If each quadrilateral below is a rectangle, find the missing measures.
Answers
Answer:
GF = 11
GE = 28
DF = 28
HF = 14
DG = √(663)
Step-by-step explanation:
We have that for a rectangle;
1) The opposite sides are equal
Therefore, GF = DE = 11
2) The diagonals of a rectangle are equal and they bisect each other
Therefore;
HE = HF = GH = 14
∴ HF = 14
HE = 14
GE = GH + HE = 14 + 14 = 28
GE = 28
DF = GE = 28
DF = 28
3) The sides of a rectangle are perpendicular
Therefore, by Pythagoras's theorem, DG = √(DF² - GF²) = √(28² - 11²) = √663 ≈ 25.75

You know that the number of pepperoni pizzas is 4 less than twice the number of cheese pizzzas. You also know that the number of combo pizzas is 8 less than the number of cheese pizzas. Finally, you know that the total number of pizzas ordered is 110.
Answers
Answer: See explanation
Step-by-step explanation:
Let the cheese pizzas be denoted by x.
Since pepperoni pizzas is 4 less than twice the number of cheese pizzzas. This will be:
= (2 × x) - 4.
= 2x - 4
Since combo pizzas is 8 less than the number of cheese pizzas. This will be:
= x - 8
Then we add all the pizzas and equate to 110. This will be:
x + (x - 8) + (2x - 4) = 110
x + x - 8 + 2x - 4 = 110
4x - 12 = 110
4x = 110 + 12
4x = 122
x = 122/4
x = 30.5
Therefore, cheese pizza = 30.5
Combo pizza = x - 8 = 30.5 - 8 = 22.5
Pepperoni pizza = 2x - 4 = 2(30.5) - 4 = 57

A business made $1.5 million in sales this year, and estimates a 7% increase in sales for the coming year.
If the company allocates 10% of expected sales for promotional activities, how much would be allocated (set aside) for next year's promotion (advertising)?
Answers
Answer:
$160,500
Step-by-step explanation:
First, find the coming years sales
7% of 1,500,000 is 105000
105,000+1,500,00=1,605,000
1,605,000 is the next year's sales and we do that *0.1 to find the advertising.
1,605,000*0.1=160,500
So 160,500 will be set aside for advertising

work out the size of angle A
Answers
Answer:
The measure of A is 93
Step-by-step explanation:
Here, we want to get the measure of angle A
we can start by getting the measure of angle C
Mathematically, we can use sine rule
It states that the ratio of the length of a side of a triangle and the sine of the angle it faces is constant
So to get C, we have the following;
9/sin 38 = 11/sin C
sin C = 11sin 38/9
sin C = 0.7525
C = sin^-1(0.7525)
C = 48.80
This is approximately 49
To get A,
we know that if we added the measure of interior angles of a triangle, the addition is 180 degrees
Thus, we have it that:
38 + 49 + A = 180
A = 180-38-49
A = 93
What is the 2nd term of the linear sequence

Answers
Answer:
5
Step-by-step explanation
Answer: 5
Step-by-step explanation:
aₙ = a + (n - 1) d
n = the term of the sequence that you're looking for (2)
a = 1st term of sequence (2)
d = common difference (3)
a₂ = 2 + (2 - 1) 3
a₂ = 2 + (1 × 3)
a₂ = 2 + 3
a₂ = 5
It's also given btw but in case you wanted to find other terms of the sequence.

==========================================================
Work Shown:
s = square side length
A = area of square = 9x^2+12x+4
A = s^2
A = (ax+b)^2
A = a^2*x^2 + 2abx + b^2 .... apply the FOIL rule
A = 9x^2 + 12x + 4
Equating corresponding terms, we see that,
a^2*x^2 = 9x^2 which shows that a^2 = 9 and that solves to a = 3, assuming 'a' is positive.2abx = 12x leads to 2ab = 12 or ab = 6. Using a = 3 we can find that b = 2.b^2 = 4 solves to b = 2 which matches with the previous value of b found.Using a = 3 and b = 2, the sum of the values is a+b = 3+2 = 5, so that's why the answer is choice C.
Side note: 9x^2 + 12x + 4 factors to (3x + 2)^2

Answer:
2
Step-by-step explanation:
to figure this out we need to convert the whole numbers into fractions with the same denominator as the fraction that is put with them
1 1/3 --> 3/3 + 1/3 = 4/3
1 1/2 --> 2/2 + 1/2 = 3/2
then we can take those values and multiply accordingly
4/3 * 3/2 = 2
(NOTE: if the problem allows it, you can convert the fractions into decimals by dividing the numerator by the denominator (3 / 2 = 1.50) but if it doesnt, then you can use this method in other problems)
hope this helps :)
