1/2 + 3/8
1/2 + 3/8 = 4+3/8 = 7/8
Answer:
7 / 8
Step-by-step explanation:
In order to add fractions, the denominators must be the same.
1 / 2 + 3 / 8
Find the least common denominator by prime factorization.
2:2
8:2, 2, 2
To determine the least common denominator (LCD), multiply the common factor 2 times the other factors in blue.
LCD = 2 × 2 × 2 = 8
Multiply 1 / 2 times 4 / 4 so that it will have a denominator of 8.
1 / 2 × 4 / 4 + 3 / 8
= 4 / 8 + 3 / 8
= 7 / 8
Hope this helps :)
¿Cuáles son las longitudes de un terreno rectangular, si se sabe que el ancho es dos veces más pequeño que el largo, y que su área es de 16, 200 m2? cuanto mide el ancho cuanto mide el largo
Answer:
El largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m
Step-by-step explanation:
Un rectángulo es un cuadrilátero con dos lados de igual longitud y dos lados de igual ancho que contiene cuatro ángulos rectos. Para encontrar el área de un rectángulo, debes multiplicar su longitud por su ancho. Es decir, el área del rectángulo es igual al largo por el ancho.
En este caso, sabes que el ancho es dos veces más pequeño que el largo. Entonces, siendo el largo x, el ancho tendrá un valor de x÷2.
Siendo el área del terreno rectangular 16,200 m², entonces
x*(x÷2)= 16,200 m²
Resolviendo:
x² ÷2= 16,200 m²
x²= 16,200*2 m²
x²= 32,400 m²
x= √32.400 m²
x= 180 m
Entonces, el largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m (180 m÷ 2)

True or false: Suppose I rotate a shape 90 degrees counterclockwise. It will end up in the same place as if I moved it 90 degrees clockwise.
True or false: Suppose I rotate a shape 180 degrees counterclockwise. It will end up in the same place if I rotate it 180 degrees clockwise.
Answer:
1. True
2. True
Step-by-step explanation:
Counter clockwise is in the opposite direction that the clock hands move, therefore, both Answers are true.

A penguin population increases by 60%, representing an increase of 3840 penguins. How many penguins were there before the increase?
Answer:
2304
Step-by-step explanation:
The equation for this is 3840*0.6 which equals 2304. And to check, we can divide 2304 by 0.6, and that gives us 3840. I hope this helps! :)

Find the value of each variable in the parallelogram?
Answer:
Step-by-step explanation:
In parallelogram opposite angles are equal
6x = 66 {Divide both sides by 6}
x = 66/6
x = 11
20y - 46 = 13y + 10 {Add 46 to both sides}
20y - 46 + 46 = 13y + 10 + 46
20y = 13y + 56 {Subtract 13y from both sides}
20y - 13y = 13y-13y + 56
7y = 56 {Divide both sides by 7}
y = 56/7
y = 8

8(x-1)=-4x+136
Step-by-step explanation:
Given
8(x - 1) = - 4x + 136
8x - 8 = -4x + 136
8x + 4x = 136 + 8
12x = 144
x = 144 / 12
x = 12

Triangles MNQ and MOP are similar. What is the slope of segment MO?
A. 1/3
B. 1/2
C. 2/3
D. 3/2
Answer:
D. 3/2
Step-by-step explanation:
The scale factor is 1/2 from OP / NQ = 1/2. Because of that, MQ is equal to half of MP and QP is equal to half of MP. Therefore, QP = MQ = 2. The slope of MO is rise over run which is 6 / 4 or 3 / 2.

Step-by-step explanation:
You plan to go snowboarding this weekend in Pennsylvania. The resort charges $15.75 per hour in addition to a $25 deposit to rent a snowboard. Write and solve a linear equation to find the total cost to rent the snowboard from 8:30 a.m. to 12:30 p.m.
Answer:
$88 in total
Step-by-step explanation:
x = number of hours
y = total cost to rent the snowboard.
$25 is already guaranteed
25 + 15.75x = y
since it is 4 hours from 8:30 a.m. to 12:30 a.m. you put 4 into x.
25+15.75(4) = y
88 = y
R=19, M
