Find the Discount % if the OriginalPrice is $15 and the Sale Price is $14.25.
Answers
Answer:
5%
Step-by-step explanation:
15-14.25/15
original - sale price divided by original = percent change
15-14.25/15 = 0.75/15 = 0.05 = 5%
15-14.25=0.75
0.75/15= 0.05
To turn into percentage do 0.05x100 so answer is 5% discount
Find the value of ∠R
Answers
Answer:
∠ R = 30°
Step-by-step explanation:
The secant- secant angle R is half the difference of its intercepted arcs, so
∠ R = [tex]\frac{1}{2}[/tex] (103 - 43)° = [tex]\frac{1}{2}[/tex] × 60° = 30°
An arctic wooly bear caterpiller lives for 7 years and spends 90% of its life frozen. How many days of its life is the arctic wolly bear frozen.
Answers
Answer:
The arctic wolly bear is frozen 2,299.5 days of its life.
Step-by-step explanation:
With the information provided, first, you have to calculate the number of days in 7 years by multiplying 7 years for 365 that is the number of days in a year:
7*365=2,555
Then, you have to calculate 90% of 2,555 since the statement indicates that the arctic wooly bear caterpiller spends 90% of its life frozen:
2,555*90%=2,299.5
According to this, the answer is that the arctic wolly bear is frozen 2,299.5 days of its life.

Al precio de p dólares por unidad, se venden x unidades de cierto artículo al mes en el mercado con p=50-0.5x ¿Cuántas unidades como mínimo se deben vender cada mes con el objetivo de tener ingresos de por lo menos de 1.200 dólares?
Answers
Answer:
Se debe vender un mínimo mensual de 40 artículos para tener un ingreso mínimo de 1.200 dólares.
Step-by-step explanation:
De acuerdo con el enunciado, [tex]x[/tex] es la cantidad mínima de artículos a un precio de [tex]p[/tex]. Además, los ingresos totales deben ser de un mínimo de 1200. En consecuencia, tenemos el siguiente sistema de ecuaciones:
[tex]x \cdot p = 1200[/tex] (1)
[tex]p = 50-0.5\cdot x[/tex] (2)
Aplicando (2) en (1), tenemos la siguiente ecuación polinómica:
[tex]x\cdot (50-0.5\cdot x) = 1200[/tex]
[tex]50\cdot x -0.5\cdot x^{2} = 1200[/tex]
[tex]0.5\cdot x^{2}-50\cdot x +1200 = 0[/tex] (3)
Por la Fórmula de la Cuadrática tenemos las raíces del polinomio:
[tex]x_{1} = 60[/tex], [tex]x_{2} = 40[/tex]
De acuerdo con el resultado anterior, se debe vender un mínimo mensual de 40 artículos para tener un ingreso mínimo de 1.200 dólares.

The radius of a circle is 3/4 inches. How many inches is the diameter?
Answers
Step-by-step explanation:
Given
In a circle
Radius (r) = 3 / 4 inches
Diameter (d)
= 2 * r
= 2 * 3 /4
= 3 /2 inches
Hope it will help :)❤
The diameter of a circle with a radius of 3/4 inches is 6/4 inches.
We are given that;
The radius of a circle = 3/4 inches
Now,
The diameter of a circle is twice the radius of the circle. Therefore, to find the diameter of a circle with a radius of 3/4 inches, we need to multiply 3/4 by 2. We can do this by multiplying the numerators and the denominators:
(3/4) x 2 = (3 x 2)/(4 x 2) = 6/8
We can simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2:
6/8 = (6/2)/(8/2) = 6/4
Therefore, by the circle the answer will be 6/4.

Find the measure of the indicated arc
Answers
Answer:
200 degrees.
Step-by-step explanation:
By theorem of inscribed angle...
The measure of an inscribed angle is half the measure of the intercepted arc. [Theorem]
therefore, m(angle J) = half of m(arc CDE)
therefore, m(arc CDE) = 2 * m(angle J)
therefore, m(arc CDE) = 2 ( 100)
therefore, m(arc CDE) = 200 degrees.

Answers
Answer:
B
Step-by-step explanation:
Yes, it is. The set of rational numbers is closed for all the four operations, so x+y, x-y, x*y and x/y are rational too. And it is easy to demonstrate. A rational number can be expressed as a fraction of two integers. So, x can be expressed as a/b and y as c/d. Hence x+y = a/b + c/d = (ad+bc)/bd, which, as fraction of two integers, is rational.

A garden is made up of two squares and a quarter circle. What is the area of the garden?
Round to the nearest hundredths
____ square feet
Answers
9514 1404 393
Answer:
100.27 ft^2
Step-by-step explanation:
The area of each square is ...
A = s^2 = (6 ft)^2 = 36 ft^2
The area of the 1/4 circle is ...
A = 1/4πr^2 = 1/4π(6 ft)^2 = 9π ft^2 ≈ 28.27 ft^2
__
The area of the garden is the sum of the areas of the quarter circle and the two squares:
A = 28.27 ft^2 + 2×36 ft^2 = 100.27 ft^2
The area of the garden is about 100.27 square feet.
