the prism below is made of cubes which measure 1/3 of a centimeter on one side. What is the volume?

A. 6 cubic cm
B.2/3 cubic cm
C.18 cubic cm
D.8/3 cubic cm

Using proportions, it is found that the conversions are given as follows:

a) 175.89 rands were worth $14.07.

b) 56.56 dollars were worth 708.13 rands.

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

In this problem, we have the following proportion:

1 rand - 0.08 U.S. dollars.

Item a:

175.89 x 0.08 = $14.07, hence:

175.89 rands were worth $14.07.

Item b:

56.65/0.08 = 708.13, hence:

56.56 dollars were worth 708.13 rands.

Answer:

= 6 items per hour

Explanation:

This is a fraction equal to 18 items ÷ 3 hours

We want a unit rate where 1 is in the denominator, so we divide top and bottom by 3

18 items ÷ 3

3 hours ÷ 3

= 6 items/1 hour

= 6 items/hour

= 6 items per hour

Answer:

3

Step-by-step explanation:

to find the volume of a rectangular prism, Volume = length x height x width

Volume is 45 units (given)

length is 5 units (given)

45 = 5 x w x l

45 / 5 = w x l

9 = w x l

only 3 x 3 = 9 works with these numbers

45 = 5 x 3 x 3

The total surface area of the cone is 542.592 square mm

The formula for calculating the total surface area of a cone is expressed as:

TSA = πr(r + l)

where

r is the radius of the cone

l is the slant of the cone

Given the following parameter

l = 13.6mm

r = 8mm

Substitute

TSA = π(8)(8+13.6)
TSA = 3.14(8)(21.6)

TSA = 542.592 square mm

Hence the total surface area of the cone is 542.592 square mm

Answer:

n = -10

Explanation:

[tex]\Rightarrow \sf \dfrac{1}{n} +\dfrac{4n+16}{n^2-6n} =\dfrac{4}{n-6}[/tex]

Factor the common term

[tex]\Rightarrow \sf \dfrac{1}{n} +\dfrac{4n+16}{n(n-6)} =\dfrac{4}{n-6}[/tex]

Make the denominator same

[tex]\Rightarrow \sf \dfrac{n-6}{n(n-6)} +\dfrac{4n+16}{n(n-6)} =\dfrac{4}{n-6}[/tex]

Join the fractions

[tex]\Rightarrow \sf \dfrac{n-6+4n+16}{n(n-6)}=\dfrac{4}{n-6}[/tex]

simplify the following

[tex]\Rightarrow \sf \dfrac{5n+10}{n(n-6)}=\dfrac{4}{n-6}[/tex]

cross multiply

[tex]\Rightarrow \sf\left(5n+10\right)\left(n-6\right)=n\left(n-6\right)\cdot \:4[/tex]

cancel out common term

[tex]\Rightarrow \sf\left(5n+10\right)=4n[/tex]

exchange sides

[tex]\Rightarrow \sf 5n-4n=-10[/tex]

Yes, there is statistical evidence that the drug is effective in reducing infarct size because p-value is less than the significance value.

Let us first define the hypotheses;

Null Hypothesis; H₀: µ = 25

Alternative Hypothesis; H₁: µ < 25

Standard Deviation; σ = 10

Sample mean; x' = 16

Sample size; n = 8

z-score is;

z = (16 - 25)/(10/√8)

z = -2.55

From online z-score table, the p-value is 0.005

Since p-value is less than the significance value, then we reject the null hypothesis and conclude that the drug is effective in reducing infarct size.

Answer:12, 84 and 84

Step-by-step explanation:

since we  know 3 angles of a triangle = 180 degrees

1 angle = 12 degrees

12 + x + x = 180

12 + 2x = 180

2x= 180 - 12

2x = 168

x = 168/2

x = 84 degrees

Answer:

64° , 64° , 52°

Step-by-step explanation:

       The two angles that are same be 'x'

        Third angle = x  - 12

Sum of all angles of triangle = 180

                      x + x + x -12      = 180

                                   3x - 12 = 180

                                          3x = 180 + 12

                                          3x = 192

                                             x = 192/3

                                             x = 64

x - 12 = 64 - 12

         = 52

Find density:

· mass/volume

· 16/64

· 0.25 g/cm³

Answer:

810 cm^3

Step-by-step explanation:

Since,the l(length) b(breadth) & h(height) of the cuboid bear the ratio 5 : 3 : 2 ,we could assume it as:

We know that,

So substitute the dimensions we assumed:

[tex] \rm \: Total \; Surface\; area \: of \: the \; cuboid = 2(5z \times 3z + 3z \times 2z + 2z \times 5z[/tex]

[tex] \implies \rm \: 279 = 31 {z}^{2} [/tex]

[tex] \rm \implies {z}^{2} = \cfrac{279}{31} [/tex]

[tex] \rm \implies {z}^{2} = 9[/tex]

[tex] \implies \rm \: z = \sqrt{9} [/tex]

[tex] \rm \implies \: z = \sqrt{3 \times 3} = 3[/tex]

Hence, according to the formula,

We got the dimensions of the cuboid, i.e.

Then, solve.

Hence,the volume of the cuboid will be 810 cm^3

(f + g)(x) = 2 x²+6x+2

The composition of a function is an operation where two functions say f and g generate a new function say h in such a way that h(x) = g(f(x)). It means here function g is applied to the function of x. So, basically, a function is applied to the result of another function.

Given function is:

f ( x ) = 2 x + 2 and g ( x ) = 2 x² + 4 x

So,

(f + g)(x)

= f(x)+g(x)

= 2x+2+2 x² + 4 x

=2 x²+6x+2

Hence, (f + g)(x) = 2 x²+6x+2.
