Answer:

The slope -intercept form of the equation is;

y = [tex]\frac{3}{2}[/tex]  x  +   4

Step-by-step explanation:

The slope-intercept form of an equation is;

y = mx + c

where m is the slope and c represent the intercept

To represent the equation given; 3x - 2y = -8 in its slope intercept form, we will follow the steps below:

3x - 2y = -8

subtract 3x from both-side of the equation

3x - 3x -2y  = -3x - 8

-2y = -3x -8

Divide throught the equation by -2

-2y/-2 =-3x/-2  -8/-2

y = [tex]\frac{3}{2}[/tex]  x  +   4

The slope -intercept form of the equation is;

y = [tex]\frac{3}{2}[/tex]  x  +   4

Answer:

1.75

Step-by-step explanation:

Use the distributive property first.

(3.5 x 2.25) (3.5 x X) = 14

7.875 + 3.5x = 14   Now subtract 7.875 from both sides

3.5x = 6.125  Now divide 3.5 by both sides

x = 1.75

The equation 3.5(2.25 + x) = 14 is solved by first distributing 3.5 through the parentheses, then isolating x on one side, yielding a result of x = 1.75.

In this mathematical equation, the first step is to distribute 3.5 to (2.25 + x). The result is 7.875 + 3.5x = 14. We then subtract 7.875 from both sides to isolate the term with x which gives 3.5x = 6.125. Finally, to solve for x, we divide both sides by 3.5. This gives us x = 1.75.

There are 71 dogs in the local animal shelter.

To determine the number of dogs and cats in the shelter, let's denote the number of dogs by D and the number of cats by C. According to the problem statement, there are twice as many cats as dogs, minus three. Mathematically, this is represented as C = 2D - 3. We also know that the combined total of cats and dogs is 210, which can be expressed as C + D = 210. To find the number of dogs, we can solve these two equations simultaneously.

From the first equation, we solve for C in terms of D: C = 2D - 3.

Substitute C into the second equation: (2D - 3) + D = 210.

Combine like terms: 3D - 3 = 210.

Add 3 to both sides of the equation: 3D = 213.

Divide both sides by 3 to solve for D: D = 71.

Therefore, there are 71 dogs in the local animal shelter.

The weight of the guinea pig measured in kilograms is A = 1.130 kg

In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.

The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.

A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.

Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.

Given data ,

Let the measurement of unit be represented as A

Now , the weight of the guinea pig = 1,130 grams

where from the unit conversion

1000 grams = 1 kg

So , weight of the guinea pig measured in kilograms A = 1,130 grams / 1000

On simplifying , we get

The weight of the guinea pig measured in kilograms A = 1.130 kilograms

Therefore , the value of A is 1.13 kg

Hence , the measurement is A = 1.13 kg

The guinea pig weight measured in kilograms is 1.13kgs.

To convert the weight of a guinea pig from grams to kilograms, you need to understand the relationship between these units:

In the metric system, 1 kilogram (kg) is equal to 1,000 grams (g).

Start with the weight of the guinea pig: 1,130 grams.

Use the conversion factor: 1,000 grams = 1 kilogram.

Divide the weight in grams by the conversion factor to find the weight in kilograms.

1,130 grams ÷ 1,000 = 1.13 kilograms.

Answer:

11

Step-by-step explanation:

Let x be how many $10 bills there are.

Let y be how many $100 bills there are

x + y = 30

x = 30 - y

10x + 100y = 2010

10(30 - y) + 100y = 2010

300 - 10y + 100y = 2010

-10y + 100y = 2010 - 300

90y = 1710

y = 1710 / 90

y = 19

x = 30 - 19

As we can see in the graph, the points:

To find a distance between two points or the length of the segment, we use the following formula:

[tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

Because the two points P and Q are located at the same libe y = 8

=> the lenght of PQ = [tex]\sqrt{(6- (-2))^{2} } = \sqrt{8^{2} } = 8\\[/tex]

Because the two points R and Q are located at the same libe x = 6

=>  the length of RQ = [tex]\sqrt{(8-2)^{2} } = \sqrt{6^{2} } = 6\\[/tex]

The lenght of RS is: [tex]\sqrt{(-5-6)^2+(0-2)^2} = \sqrt{-11^{2} +(-2)^{2} }[/tex] = [tex]\sqrt{125} = 11.1[/tex]

The lenght of SP is: [tex]\sqrt{(-5-(-2))^2+(0-8)^2} = \sqrt{-3^{2} +(-8)^{2} } = \sqrt{73}[/tex] = 8.5

Step-by-step explanation:

Answer:

The answer is: 643.4

Step-by-step explanation:

Answer:

a) 984.6080 = 984.61 to 2 decimal places

b) 984.6080 = 984.6 to 4 significant figures

c) 984.6080 = 984.608 to 3 decimal places

d) 984.6080 = 984.61 to the nearest hundredth

Step-by-step explanation:

Answers to the approximation questions above are supplied below.

First, you needs to know approximation processes:

Step 1: Keep the required number of digits in question.

Step 2: Before rounding off the remaining digits, look at the next digit to the required number of accuracy, if it is 5 or more, increase the last digit of the number you're keeping by 1, otherwise leave it as it is and round down to zero all the unwanted digits.

Similarly, there is need know the meaning of each degree of accuracy.

1. Decimal places: These are the number of digits occurring after the decimal point. E.g. a set of figures in 1 decimal place has only one digit after decimal point, i.e. 65.4. In the case of the question above,

a) 984.6080 = 984.61 to 2 decimal places

c) 984.6080 = 984.608 to 3 decimal places

2. Significant figures: Basically, these are nonzero digits in a set of figures. However, when zero is in the middle of nonzero digits, i.e, 3045, such zero is a significant figure. In the question above,

b) 984.6080 = 984.6 to 4 significant figures

3. Hundredth: Under place value system, hundredth of a set of figures is located at two digits after the decimal point. In other words, hundredth is same as two decimal places so the same approach is required for the two. Thus;

d) 984.6080 = 984.61 to the nearest hundredth

You can see that the result for both 2 decimal places and nearest hundredth are the same, that is, 984.6080 = 984.61 to 2 decimal places and to the nearest hundredth respectively.

Therefore, the answers are summarized thus:

a) 984.6080 = 984.61 to 2 decimal places

b) 984.6080 = 984.6 to 4 significant figures

c) 984.6080 = 984.608 to 3 decimal places

d) 984.6080 = 984.61 to the nearest hundredth

Answer:

984.6080

a. 2 decimal places

The parallel lines are a group of straight lines that never intersect with one another. The distance between two parallel is always the same.

The measure of angle 1 is given as ∠1 = 100°.

When two lines intersect each other, the pair of vertically opposite angles are equal.

To find three subtraction equations that show the difference when subtracting a 3-digit number from 920, we need to consider all possible scenarios for the difference.

The smallest possible difference would be a 1-digit number.

To get a 1-digit number, 2-digit number, or a 3-digit number as the result while subtracting a 3-digit number from 920, here are three equations:

• The smallest possible difference would be a 1-digit number. 920 - 911 = 9

• The next possible difference would be a 2-digit number. 920 - 815 = 105

• The largest possible difference would be a 3-digit number. 920 - 100 = 820

In each equation, we started with 920 and subtracted a 3-digit number. Given that the numbers we subtract are less than 920, it becomes possible to get a 1-digit, 2-digit, or 3-digit result.

During its leap, its height h in feet is given by [tex]h= -0.5d^2 + 2d + 3[/tex], where [tex]d[/tex]  is the distance from the base of the stump.

When the stump landed on the ground, h= 0 .

So put h=0 in the given equation , we get
