Answer:
A) 24 B) [tex]\frac{35b}{56}[/tex]
Step-by-step explanation:
I'm making assumptions as the formatting is incorrect.
A) Q: Evaulate x in 8:3 = 64:x
8/3 = 64/x
8x = 192
x = 24
B) Q: Derive an equation for x in x:b = 35:56 with respect to b
56x = 35b
x = [tex]\frac{35b}{56}[/tex]
Jake is doing an experiment with bacteria in a petri dish and
an antibiotic that may kill the bacteria. The rate at which Jake
expects the antibiotic to kill the bacteria can be modeled by
the equation f(x) = 5,000(6), where x represents hours and
Rx) represents the number of remaining bacteria. As the time
approaches 10 hours, what value is f(x) approaching? (A.9D, RC
5, RS)
F) 0
G) 1
H) 5000
j) 2/9
Answer:
H) 5000
Step-by-step explanation:
1. Plug in numbers
10 = 5000*10
f(x) = 5000

Santosh spent $200, before tax, on a DVD player and DVDs. The player cost $120, new DVDs cost $15 and used DVDs cost $5. Santosh purchased the same number of new and uses DVDs. Write and solve an equation to find the number of each type of DVD Santosh purchased.
Answer:
Santosh purchased 4 new and 4 used DVDs.
Step-by-step explanation:
From the information given, as you know that Santosh spent $200 and that the DVD player cost $120, you can say that the new and used DVDs cost $80, which can be expressed as:
15x+5y=80, where:
x refers to the number of new DVDs
y refers to the number of used DVDs
Now, as the statement indicates that Santosh purchased the same number of new and used DVDs, this means that x is equal to y and you can replace y with x and solve for x:
15x+5x=80
20x=80
x=80/20
x=4
According to this, the answer is that Santosh purchased 4 new and 4 used DVDs.

Two angles in a triangle measure 102° and 670. What is the measure of the third angle?
0 110
0789
1139
O 169°
Step-by-step explanation:
step 1. wow! 670° I think you mean 67°
step 2. the 3 internal angles of a triangle add up to 180°. let x be the third angle
step 3. x + 102 + 67 = 180
step 4. x + 169 = 180
step 5. x = 11°.

At a teddy bear workshop, customers can select from black, brown, gold, white, blue, or pink for their bear's colors. If a father randomly selects two bear colors, what is the probability that he will select a white bear for his son and a pink bear for his daughter? The father cannot pick the same color for both bears.
Answer:
[tex]P(White\ and\ Pink) = \frac{1}{30}[/tex]
Step-by-step explanation:
Given
Colors: Black, Brown, Gold, White, Blue, Pink
Required
P(White and Pink)
Since the father can not select the same color, then it is a selection without replacement.
So, we have:
[tex]P(White\ and\ Pink) = [P(White)\ and\ P(Pink)][/tex]
[tex]P(White\ and\ Pink) = [P(White)\ *\ P(Pink)][/tex]
This gives:
[tex]P(White\ and\ Pink) = [\frac{1}{6}\ *\frac{1}{6-1}][/tex]
[tex]P(White\ and\ Pink) = [\frac{1}{6}\ *\frac{1}{5}][/tex]
[tex]P(White\ and\ Pink) = [\frac{1}{30}][/tex]
[tex]P(White\ and\ Pink) = \frac{1}{30}[/tex]

Answer:
D
Step-by-step explanation:
That is a negative correlation. As x increases, y decreases. Notice that as you read from left to right, the points are going down which means negative.
Mrs. Tirado picked 5/6 pounds of lettuce from her garden. Mrs. Rampulla picked 2/3 less pounds than Mrs. Tirado. How much lettuce did they pick altogether?
Step-by-step explanation:
Total amount of lettuce = x pounds
Mrs. Tirado picked 5/6 pounds of lettuce from her garden.
5 / 6 * Total amount = 5/6 x
Mrs. Rampulla picked 2/3 less pounds than Mrs. Tirado.
Mrs. Rampulla = 2/3 (Mrs. Tirado) = 2/3 (5/6 x)
Mrs. Rampulla = 5/9 x
How much lettuce did they pick altogether?
Mrs. Rampulla + Mrs. Tirado
5/9 x + 5/6 x
(25/18) x pounds

Answer:
x=12 y=6 m(ABC)=102 m(BCD)=78 m(DAB)=78
Step-by-step explanation:
alright mate so lets start with the properties of parallelogram:
Opposite angles are equal Sum of any two adjacent angles is 180degree(there are more but we will use those here)
so lets start with 1st property for help:m(BCD) is opposite angle for m(DAB) so those equations should be equal each other and this will give us a hint
[tex]6x+y=4x+5y\\2x=4y\\x=2y[/tex] i just changed the places of x to be in one place and s same for y then divided both sides by 2
Now lets use the 2nd property (sum of two adjacent angles is 180)m(ABC) is adjacent to m(BCD) so
[tex](7x+3y)+(4x+5y)=180[/tex] add x to x and y to y it will be
[tex]11x+8y=180\\[/tex]
Now we going to use the first one x=2y in this equation so we can deal with one variablereplace x with 2y so 11x will be 22y
[tex]22y+8y=180\\30y=180\\y=6[/tex] added the y to y and then divided both sides by 30
[tex]x=2y \\x=2*6=12[/tex]
now we got x and y
then lets start to substitute every x and y in the equations
[tex]7x+3y\\7*12+3*6=102\\[/tex] [tex]4x+5y\\4*12+5*6=78[/tex]3.[tex]6x+y\\6*12+6=78[/tex]
now we got everthing hope i helped you sorry also for being late it toook alot to type it so you can understand
