Answer:

Step-by-step explanation:

diameter = 4.275"

r = 4.275 ÷ 2 = 2.1375"

Area of circle = πr²

                      = 3.14 * 2.1375 * 2.1375

                      = 14.3463

                     ≈ 14.3 in²

I'm guessing you are wanting to expand the expression?

[tex](7+x)^2=(7+x)(7+x)=(7)(7)+(7)(x)+(x)(7)+(x)(x)=49+7x+7x+x^2=x^2+14x+49[/tex]

Answer:

3y ≤ 1/2x

Step-by-step explanation:

please give brainliest!!

3 times y is less than or equal to half of x can be written as 3y ≤ x/2 or x ≥ 6y.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given that,

three times y is less than or equal to half of x can be written.

Three times y means that 3 is multiplied to y.

Half of x means that x is multiplied to 1/2.

This is an inequality expression.

We can write it as,

3y less than or equal to x/2.

3y ≤ x/2

Multiplying both sides by 2,

6y ≤ x

or x ≥ 6y

Hence the inequality expression is x ≥ 6y.

Answer:

4 sessions.

Step-by-step explanation:

He starts with 10 minutes practiced and has to finish his quota in 20 minute sessions, so we can represent that with the equation 90=20x+10. Then solve for x.

90=20x+10

Subtract 10

80=20x

Divide by 20

x=4

It would take 4 sessions.

Answer:

1 10 min session + x 20 min sessions = 90 min

10+20x=90

Step-by-step explanation:

To find the median, first, arrange the numbers from smallest to greatest. We have 18, 18, 22, 22. Next, find the number in the center. In this case, there are two numbers in the middle and it doesn't easily fall under one number. In this case, find the average of the two numbers. We have (18+22)/2 = 20. Therefore, the median of 18, 18, 22, 22 is 20.

Answer:

33

Step-by-step explanation:

Using the Intersecting Chords Theorem

For any two Intersecting Chords --->  UC*CW=TC*CV

By Substituting --->  12(2x+5)=14(2x+2)

By Expanding   --->  24x+60=28x+28

Then --> 28x-24x=60-28

Then --> 4x=32

So x=32/4=8

Now to get UW,,  UW=UC+CW=12+(2x+5)=2x+17

By Substituting by x=8

UW=2x+17=2*8+17=33

When it is asking you to solve a system of equations, it means that it wants you to find the value of the variables, in this case, x and y.

3x + 2y = 1  -- equation 1

y = x - 12 -- equation 2

Put (equation 2)'s value of y into (equation 1)

3x + 2(x-12) = 1

3x + 2x - 24 = 1

5x - 24 = 1

5x = 25

x = 5 -- equation 3

Put (equation 3)'s values of x into (equation 2)

y = 5 - 12 = -7

Thus the solutions are x = 5 and y = -7 and we have solved the system of equations.

The chords from the center of the circle will be 5 cm. Apply pythogorous to find the distance of chords from the center of the circle.

It is a point locus drawn equidistant from the center. The radius of the circle is the distance from the center to the circumference.

Given data;

Diameter,d=26 cm

Chord, PQ, = 24 cm

P is the chord from the center of the circle

All the given dimensions shown in the digrame are in the centimeter.

The chords from the center of the circle are found by the pythogorous theorem;

From Δ DCB

The value of the side p is;

h²=p²+b²

13²=p²+12²

169=p²+144

p=5 cm

Hence, the chords from the center of the circle will be 5 cm.

Step-by-step explanation:

Exponent of x = 6

Exponent of y = 2

Degree of the monomial = 6 + 2 = 8

Answer:

slope=0

Step-by-step explanation:

The required slope of the line is zero which implies that the given line is parallel to the x-axis.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

here,
The slope of the line that passes through the points (−10,−8) and (−9,−8) is given as,

m = (y₂ - y₁) /  (x₂ - x₁)

Substitute values in the above equation,
m = -8 + 8 / -9 +10
m = 0

Thus, the required slope of the line is zero which implies that the given line is parallel to the x-axis.

Answer:

x = 10

y = 42

Step-by-step explanation:

The sum of a number and two times a smaller number is 62

2x+y=62

so y=62−2x

Three times the bigger number exceeds the smaller number by 116

x+116=3y

substitute for y:

x+116=3(62−2x)

x+6x=186−116

7x=70

x=10

3y=10+116=126

#y = 126/3 = 42

Inequalities is a mathematic expression that do not present equalitiy between both sides. It is represented by symbols: <, ≤, > and ≥.

For solving this exercise, firstly, you should solve the inequalities identified by letters: H, W, M, Y and C. After that, you should relate yours anwers with the options given for the exercise.

                       [tex]-11x-4 > -15\\ \\ -11x > -15+4\\ \\ -11x > -11\; *(-1)\\ \\ 11x < 11\\ \\ x < 1[/tex]

Therefore, you should connect H with x<1.

Therefore, you should connect W with x>-2.

                       [tex]3+x\leq -9\\ \\ x\leq -9-3\\ \\ x\leq -12[/tex]

Therefore, you should connect M with x≤-12.

                       [tex]-7x+7\leq -56\\ \\-7x\leq -56-7\\ \\ -7x\leq -63\\ \\ -7x\leq -63\; *(-1)\\ \\ 7x\geq 63\\ \\ x\geq \frac{63}{7} \\ \\ x\geq 9[/tex]

Therefore, you should connect Y with x≥9.

The solution of inequality shows that the range is x >8.

The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined.

While the domain is related to the values ​​of x, the range is related to the possible values ​​of y that the function can have.

Inequality is a mathematical expression that does not present equality between both sides. It is represented by symbols: <, ≤, > and ≥.

For solving this question, you should convert the text of the problem into an algebraic expression. Consequently, you will have:

Step-by-step explanation:

Think of it as a percentage. 43% is [tex]\frac{43}{100}[/tex] , but it is also 0.43. Any number over 100 will be put into a similar decimal format ([tex]\frac{12}{100}[/tex] = 0.12  and [tex]\frac{4}{100}[/tex] = 0.04)

The fraction with a denominator of 100 is equivalent to 0.43 is,

[tex]\frac{43}{100}[/tex].

Here,

We have to find fraction with a denominator of 100 is equivalent to 0.43.

What is Fraction?

A fraction is used to represent the portion/part of the whole thing.

Now,

Let a fraction with a denominator of 100 is [tex]\frac{x}{100}[/tex].

And, its equivalent to 0.43.

Hence,
