Cubic Units

Step-by-step explanation:

Answer:

$5.29

Step-by-step explanation:

five quarters is 1.25. since we start with four dollars, that gives us 5.25, plus the 4 cents from the pennies, making 5.29.

Answer:

$5.29

Step-by-step explanation:

We have a solid 4 dollars to begin with so we will write $4.

Next we see that there are 5 quarters, each being 25 cents, we add this to 125 cents. We know that 100 cents is equal to a dollar so we add that to 4 and we have an excess 25 cents so we would write $4.25. We also have 4 pennies, each being 1 cent, we add that to $4.25 to get $4.29.

I hope this helps. Here is a reference

$1= 100 cents

Quarter= 25 cents

Dime= 10 cents

Nickel= 5 cents

Penny= 1 cent

Answer:

(-9/2t + 3) +( 7/4t + 33) = -11/4t + 36

5(2t + 1)+(-7t +28) = 3t+ 33

Step-by-step explanation

Those are the ones i could solve hope this helps!

1. Problem  

(-9/2t + 3) +( 7/4t + 33)

-9/2t + 7/4t

-18/4t +7/4t= -11/4t

3+ 33= 36

-11/4t + 36

2. Problem

5(2t + 1)+(-7t +28)

10t + 5 + ( -7t +28)

10t - 7t= 3t

5+ 38= 33

Step-by-step explanation:

The given quadratic equation is in standard form.

Explanation

We can only keep one of the digits: either the tens digit or the units digit. If we kept only the units digit, then we go from 39 to 9 which is a very steep drop. If we kept the tens digit then we go from 39 to 30

The 0 in the "30" is not significant. It's just a placeholder to help us tell 30 apart from simply 3. The drop from 39 to 30 is much smaller (compared to from 39 to 9). But you can probably see that it's even better to bump up to 40 instead, due to the smaller change.

In short, 39 rounds up to 40 when rounding to one significant digit.

Answer:

x>-1

Step-by-step explanation:

So, we want to isolate the variable which is X. To do so, we must add 4 on both sides.

x-4+4>-5+4

x>-1

Next comes the graphing:

This equation means that x can be all values that are LARGER THAN -1. The line would start from -1, but it wouldn't include negative one, and stretch all the way to positive infinity (to the right).

Answer:

x=2 would be your answer

Answer:

x = 2

Step-by-step explanation:

3(x - 3) = - 3

3x - 9 = - 3

3x - 9 + 9 = - 3 + 9

3x = 6

3x ÷ 3 = 6 ÷ 3

x = 2

Answer:

1/53

Step-by-step explanation:

There are 53 people, and you are 1 person who has a chance to be picked.

Answer:

d, 1/53

Step-by-step explanation:

Answer:

No mode.

Step-by-step explanation:

No mode.

None of the numbers repeat and since the mode is the most frequent number there isn't one.

Answer:

There is no mode

Step-by-step explanation:

Because none of the digits are duplicated.

Answer:

15. $232.50

16. $325.50

Step-by-step explanation:

15)108.50-46.50=62

7-3=4

62/4=15.5

15.5*15=232.5

16) 15.5*21=325.5

Answer:

A

Step-by-step explanation:

Given :

And we need to find the inverse of the given function. We can do it by Firstly Interchanging x and y.

So that ,

[tex]:\implies[/tex] f(x) = y

[tex]:\implies[/tex] y = ³√[ x - 9 ]

[tex]:\implies[/tex] x = ³√[ y - 9 ]

[tex]:\implies[/tex] x³ = y - 9

[tex]:\implies[/tex] y = x³ + 9

[tex]:\implies[/tex] f-¹(x) = x³ + 9

Hence option A is correct .

Answer:

50 km/hr

Step-by-step explanation:

D = RT

Time for first part of trip = 80/60 = 4/3 hr.

Time for second part of trip = 20/30 = 2/3 hr.

total time for entire trip = 4/3 + 2/3 = 6/3 = 2 hr.

Total distance = 100 km

Average rate of speed for entire trip = 100/2 = 50 km/hr

Answer:

1.2m

Step-by-step explanation:

1 meter = 100 cm

120cm * (1m/100cm)  = 1.2m

Answer:

2198 cm²

Step-by-step explanation:

Total surface area of a cylinder = 2πrh + 2πr²

Radius, r = diameter/2

= 20cm/2

= 10 cm

Height, h = 25 cm

Total surface area of a cylinder = 2πrh + 2πr²

= 2*3.14*10*25 + 2*3.14*10²

= 1,570 + 6.28*100

= 1,570 + 628

= 2198 cm²

Total surface area of a cylinder = 2,198 cm²

Answer:

the point of interception is where the graphs meets

in this case we will solve using substition method

x + 5y = 8 .... 1

-x + 2y = -1 .....2

solve for the equation

x = 8 - 5y ...... 3

solve the equation in equation 2

-x + 2y = -1

-(8-5y ) + 2y = -1

-8 +5y + 2y = -1

7y = -1 + 8

7y = 7

divided by 7 on both sides

y = 1

solve the value of y in equation 3

x = 8 - 5y

x = 8 - 5(1)

x = 8 -5

x = 3

the point of interception (3 ; 1)

Answer:

Ratio of heights: 3 : 2

Ratio of surface areas: 9 : 4

Ratio of volumes: 27 : 8

Step-by-step explanation:

Since both cuboids are proportional, then we must derive expressions for the ratios of heights, surface areas and volumes from the following identities:

Perimeter

[tex]p' = k_{p}\cdot p[/tex] (1)

Surface area

[tex]A'_{s} = k_{A_{s}}\cdot A_{s}[/tex] (2)

Volume

[tex]V' = k_{V}\cdot V[/tex] (3)

Where:

[tex]p[/tex], [tex]p'[/tex] - Perimeters of the small cuboid and the big cuboid, in inches.

[tex]A_{s}[/tex], [tex]A'_{s}[/tex] - Surface areas of the small cuboid and the big cuboid, in square inches.

[tex]V[/tex], [tex]V'[/tex] - Volumes of the small cuboid and the big cuboid, in cubic inches.

By means of geometry formulas we expand the system of equations below:

Perimeter

[tex]4\cdot (w' + h' + l') = k_{p}\cdot [4\cdot (w + h + l)][/tex]

[tex]4\cdot (k\cdot w'+ k\cdot h' + k\cdot l) = k_{p}\cdot [4\cdot (w+h+l)][/tex]

[tex]k_{p} = k[/tex]

Surface area

[tex]2\cdot (w'\cdot h' + l'\cdot w' + l' \cdot h') = k_{A_{s}}\cdot [2 \cdot(w\cdot h + l \cdot w + l\cdot h)][/tex]

[tex]2\cdot [(k\cdot w')\cdot (k\cdot h') + (k\cdot l)\cdot (k\cdot w) + (k\cdot l)\cdot (k\cdot h)] = k_{A_{s}}\cdot [2\cdot (w\cdot h + l\cdot w + l\cdot h)][/tex]

[tex]k_{A_{s}} = k^{2}[/tex]

Volume

[tex]w'\cdot h' \cdot l' = k_{V}\cdot (w\cdot h \cdot l)[/tex]

[tex](k\cdot w)\cdot (k \cdot h)\cdot (k \cdot l) = k_{V}\cdot (w\cdot h \cdot l)[/tex]

[tex]k_{V} = k^{3}[/tex]

Where [tex]k = \frac{p'}{p}[/tex].

If we know that [tex]p' = 30\,in[/tex] and [tex]p = 20\,in[/tex], then we proceed to calculate all the ratios:

[tex]k_{p} = \frac{30\,in}{20\,in}[/tex]

[tex]k_{p} = \frac{3}{2}[/tex]

[tex]k_{A_{s}} = \frac{9}{4}[/tex]

[tex]k_{V} = \frac{27}{8}[/tex]

Answer:

ratio of heights: (3/2)

Ratio of surface area: (9/4)

Ratio of volumes: (27/8)

Step-by-step explanation:

got this right, hope it helps :)
