Which triangle is obtuse?

Answer:

Because when a number is raised to negative indice, it automatically becomes a fraction of 1, with the number raised to the positive indice. If the original expression becomes the other..its still equivalent and equal to the same value-just changed to make solving more easier

Answer:

see expression

Step-by-step explanation:

Using the rule of exponents

[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex] , then

[tex]2^{-4}[/tex]

= [tex]\frac{1}{2^{4} }[/tex]

Thus

[tex]2^{-4}[/tex] and [tex]\frac{1}{2^{4} }[/tex] are equivalent expressions

Answer:

-8

64,−8→Negative

8x8=64

64/8=8

−8

Answer:

Let the actual pressure = x

The reading is x + 8 % , so the reading is 108% of the actual.

Divide the reading by 108% for the actual

39.42/1.08 = x

X = 36.5 psi

The actual pressure is 36.5 psi

Step-by-step explanation:

Answer:

A) 13:7 or 13 to 7

B) 6:7 or 6 to 7

Step-by-step explanation:

For the first one it is just the total number of marbles to the total blues marbles. For B it is the total red marbles to the total amount of blue marbles.

a) the ratio of all marbles in the bag to blue marbles is, 13/7

b) the ratio of red marbles to blue marbles is, 6/7

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

There are 6 red marbles and 7 blue marbles in a bag.

Hence, Total marbles = 6 + 7

                                   = 13

Thus, We get;

the ratio of all marbles in the bag to blue marbles is,

⇒ 13 / 7

And, the ratio of red marbles to blue marbles is,

⇒ 6 / 7

Answer:

[tex]2x+10y[/tex]

Step-by-step explanation:

Let's put this into the form of an equation.

[tex]4x+8y-2(x-y)[/tex]

Now, we'll distribute that -2.

[tex]4x+8y-2x+2y[/tex]

Then, combine like terms.

[tex]2x+10y[/tex]

Answer:

a. x = 11

b. 1 = 38

c . 2 = 55

Step-by-step explanation:

Here, we want to find the values of the marked angles

The two add up to give a right angle

Thus;

5x + 3x + 2 = 90

8x = 90-2

8x = 88

x = 88/8

x = 11

m1 = 3x + 5

substitute for x

m1 = 3(11) + 5 = 38

m2 = 5x

= 5(11) = 55

Step-by-step explanation:

If each grade has 20 girls in the grade, then that implies effectively that the ratios would apply via fractions, which are 3:4 and 4:5. As such, take both Fractions and increase them both to 20: 15:20 and 16:20.

Answer:

(- 6, 14 )

Step-by-step explanation:

Given the 2 equations

x + y = 8 → (1)

2x + y = 2 → (2)

Multiplying (1) by - 1 and adding to (2) will eliminate the y- term

- x - y = - 8 → (3)

Add (2) and (3) term by term to eliminate y, that is

x = - 6

Substitute x = - 6 into either of the 2 equations and evaluate for y

Substituting into (1)

- 6 + y = 8 ( add 6 to both sides )

y = 14

solution is (- 6, 14 )

Step-by-step explanation: For question 33 you have : (3x+3)+(6x+6)+90........ =180(sum of angles in a triangle is 180).

Question 34: (x+78)+(x+70)+44=180.....(same reason)

Question 35: (x+51)+(x+61)+90=180.....(same reason)

Question 36:(x+71)+(x+41)+90=180....(same reason).

g=92°

h=88°

m=89°

k=91°

Step-by-step explanation:

Answer:

h=88 g=92 m=89 k=91

Step-by-step explanation:

180-92=88

180-91=89

I'm not 100% certain about g and k, because I haven't done this in a while, but I'm pretty sure opposite angles equal the same thing. Also, a line is 180 degrees so just subtract the 180 from the number in the angle on the same line.

Step-by-step explanation:

this is the answer :)

Answer: ramiro,s method is the answer

Step-by-step explanation:

Answer:

Plug in your variables value.

Step-by-step explanation:

For your case, plug in -6 into the y slot

12(5+2y)= -(6-9y) +4y

12(5+2x-6)= -(6-9x-6)+4y see if that works!

Answer:

To check if the solution is right you substitute.

Step-by-step explanation:

So in this case you put y = - 6

So you substitute the y as - 6

12(5+2y) = - (6-9y)+4y

12(5+ (2 times - 6)) =(6-(9 times - 6)) + (4 times - 6)

12 times (5+-12) = (6- -6) + - 24

12 times - 7 = 12+-24

-84 = - 12

And that's how to check it basically.
