Step-by-step explanation:
whats 7 over 4 =35 over m in solving proportions NO LINKS PLZ
Hey there!
7/4 = 35/m
CROSS MULTIPLY BOTH of your NUMBERS
7(m) = 4(35)
7(m) = 7m
4(35) = 140
NEW EQUATION: 7m = 140
DIVIDE 7 to BOTH SIDES
7m/7 = 140/7
CANCEL out: 7/7 because that gives you 1
KEEP: 140/7 because that gives you the value of m
140/7 = m
Solve above and you have the answer of m
140/7 = 20
Therefore, the value of m = 20
Answer: m = 20
Good luck on your assignment and enjoy your day!

What is the solution set to the equation 4x2 – 16 = 0?
Answer:
2
Step-by-step explanation:
add 16 to zero
4x2=16
Divide 4x by 2 and 16 by two
4x=8
divide 8 by 4
x=2
Answer:
x = ± 2
Step-by-step explanation:
Given
4x² - 16 = 0 ( add 16 to both sides )
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take the square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2
solutions are x = - 2, x = 2

y varies directly with x. If y = 15 when x = -18, find y when x = 1.6.
Answer:
y= -1.328
Step-by-step explanation:
15= k*-18
15=k*-18 (divide both sides by -18)
It doesn't go in evenly so you are left with a negative decimal
k= -0.83
Now find y
y= -0.83(1.6)= -1.328

A teacher has two boxes. The first box has a height of 15 in., a width of 6 in., and a length of 8 in. The second box’s dimensions are twice that of the first box. How many times larger is the surface area of the second box than the first box?
A. The surface area of the second box is 6 times larger.
B. The surface area of the second box is 4 times larger.
C. The surface area of the second box is 3 times larger.
D. The surface area of the second box is 2 times larger.
Answer:
The correct option is B: the surface area of the second box is 4 times larger.
Step-by-step explanation:
The surface area of the first box is given by:
[tex] SA_{1} = 2l_{1}h_{1} + 2w_{1}h_{1} + 2l_{1}w_{1} [/tex]
Where:
l₁: is the length = 8 in
h₁: is the height = 15 in
w₁: is the width = 6 in
[tex] SA_{1} = 2*8*15 + 2*6*15 + 2*8*6 = 516 in^{2} [/tex]
The second box's dimensions are:
l₂ = 2*8 in = 16 in
h₂ = 2*15 in = 30 in
w₂ = 2*6 in = 12 in
Hence, the surface area of the second box is:
[tex]SA_{2} = 2*2l_{1}*2h_{1} + 2*2w_{1}*2h_{1} + 2*2l_{1}*2w_{1} = 4(2l_{1}h_{1} + 2w_{1}h_{1} + 2l_{1}w_{1}) = 4*SA_{1} = 4*516 in^{2} = 2064 in^{2}[/tex]
Therefore, the correct option is B: the surface area of the second box is 4 times larger.
I hope it helps you!
The ratio of length to width in a rectangle is 3 to 1. If the perimeter of the rectangle is 120 feet, what is the length of the rectangle?
Answer:
a = length
b = height(width)
a=3b
2(a+b)=120
2(b+3b)=2(4b)=8b
8b=120
b=15
a=45
length is 45 feet
width is 15 feet

Answer:
x = 17
y = 8
QPR = 35º
QRP = 60º
Step-by-step explanation:
2x + 1 = x + 18
Subtract x from both sides
x + 1 = 18
Subtract 1 from both sides
x = 17
QPR = 2x + 1
QPR = 2(17) + 1
QPR = 35º
-------------------------------
8y - 4 = 4y + 28
Subtract 4y from both sides
4y - 4 = 28
Add 4 to both sides
4y = 32
Divide both sides by 4
y = 8
QPR = 8y - 4
QRP = 8(8) - 4
QRP = 60º

In the figure below, mLJK = 37° and mKLJ = 69°.
Answer:
C
Step-by-step explanation:
ΔJKL consist of 3 angles: ∠mLJK, ∠mKLJ and ∠mJKL
We are given the measures of ∠mLJK and ∠mKLJ
In order to find ∠mJKH we must find the missing angle in the triangle
Remember that angles in a triangle add up to equal 180
If we are given two angles we can find the missing angle by subtracting the measures of the known angles from 180
so ∠mJKL = 180 - 37 - 69
180 - 37 - 69 = 74
Hence, ∠mJKL = 74°
Now to find ∠mJKH
Angles ∠K, ∠mJKH and ∠mJKL appear to be formed on a straight line
Angles formed on a straight line add up to equal to 180
So ∠K + ∠mJKH + ∠mJKL = 180 ( note that this is the equation that will be used to solve for ∠mJKH )
∠K is a right angle, indicated by the little square.
Right angles have a measure of 90° so ∠K = 90
We have also calculated the measure of ∠mJKH = ( 74° )
That being said we plug in the given values into the equation created earlier and solve for ∠mJKH
We would have 90 + ∠mJKH + 74 = 180
Now we solve for ∠mJKH
step 1: combine like terms
90 + 74 = 164
now we have 164 + ∠mJKH = 180
step 2 subtract 164 from each side
180 - 164 = 16
164 - 164 cancels out
we're left with ∠mJKH = 16
Hence the answer is C

Answer:
11. parallelogram, rectangle
12. parallelogram, rhombus
13. parallelogram, square
For parallelogram:
In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
for rectangle:
A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). Other names for quadrilateral include quadrangle (in analogy to triangle), tetragon (in analogy to pentagon and hexagon), and 4-gon (in analogy to n-gons for arbitrary values of n).
for rhombus:
In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a diamond.
for Square:
·There are four methods that you can use to prove that a quadrilateral is a square. In the last three of these methods, you first have to prove (or be given) that the quadrilateral is a rectangle, rhombus, or both:
·If a quadrilateral has four congruent sides and four right angles, then it’s a square (reverse of the square definition).
·If two consecutive sides of a rectangle are congruent, then it’s a square (neither the reverse of the definition nor the converse of a property).
·If a rhombus contains a right angle, then it’s a square (neither the reverse of the definition nor the converse of a property).
·If a quadrilateral is both a rectangle and a rhombus, then it’s a square (neither the reverse of the definition nor the converse of a property).
