Answer:
a = 8,059.52 m²
Step-by-step explanation:
Area of square
a = s²
a = 56²
a = 3,136
--------------------
Area of circle
a = πr²
a = 3.14(56/2)²
a = 2,461.76
Area of 4 semicircles = area of 2 circles
a = 2,461.76 * 2
a = 4,923.52
-----------------------
Total area
a = 3,136 + 4,923.52
a = 8,059.52 m²
. The temperature on Monday was −5∘C . By Tuesday the temperature rose to −2∘C. Find the change in temperature.
Answer: [tex]3^{\circ}C[/tex]
Step-by-step explanation:
Given
The temperature on Monday was [tex]-5^{\circ}C[/tex]
By Tuesday, it becomes [tex]-2^{\circ}C[/tex]
Change in temperature is the difference between the two temperatures.
[tex]\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C[/tex]
Therefore, the change in temperature is [tex]3^{\circ}C[/tex].

A carpenter has two pieces of wood. He wants to find the density of each piece.
The first piece came from a birch tree. The piece of birch wood measures 2 meters by 4 meters by 3 meters and weighs (mass) 16 kilograms.
The second piece came from a cypress tree. The piece of cypress wood measures 3 meters by 5 meters by 2 meters and weighs (mass) 15.3 kilograms.
Which piece of wood has a greater density?
Answer:
The wood from the birch tree has a greater density than the wood that came from the cypress tree.
Step-by-step explanation:
Density formula: mass/volume
2 times 4 times 3=24 meters for the volume
Birch tree: 16/24 is the density
3 times 5 times 2=30 meters for the volume
Cypress tree: 15.3/30 is the density
If we convert the densities of each piece of wood to decimal it will be easier to determine which has a greater density.
So birch tree: 0.6 repeating is the density
Cypress tree: 0.51 is the density
Therefore the wood that came from the birch tree has a greater density than the wood that came from the cypress tree.

The ratio of the number of red balls to yellow balls in a bag is 4:5. There are 270 balls in
the bag. Which statement is TRUE?
Answer:The ratio of the number of red balls to yellow balls in a bag is 4:5 there are 270 balls in the bag
Step-by-step explanation:
As per linear equation, there are 120 red balls and 150 yellow balls in the bag.
What is a linear equation?A linear equation is an equation that has one or multiple variables with the highest power of the variable is 1.
Given, the ratio of the number of red balls to yellow balls in a bag is 4:5. There are 270 balls in the bag.
Let, there are 4x red balls in the bag.
Therefore, there are 5x yellow balls in the bag.
Now, (4x + 5x) = 270
⇒ 9x = 270
⇒ x = 270/9
⇒ x = 30
The number of red balls = 4x = 4 × 30 = 120.
The number of yellow balls = 5x = 5 × 30 = 150.

WILL GIVE BRAINLIEST AND THANKS. determine if these are tangent to the circle
Answer:
19 Five is not tangent to the circle.
20 Eight is tangent to the circle.
Step-by-step explanation:
In order for one of the legs to be a tangent to a circle, the length must be part of a right angle triple.
I don't think the diagram on the left is, but I'll check it.
5^2 + 12^2 =
25 + 144 =
169
square root of 169 is 13
The length of the hypotenuse should be 13 not 14. Fourteen does not make Pythagorean triple. 13 would. So the line 5 units long does not make a tangent to the given circle.
The diagram on the right is a different story. 6 8 and 10 do make a Pythagorean triple, even though the two diagrams are not the same.
The radius and the distance to the external point form a right angle.
The Pythagorean triple is
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
If A and B are mutually exclusive events, then P(A or B) = P(A) + P(B).

Si hay 30% de probabilidad de que neve y llueva en día de hoy. Si la probabilidad de
lluvia es 40% y la probabilidad de nieve es de 15%. ¿Cuál es la probabilidad de que caída
nieve o llueva en el día de hoy?
Answer:
P(A or B) = 25%
Step-by-step explanation:
P(A and B) = 30%
P(A) = 40%
P(B) = 15%
Apply given formula:
P(A or B) = P(A) + P(B) - P(AB)
= 40%+15+-30%

Write an equation in slope intercept form of the line that passes through the points (1,−6) and (5,−6).
slope intercept form = y=mx+b
m= slope
b= y-intercept
the slope is rise over run, so if the points are (1, -6) and (5, -6), the slope is 0
the y intercept is -6
y = 0x-6
or
y = -6

Answer:
a) a = 60° b = 60° c = 120° d = 60°
b) a = 140° b = 20° c = 60° d = 60°
Step-by-step explanation:
a) Sum of the angles of a hexagon = (6 - 2)180 = 720
Since the hexagon is regular, c = 720/6 = 120
a and c are supplementary, so a = 180 - 120 = 60
d = 120/2 = 60
b)
sum of the angles of a nonagon = (9 - 2)180 = 1260
a = 1260/9 = 140
140 + 2b = 180
2b = 40
b = 20
c = 60 and d = 60 (This is really difficult to explain with the vertices being labeled)

Find the volume of the L shaped composite prism, show clearly how you got your answers
9514 1404 393
Answer:
510 cm³
Step-by-step explanation:
The overall height of the front face is 9+2 = 11 cm.
The overall width of the front face is 6+4 = 10 cm.
Out of that 11 cm by 10 cm rectangle, a cutout is made in the upper right corner. The area of that cutout (in the plane of the front face) is 2 cm high by 4 cm wide.
Then the area of the front face is ...
(11 cm)(10 cm) -(2 cm)(4 cm) = 110 cm² -8 cm² = 102 cm²
The volume of the prism can be found using the formula ...
V = Bh
where B is the area of the "base" of the prism, and h is its height. Here, the "base" is the front face, and the height is the dimension marked 5 cm. The volume is ...
V = (102 cm²)(5 cm) = 510 cm³
The volume of the prism is 510 cm³.
