1. yes ±4

2. no, it's between 9 and 4

3. no, it's between 25 and 9

4. yes ±7

5. yes ±11

6. no, it's between 81 and 64

~Step-by-step explanation~
_____________________________________

ok I'll walk you through this
1. x²=16
x = ±4 because (-4)(-4) is 16 and (4)(4) is also 16
4. x²=49
x=±7 because (-7)(-7)=49 and (7)(7) is also 49
5. x²=121
x=±11 because (-11)(-11)=121 and (11)(11)=121.

3x+y=3 can you pleas help me find x and y

Answers

Answer:

x= 2, y= -3

Step-by-step explanation:

Given two equations, we can solve them by either substitution or elimination method. Let's solve by substitution!

x -y= 5

Rewrite this equation such that one of the variable is the subject of formula, so that we can substitute this equation into the second.

x= y +5 -----(1)

3x +y= 3 -----(2)

Substitute (1) into (2):

3(y +5) +y= 3

Expand:

3y +15 +y= 3

4y= 3 -15

4y= -12

y= -12 ÷4

y= -3

Substitute y= -3 into (1):

x= -3 +5

x= 2

what least number should 27648 be divided so that the quotient will be a cube number

Answers

Method A - write in prime factor form
27648 = 2^10 x 3^3 = 2 x 2^9 x 3^3 = 2x (2^3 x 3)^3 = 2 x 24^3
So if 27648 is divided by 2 the quotient is a cube number

Method B - test the list of cubic numbers to find the biggest factor of 27648
The cubic factors are 1, 8, 27, 64, 216, 512, 729, 1728, 4086, 5832, 13824

Method C - divide by factors starting with 1 until quotient is a cube
27648 / 1 = 27648 fail
27648 / 2 = 13824 = 24^3 correct

A number is given three successive discounts of 20%, 25% and 20%; Three successive increases of 20%, 25% and 20% are made to the resulting number, resulting in a number that differs from the original by 408 units. Calculate the original number.

Answers

Answer:

3000

Step-by-step explanation:

The multiplier associated with each percentage change (p) is (1 +p). We can use this fact to relate the original number to the modified number.

discounted number

Let x represent the original number. Then the discounted number is ...

x(1 -20%)(1 -25%)(1 -20%) = x(0.8)(0.75)(0.8) = 0.48x

increased number

After those discounts, the increased number is ...

(0.48x)(1 +20%)(1 +25%)(1 +20%) = (0.48x)(1.2)(1.25)(1.2) = 0.864x

difference

The difference from the original is ...

x - 0.864x = 408

0.136x = 408 . . . . simplify

x = 3000 . . . . . . . divide by the coefficient of x

The original number was 3000.

Triangle ABC represents a triangular garden with side lengths AB= 10cm ,BC= 8cm and AC=15cm .

What is the smallest and largest angle of the garden?

Answers

Answer:

Largest angle is "B" and smallest angle is "A".

Step-by-step explanation:

Given ∆ABC

AB = 10 cm , BC = 8 cm , AC = 15 cm

Angle opposite to side AB is "C"

Angle opposite to side BC is "A"

Angle opposite to side AC is "B"

we know that the angle opposite to largest side is largest angle and smallest side is smallest angle.

Here,∆ABC largest side is AC and smallest side is BC.

Hence,largest angle is "B" and smallest angle is "A".

Grady's father is building a 15-meter fence with the start of the fence at coordinates (8,5) and the midpoint of the fence at coordinates
(3.5,-1). What are the coordinates of the other end of the fence

Answers

Using proportions, it is found that the coordinates of the other end of the fence are (-1,-7).

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The midpoint of a segment is the mean of the coordinates of the endpoints, hence:

[tex]3.5 = \frac{x + 8}{2}[/tex]

x + 8 = 7

x = -1.

[tex]-1 = \frac{y + 5}{2}[/tex]

y + 5 = -2.

y = -7.

The coordinates of the other end of the fence are (-1,-7).

A shipping box is in the shape of a rectangular prism. it has a volume of 9,000 in.3, and the dimensions of the base are 20 in. by 30 in. what is the height of the box? 15 in. 20 in. 300 in. 600 in.

Answers

The height of the shipping box in the shape of a rectangular prism is 15 inches

How to determine the height of the box?

The given parameters are:

Volume = 9000 cubic inches

Base dimensions = 20 inches by 30 inches

The height of the prism is then calculated using:

Height = Volume/Base Area

So, we have:

Height = 9000/(20 * 30)

Evaluate

Height = 15

Hence, the height of the shipping box in the shape of a rectangular prism is 15 inches
