Step-by-step explanation:

sinA=p/h

sinA=12/15

A=sin-¹(4/5)=53.13=53°

<CAB=53°

The measure of ∠CAB is 53°.

The trigonometric function, which comprises the sine, cosine, tangent, cotangent, secant, and cosecant, is one of the six mathematical operations used to describe the side ratios of right triangles (csc).

As per the given data:

From the given diagram, we can clearly understand that the triangle is a right-angled triangle which is right-angled at C.

We have to find out the measure of ∠CAB.

The lengths of the sides BC and AB is also given in the diagram.

For finding out the measure of ∠CAB we can consider BC as the perpendicular and AB as the hypotenuse, and then we have to use the appropriate trigonometric ratio.

The length of the perpendicular BC = 12 units

The length of the hypotenuse AB = 15 units

For relating perpendicular and hypotenuse, we can use the sin trigonometric ratio.

sinθ = Perpendicular / Hypotenuse

sinθ = BC / AB

sinθ = 12 / 15

sinθ = 4 / 5

θ = 53°

The measure of ∠CAB is 53°.

Hence, The measure of ∠CAB is 53°.

Answer:

5√5

Step-by-step explanation:

Hypotenuse (h) = 15

perpendicular (p) = 10

base (b) = ?

We know by using Pythagoras theorem

b = √h² - p²

= √ 15² - 10²

= √ 125

= 5√5

Hope it will help :)

Answer:

≈11.2

Step-by-step explanation:

a²+b²=c²

10²+b²=15²

100+b=225

-100 on both sides

b= √125= 11.2

Answer:

D

Step-by-step explanation:

This is because if u subsitute x with 17, 17x5 is 85 and 85+95= 180

[tex]\color{plum}\tt\bold{(D) \: 17}[/tex]

Given :

▪︎Angle (5x)° and angle 95° are supplementary angles.

Which means :

[tex] = \tt5x + 95 = 180[/tex]

[tex] = \tt5x = 180 - 95[/tex]

[tex] = \tt5x = 85[/tex]

[tex] \hookrightarrow\tt \color{plum}x = 17[/tex]

Thus, the value of x = 17

Let us check whether or not we have found out the correct value of x by placing 17 in the place of x:

[tex] =\tt5 \times 17 + 95 = 180[/tex]

[tex] =\tt 85 + 95 = 180[/tex]

[tex] =\tt 180 = 180[/tex]

Since the sum of both angles is equivalent to 180[85+95=180], we can conclude that we have found out the correct value of x.

Therefore, the correct option is (D) 17

Answer:

The standard deviation of the given data set

 σ =  2.135

Step-by-step explanation:

Step(i):-

Given numbers are 4 2 8 5 7

Mean of the numbers

 [tex]= \frac{4+2+8+5+7}{5}[/tex]

= 5.2

The mean of the numbers (μ) = 5.2

Step(ii):-

x        :    4         2       8        5         7

x-μ     :   -1.2   -3.2     2.8    -0.2     1.8

(x-μ)² :   1.44    10.24  7.84  0.04    3.24

The standard deviation of the given data

            σ = √Σ( x-μ)² / N

           σ  = [tex]\sqrt{ \frac{1.44+10.24+7.84+0.04+3.24}{5}}[/tex]

            σ =  2.135

Answer:

$2400

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year,

putting time into years for simplicity,

36 months ÷ 12 months/year = 3 years,

then, solving our equation

I = 10000 × 0.08 × 3 = 2400

I = $ 2,400.00

The simple interest accumulated

on a principal of $ 10,000.00

at a rate of 8% per year

for 3 years (36 months) is $ 2,400.00.

Step-by-step explanation:

No, The coach does not have enough money to buy a bat bag for each player.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

There are 12 players on a softball team.

The coach has $605 to buy bat bags for all of the players.

Each bat bag costs = $55

Now,

Since, There are 12 players on a softball team.

And, Each bat bag costs = $55

So, The total cost of bag for 12 players = $55 x 12

                                                            = $660

Since, The coach has $605 to buy bat bags for all of the players.

And, $605 < $660

Thus, The coach does not have enough money to buy a bat bag for each player.

I was thinking the measurement for ;length should be 2.5n + 8 feet since width is 6n -2.5 feet , but you gave 2.5+ 8 feet, so i will solve it in both ways

Answer:  Perimeter =  5 + 12n + 11 feet ; Perimeter =  17n+ 11 feet

Step-by-step explanation:

Using Length = 2.5+ 8 feet,

Perimeter of  a rectangle is calculated as 2( l+ b)

Given that width=6n - 2.5 feet

length =2.5 + 8 feet

Perimeter =2( l+ b)= 2L + 2B

Perimeter= 2(2.5 + 8feet ) + 2( 6n - 2.5 feet)

Perimeter = 5 + 16feet + 12n - 5feet

Perimeter =  5 + 12n + 11 feet

Using Length = 2.5n+ 8 feet,

Perimeter of  a rectangle is calculated as 2( l+ b)

Given that width=6n - 2.5 feet

length =2.5n+ 8 feet

Perimeter =2( l+ b)= 2L + 2B

Perimeter= 2(2.5n + 8feet ) + 2( 6n - 2.5 feet)

Perimeter = 5n + 16feet + 12n - 5feet

Perimeter =  5n + 12n + 11 feet

Perimeter =  17n+ 11 feet

Answer:

yes, the given relation is a function.

Step-by-step explanation:

The given relation is

{(–3, –2), (–1, 0), (1, 0), (5, –2)}

A relation is called function if each element of the domain is paired with exactly one element of the range.

It means for each value of x there exist a unique value of y.

In the given relation for each value of x there exist a unique value of y.

Therefore the required solution is yes and this relation is a function.

Answer:

26.4 km/hr

Step-by-step explanation:

Sofia and Diego drive to work.

For Sofia

We convert miles to km

Sofia drives 72 miles in 1.5 hours.

1 mile = 1.6 km

72 miles = x

x = 72 × 1.6 km

x = 115.2 km

We find the speed in km/hr

Speed = Distance /Time

= 115.2km/1.5 hours

= 76.8 km/hr

For Diego

Diego drives 126 km in 2 hour 30 min.

Speed = Distance/Time

Time = 2 hour 30 min = 2.5 hours

Speed = 126km/2.5 hours

= 50.4 km/hr

The difference between their average speeds in km/h is calculated as:

76.8 km/hr - 50.4 km/hr

= 26.4 km/hr

Given that a binomial is multiplied by a trinomial.

A binomial means containing two terms normally

When a binomial is multiplied by a trinomial getting a product of degree 5 is only occasional and not always.

Yes, Tony is correct.

Here,

Lila rewrote 10/25 as 40/100 and represented it with the given picture.

And, Tony thinks this fraction is also equal to 2/5.

We have to find that, Tony is correct or not.

What is Fraction?

Fractions represent the parts of a whole or collection of objects.

Now,

In this picture there are total 25 square and shaded squares are 10.

So, it can be written in form of fraction as;

[tex]Fraction = \frac{Number of shaded squares}{total number of squares} =\frac{10}{25}[/tex]

Since, Lila rewrote 10/25 as 40/100 and represented it with the given picture.

And, Tony thinks this fraction is also equal to 2/5.

Then, we have to get the fraction = 10/25

After simplifying the fraction we get;

[tex]\frac{10}{25} = \frac{2}{5}[/tex]

Hence, Tony is correct.
