Marco would like to hang a banner over his shoe store. He has two ladders and would like to know how high above the ground each ladder will allow him to place the banner. A 13- foot ladder leans against the building and touches it at a point that is 11.3 feet above the ground.
what height would a 15-foot ladder touch the building if both ladders form the same angle with the ground? Make a sketch and round your answer to the nearest tenth

Answers

Answer 1
13 divided by 11.3 is 1.150442477876106. So 15 by 1.150442477876106 and you get 13.03846162772485. Just round it to the nearest tenth and you get 13.0.

Find the solution to the system: x=2y-7 and 4x+y=71

Answers

4*(2y-7)+y=71

8y-28+y=71

9y=71+28

y=99/9

So y=11

Again putting value of y in first equation

x=2*11-7

x=22-7

x=15

So value if x is 15 and y is 11

Find the measure of MN. please help!!!!

Answers

Given:

A circle with center O.

[tex]m\angle MOP=45^\circ, m\angle PON=85^\circ[/tex].

To find:

The measure of arc MN.

Solution:

We know that,

[tex]m\angle MON=m\angle MOP+m\angle PON[/tex]

[tex]m\angle MON=45^\circ+85^\circ[/tex]

[tex]m\angle MON=130^\circ[/tex]

The central angles in equal to the measure of the corresponding arc.

[tex]Arc(MN)=m\angle MON[/tex]

[tex]Arc(MN)=130^\circ[/tex]

Therefore, the measure of arc MN is 130 degrees.

Mr. Bayless invests $3500 in a savings plan. The savings account pays an
annual interest rate of 4.75% on the amount he put in at the end of the
year. How much will Mr. Bayless earn if he leaves his money in the savings
plan for 8 years and how much money will be in his savings plan at the end
of 8 years?

Answers

Answer:

Interest = $1330

Amount = $4830

Step-by-step explanation:

Given

Principal = $3500

Rate = 4.75%

Time T = 8 years

Interest =PRT/100

Interest = 3500*4.75*8/100

Interest = 35*4.75*8

Interest = $1,330

Hence the interest earned by Mr. Bayless is  $1,330

Amount after 8years = Principal + Interest

Amount after 8years = 3500+1330

Amount after 8years = $4830

Hence the amount after 8years is $4830

20/126=10/63

Answer:

10/63

Step-by-step explanation:

First, let's solve 4/9 * 5/7. Multiply the numerator first- 4*5=20. The denominator is 9*7=63. So, this equals 20/63. Now we need to find 20/63 * 1/2. We can cancel out the 2 on the denominator and divide 20 on the numerator by 2. So, you get 10/63 * 1/1, which is 10/63.

A house is losing value at a rate of 5.4% per year. In 2009, the house was worth $331,000. Find the value of the house in 2021.

Answers

Answer:

$169803

Step-by-step explanation:

Given data

rate of decrease = 5.4%

time = 2009-2021= 12years

P=  $331,000

Let us apply the compound interest formula

A=P(1-r)^t----------------note the minus sign because this is a decrease

A= 331000(1-0.054)^12

A= 331000(0.946)^12

A= 331000*0.513

A=$169803

Hence the value in 2021 is $169803

What is an equation of the line that contains the point (0, -5) and a slope of 1/4

Answers

Answer:

y=1/4x-5

Step-by-step explanation:

Answer:

y = 1/4x - 5

Step-by-step explanation:

y = mx + b is the equation of a straight line.

m = slope, b = y intercept. (y intercept is the point where the line of the graph crosses the y axis)

(0, -5) is the y intercept (if you were to graph this point, it would be on the y axis, fitting the previous description)

the slope is 1/4

replace each variable in the equation, and you get:

y = 1/4x - 5

Consider a reaction that connects the ends of a chain of carbons to form a ring. The closure of the ring results in the formation of a new chemical bond, with the bonding electrons going into a bonding sigma molecular orbital at a lower energy. Which of the following statements correctly describes the resulting enthalpy, entropy, and heat changes? Mark all that are correct. A. The entropy of the surroundings decreases (AS surr < 0) because the closure of the ring results in fewer conformations for the system. B. The system releases energy to the environment, because its internal energy decreases. C. The entropy of the surroundings increases (AS surr > 0) because the surroundings absorb heat released by the reaction, and become more disordered. D. The entropy of the system decreases (AS sys < 0) because the closure of the ring reduces the number of conformations the ring can adopt. E. The enthalpy or internal energy of the system decreases (AH sys < 0) because the electrons that form the bond enter an orbital that is at a lower energy. What was the name give.
