Find L if A=LW, A=55 m2, and W=11 m.
Answer:44
Step-by-step explanation:subtract 55-11 which would equal L
Answer:
If you are multiplying L*W the answer would be 5 because w=11 ok and we don't know what L is but we know what A is and a=55 so you have to think what do we multiply 11 by to get 55 weel it's 5 so that's how we would know it's 5 IF you were multiplying. now if you just adding L+W that answer would be 44 because 55-11=44

DeShawn and Mike each improved their yards by planting rose bushes and geraniums. They
bought their supplies from the same store. DeShawn spent $13 on 1 rose bush and 4 geraniums.
Mike spent $56 on 10 rose bushes and 3 geraniums. Find the cost of one rose bush and the cost of one geranium.
Answer:
Cost of 1 rose bush = x = $5
Cost of 1 geraniums = y = $2
Step-by-step explanation:
DeShawn and Mike each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same store.
Let us represent:
Cost of 1 rose bush = x
Cost of 1 geraniums = y
DeShawn spent $13 on 1 rose bush and 4 geraniums.
x + 4y = 13..... Equation 1
x = 13 - 4y
Mike spent $56 on 10 rose bushes and 3 geraniums.
10x + 3y = 56....... Equation 2
We substitute 13 - 4y for x in Equation 2
10(13 - 4y) + 3y = 56
130 - 40y + 3y = 56
Collect like terms
- 40y + 3y = 56 - 130
-37y = -74
y = -74/37
y = $2
Solving for x
x = 13 - 4y
x = _13 - 4 × $2
x = $13 - $8
x = $5
Therefore,
Cost of 1 rose bush = x = $5
Cost of 1 geraniums = y = $2

a. How far is the spot on the beach from the parking lot?
b. How far will he have to walk from the parking lot to get to the refreshment stand?
Show work please.
The altitude of the right triangle is the geometric mean of the 2 parts of the side it separates.
a. The answer would be sqrt(18*32)=24
The question to the second question can be answered by using the Pythagorean theorem.
32^2+24^2=1600=40^2
b. The answer would be sqrt40^2=40
The beach, the parking lot and the refreshment stand are illustrations of similar triangles.
The distance between the spot and the parking lot is 24 mThe distance between the refreshment stand and the parking lot is 40 m(a) The distance between the spot and the parking lot
Represent this distance with d.
So, the equivalent ratio is:
[tex]\mathbf{32:d = d : 18}[/tex]
Express as fractions
[tex]\mathbf{\frac {32}d = \frac{d}{ 18}}[/tex]
Cross multiply
[tex]\mathbf{d \times d = 32 \times 18}[/tex]
[tex]\mathbf{d^2 = 576}[/tex]
Take square roots
[tex]\mathbf{d = 24}[/tex]
Hence, the distance between the spot and the parking lot is 24 m
(b) The distance between the refreshment stand and the parking lot
Represent this distance with d.
Using Pythagoras theorem we have:
[tex]\mathbf{d^2 = 32^2 + 24^2}[/tex]
[tex]\mathbf{d^2 = 1600}[/tex]
Take square roots
[tex]\mathbf{d = 40}[/tex]
Hence, the distance between the refreshment stand and the parking lot is 40 m

Magdala is modeling 2.12÷4 how to cheeks change the place value blocks so she can make 4 equal shares
Answer and explanation:
If Magdala is trying to divide 2.12 by 4 then she would definitely need to change the place value of the dividend(2.12) and the divisor(4). In other words, both numbers need to be whole numbers.
To make 2.12 a whole number, we shift the decimal point two places to the right of the decimal point to get 212. We do same for 4 to get 400, since both numbers have to have their place values adjusted equally.
We divide 212 by 400 to get 0.53
Therefore 2.12 divided by 4= 0.53
find p(-1) p(1) if p(x) = X2+1
Answer:
p(- 1) = 2 and p(1) = 2
Step-by-step explanation:
Substitute x = - 1 and x = 1 into p(x), that is
p(- 1) = (- 1)² + 1 = 1 + 1 = 2
p(1) = 1² + 1 = 1 + 1 = 2

Multiplying by 0.5 with original price.
Here,
A shop owner increases some prices by 50%.
We have to find another method to find same condition.
What is the percentage?
A relative value indicating hundredth parts of any quantity is called the percentage.
Now,
A shop owner increases some prices by 50%.
Let the original price is x.
Then, The increase value = x * 50% = x * 50/100 = 0.5x
Hence, To find the increase value we have to multiply by 0.5 with original price.

the mean temperature for the first 4 days in January was - 4 degrees the mean temperature for the first 5 days in January was - 6
degrees what was the temperature on the 5th day
Answer: The temperature on the 5th day is -14 degrees.
Step-by-step explanation:
If we have a set of N values:
{x₁, x₂, x₃, ..., xₙ}
The mean value of this set is:
M = (x₁ + x₂ + ... + xₙ)/N
Now, we know that the mean temperature for the first 4 days of January is -4°
Then if the temperatures for the first four days are {T₁, T₂, T₃, T₄}
We have:
M₄ = (T₁ + T₂ + T₃ + T₄)/4 = -4°
Where we can replace (T₁ + T₂ + T₃ + T₄) by K
Then:
K/4 = -4°
K = -4°*4 = -16°
Is the sum of the temperatures for the first four days.
Now when we consider the first 5 days, the mean is -6°, and let's define T₅ as the temperature of the fifth day, then we get:
M₅ = -6° = (T₁ + T₂ + T₃ + T₄ + T₅)/5
And we know that:
(T₁ + T₂ + T₃ + T₄) = K = -16°
We can replace that in the above equation to get:
M₅ = (-16° + T₅)/5 = -6°
Now we can solve this for T₅
(-16° + T₅) = 5*(-6°) = -30°
T₅ = -30° + 16° = -14°
T₅ = -14°
The temperature on the 5th day is -14 degrees.
