Answer:
Distance between mall and library is 6.32 miles.
Step-by-step explanation:
Coordinates of the door to the library is at (2, 4) and door to the mall is at (8, 4).
Since, distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
By this formula,
Distance between (2, 4) and (8, 4) will be,
Distance = [tex]\sqrt{(8-2)^2+(2-4)^2}[/tex]
= [tex]\sqrt{36+4}[/tex]
= [tex]\sqrt{40}[/tex]
= 6.32 miles

On Monday, a local hamburger shop sold a combined total of 240 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the numbe of hamburgers sold. How many hamburgers were sold on Monday?
Answer:
80
Step-by-step explanation:
because i mutipled
60 hamburgers
240÷2=120
120 for both each
120÷2=60
so i think its 60 hamburgers
correct me if im wrong
Write an equation of the line that passes through (3,3) and (4,8)
Answer:
y=5x-12
Step-by-step explanation:
find the slope first which is (8-3)/(4-3)=5
Then that’s your slope.
after that plug the x into the equation I wrote so that means y=5(3)-12 and you should get the y value which is simple enough if you know how to do it.
Q.2 Find the equation of the straight line passing through the A(-2, -4) and B(1, -7). (3)
Q.3 Find the equation of the straight line passing through (3, 5) and parallel to the line y = 2x+ 3 (2)
Q.4 Find the equation of the straight line passing through (5, 7) and gradient 3
Answer:
See answers below
Step-by-step explanation:
Standard equation of a line is expressed as y = mx+b
m is the slope
b is the y intercept
Given the coordinate points (-2, -4) and B(1, -7)
Slope m = y2-y1/x2-x1
m = -7-(-4)/1-(-2)
m = -7+4/1+2
m = -3/3
m = -1
Get the intercept
Substitute m = -1 and (1, -7) into y = mx+b
-7 = -1(1) + b
-7 = -1 + b
b = -7+1
b = -6
Get thw equation
y = mx+b
y = -x + (-6)
y = -x - 6
Q.3 The equation in point slope form is expressed as y - y0 = m(x-x0)
Given the point (3, 5)
x0 = 3
y0 = 5
Given the equation y = 2x+3
mx = 2x
m = 2
slope = 2
Substitute the slope and the point in the expression
y - 5 = 2(x -3)
y - 5 = 2x - 6
y - 2x = -6 + 5
y - 2x = -1
This gives the required equation
Q.4 The equation in point slope form is expressed as y - y0 = m(x-x0)
Given the point (5, 7)
x0 = 5
y0 = 7
Slope = 3
Substitute the slope and the point in the expression
y - 7 = 3(x -5)
y - 7 = 3x - 15
y - 3x = -15 + 7
y - 3x = -8
This give the required equation
Does anyone know the answer to this?
Answer:
10.5.
Step-by-step explanation:
By similar triangles:
IJ / 21 = 8 /(8+8) = 1/2
IJ / 21 = 1/2
IJ = 1/2 * 21
= 10.5.

2. Ms. Kay did a T-shirt competition to see what shirt to order the 4 graders. There were 48 responses. 75% voted for the black T-shirt.
What is the whole?
What is the percent?
What is the part?
How would you use this formula, part=percent x whole to find the missing information?
Hint: Don't forget to turn
your part into a decimal.
PLEASE show Step by Step in order please! Or take a picture thank you all sm !!!!
Answer:
The whole = 48
The percentage = 78%
The part = 37.44
Step-by-step explanation:
The given parameters are;
The number of responses for the competition = 48 responses
The percentage that voted for the black T-shirt = 75%
The whole = The total number of responses for the competition = 48
The percentage = 78% = The part/(The whole) × 100
The part = The missing information
To find the part, we substitute the values of the whole, and the percentage into the given following equation
The part = The percent × The whole
∴ The part = 78% × 48 = 78/100 × 48 = 37.44
The part = 37.44.
Find the measure of angle A
can you show me how to solve this problem
Answer:
A = 20 degrees
Step-by-step explanation:
Both legs of the triangles are 2x and equal, so we know that the triangle is isoceles. That means both acute angles are equal as well.
In a triangle there are 180 degrees
180 - 140 = 40
40 remainding degrees/ 2 equal angles
A = 20 degrees
Answer:
angle a = 20
Step-by-step explanation:
So like the person above me said
180-140=40
40 divided by 2 is 20

Don't forget to use the formula: V=43πr3
A 392.5 cm3
B 523.3¯ cm3
C 3,140 cm3
D 4,186.6¯ cm3
Answer: The correct answer is B. 523.3...cm^3
Step-by-step explanation:
4/3*pi*r^3 is the formula
first, divide the diameter by 2 to get the radius, now, you will begin solving.
4/3*5^3*3.14
5*5*5=125
4/3*125*3.14
125*3.14=392.5
4/3*392.5

Find the next two terms in the sequence.
40, 10, –20, –50, . . .
A.
60, 80
B.
–80, –110
C.
–70, –100
D.
–70, –90
Answer:
B.
–80, –110
Step-by-step explanation:
-80 and -110
It is an arithmetic sequence. The difference = -30. It is the difference between each number in the sequence: 10-40=-30
-50-30=-80
-80-30 =-110
-80
First Identify the sequence being made here.
10-40 = -30
-20-10 = -30
-50-(-20) = -30
Therefor this pattern is decreasing by a rate of 30 so to continue this, just subtract 30 from -50.
-50-30 = -80
The next term is -80.
Hope I helped!
