42 x 8= 336
68 x 14= 952
And it dosen't matter if you have a multi- numberd equation, because either way you can use a calculator to do the math. and a trick for multiplying by 10 or 100 or 1000: is lets say you have 5 x 1000, instead of doing any math just multiply 1 x 5= 5 then add 3 zero's because 1000 has 3 zeros. You can do this with any number like 10,100,1000,10000 ; you could go on forever.
A vase has 4 yellow flowers, 4 red flowers, and 8 blue flowers. Donna took a flower smelled it and put it back ,then took another flower and smelled it. What is the probability that the first flower was red and the second flower was blue?
Answer:
1/8
Step-by-step explanation:
Since the flower was replaced, these two drawings are independent events and the final probability is the product of the two individual probabilities.
total number of flowers: 16
yellow: 4
red: 4
blue: 8
p(red) = 4/16 = 1/4
p(blue) = 8/16 = 1/2
p(red then blue) = 1/4 × 1/2 = 1/8
Answer: 1/8
given that ax60=b work out the value of 4b/a
Answer:
Given,
a x 60 = b
or
b = a x 60
Similarly, the value of a would be:
We need to find
Therefore, we have to put the either values of a and b in the specified equation:
Hence,
We have only put the value of one variable to evaluate or to make it variable free
or
Therefore, the value of 4b/a is 240.

Answer:

Step-by-step explanation:
Evaluate (2 minus 5 i) (p + q) (i) when p = 2 and q = 5 i.
29 i
29 i - 20
- 21 i
29
Answer:
29 i
Step-by-step explanation:
As the expression given in the question.
= (2 - 5i) (p + q)i
Simplify the above
= (2 - 5i) (pi + qi)
= 2pi + 2qi - 5pi²- 5qi²
As i² = -1
Put in the above
= 2pi + 2qi + 5p +5q
= 2i × 2 + 2i × 5i + 5 × 2 + 5 × 5i
= 4i + 10i² + 10 + 25i
As i² = -1
= 4i - 10 + 10 + 25i
= 29i
Thus the value of the (2 – 5i)(p + q)i is 29i .

Which is the largest ratio?
StartFraction 5 Over 36 EndFraction, 2:9, 3 to 18, 1:3
Answer:
Convert these ratios into fractions and then into their actual values.
(This is just one way of solving this, there are other plentiful ways you could use to solve this.)
2 : 9
Will become
2/9
Which will result in
0.222...
3 : 18
Will become
3/18
Which will result in
0.1666...
1 : 3
Will become
1/3
Which will result in
0.333...
Now, compare these numbers:-
0.222..., 0.1666..., and 0.333...
And out of these three numbers, 0.333... is by far the greatest number out of all of these ratios.
Therefore, the ratio 1:3 is the largest ratio.
What is the distance between points (8,3) and (53,31) on a coordinate plane?
Answer:
53 units
Step-by-step explanation:
Let [tex](x_1,y_1)\rightarrow(8,3)[/tex] and [tex](x_2,y_2)\rightarrow(53,31)[/tex] to use the distance formula:
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\\\d=\sqrt{(31-3)^2+(53-8)^2}\\\\d=\sqrt{(28)^2+(45)^2}\\\\d=\sqrt{784+2025}\\\\d=\sqrt{2809}\\\\d=53[/tex]
Thus, the distance between the two points is 53 units

A washer and dryer cost a total of $964 . The cost of the washer is three times the cost of the dryer. Find the cost of each item.
Answer:
A washer and dryer cost a total of $964 . The cost of the washer is three times the cost of the dryer. Find the cost of each item.
Answer: 96$
Answer:
The washer costs $723 and the dryer $241.
Step-by-step explanation:
Represent the cost of the washer by w and that of the dryer as d.
Then w = 3d.
Since w + d + $964, we get 3d + d = $964, or 4d = $964, or d = $241.
Three times that is $723.
The washer costs $723 and the dryer $241.

Step-by-step explanation:
1.) You need to know the exponential growth and decay formula.
The formula: y=ab^x
**For no.1**
Your initial amount is 300 which is the a
You need to do 100%+8% which is 108%

Compare learning about functions to learning a new language. How are they similar?
Answer:
Similarities
They both follow strict laws (typically stricter for math).
Practice makes perfect: both can be learned to points of practical perfection.
The brain must first attribute meaning or value to elements of either in order to build a learning pattern.
Differences:
Math is learned under assumptions of perfection (2 + 2 = 4 ALWAYS); whereas, language is learned under assumptions of reality (2 + 2 may be 5 for significantly larger values of 2). In other words, 2 average sized men plus 2 average sized Texans would more likely equal 5 or more average sized men.
Math is logical and language is largely artistic.
There is only one solution (or specific set of solutions) to every math problem. On the other hand, there are at least 100 different ways to express the same idea using language.
Step-by-step explanation:
Answer:
Language rules could be compared to syntax rules that govern the writing and scripting of a function. Language-based rules could be compared to syntax rules when writing functions, such that when the guiding syntax is correctly displayed, the function is clear and easy to read.

A rectangular field has a perimeter of 300m. What is the area of the field if the length of the field is twice the width of the field
Answer:
5000 square meters
Step-by-step explanation:
Create a rectangle and use any variable to lable it.
I used c and I know that the length is twice the width, so I added "c" for both widths and "2c" for both lengths.
Count the number of c's up and you will get 6.
Divide 300/6 to get the value for c.
You get 50 for c, so plug it in for the length 2(50) or 100, and plug it in for the width or 1(50).
Now that you have the length and width of the triangle, use length times width to find the area.
100x50=5000
The sum of two consecutive odd numbers is 28. Find their product
We will see that the first odd number is 13 and the second odd number is 15, the product is:
P = 13*15 = 195
How to find the two consecutive odd numbers?
Let's say that the first number is x, the next odd number will be x + 2.
The sum of these two odd numbers must be 2, then we need to solve the linear equation:
x + (x + 2) = 28
We can solve that for x:
2x + 2 = 28
2x = 28 - 2 = 26
x = 26/2 = 13
Then the first number is x = 13 and the second number is x + 2 = 13 + 2 = 15.
The product of these two numbers is:
13*15 = 195

3w(x + y) + 4z(x - y) correctly shows the first step when factoring 3wx + 3wy - 4zx - 4zy by grouping. Option B
How to solve thisTo factor by grouping, we first pair up the terms and then check if there is a common factor in each pair.
The given expression is 3wx + 3wy - 4zx - 4zy
First, put the terms into pairs.
The simplified version of the expression (3wx + 3wy) - (4zx + 4zy) is 3wx + 3wy - 4zx - 4zy.
Next, separate and remove the terms that are the same from each group.
The expression 3w(x + y) - 4z(x + y) can be simplified to (3w - 4z)(x + y).
This is a summary:
In option B, we have correctly put the terms together in pairs and found the common factors in each group. In the first group, we take out 3w from 3wx and 3wy, and in the second group, we take out 4z from 4zx and 4zy. This means that the expression is correct when it is written as factors.
