Answer:
divide 40 by 8cm. it's pretty self explanatory
Step-by-step explanation:
[tex]40cm \div 8cm[/tex]
divided 8 on both sides.
divide 40 from 8 and you're left with 5 cm. the length is 5.
Answer:
length = 12 cm
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2l + 2b ( l is the length and b the breadth )
let x be the length , then
2x + 2(8) = 40
2x + 16 = 40 ( subtract 16 from both sides )
2x = 24 ( divide both sides by 2 )
x = 12
That is the length is 12 cm

Identify the solution(s) of n2 – 5n = 24.
Answer:
n=-3 or n=8
Step-by-step explanation:
Let's solve your equation step-by-step.
n2−5n=24
Step 1: Subtract 24 from both sides.
n2−5n−24=24−24
n2−5n−24=0
Step 2: Factor left side of equation.
(n+3)(n−8)=0
Step 3: Set factors equal to 0.
n+3=0 or n−8=0
n=−3 or n=8
Answer:
n=−3 or n=8

Lucy Liu went shopping at Hollister with her friends together they spent a mean price of $40 on eight sweaters the first step and sweaters cost $50 $55 $30 $35 $39 $40 and $42 how much in dollars does the eighth sweater cost
Answer:he eighth sweater costs $29
Step-by-step explanation:
Let the price of the eighth sweater be re[presented as X
We know that
Mean Price =Total sum of cost of sweater bought/ Number of sweater'
Plugging in our known values we have that
40=$50+ $55+ $30+ $35+ $39+ $40 + $42+X /8
8 X 40 =291 +X
320=291 +X
X =320-291
X=29
Therefore, the eighth sweater costs $29

Answer:
Part A A. 400 sq ft.
Part B A. 509 sq ft
Step-by-step explanation:
Part A
Area of square = side squared
Since all the sides of the square are congruent and the perimeter is 80, then the length of each side is 80/4 = 20
A = 20^2 = 400 sq ft
Part B
C = πd
80 =
80/π = d
r = d/2 = 80/2π = 40/π
A = πr^2 = π(40/π)^2
= 1600π/π^2 = 1600/π = 1600/3.14 = 509 sq ft
6 1/2 chocolate chips and 5/2 cups of flour how many more cups of chocolate chips use than cups of flours
Answer: 4
Step-by-step explanation:
Amount of chocolate chips = 6 1/2
Amount of cups of flour = 5/2
The cups of flour should be changes to a mixed fraction and this will be 5/2 = 2 1/2
The question simply means we should find the difference between the fractions given and this will be:
= 6 1/2 - 2 1/2
= 4

An observer standing on the southern bank of a river sees a tree that is much more than 100 feet downstream on the northern bank of the river. The angle formed by the southern bank and the line from the observer to the tree is 15 ∘. After walking 100 feet downstream, the observer measures the angle formed by the southern bank and the line to the same tree to be 25 ∘. Find the width of the river. (can you show the work please)(also the drawing please)
Answer:
[tex]63\ \text{ft}[/tex]
Step-by-step explanation:
The distances are shown in the figure
[tex]\tan25^{\circ}=\dfrac{p}{b}\\\Rightarrow p=b\tan25^{\circ}[/tex]
[tex]\tan15^{\circ}=\dfrac{p}{b+100}\\\Rightarrow p=b\tan15^{\circ}+100\tan15^{\circ}\\\Rightarrow b\tan25^{\circ}=b\tan15^{\circ}+100\tan15^{\circ}\\\Rightarrow b=\dfrac{100\tan15^{\circ}}{\tan25^{\circ}-\tan15^{\circ}}\\\Rightarrow b=135.08\ \text{ft}[/tex]
[tex]p=b\tan25^{\circ}=135.08\times\tan25^{\circ}\\\Rightarrow p=62.99\approx 63\ \text{ft}[/tex]
The width of the river is [tex]63\ \text{ft}[/tex].

Step-by-step explanation:
When tossing a coin, there are two possibilities, heads or tails, thus one can rule out the first option. When rolling a pyramid-die, then there are four different possibilities, each one with an equally likely chance, and each one's outcome is non-dependant on the outcome of the coin toss. Thus options (B) and (C) can be ruled out. Therefore, option (D) is the only remaining valid option.
Can someone help me with this problem 3(x+1)=11 I need it step by step
Answer:
x = 2.66666667
Step-by-step explanation:
3(x + 1) = 11
We multiply both x and 1 by 3 and get
3x + 3 = 11
Now we subtract 3 from both sides
3x + 3 - 3 = 11 - 3
3x = 8
Now divide both sides by 3
3x/3 = 8/3
x = 2.66666667
