Answer:

4000 [tex]m^{3}[/tex]

Step-by-step explanation:

V = 1/3(Bh)  where B is the area of the base and h is the height of the pyramid

B = 20(20) = 400      h = 30

V = 1/3(400)(30) = 4000 [tex]m^{3}[/tex]

Answer:

74 in²

Step-by-step explanation:

Area painted by Micah = 96 ft²

Area painted by Noah = 13750 in²

Converting both area to the same unit :

1 ft² = 144 in²

Therefore, Area painted by Micah :

96 * 144 = 13824 in²

13824 in² > 13750 in² ; hence, Micah painted more ;

To obtain how much more area Micah painted than Noah :

Area painted by Micah - Area painted by Noah

13824 in² - 13750 in²

= 74 in²

Answer:

umm maybe 6/25

Step-by-step explanation:

Set of events " rolling a six-sided cube and drawing 6 marbles out of a bag " have an equally like chance of occurring.

Option B is correct.

Probability of series of experiments shown below;

A. When spinning a spinner with 3 sections then probability of one section is [tex]\frac{1}{3}[/tex] .

 When tossing a coin, then probability of getting head or tail is [tex]\frac{1}{2}[/tex]

So that, set A has not equally like chance of occurring.

B. When rolling six-sided cube, probability of getting one number is [tex]\frac{1}{6}[/tex]

   When one marble is drawn out of 6 marble in a bag, then  probability is [tex]\frac{1}{6}[/tex]

Therefore, set B has equally like chance of occurring.

Mary earns $11.5 per hour.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

Mary earns $247.25 for gardening.

Mary worked for 21.5 hours.

So, Mary earns per hour

Answer:

13.5 is the next term

4, 6, 9, 13.5

Step-by-step explanation:

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 3/2

formula= an=a1⋅r^n-1

Answer:

45.5625

Step-by-step explanation:

The pattern seems to be x + (x/2) = y where x is the previous number and y is the next number.

4 + (4/2) = 6

6 + (6/2) = 9

therefore we continue the pattern. In doing so we get:

30.375 + (30.375/2) = 45.5625

Step-by-step explanation:

it’s like pemdas you have to do that first then you go on to added the 3+ whatever 12/3 is

Answer:

He didn't follow the pemdas rule (see explanation)

Step-by-step explanation:

Rayan's mistake is that he didn't follow the pemdas rule, which states that you start with wat is inside parentheses first, then exponents then multiplication and division(from left to right) and then adding and  subtracting (from left to right).

Present temperature is [tex]67^{\circ}F[/tex]

The difference in temperature i.e.  

[tex]\Rightarrow \text{Previous Temperature}-\text{Present temperature}=8\\\Rightarrow \text{Previous Temperature}=8+67=75^{\circ}F[/tex]

Answer:

0.5

Step-by-step explanation:

We can calculate the probability of picking a red marble by:

- adding all the marbles together

- then subtract the amount of red marbles by the number found previously.

2 + 3 + 5 = 10

10 - 5 = 5

5 is what of 10?

5 is 50% of 10.

50% means 0.5 out of 1.

Your answer is 0.5.

Hope this helps. Have a nice day.

Answer:

y=21/5, x=7/10

Step-by-step explanation:

Substitute y=6x

4x=6x=7

Simplify 4x+6x

10x=7

isolate x for 10x=7:

10x=7

Divide both sides by 10:

10x/10=7/10

Simplify:

x=7/10

For y=6x substitute x=7/10

y=6*7/10

Convert element to fraction:

6/1*7/10

Cross- cancel common factor:2

3/1*7/5

Multiply fractions:

3*7/1*5

Multiply the numbers:3*7=21

=21/5

y=21/5

The solutions to the systems of equations are:

y=21/5,x=7/10

Answer:

x = 26

Step-by-step explanation:

There are two numbers and average is the sum of a certain amount of numbers divided by the same amount.

21 × 2 = 42

42 - 16 = 26

x = 26

Answer:

x = 26

Step-by-step explanation:

Forming the equation,

→ (16 + x)/2 = 21

Now the value of x will be,

→ (16 + x)/2 = 21

→ 16 + x = 21 × 2

→ 16 + x = 42

→ x = 42 - 16

→ [ x = 26 ]

Hence, the value of x is 26.

Answer: Hi i hope your doing good well the answer is 55

Step-by-step explanation: Angles one and two are complementary. So we know the sum of their measures is 90 degrees. So, to find the measure of angle two, subtract the measure of angle one from 90 degrees. We substitute in the given value of the measure of angle one, which is 35 degrees. Subtracting, we find that the measure of angle two equals 55 degrees.
