Estimate the perimeter of the figure to the nearest tenth.
(I NEED HELP PLZZZZ)
Determina el perimetro de las figuras geometricas que forman la rayuela
Perimetro: L=50 cm
Expresión:
Sustitucion:
P=_______/
La figura es un cuadrado y cada lado mide 50 cm
Answer:
2000cm
Step-by-step explanation:
Rayuela es un juego jugado por niños que se compone de 10 cuadrados.
Se nos da a partir de la pregunta anterior, la longitud del lado de un cuadrado = 50 cm
La fórmula para el perímetro de un cuadrado es 4a
Donde a = longitud del lado
El perímetro de 1 cuadrado =
4 × 50 cm
= 200cm
El perímetro de los cuadrados totales en la rayuela.
1 cuadrado = 200 cm
10 cuadrados = x
Multiplicar cruzada
x = 10 × 200 cm
x = 2000 cm
Por lo tanto, el perímetro de las figuras geométricas de una rayuela = 2000cm.

Rectangle ABCD has coordinates A(-10,5) B(10,5) C(10,0) and D(-10,0). Rectangle A’B’C’D’ has coordinates A’(-10,-5) B’(10,-5) C’(10,0) and D’(-10,0). Rectangle A’’B’’C’’D’’ has coordinates A”(-2,-1) B”(2,-1) C”(2,0) and D”(-2,0), which transformations describe why rectangles ABCD and A”B”C”D” are similar?
A)) rectangle ABCD was reflected across the X axis and then dilated by a scale factor of 1/5 to form rectangle A”B”C”D
B)) rectangle ABCD was dilated by a scale factor of 5 and then rotated 90 degrees counterclockwise to form rectangle A”B”C”D”
C)) rectangle ABCD was dilated by a scale factor of 1/5 then rotated 90 degrees counterclockwise to form rectangle A”B”C”D”
D)) rectangle ABCD was reflected across the Y-axis and then dilated by a scale factor of 5 to form rectangle A”B”C”D”

Answer:
448.25(2dp)
Step-by-step explanation:
1. Find the are of the entire rectangle:
length x breadth = 38 x 28 = 1064mm^2
2. Find the area of one semicircle
([tex]\pi[/tex]r^2) divided by 2 =( [tex]\pi[/tex] x 14^2)divided by 2 = 98 [tex]\pi[/tex] = 307.8760801... = 307.88 mm^2
3. Multiply the area by 2
307.88 x 2 = 615.75 mm^2. [ The sum of areas of 2 semicicles]
4. Subtract the area of the 2 semicircles from the area rectangle
1064-615.75 = 448.25 (2dp)

How to find coordinates of a point using ratio
m1=3, m2= 1
point A= (-5,4)
point B=(7,-2)
x=m1x2+m2x1/ m1+m2 , y=m1y2+m2y1 / m1+m2
x= 3×7 +1×-5/3+1 , y= 3×-2+1×4 / 3+1
x= 21-5/4, y= -6+4/4
x= 16/4, y= -2/4
x= 4, y= 0.5

Suppose you invest money in two accounts. One of the accounts pays 4% interest annually, and
the other account pays 5% interest annually. You have $ 2000 more invested in the account paying
4% than in the account paying 5%. How much do you have invested in the account paying 4% if
you earn $ 670 interest in a year?
Answer:
$16,750
Step-by-step explanation:
It took a lot of plugging in and guessing
The formula used was 16750(1+.04)^1
That equaled 17420
17420-16750 is 670
Hope this helps
