The system of equations y=-2x+3 and y= x is graphed.What is the solution to the system of equations?

Answer:

Percent error is approx. 22%

Step-by-step explanation:

So to do this you need to know the formula for percent error, which is

percent error = l measured - theoretical / theoretical l * 100%

With this just plug in 18 (real) and 14 (measured).

percent error = l 14 - 18 / 18 l * 100%

percent error = l -4 / 18 l *100%

percent error = l -2/9 l *100%

You then do absolute value because the percent error must be positive not negative! So -2/9 becomes 2/9. You then divide 2/9 to get approx. 0.22... and you muliply by 100% to get 22%.

Step-by-step explanation:

Answer:

3. m∠1 = 106° ~ this is because ∠1 and ∠2 together make a straight line and are therefore supplementary, meaning added together, they equal 180° (so I did 180° - 74° = 106°)

4. m∠3 = 74° ~ again, it is supplementary to ∠1. It is also equal to ∠2

5. m∠8 = 114° ~ angles opposite of each other (like 1 and 4) are equal (as we know from question 4). From there, we can use the corresponding angle theorem, so we know 4 and 8 are congruent. (also you can just know 1 and 8 are congruent by using the opposite exterior angles theorem)

6. m∠6 = 124° ~ using same-side interior angle theorem, they are supplementary angles (or the corresponding angles theorem mentioned above, make 4 congruent to 8, and 8 is supplementary to 6)

7. m∠7 = 96° ~ using same side exterior angle theorem, these angles are supplementary

8. m∠2 = 64° ~ again, same side exterior angle theorem

Answer:

A) Any straight line segment can be extended indefinitely.

C) A straight line segment can be drawn between any two points.

D) All right angles are equal.

Answer:

Scale Factor= 1:150

Step-by-step explanation:

So if 2cm on the map represents 3 meters,

you could write that as a fraction and at meters.

[tex] \frac{0.02}{3} [/tex]

which you could multiply by

[tex] \frac{50}{50} [/tex]

to get the fraction

[tex] \frac{1}{150} [/tex]

That's the scale factor 1:50

Hence, answer:

The scale factor is 1:150

y = total snow accumulated

x = hours

the ground has 0.2 inches of snow before the data starts

y = 1.5x+0.2

0 hours = x = 0, so y = 0.2 inches

after 9 hours, we predict that 13.7 inches of snow will have accumulated

y = 1.5(9)+0.2 = 13.7

Given that,

Natasha can hit a bullseye about 95% of the time

we've to find the number of throws will she

need in order for her to hit 76 bullseyes

for that, we'll divide 76 by 95%

[tex] \huge \rightarrow \: 76 \div \frac{95}{100} = \frac{76}{\frac{95}{100} } \\ [/tex]

[tex] \huge \rightarrow76 \times \frac{100}{95} [/tex]

[tex] \huge \rightarrow80[/tex]

Hence, she need 80 bullseye in order for her to hit 76 bullseyes

Answer:

Step-by-step explanation:

P(hit a bulleye) = 95% = 0.95

P(hit 2x bulleyes) = 0.95*0.95

P(hit 76x bulleyes) = 0.95^76

= 0.02

So she will hit 76 bulleyes on average every 1/0.02 = 50 times.

Total number of throws = 50 x  76

= 3800

Answer:

Six.

Step-by-step explanation:

6×2.65 we can round to 6×2.5=$15 the next smallest ans is 12, 12 is double of 6 so the ans would be double (30), 30 is a lot larger than 20 so we can safely assume that 6 is correct.

Answer: the bottle of apple juice is 88% water

Answer:

In explanation

Step-by-step explanation:

Ummm... could there maybe be a picture but let me see let me try to guess.

You could turn this problem into a fraction.

Is the water 10% of the apple juice=1/10

If the water was 1/3 it would=33.333%

If it were 1/4 it would be 25%

if it were 1/5 it would be 20%

If it was 75% water it would be 3/4 or 50% is half of something so like 3/6

9/18 15/30 or more.

Is there a picture I could see to help you in comment s or something i can use to answer or does one of the answers above tell you something.

Hope this helps and remember show me more of the question please so  can help you have a great day

Using the combination formula, it is found that there are 129 different combinations.

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this problem, combinations of 1, 2 or 3 pieces from a set of 9 are taken, hence:

[tex]C_{9,1} = \frac{9!}{1!8!} = 9[/tex]

[tex]C_{9,2} = \frac{9!}{2!7!} = 36[/tex]

[tex]C_{9,3} = \frac{9!}{3!6!} = 84[/tex]

Answer:

Lowest angle of elevation is 20.8

Step-by-step explanation:

If he is in the middle of the field, then the 100 value is split in half.

Then, you do 20-1 because of the height of the telescope.

So now, to solve:

tanx= 19/50 (opposite over adjacent)

x= tan^-1 times (19/50)

19 devided by 50= 0.38

then do 0.38 tan^-1

and round.

Therefore the answer is 20.8

Answer:

B = (4, 0)

Step-by-step explanation:

We are told that  [tex]l_2[/tex]  intersects the x-axis at B.

To determine where  [tex]l_2[/tex]  intersects the x-axis, set y to zero in the [tex]l_2[/tex]  equation and solve for x:

[tex]\implies 0+x=4[/tex]

[tex]\implies x=4[/tex]

Therefore, B is (4, 0)

Answer:

(4,0)

Step-by-step explanation:

coordinate B lies on the equation y + x = 4

y = 0 and x is unknown, so putting this in the equation:

y + x = 4

0 + x = 4

x = 4

Answer:

Let c be the common factor between Jill and Kelly’s money. Then:

4n-156 / 5n-156=8/11

So:

44n-1716=40n-1248

4n=468

n=117

Jill had 4n, or $468 to begin with

Kelly had 5n, or $585 to begin with ………..

Answer:

Step-by-step explanation:

x=Jill's money

y=Kelly's money

x/y=4/5

(x-156)/(y-156)=8/11

x/y=4/5 -------->5x=4y --------->y=5x/4

cross multiply with the above proportion

11(x-156)=8(y-156)

11x-1716=8y-1248

substitute y=5x/4

11x-1716=8(5x/4)-1248

11x-1716=10x-1248

11x-10x=1716-1248

x=$468 for Jill  (answer)

x/y=4/5

468/y=4/5

multiply 4 by 117 to get 468

multiply 5 by 117 to get 585

y=$585 for Kelly (answer)   (or cross multiply to find y)

11pi/4

=======================================================

Explanation:

The angles shown add to: 120+45+30 = 195 degrees.

The remaining bit needed to get to a full 360 degree circle is 360-195 = 165 degrees, which is the measure of central angle AFD.

This means the arc AED is 165/360 of the full circle perimeter or circumference.

The fraction 165/360 reduces to 11/24 after dividing both parts by the GCF 15

So we can say that the length of arc AED is exactly 11/24 of the full circumference.

-----------------

The length FB is 3 units (radius), so EB is 6 units (diameter)

This leads to,

C = circumference

C = pi*diameter

C = pi*6

C = 6pi

That's the full circumference, but we only want 11/24 of it to get arc AED.

arc AED = (11/24)*(full circumference)

arc AED = (11/24)*(6pi)

arc AED = 11pi/4 which is choice D

I'm assuming choice D says 11pi/4

[tex]2\frac{1}{3}[/tex]

Step-by-step explanation:

The improper fraction was 7/3 put that into a mixed number it it 2 1/3.

Answer:

y = 64 / 7

Step-by-step explanation:

We can use Similar Triangle Theorem to find y.

The ratio of the "long leg to hypotenuse" of the large triangle is equal to the ratio of the "long leg to hypotenuse" of the medium triangle.

Therefore,

⇒ 8 : y = 7 : 8

Writing as fractions:

⇒ 8 / y = 7 / 8

Cross multiply:

⇒ 8 × 8 = 7 × y

⇒ 64 = 7y

divide both sides by 7

⇒ y = 64 / 7

Answer:

Step-by-step explanation:

8 : y = 7 : 8

8 / y = 7 / 8

8 × 8 = 7 × y

64 = 7y

y = 64 / 7

y = 9.14
