Please help it’s urgent!! Find the sine, cosine and tangent of angle B. Leave answers as reduced fractions.

Answer:

Step-by-step explanation:

Given

[tex]\log _{10}\ 50=1.69897[/tex]

and we know that

[tex]\log _a\ a=1[/tex]

therefore

[tex]\Rightarrow \log _{10}\ 10=1[/tex]

and [tex]\Rightarrow \log _{10}\ 100=\log _{10}\ 10^2=2[/tex]

and [tex]50[/tex] lies between [tex]10[/tex] and [tex]100[/tex] . So, its value must lie between [tex]1[/tex] and [tex]2[/tex]

Answer:

Step-by-step explanation:

if m is the slope of given line.

Then eq. of parallel line through (-4,-6) is

y+6=m(x+4)

Answer:

y=-6

Step-by-step explanation:

The line shown is a horizontal line through the y-axis and has the equation y=4. A parallel line to it is a line that does not cross it. It will also have the form y=a where a is the y-coordinate of its points. The point (-4,-6) is on the line so y=-6 is the line.

Answer:

f(3) = 63

Step-by-step explanation:

f(x) = 4^x-1;

Let x =3

f(3) = 4^3 -1

     = 64-1

     =63

Answer:

f(3)=16

Step-by-step explanation:

This question asks us to find f(3). We have to find what f(x), or y is, when x is equal to 3.

f(x)=4^x-1

Substitute 3 in for x.

f(3)=4^3-1

First, subtract what is in the exponents.

f(3)=4^2

4^2 is the same as multiplying 4, 2 times.

4^2=4*4=16

f(3)=16

Answer:

$56.25

Step-by-step explanation:

We know that Max has just enough money to buy 3 tickets that each cost $18.75, so let's write the expression:

18.75 * 3

We just solve this by multiplication:

18.75 * 3 = $56.25

Max saved $56.25.

Answer:

$56.25

Step-by-step explanation:

His savings were equal to the cost of 3 tickets, therefore

Savings = 3 × 18.75

Savings = 56.25

Answer:

a.  x = 61 degrees.

Step-by-step explanation:

By the External angle of a Triangle Theorem:

116 = 55 + x

x = 116 - 55

x = 61 degrees.

Answer:

a) 61

Step-by-step explanation:

The classic way to do this is to subtract 116 from 180, then adding that result to 55 and subtracting this second result from 180.

But another way that I have discovered is to subtract 55 from 116. You will get the same answer of 61.

Answer:

7

Step-by-step

n=smallest integer; n+1=second integer; n+2=third integer; n+3=fourth integer

n+(n+1)+(n+2)+(n+3)=34

4n+6=34

4n=28

n=7 ANSWER: The smallest integer is 7

CHECK:

7+8+9+10=34

34=34

the least of the four consecutive integers is 7.

Let's denote the four consecutive integers as x, x + 1, x + 2, and x + 3.

According to the given information, the sum of these four consecutive integers is 34:

x + ( x + 1 ) + ( x + 2 ) + ( x + 3 ) = 34

Simplifying the equation:

4 x + 6 = 34

Subtracting 6 from both sides:

4 x = 28

Dividing both sides by 4:

x = 7

The four numbers are 7, 8, 9, 10

Therefore, the least of the four consecutive integers is 7.

Answer:

91 students passed the test.

Step-by-step explanation:

130 / 10 = 13

13 x 3 = 39

130 - 39 = 91

Answer:

91 students passed the test.

Step-by-step explanation:

We need to find 10% of 130.

130÷10=13

Then we need to make it 30% in order to see the amount of students that failed the test.

13×3=39

Then we need to do 130 - 39 (The whole class- 30%)

130-39=91

Answer:

B, 5x - 3 = 12

Step-by-step explanation:

3 less means subtracting, it's going to be -3.

It says 3 less than five times a number, meaning we don't know the number, so we can put it as x.

3 less means your subtracting from something, which would make it 5x - 3.

Finally, they state that it equals 12, making the equation 5x - 3 = 12.

Answer:

$1193

Step-by-step explanation:

First we need to find the volume of one pedestal, that has a cylindrical part and a cubic part.

The volume of the cylindrical part is:

V1 = pi * r^2 * h

The radius is half the diameter, so r = 8/2 = 4 in. So the volume is:

V1 = pi * 4^2 * 3 = 48pi in3

The volume of the cubic part is:

V2 = side^3 = 8^3 = 512 in3

So the total volume of the pedestal is:

V = V1 + V2 = 512 + 48pi in3

If we want 15 pedestals, we have a total volume of:

15 * V = 15 * (512 + 48pi) = 9941.9467 in3

As each cubic inch costs $0.12, we just need to multiply the volume by the price to find the total cost:

Cost = 9941.9467 * 0.12 = $1193.03

Rounding to the nearest dollar, we have a cost of $1193

Answer:

Reflection

Step-by-step explanation:

Answer :

9 sides

Explanation:

Step 1

Since the interior angle is 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.

Step 2

Method 2: Since the exterior angle is 140°

The sum of the interior angles = (2n - 4) × right angles.

So 140n =(2n - 4) ×right angles, or we can also say

140n =(2n - 4) × 90

140n = 180n - 360

40n = 360

Divide both sides of the equation by 40

n = 9 sides.

n = 9 sides.Hence the number of sides is 9 sides.

Answer:

Step-by-step explanation:

the volume of a rectangle is length x width x height, so the volume of the first rectangle is 2700.

the square has a length and width of 15 with a missing height. because they have the same volume, you can plug in the length and width of the square with the volume of the prism to find the height

v = length x width x height

2700 = (15)(15)h

2700/225 = h

the height is 12

Answer:

Therefore the expression that finds the coterminal angles is:

[tex]coterminal = 126\º \pm 360[/tex]

Step-by-step explanation:

Coterminal angles are angles that finish at the same line. Therefore in order to find the coterminal angles with 126º we need to add or subtract a angle of 360º. So the expressions are:

coterminal angle = 126º + 360º = 486º

coterminal angle = 126º - 360º = -234º

Therefore the expression that finds the coterminal angles is:

[tex]coterminal = 126\º \pm 360[/tex]

Answer:

23/21 liters

Step-by-step explanation:

Celia drank

Before going jogging=2/3

After jogging=3/7

Total amount of water drank by Celia=2/3+3/7

L.C.M of the denominators 3 and 7 is 21

=14+9/21

=23/21

=1 2/21 liters

Answer: 23/21

Step-by-step explanation:

Litre of Water drank before jogging = 2/3

Litre of water drank after jogging = 3/7

The total amount of water drank altogether ;

2/3 + 3/7

The lowest common factor of 3 and 7 = 21

= (14 + 9)/21

= 23/21 litres

= 1 2/21 litres [1 whole number 2/21]
