The value of the equation 7a = 28 is a = 4

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

7a = 28

On simplifying the equation , we get

Divide by 7 on  both sides of the equation , we get

a = 28 / 7

a = 4

Therefore , the value of a is 4

Hence , The value of the equation 7a = 28 is a = 4

The conditions are not met by the extreme outliers, hence we are unable to draw inferences based on the statistical output presented above.

So, option e is correct.

The null hypothesis, often known as H₀, is the assertion that there is no difference between two sets of data or variables under analysis, or that there is no relationship between them. Because there is no underlying causative relationship, the null hypothesis holds that any experimentally detected difference is merely the result of chance; therefore, the name "null."

We can create a z-test hypothesis by assuming that the amount of rain produced by thunderheads follows a distribution that is nearly normal:

300 acre feet is the null hypothesis for the average quantity of rain that thunderheads produce on their own without fertilizing the clouds.

Alternative Hypothesis: The amount of rain that thunderheads often produce by seeding the clouds is greater than 300 acre feet.

This test has a right tail.

(a) There are 10 vertical rise per step.

(b) There are 58 steps needed to climb from road level to the 2nd floor.

What is angle of elevation?

The angle of elevation is the angle created between the line of sight and the horizontal. The angle created is an angle of elevation if the line of sight is upward from the horizontal line.

(a) First to find the vertical rise per step.

x = 13 x tan(37)

x = 9.80

x ≈ 10

Hence, there are 10 vertical rise per step.

(b) Now to find number of steps needed to climb from road level to the 2nd floor.

The total elevation = 24 + 24 = 48 feet

Vertical rise of each step = 10

To convert 48 feet into inches

⇒  48 x 12 = 576 inches

So, the number of steps = 576 / 10 = 57.6 ≈ 58

Hence, there are 58 steps needed to climb from road level to the 2nd floor.

Company A costs less for mileage than Company B, which can be represented by the inequality  0   ≤ m < 85 .

The parameters for the two companies are as follows:

For Company A, the initial cost is $55.

For Company B, the initial cost is $97.50.

The extra cost per mile is 20 cents.

Let us depict the overall fee for company A by C₁ and the total charge for company B by C₂, and we will obtain;

C₁ = 55 + 0.70 × m

C₂ =  97.50 + 0.20 × m

Where "m" stands for the amount of miles driven.

Therefore, the cost of Company A and Company B are the same or equal when have the following relation;

C₁ = C₂

Now we will solve the equation to find the value of m.

∴ 55 + 0.70 × m = 97.50 + 0.20 × m

0.70 × m - 0.20 × m = 97.50 - 55

0.5 × m = 42.5

m = 85

m = 85 miles is the number of miles driven for which both companies will charge the same amount.

As a result, given that Company A's initial fee is smaller than Company B's initial fee, we have;

As a result, Company A charges less than Company B for 0 miles m 85 miles.

Therefore the inequality to represent is given by: 0   ≤ m < 85

Answer:

1)  x=16

2) x=15

3) x=10

Step-by-step explanation:

1)  Since the triangles are similar and the ratio of the sides is 1 : 2, 1/2=(3x-4)/(10x-72). Cross multiplying, we get 6x-8=10x-72.

10x-72=6x-8 |+72

10x=6x+64 |-6x

4x=64  |/4

x=16

2) Angles HGJ and KLJ are corresponding (they are equal angles).

So, 5x-2=9x-62.

5x-2=9x-62  |+62

5x+60=9x  |-5x

60=4x |/4

x=15

3) If KM is a perpendicular bisector, KJ=KL.

So, 4x+9=11x-61.

4x+9=11x-61 |-4x

9=7x-61   |+61

70=7x  |/7

x=10

By using the fact that all the triangles are equilateral, we will see that AB = 32 units.

Here we have a figure made of equilateral triangles. Remember that all the sides of an equilateral triangle have the same measure.

Now we can see that FE = 16, then with that we can conclude that each segment of two consecutive vertices also measures 16 unints.

Now, we can write AB as:

AB = AD + DB

And we know that:

AD = 16 units

DB = 16 units.

Then:

AB = 16 + 16 = 32 units

That is the length of segment AB.

What are volume and area?

The area is the volume a flat, two-dimensional item occupies in a plane. The space occupied by a three-dimensional object is referred to as its volume. Area is measured in square units. Volume is measured in cubic units.

The volume formula is what.

The basic formula for volume is length, breadth, and height, as opposed to length, width, and height for the area of a rectangular shape. The calculation is unaffected by how you refer to the various dimensions; for instance, you can use "depth" instead of "height."

Given that :

Cube 1 has volume = 343 cubic feet

Volume = [tex]a^{3}[/tex]

[tex]a^{3}[/tex] = 343

a = 7

Cube 2 has volume = 64 cubic feet

As per the question:

The path of the projectile is modeled using the equation :

h(t) = -16t²+48t+190  (equation 2)

h(t) = height after t time.

comparing equation 1 and equation 2, we get

a = -16 and b = 48
