Interest earned: $294<br> Principal: $600<br> Interest rate: 7%<br> Time:

ICE Princess25 [194]

Answer: 7 years

Step-by-step explanation:

Given the formula for simple interest as

Principal × Rate × Time

To find Time is therefore 100 × Interest/ Principal x Rate

From the above question,

Principal is given as 600;

Interest is 294 and

Rate is 7%

Slot the values into the formula:

100 × 294/ 600 x 7

= 29400/4200

Therefore, Time (T) is 7 years

I hope this is clear, please mark as brainliest

A rock falls off a balcony. It’s height(in feet)is given by the formula f(x)= -16t^2+12.5t+150, where t is measured in seconds.

ELEN [110]

Answer: $3.47\ seconds$

Step-by-step explanation:

Given the following function:

$f(x)= -16t^2+12.5t+150$

You need to follow these steps in order to solve the exercise:

1. Substitute $f(x)=0$ :

$0= -16t^2+12.5t+150$

2. Now you need to apply the Quadratic formula. This is:

$x=t=\frac{-b\±\sqrt{b^2-4ac} }{2a}$

In this case, you can identify that:

$a=-16\\b=12.5\\c=150$

Then, you can substitute these values into the formula:

$t=\frac{-12.5\±\sqrt{(12.5)^2-4(-16)(150)}}{2(-16)}$

3. Evaluating, you get:

$t_1=3.47\\\\t_2=-2.69$

4. You must choose the positive value. Then:

$t=3.47\ seconds$

For each container of tea, McKenzie uses 16 tea bags and 3 cups of sugar. If McKenzie uses 64 tea bags, how many cups of sugar w

cestrela7 [59]

So tis is a ratio 16 is to 3 or 16:3
if use 64 tea bags then how many cups of sugar so
turn 16:3 into fraction
16:3=16/3 or 3/16, it doesn't matter
then you want to find 64:x or 64/x or x/64

we know that 16/3=64/x because it tis an equivalent ratio
so 16/3=64/x
multiply both sdies by (3 times x)
16 times x times 3/3=64 times 3 times x/x
16 times x=64 times 3
16x=192
divide both sdies by 16
x=12
theanswer is 12 cups of sugar

Francis owns a camping supply store and just put in an order for flashlights and sleeping

Harlamova29_29 [7]

Answer:

The number of sleeping bags bought is 17.

Step-by-step explanation:

If we let "x" be the number of the sleeping bags that were bought, we can make the following equation....

(5x)(12) + (x)(45) = 1785

By solving the equation we get....

(5x)(12) + (x)(45) = 1785

60x + 45x = 1785
