Rectangular prism is also called cuboid.

Formula :

[tex]\bigstar \: \boxed{\sf {Volume_{(Cuboid)} = \ell \times b \times h}} \\ [/tex]

[tex] \longmapsto [/tex] Volume = (3 × 6 × 2) feet[tex]\sf ^3 [/tex]

[tex] \longmapsto [/tex] Volume = (18 × 2) feet[tex]\sf ^3 [/tex]

[tex] \longmapsto [/tex] Volume = 36 feet[tex]\sf ^3 [/tex]

Therefore,

Answer:

[tex]gradient \: of \: y = 3x - 5 \: is \: 3 \\ m = 3 \\ for \: perpendicular \: m {}^{.} \times m = - 1 \\ 3m {}^{.} = - 1 \\ m {}^{.} = - \frac{1}{3} \\ from \: \: y = mx + c \\ at \: (8,5) \: \: 5 = - \frac{1}{3} \times 8 + c \\ c = - \frac{15}{8} \\ hence \: \: y = - \frac{1}{3} x - \frac{15}{8} [/tex]

Answer:

x = 6

y = -1

Step-by-step explanation:

x = - 6y ----------------------(I)

4x + 10y = 14 ------------------(II)

Substitute x = -6y in equation (II)

4*(-6y) + 10y = 14

-24y + 10y = 14  {Combine like terms}

           -14y = 14   {Divide both sides by 1-4}

               y = 14/-14

y = -1

Now, substitute y = -1 in equation  (I)

x = - 6*(-1)

x = 6

there should be a point on the y-axis at positive 5 and for the rest of the points go right 1 up 4 and left 1 down 4

Answer:

0.85

Step-by-step explanation:

The Z-score for Tiffany's exam grade will be 0.85. The value of Z score for the different distribution is different.

The z-score is a numerical assessment of a value's connection to the mean of a set of values, expressed in terms of standards from the mean, that is used in statistics.

The Z score is found as;

[tex]\rm Z= \frac{x-\mu}{\sigma} \\\\ Z=\frac{80-77}{3.5} \\\\ Z=0.85[/tex]

Hence,the Z-score for Tiffany's exam grade will be 0.85.

Answer:

One acute angle is 31 degrees and the other  acute angle is ( 31+28=)  59 degrees.

Step-by-step explanation:

In the right angled triangle one angle is always equal to 90 degrees.

Suppose <a= 90 degrees

     < b= x degrees

    < c= x+28 degrees

The sum of all the angles of the triangle are always equal to 180 degrees

therefore

<a+ <b+<c= 90 + x+ x+28 = 180

or

2x= 180- 28- 90

2x=62

x= 31 degrees

One acute angle is 31 degrees and the other  acute angle is ( 31+28=)  59 degrees.

An acute angle is an angle which has less than 90 degrees in measurement .

Hence both angles of the right angle triangle are acute angles , 31 and 59 degrees.

Answer:

n must be 27

Step-by-step explanation:

Let this number be x.  Then -6(n - 12) = -90.

Dividing both sides by -6 yields n - 12 = 15.

Add 12 to both sides.

Then n must be 27.

Check:  subtract 12 from 27; this yields 15.  Now multiply this result by -6.  The result is -90, which was expected.

Answer:

$9.75

Step-by-step explanation:

Here are two ways of solving this:

Method 1) calculate 35% of original price and subtract from original price

original price: $15

discount rate: 35%

amount of discount: 35% of $15 = 0.35 * $15 = $5.25

final price = original price - amount of discount = $15 - $5.25 = $9.75

Method 2) calculate the percent the discount amount is, and calculate the amount

original price = $15 = 100% of original price

discount rate = 35%

Since the discount rate is 35%, then 100% - 35% = 65%, meaning the sale price is 65% of the original price.

final price = 65% of $15 = 0.65 * $15 = $9.75

Answer: $9.75

Part A: Sally paid less money per pound than Fred did

Part B: John paid $3.58 for 5.5 pounds of apples at the Grocery Mart

Part C: y = 0.65x

Step-by-step explanation:

Part A:

Sally: 1.5/2.5 = x/1

cross multiply: 2.5x = 1.5*1

simplify: 2.5x = 1.5

divide both sides by 2.5: x = 0.6

Fred: 1.95/3 = x/1

cross multiply: 3x = 1.95*1

simplify: 3x = 1.95

divide both sides by 3: x = 0.65

Fred paid 65¢/pound while Sally paid 60¢/pound

Part B:

price/pound*amount John bought: 0.65/1 = x/5.5

cross multiply: 1x = 0.65*5.5

simplify: x = 3.575

Part C:

y = 0.65x

Answer:

Simon is incorrect

Step-by-step explanation:

3^0 is not 0, it is 1.

A way of thinking about this is if to get from 3^2 to 3^1, you need to divide by 3, then to get from 3^1 to 3^0 you need to divide by 3 again. 3 divided by 3 is 1.

This means 3^0*3^2=1*9=9
