Answer:
d<4 I might not be right but I think this is correct
Step-by-step explanation:
Simplify both sides of the inequality.
−d+12>8
Subtract 12 from both sides.
−d+12−12>8−12
−d>−4
Divide both sides by -1.
[tex]\frac{-d}{-1}[/tex] >[tex]\frac{-4}{-1}[/tex]
d > 4
solve for r
8(-3r-5)>104
Answer:
r<-6
Step-by-step explanation:
8(-3r-5)>104
-24r-40>104
-24r>144
r<144÷-24 (the sign switched because we divided by a negative number)
r<-6

Which is the best estimate for the percent equivalent to 3/8?
A.) 26% B.) 27% C.) 37% D.) 38%
Answer:
C.) 37%
Explanation:
To find this out, turn 3/8 into decimal form, (0.375).
Now, turn each percent into standard form. (Also decimal form)
26% = 0.26, 27% = 0.27, 37% = 0.37, and 38% = 0.38.
The decimal closest to 0.375 is 37%.

write the equation of the parabola in vertex form vertex (0,0) passes through (2,1)
Answer:
[tex]f(x)=\frac{1}{4}x^2[/tex]
Step-by-step explanation:
Recall the vertex form of a quadratic equation:
[tex]f(x)=a(x-h)^2+k[/tex]
Where (h,k) is the vertex.
We are told that the vertex is (0,0). Therefore:
[tex]f(x)=a(x-0)^2+(0)[/tex]
Simplify:
[tex]f(x)=ax^2[/tex]
So, to finish the equation, we need to find a.
We know that a point is (2,1). Thus, substitute 1 for f(x) and 2 for x:
[tex]1=a(2)^2[/tex]
Square:
[tex]1=4a[/tex]
Divide both sides by 4:
[tex]a=\frac{1}{4}[/tex]
So, our a value is 1/4.
And we can thus complete our equation:
[tex]f(x)=\frac{1}{4}x^2[/tex]
And we are done :)

There is a number such that four times the number plus 3 is equal to 19. Find the number.
An equation is formed of two equal expressions. The number is 4.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that there is a number such that four times the number plus 3 is equal to 19.
Let the number be M.
Given that there is a number such that four times the number plus 3 is equal to 19. Therefore, We can write it as,
4M + 3 = 19
Now, we can write,
4M + 3 = 19
Subtract 3 on both sides
4M + 3 - 3 = 19 - 3
4M = 16
Divide both sides by 4,
4/4 M = 16/4
M = 4
Thus, the number is 4.

write an equation to represent the relationship, and find the amount of peanut butter used to make 25 cracker packages. the table is peanut butter (tbsp) 1/2,5/8,3/4,7/8, the bottom is cracker packages 2,2 1/2,3,3 1/2.
We are given 4 points.

[tex](\frac{5}{8},\frac{5}{2})[/tex]
[tex](\frac{3}{4},3)[/tex]

[tex]m=\frac{2.5-2}{0.625-0.5}[/tex]
[tex]m=\frac{0.5}{0.125}[/tex]

A 12-ft ladder leaning against a house makes a 64 degree angle with the ground. Will the ladder reach a window sill that is 10.5 ft up from the base of the house?
Answer:
Yes, it will
Step-by-step explanation:
Given
Length of Ladder = 12 ft
Angle = 64
Required
Determine if it'll reach a height of 10.5ft from the base
See attachment for proper illustration.
From the attachment, we want to determine that x be greater than 10.5
Using sin formula:
[tex]Sin\ 64 = \frac{x}{12}[/tex]
Multiply through by 12
[tex]x = 12 * sin\ 64[/tex]
[tex]x = 12 * 0.8988[/tex]
[tex]x = 10.79[/tex] (Approximated)
Since 10.79 is greater than 10.5, then the ladder will reach the window
sin64 = x/12
x = 12* sin64

Using the statement below, determine the hypothesis and conclusion,
If two integers are even, then their sum is even
Column A
Column B
1.
Hypothesis
a. If two integers are even
2.
Conclusion
b. then their sum is even
c. two integers are even
d. their sum is even
Answer:
Hypothesis
a. If two integers are even
Conclusion
b. then their sum is even
Step-by-step explanation:
We divide the statement into two parts . The first part is true only when the second is also true. The only way we can reject the hypothesis is that the conclusion is false.
In the statement "If two integers are even, then their sum is even" the part "If two integers are even" would be considered true or false on the basis of "then their sum is even" validity. So if the "then their sum is even" (conclusion ) Part is proved then the "If two integers are even" ( hypothesis) is also true.
Hence the hypothesis is
a. If two integers are even
and
Conclusion is
b. then their sum is even
Dr. Gordon has a scale drawing of a building site. The drawing uses the scale 2 in. on the drawing for every 100 ft on the building site. Dr. Gordon marks a 6 in. -by-3.2 in. section of the drawing to show the section she will search. What is the area of the section she will search? Show your work.
Answer:
48000
Step-by-step explanation:
6÷2= 3 in.
3×100= 300 in.
3.2÷2=1.6 in.
1.6×100= 160 in.
A= 160×300= 4800 in.
The required area of the section marked by Dr. Gordon is 48,000 feet².
Given that
Dr. Gordon has a scale drawing of a building site.
The drawing uses the scale 2 in. on the drawing for every 100 ft on the building site.
Dr. Gordon marks a 6 in. -by-3.2 in.
The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Here,
Dr. Gordon marks a 6 in. -by-3.2 in
Length = 6 in
Length= 300 ft (since 2 in = 100 ft)
Width = 3.2 in
Width = 160 ft
Now the required area of the section is = length x width
= 300 * 160
= 48000 feet²
Thus, the required area of the section marked by Dr. Gordon is 48,000 feet².

Use the ogive to approximate (a) the number in the sample, (b) the location of the greatest increase in frequency.
Answer:
Step-by-step explanation:
A). Number of samples given in the ogive = Number of points given n the graph
Number of points plotted on the graph = 16
Therefore, number of samples given = 16
B). Frequency at a point where weight of the pumpkins is 23.5 = 10
Frequency at a point where weight of the pumpkin is 24.5 = 23
Increase in frequency = 23 - 10 = 13
None other points have the increase more than the given points.
Location of the greatest increase in the frequency is between the weights 23.5 - 24.5 pounds.
The number of samples is 16, and the location of greatest increase in frequency is 23.5 to 24.5.
We are provided with an ogive curve. In the x-axis, we have weight in pounds and y-axis represents frequency.
(a).
Now, the number of points on the ogive represents the number of sample.
So, the number of points on the curve is 16 which is also the number of samples.
(b).
The greatest increase in frequency is represented in the range 23.5 to 24.5.
The greatest hike in frequency is about 10.
Therefore, the number of samples is 16, and the location of greatest increase in frequency is 23.5 to 24.5.

Write the equation of the line that goes through the point
(5,8) and is parallel to the x-axis.
Answer:
Y=8
Step-by-step explanation:
If it's a line that is parallel to the x-axis, and you know the equation of a line is y=mx+b, the slope(m) is 0 because the line is not a positive or negative slope (since it's parallel to the x-axis).
So, we now have y=b, where b is the y-intercept. Now, since we know one of its coordinates are (5,8), we know that this line will always stay on y=8 since 8 is the y coordinate of (5,8)
An easy shortcut is if you see the question say parallel to the x-axis, the equation of the line will be y=___; if it says the line is parallel to the y-axis, the equation will be x=___
The sum of three consecutive numbers is 600. What is the least of these three numbers?
Answer:
199
Step-by-step explanation:
So we have three consecutive numbers that totals 600 when added.
Let's let the first number be n.
This means that the next number is (n+1), and the subsequent number is (n+2).
This totals 600. In other words:
[tex](n)+(n+1)+(n+2)=600[/tex]
To solve for the integers, solve for n.
Combine like terms:
[tex]3n+3=600[/tex]
Subtract 3 from both sides:
[tex]3n=597[/tex]
Divide both sides by 3:
[tex]n=199[/tex]
So, the first integer is 199.
So our sequence is: 199, 200, 201.
So, the least of the three is 199.
And we're done!
Answer:
199 200 201
Step-by-step explanation:
199+200+201= 600
