One number is 33 times a first number. a third number is 100 more than the first number. if the sum of the three numbers is 3103
kherson [118]
Create some expressions.

1# number: x

2# number: 33x

3# number: 100 + x


this all equals to 310310 when added so

x+33x+(x+100) = 310310

Solve what you know first then rearrange it.

34x + x + 100 = 310310

35x = 310310-100

35x = 310210

x = 310210/35

x = 8863.142857

Substitute the x into the expressions made and you'll find the 2# and 3# number. You've already found the 1# number since it's only x.

Isha can buy 3 sweatshirts for a total of $45.How much would it cost if she were to buy 5 sweatshirts at the same price
fiasKO [112]
X = cost of 1 sweat shirt

3x = 45
x = 15

5x = 5(15) = 75

It would cost $75. Hope this helps!

A triangle has side lengths of 10, 11, and 15 . what type of triangle is it?
Trava [24]
Answer: scalene and obtuse

Justification:

You can find the angles using the law of cosine:

c^2 = a^2 + b^2 - 2abcos(γ)

=> cos(γ) = [a^2 + b^2 - c^2] / (2ab)

1) cos(γ) = [10^2 + 11^2 - 15^2] / (2*10*11) = - 0.0181818

=> γ = arccos(-0.0181818} ≈ 91°

2) cos(α) = [b^2 + c^2 - a^2 ] / 2bc = [11^2 + 15^2 - 10^2] / (2*11*15] = 0.7454545

=> α = arccos(0.7454545) ≈ 41.8°

3) cos(β) = [a^2 + c^2 - b^2] / (2ac) = [10^2 + 15^2 - 11^2] /(2*10*15) = 0.68

=> β = arccos(0.68) ≈ 47.2°

4) Verification: 91° + 41.8° + 47.2° = 180°

5) The triangles with the three different sides are called scalenes (which you can tell with only the measures of the sides).

6) The triangles with one angle greater than 90° are called obtuse.

So, the triangle is scalene and obtuse.

Use scientific notation to estimate the number of inches in 1,225 miles
madam [21]
First, find the number of inches
<span>1225 Miles = 77616000 Inches

then, move the decimal to until you have a ones place.    </span>
<span>77616000.    the decimal for this number moves to the left SEVEN places.
you end up with 7.7616000
</span>
it will look like this:

7.8 * 10^7

I rounded to the .8 because you didn't state how many significant figures, but it could easily be 7.76 * 10^7

the exponent above the 10 will tell you how many places to move. to get back to your original number, move it back to the right seven places. Of course, you would have to place hold the numbers with 0s. If it were negative, you would move the decimal the opposite way.
