Answer:
1). x = 40
2). y = 20
Step-by-step explanation:
1). "4x" y "160" son ángulos de vértice, por lo que son congruentes entre sí. Entonces, "4x = 160" y luego usa álgebra para resolver "x" y "x = 40".
2). "Y" y "4x" son ángulos suplementarios, por lo que si ambos se suman, forman un ángulo de 180. Entonces, "Y + 4 (40) = 180", usando álgebra daría la respuesta "Y = 20".
¡Espero que esto ayude!
plz help! : Two math classes took the same quiz. The scores of 10 randomly selected students from each class are shown below.

solve for y: 36=byx
Answer:
y= 36/bx
Step-by-step explanation:
you have to isolate y so you do the inverse operation of b and x to move it to the other side. since it is currently multiplying by Y you divide it on both sides to move it leaving you with 36 being divided by BX .
I'm confused I put 13-x and it said incorrect?? HELP!
Answer:
Maybe -12?
Step-by-step explanation:
Because sometimes variables on their own symbolize 1, so we can subtract 13 from 1 to get -12.

Answer:
So the scaling means that per every foot in real life, you have 2.4 centimeters, which means that the scale model would be 48 cm tall.
A. To find your answer, you would divide 48 by 1.2, which is 40. So your model would be 40 bottle caps tall
B. Same as A, all you have to do is divide 48 by 15.2, which would be about 3 popsicle sticks tall (rounded)

(1-1) (1-2) (1-3) (2-1) (2-2) (3-1)
Answer:
its the 3rd answer in the row :)
Step-by-step explanation:
Step-by-step explanation:
First, you need to know some terms related to probability. When working with probability, a random action or series of actions is called a trial. An outcome is the result of a trial, and an event is a particular collection of outcomes. Events are usually described using a common characteristic of the outcomes.
Let's apply this language to see how the terms work in practice. Some games require rolling a die with six sides, numbered from 1 to 6. (Dice is the plural of the die.) The chart below illustrates the use of trial, outcome, and event for such a game:
Trial
Outcomes
Examples of Events
Rolling a die
There are 6 possible outcomes:
{1, 2, 3, 4, 5, 6}
Rolling an even number: {2, 4, 6}
Rolling a 3: {3}
Rolling a 1 or a 3: {1, 3}
Rolling a 1 and a 3: { } (Only one number can be rolled, so this outcome is impossible. The event has no outcomes in it.)
Notice that a collection of outcomes is put in braces and separated by commas.
A simple event is an event with only one outcome. Rolling a 1 would be a simple event because there is only one outcome that works—1! Rolling more than a 5 would also be a simple event because the event includes only 6 as a valid outcome. A compound event is an event with more than one outcome. For example, in rolling one six-sided die, rolling an even number could occur with one of three outcomes: 2, 4, and 6.
When you roll a six-sided die many times, you should not expect any outcome to happen more often than another (assuming that it is a fair die). The outcomes in a situation like this are said to be equally likely. It’s very important to recognize when outcomes are equally likely when calculating probability. Since each outcome in the die-rolling trial is equally likely, you would expect to get each outcome of the rolls. That is, you'd expect the rolls to be 1, of the rolls to be 2, of the rolls to be 3, and so on.
A spinner is divided into four equal parts, each colored with a different color as shown below. When this spinner is spun, the arrow points to one of the colors. Are the outcomes equally likely?
A) Yes, they are equally likely.
B) No, they are not equally likely.
Answer:
All the outcomes are equally likely. Each color provides a different outcome, and each color takes up the circle. You would expect the arrow to point to each color of the time.
Here is to my last q
Answer: D (Mean is 85)
Explanation:
"The list below shows the quiz scores for a group of students.
95, 80, 80, 85, 80, 85, 90"
The choices talk about median and mode so we find those first:
Median: find by taking which is the middle number when the data is from low to highest
1) rearrange them from low to high
80, 80, 80, 85, 85, 90, 95
2) find middle number
80, 80, 80, 85, 85, 90, 95
The median is 85
Mean: mean is the average of all numbers. Find by adding numbers and dividing by amount of numbers
1) add 80, 80, 80, 85, 85, 90, 95 and get 595
2) There are 7 total numbers so do 595/7 = 85
The mean is 85
D is the correct answer
why?
A is wrong because they are 85 not 80
B is wrong because it is 85 not 80
C is wrong because it is 85 not 80
D is right because it is 85!

Answer:
2x^3−7x^2+16x−15
Step-by-step explanation:
(2x−3)(x^2−2x+5)
=(2x+−3)(x^2+−2x+5)
=(2x)(x^2)+(2x)(−2x)+(2x)(5)+(−3)(x^2)+(−3)(−2x)+(−3)(5)
=2x^3−4x^2+10x−3x^2+6x−15
=2x3−7x2+16x−15
Answer:
2x³ -7x² +16x -15
Step-by-step explanation:
You distribute the (2x-3) onto the other trinomial and then combine the like-terms.
(2x-3)(x²-2x+5)
2x³ -4x² + 10x -3x² +6x -15
2x³ -7x² +16x -15

Walden gives the pizza delivery person an $8.00 tip, which was 12% of the cost of his pizzas. How much was the total amount that Walden spent? Round your answer to the nearest cent.
ANSWERS WITH WEIRD FILE THINGYS WILL BE REPORTED IMMEDIATLY
Answer:
$17
Step-by-step explanation:
Tip = $8.00
Pizzas cost:
First you have to do 12% of $8.00 which = $0.96
Then you have to add the $0.96 to the $8.00 which = $8.96
Total = $8.00 + $8.96
= $16.96
then round it to nearest cent which is $17
Answer:
$74.67
Step-by-step explanation:
$8 was 12% of the cost of the pizzas, so we have to add that to the initial cost. The initial cost can be found by (8*100)/12, which would be $66.67. Since we need to find the total amount of money spent, we have to add the initial cost of pizzas and the $8 tip, which is 12% of that. Final answer is $74.67
