help me i dont really understand
Answer:
73
Step-by-step explanation:
12(6) + 1/4 • 2^2
Square the 2 first.
12(6) + 1/4 • 4
Then multiply from left to right.
72 + 1
Lastly, add.

The parenthesis around the 6 mean multiplication, not the Parenthesis that are grouping symbols if you are learning PEMDAS. So your question has no grouping symbol parenthesis. Next comes Exponents, that's why we squared the 2. Multiply and Divide come next IN THE ORDER THAT THEY APPEAR FROM LEFT TO RIGHT. Then the same method with adding and subtracting. That's called the order of operations.

A = the outcome is less than 6, B = the outcome is more than 1
You start driving west for 3 miles, turn right, and drive north for another 13 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.
Answer:
13.3 miles to nearest 1/10.
Step-by-step explanation:
The journey forms a right triangle so by Pythagoras:
d^2 = 3^2 + 13^2
d^2 = 9 + 169
d^2 = 178
d = 13.34 miles.
You have 976 grams of a radioactive kind of rhodium. How much will be left after 120 seconds if its half-life is 30 seconds?
grams
there will be approximately 61 grams of the radioactive rhodium remaining after 120 seconds.
What are exponential growth and decay?A rise in the resultant quantity for a given quantity is referred to as exponential growth, and a decrease in the resultant quantity for a given quantity is referred to as exponential decay. Over time, exponential functions monitor constant growth. Examples from the actual world include radioactive decay, compound interest, and bacterial proliferation.
Given, You have 976 grams of a radioactive kind of rhodium.
The formula for the amount of a substance remaining after a certain amount of time given its half-life is:
N = N₀ *[tex](1/2)^{t / t_{1/2} }[/tex]
where:
N₀ is the initial amount of the substance
N is the amount of the substance remaining after time t
t₁/₂ is the half-life of the substance
In this problem, N₀ = 976 grams, t = 120 seconds, and t₁/₂ = 30 seconds. We can plug these values into the formula and solve for N:
N = 976 * (1/2)⁽¹²⁰/³⁰⁾
N = 976 * (1/2)⁴
N = 976 * 0.0625
N ≈ 61
Therefore, after 120 seconds, there will be approximately 61 grams of the radioactive rhodium remaining.

Answer:
A
Step-by-step explanation:
Vertical line test. Draw vertical lines (you don't have to actually draw them, imagine them) across the relation. If any line intersects two portions of the relation, it is not a function.
What is true when a system of equations has no solution?
The lines intersect in one place.
The lines are parallel and do not intersect.
The lines coincide (are the same line).
This is impossible
Answer:
D. This is impossible
Step-by-step explanation:
In math, when you solve an answer and you’re given no solution, it means that whatever equation you just did cannot be solved, and is therefore, impossible; there is no answer.
Side note: If you have any further questions feel free to let me know.

Step-by-step explanation:4 pounds equal to 1 dollar so that means that each pound equals to 0.25 cents. SO, now you multiply 0.25 x 5= 1.25
what type of bias can occur
survey question “how many words per minute can you read?”
People may have a bias towards whether they read fast or slower on purpose because they believe they will retain more information that way (each person is different). If your taking a wpm test, for example, you won't pay attention to comprehension, only speed. Another bias is the type of book your reading and whether you enjoy it. Studies prove that you tend to soak in more information and read faster when you are enjoying the book.

Discussion and Correction
The algrebra itself is fine. The exclusions are not so good. The difficulty comes in the denominator. It factors into (2x)(x - 3). x cannot take on a value of 0 (that was pointed out and that is correct). The problem comes in the plus/minus 3. Plus 3 is correct. x - 3 will come 0 if x = 3. Nothing bad will happen if x = - 3
Answer: So the exclusions in the denominator should be modified to x = 3.
Answer:
The excluded values are x-values that make the denominator of the original expression zero, since [tex]\dfrac{a}{0}[/tex] is undefined.
[tex]x = -3[/tex] is not an excluded value since this x-value does not make the denominator zero.
[tex]x = -3[/tex] makes the numerator zero, but as [tex]\dfrac{0}{a}=0[/tex] it is not an excluded value.
Therefore, step 3 of her work should read:
[tex]\textsf{Finding excluded values}:x\neq 0\:\textsf{and}\:x\neq 3[/tex]

What number, when divided by 6, is equivalent to 15?
n=90
n=5/2
n=4
n=15
Answer:
90
Step-by-step explanation:
15+15=30
3x30=90
Therefore, the answer to what divided by 6 equals 15 is 90. You can prove this by taking 90 and dividing it by 6, and you will see that the answer is 15. Tip: For future reference, when you are presented with a problem like "What divided by 6 equals 15?", all you have to do is multiply the two known numbers together.
Therefore, n=90 is your correct answer
A 9-pound bag of sugar is being spilt into containers that hold 2/3 of a pound. How many containers of sugar will the 9-pound bag fill?

An item is regularly priced at $76. It is now priced at a discount of 80% off the regular price.
Answer:
Sale price:
The price after the original price has been discounted.Our goal is to find the sale price.
We could use either of the two methods shown below:
Find what the discount price is, and reduce that off the original price.
Or
Simply find the sale price by finding the leftover percentage of the discount and multiplying it by the original price.
Let's use the second technique.
The leftover percentage of 80% is 20%, because;
100 - 80 = 20%.
Now multiply this percentage with the original price:
20%(can be considered 20/100), so
20/100 × $76
= 15.2, the sale price of this item is $15.20!

Answer: 6.3
Step-by-step explanation:
Which expression is equal to:
4b + 4c / z
a. 4(b + c) / z
b. 4b(4c / z)
c. 8bc / z
d. (b + c) ● (4+z)
(marking brainliest)
4(b + c) / z
Reason:
We factor 4 from 4b+4c to get 4(b+c). The z in the denominator stays where it is. This factoring is possible because of the distributive property.
This is why [tex]\frac{4b+4c}{z}[/tex] is the same as [tex]\frac{4(b+c)}{z}[/tex]
Side note: you should use parenthesis to write (4b+4c)/z, which indicates all of 4b+4c is over top the z. This is because 4b+4c/z might get mistaken for [tex]4b+\frac{4c}{z}[/tex]

What is the measure of the missing angle?
Answer:
The missing angle = 113°
Step-by-step explanation:
Let the missing angle be x
Sum all angles in a triangle = 108°
34° + 33° + x° = 108°
x° = 108° - 34° - 33°
x° = 113°
!!PLEASE PLEASE PLEASE PLEASE PLEASE MARK ME THE BRAINLIEST!!
Answer:
[tex]\tt x=113^o[/tex]
Step-by-step explanation:
We know that the sum of angles in a triangle is always 180°.
So the sum of the three angles must be 180°.The two angles you know measure 34° and 33°.
Now, let's write an equation and find the measure of the unknown angle:-
[tex]\tt 34^o+33^o+ x=180^o[/tex]
[tex]\tt 67^o+x=180^o[/tex]
[tex]\tt x=180^o-67^o[/tex]
[tex]\tt x=113^o[/tex]
Therefore, the measure of the missing angle is 113°.
lara makes salad dressing by mixing 8
spoonfuls of oil and some vinegar. The tape
diagram shows the ratio of oil to vinegar.
Answer:
3:6
Step-by-step explanation:
8 ÷ 4 = 2
2 ÷ 1 = 2
6 ÷ 3 = 2
Answer:
1. 2:8
2. 1:4
3. 3:12
Step-by-step explanation:
There are 2 parts of oil for every one part of vinegar.
2+1=3
The ratio is made up of 3 total parts.
The part to whole ratio of oil to total is 2:1.
We are looking for an equivalent ratio that has 8 spoonfuls of oil.
If we have 4 times as much oil, we also need 4 times as much vinegar.
Also, we will have 4 times as much total dressing.
2x4=8
1x4=4
3x4=12
