A flower pot’s base has six sides that are all the same length. Each side measures

units. The base’s perimeter is 78 units. what is the value of x?

Answers

Since we know there are 6 sides and each side has the length of x-6, we set up this equation and solve:

6(x-6)=78

x-6=13

x=19

So the value of x is 19, which means each side has a length of 13 units.

Convert 13200 feet into miles

Answers

Answer:

2.5 miles

Step-by-step explanation:

to do this, you must know that there is 5280 feet in one mile.

then divide 5280 feet into 13200

13200 ÷ 5280 = 2.5

13200 feet can be converted to miles by dividing the length in feet by the conversion factor of 5280, which represents the number of feet in a mile.

To convert feet to miles,

divide the length in feet by the conversion factor of 5280, as there are 5280 feet in a mile. By dividing 13200 feet by 5280,  the results in 2.5 miles. This means that 13200 feet is equal to 2.5 miles in length.

To convert 13200 feet to miles, divide 13200 by 5280.

[tex]13200 / 5280 = 2.5[/tex] miles.

13200 feet is equivalent to 2.5 miles

Therefore, 13200 feet is equivalent to 2.5 miles by dividing the length in feet by the conversion factor of 5280, which represents the number of feet in a mile.

Which expression is equivalent to 210d2 - 63d

Answers

Answer:

21d (10d - 3)

Step-by-step explanation:

Factor 21d out of 210d² - 63d

I don't know if this answered your question correctly, but that is how I would solve it.

The expression is equivalent to 210d² - 63d is  21d( 10d - 3).

What is Expression?

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.

Given:

Expression: 210d² - 63d

now, factorizing each term of expression

210d² = 2 x 3 x 5 x 7 x  d x d

-63d = -3 x 3 x 3 x d

So, 210d² - 63d

= (2 x 3 x 5 x 7 x  d x d) - (3 x 3 x 7 x d).

= 21d (2 x 5 x d - 3 )

= 21d( 10d - 3)

Hence, the equivalent expression is 21d( 10d - 3).

What are the coordinates of its image, J'KL, if this
triangle is dilated by a factor of 5 with respect to the
origin?

Answers

Answer:

[tex]J'(-15,10)\\\\K'(15,10)\\\\L'(0,-20)[/tex]

Step-by-step explanation:

For this exercise you must remember that the original figure (before a transformation) is called "Pre-Image" and the one obtained after the transformation is called "Image".

 Dilation is defined as a transformation in which the Image and the Pre-Image have the same shape, but different sizes.

If a figure is dilated by a scale factor "k" with respect to the origin, the rule is:

[tex](x,y)[/tex] → [tex](kx,ky)[/tex]

In this case, the vertices of the triangle JKL (the Pre-Image) are:

[tex]J(-3.2)\\\\K(3,2)\\\\L(0,-4)[/tex]

Knowing that the scale factor is:

[tex]k=5[/tex]

You get that the vertices of the triangle J'K'L' (Image), are:

[tex]J'=(5(-3),5(2))=(-15,10)\\\\K'=(5(3),5(2))=(15,10)\\\\L'=(5(0),5(-4))=(0,-20)[/tex]

Alan, Brady and Matt shared 740 marbles. Alan has 20 fewer marbles than Brady and 120 fewer marbles than Matt. How many marbles did Alan have?

Step-by-step explanation:

[tex]Let\ Alan\ have\ =x\ marbles\\Brady\ have = (x+20)\ marbles\\Matt\ have = . (x+120)\ marbles\\\\Total\ marbles = 740\\x+(x+20)+(x+120)=740\\x+x+20+x+120=740\\3x+140=740\\3x=740-140\\3x=600[/tex]

Dividing [tex]3[/tex] both sides.

[tex]\frac{3x}{3}=\frac{600}{3}\\\\x=200[/tex]

Final answer:

We solve the problem by setting up a linear equation based on the information given. We solve it to find that Brady has 260 marbles and then deduct or add from this number to find the number of marbles for Alan and Matt. Our answer is that Alan has 240 marbles.

Explanation:

This problem involves solving linear equations in order to find the number of marbles each person has. Firstly, we need to represent each person's marbles in terms of the other person's marbles as given in the question.

Let's say Brady has 'b' marbles. From the problem, we deduce that Alan has 'b-20' marbles (20 less than Brady). We can also deduce that Matt has 'b-20+120' marbles (120 more than Alan).

Given that the total number of marbles is 740, we can set up the equation b + (b - 20) + (b - 20 + 120) = 740. Solving this linear equation, we get b = 260. Then, substituting b in the expressions for Alan and Matt will give us the number of marbles for each person, implying Alan has 260 - 20 = 240 marbles.

Simon makes 30 cakes he gives 1/5 of the cakes to Sali. He gives 10 percent of the 30 cakes to Jane what fraction of the 30 cakes does he have left?

Answers

Answer:

Step-by-step explanation:

0.1 = [tex]\frac{1}{10}[/tex]

1/5

30 × 1/10 = 3

30 × 1/5 = 6

6+3 = 9

30 - 9 = 21

21/30 simplified = 7/10

Answer:

7/10

Step-by-step explanation:

Total number of cakes made by Simon = 30 cakes.

Number of cakes gave to Sali =

1/5 Of total cakes = 1/5 x 30 = 6 cakes.

Number of the cakes gave to Jane = 10% of 30 cakes

10/100 as a decimal 0.10.

10% of 30 cakes = 0.10 times

30 = 3 cakes.

Total number of cakes left = Total cakes made - Cakes gave to Sali - Cakes gave to Jane

30-6-3 = 21

21 cakes left.

If A and B are independent events, P(A and B) =​

Answers

Answer:

If A and B are independent events, P(A and B) =​ P (A) * P (B)

Step-by-step explanation:

Let's recall that independent events means that when one event occurs, it has no impact or influence on the probability of another event occurring. Here’s an example. Let’s say that we have two events, A and B.  

Event A : it rains in Seattle

Event B : the Super Bowl match is cancelled in Miami

The two events are independent; if it rains in Seattle, this will have no impact on the probability that the Super Bowl match is cancelled in Miami. Raining in Seattle and the cancellation of the Super Bowl are independent events, therefore:

P(A and B) =​ P (A) * P (B)
