Answer:

x=3 and y=4

Step-by-step explanation:

x+y=7;x+2y=11

Step: Solvex+y=7for x:

x+y=7

x+y+−y=7+−y(Add -y to both sides)

x=−y+7

Step: Substitute−y+7forxinx+2y=11:

x+2y=11

−y+7+2y=11

y+7=11(Simplify both sides of the equation)

y+7+−7=11+−7(Add -7 to both sides)

y=4

Step: Substitute4foryinx=−y+7:

x=−y+7

x=−4+7

x=3(Simplify both sides of the equation)

Answer:

x=3 and y=4

Answer:

a = -2  

Step-by-step explanation:

Ok, so for parallel lines you need to make slopes for both the lines equal. So for line y = x + 4 the slope is 1. (slope is the coefficent infront of the x value while in y=mx+b form. To make the other line have a slope of 1 a needs to be a number as so that 2a+5 = 1

2a+5 = 1

2a = 1 - 5

a = -4/2

a = -2

Answer:

y=8.1

Step-by-step explanation:

Comparing to the standard equation, the parabola with a vertex at (-2,0) is given by:

y = (x + 2)²

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

In this problem, we have that h = -2 and k = 0, and all the options have leading coefficient a = 1, hence the equation is:

y = (x + 2)²

Answer:

104

Step-by-step explanation:

There are two ways to do it, though we need to know how it is affected.

20+6=26

26+6=32

32+6=38

38+6=44

Thus, you are adding 6 for each term.

1. You do it manually...(yes.)

I'll number it one by one

1.20

2.26

3.32

4.38

5.44

6.50

7.56

8.62

9.68

10.74

11.80

12.86

13.92

14.98

15.104

The 15th term is 104.

2. This method is easier. As shown above, there is a pattern. We can apply it using this formula:
20+6(n-1)

You can get this formula from the facts that:
-you start off with an additional added 8

-you add 6 every time

-if we do it 6n then it would be incorrect, with an extra 6 for each

-the formula is correct; you can test it for terms 2,3,4,5 like this:

20+6=26

20+2x6=32

20+3x6=38

20+4x6=44

To find the 15th term, you can:

20+14x6=20+84=104.

Option C) 301 ft³ is the correct answer.

Hence, the closest to the amount of fuel the cylindrical tank can hold is 301 ft³.

This question is incomplete, the missing image is uplaoded along this answer.

Volume simply the amount of space enclosed within a container.

The volume of a cylinder can be expressed as;

V = πr²h

Where r is the radius of the base of the cylinder, h is its height and π is pi ( π = 3.14)

Given the data in the question;

To determine the closest to the amount of fuel the tank can hold, we substitute our given values into the expression above.

V = πr²h

V = 3.14 × (4ft)² × 6ft

V = 3.14 × 16ft² × 6ft

V = 301.44ft³

V = 301 ft³

Option C) 301 ft³ is the correct answer.

Hence, the closest to the amount of fuel the cylindrical tank can hold is 301 ft³.

Answer:

Step-by-step explanation:

The values of angles are written below,

a° = 121°

b° = 53°

c° = 87°

d° = 72°

The Inscribed Angle Theorem: This theorem states that the measure of an inscribed angle in a circle is equal to half the measure of the intercepted arc.

In other words, if an angle is formed by two intersecting chords in a circle, the measure of the angle is equal to half the sum of the measures of the arcs intercepted by the angle.

The values of angles are calculated as,

a = (2 x 108 ) - 9 5

a = 121°

b = 360 - ( 121 + 95 + 91 )

b = 53°

c = (121 + 53 ) / 2

c = 87°

d = ( 91 + 53 ) /2

d = 72°

Therefore, the values are a = 121°, b = 53°, c = 87°, and d = 72°.

Using it's concept, it is found that the probability that an ID code does not contain the letter I is given by:

A. 0.9246

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Considering that for each letter there are 26 possible outcomes and for each digit there are 10 possible outcomes, the total number of outcomes is given by:

T = 26 x 26 x 10 x 10 x 10 x 10 = 6,760,000.

Without the letter "l", the desired number is given by:

D = 25 x 25 x 10 x 10 x 10 x 10 = 6,250,000.

Hence, the probability is given by:

p = 6,250,000/6,760,000 = 0.9246.

Answer:

32°

Step-by-step explanation:

Complementary angles sum to 90°

the complement of 58° is

90° - 58° = 32°

Complementary angles add up to [tex]\sf{90^\circ}[/tex].

In order to find the complement of the given angle, we should set up the following equation:-

(let n be the unknown angle)

[tex]\sf{n+58=90}[/tex]

Subtract 58 from both sides:-

[tex]\bigstar{\boxed{\pmb{n=32}}[/tex]

Hence, the complement of the angle is 32 degrees.

Step-by-step explanation:

hope it helps

The required simplified value of R is 2000, as of the given percentage.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Let the required value be R,
50% of R = 100
R = 100 / 50%
R = 100 / 0.50
R = 2000

Thus, the required value of R is given as 2000.
