Angel está adaptando un espacio para hacer actividades recreativas en casa y quiere rodear el borde con plantas, cuántos metros mide el borde si la ecuacion para calcularlo es 2a+2b, donde a representa el ancho y b el largo del espacio, a=1 metro y b=2 metros
Answers
Answer:
El borde mide 6 metros.
Step-by-step explanation:
Sabemos que la ecuación para el borde está dada por:
borde = 2*a + 2*b
Si sabemos que:
a = 1 metro
y
b = 2 metros
podemos simplemente remplazar esos valores en la ecuación para el borde, asi obtendremos:
(es decir, donde hay una "a" en la ecuación, escribimos "1 metro", y end donde hay una "b" en la ecuación, escribimos "2 metros", luego resolvemos)
borde = 2*(1 metro) + 2*(2 metros) = 2 metros + 4 metros = 6 metros.
Podemos concluir que el borde mide 6 metros.

Cost of merchandise= $750
Discount= 15%
Let us find the amount of the discount

if the ratio of type O to non-type O donors at a blood drive was 37:43. how many would be type O out of 300 donors? will try and mark brainliest . please show the work as well
Answers
Answer:
Step-by-step explanation:
Proportion of type O donors = 37/(37+43) = 37/80
300 × 37/80 = 138.75
139 donors out of 300 are type O.
A ratio shows us the number of times a number contains another number. The number of type O donors out of 300 is 139.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that the ratio of type O to non-type O donors at a blood drive was 37:43. Therefore, the number of type O blood donors be represented by 37x and the number of non-type O blood donors be represented by 43x.
Now, the sum of type and non-type O donor is 300. Therefore, we can write,
37x + 43x = 300
80x = 300
x = 3.75
Further, the Number of type O donors out of 300 can be written as,
Number of type O donors out of 300 = 37x = 37(3.75) = 138.75 ≈ 139
Hence, the number of type O donors out of 300 is 139.

If 3000 is placed in an account at 5% interest and is compounded quarterly for 5 years.How much is in the account at the end of 5 years?
Answers
Answer:
FV= $3,846.11
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $3,000
Number of periods (n)= 5*4= 20 semesters
Interest rate (i)= 0.05/4= 0.0125
To calculate the Future Value, we need to use the following formula:
FV= PV*(1 + i)^n
FV= 3,000*(1.0125^20)
FV= $3,846.11
Three paintings are shaped like an 8-foot square a 7-foot by 4-foot rectangle and a triangle with 6-foot base and height of 7 feet. If those paintings are hung together on the outside of the building how much of the building s wall they cover together ?
Answers
Answer:
113 square feet
Step-by-step explanation:
the total area covered can be determined by adding the area of the rectangle, triangle and square together
Area of a square = length² = 8² = 64 ft²
Area of a rectangle = length x width = 7 x 4 = 28 ft²
Area of a triangle = 1/2 x base x height = 1/2 x 6 x 7 = 21 ft²
64 + 28 + 21 = 113 ft²

The standard form:
y = ax² + bx + cPairs given:
(0, 0), (2, 4), (4, 0)Substitute values of x and y and work out the values of a, b and c.
1. Point (0, 0)
0 = a(0)² + b(0) + c ⇒ c = 02. Point (2, 4)
4 = a(2)² + b(2) ⇒ 4a + 2b = 4 ⇒ 2a + b = 2 ⇒ b = 2 - 2a3. Point (4, 0)
0 = a(4)² + b(4) ⇒ 16a + 4b = 0Substitute b and solve for a:
16a + 4(2 - 2a) = 016a + 8 - 8a = 08a = -8a = -1Find b:
b = 2 - 2(-1) = 2 + 2 = 4The function is:
