Tanya paints the walls of her family room.
The room measures 3 m by 4 m by 7 m.
The walls need 2 coats of paint. A 4-L can of paint covers 40 m².
a) How much paint should Tanya buy?
Answer:
6.1
Step-by-step explanation:
Surface area of the room = 2(lw + hl + hw)
Where,
l = length = 7 m
w = width = 4 m
h = height = 3 m
Surface area of the room = 2(lw + hl + hw)
= 2(7*4 + 3*7 + 3*4)
= 2(28 + 21 + 12)
= 2(61)
= 122 m²
A 4-L can of paint covers 40 m²
Number of 4-L can of paint needed for 1 coat = 122 m² / 40 m²
= 3.05 4-L can of paint
The walls need 2 coats of paint
Number of 4-L can of paint needed for 2 coats = Number of 4-L can of paint needed for 1 coat × 2
= 3.05 × 2
= 6.1 4-L can of paint

Answer:
D. [tex] \frac{3}{20}[/tex]
Step-by-step explanation:
[tex]l = \frac{ \theta}{360 \degree} \times c \\ \\ l = \frac{54 \degree}{360 \degree} \times c \\ \\ l = \frac{3}{20} \times c \\ \\ [/tex]
Thus, the length of the arc RST is [tex] \frac{3}{20}[/tex] times of the circumference of the circle with center C.
0.51 (1 repeating) as a fraction simplest form
A fraction simplest form of the given number 0.51 (with 1 as repeating ) is equal to 4.6/9.
A number whose decimal representation ultimately becomes periodic (i.e., the same sequence of digits repeats without end) is known as a repeating decimal, sometimes known as a recurring decimal.
The given number is:
0.51111111....
To express 0.51111111111... as a fraction in simplest form,
Follow these steps:
Assume x = 0.51111111111...
To eliminate the repeating decimal,
Multiply both sides of the equation by 10,
Which will shift the decimal point one place to the right.
Therefore, 10x = 5.111111111...
Subtract the original equation (x) from the modified equation (10x).
This will eliminate the repeating part, leaving us with a whole number.
So, subtracting the two equations gives us:
10x - x = 5.111111111... - 0.51111111111...
9x = 4.6
Divide both sides of the equation by 9. So,
x = 4.6/9
Hence,
The required fraction is 4.6/9.

3. Sue's average for 9 games of bowling is 108. What is the lowest score she can receive for the
tenth game to have an average of 110?
Answer: 128
Step-by-step explanation:
Sue's average for 9 games of bowling is 108. Therefore, the total scores for the 9 games is:
= 108 × 9
= 972
To have an average of 110 in 10 games, her total score will be:
= 110 × 10
= 1100
Therefore, the lowest score that she can get will be the difference between the values calculated above and this will be:
= 1100 - 972
= 128

Answer:
[tex][AB]^2[/tex]
Step-by-step explanation:
Given
Matrices A and B
Required
Represents the square of A and B
The interpretation of the question is that:
The square of the product of A and B
This can be represented as:
The square(product of A and B)
Product means *
So, we have:
The square(A * B)
The square means ^2
So, we have:
[tex][A * B]^2[/tex]
This gives:
[tex][AB]^2[/tex]
Hence, the second option is correct

Los ingresos de Mary en 2019 fueron un 20 por ciento mayores que sus ingresos en 2018. ¿Cuál es la relación entre los ingresos de Mary en 2019 con respecto a sus ingresos en 2018?
a) 1 a 5
b) 5 a 6
c) 6 a 5
d) 5 a 1
e) 20 a 1
Answer:
La respuesta correcta es la opción d) 5 a 1.
Step-by-step explanation:
Para calcular la relación entre los ingresos de Mary en 2019 ([tex]I_{2019}[/tex]) con respecto a sus ingresos en 2018 ([tex]I_{2018}[/tex]), partimos de que los ingresos de Mary en 2019 fueron un 20% mayores que sus ingresos en 2018:
[tex]I_{2019} = 20\% \: I_{2018}[/tex]
[tex] I_{2019} = \frac{20}{100}I_{2018} [/tex]
[tex] \frac{100}{20}I_{2019} = I_{2018} [/tex]
[tex] 5I_{2019} = I_{2018} [/tex]
Entonces, la relación entre los ingresos de Mary en 2019 es 5 veces los ingresos de Mary en 2018. Por lo tanto, la respuesta correcta es la opción d) 5 a 1.

using this, we can see that x = 73 and y = 13
using this, tan(x-y) = tan(73-13) = tan(60)
therefore, A = 60
we know that tan(60) = √3
therefore, B = 3

What are the coordinates of Rx=3(G)?
Answer:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).
