Peter is renting two kinds of rafts for a vacation company. One type seats 3
people and the other seats 5 people. If 53 people are using the vacation
company and he rents 13 rafts, how many of each type of raft does he rent?
Answer:
Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
Step-by-step explanation:
Let [tex]x[/tex] denote the number of rafts seating 3 people and [tex]y[/tex] the number of rafts seating 5 people. The total number of rafts is 13, so [tex]x+y=13[/tex]. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so [tex]3x+5y=53[/tex].
It's always a good idea to put these equations under each other:
[tex]\left \{ {{x+y = 13} \atop {3x+5y=53}} \right.[/tex]
We can subtract the first equation three times from the second one to obtain [tex](3x+5y)-3(x+y) = 53 - 3(13)\\3x-3x + 5y - 3y = 53 - 39\\2y = 14\\y=\frac{14}{2} = 7[/tex]
Now, substitute this found value for [tex]y[/tex] into [tex]x+y = 13[/tex] and we see that [tex]x=6[/tex]. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

Use quadrilateral ABCD. What value for m DAB would show ABCD is a parallelogram?
Answer:
m∠DAB = 101°
x = 7
y = 12
Step-by-step explanation:
Properties of a parallelogram,
1). Opposite sides of a parallelogram are equal and parallel.
2). Opposite interior angles are equal in measure.
3). Consecutive interior angles are supplementary.
By the first property,
BC ≅ AD
2x + 4 = 3x - 3
3x - 2x = 4 + 3
x = 7
AB ≅ CD
2y + 10 = 3y - 2
3y - 2y = 10 + 2
y = 12
By second property,
m∠ABC = m∠ADC
2z + 15 = 3z - 17
3z - 2z = 15 + 17
z = 32
Therefore, m∠ADC = (3z - 17)°
= 3(32) - 17
= 96 - 17
= 79°
By third property,
m∠ADC + m∠DAB = 180°
79° + m∠DAB = 180°
m∠DAB = 180° - 79°
m∠DAB = 101°

Fiber one bran cereal boasts that it contains 57% of the Daily Value of fiber you need. If 1 serving contains 15 gram of fiber, how much fiber do you need in one day
Answer:
26.3 grams
Step-by-step explanation:
57% of fiber is 15 grams. To find 1% you would divide 15 by 57 which is 0.2631578947. Now multiply 1% by 100 to get 100% fiber. The amount of fiber needed per day is 26.31578947 (the rounded answer is 26.3)

Step-by-step explanation:
Answer:
A) -13, -7, -3, 0, 3 B) -100, -99, -8, -25/3, -2
Step-by-step explanation:
3)Ordered from least to greatest is: -13, -7, -3, 0, 3
(The higher the negative the "smaller" it is)
4) -100, -99, -8, -25/3, -2
These numbers are listed in order from least to greatest with the error being -25/3. This equals -8.333 and should be in front of the -8 because it is a lesser value. The correct order would be: -100, -99, -25/3, -8, -2 but your answer asks for one error so use the numbers above.

marbles to the blue marbles?
A) 3/5
B) 3/8
C) 5/3
D) 5/8
Answer:

This gets you 5/3
So, the correct answer is C) 5/3
Answer:
5/3
Step-by-step explanation:
This is because there are 5 red marbles and there are 3 blue marbles. If you put them side by side, the ratio is 5:3 or 5/3.

Alex bought a total of 65 more raffle tickets than Juan. Together they bought 343
raffle tickets. How many raffle tickets did each download?
Answer:
Juan bought 139 tickets and Alex bought 204.
Step-by-step explanation:
Suppose Juan bought a total of [tex]x[/tex] tickets. Then Alex bought 65 more, which is [tex]x+65[/tex]. The sum of both totals is [tex](x)+(x+65) = 2x + 65[/tex], but we are also given that this is equal to 343. So [tex]2x+65 = 343[/tex], and as such [tex]2x = 343-65=278[/tex], so [tex]x = \frac{278}{2} = 139[/tex]. Therefore, Juan bought 139 tickets and Alex bought 65 more, which is 204.

Answer:
x³ - 2x² + 9x - 18x³ - 5x² + 3x + 9Step-by-step explanation:
1.
Zero's
x = -3i, x = 2 and the third zero is x = 3iPolynomial is:
(x + 3i)(x - 3i)(x - 2) =(x² - 9i²)(x - 2) =(x² + 9)(x - 2) =x³ - 2x² + 9x - 182.
Zeros:
x = 3, x = 3, x = -1Polynomial is:
(x - 3)(x - 3)(x + 1) = (x² - 6x + 9)(x + 1) =x³ + x² - 6x² - 6x + 9x + 9 =x³ - 5x² + 3x + 9What is the value of the expression r + 1,988 if r = 2,976?

.Abby, Neil and Dylan share a sum of money in the ratio 2:4:5 Neil receives £60 Work out how much money Dylan receives.
Answer:
Dylan should receive £75
Step-by-step explanation:
We know that
Abby, Neil, and Dylan share money in the ratios 2:4:5
This means that for every £2 that Abby has, Neil has £4, and Dylan has £5.
From this, we also know that for every £4 that Neil has, Dylan has £5.
Now we know that Neil receives £60
For each group of £4, Dylan will have £5.
Then we need to count how many times £4 is on £60, this is equal to:
£60/£4 = 15
And for each one of these, Dylan should receive £5, this is:
15*£5 = £75

The expressions which is equal to 10⁵ are 10³. 10² and 10 . 10 . 10 . 10 . 10.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
The given expression is 10⁵.
(10⁴)¹ = 10⁴
We have a rule of exponents,
xᵃ . xᵇ = xᵃ⁺ᵇ
10³. 10² = 10³ ⁺ ² = 10⁵
1 / 10⁵ = 10⁻⁵
(10³)² = 10^(3 × 2) = 10⁶
10 . 10 . 10 . 10 . 10 = 10⁵
Hence the equivalent expressions are 10³. 10² and 10 . 10 . 10 . 10 . 10.
