Answers
Answer:
1) c) 96 cm
2) c) 17,15 m
3) c) 294 m
4) d) 332 metros
Step-by-step explanation:
1)
La fórmula para el perímetro de un rectángulo = 2L + 2W
= 2 (largo + ancho)
L = longitud
W = ancho
Se nos dice en la pregunta que:
La longitud de un rectángulo es tres veces su ancho. Si el ancho es de 12 cm
Por lo tanto,
L = 3 W
L = 3 × 12
Largo = 36cm
Por lo tanto, el perímetro =
2 (largo + ancho) cm
= 2 (36 + 12) cm
= 2 (48) cm
= 96 cm
2)
La fórmula para el perímetro de un heptágono regular = 7a
Donde a = longitud de un lado
De la pregunta,
a = 2,45 m laterales
Por lo tanto, el perímetro de un Heptágono regular = 7 (2,45 m)
= 17,15 m
3)
La fórmula para el perímetro de un rectángulo = 2L + 2W
= 2 (largo + ancho)
L = longitud
W = ancho
Se nos dice en la pregunta que:
Si un campo de fútbol tiene 98 m de largo y su ancho es igual a la mitad de esta medida,
Por lo tanto,
L = 98 m
W = 1/2 de longitud
Ancho = 1/2 (98)
= 49
Por lo tanto, el perímetro =
2 (largo + ancho) m
= 2 (98 + 49) m
= 2 (147) m
= 294 m
4)
El parque es de forma rectangular.
Longitud = 45 m
Ancho = 38.000 mm
Convertir mm en m
1 milímetro = 0,001 metro
38.000 milímetro =
38.000 × 0,001 metros
= 38 metros (38 m)
La distancia alrededor del parque = perímetro del parque
Perímetro = 2 (L + W)
= 2 (45 + 38)
= 2 (83)
= 166 m
Distancia alrededor del parque una vez = 166 m
Pero nos dijeron que dio la vuelta al parque 2 veces, por lo tanto, la distancia que recorrió = 166 m × 2
= 332m

If 2x-y=9 and 3x+4y=19, then y=
Answers
Answer:
x = 5
y = 1
Step-by-step explanation:
2x - y = 9
3x + 4y = 19
We multiply the first equation by 4
8x - 4y = 36
3x + 4y = 19
11x = 55
x = 5
Now we put 5 in for x and solve for y
2(5) - y = 9
10 - y = 9
-y = -1
y = 1
Let's Check the answer
2(5) - 1 = 9
10 - 1 = 9
9 = 9
So, x = 5 and y = 1 is the correct answer.

According to the solving If the room's width is 6 meter's, then its length must be 10 meter's.
What is length?Distance is measured by length. The quantity of length has the dimension of distance there in International System of Quantities. Most measurement systems choose a base unit for length from which all subsequent units are derived. The metre serves as the fundamental unit of length in the International System of Units.
How do you determine length?If you have an area A and a width w, you can calculate the length w by using the formula h = A/w. Its length can indeed be calculated using the formula h = P/2w if you know its perimeter (P) and width (W). If you have the width w and the diagonal
According to the give information:
Let length be x By Given Condition

A textbook store sold a combined total of 248 math and physics textbooks In a week. The number of math textbooks sold was three times the number of physics textbooks sold. How many textbooks of each type were sold?
Number of math textbooks sold:
0
Number of physics textbooks sold:
0
Answers
Answer:
There were 186 math textbooks sold and 62 physics textbooks sold.
Given:
- 248 books sold in total
- math textbooks and physics textbooks sold
- math is three times physics
Step-by-step explanation:
[] First, we can set up mathematical equations for this scenario;
- Let m be math textbooks and p be physics textbooks
m = 3p
248 = p + (3p)
248 = 4p
62 = p
[] Now we can solve for the amount of each books sold;
p = 62 books
3 * p = m
3 * 62 = m
m = 186
[] Lastly, we can check to make sure this will work;
186 + 62 = 248 ✓

What is sine rule?The sine rule states that if a, b and c are the lengths of the sides of a triangle, and A, B and C are the angles in the triangle; with A opposite a, etc., then a/sinA=b/sinB=c/sinC.
The angle at A = 90- 35
= 55°
The angle at B = 90-49
= 41°
Angle at the fire = 180-(41+55)
= 180-96 = 84°
Using sine rule
sin84/13 = sin55/x
xsin84 = 13sin55
0.995x = 10.65
x = 10.65/0.995
x = 10.7 miles

What is the sample size? Give only the number:
The margin of error for this data set is 2.5%. What is the 95% confidence interval for those who say they felt fully engaged with their mortgage provider (rounded to 1 decimal place)?
Answers
The sample size for the Gallup poll is 1,627 adults. The 95% confidence interval for those who say they felt fully engaged with their mortgage provider is approximately 22.0% (rounded to 1 decimal place).
To calculate the 95% confidence interval, we need to consider the margin of error. The margin of error is given as 2.5%, which means that we need to account for plus or minus 2.5% around the observed proportion of 22%.
First, let's calculate the margin of error:
Margin of Error = 2.5% of 22% = 0.025 * 22% = 0.0055
Next, we can calculate the lower and upper bounds of the confidence interval:
Lower Bound = 22% - Margin of Error = 22% - 0.0055 = 21.995% ≈ 22.0%
Upper Bound = 22% + Margin of Error = 22% + 0.0055 = 22.005% ≈ 22.0%
Therefore, the 95% confidence interval for those who say they felt fully engaged with their mortgage provider is approximately 22.0% (rounded to 1 decimal place).
