Answer:

Thursday.

Step-by-step explanation:

We have that the first day of Alex's trip was a Monday, that is to say that the next Monday will be obtained by adding 7 to the previous numbers.

1 + 7 = 8

8 + 7 = 15

15 + 7 = 22

22 + 7 = 29

29 + 7 = 36

We have that the 36th is a Monday, therefore:

37, Tuesday

38, Wednesday

39, Thursday

In other words, the 39th would be Thursday.

Answer:

4000

Step-by-step explanation:

this can be found by using the equation

1600/x = 40/100

cross multiply

40x = 160000

simplify

x= 4000

To find the total number of visitors the art museum had in the month, divide 1,600 by 0.4.

To find the total number of visitors the art museum had in the month, we can use the given information. We know that 1,600 visitors represents 40% of the total number of visitors for the month. To find the total number of visitors, we can set up the following equation:

1,600 = 0.4 * total number of visitors

To solve for the total number of visitors, we divide both sides of the equation by 0.4:

total number of visitors = 1,600 / 0.4 = 4,000

Therefore, the art museum had a total of 4,000 visitors that month.

The value of [tex]\(10^2 - 4^3\)[/tex] is [tex]\(6^2\)[/tex], equivalent to 36.

To solve this expression, first, let's calculate each part:

[tex]$10^2 = 10 \times 10 = 100$[/tex]

[tex]$4^3 = 4 \times 4 \times 4 = 64$[/tex]

Now, we can substitute these values into the expression:

[tex]$10^2 - 4^3 = 100 - 64 = 36$[/tex]

Now, we need to express 36 as a power of 6. We can see that [tex]$36 = 6^2$[/tex], so:

[tex]$36 = 6^2$[/tex]

Therefore, the value of [tex]$10^2 - 4^3$[/tex] as a power of 6 is [tex]$6^2$[/tex]

Answer and Step-by-step explanation:

You are correct in that we need to use the Law of Sines: [tex]\frac{c}{sinC} =\frac{b}{sinB}=\frac{a}{sinA}[/tex].

Here, when we use the Law of Sines, we have: [tex]\frac{28}{sin(63)}=\frac{29}{sinB}[/tex].

Cross multiply:

(sinB) * 28 = (sin63) * 29

28sinB ≈ 25.839

sinB ≈ 0.9228

Now, in order to solve for B, we need to use inverse sin ([tex]sin^{-1}[/tex]):

[tex]sin^{-1}(sinB)=sin^{-1}(0.9228)[/tex]

The sines on the left cancel out, and we're left with:

B ≈ 67.3 degrees

Now, one thing to keep in mind when doing Law of Sines is that there is potentially more than one answer possible for the degree measure. The other degree measure can be found by subtracting this one from 180:

180 - 67.3 = 112.7 degrees.

Hope this helps!

Answer:

67.3° , 112.7°

Step-by-step explanation:

sinx = 0.9228

Take inverse of sin, you get:

x = 67.3389176683

Since sin is positive in first two quadrants, second angle is:

180 - 67.3389176683

= 112.6610823317

Answer: 18pi unit squared

Step-by-step explanation:

Area of a circle = πr2

Radius of Circle G= 3units

Area of circle G= πr2

= π (3×3)

= 9π unit squared

Maria draws a circle with double the area of circle G. This will be:

2 × 9π

= 18π2

= 18pi unit squared

Answer:

18*pi units squared.

Step-by-step explanation:

The area of a circle can be calculated with the following formula:

Area = pi * r^2

Where r is the radius.

The circle G have a radius of 3 units, so its area is:

Area1 = pi * r^2 = pi * 3^2 = 9*pi

If the circle that Maria draws has double the area, so her circle have a area of:

Area2 = 2 * Area1 = 2*9*pi = 18*pi units squared.

Answer:

24 cracks will be filled

Step-by-step explanation:

Here, the first question asks how to convert 3 pounds to ounces.

we can do this using a mathematical approach. To convert pounds to ounces, we need to know that there are 16 ounces in a pound. so to convert pounds to ounces, we just need to multiply the number of pounds we have by 16 to get the equivalent number of ounces.

The second question asks to give the number of cracks that be repaired.

From the question, we were made to know that each of the cracks would eat up 2 pounds of cement to be filled.

Let’s calculate the amount of cement we have. That would be 3 * 16 = 48 ounces of cement.

The amount of cracks to be filled is thus 48 ounces/2 ounces = 24 cracks

Two or more expressions with an Equal sign is called as Equation.

Given,

Sam and her 3 friends each bought a ticket at the movie theater,

They bought a large tub of popcorn to share for $8.

Total cost was $36.

We have to find the cost of each ticket.

Let us remove 8 from the cost 36.

Thirty six minus eight equal to twenty eight.

36-8 = 28

Let us divide twenty eight by three because there are three friends

28/3=9.30

Hence if Sam and her 3 friends each bought a ticket at the movie theater, and they also bought a large tub of popcorn to share for $8. If the total cost was $36 then $9.3 is the cost of each ticket.

Answer: They won 22 gold, 18 silver and 12 bronze.

Step-by-step explanation: Suppose gold is g, silver is s and bronze is b.

The number of silver was 6 less than twice of bronze: s = 2b - 6

Gold was 4 more than silver: g = s + 4

Total is 52: g + s + b = 52

We have 3 equations and 3 variables. To determine each one:

s = 2b - 6 (1)

g = s + 4 (2)

g + s + b =52 (3)

Substitute (1) in (2):

g = 4 + 2b - 6

g = 2b - 2 (4)

Using (1) and (4), substitute in (3)

2b - 2 +2b - 6 + b = 52

5b = 52+8

b= [tex]\frac{60}{5}[/tex]

b = 12

With b, we find s:

s = 2.12 - 6

s = 18

With s, we find g:

g = 4 + 18

g = 22

Therefore, the team won 22 gold, 18 silver and 12 bronze.

Answer:

Gold : 22 medals , Silver : 18 medals, Bronze : 12 medals

Step-by-step explanation:

Solution:-

- Denote the total number of medals won by USA, T = 52

- The number of bronze medals = x

- The number of silver medals = y

- The number of gold medals = z

- We are given that number of silver medals (y) was 6 ​fewer (less)​ than twice the number of bronze medals (x). So the mathematical representation of this observation would be:

                                  y = 2x - 6  

- Similarly, the number of gold medals (z) was ​four more than​ the number of silver medals (y).  So the mathematical representation of this observation would be:

                                 z = y + 4

- The total number of medals T:

                                T = x + y + z

- We have 3 equations and 3 unknowns. Solve the equations simultaneously,

                                z = 2x - 6 + 4 = 2x - 2

                                T = x + ( 2x - 6 ) + ( 2x - 2)

                                52 = 5x - 8

                                5x = 60

                                x = 12 bronze medals

                                z = 2x - 2

                                z = 2*12 - 2

                                z = 22 gold medals

                                z = y + 4

                               y = 22 - 4

                               y = 18 silver medals

To calculate a decimal multiplier to decrease a quantity by a certain percentage, subtract the percentage you want to decrease by from 100% and then convert to a decimal. For a 3.4% decrease, the decimal multiplier is 0.966.

The decimal multiplier to decrease a quantity by 3.4% can be calculated by subtracting the percentage decrease from 100%, then converting into decimal form. Therefore, 100% - 3.4% gives us a remainder of 96.6%. This is the amount we want to remain after the decrease. Convert this to a decimal multiplier by dividing by 100, i.e., 96.6% ÷ 100 = 0.966. Thus, the decimal multiplier to decrease by 3.4% is 0.966.

Answer:

The weigth of the three heavy balls is 35.1 pounds.

Step-by-step explanation:

In order to solve this problem we will call the weigth of the light ball by "l" and the weigth of the heavy ball by "h". The total weigth of the six balls is 52.65 pounds, so we have:

3*l + 3*h = 52.65

We know that the weigth of the heavy ball is twice the weight of the light ball, so we have:

h = 2*l

We can use this value on the equation to solve for "l". We have:

3*l + 3*(2*l) = 52.65

3*l + 6*l = 52.65

9*l = 52.65

l = 52.65/9 = 5.85 pounds

h = 2*l = 2*5.85 = 11.7 pounds

3*h = 35.1 pounds

The weigth of the three heavy balls is 35.1 pounds.

Final answer:

The weight of a light bowling ball is approximately 5.85 pounds. The weight of a heavy bowling ball is approximately 11.7 pounds.

Explanation:

The total weight of the 6 bowling balls is 52.65 pounds. Let's represent the weight of a light bowling ball as x pounds. Since the weight of a heavy bowling ball is twice that of a light bowling ball, the weight of a heavy bowling ball is 2x pounds. So we can set up the equation:

3x + 3(2x) = 52.65

Simplify and solve for x:

3x + 6x = 52.65

9x = 52.65

x = 52.65/9

x = 5.85

The weight of a light bowling ball is approximately 5.85 pounds. The weight of a heavy bowling ball is twice that, which is approximately 11.7 pounds.
