Answer:
48 inches.Step-by-step explanation:
Givens
The height of a curb is 4 inches. So, the ramp has a height of 4 inches.The ratio between vertical and horizontal distance of the ramp is 1:12.Accoriding to the given ration, one unit of vertical distance is equivalent to 12 units of horizontal distance. So, the horizontal distance is
[tex]h=12(4 \ in)=48 \ in[/tex]
Therefore, the horizontal distance is 48 inches.
The horizontal distance for a ramp with a 4 inch vertical distance will be 48 inches.
Given,
The height of curb is 4 inches.
We have to calculate the horizontal distance for a ramp with a 4 inch vertical distance.
The ramp from the sidewalk of the street follows the same guidelines as other Ramos, no more than 4.8 degree.
Since The ratio of vertical to horizontal is 1:12, it means for a 1 inch vertical distance the horizontal distance is 12 inches.
So, for 4 inches of vertical distance the horizontal distance will be,
[tex]12\times4=48[/tex] inches.
Hence the required horizontal distance is 48 inches.

Answer:
42
Step-by-step explanation:
im pretty sure I got this right I did it in my head
Answer:
m 5 = 42
Step-by-step explanation:
A line is 180 degrees. m 4 = 138 degrees. 180 - 138 = 42 degrees. this makes m 1 = 42 degrees and m 5 is equal to m 1.

Answer:
As the angles are supplementary, their sum is 180
123 + 3x = 180
3x = 57
x = 19
Answer:
x° = 19°
Step-by-step explanation:
[tex] = > 123 \degree + 3x \degree = 180 \degree \\ \\ = > 3x\degree = 180\degree - 123\degree \\ \\ = > 3x\degree = 57\degree \\ \\ = > x\degree = (\frac{57}{3} )\degree \\ \\ = > x\degree = 19\degree [/tex]

Which best describes the type of association shown in this scatter plot?
•no association
•non-linear association
•positive linear association
•negative linear association
Answer:
Negative linear association/correlation.
Step-by-step explanation:
The type of association that is shown in the scatter plot is negative linear association since it declining at a steady rate with a few outliers. It resembles a line going downwards or sloping downwards.
The best describes the type of association shown in this scatter plot is,
⇒ negative linear association
We have to given that,
A scatter plot is shown in figure.
Since, this scatter plot declining at a steady rate with a few outliers.
And, It resembles a line going downwards or sloping downwards.

The perimeter of a rectangle is 34 units its width is 6.5 Units
Write an equation to determine the length(l) of the rectangle.
Answer: Length=10.5
Step-by-step explanation: P=34 and W=6.5. This can also be known as Perimeter=W+L+W+L=2(W+L). In this case, it would be 34= 2(6.5 +L). 34=13+2L.(The 2L's are crossed out now because they cancel both out)
-2L -2L (There is a line going down at the equal sign.
34+-2L=13 Subtract 34 from both sides and cancel the two 34's out)
-34 -34
-2L=-21 (Divide both sides by -2) (Cancel out the -2's)
/-2 /-2
L = 10.5

Which statement(s) can be interpreted from the equation for a real estate value, V(C)=228,000(1.03)' where V(C) represents the value of the real estate and t represents the time in years?
The equation is an exponential growth equation.
The equation is an exponential decay equation
The equation is neither exponential decay nor exponential growth
$228,000 represents the initial cost of a real estate that appreciates 3% per year over the course of years.
$228,000 represents the initial cost of a real estate that appreciates 30% per year over the course of t years
$228,000 represents the initial cost of a real estate that depreciates 3% per year over the course of t years
$228,000 represents the initial cost of a real estate that depreciates 30% per year over the course of t years
Answer:
The equation is an exponential growth equation.
$228,000 represents the initial cost of a real estate that appreciates 3% per year over the course of years.
Step-by-step explanation:
the correct equation is: V(C)=228,000(1.03)^t
Hi, to answer this question we have to apply an exponential growth equation:
A = P (1 + r) t
Where:
p = initial cost
r = growing rate (decimal form)
t= years
A =cost after t years
Before applying the formula:
1.03 = 1+r
1.03-1 =r
0.03=r
Replacing with the values given:
A = 228,000 (1+ 0.03)^t
r = 0.03
Since r is in decimal form, we have to multiply it by 100
0.03 x 100 = 3% appreciation per year

What is an
equation of the line that passes through the points (-3,8) and (4,1)?
Answer: y= -1x + 5
Step-by-step explanation:
(-3,8) ( 4,1)
8-1= 7
-3-4 = -7
7/-7 = -1 so the slope is -1 so we will use the formula y=mx+b to find the y-intercept
8= -1(-3) + b
8= 3 + b
-3 -3
b= 5 so the y intercept is 5 now we will write the equation like this y= -1x + 5

A quadrilateral has 2 pairs of congruent angles and 4 congruent sides. What is the name of the quadrilateral?
Answer: Rhombus
A rhombus is a quadrilateral with all four sides the same length. If all four angles are the same (all 90 degrees), then the rhombus is more specifically a square. Any rhombus is a parallelogram which is why we have congruent opposite pairs of angles.
Beccas dad told her that she needs to practice piano for two hours this week so far she has practiced 20 minutes on Monday a half an hour on Tuesday and 15 minutes on Wednesday how much longer does she need to practice?
Answer:
Step-by-step explanation:
She needs to practice piano for 2 hours this week:
Lets add the time she played the piano so far:
Monday + Tuesday + Wednesday
Which is
20 + 30 (half an hour) + 15
= 65 minutes
In which 2 hours is equal to 120 minutes
So,
120 - 65 = 55
She needs to practice for 55 more minutes in this week

A clothes shop has some special offers.
T-shirts are buy one get one free and jumpers are 3 for 2.
The normal price of a T-shirt is £3.50 and the normal price of a jumper is £16.
How much does it cost to get 3 jumpers and 8 T-shirts using this offer as appropriate?
Answer:
£142 for 3 jumpers and 8 T-shirts
Step-by-step explanation:
Since the T-shirts cost £3.50 each and they are buy one get one free, when you buy 8 T-shirts you only pay for 4 of them.
£3.50(4) = £140 for the 8 T-shirts
Since you bought 3 jumpers with a buy 3 for £2 sale, the 3 jumpers cost £2.
Add the amount of money all together to find the total cost of the T-shirts and jumpers.
£140 + £2 = £142
