Width = 2w , Length = w+5 , perimeter = 40
Perimeter of rectangle = 2 (Length + Width)
P= 2 (L + w)
40 = 2 [ (w+5) + (2w) ]
40 = 2 ( 3w+5)
40= 6w +10
6w= 40 – 10
6w= 30
w = 30/6
w = 5
Width = 2w = 2(5) = 10
Length = w + 5 = 5+5 = 10

Seven more than three times 11
Step-by-step explanation:
So, 3 times 11 would give you 33. Then you just add the 7 and it would give you 40!
Seven less than the product of 8 and a number equals 4
Answer:
11/8 or 1 3/8 or 1.375
Step-by-step explanation:
From the information given by the question, we can form an equation:
Let us call the number 'n'
8 × n - 7 = 4
We then move the 7 to the other side, changing it from minus to plus:
8 × n = 4 + 7
So,
8 × n = 11
We divide both sides by 8, to leave n on one side of the equation.
n = 11/8
Therefore, n = 11/8 or 1 3/8 or 1.375
can someone please accurately do this. if you just put anything, i will report and get my points back

(b).
[tex] \frac{7}{2d - 5} = \frac{9}{3d + 4} \\ \\ 7(3d + 4) = 9(2d - 5) \\ 21d + 28 = 18d - 45 \\ 3d = - 73 \\ d = - \frac{73}{3} [/tex]
(c).
[tex] \frac{3}{e + 1} + \frac{1}{2e + 1} = 0 \\ 3(2e + 1) = - (e + 1) \\ 6e + 3 = -(e + 1) \\ 7e = - 4 \\ e = - \frac{4}{7} [/tex]
(d).
[tex] \frac{5}{2f - 5} - \frac{4}{7f + 1} = 0 \\ \\ \frac{5}{2f - 5} = \frac{4}{7f + 1} \\ \\ 5(7f + 1) = 4(2f - 5) \\ 35f + 5 = 8f - 20 \\ 27f = - 25 \\ f = - \frac{25}{27} [/tex]
(d).
Step-by-step explanation:
a)2/5a=4/a-1
By cross multiplication:
5a×4=2(a-1)
20a=2a-2
20a-2a=-2
18a=-2
a=-2/18
a=-1/9
b)7/2d-5=9/3d+4
By cross multiplication:
7(3d+4)=9(2d-5)
21d+28=18d-45
21d-18d=-45-28
3d=-73
d=-73/3
c)3/e+1 + 1/2e+1=0
3/e+1=-1/2e+1
By cross multiplication
3(2e+1)=-1(e+1)
6e+3=-e-1
6e+e=-1-3
7e=-4
e=-4/7
d)5/2f-5-4/7f+1=0
By cross multiplication
5/2f-5=4/7f+1
5(7f+1)=4(2f-5)
35f+5=8f-20
35f-8f=-20-5
27f=-25
f=-25/27

Final grades are often computed using weighted averages. Some college professors use complicated weighted averages. Your college professor tells you he will give a 33%-67% split on grades between tests and homework where whichever average is higher will be the 67%.
What will your final grade be if your homework average is 85 and your test average is 76?
[tex]\\ \sf\longmapsto \dfrac{67}{100}\times 85[/tex]
[tex]\\ \sf\longmapsto 85(0.67)[/tex]
[tex]\\ \sf\longmapsto 56.95[/tex]
33% of 76[tex]\\ \sf\longmapsto \dfrac{33}{100}\times 76[/tex]
[tex]\\ \sf\longmapsto 76(0.33)[/tex]
[tex]\\ \sf\longmapsto 25.08[/tex]
Add both
[tex]\\ \sf\longmapsto 56.95+25.08[/tex]
[tex]\\ \sf\longmapsto 82.03[/tex]
Using weighed averages, it is found that the final grade is was of 82.03.
-------------------
The weighed average, which represents the final grade, is given by the sum of the grades multiplied by it's weights.The higher grade has a weight of 67%.The higher grade was of 85, on homeworks.The lower grade has a weight of 33%.The lower grade was of 76, on the test average.-------------------
Using the data given in the exercise, for the grades, and the weighed average concept, the final grade is:
[tex]G = 85(0.67) + 76(0.33) = 82.03[/tex]
The final grade was of 82.03.

After making several scale drawings Joseph decides on the best placement for a new grillon deck He uses a scale of 2 cm for every 5 in What is the actual area of the space for Joseph's new square inches ?
Answer:
2250
Step-by-step explanation:
The actual areas is 1125 in²
A scale drawing can be described as a drawing of an original image that is reduced by a constant proportion to the original image.
scale of the drawing = original dimensions / dimensions of the scale drawing
The scale used by Joseph = 2 cm : 5 inches
This can be simplified further by dividing by 2
1 cm : 2.5 inches
Based on the image, the dimensions of the grill are 10 cm x 18cm
The length of the actual grill = 18 x 2.5 = 45 inches
The width of the actual grill = 10 x 2.5 = 25 inches
Area of a rectangle = length x width
Area of the actual space for the grill = 25 x 45 = 1125 in²

There are 1024 bytes in a kilobyte. Write an expression that describes the number of bytes in a computer chip with n kilobytes. helpppp
Bytes are used to represent the number of bits in a computer system. There are 1024n bytes in n kilobytes.
Using the following representation:
[tex]KB \to[/tex] Kilobyte
[tex]B \to[/tex] Bytes
1024 bytes in 1 kilobyte is represented as:
[tex]1024B = 1KB[/tex]
Let the number of bytes in n kilobytes be x.
So, we have:
[tex]x = n\ KB[/tex] and
[tex]1024B = 1KB[/tex]
Cross multiply
[tex]x \times 1KB = 1024B \times nKB[/tex]
Divide both sides by KB
[tex]x \times 1 = 1024B \times n[/tex]
[tex]x = 1024n\ B[/tex]
Remove the units for proper representation
[tex]x = 1024n[/tex]
Hence, there are 1024n bytes in n kilobytes

there are 16 marbles in a bag 12 of them are blue and 4 are yellow. what is the probability of picking a blue marble then a yellow marble without replacing the first one
11/20
3/7
1/5
Answer:
1/5
Step-by-step explanation:
the prob that you will pick a blue marble would be 12/16, easy.
then the prob of picking a yellow marble after that would be 4/15 since one marble is already missing. multiply the numerator and denominator of each fraction. so 12 x 4 and 16 x 15 to get 48/240. then divide each by 48 to get 1/5.
the answer is 1/5

What is the equatiqn of the line that passes through the point (-5, 4) and has a
slope of -3/5?
Answer:
y = -3/5x + 1
Step-by-step explanation:
We are given a point and the slope so all we need to solve for is the y-intercept and we can do that by using the slope intercept form formula [ y = mx + b ] where m = slope and b = y-intercept.
4 = -5(-3/5) + b
4 = 3 + b
1 = b
With the information we know, we can input the values into the formula once again.
y = -3/5x + 1

What is the measure of B?
Select the best answer from the choices provided.
A.33°
B. 57
C. 770
D.123
Answer:
B =57
Step-by-step explanation:
The sum of the angles of a triangle is 180
A+B+C = 180
58+B+65 = 180
123+B = 180
B = 180-123
B =57
The angle sum property of a triangle:
The total measure of the three angles of a triangle is 180°∠A + ∠B + ∠C = 180°
∠A = 58° ∠B = 65° ∠C = x⇛58° + 65° + x = 180°
⇛123° + x = 180°
⇛x = 180° - 123°
⇛x = 57°
Option B is the correct answer

For the function f(x) = 3 − 8x, identify the values of f(0), f(1/2), and f(−2).
3; 7; −13
−5; −1; −13
3; −1; 19
−5; 7; 19
Answer:
The answer is 3: -1: 19
Step-by-step explanation:
I. f(x) is output x is input so
If x = 0
f(0) = 3 - 8(0)
f(0) = 3
If x = 1/2
f(1/2) = 3 - 8(1/2)
= 3 - 4
f(1/2) = -1
If x = -2
f(-2) = 3 - 8(-2)
= 3 - (-16)
= 3 + 16
f(-2) = 19
