given a number line C=11 and D=13 CD=?can u help me solve this problem?

Step-by-step explanation:

Your slope and your x and y intercept.

x + 2y =7

Divide through by 2, we have:

x/2 + 2y/2 = 7/2

x/2 + y = 7/2

y = 7/2 - x/2

In the form y = mx + c gives.

Where m is the slope.

.: The slope = -1

First, we will start by converting 607,200 feet to miles

1 mile= 5280 foot

607, 200 feet can be changed to mile by dividing it by 5280

That is;

607,200 feet to mile = 607, 200 / 5280 = 115 miles

Hence; speed

= distance over t/

= 115 /1

=115 miles per hour

a) the two angles are supplementary, then:

(3x - 45) + (2x + 25) = 180

(3x + 2x) + (-45 + 25) = 180

5x - 20 = 180

5x = 180 + 20

5x = 200

x = 200/5

x = 40

Then, the measure of the angles are:

3x - 45 = 3*40 - 45 = 75°

2x + 25 = 2*40 + 25 = 105°

b) the two angles are complementary, then:

(2y) + (6y - 30) = 90

(2y + 6y) - 30 = 90

8y = 90 + 30

8y = 120

y = 120/8

y = 15

Then, the measure of the angles are:

2y = 2*15 = 30°

6y - 30 = 6*15 - 30 = 60°

c) the two angles are vertical angles, then they are congruent, that is,

2z + 7 = 5z - 23

7 + 23 = 5z - 2z

30 = 3z

30/3 = z

10 = z

Then, the measure of the angles are:

2z + 7 = 2*10 + 7 = 27°

5z - 23 = 5*10 - 23 = 27°

d) the two angles are alternative exterior angles, then they are congruent, that is,

4x - 5 = 3x + 15

4x - 3x = 15 + 5

x = 20

Then, the measure of the angles are:

4x - 5 = 4*20 - 5 = 75°

3x + 15 = 3*20 + 15 = 75°

The sum of the values is referred to as the operands, arguments, or inputs, while the result is referred to as the value, output, or result. Operations may require less than two inputs or more (including the case of zero input and infinitely many inputs). The answer will be 0.9+0.06+0.004= 0.964

Not all possible values of the domain may be covered by an operation's definition. For instance, it is impossible to square the roots of negative integers or divide by zero in real numbers. An operation's domain of definition, also known as the active domain, is the set of values for which the operation is specified. The set that the values created are contained in is known as the codomain, while the set that the operation really produced is known as the codomain of definition, active codomain, image, or range. For instance, only non-negative numbers are produced by the squaring operation when applied to the real numbers; the set of real numbers is the codomain, but the non-negative numbers are the range.

A scalar can be multiplied by a vector to create another vector (a process known as scalar multiplication), and two vectors can be combined to make a scalar quantity in an inner product operation. An operation may or may not have specific characteristics, such as being idempotent, associative, commutative, or anticommutative.

The total amount that must be repaid will be $26,015.

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

A = P + (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

For $21,500, Norman buys a brand-new vehicle. The loan amount (plus simple interest) must be repaid in full within five years, and the simple interest rate is 4.2%.

The total amount that must be repaid will be given as,

A = $21,500 + ($21,500 x 4.2 x 5)/100

Let,

B = the speed of the boat in still water

S = the speed of the stream

Use the equation for distance.

Rate * Time = Distance

Upstream:

(B-S)6 = 282

Downstream:

(B+S)6 = 402

Simply first:

(B-S)6 = 282

(B-S) = 282/6

B-S=47

(B+S)6 = 402

(B+S) = 402/6

B+S=67

Solve by elimination. Add the two equations.

B-S=47

+ B+S=67

2B = 114

B = 114/2

B = 57 km/hr (the speed of the boat in still water)

Substitute this into either equation and solve for S.

B+S=67

57 + S = 67

S = 67 - 57

S = 10 km/hr (the speed of the stream)

By cross multiplying the given equation, we have

By multiplying the right hand side, we get

Then, by subtracting 6x to both sides, we have

or equivalently,

Since the left hand side is a conjugate binomial, it can be expressed as

Then, we have the equation

The shape of the distribution for the given dot plot is as follows:

The data is skewed right, with fewer values on the right end of the graph. The values at 62 and 89 are possible outliers. The data fits within the average of 60 to 100 beats per minute.

A dot plot shows the number of times that each measure appears in the data-set.

In the context of this problem, we have that from the given dot plot, the measures are as follows:

62, 68, 68, 68, 69, 70, 70, 72, 72, 72, 75, 75, 76, 78, 78, 80, 80, 80, 89, 89.

The mean is the sum of all observations divided by the number of observations, hence, applying it's formula, it is given by:

74.55.

The median is the middle value of the data-set, the value of which 50% of the measures are greater and 50% are less. The data-set in this problem has 20 elements, hence the median is the mean of the 10th and the 11th elements, which are 72 and 75, respectively, hence:

Median = (72 + 75)/2 = 73.5.

The median is less than the median, hence the distribution is skewed to the right, which means that the third option is correct.

Answer:

see explanation

Step-by-step explanation:

(a)

the 2 angles are same- side interior angles and are supplementary.

(c)

since they are supplementary , they sum to 180° , that is

6x + 14 + 10x - 10 = 180

16x + 4 = 180 ( subtract 4 from both sides )

16x = 176 ( divide both sides by 16 )

x = 11

(d)

then

6x + 14 = 6(11) + 14 = 66 + 14 = 80

10x - 10 = 10(11) - 10 = 110 - 10 = 100

note 80 + 100 = 180 ( supplementary angles )

Answer:

|2x - 3| ≥ 1

Step-by-step explanation:

Since the absolute value function is always ≥ 0 we can conclude that                
|2x - 3| ≥ 0 so we can eliminate choices 2 and 4

That leaves two possibilities:
|2x - 3| ≥ 1  and |2x - 3| ≤  1

There are two ways to go about solving this

Pick a point in the given graph on each side of the segment marked in red and see which of the two inequalities both points satisfy

Two points which are on both segments are x = 0 and x = 1

Plug x = 0 into |2x - 3|
|2x - 3| at x = 0
=> | 2 ·0 - 3|  
=> |0 - 3|
=> |-3|
= 3  

Since 3 ≥ 1,  point x = 0 satisfies |2x - 3| ≥ 1

But it does not satisfies |2x - 3| ≤  1 since 3 is not less than or equal to 1

So the correct inequality is |2x - 3| ≥ 1

The input value x when the output value f( x ) = 4 in the function f( x ) = 5x - 7 is 11/5.

A function is simply a relationship that maps one input to one output, each x-value can only have one y-value.

Given the data in the question;

To determine the input value x when the output value f( x ) = 4, replace f( x ) by 4 in the function and solve for x.

f( x ) = 5x - 7

4 = 5x - 7

Collect like terms

4 + 7 = 5x

5x = 11

Divide both sides by 5

5x/5 = 11/5

x = 11/5

Therefore, the input value x is 11/5, this forms an ordered pair of ( 11/5, 4 ).

Length = 4*longer leg

Shorter leg of the base= 1/2 longer leg

We know that Volume = 5832 = 1/2* length* longer leg* shorter leg

Let's call x to the longer leg, the variables are:

length= 4*longer leg= 4x --> x is the longer leg

Shorter leg= 1/2longer leg= 1/2x --> x is the longer leg

Substituting terms, the equation would be:

Multiplying like terms:

Simplifying:

Switching sides:

Isolating x:

Solving the cubic root:

So, x is the value of the longer leg.

Now, we need to find the length, we know that length=4*longer leg

Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant. The equation y = kx represents a proportionate relationship between two quantities y and x that have the same proportionality constant, k. Any relationship that has a constant ratio is said to be proportionate. For instance, the ratio of proportionality is the average number of apples per tree, and the amount of apples in a crop is proportional to the number of trees in the orchard.

By using division, when the restaurant needs at least 736 knives and there are currently 155 knives, if each set on sale contains 12 knives then he minimum number of sets of knives Kaj should buy is 49 sets

The total number of knife that restaurant needs = 736 knives

Number of knives that restaurant has = 155 knives

The number of knife that he want to buy = 736-155

= 581

Number of knives on one set = 12

To find the number of set he wants to buy, we have to use division

Number of sets he wants to buy = 581/12

= 48.41
