Answer:
x = 23
Step-by-step explanation:
If the sum of angles is equal to 180 then we can write and equation to find the value of x
5x + 10 + 55 = 180 add like terms
5x + 65 = 180 subtract 65 from both sides
5x = 115 divide both sides by 5
x = 23
If 10 apples cost $8.95, how much will 4 apples cost?
Step-by-step explanation:
here's your solution
=> cost of 10 apple = $ 8.95
=> cost of 1 apple = $8.95/10 = $ 0.895
=> cost of 4 apple = $ 0.895*4
=> cost = $3.580

CAN SOMEONE HELP ME PLEASE IM SO FRUSTRATED BECAUSE NO ONE IS HELPING ME PLS JUST BE NICE AND HELP ME PLS :’) NO LINKS NO BOTS OR JUST ANSWERS TO GET POINTS I WILL REPORT !!!Which of the following equations describes the line shown below? Check all
that apply.
(12,6) (4,4)
Answer:
I'm sorry that no one is helping you, the correct answers are A and F.
Step-by-step explanation:
The line's equation is [tex]y=\frac{1}{4} +3[/tex]. You know this because the slope of the line is found by subtracting the y-value of the two points and dividing it by the difference of the x-values, which would be [tex]\frac{6-4}{12-4} = \frac{2}{8} = \frac{1}{4}[/tex]. Using the slope, you can calculate the y-intercept of the equation, which you just multiply the slope by the distance to the y-axis and subtract that from the y-value of (4, 4), which you will get [tex]4 + (-4*\frac{1}{4}) = 4+(-1) = 3[/tex]. So the equation of the line is [tex]y=\frac{1}{4} +3[/tex]. When you simplify all the choices below, you'll get that only A and F are equivalent to the equation, so those are the correct choices.

4. What is the half-life of the radioactive isotope with amount A, whose rate of decay in t hours is shown in the graph below?
(0,40)
(20,15)
Answer:
15, 25
Step-by-step explanation:
Answer:The half life is the time taken for the amount of a substance to become half of its original value. If we take the initial value to be 30 on the y-axis, the half of 30 is 15. We check the time at which the substance has reduced to 15 atoms and this is about 40 seconds. The answer is C.

What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
A support wire is attached to the top of an antenna. The support wire connects to the ground 15 feet from the bottom of the antenna.
Let x be the height of the antenna.
We can find the length of the antenna using the trigonometric ratios:
As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
Applying tan ratio in the right angle triangle:
tan70 = x/15
x =15tan70
x = 41.212 feet ≈ 41.23 feet
Thus, the height of the antenna is 41.23 feet if the support wire is attached to the top of the antenna.

How many quart are 8/1/4 gallons
Given:
Consider the given gallons are [tex]8\dfrac{1}{4}[/tex] gallons.
To find:
The number of quarts in [tex]8\dfrac{1}{4}[/tex] gallons.
Solution:
We know that,
1 gallons = 4 quarts
Using this conversion, we get
[tex]8\dfrac{1}{4}\text{ gallons}=4\times 8\dfrac{1}{4}\text{ quarts}[/tex]
[tex]8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{32+1}{4}\text{ quarts}[/tex]
[tex]8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{33}{4}\text{ quarts}[/tex]
[tex]8\dfrac{1}{4}\text{ gallons}=33\text{ quarts}[/tex]
Therefore, there are 33 quarts in [tex]8\dfrac{1}{4}[/tex] gallons.

Q1 : Gina writes the letters of the word PROBABILITY on separate cards. She picks one card at random. What is the probability that the card Gina selects is:
a) The letter B
b) A vowel
c) A letter before M in the alphabet?
Answer:
2/11
4/11
6/11
Step-by-step explanation:
probability the letter B = number of times b appears in the word / total number of alphabets
total number of alphabets = 11
number of times b appears in the word = 2
2/11
a vowel = total number of vowels in the word / total number of alphabets
vowels include = a,e,i,o,u
vowels in the word = a, o, i
total number of vowels in the word = 4
4/11
A letter before M in the alphabet = total number of alphabets before m in the word / total number of alphabets
letters before m = A, B, C, D, E, F, G, H, I, J, K, L
letters before m in the word = b,a, i , l
number of words before m = 6/11
You 5-year loan of $14,000 is at 4.3% compounded annually. How much will you have paid in total for your loan?
Answer:
$17,276
Step-by-step explanation:
Given data
Time= 5 years
Principal= $14,000
Rate= 4.3%
We want to find the final amount
A=P(1+r)^t
Substitute
A= 14000(1+0.043)^5
A= 14000(1.043)^5
A= 14000*1.234
A=$17276
Hence the total amount is $17,276

PLEASE HELP THIS HAS A TIMER The following two-way table shows the distribution of daily traffic and weather issues in a certain large city.
A 4-column table with 3 rows. Column 1 has entries bad weather, good weather, total. Column 2 is labeled heavy traffic with entries 25, 55, 80. Column 3 is labeled Light traffic with entries 5, 15, 20. Column 4 is labeled Total with entries 30, 75, 100. The columns are titled daily traffic and the rows are titled weather conditions.
Suppose a day from this city is selected at random. Let event A = heavy traffic and event B = bad weather. Are events A and B independent?
No, P(A) = P(B|A).
No, P(A) ≠ P(A|B).
Yes, P(A) = P(A|B).
Yes, P(A) ≠ P(B|A).
Answer:
I believe the answer is (B).
Both are not independent, and the probability of A is 30/100.
While the probability for A|B is like 30/100(80/100) which does not equal 30/100.
I've been trying to figure out how to do it and stuff, and this seems the most reasonable answer. I'm taking it now. Goodluck

The two events are not independent as the traffic is affected by the weather conditions.
What is independent probability?Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B).
Let event A = heavy traffic and event B = bad weather.
P(A)= 25/30 and P(B)=25/30
Two events are said to be independent only when the change in one event affect the other event.
Here the two given events are not independent.
Band weathers such as heavy rainfall, snowfall etc. leads to failure of traffic management system and thereby causes heavy traffic. This is easily seen in all major urban cities.
Hence, the two events are not independent as the traffic is affected by the weather conditions.

Rachel ran 3 miles when she was training for a race. How many feet did she run?
Answer:
15,840 i did this in test and got 100%
Step-by-step explanation:
The total feet ran by Rachel is given by the equation A = 15,840 feet
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the total miles ran by Rachel be A = 3 miles
Now , the value of 1 mile = 5,280 feet
Substituting the values in the equation , we get
The distance of 3 miles in feet = 3 x value of 1 mile
On simplifying the equation , we get
The distance of 3 miles in feet = 3 x 5,280
The distance of 3 miles in feet = 15,840 feet
Therefore , the distance ran by Rachel A = 15,840 feet
Hence , the equation is A = 15,840 feet
