Answer:

8.2 units (nearest tenth)

Step-by-step explanation:

Distance between two points

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where (x₁, y₁) and (x₂, y₂) are the two points.

Given points:

Substitute the given points into the distance formula and solve for d:

[tex]\implies d=\sqrt{(4-6)^2+(-1-7)^2}[/tex]

[tex]\implies d=\sqrt{(-2)^2+(-8)^2}[/tex]

[tex]\implies d=\sqrt{4+64}[/tex]

[tex]\implies d=\sqrt{68}[/tex]

[tex]\implies d=8.2 \; \sf (nearest\;tenth)[/tex]

Therefore, the distance between the two given points is 8.2 units to the nearest tenth.

The number of miles that is covered is  1458 miles.

The term gas mileage refers to the distance that have been covered by the car using a given volume of gas. It is common that the unit that is used to measure the volume of the gas is the US gallon.

We have been told that;

420 miles could be covered by the use of 20 gallons

1 mile can be covered by the use of 1 mile  * 20 gallons/ 420 miles

= 0.048 gallons

If 1 mile requires  0.048 gallons

x miles requires 70 gallons

According to the normal distribution table, the probability that their mean blood pressure will be less than 127 is 99.38%.

Given :

Blood pressure readings are normally distributed with a mean of 125 and a standard deviation of 8.

The formula of z-score is used to determine the probability that their mean blood pressure will be less than 127. The formula of z score is given by:

[tex]z = \frac{\frac{x - m}{\alpha } }{\sqrt{n} }[/tex]

Now, substitute the values of known terms in the above equation.

[tex]z = \frac{\frac{127 - 125}{8} }{\sqrt{100} }[/tex]

[tex]z = \frac{\frac{2}{8} }{10} }[/tex]

Further, simplify the above expression.

z = 2.5

P(z < 2.5) = 0.9938

So, the probability is 99.38%.

Therefore, according to the normal distribution table, the probability that their mean blood pressure will be less than 127 is 99.38%.

This postulate tells us that when we put two angles side by side with a ray touching the ray of the other angle, we are creating a new angle which is the addition of the two, and whose measure is the addition of the measures of the two angles we are contacting via a common ray.

By dividing $180 in the ratio of 2:3:4, we get 40,60 and 80

Solution

2 + 3 + 4 = 9

180 ÷ 9 = 20

Hence, we get the quotient of 20.

20 × 2 = 40

20 × 3 = 60

20 × 4 = 80

It is to be noted that, given the dilation factor stated above, the coordinates of S' is (4, 3).

The mathematical Definition of Dilation is given as a transformation that allows you to resize an object. Dilation is a technique for making items bigger or smaller. This transformation yields a picture that is identical to the original shape. However, there is a size discrepancy in the form.

The computation for the above result is given as follows:

Given that RST has vertices R(0,0), S(6, 3), and T(3, -3); and

The image R'S'T' is the image of RST after a dilation with center (0,0) with scale factor 2/3,

We must determine the coordinates of point S'.

The coordinates of S' can be determined by multiplying both the x and y - coordinates of the point S with the scale factor 2/3.

Let us look at x- coordinate with point S and multiply it with the scale factor of 2/3.

we have: 6 x 2/3 = 4

Hence, x- coordinate for S' = 4

Redo for Y

3 x 2/3 = 3

Hence, y- coordinate for S' = 3

Hence the coordinates of S' is (4, 3).

Hence having applied the principle of dilation, the coordinates of S' are (4,3)

The mistake was made in Step 3.

The table is a linear function and the equation is y = -3(x - 1) + 4

From the question, we have the pairs to be

From the above representations, we can see that:

As the values of x increase by +2, the values of y constantly increase by -6

This means that the table has a constant rate

By the definition of a linear function, the table represents a linear function

In (a), we have

x = +2

y = -6

The slope is calculated as

Slope = y/x

So, we have

Slope = -6/2

Evaluate

Slope = -3

The equation is then calculated as

Y = Slope * (X - x) + y

Where

(x, y) = (1, 4)

So, we have

y = -3(x - 1) + 4

Hence, the linear function is y = -3(x - 1) + 4

What are a few properties of a triangle considering its angles?
A triangle's outer angle is the sum of its internal angles' two opposite sides.
The sum of two linear angles is supplementary.

Given, the three angles of the triangle are measured as (5x - 3)°,
(4x - 2)° and j°.
Also, the exterior angle of the triangle is (10x - 20)°.
Following the literature established above, considering that a triangle's outer angle is the product of its internal angles' two opposite sides, we have: (5x - 3) + (4x - 2) = 10x - 20 ⇒ 9x - 5 = 10x - 20 ⇒ 10x - 9x = 20 - 5
⇒ x = 15 --(i)
Again, since the sum of two linear angles is supplementary, we have using (i):
j + (10x - 20) = 180 ⇒ j + 150 - 20 = 180 ⇒ j = 10°
Therefore, the measure of the value of ∠j is 10°.

The unknown angle in the triangle is as follows;

The angle H can be found using the exterior angle theorem.

The exterior angle theorem states that the measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angles.

In other words,  an exterior angle of a triangle is equal to the sum of the two opposite interior angles.

Hence,

∠DFG = ∠G + ∠H

∠DFG = 14x + 1

∠G  = 89°

∠H = 5x - 7

14x + 1 = 89 + 5x - 7

14x + 1 = 89 - 7 + 5x

14x - 5x = 89 - 7 - 1

9x = 81

divide both sides by 9

x = 81 / 9

x = 9

Therefore,

∠H = 5(9) - 7 = 45 - 7 = 38 degrees.

Corresponding angles:

Corresponding angle means the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line.

Given,

Two electricity poles are built standing parallel to each other, as shown below. The measure of angle 1 is 81°.

Here we need to find the measure of the angle 2.

We know that,

If the lines are parallel if they are always the same distance apart (called "equidistant"), and will never meet.

And as per the definition of corresponding angles, we know that, if any two lines are said to be parallel if the Corresponding angles so formed are equal.

Then the measure of the angle 2 is 81° because angle 1 and 2 are parallel.

The measurement of the largest square tiles she can use is 6 feet.

Finding all common factors between two numbers and choosing the biggest one yields the highest common factor (HCF). For instance, the numbers 8 and 12 share the elements 1, 2, and 4. Four is the greatest common factor.

Steps for calculating HCF:

Step 1: Write each integer as the sum of its prime factors in step one.

Step 2: List the shared factors between the two numbers.

Step 3: The HCF is the sum of all the common prime factors ( use the lower power of each common factor)

Given,

Measurement of the rectangular floor:

length = 150 feet

breadth = 132 feet

The measurement of the largest square can be calculated by finding the HCF of 132 and 150.

132 = 2*2*3*11

150 = 2*3*5*5

So, HCF (132, 150) = 2*3 = 6.
