write x≤58 in interval notation.

Answers

Answer 1

The x ≤ 58 in interval notation = (-∞, 58]

In this question, we have been given an inequality  x ≤ 58

We need to write given inequality in interval notation form.

We know that, an interval notation a way to describe a subset of real numbers by the numbers that bound them.

If we draw given inequality on the number line, then it would be as shown below.

x ≤ 58 represents that, x takes all values which are less than or equal to 58.

So, the interval notation would be (-∞, 58]

Therefore, the x ≤ 58 in interval notation = (-∞, 58]

an envelope contains eight bills: two $ 1 bills, two $ 5 bills, two $ 10 bills, and two $ 20 bills. two bills are drawn at random without replacement. what is the probability that their sum is $ 20 or more? (a) 1 4 (b) 2 5 (c) 3 7 (d) 1 2 (e) 2 3

Answers

Probability is nothing but the ratio of favorable cases to all possible cases or in simple terms it is the ratio of sample set to all set

We are required to find all the cases in which sum of any two bills is 20$ or more

The total number of bills are two $ 1 bills, two $ 5 bills, two $ 10 bills, and two $ 20 bills.

The total case of drawing any two bills will be =

2 for $ 1 bill x two for 5$ bill x two for 10$ bill x two 20$ bills

=2 x 2x2x2 =16

Hence 16 ways in which two bills can be drawn at random

Cases in which bill can be greater than 20$= (1,20)(20,1)(5,20)(20,5)(10,10)(20,10)(10,20) (20,20)= 8 cases

Hence, total number of possible outcomes = 8

Hence the probability of bill to be 20$ or more= favorable outcome/total outcome

=8/16 =1/2

Hence the probability is 1/2

∵AB⊥XY ∴BX=BY
∵XY=3cm ∴BX= ½XY=1.5cm
Let the radius be r cm.
then, OX=OY=OA=r cm
∵AB=3.5cm ∴OB=3.5cm-r cm
∵AB⊥XY ∴OB²+BX²=OX²
∴(3.5-r)²+1.5²=r² ∴r=29/14
So the answer is 29/14 (2.1).

Answer:

2.1 cm (nearest tenth)

Step-by-step explanation:

The radius (r) of a circle is the distance between its center and its circumference.  Therefore, from inspection of the given circle:

⇒ r = OX = OY = OA

Given:

AB = 3.5 cmOA = r

⇒ AB = OA + OB

⇒ 3.5 = r + OB

⇒ OB = 3.5 - r

As OX = OY and AB is perpendicular to XY then XB = BY.

As XY = 3 cm:

⇒ XB = BY = 1.5 cm

Therefore, for ΔOBX:

Leg a = OB = (3.5 - r) cmLeg b = XB = 1.5 cmHypotenuse = OX = r cm

Pythagoras Theorem

[tex]a^2+b^2=c^2[/tex]

where:

a and b are the legs of the right triangle.c is the hypotenuse (longest side) of the right triangle.

Use Pythagoras Theorem and the defined sides of ΔOBX to find r:

[tex]\implies OB^2+XB^2=OX^2[/tex]

[tex]\implies (3.5-r)^2+1.5^2=r^2[/tex]

[tex]\implies 12.25-7r+r^2+2.25=r^2[/tex]

[tex]\implies 14.5-7r+r^2=r^2[/tex]

[tex]\implies 14.5-7r+r^2-r^2=r^2-r^2[/tex]

[tex]\implies 14.5-7r=0[/tex]

[tex]\implies 14.5=7r[/tex]

[tex]\implies 7r=14.5[/tex]

[tex]\implies \dfrac{7r}{7}=\dfrac{14.5}{7}[/tex]

[tex]\implies r=2.07142857...\: \sf cm[/tex]

Therefore, the radius of the circle is 2.1 cm (nearest tenth).

A group of friends wants to go to the amusement park. They have $235.75 to spend on parking and admission. Parking is $6.25, and tickets cost $25.50 per person, including tax. Write and solve an equation which can be used to determine pp, the number of people who can go to the amusement park.

Answers

Answer:

The equation for the number of people is 25.50x + 6.25 = 235.75 and the number of people who can go to the amusement park are 9.

Step-by-step explanation:

We have,

Spend on parking and admission = $235.75  

Spend on parking  = $6.25

Cost of ticket per person = $25.50

Let number of number of people = x

Now,

According to the question;

25.50x + 6.25 = 235.75

So, this the equation for number of number of people.

Now,

25.50x + 6.25 = 235.75

25.50x = 229.50

x = 9

So, number of number of people is 9, which we find out using the above mentioned equation.

Hence, we can say that the equation for the number of people is 25.50x + 6.25 = 235.75 and the number of people who can go to the amusement park are 9.

The number of people who can go to the amusement park is 9 they have $235.75 to spend on parking and admission. Parking is $6.25.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A group of friends wants to go to the amusement park. They have $235.75 to spend on parking and admission.

Parking is $6.25, and tickets cost $25.50 per person, including tax.

Let x be the number of people

6.25 + 25.50x = 235.75

25.50x = 235.75 - 6.25

25.50x = 229.5

x = 9

Thus, the number of people who can go to the amusement park is 9 they have $235.75 to spend on parking and admission. Parking is $6.25.

The volume of a cuboid having health is double of the height and length is triple of the height is 1296 cm ³ find the area of base.​

Answers

The area of the base is 216 cm².

The volume of a cuboid is 1296 cm³.

The breadth of the cuboid is double the height of the cuboid and the length of the cuboid is triple the height of the cuboid.

Let the length, breadth, and height of the cuboid be l, b, and h respectively.

Then,

l = 3(h)

b = 2(h)

The volume of a cuboid is given as:

V = l × b × h

1296 = 3(h) × 2(h) × h

1296 = 6 × h³

h³ = 1296 / 6

h³ = 216

h = ∛216

h = ∛(6)³

h = 6 cm

Therefore, the length of the b is l = 3(h) = 3 × 6 = 18 cm

The breadth of the cuboid will be:

b = 2(h)

b = 2 × 6

b = 18 cm

Now the volume of the cuboid is also given as:

Step-by-step explanation:

40 = -7 + 47v

47 = 47v

1 = v

Answer:

v = 1

Step-by-step explanation:

Let's solve the problem,

→ 8(5 - 6v) = -7 - v

→ 40 - 48v = -7 - v

→ 40 + 7 = -v + 48v

→ 47v = 47

Find the measures of the angle, its complement, and its suplement if three times the measure of a suplement of an angle is eight times the measure of a complement of the angle.

Answers

The angle, its complement, and its supplement are 36, 54 and 144 degrees respectively

Supplementary and complementary angles

The sum of complementary angles s 90 degrees while that of supplementary angles is 180 degrees.

Let the complement of an angle be 90 -x and its supplement be 180 -x

If three times the measure of a supplement of an angle is eight times the measure of a complement of the angle, then;

3(180-x) = 8(90-x)

Expand

540-3x = 730 - 8x

540-720 = -8x + 3x

180 = 5x

x = 180/5

x = 36 degrees

Complement  = 90 - 36 = 54degrees

[tex]2(p+w)[/tex] means, the plane speed, plus the windspeed, will take 2 hours to travel 450 KM. The reason we add the plane speed and the windspeed is because we have a tailwind instead of a headwind, the wind is pushing us forward, adding to the planes speed.

[tex]3(p-w)[/tex] means, the plane speed, minus the windspeed, will take 3 hours to travel 450 KM. We subtract the wind speed from the plan speed because the wind is a headwind, it's pushing us backwards, taking away from the planes speed.

• The unitary technique can be used to determine how many kilometres can be covered with 2 litres of gasoline, for instance, if a car goes 80 km on 6 l of fuel.

He washed 4 dishes in 2 minutes, thus we need to calculate how long it would take Rick to wash 6 plates. 4 plates, according to the rule, equals 2 minutes. Applying the unitary approach 1 plate in 2/4 of a minute 1 plate Equals 12 minute. 3 minutes equals 6 plates (12 times 6.6 plates).

The equations are given below.

−6x − 6y = −42      ...1

−x + 2y = 8            ...2

From equation 2, we have

x = 2y − 8

Put the value of x in equation 1, then we have
