Please answer this ASAP!!!

Step-by-step explanation:

20 % of 1.30 is 1.30×20 / 100 = 0.26

1.30 increased by 20% is 1.30+0.26= 1.56

No, 1/2x+3/4-5/8x-7/8 and 1/8(x+1) are not equivalent expressions.

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

The given expression is 1/2 x+3/4-5/8 x-7/8

Now, 1/2 x-5/8 x+3/4-7/8

-1/8 x- 1/8

-1/8(x+1)

Therefore, the equivalent expression for the given expression is -1/8(x+1).

Answer:

b=9 and b=-21

Step-by-step explanation:

first step: move 195 to the other side by adding to get:

b^2+12b=189

now to find the constant you take the b value which is 12 divide that by 2 and square it. then add the product to both sides. 12/2=6, 6^2=36

b^2+12b+36=189+36

next factor b^2+12b+36.

(b+6)^2=225

square root both sides to get:

b+6=15 and b+6=-15

solve by subracting 6 to both sides and you get the 2 final answers.

b=9 and b=-21

Answer:

Mean: 83.571428571429

Median: 85

Mode: 70

Step-by-step explanation:

The mean is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.

The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median. If there are 2 numbers in the middle, the median is the average of those 2 numbers.

The mode is the number in a data set that occurs most frequently. Count how many times each number occurs in the data set. The mode is the number with the highest tally. It's ok if there is more than one mode. And if all numbers occur the same number of times there is no mode.

Answer:

Median 85

Mode 70

Mean 83.571 rounded = 83.6

Answer:  2144

Step-by-step explanation:

v = 4/3pir³

v = 4/3 (3.14) (8)³

v = 4/3 (3.14)(512)

v ≈ 2144

Answer:

2,143.57 cubit units.

Step-by-step explanation:

To find the volume of the sphere, use the formula given below.

Volume = 4/3π r³

Use this formula, the value given for the radius, and 3.14 for  to find the volume.

Volume = 4/3π r³

             ~~ 4/3 (3.14) (8 units)³

             ~~ 2,143.57 cubic units

Therefore, the approximate volume of the sphere is 2,143.57 cubic units.

Answer:

5 days

Step-by-step explanation:

60 ÷ 12 = x

x represents the amount of days

the elephant get 12 lbs. per day

60 is the total amount of lbs.

Answer: 5 days

Step-by-step explanation:

Okay, so we use the equation 12x=60. She gives the elephant 12 peanuts a day but we don't know how many days so we put x.

Now to solve this, we must divided 12 on both sides and get 5.

12x=60

÷12 ÷12

x=5

Answer:

x=20

Step-by-step explanation:

pentagon= 3 triangles could be made-> 3 x 180

total angle = 540

540=25x+40

500=25x

-6^2

Step-by-step explanation:

-6 x -6 = 36

Answer:

(−6)²

Step-by-step explanation:

(−6)⋅(−6)

This means the numbers are being multiplied.

A number is being multiplied by the same number. You can write an exponent for the number of times it's being multiplied by itself.

Example:

x = x¹

x·x = x²

x·x·x = x³

You are multiplying (−6) twice.

(−6)⋅(−6) = (−6)²

Answer:

x= 21/15

if you need to reduce it would be x=7/5

Step-by-step explanation:

12x-15 =6-3x

add 3x to both sides

15x- 15 = 6

now add 15 to both sides

15x = 21

lastly divide both sides by 15

x= 21/15

if you need to reduce it would be x=7/5

Answer:

x = 7/5 or 1.4

Step-by-step explanation:

12x - 15 = 6 - 3x             Need to move one variable term to the other side to

+3x              + 3x         isolate it on one side

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

15x - 15 = 6                   need to +15 to isolate the variable term

     +15   +15

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

15/15x = 21/15 (simplify 21/15 = 7/5)   need to divide by 15 to isolate x

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

x = 7/5 or 1.4

Answer:

Step-by-step explanation:

The measure of an inscribed angle (QTR) is half the measure of the arc it intercepts. The measure of an arc is the same as the measure of the central angle it intercepts. So, we have ...

  ∠QSR = 2×∠QTR

  ∠QSR = 2×39°

  ∠QSR = 78°

__

Sides SQ and SR are radii of circle S, so are the same length. That means triangle QRS is an isosceles triangle and the base angles SQR and SRQ are congruent. The sum of angles in a triangle is 180°, so we have ...

  ∠QSR + 2(∠SQR) = 180°

  78° + 2(∠SQR) = 180° . . . . fill in the value we know

  2(∠SQR) = 102° . . . . . . . . . subtract 78°

  ∠SQR = 51° . . . . . . . . . . . . .divide by 2
