State if each triangle is a right triangle.

Answer:

The answer is 27t - 12.

Step-by-step explanation:

1) Remove parentheses.

[tex] \frac{1}{2} \times 18t + 2t \times 9 - 12[/tex]

2) Use this rule: a/b × c/d = ac/bd.

[tex] \frac{1 \times 18t}{2} + 2t \times 9 - 12[/tex]

3) Simplify 1 × 18t to 18t.

[tex] \frac{18t}{2} + 2t \times 9 - 12[/tex]

4) Simplify 18t/2 to 9t.

[tex]9t + 2t \times 9 - 12[/tex]

5) Simplify 2t × 9 to 18t.

[tex]9t + 18t - 12[/tex]

6) Collect like terms.

[tex](9t + 18t) - 12[/tex]

7) Simplify.

[tex]27t - 12[/tex]

Thus, the answer is 27t - 12.

Answer:

first box: F, second box: 25

Step-by-step explanation:

We are substituting "25" for "C" because the problem says to convert 25 degrees Celsius to (unknown) Fahrenheit

5/9(F - 32) = 25

I would then multiply both sides of the equation by 9 to get rid of the fraction, giving:

5(F -32) = 225

then divide both sides by 5

F - 32 = 45

then add 32 to both sides

F = 77

Answer:

  G: $27

  H: $25

Step-by-step explanation:

In each case, the "initial cost" is the cost when the number of hours is zero.

For company G, it is ...

  c = 27 + 10·0

  c = 27

For company H, it is 25 (corresponds to Hours = 0).

__

The initial costs are ...

  G: $27

  H: $25

_____

Additional comment

The cost per hour is found from the equation by looking at the coefficient of h. It is $10 per hour for Company G.

The cost per hour is found from the table by looking at the increase when the number of hours increases by 1. For 1 hour, the cost goes from 25 to 32, an increase of $7 for 1 hour. The cost is $7 per hour for Company H.

Answer:

540 stamps

Step-by-step explanation:

Percentage of foreign stamps = (100-70)% = 30%

Number of foreign stamps = 30% of 1800

                                           [tex]=\frac{30}{100}*1800\\\\=30*18\\= 540[/tex]

Answer:

D (last one)

Step-by-step explanation:

70/100 x 1800

= 1260 local stamps

1800 - 1260

= 540 foreign stamps

The diameter of the pond is 11.54 m.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Given that at the center of a circular pond, there is apole of 11.63 high above the surface of water from a point on the edge of a pond.

A man of 1. 62 m high observed the angle of elevation of the top of the pole and found to be 60degree

We need to find the diameter.

tan60=11.63-1.62/r

r=10/tan60

r=10/√3

r=5.77

We know that diameter is twice the radius

d=2r

d=2(5.77)

d=11.54

Hence, the diameter of the pond is 11.54 m.

Answer:

(4,-1)

Step-by-step explanation:

You can solve this system of equations in a couple of different ways, but I'm going to use the elimination method. If you're solving a system of equations using elimination, you want to have one variable cancel out. In this case, we don't have to change anything because -3y and 3y will already cancel out if we add the two equations together. You can both add or subtract, but it's easiest to add in this case. The equation will be set up like this: 2x-3y=11

                                                                                                      +  7x+3y=25

                                                                                                         --------------

After you add them together, you should get 9x=36, which you can solve by dividing both sides by 9. Then, you'll get x=4. This is your x-coordinate. Next, you want to get your y-coordinate, so you can substitute 4 into one of the two equations for x and solve for y. This will get you -1 for y. I'd also recommend checking your answer.

Do you still need the answer?

Step-by-step explanation:

Answer:

Which language is this I don't understand

Answer: X=-3.

Anne was correct at fist, but likely didn’t solve the rest of the equation. The correct answer is X=-3, from 5(2x - 3)= 20x + 15, simplified by the distributive property going to 10x - 15 = 20x + 15. You then subtract +15 from the right side, or left side if you want to have a more positive answer, though it depends. That leaves you with 10x - 30 = 20x.  You subtract 10x from itself and from 20x. Then you have -30 = 10x. You divide 10x by -30, and you get -3. Therefore, X = -3.
