Answer:
x = 140
Step-by-step explanation:
Using the exterior angle rule ( an exterior angle of a triangle is equal to the opposite interior angles of a triangle )
x is the interior angle and the given angles ( 50 and 90 ) are the opposite interior angles
So
x = 50 + 90
50 + 90 = 140
x = 140
Note: there is a right angle ( indicated by the little square. A right angle has a measure of 90 degrees so that's where the 90 came from)

12 pints
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
Basically you need to use ratios using the gallons and pints
so for every 8 pints you get a gallon so the ratio would be 1:8 in the next number we have 1 and 1/2 we already found 1 gallon which is 8 then you need to find half of a gallon which is 8/2 or splitting the 8 in half which is 4. 8 pints (1 gallon) plus 4 pints (half a gallon) equals 12 pints. you can apply this rule for the next number we have 1 gallon which is 8 pints and we need to find 2 which would be 8 times 2 or 16 pints.
The cost of bottles of vitamins varies
directly with the number of vitamin
tablets in a bottle. A bottle of 50 vitamin
tablets costs $12. What is the cost in
dollars of a bottle of 75 vitamin tablets?
Answers
Answer:
find cost of one vitamin tablet first
50/12 = 4.2
therefore $4.2 is the cost for one tablet
now to find the cost of 75 vitamin tablets we just need to multiply the cost of one tablet with 75.
75*4.2=315
therefore the cost of a bottle of 75 vitamin tablets is $315

Answer:
Angle C
Step-by-step explanation:
By applying sine rule in the given triangle,
[tex]\frac{\text{sinB}}{CD}=\frac{\text{sinC}}{BD}=\frac{\text{sinD}}{BC}[/tex]
[tex]\frac{\text{sinB}}{\text{sinC}}=\frac{\text{CD}}{\text{BD}}[/tex]
Therefore, sides of the given triangle will be in the same ratio as the sine of the angles.
Since, BD > BC > CD
Therefore, Opposite angles of these sides will be in the same ratio.
∠C > ∠D > ∠B
Largest angle of the triangle is angle C.

ms. lorenz needs to rent a car for 3 days. she can choose from two plans. plan a costs $60 per day. plan b costs $30 per day plus $.40 for each mile she drives. ms lorenz decides that plan b will cost her less than plan a. write and solve an inequality to represent the number of miles, m, that ms. lorenz expects to drive. PLEASE HELP!!!
Answers
Answer:
distance driven < 300 miles.
Step-by-step explanation:
Plan A
She needs the car for 3 days.
1 day costs 60 dollars
3 days cost 60*3 = 180 So this is the maximum amount that she can spend
Plan B
She still needs the car for 3 days
1 day costs 20 dollars of the car does not move
3 days costs 3*20 = 60 dollars.
60 + 0.4m < 180 Subtract 60
0.4m < 180 - 60
0.4m < 120 Divide by 0.4
m < 120/ 0.4
m < 300
Answer
so she should drive less than 300 miles.
A piece of fabric 4 meters long is cut into two pieces. One piece is 1.25 meters long. How much longer is the second piece of fabric?
Answers
Answer:
1.5 meters
Step-by-step explanation:
the fabric is 4 meters long
first piece is 1.25 meters long
second piece will be (4-1.25)=2.75 meters long
therefore the second piece is (2.75-1.25) meters longer
Answer:
1.5 meters
Step-by-step explanation:
4 meters - 1.25 meters=2.75m is the length of the second one.
But when they ask how much longer , I think they want you to compare the two pieces meaning to get the answer you have to take 2.75m-1.25m=1.5m thats how much longer the 2nd fabric is longer than the other one.
hope am right

The graph of linear function f passes through the points (-8,-2) and (4,4). What is the x-intercept of f?
Answers
Answer:
2
Step-by-step explanation:
X= 2
just make a graph and you got the answer
.
The value of the x-intercept if f passes through the points (-8,-2) and (4,4), is -4 and the equation of the line is 2y -x = 4.
What is function?Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and co-domain, respectively.
Given:
The graph of linear function f passes through the points (-8,-2) and (4,4),
Calculate the equation of the line as shown below,
y - 4 = [4-(-2) / 4 - (-8)](x - 4)
y - 4 = 6 / 12 (x - 4)
y - 4 = 1/2 (x - 4)
2y - 8 = x - 4
2y -x = 4
Calculate the x-intercept by putting y = 0,
0 × 2 - x = 4
x = -4
Thus, the value of x is -4.

A store receives a shipment of 5,000 MP3 players. In a previous shipment of 5,000 MP3 players, 300 were
defective. A store clerk generates random numbers to simulate a random sample of this shipment. The
clerk lets the numbers 1 through 300 represent defective MP3 players, and the numbers 301 through
5,000 represent working MP3 players. The results are given.
638 430 240 3,932 4,477 670 3,059 13 3,144 3,844
Based on this sample, how many of the MP3 players might the clerk predict would be defective?
The manager would expect
defective players in the shipment.
Answers
The sample was 10 numbers.
4 of the numbers are less than 301.
So 4 out of 10 would be defective.
4/10 = 0.4 x 100 = 40%
He would expect 40% to be defective.
