Answer:

The size is 37.5 degrees

Step-by-step explanation:

The total angle in the triangle is 180

Since the other two angles are congruent. it means that they are equal

Let us call each of the angles x

Mathematically,

x + x + 105 = 180

2x = 180-105

2x = 75

x = 75/2

x = 37.5

Answer:

$4x^{6}2y^{-2}$

Step-by-step explanation:

We can use a property I like to call SEi-F. (Subtract Exponents in a Fraction)

But first, there is an exponent outside of the parentheses in both places. We can use the Power of Parentheses to simplify and then use the SEi-F.

We will start with the x in the numerator.

3*4 = 12

Now for the y in the numerator.

4*4 = 16

Our new numerator is $4(2x^{12}y^{16})$

We do need to simplify the numerator one more time to get rid of the 4 outside the parentheses.

We will start with x's coefficient.

2*4 = 8

Now for y's coefficient.

1**4 = 4

*y seems to have no coefficient, but if so, it has a coefficient of 1. This applies to other variables.

Our final simplified numerator is $8x^{12}4y^{16}$ .

Repeat with the denominator.

Try it yourself!

Make sure that when you finish, you finish the fraction.

After completing the denominator, your completed fraction should be:

$\frac{8x^{12}4y^{16}}{4x^{6}2y^{18}}$

Now we can use the SEi-F to complete the problem.

Start with x.

8x - 4x = 4x

12 - 6 = 6

The first term is $4x^{6}$ .

Now for y.

4y - 2y = 2y

16 - 18 = -2

The second term is $2y^{-2}$

The complete, simplified equation is $4x^{6}2y^{-2}$ .

I could be wrong on the answer, but the work should be correct.

Hope this helps. Have a nice day. Oh, and one more thing. Surprised I'm not stealing points?

You lend out S5500 at 10% compounded monthly. If the debt is repaid in 18 months, what is the total owed at the time of repaymen

GrogVix [38]

Answer:

$6386.1140

Step-by-step explanation:

Using the compound interest formula :

A = P(1 + r/n) ^nt

P 5500 ; rate, r = 10% = 0.10 ; t = 18 months = 18/12 = 1.5 years,

Compounding times per period = 12 (monthly)

A = 5500(1 + 0.1/12)^12*1.5

A = 5500(1 + 0.0083333)^18

A = 5500(1.0083333)^18

A = 5500 * 1.1611116

A = 6386.1140

Hence, amount to be repaid = $6386.1140

Determine where f(x) = x2 + 2x - 8 intersects the x-axis.

V125BC [204]

Let f(x) =0.
${x}^{2} + 2x - 8 = 0 \\ (x + 4)(x - 2) = 0 \\ x + 4 = 0 \\ x = - 4 \\ x - 2 = 0 \\ x = 2$
x=-4, 2

I need help really bad :(

Darya [45]

Answer:

5x+ 13x = 180

Step-by-step explanation:

The two angles form a straight line, which is equal to 180 degrees

We can add the angles together which will total 180

5x+ 13x = 180

UPS charges $6.00 for the first pound, $1.00 for the second pound, and $0.15 for each additional pound. FedEx charges $4.00 for

Anna35 [415]

Answer:

The two costs will be the same at 12 pounds.

Step-by-step explanation:

Let p be the number of additional pounds.

UPS cost = 7 + 0.15p

FedEx cost = 6 + 0.25p

Make them equal

7 + 0.15p = 6 + 0.25p

0.10p = 1

p = 10

So, total weight for the cost to be equal is 12.

UPS Cost = 8.50

FedEx Cost = 8.50
