a: 7:3
b:by reading 10 hours
Answer:
a: 4 : 1
b: 12 (water) : 3 (sugar)
Step-by-step explanation:
ratio is similar to a fraction
water to sugar
the "to" is for what of every what it needs
to = can be used as ":"
For example:
For every 1 cup of sugar you need 4 cups of water to make the humming bird nectar. (it needs to be IN ORDER which is why for letter 'a' I did it water to sugar)

a=23 an= 5 n=10 find d
Answer:
d=-2
Step-by-step explanation:
a10=5, a10=a+(10-1)d
5=23+9d, d=-2
Answer:
d is -2
Step-by-step explanation:
From arithmetic progression:
[tex]{ \bf{a_{n} = a + (n - 1)d }}[/tex]
substitute:
[tex]{ \sf{5 = 23 + (10 - 1)d}} \\ { \sf{5 - 23 = 9d}} \\ { \sf{9d = - 18}} \\ { \sf{d = \frac{ - 18}{9} }} \\ \\ { \sf{d = - 2}}[/tex]

The average of five numbers is 34. Two of the numbers are the same, and the other three are 49, 25, and 42. Find the value of the two numbers missing numbers.
Answer:
Both numbers = 27
Step-by-step explanation:
( x + x + 49 + 25 + 42)/ 5 = 34 Multiply both sides by 5
(2x + 49 + 25 + 42) = 34*5 = 170 Combine the left
(2x + 116) = 170 Remove the brackets.
2x + 116 = 170 Subtract 116 from both sides
2x = 170 - 116
2x = 54 Divide by 2
x = 54/2
x = 27
Check
27 + 27 + 49 + 25 + 42
170 / 5 = 34
It does check out.
27 is right.

Simplify 4^2 ⋅ 4^8.
A)4^16
B)4^10
C)1^616
D)1^610
You will get 27pts if you answer this!!!
Answer:
4^2 * 4^8 = B)4^10
Step-by-step explanation:
When multiplying numbers with exponents, you will always add the exponents together. Therefore, 2+8=10 which is 4^10. You can also simplify the numbers and multiply them together. For example, 4^2=16 and 4^8=65,536 and when u multiply those numbers you get 1,048,576. The one that matches is 4^10=1,048,576.

Find the equation of the line passing through the point (-4, 4) and is perpendicular to the line y = 2x - 5.
Answer: y = (-1/2)x + 2
Concept:
When two lines are perpendicular to each other, their slopes are negative reciprocals.
The reciprocal of a number is 1 divided by the number.
In other words, it is the image opposite of a term.
Solve:
Given information
Given line = y = 2x - 5
Point = (-4, 4)
Find the slope of the line
Given the line is perpendicular to the line y = 2x - 5, the slope of the line would be negative reciprocal of the line y = 2x - 5.
Slope of line [y = 2x - 5] = 2
Slope of new line = (-1/2)
Find the y-intercept by substituting the given point
Equation of the new line: y = (-1/2)x + b
b = y-intercepty = (-1/2)x + b
4 = (-1/2) (-4) + b
4 = 2 + b
4 - 2 = 2 + b - 2
b = 2
Finalize the equation of the line
Slope = -1/2
Y-intercept = 2
[tex]\boxed{y=-\frac{1}{2}x+2 }[/tex]
Hope this helps!! :)

4) 2x(x+y)-(4x+2y)(3x-y)
Answer:
-10x² + 4xy - 2y²
Step-by-step explanation:
2x(x + y) - (4x + 2y)(3x - y)
= 2x² + 2xy - 12x² - 4xy + 6xy - 2y²
= 2x² - 12x² + 2xy - 4xy + 6xy - 2y²
= -10x² + 4xy - 2y²

A recipe for lemonade calls for 14 lemons for every 2 cups of sugar. If you have 84 lemons to use for making lemonade, how many cups of sugar will you need?
Answer: about 15 because 14x7=78 and 2 cups for every 14 so 7x2 is 14 and there is 6 remaining so 15 is about right
thank biggie not me
12 cups of sugar needed.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
for 14 lemons= 2 cups of sugar need.
for 1 lemon= 2/14 cups of sugar need.
Now, for 84 lemons
=84*2/14
=6*2
=12 cups of sugar need.
Hence, 12 cups of sugar needed.

A bag has 3 red marbles, 2 blue, 4 greens and 1 yellow. What is the probability of pulling a blue, putting it back
in the jar and then pull a green?
Show Your Work
Answer: 2/25
Step-by-step explanation: Since we are replacing the marbles, these two events are independent which means that the outcome of the first does not affect the outcome of the second.
First find the probability of selecting a blue marble.
There are 2 favorable outcomes, the blue marbles,
and 10 possible outcomes, all the marbles in the bag.
So the probability of selecting a blue marble is 2/10 or 1/5.
Always reduce when finding probability
Now we find the probability of selecting a green marble.
There are 4 green marbles and 10 total so the probability of
selecting a green marble is 4/10 or 2/5.
Now we multiply the probabilities.
So we have 1/5 x 2/5 or 2/25.

Use algebraic notation to describe how to transform the blue function into the red function. F\left(x\right)-1f(x)−1 f\left(x-1\right)f(x−1) f\left(x+1\right)f(x+1) f\left(x\right)+1f(x)+1
In geometry, transformations are used to move a point or points from one position to another. The notation that describes how the blue function is transformed into the red function is -f(x)
I have attached the graph of both functions.
From the attached graph, we can see that the blue function is reflected over the x-axis to produce the red function.
Let:
[tex]f(x) \to[/tex] Blue
[tex]g(x) \to[/tex] Red
The transformation of reflection across the x-axis is:
[tex]g(x) = -f(x)[/tex]
Hence, the notation that describes how the blue function is transformed into the red function is -f(x)
