Quick algebra 1 assignment for 50 points!

Step-by-step explanation:

The polynomial highest degree is 2 so the degree is 2.

The binomial have three terms so it is a trinomial.

The lower bound is 147.5 and the upper bound is 152.5.

Given the weight of an apple 150 g rounded to the nearest 5g.

We have to find lower bound and upper bound.

Lower bound is an element less than or equal to all the elements in a given set.

Upper bound is an element greater than all the elements in a given set.

Lower bound= Number 1- (Number nearest to  which number 1 is rounded)/2

Upper bound=Number 1+(number nearest to which number 1 is rounded)/2

Weight of an apple =150 g

Lower bound=150-5/2

=150-2.5

=147.5

Upper bound=150+5/2

=150+2.5

=152.5

Hence the lower bound is 147.5 and upper bound is 152.5.

Using it's concept, it is found that the approximate perimeter of the front of the garage is:

A. about 36 ft.

The perimeter of a figure is given by the total length of it's boundary.

In this problem, we have that:

[tex]t = \sqrt{3^2 + 5^2} = 5.83[/tex]

Hence the perimeter of the figure is:

P = 10 + 2 x 7 + 2 x 5.83 = 35.66.

Rounding, it is of about 36 ft, hence option A is correct.

Answer:

The volume of the prism increased by a factor of 64.

Step-by-step explanation:

Given that the original prism and the increased prism are similar, we have that the scale factor is:

Area ∝  (length of side) x (length of side)

If the area increases by a factor of 16, each side increases by a scale factor of √16 = 4. Regarding the volume:

Volume ∝ (length of side) x (length of side) x (length of side)

Thus the increase factor for the volume, in this case, is 4 x 4 x 4 = 64.

Properties of an Equilateral Triangle

Given:

Drawing an altitude from vertex A divides the triangle into two 30-60-90 triangles.

A 30-60-90 triangle is special right-angled triangle where:

Therefore, the formula for the sides is: b : b√3 : 2b, where:

As Vertex A has the co-ordinates (0, √3), the side opposite the 60° angle is √3 units.

Using the ratios to find b (shortest side length):

b√3 = √3  ⇒  b = 1

As the altitude divides BC into two equal line segments, and the length of the shortest side of the right triangles is 1 unit, the coordinates of B are C are:

It is given that:

Probability of Households Having cable TV, p₀ = 76% = 0.76

Therefore,

The probability that the Households not having cable TV = 1 - 0.76 = 0.24

Sample size, n = 225 households

sample proportions is less than 82% i.e p = 0.82

Now,

The standard error, SE = [tex]\sqrt{} \frac{0.76(1-0.76)}{225}[/tex]

= 0.02847

Z = [tex]\frac{0.82-0.76}{0.02847}[/tex]

Z = 2.107

therefore, P(sample porportions < 0.82) = P(Z < 2.107)

The Simplified algebraic expression for the statement "n divided by 2 plus five minus n" is given by 5-(n/2).

Algebraic Expression is a mathematical expression involving variables, Numbers, other mathematical quantities, and mathematical operations and combinations of them.

Here given statement is "n divided by 2 plus five minus n"

Now we have to write the above given statement as simplified algebraic expression.

"n divided by 2" is given by = n/2

then "n divided by 2 plus five" is given by = (n/2)+5

there after "n divided by 2 plus five minus n" is given by = (n/2)+5-n

Simplifying the total algebraic expression we get,

(n/2)+5-n = 5-{n-(n/2)} = 5-((2n-n)/2) = 5-(n/2)

The company's profit in fifth month will be $506.25

Profit : The gain in an expenditure, that is when the return is higher than the original amount, then the gained extra amount is called profit.

Example : If someone sell a toy of $10 in $15, then he gained profit & his profit is $(15-10) = $5.

A company earns a profit of $100 the first month it is in business.

Every month after that, the company earns a profit that is 1.5 times the previous month's profit.

In 1st Month,

Profit = $100

In 2nd Month,

Profit = 1.5 times of profit of 1st month

         = 1.5 × $100

         = $150

In 3rd Month,

Profit = 1.5 times of the profit of 2nd month

         = 1.5 × $150

         = $225

In 4th Month,

Profit = 1.5 times of the profit of 3rd month

         = 1.5 × $225

         = $337.5

In 5th Month,

Profit = 1.5 times of the profit of 4th month

         = 1.5 × $337.5

         = $506.25

So, the profit of 5th month = $506.25
