184 is what percent more than 148

Answer:

the answer to the question is c

The equivalent expression to the equation is A = √ ( x² - 9 )

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It displays the similarity of the connections between the phrases on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = √ ( x + 3 ) .√( x - 3 )

Now , on simplifying the roots of the equation , we get

A = √ ( x + 3 ) ( x - 3 )

The value of ( a + b ) ( a - b ) = a² - b²

So , on further simplification , we get

A = √ ( x² - 9 )

Therefore , the equivalent expression of A is √ ( x² - 9 )

Hence , the equation is A = √ ( x² - 9 )

The direction of both forces will be on the positive x-axis. And the resultant force is 185.64 Newtons.

The product of the mass and acceleration is known as force.

Peyton and Tanner were lifting a large boulder and relocating it within their property.

Peyton is pushing the boulder with a force of 110 newtons at an angle of 55° with respect to the positive x-axis.

Tanner is pulling the boulder with a force of 165 newtons at an angle of 42° with respect to the positive x-axis.

The direction of both forces will be on the positive x-axis.

The pushing force will be

→ 110 × cos 55° = 63.09 N

The pulling force will be

→ 165 × cos 42° = 122.62 N

Then the resultant force will be

Resultant force = 63.02 + 122.62 = 185.64 N

Answer:

0.54035

Step-by-step explanation:

Given that :

Mean, m = 66 inches

Standard deviation, s = 2.5 inches

P(65 < X < 69)

P(X < 69) - P(X < 65)

((69 - 66) / 2.5) - ((65 - 66) / 2.5)

P(Z <(3/ 2.5)) - P(Z <(-1 / 2.5))

P(Z < 1.2) - P(Z < - 0.4)

0.88493 - 0.34458

Step-by-step explanation:

Let's call the missing card number "x".

The mean is the sum divided by the number of elements, so we know that:

[tex]\frac{12 + 6 + 15 + x}{4} = 10\\~\\12 + 6 + 15 + x = 40\\33 + x = 40\\x = 7[/tex]

The number on the 4th card is 7 according to the given question when The mean of the 4 numbers on Ed's cards is 10

To work out the number on the 4th card, we can use the information given about the mean of the four numbers.

Mean is calculated by summing all the values and then dividing by the number of values. In this case, the mean is 10 and there are four numbers.

Given:

Mean = 10

Number of cards = 4

To find the sum of the four numbers, we multiply the mean by the number of cards:

Sum of the four numbers = Mean * Number of cards

Sum of the four numbers = 10 * 4

Sum of the four numbers = 40

Now, let's find the number on the 4th card. We subtract the sum of the three known numbers from the sum of the four numbers:

Number on the 4th card = Sum of the four numbers - Sum of the three known numbers

Number on the 4th card = 40 - (12 + 6 + 15)

Number on the 4th card = 40 - 33

Number on the 4th card = 7

Therefore, the number on the 4th card is 7.

Answer:

50.24

Step-by-step explanation:

The formula for area is pi · r²

But, because usually people want it simplified instead of a ton of decimal numbers following, pi is rounded to 3.14. And the radius in this case is 4. And the ² means squared, so we have to do 4 · 4 to square it.

So, now our formula is 3.14 · 4 · 4 which equals 50.24

Answer: 4 miles

Step-by-step explanation:

The circumference of a circle can be calculated by using the formula:

= 2πr

where,

π = 22/7

r = radius = 7/11 miles

Therefore, circumference = 2πr

= 2 × 22/7 × 7/11

= 4 miles

Th circumference is 4 miles.

Answer:

f(0) = 31

Step-by-step explanation:

We are given the following function:

[tex]f(x) = \sqrt{7x} + 31[/tex]

f(0).

This is the value of f when [tex]x = 0[/tex]. So

[tex]f(0) = \sqrt{7*0} + 31 = \sqrt{0} + 31 = 0 + 31 = 31[/tex]

Answer:

  BE = 266 2/3

  PE = 233 1/3

Step-by-step explanation:

Part A: The figure has 3 triangles, all similar. In order of shortest-to-longest side lengths, they are ...

  ΔBPE ~ ΔBCG ~ ΔGRE

__

Part B: They can be declared similar by the AA postulate. For BPE and BCG, the angles at B are vertical angles, so are congruent. The angles at C and G are alternate interior angles, so are congruent.

For triangles BPE and GRE, angle E is congruent to itself, The angles at R and P are corresponding angles, so are congruent.

(Remember, GRPC is a parallelogram, so any line in the figure is a transversal crossing parallel lines.)

__

Part C:

From parts A and B, we know ΔBPE ~ ΔBCG. Corresponding sides are proportional:

  BP/BC = BE/BG = PE/CG

  200/300 = BE/400 = PE/350

  BE = (400)(2/3) = 266 2/3

  PE = (350)(2/3) = 233 1/3

Answer: -7/5x

To find slope, you use the formula (THE FORMULA IS IN A PICTURE ATTACHED BELOW)

So by following this formula we would get

-3 - 4               -7

---------      =  -----------

8 - 3                 5

So the slope is -7/5x; BTW most teachers prefer if the answer is still in a fraction not a decimal because it is often easier to graph.

We want to find the slope of the line that passes through the points (3, 4) and (8, -3). We will see that the slope is equal to -7/5

We know that for a line that passes through the points (x₁, y₁) and (x₂, y₂) the slope is given by:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

In this case, we know that the line passes through (3, 4) and (8, -3), then the slope is just:

[tex]a = \frac{-3 - 4}{8 - 3} = \frac{-7}{5}[/tex]

So we can see that the slope of that line is equal to -7/5.
