1) 6х - 4 = 5х - 11 ; ??


2) 0,3( х -2) = 0,6 + 0,2(х+4) ; ??

Answer:

5

Step-by-step explanation:

This uses the Pythagorean theorem ([tex]f^2 + g^{2} =h^2[/tex]).  So you would take your values 3 and 4 and plug them into the equation.  [tex]3^2+4^2=h^2[/tex].  This becomes [tex]9+16=h^2[/tex].  Simplify and this becomes [tex]25=h^2[/tex].  If you take the square root of both sides you will end with 5 = h.  Therefore your answer is 5.

Answer:

H=5

Step-by-step explanation:

Since it's a right triangle, you can use the Pythagorean Theorem which is [tex]a^2 + b^2 = c^2[/tex] or in this case: [tex]f^2 + g^2 = h^2[/tex]

Substitute 3 in for f and 4 in for g: [tex]3^2 + 4^2 = h^2[/tex]

Add 9 and 16 together, it's 25 and then find the square root of 25 and the square root of h and the answer is 5

[tex]f^2 + g^2=h^2\\3^2 + 4^2 = h^2\\9 + 16 = h^2\\25 = h^2\\\sqrt25 = \sqrt h^2\\5 = h[/tex]

Answer:

36=3×2×2×3

48=2×2×2×2×3

Explanation:

Step 1: Divide the given number by the smallest prime number.

36/3=12. (1)

48/2=24. (2)

Step 2: Again, divide the quotient by the smallest prime number.

12/2=6. (1)

24/2=12. (2)

Step 3: Repeat the process, until the quotient becomes 1.

6/2= 3. (1)

12/2=6 (2)

3/3=1 (1)

6/2=3 (2)

3/3=1. (2)

Step 4: Finally, multiply all the prime factors.

36=3×2×2×3

48=2×2×2×2×3

Answer:

36 = 2 × 2× 3 ×3

Answer:

3.4, 1/4, 12%, -0.01, -26.1

Step-by-step explanation:

The simplest way to do these type of problems is to convert all of the numbers into either a fraction, decimal, or a percentage. In my opinion, it is easier to use a percentage here.

12% is already a percentage

-0.01 = -1%

1/4 = 25%

3.4 = 340%

-26.1 = -2610%

Now that the rational numbers are all in the same unit, it is easier to sort them. In the end, we get this list (from greatest to least):

3.4, 1/4, 12%, -0.01, -26.1

FINAL ANSWER: 3.4, 1/4, 12%, -0.01, -26.1

Answer: Standard deviation

Step-by-step explanation: The standard deviation is the average amount of variability in your dataset. It tells you, on average, how far each score lies from the mean. The larger the standard deviation, the more variable the data set is.

Answer:

No.

Step-by-step explanation:

The order of operations in both problems are different, giving two very different results. Therefore, they are unequal.

The compound inequality for the area written in terms of x is 100 ≤ 20x ≤ 1,000.

We know that, the area of rectangle is given by:

Area = Length × Breadth

Now, we will substitute the values of length as 4x and breadth as 5 in the formula:

= 4x × 5

= 20x

Now. we will substitute this value in the inequality 100 ≤ A ≤ 1,000 to get the compound inequality:

100 ≤ 20 x ≤ 1,000.

Therefore, the compound inequality for the area written in terms of x is 100 ≤ 20x ≤ 1,000.

Answer:

x = 60°

Step-by-step explanation:

See picture below.  When two parallel lines are cut by a transversal there are some special relationships.

Answer:

x = 60°

Step-by-step explanation:

∠ ABO and ∠ CBO are a linear pair and sum to 180° , that is

∠ ABO + ∠ CBO = 180°

150° + ∠ CBO = 180° ( subtract 150° from both sides )

∠ CBO = 30°

∠ XYO and ∠ CBO are alternate angles and are congruent , so

∠ XYO = 30°

∠ XOY and ∠ COY are a linear pair and sum to 180° , then

∠ XOY + ∠ COY = 180°

∠ XOY + 90° = 180° ( subtract 90° from both sides )

∠ XOY = 90°

the sum of the 3 angles in Δ XOY = 180° , that is

x + 90° + 30° = 180°

x + 120° = 180° ( subtract 120° from both sides )

x = 60°

2. 2/12 = 1/6 (simplified)

3. 12/72 = 1/6 (simplified)

Hope this helps :)

Answer:

[tex]\frac{5}{6} * 15 = 12\frac{1}{2}[/tex]

[tex]\frac{2}{3} * \frac{1}{4} = \frac{1}{6}[/tex]

[tex]\frac{4}{9} * \frac{3}{8} = \frac{1}{6}[/tex]

Step-by-step explanation:

[tex]\frac{5}{6} * 15 = \frac{5 * 15}{6} = \frac{75}{6}\\[/tex]

Reduce the fraction by diving both sides by the common factor.

[tex]\frac{75}{6} = \frac{75 / 3}{6/3} = \frac{25}{2}[/tex]

To convert the improper fraction to a mixed fraction, divide the numerator (25) by the denominator (2), put the whole part of the result in front and the remainder in place of the original numerator.

25 / 2 = 12 with remainder of 1

[tex]\frac{25}{2} = 12\frac{1}{2}[/tex]

[tex]\frac{2}{3} * \frac{1}{4} = \frac{2 * 1}{3 * 4} = \frac{2}{12} = \frac{2/2}{12/2} = \frac{1}{6}[/tex]

[tex]\frac{4}{9} * \frac{3}{8} = \frac{4 * 3}{9 * 8} = \frac{12}{72} = \frac{12 / 12}{72 / 12} = \frac{1}{6}[/tex]

Step-by-step explanation:

4 consecutive odd integers means we start with x, then have x+2, x+4 and then x+6.

and then we have

-24 = x + x+2 + x+4 + x+6 = 4x + 12

4x = -36

x = -9

x+2 = -7

x+4 = -5

x+6 = -3

The equation could be used to find the maximum speed of a hippopotamus h is C. 75 = 3h + 18

The question has to do with linear equation

A linear equation is a mathematical expression in which the highest power of the unknown is 1.

Let

Given that the maximum speed, in miles per hour, of a cheetah is 18 more than 3 times  the maximum speed of the hippopotamus

Now, since the maximum speed of the hippopotamus is h, 3 times the maximum speed of the hippopotamus is 3h.

Since the cheetah is 18 more than 3 times  the maximum speed of the hippopotamus, we have that

x = 3h + 18

Substituting x = 75 into the equation, we have

75 = 3h + 18

So, the equation could be used to find the maximum speed of a hippopotamus h is C. 75 = 3h + 18

Answer:

Step-by-step explanation:

Answer:

A)  |x - 1200| = 22

B)  x = 1222,  x = 1178

C)  Minimum = $1,178

    Maximum = $1,222

Step-by-step explanation:

Define the variable:

Given information:

If the artist plans to sell $300 of prints each week, then she plans to sell approx $1200 of prints each month, since there are approximately 4 weeks in each month.

If she is within $22 of her goal, this month then:

⇒ |x - 1200| = 22

To solve an equation containing an absolute value, set the contents of the absolute value equal to both the positive and negative value of the number on the other side of the equation, then solve both equations:

Equation 1

⇒ x - 1200 = 22

⇒ x - 1200 + 1200 = 22 + 1200

⇒ x = 1222

Equation 2

⇒ x - 1200 = -22

⇒ x - 1200 + 1200 = -22 + 1200

⇒ x = 1178

Price: $178.57

30% off: -$53.57

Sale Price: $125.00

Step-by-step explanation:

She buys each shirt for $100.

She wants to make a profit of 25%.

25% of $100 = 0.25 × $100 = $125

She must sell the shirt at $125.

She wants to mark the shirt at a higher price than $125, so that after the 30% discount, she will still sell it for $125.

Call the higher price x.

x - 30% of x = 125

x - 0.3x = 125

0.7x = 125

x = 125/0.7

x = 178.57

The formula for the function that approximates the ground roll for a fully Cessna 172 at an elevation of x is y = 585(1.00009)x .

What is angle of elevation ?

Let the formula for the exponential function that approximates the ground roll for a fully loaded Cessna 172 at an elevation of x be

y =A(B)x ....(1)

Here,

A = ground roll at x =0,

B = growth factor.

Since at x =0, , Ground roll is = A = 585 ft ....(2)

On putting A = 585 in equation (1), we get

y = 585(B)x ....(3)

Now, at elivation of x = 1000 ft ,

Ground roll y = 640 ft.

So, putting these values in equation (3), to get

640 = 585(B)1000

Reversing the sides to get

585(B)1000 = 640

Or B1000 = 640/585

Or B1000 = 1.09017094

Or B = (1.09017094)1/1000

Or B = 1.00009 .....(4)

On putting the value of B  in equation (3), we get

y = 585(1.00009)x

Hence, the formula for the function that approximates the ground roll for a fully Cessna 172 at an elevation of x is y = 585(1.00009)x .

The measure of angle EFH, m ∠EFH is 71°

The measure of angle EFG, m ∠EFG is 142°

From the question, we are to determine the measure of angle EFH and angle EFG

From the given information, we have that

FH bisects ∠EFG.

Thus, we can write that

m ∠EFH = m ∠GFH

From the given information,

m ∠GFH = 71°

∴ m ∠EFH = 71°

Also,

Since FH bisects ∠EFG

Then,

m ∠EFH + m ∠GFH = m ∠EFG

71° + 71° = m ∠EFG

142° = m ∠EFG

m ∠EFG = 142°
