Michael, Leo and JuWoong collect stamps. The ratio of the number of Michael's stamps to JuWoong's stamps is 2:7. The number of JuWoon's stamps is 3/4 of the number of Leo's stamps. If Leo has 396 more stamps than Michael, how many stamps do they have altogether?
Answers
Answer:
990
Step-by-step explanation:
M/J = 2/7
J = 3/4 L
L = M + 396
7M = 2J
J = 3.5M
3.5M = 3/4 L
L = 4/3(3.5M)
L = 14/3 M
14/3 M = M + 396
11/3 M = 396
M = 3/11 × 396
M = 108
L = M + 396
L = 108 + 396
L = 504
J = 3/4 L
J = 3/4 × 504
J = 378
M + L + J = 108 + 504 + 378 = 990

Find the values of x and y. Write your answers in simplest form.
Answers
Answer:
To find X you'll need this formula Tan 30, and this one to find y cos 30.
Step-by-step explanation:
tan 30 = 9 / x.
tan 30*x = 9
x = 9 / tan 30
x = 15.58
To find y, the value of X will be needed, which is 15.5 that we just found.
Cos= A/H
Cos 30 = 15.58/ y
Cos 30 * y = 15.58
y = 15.58/ cos 20
y = 17.99
F(x)= -3x2^-3x, f(-2)
Answers
Answer:
-6
Step-by-step explanation:
We know that the equation is f(x)=-3x^2-3x.
This means when we plug -2 in, the equation will be f(-2)=-3(-2)^2-3(-2). Simplify this to get -3(4)+6. Simplify this to get -12+6 which is equal to -6. Therefore, f(-2)=-6

p=(4,3) and q=(-2,7), find 4p -2q
Answers
Answer:
(20, -2)
Step-by-step explanation:
Given the coordinate vectors p=(4,3) and q=(-2,7),
4p - 2q = 4(4, 3)- 2(-2, 7)
4p - 2q = (16, 12) - (-4, 14)
4p - 2q = (16+4, 12-14)
4p - 2q =(20, -2)
hence the required vector is (20, -2)

A bag has 6 blue marbles, 4 red marbles, and 2 green marbles. Wo marbles are randomly chosen without replacement. What is the probablilty that both marbles piked are blue
Answers
Answer:
5/22
Step-by-step explanation:
A bag has 6 blue marbles, 4 red marbles, and 2 green marbles. Wo marbles are randomly chosen without replacement.
Total number of marbles =
6 blue marbles + 4 red marbles + 2 green marbles
= 12 marbles
The probability of picking a blue marble = P(B) = 6/12
Therefore, the probablilty that both marbles picked are blue without replacement is
= 6/12 × 5/11
= 30/132
= 5/22

3/10 is the Probability of not Drawing Blue Marbles
Step-by-step explanation:
Blue Marbles = 7
Green Marbles = 2
Red Marbles = 1
Total Marbles = 7 + 2 + 1 = 10
Probaility of Drawing Blue Marbles = 7 /10
Probability of not Drawing Blue Marbles = 1 - Probaility of Drawing Blue Marbles
= 1 - 7/10
= 3/10
or
Probability of not Drawing Blue Marbles = Probability of drawing Green or Red Marbles
= 2/10 + 1/10
= 3/10
3/10 is the Probability of not Drawing Blue Marbles

Some steps to rewrite the expression x3 − 16x + x2 − 16 as a product of three factors are shown below:
Step 1: x3 − 16x + x2 − 16
Step 2: x3 + x2 − 16x − 16
Step 3: x2(x + 1) − 16(x + 1)
Which of the following best shows the next two steps to rewrite the expression?
Step 4: (x2 + 16)(x + 1); Step 5: (x + 4)(x + 4)(x + 1)
Step 4: (x2 − 16)(x + 1); Step 5: (x + 4)(x + 4)(x + 1)
Step 4: (x2 − 16)(x + 1); Step 5: (x − 4)(x + 4)(x + 1)

rectangle with a length of 360 miles and a width of
280 miles. If the population of Wyoming in 2010
was 490,408; what was the population density?
Round your answer to the nearest hundredth.
Answers
Answer:
4.86 people/sq.miles
Step-by-step explanation:
the area of the state of Wyoming =
360 × 280 = 100,800 sq. miles

490,408 ÷ 100,800
= 4.86 people/sq.miles

Answer:45.5
Step-by-step explanation:
Answer:
y = 45.5
Step-by-step explanation:
[tex]\frac{3.25}{y}: \frac{2.5}{35}[/tex]
y · 2.5 = 3.25 · 35

slove the equestion. m^2+3m+2=0
Answers
Answer:
-2, -1
Step-by-step explanation:
m^2 + 3m +2 = (m+1)(m+2)
(m+1) = 0, m = -1
(m+2) = 0 , m= -2
so m is -1 or -2
Answer:
The solution set is {-2, -1}.
Step-by-step explanation:
m^2 + 3m + 2 = 0
(m + 1)(m + 2) = 0
m + 1 = 0 gives m = -1,
m+2 = 0 gives m = -2.
