Answer 1

Answer:

Answer A

Step-by-step explanation:

Angle A = 180 - 26 - 90 (90 right angle)

The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

cos ( A)= adj/hyp

Cos (26) = a / 13

a = 13* Cos (26)

a= 11.7

A large university accepts ​60% of the students who apply. Of the students the university​ accepts, 50​% actually enroll. If 10,000 students​ apply, how many actually​ enroll?

Answers

we need to find 1% of 10000 first

so we divide 10000:100= 100 (that's 1%)

to find the 60% which will be accepted we multiply 100 × 60 = 6000 students accepted

of those 6000 we need to find 50% which is ½ so we basically just divide by 2, aka 6000 : 2 = 3000 people which will be enrolled

Suppose you invest $2000 at annual interest rate of 4.5 % How much money do you have in the account after five years?

Round two decimal places.

compounded quarterly $ _____

compounded semi-annually $ _____

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

To find the amount we use the formula:

[tex]A=P\cdot \left(1+\frac{r}{n}\right)^{nt}[/tex]

Here:

A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

Given

P=$2000

r=4.5%

n=4

t = 5 years

Calculating compounded quarterly

After plugging in the values

[tex]A=2000\left(1+\frac{4.5\%\:}{4}\right)^{4\cdot \:5}[/tex]

[tex]A=2000\left(1+\frac{0.045}{4}\right)^{4\cdot \:5}[/tex]

[tex]A=2000\cdot \frac{4.045^{20}}{4^{20}}[/tex]

[tex]A=\frac{125\cdot \:4.045^{20}}{2^{36}}[/tex]

[tex]A = 2,501.50[/tex]

Thus, If you deposit $2000 into an account paying 4.5% annual interest compounded quarterly, you will have $2501.50 after five years.

Calculating compounded semi-annually

n = 2

[tex]A=2000\left(1+\frac{4.5\%\:}{2}\right)^{2\cdot \:5}[/tex]

[tex]A=2000\left(1+\frac{0.045}{2}\right)^{2\cdot \:5}[/tex]

[tex]A=2000\cdot \frac{2.045^{10}}{2^{10}}[/tex]

[tex]A = 2,498.41[/tex]

Thus, If you deposit $2000 into an account paying 4.5% annual interest compounded semi-annually, you will have $2,498.41  after five years.

Two shopkeepers take 4 minutes and 5 minutes respectively to serve customers. How many customers will the two serve in 5 hours?

Answers

The shopkeeper who takes 4 minutes will serve 75 customers over five hours and the shopkeeper who takes 5 minutes will serve 50 customers over five hours. At this rate, they will have served 125 customers together.

This can be solved by dividing the number of minutes the shopkeeper takes by the number of minutes in an hour, 60. This multiplied by five will give the answer for five hours but if you replace the five with any number it will answer for that number of hours (EX: replacing the 5 in this with a 7 will solve how many each shopkeeper can do in 7 hours). Then you should add the two totals for the two shopkeepers and you will get the total the both of them served.

Answers

Full question :

Kyra is using rectangular tiles of two types for a floor design. A tile of each type is shown below: Two rectangular tiles, rectangle PQRS with vertices at P 5, 7. Q is at 9, 7. R is at 9, 12. S is at 5, 12 . Rectangle JKLM with vertices J 4, 5. K is at 6, 5. L is at 6, 10. M is at 4, 10. Which statement is correct? The two tiles are not similar because segment PQ is to segment QR is 4:5 and segment JK is to segment LM is 2:1. The two tiles are not similar because segment SP is to segment SR is 5:4 and segment MJ is to segment ML is 5:2. The two tiles are similar because segment PQ is to segment QR is 4:5 and segment JK is to segment KL is also 4:5. The two tiles are similar because segment SR is to segment ML is 2:1 and segment PQ is to segment JK is also 2:1.

Answer:

The two tiles are not similar because segment SP is to segment SR is 5:4 and segment MJ is to segment ML is 5:2.

Step-by-step explanation:

Given vertices which will be our points on the graph to trace the rectangular shapes:

For the first rectangular shape PQRS

P(5,7)

Q(9,7)

R(9,12)

S(5,12)

For the second rectangular shape JKLM

J(4,5)

K(6,5)

L(6,10)

M(4,10)

From the above we can find that the two tiles are not similar if we calculate using their x, y coordinates points(vertices) on the graph.

We can see from the options given that only the second option is correct because:

Line SP ratio to line SR in rectangle PQRS= 5:4

since SP=12-7=5 and SR=9-5=4

Therefore SP:SR = 5:4

Line MJ ratio to line ML in rectangle JKLM= 5:2

Since MJ= 10-5=5 and ML= 6-4=2

Therefore MJ:ML =5:2

In a unit​ circle, the radian measure of the central angle is equal to the length of the ________. A:Raduis B:intercepted arc C:Circumfrence D:Diameter

Answers

Answer:

B:intercepted arc

Step-by-step explanation:

Recall from the knowledge of geometry:

That arc (s) = θ * r(1)

Here;

θ is known as the central angle which is measured in radians

r is the radius of the dimensionless

Hence, suppose the unit circle have a radius of 1 m length. Then, it is pertinent to understand that the arc will also varies directly proportional to the central angle.

Sheryl has a Christmas lighting project. She is going to put lights around outside of 15 windows with a height of 4 feet and a width of 2 feet. She also wants to put lights around 3 garage doors that are 9 ft wide and 9 ft long. How many feet of Christmas lights will be needed

Answers

She will need 288 ft of Christmas lights

Step by Step:
First we find how many feet is needed to go around 1 window. We do this by adding up all four of its sides.
4+4+2+2= 12
Because there are 15 windows be multiply the feet needed for 1 window by 15.
12•15=180
Repeat the first two steps for the garage doors to find that she needs 108ft of lights for 3 garage doors and add the feet needed for the windows to the feet needed for the garages

sin(θ) + cos(θ) = 1

Divide both sides by √2:

1/√2 sin(θ) + 1/√2 cos(θ) = 1/√2

We do this because sin(x) = cos(x) = 1/√2 for x = π/4, and this lets us condense the left side using either of the following angle sum identities:

sin(x + y) = sin(x) cos(y) + cos(x) sin(y)

cos(x - y) = cos(x) cos(y) - sin(x) sin(y)

Depending on which identity you choose, we get either

1/√2 sin(θ) + 1/√2 cos(θ) = sin(θ + π/4)

or

1/√2 sin(θ) + 1/√2 cos(θ) = cos(θ - π/4)

Let's stick with the first equation, so that

sin(θ + π/4) = 1/√2

θ + π/4 = π/4 + 2   or   θ + π/4 = 3π/4 + 2

(where n is any integer)

θ = 2   or   θ = π/2 + 2

We get only one solution from the second solution set in the interval 0 < θ < 2π when n = 0, which gives θ = π/2.

i need help solving this right triangle, please!​

We know the opposite and adjacent sides of angle B, so we can use the inverse tangent to solve for its value.
tan(B)^-1 = 3/4
B = 64.4 degrees

Answer:

∠B = 36.87°

Step-by-step explanation:

since its a right triangle, use Pythagorean to solve for c

c² = 3² + 4²

c = √25

c = 5

now use law of sine

sinB = sinC

  b         c

sin(B) = sin(90)

  3            5

5*sin(B) = 3*sin(90)

sin(B) = 3*sin(90)

                  5

∠B = sin⁻¹(0.60)

∠B = 36.87°

Lúcia is using energy at a rate of 420 kilocalories (kcal) per hour (h) ice skating.

Answers

Answer:

7000 cal/min

Step-by-step explanation:

It is mentioned that, Lucia is using energy at a rate of 420 kilo calories per hour ice skating

We know that,

1 kilo calories = 1000 calories

Using unitary method :

420 kilo calories = 420,000 calories

Also,

1 hour = 60 minutes

In this case, Lucia is using energy per 60 minutes =  420,000 calories. So,energy used by her per minute is :

[tex]E=\frac{420000}{60} =7000 calories[/tex]

Hence, Lucia is using 7000 calories per minute.

2x = 0

divide both sides by 2
