Answer:
4.0
Step-by-step explanation:
Look at the decimal place next to the tenths place. It has a 2 in its place. The rule for rounding is that any number 4 or lower is rounded down. Any number 5 or above is rounded up. The number is 2, which is below 4, so we round down. The tenths place would stay the same because it can't get any smaller. Therefore, 4.028 is rounded down to 4.0

On a certain map, 3 centimetres represents 25 kilometres. How many kilometres does 1 1/2 decimeters represent?
Answer:
125 kilometres does 1 1/2 decimetres represent
Step-by-step explanation:
Given
3 cm = 25 KM (Representative)
we have to find value of 1 1/2 decimetre
1 1/2 decimetre = (1*2+1)/2 decimetre = 3/2 decimetre
we know
1 decimetres = 10 cm
3/2 decimetres = 3/2 *10 cm = 15 cm
thus, we have to find 15 cm on the 3 cm = 25 KM map.
3 cm = 25 KM
1 cm = 25/3 KM
15 cm = 15*25/3 KM = 125 KM
Thus,
125 kilometres does 1 1/2 decimetres represent
what is the slope of a line that passes through the points ( 3,7) and(12,7)?
Answer:
The slope is 0.
Step-by-step explanation:
To find the slope, we can do (7 - 7) / (12 - 3) = 0 / 9 = 0. This makes sense because if we look at the points, they both have the same y-coordinate, so we know that as x increases / decreases, y never changes. Because y never changes, the slope is 0.
Answer:
m=0
Step-by-step explanation:
To find slope, it is y2-y1/x2-x1
Therefore, x1=3, x2=12, y1=7 and y2=8
Plugging those variables in,
(7-7)/(12-3)=
7-7=0
12-3=9
0/9=0
Therefore, slope of the line that passes through points (3,7) and (12,7) is 0
Determine whether the following statement is true or false. Explain your reasoning. Jordan says that when solving the equation 4b+3=11, the best first step is to apply the Division Property of Equality.
.
A. The statement is false. Since there is a coefficient on the variable, the Multiplication Property of Equality should be used first.
.
B. The statement is true. The Division Property of Equality should always be the first property of equality used when solving linear equations.
.
C. The statement is false. The Subtraction Property of Equality should be used first to remove the constant term before dividing.
.
D. The statement is true. Since there is a coefficient on the variable, the Division Property of Equality must be used first.
Answer:
The correct option is;
C. The statement is false. The Subtraction Property of Equality should be used first to remove the constant term before dividing
Step-by-step explanation:
In other to solve the equation 4·b + 3 = 11, we have;
By the subtraction property of equality, we have;
Firstly we subtract 3 from both sides gives;
4·b + 3 - 3= 11 - 3
Next we apply the division property of equality, we have;
Both sides of an equation remain equal when we divide both sides of the equation by the same, non-number,
Dividing both sides by 4, gives;
4·b/4 = 8/4
b = 8/4 = 2
The solution to the equation, 4·b + 3 = 11 is b = 2.

Kendrick is using a compass and straightedge to copy angle M the figure shows the portion of the construction that he has already completed where should Kendrick place the center of the compass to do the next step of the construction
Answer:
The next step of the construction is;
Place the compass at point N and adjust the width to the point where the arc crosses the other side leg of the angle
Step-by-step explanation:
The steps to copy an angle are;
1) Mark the point C of the vertex of the new angle
2) Draw a ray from C in the desired direction
3) With the compass placed at M of the original angle, draw an arc that crosses both sides of the original angle. Mark the crossing points N and O
4) With the same compass width from the arc drawn in the above step, draw a similar arc that crosses the ray from C at point D
5) Place the compass at point N and adjust the width to point O, the point where the arc crosses the other side of the angle
6) While the adjusted compass width is held to remain the same, place the compass at point D and draw an arc to cross the previous arc drawn from C and label the intersection point E
7) With the straight edge, draw a ray FC that passes through E to point C to complete the copied angle.

4 days x days
Using cross products

Answer:
[tex]\Large \boxed{\mathrm{27. \ 14 \ days}} \\ \\ \Large \boxed{\mathrm{29. \ 4 \frac{1}{6} \ feet}}[/tex]
Step-by-step explanation:
(27)
We can apply ratios to solve for the problem.
Let x be the missing value.
[tex]\displaystyle \frac{152}{4} =\frac{532}{x}[/tex]
Cross multiply.
152 × x = 532 × 4
152x = 2128
Divide both sides by 152.
x = 14
(29)
We can apply ratios to solve for the problem.
Let x be the missing value.
[tex]\displaystyle \frac{1}{6\frac{1}{4} } =\frac{\frac{2}{3} }{x}[/tex]
Cross multiply.
1 × x = 6 1/4 × 2/3
x = 6 1/4 × 2/3
Convert mixed fraction to improper fraction.
x = 25/4 × 2/3
x = 50/12
Simplify.
x = 25/6 or 4 1/6

Ursula says that the flagpole and sidewalk can be
used to model two lines. Which term best describes
the sidewalk and the flagpole?
Answer:
Skew lines
Step-by-step explanation:
Skew lines are two straight lines in three dimensional space that are neither parallel nor do they intersect Examples of skew lines are the front sidewalk and a line that goes along one of the top edges of the house, or lines that connecting opposite edges of a regular tetrahedron
Other examples of skew lines can be found in non co-planar non parallel, parts of a bridge.

Molly earns a rebate each month on her movie tickets and books. She earns $0.25 for each movie ticket and $2 for each book. Last month molly purchased 4 movie tickets and earned $17. How many books did molly purchase last month?
Answer:
8 books
Step-by-step explanation:
Earning for each ticket is $0.25 and for each book is $2
If total earning for 4 tickets and x books is $17, then the equation is:
0.25*4 + 2x = 171 + 2x = 172x = 16x = 16/2x = 8So Molly purchased 8 books
9.48 as a mixed number in simplist form
Answer:
9 12/25.Step-by-step explanation:
9.48 as a mixed number in simplest form:
948/100
948/100= 948 ÷ 4/100 ÷ 4
948/100= 948 ÷ 4/100 ÷ 4= 237/25
948/100= 948 ÷ 4/100 ÷ 4= 237/25= 9 12/25
9 12/25 is the mixed number.

A linear equation is represented as:

So, we have:
[tex]\mathbf{y = \frac 23 x + b}[/tex]
[tex]\mathbf{(x,y)= (0,0)}[/tex] represents the y-intercept (i.e. b = 0).
