PLEASE HELP (only if you know what you are doing )
KiRa [710]

Answer:

1. 3     2. 22     3. 0

Step-by-step explanation:

First Box: Jada only has <u>$15</u> dollars she can spend

If she chooses to buy 6 individual songs that would cost her $3.

because each individual song cost $0.50 so (6 times 0.5= 3)

Since Jada only has $15 we need to subtract 3 from 15 to find out how much money she has left. So, 15-3=12. Jada has $12 left

An album cost $4 dollars each so Jada can only buy 3 albums with $12 because 12 divided 4 is 3.

Answer to first box: 3

Second Box:  Jada only has <u>$15</u> dollars she can spend

If she chooses to buy 1 album that would cost her $4.

because each individual song cost $4 so (4 times 1= 4)

Since Jada only has $15 we need to subtract 4 from 15 to find out how much money she has left. So, 15-4=11. Jada has $11 left

An individual song cost $0.50 dollars each so Jada can only buy 22 individual songs with $11 because 11 divided by 0.5=22.

Answer to second box: 22

Third Box: Jada only has <u>$15</u> dollars she can spend

If she chooses to buy 30 individual songs that would cost her $15.

because each individual song cost $0.50 so (30 times 0.5= 15)

Since Jada only has $15 we need to subtract 15 from 15 to find out how much money she has left. So, 15-15=0. Jada has $0 left

An album cost $4 dollars each so Jada can only buy 0 albums with $0 because 0 divided 4 is 0.

Answer to third box: 0

A standard interior staircase has steps each with a rise (height) of 21 cm and a run (horizontal depth) of 24 cm. Research sugge
Alisiya [41]

Answer:

The staircase would extends 1.20 m if the changes were made.

Step-by-step explanation:

Acording tho the statement the total heigth is 5.04 m, that is 504 cm, each steps rises 21 cm. with this information we can calculte how many steps are in the whole staircase:

Number steps= \frac{Total heigth}{each step} \\Number steps= \frac{504}{21}  = 24 steps

To calculate how much the staircase will extend, whe have to multiply the horizontal depth times the number of steps.

using the run of 24 cm that gives us a lengt of 576 cm and if the changes were made the new length will be 696 cm.

So the staircase would extend an amount of (696 - 576), that is 120 cm, or 1.20 m, if the changes were made.

Anyone can help me with this
uysha [10]

Answer:

y = - 6x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - 6, hence

y = - 6x + c ← is the partial equation

To find c substitute (- 1, 7) into the partial equation

7 = 6 + c ⇒ c = 7 - 6 = 1

y = - 6x + 1 ← equation of line

A line goes through the point (–4,–2) and has an x-intercept of –1.
Keith_Richards [23]

Answer:

y = - x - 6

Step-by-step explanation:

y = mx + b

m = - 1

y = - x + b

(- 4, - 2)

- 2 = - (-4) + b

-2 = 4 + b

b = - 6

y = - x - 6
