Answer:

The greatest possible length is 900 cm

Step-by-step explanation:

Here, we want to calculate the greatest possible length of 12 of those rods

Firstly, we assume that the rods have a length of 75 cm

This will give the greatest possible length of each of the rods

So the possible length of 12 of these will be

12 * 75 = 900 cm

Answer:

t > -2

Step-by-step explanation:

Since the graph is not continuous at -2, thus it is not included!

Answer:

X: x=3-3/5y

Y: y=5-5/3x

Step-by-step explanation:

For X:

-3y on both sides will result in:

5x=15-3y

5x/5=15/5-3y/5 (divide 5 on both sides)

x=3-3/5y

For Y:

-5x on both sides will result in:

3y=15/3-5x/3 (divide 3 on both sides)

y=5-5/3x

please mark brainliest

Step-by-step explanation:

so why you are asking?????

Answer:

It is: (f(2) - f(0))/(2 - 0)

f(2) = 250(0.5)(2) = 250

f(0) = 250 (0.5)(0) = 0

So: (250 - 0)/(2 - 0) = 250/2 = 175

The average rate of change is 175.

Answer: the second one

Step-by-step explanation:

because [tex]-4^{4}[/tex]= -256

Answer:

2 3/20 metres

Step-by-step explanation:

Area of the rug = Length × width

Given

Area = 7 1/6 metres = 43/6 m

Length = 3 1/3 metres = 10/3 m

Required

Width

From the formula

A = LW

W = A/L

Substitute the given values

W = 43/6÷10/3

W = 43/6×3/10

W = 43/2 ×1/10

W = 43/20

W = 2 3/20 m

Hence the width of the rug is 2 3/20 metres

Answer:

32

Step-by-step explanation:

7 x 6 is 32 so u get that

Volume of cuboid =l×b×h

area of base of the cuboid =l×b

hence

volume of cuboid is = area of base × height

140=88×h

h=140÷88

h=5

Answer:

1/2

Step-by-step explanation:

Let the total pie be 2

She ate 1/6

Her brother ate 1/3

If she gave her Friend the remaining, the fraction of the amount her friend collected is expressed as:

1-(1/6+1/3)

= 1-((1+2)/6)

= 1-3/6

= 1 - 1/2

=1/2

Hence the fraction she gave her friend is 1/2

Answer:

Its an example  Unit rate becuase theres the #1 in it and its constant

Step-by-step explanation:

A rate is more like a ratio of 2 different number

3:6

or

9:18

When these are simplified you’ll get 1 in one of the 2 numbers but then it would be a unit rate

Rate= no #1

Unit rate= Defined as a number 1

Answer:

y=-6

Step-by-step explanation:

y=mx+b, b is the y-intercept, m is slope

slope (m)= rise/run

(-6--6)/(7-3)=

0/4=

0

So plug it in.

y=(0)x+b

y=b

But what is y?

Pick either coordinate and plug the y-value into the equation y=b.

Now you have -6=b

So the final equation is y=-6.

It doesn't matter what the x value is, it's going to be multiplied by 0, the y coordinate on this line will always be -6.

Alternatively, you can plot it out, both (7,-6) and (3,-6) have the same y coordinate, therefore you can immediately see that the slope=0 because it's just a horizontal line.

Answer:

$9.60 for 12 sandwiches

To solve the problem we will calculate the cost of 1 sandwich first.

The cost of 12 sandwiches is 9.6 Rands.

Given

15 sandwiches are sold for 12 Rand

We know the cost of 15 sandwiches is 12 Rand, therefore,

[tex]\text{Cost of 1 Sandwich} = \dfrac{\rm 12\ Rand}{\rm 15\ Sandwich}[/tex]

[tex]\text{Cost of 1 Sandwich} = \dfrac{12}{15} = 0.8\ \rm Rand/Sandwich[/tex]

The cost of 12sandwiches can be calculated using the cost of 1 sandwich,

[tex]\text{Cost of 12 Sandwiches} = \text{Cost of 1 sandwich} \times 12[/tex]

                              [tex]= 0.8 \times 12 = 9.6\ \rm Rand[/tex]

Hence, the cost of 12 sandwiches is 9.6 Rands.

Answer:

Step-by-step explanation:

a). [tex]\frac{5\pm\sqrt{-4}}{3}[/tex] = [tex]\frac{5}{3}\pm \frac{\sqrt{-4}}{3}[/tex]

Answer:

2704

Step-by-step explanation:

My probability math is a bit rusty, but here's my reasoning.

Assuming that it is a 1/26 chance someone has the same first inital as you (which isn't true, some initials are more prominent than others) and a 1/26 chance that somone has the same last inital as you (also not true) then it would be a 1/26 x 1/26 chance to find someone with the same first and last inital as you

To find 4 people in a room with the same inital would be 26 x 26 x 4, or 2704. If we are counting Olivia as a fifth person, then it would be 26 x 26 x 5, or 3380.

Answer:

10x+10

Step-by-step explanation:

distrubute 4(x+10)-30+6

subctract 4x+40-30+6

combine 10x+10

Answer:

4x + 1 is the simplified expression

Step-by-step explanation:

We have to use order of operations in order to solve. We basically need to simplify it with multiplication and addition.

The first step involves mulitplication and distribution property:

1) Do 1/2(4x + 2). If you use distribution property, it would be 1/2(4x) + 1/2(2)

2) Then use multiplication 1/2(4x) is 2x (since 4 multiplied by 1/2 is 2) and 1/2(2) is 1 (since 1/2 times 2 is 1).

Bow the expression is almost simplified as it is:

2x + 1 -(-2x)

The 2nd stop involves addition. First we have to know what -(-2x) means. Think of the negative sign on the outside as -1. This way it would be:

3) -1(-2x), and then do -1(-2) which is 2 since a negative times a negative is positive.

4) Now we know that -(-2x) is the same as: + 2x.

5) So the expression would be 2x + 1 + 2x. Combine like terms ( 2x and 2x) and you will get 4x + 1.

Answer:

a) 13%

b) 45%

c) 16%

Step-by-step explanation:

To calculate what percentage is one number (a) of another (b), you have to divide a by b and then multiply result by 100. In this case number of students with grade A is 4, total number of students is 31,  therefore 4/31 * 100 = 12.9%. Rounding it to the nearest percentage will give you 13.
