Answer:(15, 100)
Step-by-step explanation:
first find the coordinates of the point above (3, 20)
you just look at the x axis and where the point is in this case x would be 6 and then you find y which would be 40
so the coordinate would be (6, 40)
now subtract (6, 40) by (3, 20)
6-3= 3
40- 20= 20
you get the first coordnites which is what you add (12,80) to
12 +3= 15
80+ 20= 100
you get the coordinates (15, 100)

What is the equation of the line that has a slope of –4 and passes through the point (2, 3)?
Answer:
y=-4x+11
Step-by-step explanation:
We can use the point-slope form of a line to solve this, which is
y - y₁ = m (x - x₁), where (x₁ , y₁) is a point and m is the slope.
We have:
y - 3 = -4(x - 2)
y - 3 = -4x + 8
y = -4x + 11
Hope this helps!

A second-grade student is 4 feet tall. Her teacher is 5 2/3 feet tall.
How many times as tall as the student is the teacher?
What fraction of the teacher’s height is the student’s height?
Can anyone help with this please?
Answer:
1. 17/12
2. 12/17
Step-by-step explanation:
The teacher is 1.42 times as tall as the student and the required fraction is given by 17/12
What is a ratio?The quantitative relation between two amounts shows the number of times one value contains or is contained within the other. for example-"the ratio of computers to students is now 2 to 1"
Given here; Height of the student = 4 ft. and height of teacher =5²/₃
Ratio of the height of the teacher and student is
= 5+2/3 / 4 ( 5²/₃=5+2/3 , property of mixed fractions)
= 17/3 × 1/4
=17/12
=1.4166
Thus we can say that the height of teacher is 1.42 times as tall as the student.
Also as given above the teacher's height is 17/12 the students height.
Hence, The teacher is 1.42 times as tall as the student and the required fraction is given by 17/12

2. Why was Susan Weiss' work not
considered important?
Answer:
she was a woman.
is the relation a function?
please help.
Answer:
Yes
Step-by-step explanation:
A function has one input (x-value) per output (y-value).
In other words, a relation that does not repeat any x values is a function.
{(3,4) , (5,0) , (2,4) , (-5,-5)}
The domain of the relation is:
{-5,2,3,5}
Since none of the numbers repeat in the domain, the relation is a function.
For which values of x is the function
Y=x+4/(x+5)(x+11)
not defined? Select all that apply.
-4
5
-5
11
Answer:
x = - 5, x = - 11
Step-by-step explanation:
Given
y = [tex]\frac{x+4}{(x+5)(x+11)}[/tex]
The denominator cannot be zero as this would make y undefined.
Equating the denominator to zero and solving gives the values that x cannot be, that is
(x + 5)(x + 11) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x + 11 = 0 ⇒ x = - 11
Thus
x = - 11 and x = - 5 are excluded values.
4. Francisco says, "36 is 75% of 48." Is Francisco correct or incorrect?
Show your reasoning using a Tape Diagram."
Answer:
see below
Step-by-step explanation:
Is means equal and of means multiply
36 = 75% * 48
36 = .75* 48
36 = 3/4* 48
36 =36
Using the tape diagram
Divide 48 into 4 pieces
12 12 12 12
Then circle 3 of them
12 +12 + 12
36
Answer:
Correct
Step-by-step explanation:
75% of 48
75/100 × 48
3/4 × 48
36
Divide the tape of length 48 units into 4 parts, 3 parts add up to 36

What is the length of Line segment A J if Line segment A B is parallel to lines segment J K?
8 in.
8.75 in.
10.25 in.
14 in.
Answer:
8.75 in.
Step-by-step explanation:
See attachment for the figure.
As you can see, ∆ HBA & ∆HKJ are similar,
HB/HA = HK/HJ
3/5.25 = 8/HJ
3HJ/5.25 = 8
3HJ = 42
HJ = 14 in.
AJ = 14 - 5.25
AJ = 8.75 in.
Therefore, the length of Line segment AJ is 8.75 in.
Answer:
(B) 8.75

Write the equation of a circle with a center at (-2,-10) and a radius of 1.2.
A) (x + 2)2 + (y + 10)2 =1.2
B) (x - 2)2 + (y - 10)2 = 1.2
C) (x + 2)2 + (y + 10)2 = 1.44
D) (x + 2)2 + (y + 10)2 = 14.4
Answer:
The correct option is the letter "C", [tex](x + 2)^2 + (y + 10)^2 = 1.44[/tex].
Step-by-step explanation:
The standard form for a circle's equation has the following structure:
[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]
Where [tex](x_c,y_c)[/tex] are the coordinates of the center of the circle and [tex]r[/tex] is the radius. Applying the data from the problem we have:
[tex](x - x_c)^2 + (y - y_c)^2 = r^2\\\[[x - (-2)]^2+ [y - (-10)]^2 = (1.2)^2\\(x + 2)^2 + (y + 10)^2 = 1.44[/tex]
Therefore the correct answer is the letter "C", [tex](x + 2)^2 + (y + 10)^2 = 1.44[/tex].
The side length of a square is 5.25 inches. What is its area? What is its perimeter? Be sure to show your work for credit and don't forget to label units!
Answer:
Step-by-step explanation:
area of a square is just L^2 or one of the sides squared
and the perimeter is 4L
that means
Area = 5.25^2
= 27.5625 in^2
Perimeter = 4 * 5.25
= 21 in
A cone with a radius of 7ft and a height of 12ft is filled with wet sand. you took that sand and built a pyramid with a base of 4ft by 5ft how tall would the resulting pyramid be?
Answer:
95.36 ft
Step-by-step explanation:
Volume of a Cone[tex]=\frac{1}{3}\pi r^2 h[/tex]
Radius=7 ft, Height=12 ft
Therefore the volume of sand in the cone
[tex]=\frac{1}{3}\pi *7^2*12\\=615.7522$ ft^2[/tex]
If the sand was used to build as pyramid with a base of 4ft by 5ft.
Volume of a Pyramid[tex]=\frac{1}{3}*$Base Area* Height[/tex]
[tex]615.7522=\frac{1}{3}*(4*5)* Height\\615.7522=\dfrac{20}{3}* Height\\$Multiply both sides by \dfrac{3}{20}\\$Height =615.7522*\dfrac{3}{20}\\\\$Height of the pyramid=95.36 ft[/tex]
Find the 23rd term of this sequence -25,-15,-5,5....
Answer:
195
Step-by-step explanation:
To find the 23rd term of this sequence, we can use the arithmetic sequence formula [tex]a_{n} =a_{1} +(n-1)d[/tex] where,
[tex]a_{n}[/tex] = [tex]n^{th}[/tex] term
[tex]a_{1}[/tex] = first term
[tex]n[/tex] = term position
[tex]d[/tex] = common difference
[tex]a_{23}=-25+(23-1)10[/tex]
[tex]a_{23} =195[/tex]
