A man knows that his apple tree is 51 ft high. At 11:00 am the tree casts a shadow of 68 ft. What is the angle of elevation of the sun? Round to the nearest tenth

Answers

Answer 1

Answer:

36.9 degrees

Step-by-step explanation:

This problem can be solved by drawing a right triangle and doing trigonometry. We can draw our triangle with a height of 51 and a base of 68. In order to find the angle from the ground to the sun we can use arctangent (tan^-1). Since tan(angle)=opposite/adjacent we can find the angle by doing angle=tan^-1(51/68)

he airplane Li’s family will be flying on can seat up to 149 passengers. If 96 passengers are currently on the plane, which inequality can be used to determine how many more people can board?
96 + x Less-than-or-equal-to 149
96 + x Greater-than-or-equal-to 149
96 + x > 149
96 + x < 149

Answers

Answer: Choice A)  96 + x ≤ 149

This is the same as saying "96 + x less than or equal to 149"

====================================================

Explanation:

We start with 96 people already on board. We add on x more people. The x is a placeholder for a positive whole number.

In total, we have 96+x people on the plane. This total must not exceed the max capacity of 149. In other words, the largest value of 96+x is 149.

Since 96+x can be 149 or smaller, we can say 96+x ≤ 149

Answer:

The answer is A

Ms. Day went shopping last week and spent a total of $120. Blankets cost her $16 while pillows cost her $10. Altogether, she bought 9 items. How many of each item did Ms. Day end up buying?

Answers

Answer:

Ms. Day bought 5 blankets and 4 pillows.

Step-by-step explanation:

Let [tex]x[/tex] denotes number of blankets and [tex]y[/tex] denotes number of pillows.

Blankets cost her $16 while pillows cost her $10 and Ms. Day spent a total of $120.

[tex]16x+10y=120[/tex]

Divide this equation by 2.

[tex]8x+5y=60\,\,...(i)[/tex]

Ms. Day bought 9 items.

[tex]x+y=9[/tex]

Multiply this equation by 5.

[tex]5x+5y=45\,\,...(ii)[/tex]

Subtract [tex](ii)[/tex] from [tex](i)[/tex]

[tex]3x=15\\x=5[/tex]

Put [tex]x=5[/tex] in [tex]x+y=9[/tex]

[tex]5+y=9\\y=9-5\\y=4[/tex]

Therefore,

Ms. Day bought 5 blankets and 4 pillows.

Answer:

y = 4

x = 5

y = 2

x = 1

x = 8

Step-by-step explanation:

to find y-intercepts, set x = 0

to find x-intercepts, set y = 0

1.)   4(0) + 5y = 20

     5y = 20

      y = 4 -------> y-intercept

2.)   4x + 5(0) = 20

      4x = 20

       x = 5 -------> x-intercept

3.)   2(0) + y = 2

      y = 2 -------> y-intercept

4.)    2x + 0 = 2

       x = 1 -------> x-intercept

5.)    x - 2(0) = 8

       x = 8 -------> x-intercept

Answer:

4x+5y=20 the answer is below

x= −5/4y+5

y= −4/5x+4

2x+y=2 the answer is below

x= −1/2y+1

y=−2x+2

x-2y=8 the answer is below

x=2y+8

y=1/2x−4

Step-by-step explanation:

Let's solve for x.

4x+5y=20

Step 1: Add -5y to both sides.

4x+5y+−5y=20+−5y

4x=−5y+20

Step 2: Divide both sides by 4.

4x/4 = −5y+20/4

x= −5/4y+5

Answer:

x= −5/4y+5

Let's solve for y.

4x+5y=20

Step 1: Add -4x to both sides.

4x+5y+−4x=20+−4x

5y=−4x+20

Step 2: Divide both sides by 5.

5y/5 = −4x+20/5

y= −4/5x+4

Answer:

y= −4/5x+4

Let's solve for x.

2x+y=2

Step 1: Add -y to both sides.

2x+y+−y=2+−y

2x=−y+2

Step 2: Divide both sides by 2.

2x/2= −y+2/2

x= −1/2y+1

Answer:

x= −1/2y+1

Let's solve for y.

2x+y=2

Step 1: Add -2x to both sides.

2x+y+ −2x=2+ −2x

y=−2x+2

Answer:

y=−2x+2

Let's solve for x.

x−2y=8

Step 1: Add 2y to both sides.

x−2y+2y=8+2y

x=2y+8

Answer:

x=2y+8

Let's solve for y.

x−2y=8

Step 1: Add -x to both sides.

x−2y+−x=8+−x

−2y=−x+8

Step 2: Divide both sides by -2.

−2y −2=−x+8−2

Hope this helps!

Plz, Mark Brainliest!

The interest after 8 years is $240 and the balance after 8 years is $540.

What is Simple interest?

Simple interest is calculated by multiplying the daily interest rate by the principal, by the number of days that elapse between payments.

Given that, You deposit $300 in a savings account. The account earns 10% simple interest per year.

SI = P*R*T/10

Where P = principal

R = rate

T = time

a) The interest earned after 8 years:-

SI = 300*10*8/100 = $240

b) The balance after 8 years:-

Amount = 300+240 = $540

Hence, The interest after 8 years is $240 and the balance after 8 years is $540.
