450 ft2
It’s not 420 I got it wrong

Answers

Answer:

396 ft²

Step-by-step explanation:

Area of the figure = area of the rectangle + area of the triangle

= L*W + ½*bh

L = 20 ft

W = 15 ft

b = 12 ft

h = 16 ft

Area of the figure = 20*15 + ½*12*16

= 300 + 96

= 396 ft²

First you need to find the second base (b2) by plugging all the values into the area of a trapezoid formula.

A= 1/2 (b1+b2)h

After plugging it in you will find that b2= 21.3.

The questions is asking perimeter so you add all the sides together...
14.4+18.5+14.7+21.3= 68.9 ft

Is the following graph exponential? Explain how you know.

Answers

Yes.
How to tell if a graph is exponential:
The graph passes through the point (0,1)
The domain is all real numbers.
The range is y>0.
The graph is increasing.
The graph is asymptotic to the x-axis as x approaches negative infinity.
The graph increases without bound as x approaches positive infinity.
The graph is continuous.

Layla and Jacob are taking a photography class. Layla took twice as many photos as Jacob, and Jacob took 10 fewer photos than Layla. This situation can be represented with the system y = 2x and y = x +10, which can be used to find the number of photos taken by Jacob x and the number of photos taken by Layla y. Solve using systems of equations by substitution

Answers

Answer:

x = 10; y = 20

Step-by-step explanation:

y = 2x

y = x +10

Substitute y of the second equation with 2x.

2x = x + 10

x = 10

y = 2x = 2(10)

y = 20

Answer: x = 10; y = 20

If one inch represents 6 feet, what dimensions would you use to make a scale drawing of a building 240 feet by 500 feet?

Answers

Answer: It would be 40 inches by 83 1/3 inches

Step-by-step explanation:

The dimensions on the scale drawings will be 40 inches by 83.34 inches.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that If one inch represents 6 feet. The dimensions of 240 feet by 500 feet in the scale drawing will be,

6 feet =  1 inch

1 feet = 1 / 6 inch

240 feet = ( 240 / 6 ) inches

240 feet = 40 inches

500 feet = ( 500 / 6 ) inches

500 feet = 83.34 inches

About 1.15 million people live in a circular region with a population density of 18075 people per kilometer. Find the radius of the region

Answers

Answer:

r = 5 km

Step-by-step explanation:

Given that,

The population in a circular region = 1.15 million

The population density of the region = 18075 people per kilometer

We need to find the radius of the region.

We can find the area of circular region i.e.

[tex]A=\dfrac{P}{d}\\\\A=\dfrac{1.15\times 10^6}{18075 }\\A=63.6\ km^2[/tex]

We know that the area of a circular region is given by :

[tex]A=\pi r^2\\\\\pi r^2=63.6\\\\r=\sqrt{\dfrac{63.6}{\pi}} \\\\r=4.49\ km[/tex]

or

r = 5 km

So, the radius of the region is equal to 5 km.

Using the figure below, what is the trigonometric ratio of cos C?

Answers

Answer:

8/9 (choice b)

Step-by-step explanation:

The trigonometric ratios are based on the ratios of different sides.

If you remember SOH CAH TOA =

sine (sin) opposite hypotenuse

cosine (cos) adjacent hypotenuse

tangent (tan) opposite adjacent

__________________________

This is a nuemonic for these ratios.

the opposite side is the side that is directly across from the reference angle, the hypotenuse is the longest side, and the adjacent side is the side other than these two.

So cos C = adjacent side / hypotenuse side.

Since 18 is greater than 16 and 9, 18 is the hypotenuse.

the adjacent side is the side other than the opposite side and the hypotenuse which is 16

therefore cos C = 16 / 18 = 8 / 9.

Hazel invested part of a Php10,000 inheritance in stocks paying 6.5%
simple interest annually. She invested the rest in bonds paying 4.25% simple
interest annually. If Hazel will receive Php 582.50 in interest after one year,
how much did she invest in stocks? How much did she invest in bonds?​

Answers

Answer:

she invested $7013.33 in stocks and she invested $2986.7 in bonds?

Step-by-step explanation:

Let the amount invested in the stock= X

Let the amount invested in the bond= Y

For quantity equation,

X + Y = 10000 ............eqn(1)

✓We are told inheritance in stocks paying 6.5% simple interest = 0.065X

✓we are told She invested the rest in bonds paying 4.25% simple interest= 0.0425Y

The interest equation can be written as

0.065X + 0.0425Y = 582.50.........eqn(2)

We can make X subject of formula from eqn(1)

X= 10000 - Y

Substitute into eqn (2)

0.065(1000-Y) + 0.0425Y= 582.50

Multiply through by 10000

650(10000 - Y) + 425Y = 5825000

6500000 - 650Y + 425Y =5825000

Y= 2986.66

If we substitute Y into (X + Y )= 10000

X+2986.66= 10000

X= 7013.33

hence, she invested $7013.33 in stocks and she invested $2986.7 in bonds?

They employed less-experienced teachers than the Anglo schools. Chicano children were given shabbier books and equipment than their white peers and were taught in more crowded classrooms. Perhaps the greatest difference between the schools, however, was in their curricula. While geometry and biology were taught at the Anglo schools, classes at the Mexican schools focused on teaching boys industrial skills and girls domestic tasks.Many Anglo educators did not expect, or encourage, Chicano students to advance beyond the eighth grade. Instead, the curriculum at the Mexican schools was designed, as one district superintendent put it, to help these children take their place in society.Compare and contrast the Mexican schools to the Anglo schools.
