A machine prints 8 banners in 120 seconds how many seconds does it take to print one Banner

2 answers:

8 0

So all we have to do is divide 120 by 8 so 120/8= 15

Do you understand why we do that? It’s because there are 120 seconds needed to print 8 banners so dividing 120 by 8 will get you the time for one

A triangle has a height that is 2 inches more than three times the base and an area of 60 in. Find the base and the height of th

const2013 [10]

Answer:

Height = 20, Base = 6

Step-by-step explanation:

The area of a triangle is $\frac{bh}{2}$

where b is the base and h is the height

$H = 3B + 2\\\frac{B(3B + 2)}{2}=60\\\\3B^2 + 2B = 120\\3B^2+2B - 120=0\\$

We can factor by grouping

$3B^2 - 18B + 20B - 120 = 0\\3B(B - 6) + 20(B-6) = 0\\GCF the (B-6)\\(B-6)(3B+20)=0\\B = 6, B = \frac{-20}{3}$

Length can only be positive, so we know that the base is 6 in

The height must be 2 + 3(6) = 20

Height = 20, Base = 6

On the first day it was posted online, a music video got 390 views. The number of

aleksley [76]

Answer:

The answer is 7212 views

Step-by-step explanation:

<h3>Given;</h3>

A music video got 390 views.
The number of views that the video got each day increased by 30% per day.

Total views did the video get over the course of the first 13 days

So, For the first day the number of views is 390

Second Day

30% increased of total views

390 × 30 ÷ 100 = 11.7 = 12

390 + 12 = 402

Third Day

30% increased of total views

402 × 30 ÷ 100 = 120.6 = 121

402 + 121 = 523

Fourth Day

30% increased of total views

523 × 30 ÷ 100 = 156.9 = 157

523 + 157 = 680

Fifth Day

30% increased of total views

680 × 30 ÷ 100 = 204

680 + 204 = 884

Sixth Day

30% increased of total views

884 × 30 ÷ 100 = 265.2 = 265

884 + 265 = 1149

Seventh Day

30% increased of total views

1149 × 30 ÷ 100 = 344.7 = 345

1149 + 345 = 1494

Eight Day

30% increased of total views

1494 × 30 ÷ 100 = 448.2 = 448

1494 + 448 = 1942

Ninth Day

30% increased of total views

1942 × 30 ÷ 100 = 582.6 = 583

1942 + 583 = 2525

Tenth Day

30% increased of total views

2525 × 30 ÷ 100 = 757.5 = 758

2525 + 758 = 3283

Eleventh Day

30% increased of total views

3283 × 30 ÷ 100 = 984.9 = 985

3283 + 985 = 4268

Twelth Day

30% increased of total views

4268 × 30 ÷ 100 = 1280.4 = 1280

4268 + 1280 = 5548

Thirteenth Day

30% increased of total views

5548 × 30 ÷ 100 = 1664.4 = 1664

5548 + 1664 = 7212

Thus, Total views did the video get over the course of the first 13 days is 7212 Views.

Smallest of 3 consecutive positive intergers if the product of the smaller two intergers is 5 less than 5 times the largest inte

amm1812

What a delightful little problem ! (Partly because I could see
right away how to do it, and had the answer in a few minutes,
after a lot of impressive-looking algebra on my scratch-paper.)

Three consecutive integers are . . . x, x+1, and x+2

The smallest two are . . . x and x+1
 Their product is . . . . . x(x+1)

5 times the largest one is . . . 5(x+2)
 5 less than that is . . . . . . 5(x+2)-5

Now, the conditions of the problem say that x (x + 1) = 5 (x+2) - 5
THAT's the equation we have to solve, to find 'x' .

 Eliminate parentheses: x² + x = 5x + 10 - 5
 Combine like terms: x² + x = 5x + 5
Subtract 5x from each side: x² - 4x = 5
Subtract 5 from each side: x² - 4x - 5 = 0

You could solve that by factoring it, or use the quadratic equation.

Factored, it says that (x + 1) (x - 5) = 0

From which x = -1
 and x = +5

We only want the positive results, so our three consecutive integers are

 5, 6, and 7 .

To answer the question, the smallest one is 5 .

Check:

 5 x 6 ? = ? (7 x 5) - 5

 30 ? = ? (35) - 5

 30 = 30

 yay !
