Please help.
Answers
Answer:
D. 3
Step-by-step explanation:
Assuming the model represents an equation, the following can be deduced:
On the left side of the equation, the model shows we have 3 "x's", and 6 "1's". Let this represent:
3x + 6
On the right side of the equation, we have 2 "x's" and 9 "1's". Let this represent:
2x + 9.
The model would represent the equation below:
[tex] 3x + 6 = 2x + 9 [/tex]
Solve for x
[tex] 3x + 6 - 2x = 2x + 9 - 2x [/tex] (Subtracting 2x from both sides of the equation)
[tex] x + 6 = 9 [/tex]
[tex] x + 6 - 6 = 9 - 6 [/tex] (subtracting 6 from both sides of the equation)
[tex] x = 3 [/tex]

The length of a rectangle is 3 units greater than its width. If the width is w, what expression gives the perimeter of the rectangle in terms of its width?
Answers
Step-by-step explanation:
let width be "w"
given,length of rectangle is 3 units greater than its width
length= w+ 3
perimeter of rectangle= 2( l+ b)
= 2[( w+3)+ w]
= 2(w to the power of 2 + 3w)
= 2w to the power of 2 + 6w
is the answer
The perimeter of the rectangle is 4w+6 units
What is the perimeter of rectangle?The perimeter of a rectangle is the sum of its four sides. Perimeter of Rectangle = 2 (Length + Width) units.
According to the question
Width of rectangle = w
Length of rectangle = w+3
Perimeter of Rectangle = 2 (Length + Width)
= 2( w+3 +w)
= 2(2w+3)
= 4w+6 units
Hence, The perimeter of the rectangle is 4w+6 units .

In 2016 49% of all degrees granted were bachelors degrees if 1,920,718 students earned bachelors degrees how many total degrees were granted that year
Answers
Answer:
3919832.65306Step-by-step explanation:
This problem is focused on percentages.
Now given that 49% of a number is 1,920,718
we can say let the number be x
so 49% of x= 1,920,718
now expressing this problem mathematically we have
(49/100)*x= 1,920,718
0.49x= 1,920,718
divide both sides by 0.49 we have
x= 1,920,718/0.49
x= 3919832.65306
Therefore the total that were granted degree that year was 3919832.65306

Part II: Approximate how many times greater the sun's diameter is than planet Earth's.
Answers
Answer:
see below
Step-by-step explanation:
given;
Planet Earth has an approximate diameter of 1.2742 x 10¹⁰ millimeters.
The sun has a diameter of 1.391 x 10⁶ kilometers.
find:
Part I:
Given that for every one kilometer there are 1,000,000 millimeters, which unit of measurement should be used to best represent the lengths of the sun and Earth's diameters?
Part II:
Approximate how many times greater the sun's diameter is than planet Earth's.
-------------------------------------------------------------------------------------------------------
part I:
the best measurement to represent the lengths of the sun and Earth's diameters is kilometers.
= planet dia. = 1.2742 x 10¹⁰ mm x 1 km = 12,742 km
1,000,000 mm
= sun dia. = 1.391 x 10⁶ km = 1,391 x 10³ km = 1,391,000 km
part II:
the approximate scale dia ratio of earth to sun is = sun dia. over earth's dia.
= 1,391,000 km
12,742 km
= 109.17 times
therefore,
109.17 times greater the sun's diameter is than planet Earth's.
Put these numbers in order from least to greatest.

How much money will he make if he mows 9 lawns? _________(blank 2) Question 1 options: Blank # 1 Blank # 2
Answers
Answer:
[tex]20\ lawns = \$240[/tex]
[tex]9 \ lawns = \$108[/tex]
See Attachment for Graph
Step-by-step explanation:
Given
[tex]1\ lawn = \$12[/tex]
Solving (a): Number of lawns in $240
[tex]1\ lawn = \$12[/tex]
Multiply both sides by 20
[tex]20 * 1\ lawn = \$12 * 20[/tex]
[tex]20\ lawns = \$240[/tex]
Solving (b): Cost of mowing 9 lawns
[tex]1\ lawn = \$12[/tex]
Multiply both sides by 9
[tex]9 * 1\ lawn = \$12 * 9[/tex]
[tex]9 \ lawns = \$108[/tex]
To create a graph, we need to generate a formula;
If
[tex]1\ lawn = \$12[/tex]
[tex]2\ lawn = \$24[/tex]
[tex]3\ lawns = \$36[/tex]
[tex]x\ lawns = \$12x[/tex]
So:
The graph formula is
[tex]y = 12x[/tex]

quotient of twice a number and 6 is 42
Answers
Answer:
[tex]n = 126[/tex]
Step-by-step explanation:
First let's model this into an equation.
Twice a number is [tex]2n[/tex], and that divided by 6 is [tex]\frac{2n}{6}[/tex]. That's equal to 42, so we have [tex]\frac{2n}{6} = 42[/tex].
Now we can simplify this equation by isolating n on one side of the equation.
Multiply both sides by 6:
[tex]\frac{2n}{6} \cdot 6 = 42\cdot 6\\\\2n = 252[/tex]
Divide both sides by 2:
[tex]2n \div 2 = 252\div 2\\\\n = 126[/tex]

For the directed line segment whose endpoints are B(0, 0) and C(12, 24), find the point whose coordinates are 3/4 from B to C.
Answers
Answer:
(9, 18)
Step-by-step explanation:
If point P is 3/4 of the distance from B to C, it means that ...
BP/BC = 3/4
(P - B) = 3/4(C - B) . . . . . . multiply by BC = (C-B)
P = B + 3/4C -3/4B . . . . . add B
P = (1/4)B +(3/4)C = (B +3C)/4
P = ((0, 0) +3(12, 24))/4 = (36, 72)/4 = (9, 18)
The desired point is (9, 18).
__
As we showed, since B = (0, 0), the point is 3/4 of the coordinates of C.

What is the distance between two points?It is the measure of distance between the two points and is known as length. The length is measured in meters generally.
Let one point be (x, y) and another point be (h, k).
Then the distance between the points will be
D² = (x - h)² + (y - k)²
The endpoints of line segment XY are given below.
X(-9, 2) and Y(5, -4)
The distance between the endpoints of line segment XY will be given as,
D² = (x - h)² + (y - k)²
D² = (5 + 9)² + (-4 - 2)²
D² = (14)² + (-6)²
D² = 196 + 36
D² = 232
D = √232
D = 15.2 units
The distance between the endpoints of line section XY will be 15.2 units.
