A play station costs $500, but you want to only pay $450. How much discount in percents do you want?

Alexus [3.1K]

Answer:

You only want a 10% discount...

500 - 450 = 50

50/500 = 1/10 = .1 = 10%

Sarah hopes to be 5 feet tall by her next birthday. Right now, she is 148 centimeters tall. About how many more centimeters does

Alla [95]

Answer:

4.4 cm

Step-by-step explanation:

To solve this problem, we have to remind the conversion factor between feet and cm. We know that:

1 foot = 12 inches

1 inches = 2.54 cm

So,

$1 ft = 12 \cdot 2.54 =30.48 cm$

In this problem, Sarah's height right now is

h = 148 cm

She wants to be 5 feet tall by her next birthday: it means that her height should be

$h'=5 ft \cdot 30.48 =152.4 cm$

Therefore, she needs to grow by:

$h'-h=152.4-148=4.4 cm$

So, she needs to grow 4.4 cm more in order to be 5 feet tall.

Write an explicit formula for an arithmetic sequence whose common difference is -4.5

makvit [3.9K]

If the difference is always -4.5, then it is always -4.5 times something, so that it changes -4.5 ever 1 number. This means that our equation is y=-4.5x. From there, we can add any constant, as it will not change the difference. I will leave that up to you to pick, so the equation is y=-4.5x+C, where C is any real number.

Hope this helps!

Charley's grade in the three quarters are 85, 88, and 92. If she targets to have an average

topjm [15]

Step-by-step explanation:

We can set up an average equation in the form, where x is the last score in the fourth quarter:

$\frac{85 + 88 + 92 + x}{4} = 90$

$85 + 88+92 + x =360\\\\x = 95$

She needs at least a 95 on the last quarter to average 90 in all four quarters.
