what is the answer to 7 1/3 + 5 4/5

I started by labeling the right angle (Angle C) 90º. Next, I wrote down everything in one equation.

2x + 90 + 3x - 20 = 180º (180 degrees in a triangle)

Next, I add 20 on both sides.

2x + 90 + 3x = 200º

I combine like terms (2x and 3x)

5x + 90 = 200º

I subtract 90 from both sides.

5x = 110º

Divide 110 by 5 to get x.

x = 22

======

For problem two, I label all the angles I know.

49º + 80º + r = 180º

I add 80 and 49.

129º + r = 180º

I subtract 180 and 129 and get 51º, which is your angle for R.

For angle X, you know that angle R plus angle X equals half of a circle, which is 180º

We know from before that 129º is 180º without R, so X is 129º

I hope this helps! Let me know if I'm wrong!

Answer:

x = 7

Step-by-step explanation:

Rearrange the equation to make x the subject.

Original:

7x + 3 = 52

subtract 3 from both sides

7x = 52 -3

7x = 49

Divide both sides by 7

x = 49/7

x = 7

Answer:

0.9

Step-by-step explanation:

Volume can be defined as the capacity of a given container or a certain object.

The radius of the cone is 2 inches.

From the question, we are given the following parameters:

The height of the cone = 12 inches

The volume of the cone =  16 π in³

The formula to find the radius of the cone is given as:

√3V/πh

= √ 3 x 16π / π x 12

= 2 inches

Therefore, the radius of the cone is 2 inches.

could you give me brainliest pls?

Answer:

I get the answer 52°......................

Step-by-step explanation:

it is a right-angled triangle, so the side lengths need to fulfill the Pythagoras rule :

c² = a² + b²

where c is the Hypotenuse, the baseline opposite of the 90 degree angle. and a and b (often called legs) are the sides "enclosing" the 90 degree angle.

so, we have

20² = a² + 12²

400 = a² + 144

a² = 256

a = 16

FYI - we could have picked the right answer also by eliminating the wrong given answer options.

as this is a right-angled triangle :

a cannot be longer than the baseline (20).

that eliminates already the first 2 options.

and then look at the picture : a cannot be shorter than b (the other side line (12)).

that eliminates the third option.

0+ 5x =13

0 - 13= -5x

-13= -5x

-13/-5 = -5x/-5

x = 13/5

y intercept, replace x with 0

y+5x=13

y+5(0)=13

y+0=13

y =13

Answer:

77/180

Step-by-step explanation:

x = 0.42777....

Multiply by 1000   (the number of digits in decimal)

1000x = 427.7777......

  100x =  42.7777......    {Now subtract}

900x =  385

      x = 385/900

x = 77/180

0.76                 19 divided by 27= 0.76

Answer:$22.50

Step-by-step explanation:

The three friends already paid the entrance fee. The question asks how much MORE will they pay for 5 MORE rides (8-3 rides). Since tickets are $1.50 each, and we have 3 people:

($1.50/ticket)*(5 tickets/person)*(3 persons) = $22.50 more.

[Note how the units cancel, leaving just $]

Answer:

simple ( principal *rate*time)/100.

3500*4*10/100 = 1400 interest

account balance =3500+1400=4900

compound p(1+r)^t

3500(1+.04)^10 =3500* 1.480=5180

interest earned = 5180-3500= 1680

how much more interest. ; 1680-1400=280

Answer:

Step-by-step explanation:

Simple Interest:

Simple Interest formula is S.I. = P × r × t

Interest Eared: $3,500 × 0.04 × 10 = $1,400

Account Balance formula is A = P ( 1 + rt )

Account Balance: $3,500 + $1,400 = $4,900

Compound Interest:

Compound Interest formula: [tex]A =P(1+r)^{t}[/tex]

Account balance: $5,180.85

Interest Earned: $5,180.85 - 3,500.00 = $1,680.85
