Work out the value of x.
Need answer soon :)
Answer:
x+20
Step-by-step explanation:
As we can see n the diagram, there are parallel traversals and one line, and the two angles given are same-side interior angles. We know that when there is parallel traversal, and we have same side interiors, the sum of the measure of the two angles are supplementary. Supplementary means 180 degrees, or a straight line.
So we plug everything in and we have 4x+5x=180 degrees
4x+5x=9x, so 9x=180
We divide by 9 on both sides to get the value of x, which is 20
Hope it helps!
Assume that y varies inversely with x. If y= 16 when x = 0.5, find y when x = 32.
y=[ ? ]
The constant of variation k for the inverse variation is found to be 8. When x = 32 is substituted into the formula y * x = k, we find that y = 0.25.
Explanation:In problems where y varies inversely with x, it means that their product is constant. This can be represented as y * x = k, where k is the constant of variation. Given that y = 16 when x = 0.5, we can find the constant by plugging these values into the formula. Hence, 16 * 0.5 = k, so k = 8.
Now to find y when x = 32, we substitute these values into the formula. We know that y * 32 = 8, so y = 8 / 32. This simplifies to y = 0.25.

can a triangle have to acute angles and one obtuse angle
Answer:
yes
Step-by-step explanation:
Any obtuse triangle will also have two acute angles.
__
The sum of angles in a triangle is 180°. If one of the angles is 90° or more (a right or obtuse angle), the other two (non-zero) angles must be less than 90°.
An obtuse triangle is one that has an obtuse angle, so both of the remaining angles must be less than 90°, that is, they must be acute angles.
Answer:
Yes
Step-by-step explanation:
Example:
A triangle with angles: 100°, 50°, 30°
Given ΔSTU and ΔDEF, what is m∠U ?
In this context:
[tex]\boxed{m\angle U=40^{\circ}}[/tex]
Explanation:Hello! Remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any diagram, so I'll assume ΔSTU and ΔDEF are similar. Two triangles are similar if and only if their corresponding angles are congruent and their corresponding sides are in proportion.
So:
[tex]\angle S=\angle D \ldots eq1 \\ \\ \angle T=\angle E \ldots eq2 \\ \\ \angle U=\angle F \ldots eq3[/tex]
We also know:
[tex]\angle S+\angle T+\angle U=180^{\circ} \ldots eq4 \\ \\ \angle D+\angle E+\angle F=180^{\circ} \ldots eq5[/tex]
Suppose we know:
[tex]\angle S=30^{\circ} \\ \\ \angle E=110^{\circ}[/tex]
Then, by eq2:
[tex]\angle T=\angle E =110^{\circ}[/tex]
By substituting ∠S and ∠T into eq4:
[tex]\angle S+\angle T+\angle U=180^{\circ} \\ \\ 30^{\circ}+110^{\circ}+\angle U=180^{\circ} \\ \\ \\ Isolating \ \angle U: \\ \\ \angle U=180^{\circ}-(30^{\circ}+110^{\circ}) \\ \\ \angle U=180^{\circ}-140^{\circ} \\ \\ \angle U=40^{\circ}[/tex]
Finally:
[tex]\boxed{m\angle U=40^{\circ}}[/tex]

There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting at least 1 red?
Answer:
1/7
Step-by-step explanation:
i learned this arealdy
The probability of drawing at least one red marble from a bag containing 3 blue and 5 red marbles in two draws without replacement is 19/28.
To find the probability of drawing at least one red marble from a bag with 3 blue and 5 red marbles, with one draw already taken, we calculate the probability of not drawing a red marble and subtract that from 1. Since there are more red than blue marbles, the probability of drawing a red one on the first draw is higher. However, the problem states that the marbles are not replaced after drawing, so the probabilities change with every draw.
There are two ways to not draw a red marble in two draws:
First draw: blue, Second draw: blue.
First draw: red, Second draw: blue.
Let's calculate these probabilities. For the first case, there's a 3/8 chance of drawing blue first, and then 2/7 chance of drawing blue again, since one blue marble has been removed, which equals to 3/8 * 2/7 = 6/56 or 3/28. For the second case, there is a 5/8 chance of drawing red first, and then a 3/7 chance of drawing blue, equalling 5/8 * 3/7 = 15/56. The sum of these probabilities is 3/28 + 15/56 = 9/28.
Therefore, to find the probability of at least one red, we subtract the summed probabilities from 1: 1 - 9/28 = 19/28.
Thus, the probability of drawing at least one red marble is 19/28.
A delivery company pays its drivers a fixed fee for each delivery made that day. The company deducts a daily fee for the use of the company's delivery truck.

Answer:
11 must be the fee for each delivery made
Step-by-step explanation:
p = 11d − 55
The y deduct the daily fee
deduct means subtract which means the daily fee is 55
d is the number of deliveries in one day
delivery company pays its drivers a fixed fee for each delivery made
Since d is the number of delivers, 11 must be the fee for each delivery made

You paid $600 for a new guitar. Your guitar costs $40 more than twice the cost of your friend's guitar. How much did your friend's guitar cost?
Cost of your guitar = $ 600
Let your friend's guitar's cost be = n
According to the question =
Your guitar costs $ 40 more than twice the cost of your friend's guitar which is n ,but your guitar's cost is $ 600.
So ,the linear equation for this will be =
= 2n+$40 = $600
= 2n = $600-$40
= 2n = $ 560
= n = $ 560/2
= n = $ 280
Thus ,the cost of your friend's guitar is $ 280.The cost of your friend's guitar is $280 by creating an equation based on the cost comparison to your own guitar, and then solving for the variable representing your friend's guitar's cost.
You paid $600 for a new guitar, which costs $40 more than twice the cost of your friend's guitar. To find the cost of your friend's guitar, let's denote the cost of your friend's guitar as x. According to the information given, your guitar's cost can be represented by the equation 2x + $40 = $600. Solving for x will give us the following steps:
Subtract $40 from both sides of the equation: 2x = $600 - $40.
This simplifies to 2x = $560.
Divide both sides by 2: x = $560 / 2.
Therefore, x equals $280.
The cost of your friend's guitar is $280.

Ryan went into town and bought some chicken feed that would last for the next 60 days. If he buys two 50 lbs bags for 5 chickens, how much does each chicken eat a day.
Answer:
3 pounds
Step-by-step explanation:
1. 50 + 50 = 100
2. 100 / 5 = 20
3. 60 / 20 = 3
Each chicken eats approximately 0.3333 pounds of feed per day, which is calculated by dividing the total feed (100 lbs) by the number of days (60) and then by the number of chickens (5).
To calculate how much chicken feed each chicken eats a day, we need to start by understanding the total amount of feed Ryan bought. He bought two 50 lbs bags, which is a total of 100 lbs of chicken feed. Since the feed needs to last 60 days for 5 chickens, we will divide the total feed by the number of days and then by the number of chickens.
First, we convert the weight of the feed into pounds (if it is not already in pounds). We know there are 100 lbs of feed in total.
Next, we divide the total weight of the feed by the number of days to find out how much feed is used per day:
100 lbs / 60 days = 1.6667 lbs per day (for all 5 chickens together).
Finally, we divide the daily feed consumption by the number of chickens to find out how much each chicken eats per day:
1.6667 lbs per day / 5 chickens = 0.3333 lbs per chicken per day.
Therefore, each chicken eats approximately 0.3333 pounds of feed a day.
x − 7 = 46 − 9(x + 7)
x =
Answer:
x=-1
Step-by-step explanation:
x − 7 = 46 − 9(x + 7)
distribute
x-7 = 46 - 9x -63
Combine like terms
x-7 = -9x-17
Add 9x to each sid
x-7+9x = -9x+9x -17
10x-7 = -17
Add 7 to each side
10x -7+7 = -17+7
10x = -10
10x/10 = -10/10
x = -1
Answer:
x = -1
Step-by-step explanation:
x − 7 = 46 − 9(x + 7)
x - 53 = -9x - 63
10x = -10
x = -1

What is the difference between joint, marginal, and conditional relative frequencies?
Answer:
The middle cells are the joint frequency numbers. When analyzing data in a two-way frequency table, you will be looking for joint relative frequency, which is the ratio of the frequency in a particular category and the total number of data values. The purple cells on this table are all joint frequency numbers.
The numbers in the column on the very right and on the row on the very bottom are the marginal frequency numbers. When analyzing data in a two-way frequency table, you will be looking for marginal relative frequency, which is the ratio of the sum of the joint relative frequency in a row or column and the total number of data values.
Conditional relative frequency numbers are the ratio of a joint relative frequency and related marginal relative frequency.
