Answer:
a. 12.5
Step-by-step explanation:
Scale factor of ∆LMN to ∆XYZ = 2:5
To find length of side ZX, set the ratio of the corresponding sides of interest equal to the scale factor.
Thus:
ZX corresponds to NL = 5
NL:ZX = 2:5
5:ZX = 2:5
5/ZX = 2/5
Cross multiply
5*5 = ZX*2
25 = ZX*2
Divide both sides by 2
25/2 = ZX
12.5 = ZX
ZX = 12.5

10(2^×) + 7(3^×) = 6^× + 70
Answer:
x = 2.81 and 2.096
Step-by-step explanation:
Given the expression
10(2^x) + 7(3^x) = 6^x + 70
This can also be expressed as;
10(2^x) + 7(3^x) = (2*3)^x + 70
10(2^x) + 7(3^x) = 2^x*3^x + 70
Let a = 2^x and b = 3^x
10a + 7b = ab + 70
10a + 7b - ab = 70
10a-ab + 7b - 70 = 0
a(10-b)+7(b-10) = 0
a(10-b)-7(10-b) = 0
a-7 = 0 and 10-b = 0
a = 7 and b = 10
Since a = 2^x
7 = 2^x
log 7 = log2^x
log7 = xlog2
x = log7/log2
x = 2.81
Similarly
10 = 3^x
log 10 = log 3^x
log 10 = xlog3
x = log 10/log 3
x = 1/0.4771
x = 2.096
Hence the values of x that satisfies the equation are 2.81 and 2.096

How many more students went to summer camp than traveled abroad?
Answer:
63
Step-by-step explanation:
A checkerboard used in a board game is a square where each side is 16 inches (in.)
long. Find the units for the perimeter of the checkerboard.
We have side of square checkerboard, and to find perimeter we have a formula :
[tex] \large \underline{\boxed{\bf{Perimeter_{(square)} = 4 \times side}}}[/tex]
As, side of square checkerboard is 16 inches.
[tex] \sf : \implies Perimeter_{(checkerboard)} = 4 \times 16 \: inches[/tex]
[tex] \sf : \implies Perimeter_{(checkerboard)} = 64 \: inches[/tex]
Hence, perimeter of checkerboard is 64 inches.

What's the circumference of a
circle with a radius of 7 feet?
Use 3.14 for n.
C = [?] feet
Step-by-step explanation:
Radius (r) = 7 feet
circumference (c) = ?
We know
C =2 πr
= 2 * 3.14 * 7
= 43.96 feet
Hope it will help :)
Answer: 43.96
==================================================
Work Shown:
C = 2*pi*r
C = 2*pi*7
C = 2*7*pi
C = 14pi ............. exact circumference in terms of pi
C = 14*3.14
C = 43.96
This value is approximate because pi = 3.14 is approximate.
Note: the circumference is the same as the perimeter of the circle. It's the distance around the circle's edge.
What is the total distance between ( 8,6 )and (8 -2 ) on a coordinate plane HELP MEEEE
Answer:
Distance = 8
Step-by-step explanation:
The length of the line between (8,6) and (8,-2) is 8.
The distance between (8, 6) and (8, -2) is 8 units.
Distance between the two points:Distance between two points is the length of the line segment that connects two given points.
Formula for the distance between two points:[tex]d = \sqrt{(x_{2}-x_{1}) ^{2} +(y_{2} -y_{1}) ^{2} }[/tex]
According to the given question
We have two points
(8, 6) and (8, -2)
Let,
[tex](x_{1} ,y_{1} ) = (8,6)[/tex]
and, [tex](x_{2},y_{2}) =(8,-6)[/tex]
Therefore,
The total distance between (8, 6) and (8, -2)
[tex]=\sqrt{(8-8)^{2}+(-2-6)^{2} }[/tex]
[tex]=\sqrt{0+(-8)^{2} }[/tex]
[tex]=\sqrt{64}[/tex]
[tex]=8[/tex] unit
Hence, the distance between (8, 6) and (8, -2) is 8 units.

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 23% of your total grade, each major test is worth 21.5%, and the final exam is worth 34%. Compute the weighted average for the following scores: 67 on the lab, 69 on the first major test, 85 on the second major test, and 63 on the final exam.
Answer:
The weighted average is of 69.94.
Step-by-step explanation:
Weighted average:
The weighed average is found multiplying each grade by its respective weight.
The grades, and weights are:
67 on the lab, with a weight of 23% = 0.23
69 on the first major test, with a weight is 21.5% = 0.215
85 on the second major test, with a weight is 21.5% = 0.215.
63 on the final exam, with a weight of 34% = 0.34.
Weighted average:
[tex]A = 0.23*67 + 0.215*69 + 0.215*85 + 0.34*63 = 69.94[/tex]
The weighted average is of 69.94.

Write an equation passing through the point (-3,-2) parallel to y=3x+1 in standard form. Please show your work. You can type in your steps or work it out on a separate sheet of paper and email me a picture.
Answer:
y = 3x + 7
Step-by-step explanation:
Parallel lines have the same slope, so you can write the equation y = 3x + b and you have to figure out what b is.
plug in x = -3 and y = -2 into the equation y = 3x + b:
-2 = 3 * -3 + b
-2 = -9 + b
7 = b
So the equation is y = 3x + 7
