $6.58 + $0.50

Or, The highest price of sandwiches Logan can afford = $7.08

Hence The highest price of sandwiches Logan can afford is $7.08≈$7.05

The areas of two similar rectangles are 192 cm2 and 363 cm2. What is the similarity ratio of the two rectangles?

butalik [34]

A = ab ( the area of rectangle )
a b = 192
a b r² = 363
192 r² = 363
r = √363 / 192 = √121/64
r = 11/8
The similarity ratio of the two rectangles is 11/8.

10 - 4 (3-2y) = 8y -5

Lisa [10]

Answer:

No Solutions

Step-by-step explanation:

10 - 4(3-2y) = 8y - 5

Distribute:

10 - 12 + 8y = 8y - 5

Simplify:

-2 + 8y = 8y - 5

Same to both sides

-2 + 5 = 8y - 8y

3 = 0y

A1. 12 i.e option D

A2. 3n-7 i.e option A

A3. -6n+20 i.e option D

A4. -70 i.e option C

Step-by-step explanation:

aₙ = a₁ + (n - 1) × d

aₙ = the nᵗʰ term in the sequence

a₁ = the first term in the sequence

d = the common difference between terms

Using the above formula to solve the first part, we have :

-8 = a₁ + (2-1) × 5

-13 = a₁

a₆ = -13 + (6-1) × 5

a₆ = 12

For the second part, we have :

aₙ = -4 + (n-1)×3

aₙ = -4 + 3n -3

aₙ = 3n-7

For the third part, we have :

a₁=14 ; d=-6

aₙ = 14 + (n-1)×(-6)

aₙ = -6n + 20

For the fourth part, we have :

aₙ = 14 + (15-1)×(-6)

aₙ = -70
