Answer:

14 7/24

Step-by-step explanation:

There are two different denominators here:  6 and 24.  The LCD is 24, and so 8 5/6 becomes 8 20/24.

Then the SUM of the two given mixed numbers is:

8 20/24 + 5 11/24 = 13 31/24, or, when properly reduced, 14 7/24

Answer:

Correct answer is the first one x^2 + 2x - 8

because (x + 4) (x - 2)

= x ^2 + 4x - 2x - 8

= x^2 + 2x - 8

Answer:

Answer:

x = 36.3

Step-by-step explanation:

Use sine

Sine 73 = x / 38

Sine of 73 is 0.956

Which means

0.956 = x / 38

Multiply 38 on both sides

36.328 = x

Round 36.328 to the nearest tenth

36.328 = 36.3

Answer:

In an isosceles right triangle, the equal sides make the right angle. ... Therefore each of those acute angles is 45°.

Step-by-step explanation:

Answer:

2 of the angles must be the same measure and one of the angle must be different from them.

Step-by-step explanation:

if 2 angles are 50 then one of them must be 80

Step-by-step explanation:

there is no picture or anything else, thus it is unknown and can not be figured out unless you repost this with a picture or the full question.

Step-by-step explanation:

Assuming the speed of car B to be x and the speed of car A to be x+20

156 = 208

x. x+20

156(x+20)= 208x

156x+3120=208x

3120=208x-156x

3120=52x

x=60

The speed of car A is (x)= 60

The speed of car B is(x+20)= 80

Answer:

[tex]\huge\colorbox{red}{Car\: A=80}\colorbox{blue}{Car B=60}[/tex]

Step-by-step explanation:

let the speed of car A be A

let the speed of car B be B

according to the first condition:

[tex]\quad A=B+20[/tex]

according to the second condition:

[tex]\quad 156(A)=208B[/tex]

therefore

[tex]\text{the speed of car A is 60+20=80}[/tex]

Step-by-step explanation:

Answer is 3 4/5 soils  in each flower bed.

Answer:

A. 33.3%

Step-by-step explanation:

On a dice, we have the numbers 1, 2, 3, 4, 5, and 6. The question is asking for the probability of anything greater than 4. This means we're trying to find the probability of rolling a 5 or a 6 since those are the only numbers greater than 4 on a dice. We can write this as a fraction.

There are six numbers total, so that will be the bottom of our fraction. We have two numbers that are greater than 4. This means we will write our fraction like so:

[tex]\frac{2}{6}[/tex]

Next, we can simplify the fraction by 2, leaving us with 1 over 3, like this:

[tex]\frac{2}{6} = \frac{1}{3}[/tex]

Finally, just divide the 1 by 3 to get 0.333, or 33.3% when you move the decimal two places to the right. Hope this helps!

Answer: 206

Step-by-step explanation:

Answer:

x-10

Step-by-step explanation:

you have to do what is in the parenthesis first. Do distributive property to

-(x-8)

-(x)-(-8)= -x+8

now you have 5-(3-x+8)

Do distributive property again

5-3+x-8

x-8+2

x-10

Answer:

12th triangular number is 78

50th triangular number is 1275

Step-by-step explanation:

12+1=13

12÷2=6

6x13=78

if you do this for 50 you get 1275

Answer:

Step-by-step explanation:

12 number

Wherever you see an n put in 12

12 (12 + 1)/2

12 * 13 / 2

6 * 13

78

The 12th triangular number is 78

50th triangular number

Again, wherever you see an n put in 50

n/2 * (n+ 1)

50/2 * (50 + 1)

25 * 51

1275

Answer:

b = 12.6

Step-by-step explanation:

a*2 + b*2 = c*2

6*2 + b*2 = 14*2

36 + b*2 = 196

Subtract 36 from both sides

36 + b*2 = 196

-36             -36

b*2 = 160

Find the square root of both

b = 12.64911064  or 12.6
