Answer 1

Answer:

169. (m^2)

Step-by-step explanation:

lets first look at the smaller box. 7 x 7 is 49 so we have that answer. then 7 x 20 is 120. add those together and you get 169.

Answer 2

Answer:

The area of the composite figure is 189 square meters.

Step-by-step explanation:

First, partition the composite figure into 2 distinct shapes: a rectangle and a square on the top.

The formula for finding the area is: A = lw, or Area = length * width.

Area for figure number 1 (the square): 7 * 7 = 49

Area for figure number 2 (the rectangle): 20 * 7 = 140

Now, just add up both figures' areas, and find the answer:

140 + 49 = 189

I hope this somewhat helped. Have a great day!

Jesse collects data on his math scores on the last 12 tests and the number of hours he spent completing his math homework assignments and studying in the week before every test. He creates a scatter plot to show the data. The regression line shown on the graph best models the data on the scatter plot.

Based on the given model, how many hours in the week before the test does Jesse need to study to get a score of 90 on the test? Round your answer to the nearest hour.

Answers

Answer:

24 hours

Step-by-step explanation:

Using the two points on the regression line, let's find its equation.

Points:

(0, 30) and (8, 50)

The slope:

(50 - 30)/8 = 2.5

The y-intercept is

The equation:

y = 2.5x + 30

Solve for x if y = 90

90 = 2.5x + 302.5x = 60x = 60/2.5x = 24

The answer is 24 hours

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.

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.

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.

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.
