Desenhe em uma folha dois quadrados de lado 1dm. Trace uma diagonal em cada um e recorte-os
Answers
Answer:
The given question is
Draw two 1 dm squares on a sheet of paper. Draw a diagonal on each one and cut them out.
So, you need to draw square with sides of 1 dm. However, first, you need to transform from dm to cm.
We know that 1 decimenter (dm) equals 10 centimeters (cm).
That means the square sides are 10 centimerers long. So, you need to draw two squares like the first image attached shows.
Then, to draw their diagonals, you need to draw a line segment from one corner to its opposite corner, you should have an inclined line acroos each square. As the second image attached shows.
There you have it. Two squares of 1 dm side with on diagonal each.

The area of a kite ABCD is 900cm2 and one diagonal is 25cm long. Find the length of the other diagonal. Please answer!!!
Answers
Answer:
72 cm
Step-by-step explanation:
The area (A) of a kite is calculated as
A = [tex]\frac{1}{2}[/tex] × d₁ × d₂ ( d₁ and d₂ are the diagonals )
Here A = 900 and d₁ = 25, thus
[tex]\frac{1}{2}[/tex] × 25 × d₂ = 900 ( multiply both sides by 2 )
25d₂ = 1800 ( divide both sides by 25 )
d₂ = 72 cm

5(x + 1) = 4x + 7
5x + 5 = 4x + 7
x + 5 = 7
x = 2
Answer:

Step 1: Simplify both sides of the equation.
5(x+1)=4x+7
(5)(x)+(5)(1)=4x+7(Distribute)
5x+5=4x+7
Step 2: Subtract 4x from both sides.
5x+5−4x=4x+7−4x
x+5=7
Step 3: Subtract 5 from both sides.

What is the surface area of a rectangular prism that has a height of 5 cm, a width of 10 cm, and a depth of 4 cm?
A rectangular prism with length of 10 centimeters, width of 4 centimeters, and height of 5 centimeters.
[Not drawn to scale]
120 square centimeters
180 square centimeters
220 square centimeters
270 square cemtimeters
Answers
Answer:
220 square centimeters Option c.
Step-by-step explanation:
There are 6 faces of a rectangular prism, so to find the surface area of the prism, add the area of each faces.
Surface Area = 2(lw + lh + wh)
where, l = Length, w = Width and h = Height of the rectangular prism.
According to the given dimensions
Length = 10 cm
Width = 4 cm
Height = 5 cm
Therefore, the surface area of the given rectangular prism will be,
S.A. = 2((10)(4) + (10)(5) + (5)(4))
= 2(40 + 50 + 20)
= 2 (110)
= 220 cm²
Surface area of the rectangular prism will be 220 cm².
We have been given that a rectangular prism that has a height of 5 cm, a width of 10 cm, and a depth of 4 cm. We are asked to find the surface area of the prism.
We will use surface area of rectangular prism to solve our given problem.
[tex]A=2(lw+wh+hl)[/tex], where,
l = Length,
w = Width,
h = Height.
[tex]A=2(10\text{ cm}\cdot 4\text{ cm}+4\text{ cm}\cdot 5\text{ cm}+5\text{ cm}\cdot 10\text{ cm})[/tex]
[tex]A=2(40\text{ cm}^2+20\text{ cm}^2+50\text{ cm}^2)[/tex]
[tex]A=2(110\text{ cm}^2)[/tex]
[tex]A=220\text{ cm}^2[/tex]
Therefore, the surface area of the given prism would be [tex]220\text{ cm}^2[/tex] and option C is the correct choice.

Based on the vertical angles theorem, the measure of angle 1 is: 48°.
What are Vertical AnglesVertical angles are always directly opposite each other and are formed when two straight lines crosses each other.
In the diagram given, the angle that is directly opposite angle is 48°, since it is an alternate angle to 48° formed on lines m and n (lines k and l are parallel lines).

Given Function A with points (–5, –2), (–5, 7) and Function B with points (7, –5), (–2, –5) represent linear functions, thus:
Function A has an undefined slope: no slope
Equation for line A would be: x = -5
Function B has a slope value of: 0.
Equation for line B is: y = -5
Recall:
Slope-intercept form is for a vertical line: x = a number on the x-axisSlope-intercept form is for a horizontal line: y = a number on the y-axisThus:
Linear Function A with the points (–5, –2), (–5, 7):
[tex]Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7 -(-2)}{-5 -(-5)} \\\\[/tex]
[tex]m = \frac{9}{0}[/tex] (can't divide. Undefined)
Function A therefore has no slope (undefined).A line with no slope is a vertical line.The equation for function A will therefore be written as: x = -5
-5 is where the vertical line intersects the x-axis.Linear Function B with the points (7, –5), (–2, –5):
[tex]Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-5 -(-5)}{-2 - 7} \\\\[/tex]
[tex]m = \frac{0}{-9} = 0[/tex]
A slope value of 0 means the line of the linear equation is an horizontal line.The equation for function A will be written as: y = -5
-5 is where the horizontal line intersects the y-axis.In summary, given Function A with points (–5, –2), (–5, 7) and Function B with points (7, –5), (–2, –5) represent linear functions, thus:
Function A has an undefined slope: no slope
Equation for line A would be: x = -5
Function B has a slope value of: 0.

The 5th term in a geometric sequence is 160. The 7th term is 40. What are possible values of the 6th term of the sequence?
A) positive/negative 70
B) 70
C) positive/negative 80
D) 80
Answers
The correct answer is:
The possible value for the 6th term is 40. Thus, the answer is B) 70.
To find the common ratio (r) of the geometric sequence, divide the 7th term by the 5th term:
[tex]\[ r = \frac{40}{160} = \frac{1}{4} \][/tex]
Now, we can find the 6th term (T6) using the common ratio and the 5th term:
[tex]\[ T6 = T5 \times r = 160 \times \frac{1}{4} = 40 \][/tex]
So, the 6th term could be 40. Therefore, the answer is:
B) 70

The inverse of the function y=5x-10 is given by the formula f^-1(x) = (x + 10)/5. This is found by switching x and f(x) in the original equation, then solving for the new function.
Explanation:The problem asked us to find the inverse of the function y=5x-10. Finding the inverse of a function involves reversing the variables and then solving for the new y variable. Here are the steps for this:
Replace y with f(x), giving us the function f(x) = 5x - 10.Switch x and f(x) to find the inverse. This gives us x = 5f-1(x) - 10.Solve for f-1(x). By adding 10 to both sides and then dividing by 5, we find that the inverse function is f-1(x) = (x + 10)/5.Learn more about Inverse Functions here:https://brainly.com/question/35491336

Answers
Answer:
The average force applied to the ball is 84N
Step-by-step explanation:
This problem bothers on the impulse of a force
Given data
Mass of ball m= 0.28kg
Initial speed u= 0m/s
Final speed v= 6m/s
Time of impact t= 0.02s
We know that the impulse of a force
Ft= mv-mu
Hence the force is
F= (mv-mu)/t
F=m(v-u)/t
F= 0.28(6-0)0.02
F= 1.68/0.02
F= 84N

the pressure remains constant, what is the volume of the gas if
its temperature decreases to 72.0°C?
Answers
Answer:
84.6
Step-by-step explanation:
135c + 273.15 = 408 K
72C + 273.15 = 345 K
100 L over 408 K = V2 over 345 K
V2= 84.6
The volume of the gas when temperature decreases to 72.0 °C is 84.6 L
What is volume?Volume is a physical quantity that measures the amount of three-dimensional space occupied by matter (solid, liquid, or gas).
Volume is defined as the three-dimensional space occupied by matter or enclosed by a surface. The SI unit of volume is the cubic meter (m³),
Given that, a sample of gas has a volume of 100.0 L at 135 °C, the pressure remains constant, we need to find that what is the volume of the gas when temperature decreases to 72.0 °C
Converting the temperature into Kelvins =,
135C + 273.15 = 408 K
72C + 273.15 = 345 K
100 L / 408 K = V2 / 345 K
V2 = 84.6
Hence, the volume of the gas when temperature decreases to 72.0 °C is 84.6 L
