Answer:
Length of the rectangular lot = 60 meters
Width of the rectangular lot = 30 meters
Step-by-step explanation:
Let the width of the rectangular lot be x meters.
So, Length of the same = 2x metres.
[tex]A(rectangular \:lot) = (2x)(x)[/tex]
[tex]\implies A(rectangular \:lot) = 2x^2[/tex]
When length is increasEd by 40 m and width by 6 m. Then....
New length = [tex](2x + 40) \:m[/tex]
New width =[tex](x + 6) \:m[/tex]
According to the question:
[tex](2x + 40)(x + 6) = 2(2x^2)[/tex]
[tex]\implies 2x(x + 6) + 40(x + 6) - 4x^2=0[/tex]
[tex]\implies 2x^2+12x + 40x + 240 - 4x^2=0[/tex]
[tex]\implies 2x^2- 4x^2+12x + 40x + 240 =0[/tex]
[tex]\implies -2x^2+52x + 240 =0[/tex]
[tex]\implies 2(x^2-26x - 120) =0[/tex]
[tex]\implies x^2-26x - 120=0[/tex]
[tex]\implies x^2-30x+4x - 120=0[/tex]
[tex]\implies x(x-30)+4(x - 30)=0[/tex]
[tex]\implies (x-30)(x+4)=0[/tex]
[tex]\implies x-30=0,\: x+4=0[/tex]
[tex]\implies x=30,\: x=-4[/tex]
Since, x represents the side length, so its value can't be negative.
[tex]\implies x=30[/tex]
[tex]\implies 2x=2(30)=60[/tex]
Thus,
Length of the rectangular lot = 60 meters
Width of the rectangular lot = 30 meters
2/3 of a hippos life is spent underwater, the rest of their life out of water is separated into grazing, sleeping and socialising in the ratio 4:7:1. The average life of a hippo is 45 years, how long will it spend doing each of these activities?
Answer:
Under water is 2/3×45= 30yrs
So rest is 1/3
1/3 is divide in 12 parts
1/3÷12=1/36
Grazing is 4/36×45= 5yrs
Sleeping is 7/36×45=8.75yrs
Socialising is 1/36×45=1.25yrs

Jack draws a pattern of 2 cm wide strips on the wall in the following order: a red strip, a blue strip, an orange strip, a pink strip, and then he repeats the colors in the same order. How long is Jack's pattern if the first and last stripes he painted were red, and he painted six red strips in total?
Answer:
His pattern is 42cm long.
Step-by-step explanation:
Each repetition of the pattern is 8 cm (4 colors time 2cm each)
If the last color is red and he painted 6 red strips in total, then he repeated the pattern 5 times and ended on an extra red strip.
So 8cm times 5 repetitions equals 40, plus 2cm for the extra red strip.

16 - 2t = 3/2 t + 9 .
Answer:
t=2
Step-by-step explanation:
Start by subtracting 9 from both sides. You'll get 7-2t=3/2t. I made 3/2 a mixed number, so 1 1/2. You should have 7-2t=1 1/2t. Add 2t to both sides, because the 2t is negative. You should have 7=3 1/2t. Last step is to divide 3 1/2 into both sides. 7 divided by 3 1/2 is equal to 2, so t=2

What is 7/8 divided by 6/8
Simplify your answer.
Hey there!
7/8÷6/8=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
7/8×8/6=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
7×8/8×6=56/48
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 56 and 48 using
GCF(56,48) = 8
56÷8/48÷8=76
The fraction
7/6
is the same as
7÷6
Convert to a mixed number using
long division for 7 ÷ 6 = 1R1, so
7/6= [tex]1 \frac{1}{6} [/tex]
Therefore:
7/8÷6/8= 1 1/6
Let's do
[tex]\\ \bf\hookrightarrow \dfrac{7}{8}\div \dfrac{6}{8}[/tex]
[tex]\\ \bf\hookrightarrow \dfrac{7}{8}\times \dfrac{8}{6}[/tex]
[tex]\\ \bf\hookrightarrow \dfrac{7}{8}\times \dfrac{4}{3}[/tex]
Cancel 4 and 8[tex]\\ \bf\hookrightarrow \dfrac{7}{2}\times \dfrac{1}{3}[/tex]
[tex]\\ \bf\hookrightarrow \dfrac{7}{6}[/tex]

7x-2=-9
Plz asap can y’all explain step by step plzzz it’s for a homework
Answer:
Step 1: Add 2 to both sides.
7x−2+2=−9+2
7x=−7
Step 2: Divide both sides by 7.
7x/7 = -7/7
Answer: x=−1
Answer:
x=-1
Step-by-step explanation:
7x-2=-9 (Given)
7x=-7 (Add 2 on both sides to eliminate he -2 on the left side)
x=-1 (Divide both sides with 7 to eliminate the 7 in 7x)
Answer: x=-1

Complex solid composed of rectangular prisms in an L shape. The bottom face is labeled with a length of 14.9 ft. The height of the shorter side of the L shape is labeled 5 ft. The height between the shorter side and taller side of the L shape is labeled 9.8 ft. The length of the of the taller section of the L shape is labeled 6.1 ft and the width is labeled 4.9 ft.
The new surface area of the figure that is 1 / 3 of the original size is 198.79 ft².
What is surface area?The surface area of a solid is a measure of the total area occupied by the surface of an object.
Therefore, the surface area of the figure can be calculated as follows:
surface area = (5 × 6.1) + (5 × 10) + (9.8 × 6.1) + (4.9 × 6.1) + (10 × 5) + (14.8 × 4.9) + (10 × 5) + (14.8 × 4.9) + (14.8 × 6.1) + (14.9 × 6.1)
surface area = 30.5 + 50 + 59.78 + 29.89 + 50 + 72.52 + 50 + 72.52 + 90.28 + 90.89
original surface area = 596.38 ft²
Therefore,
New surface area = 1 / 3 × 596.38
New surface area = 198.793333333
New surface area = 198.79 ft²

factor the polynomial 4x^4-20x^2-3x^2+15 by grouping. what is the resulting expression?
Answer:
(4x^2-3)(x^2-5)
Step-by-step explanation:
We are going to group the first two and last two terms and find the GCF of each set.
4x^4-20x^2-3x^2+15
(4x^4-20x^2)(-3x^2+15)
4x^2(x^2-5)-3(x^2-5)
Then we group the GFCs together and the rest
(4x^2-3)(x^2-5)

Enter the first 4 terms of the sequence defined by the given rule. Assume that the domain of each function is the set of whole numbers greater than 0.
f(n)=n3-7
The first 4 terms of the sequence are______,______,______,_______.
Given:
The given rule is
[tex]f(n)=n^3-7[/tex]
Domain of the function is the set of whole numbers greater than 0.
To find:
The first 4 terms of the sequence.
Solution:
We have,
[tex]f(n)=n^3-7[/tex]
Domain of the function is the set of whole numbers greater than 0. So, the domain for first four terms of the sequence are 1, 2, 3 and 4 respectively.
For n=1,
[tex]f(1)=(1)^3-7[/tex]
[tex]f(1)=1-7[/tex]
[tex]f(1)=-6[/tex]
For n=2,
[tex]f(2)=(2)^3-7[/tex]
[tex]f(2)=8-7[/tex]
[tex]f(2)=1[/tex]
For n=3,
[tex]f(3)=(3)^3-7[/tex]
[tex]f(3)=27-7[/tex]
[tex]f(3)=20[/tex]
For n=4,
[tex]f(4)=(4)^3-7[/tex]
[tex]f(4)=64-7[/tex]
[tex]f(4)=57[/tex]
Therefore, the first 4 terms of the sequence are -6, 1, 20, 57 respectively.
