Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

$78

Step-by-step explanation:

Here we have to find total distance first then find amount of gasoline used based on distance traveled by car in one gallon.

_____________________________________________

Given

time = 12 hours

speed = 64 miles per hour

we know distance = speed * time

distance = 12*64 = 768 miles.

Thus, car ran 768 miles.

given that car gets an average of 32 miles per gallon.

It means in one gallon gasoline car travels 32 miles.

let the gallons used be x

in 1 gallon gasoline car travels 32 miles.

in 1*x gallon gasoline car travels 32*x miles = 32x

Thus, 32x should be equal to 768 miles as car traveled that much only

32x = 768 miles

x = 768/32 = 24

Thus, gallons of gasoline used is 24.

Cost of 1 gallon gasoline = $3.25

since, gallons found is 24, we multiply lHS and RHS by 24

Cost of 1 *24= 24 gallon gasoline = $3.25*24 = $78

Thus,

cost of 24 gallon is $78 which will be the gasoline cost for the trip.

Answer:

$5304

Step-by-step explanation:

One load of soil is 12 tons.

Multiply 34 with 12: 34 x 12 = 408 tonnes in all.

Next, multiply the cost per tonne with the amount of tonnes:

408 x 13 = 5304

$5304 is the total cost.

Answer:

He can build 20 houses. He will have 5 left over.

Step-by-step explanation:

8 x 20 = 160

165 (total blocks) - 160 (highest possibility) = 5 (not enough to build a house, which is why they are left over)

Answer:

z=12/9 or 4/3 or 1 1/3

Step-by-step explanation:

1/3 needs to have a denominator of 9 so 3/9 because 3x3=9 and you have to multiply the numerator by 3 also

z-4/9-3/9=5/9

add -4/9 and -3/9 because you add two negative numbers

new equation

z-7/9=5/9

add 7/9 to 5/9

z=12/9 or 4/3 or 1 1/3

Answer:

[tex]R = 9.63\ units[/tex]

Step-by-step explanation:

Given

[tex]AB = BC = 17[/tex]

[tex]AC = 16[/tex]

Required

Determine the circumradius, R

The circumradius is calculated as follows;

[tex]R = \frac{AB * BC * AC}{\sqrt{(AB + BC + AC)(AB + BC - AC)(AB + AC - BC)(AC + BC - AB)}}[/tex]

Substitute the values of AB, BC and AC

[tex]R = \frac{17 * 17 * 16}{\sqrt{(17 + 17 + 16)(17 + 17 - 16)(17 + 16 - 17)(16 + 17 - 17)}}[/tex]

Evaluate the denominator

[tex]R = \frac{17 * 17 * 16}{\sqrt{(50)(18)(16)(16)}}[/tex]

[tex]R = \frac{4624}{\sqrt{230400}}[/tex]

Take square root of 230400

[tex]R = \frac{4624}{480}[/tex]

[tex]R = 9.63\ units[/tex] (Approximated)

Hence, the circumradius is 9.63

Answer:

289/30

Step-by-step explanation:

Let the circumcenter be point O. We start by drawing line median BM. Since AB = BC, median BM is perpendicular to side AC.

Therefore, BM is part of the perpendicular bisector of AC and thus, must pass through point O.

We have AM = 8, so the Pythagorean Theorem applied to triangle ABM gives us BM = 15.

Let OA = x, our circumradius. Since O is equidistant from A and B, we have OB = x as well.

Therefore,

OM = BM - BO = 15 - x.

From right triangle OAM, we have (OA)^2 = (OM)^2 + (AM)^2.

Solving for x, we have 30x = 225 + 64.

So, x = 289/30.

Answer:

Lines

Step-by-step explanation:

In both linear and vertical pairs share at least one line.

Hope This Helps :)

All linear pairs and vertical pairs share the same supplementary angle.

Linear pairs and vertical pairs are both types of angle pairs formed by intersecting lines or by the intersection of a line and a transversal.

1. Linear Pairs: A linear pair consists of two adjacent angles formed by two intersecting lines. The two angles in a linear pair are always supplementary, meaning their measures add up to 180 degrees. In other words, if one angle in a linear pair measures x degrees, then the other angle will measure (180 - x) degrees.

2. Vertical Pairs: Vertical angles are formed by the intersection of two lines. They are opposite angles that share a common vertex but are formed by different pairs of intersecting lines. Vertical angles are congruent, meaning they have the same measure. If one vertical angle measures x degrees, then the other vertical angle formed by the same pair of intersecting lines will also measure x degrees.

Therefore, both linear pairs and vertical pairs share the same property of having angles with equal measures. In the case of linear pairs, the angles are supplementary (their measures add up to 180 degrees), while in vertical pairs, the angles are congruent (they have the same measure).

Answer  x= - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:  -12x + 12 = 18 move constant to the right hand side and change its sign ( its + 12 :0)

-12x = 18- 12 caculate 18-12

-12x = 6

then divide both sides then you will get -1/2

Answer:

Angle 1 is 147 degrees

Step-by-step explanation:

When two angles form a linear pair, then we have the intersection of two lines

So what this mean is that both angles lie on a straight line and the sum of both angles is 180.

Let the angle 2 be x

We are told that angle 1 is 18 degrees less than 5 times the measure of angle 2;

What we are saying here is that; angle 1 = 5x - 18

So let’s add both together to give 180

angle 1 + angle 2 = 180

x + 5x -18 = 180

6x = 180+ 18

6x = 198

x = 198/6

x = 33 degrees

But angle 1 is 5x -18 = 5(33) -18 = 165 -18 = 147 degrees

g  = x - c + y

First, let's add c to both sides.

g + c = x + y

Now, let's subtract y from both sides.

g + c - y = x

x = 2.

===================================================

Explanation:

It is a function because it passes the vertical line test. We cannot draw a single vertical line through more than one point on the red curve. Any x input leads to exactly one and only one y output.

A similar test is the horizontal line test. We cannot draw a single horizontal line through more than one point on the red curve, so this red curve passes the horizontal line test. Each y is only paired with one x value only. This helps set up an inverse function.

-----------

In short:

If the curve passes the vertical line test, then we have a function

If the curve passes the horizontal line test, then it is one-to-one.
