c2-1/4=0 equation maths ​

Answer:

19

Step-by-step explanation:

You need to find the biggest and smallest number; 25,6

Then you subtract 6 from 25

25-6=19

I hope this helps!!!!!!!

Answer:

19

Step-by-step explanation:

The range is the difference between the highest and the lowest number

So 6, 12, 18, 20, 25 and 25-6 = 19

Answer:

3/2 or 1 1/2

Step-by-step explanation:

5÷3 1/3

5/1 ÷ 10/3 because you have to get it into an improper fraction form in order to divide

5/1 × 3/10 because you have to multiply the first number by the reciprocal

5  and 10 cancel out so you would have 2 at the bottom

3/2 or 1 1/2

Answer:2/21

Step-by-step explanation:

2 x 1      2

——-   =. -

7 x 3.    21

Answer:

x=8+4y

Step-by-step explanation:

Add 8y to both sides:

2x=16+8y

Divide both sides by 2:

x=8+4y

Answer:

choose the first one.

Answer:

Use your calculator

Step-by-step explanation:

Press the cos button COS(  - should look like that... Then fill it out COS(30) make sure to add the closed parenthesis so you dont get an error. And then BAM you got your answer and dont have to look anymore up. XD

Answer:

Step-by-step explanation:

let x be the unknown volume

5/7=50/x

x=70

Answer:

137.2 m³

Step-by-step explanation:

Given the ratio of sides a : b , then

ratio of volumes = a³ : b³

Here ratio of sides = 5 : 7 , then

ratio of volumes = 5³ : 7³ = 125 : 343

let x be the volume of the larger prism then by proportion

[tex]\frac{50}{125}[/tex] = [tex]\frac{x}{343}[/tex] ( cross- multiply )

125x = 17150 ( divide both sides by 125 )

x = 137.2

That is volume of larger prism is 137.2 m³

Answer:

5

Step-by-step explanation:

9+6=15

15/3=5

Step-by-step explanation:

[tex] \frac{a + b}{c} = \frac{9 + 6}{3} = \frac{15}{3} = 5 \: ans[/tex]

Answer:

10000

Step-by-step explanation:

50 times 200

5 times 2 is 10

add three zeros: 10000

Note: Your answer choices remain a little unclear. But, I have solved the concept and solution, so you can easily figure it out.

Answer:

[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)[/tex]

solving the expression

[tex]=-7x^0+5x^2-x+6-\left(-8x^2+x+3\right)[/tex]

apply the rule: [tex]a^0=1,\:a\ne \:0[/tex]

[tex]=-7+5x^2-x+6-\left(-8x^2+x+3\right)[/tex]

[tex]=-7+5x^2-x+6+8x^2-x-3[/tex]

simplify

[tex]=13x^2-2x-4[/tex]

Therefore, the simplified form is:

[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4[/tex]

Note: Your answer choices remain a little unclear. But, I have solved the concept and solution, so you can easily figure it out.

Answer: if its a multiple of a 345 triangle then its congruent x is 36 if othersides ate multiples of 20 ie

Sides are

60 80 100 is a 345 right triangle

Step-by-step explanation:

Answer:

68.75

Step-by-step explanation:

Measure the length of the parallel sides and add them together. Then multiply this number by the height of the area. Then multiply by ½ or divide by two to find the square footage of the trapezoid.  

13.6 + 5.9= 19.5

19.5 + 8 = 27.5

27.5 x 5 = 137.5

137.5 x 1/2 = 68.75

Well first, you have to know that there are 12 inches in a foot so, that's 12 / 3 = 4, so that means that for every foot, there are 4 books. The books are 5 feet tall so 4 x 5 = 20. Your answer is: 20 books are in a stack.

Answer:

Step-by-step explanation: I would do 5x12 because there are 12 inches in one foot so 5x12 is 60 so there is 60 inches

Answer:

13.7

Step-by-step explanation:

Pythagorean theorem converse

Answer:

The value of x is 13.7.

Step-by-step explanation:

☆We are going to use the Pythagorean theorem to solve this.

☆Pythagorean Theorem:

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

☆Remmeber: a = leg, b = leg, c = hypotenuse or the diagonal.

☆Let's plug in according to the pythagorean theorem and solve!

[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {x}^{2} + {9.2}^{2} = {16.5}^{2} \\ {x}^{2} + 84.64 = 272.25 \\ \frac{ \: \: \: \: \: \: \: \: - 84.64 = - 84.64}{ {x}^{2} = \sqrt{187.61} } \\ x = 13.7[/tex]

Step-by-step explanation:

When 2 variables are inversely proportional to each other, their product is a constant.

Since Q and V³ are inversely proportional to one another, QV³ = k. (B)

Answer:

Jordin weighs 96 pounds

Step-by-step explanation:

The Mean Value of a Data Set

The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:

[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]

Where xi is the value of each data and n is the total number of values.

We are given the average weight of n=5 marathon runners:

[tex]\bar x=92[/tex]

Multiplying the formula by n and expanding the sum:

[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]

We are given the weighs of four of the runners:

[tex]5*92=89+95+90+90+x_5[/tex]

[tex]460=364+x_5[/tex]

Solving for x5:

[tex]x_5 = 460-364=96[/tex]
