Answer:

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°

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.

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.

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.

Answer:

the board gets cut into two pieces

Step-by-step explanation:

5/14 is half of 5/7

Answer:

I do believe the answer is 2

Step-by-step explanation:

you need a common denominator so you multiply 5/7 by two to make 7, 14. What you do to the bottom you do to the top so your fraction turns into 10/14. She cuts pieces that are 5/14 long so 10/14-5/14=5/14-5/14=0 so she cuts 2 pieces

Answer:

B:  1

Step-by-step explanation:

I'm not sure what kind of given information that is, but here is my explanation:

f(x) = g(x) and values for both are given, so we combine their contents into one function: 3 - 6x = 5x - 8. Add 6x on both sides then add 8 on both sides, that'll get you 11x = 11. Divide both sides by 11 and you'll get x = 1.

Answer:

x=0   y=0

Step-by-step explanation:

3x + y = -7y = x

cancel out all y's

3x+ y(0) = -7(0) = x

3x  =x

-x    -x

2x = 0

divide both sides by 2

x=0

3x + y = -7y =x

cancel out all x's

3(0) +y = -7y = x(0)

y=-7y

-y  -y

0 = -7y

divide both sides by -7

y=0

hope this helps!

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

Answer:

∠ STR = 64°

Step-by-step explanation:

Since RS = ST then the triangle is isosceles and the base angles are congruent, that is

∠ STR = ∠ SRT , then

∠ STR = [tex]\frac{180-52}{2}[/tex] = [tex]\frac{128}{2}[/tex] = 64°

Answer:

Step-by-step explanation:

∠STR = 180 - 52

Answer:: i think its 5 im not sure

Step-by-step explanation:

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

Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Step-by-step explanation:

Answer:

range is the biggest number minus the smallest

Answer:

500

Step-by-step explanation:

125 is 25%

125 x 4 = 100% = 500

500 because if 125 is 25% of the toal then all we need to do is multiply 125 by 4.

Answer:

1/4 pls mark brainliest

Step-by-step explanation:

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 + 2nπ   or   θ + π/4 = 3π/4 + 2nπ

(where n is any integer)

θ = 2nπ   or   θ = π/2 + 2nπ

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

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.
