HOW DO I DO THIS[tex]j[/tex]

Answer:

Step-by-step explanation:

25.95 x 3 = 77.85

13.95 x 4 = 55.8

77.85 + 55.8 = 133.65

With Cos s=-2/5 and sin t=4/5, s and t are in quadrant 4,  cos(s+t) and cos(s-t) is mathematically given as

cos(s+t)= 0.493

cos(s-t)= 0.97321

Question Parameter(s):

Cos s=-2/5 and sin t=4/5, s and t are in quadrant 4

Generally, the equation for the s and t as functions of the 4 qudrants is mathematically given as

cos(s+t) = cos(s)*cos(t) - sin(s)*sin(t)

Therefore

cos(s+t)= -4/5 * [tex](-\sqrt{21}[/tex]/5) - (-3/5)*(-2/5)

cos(s+t)= 4*[tex]\sqrt{21}/[/tex]25 - 6/25

cos(s+t)= 0.493

In conclusion,

cos(s-t) = cos(s)*cos(t) + sin(s)*sin(t)

cos(s-t)= -4/5 * (-[tex]\sqrt{21}/[/tex]5) + (-3/5)*(-2/5)

cos(s-t)= 4[tex]*\sqrt{21}[/tex]/25 + 6/25

cos(s-t)= 0.97321

Answer:

$459

Step-by-step explanation:

Given the following question:

32% of 675

To find the answer to this question we need to use the formula to calculate 32% of 675. Then we subtract that answer from our original price which will then give us our answer.

[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{32\times 675}{100}[/tex]
[tex]32\times675=21600[/tex]
[tex]21600\div100=216[/tex]
[tex]=216[/tex]

Subtract from the original price:
[tex]675[/tex]
[tex]675-216=459[/tex]
[tex]=459[/tex]

The television after a 32% discount will cost "$459."

Answer:

The mean is 6.2.

Step-by-step explanation:

The "mean" is the same thing as the "average". Essentially, the question is asking for the average of the numbers.

So:

Add up all of the terms. [6 + 11 + 5 + 2 + 7] = 31

You find the average by dividing the sum of the terms (31) by the number of terms (5).

31/5 = 6.2

The mean is 6.2.

Answer:

m∠C = 98°

Step 1: Derive an Equation

To solve this problem, we will use what is called the Exterior Angle Theorem. This states that in a triangle, the measure of an exterior angle is equal to the sum of the measures of its 2 corresponding remote interior angles.

In this case, the exterior angle is ∠T (the obtuse one) and the remote interior angles are ∠C and ∠Y. Therefore, m∠T = m∠C + m∠Y.

Substituting the given measures into the equation, we get:

[tex]3x+2+x=130[/tex]

Step 2: Solve the Equation

[tex]3x+2+x=130[/tex]

[tex]4x+2=130[/tex] (Combine like terms)

[tex]4x=128[/tex] (Subtract 2 from both sides to isolate [tex]x[/tex])

[tex]x=32[/tex] (Divide both sides by 4 to get rid of [tex]x[/tex]'s coefficient)

Step 3: Answer the Question

We now know what [tex]x[/tex] is. Therefore, m∠C = [tex]3*32+2=\bf 98 \textdegree[/tex].

To learn more about the Exterior Angle Theorem, check out the following questions:

The equation to describe this situation is that Bobby's cat and dog were 6 miles apart after 30 minutes is 0.5x = 6

Since Bobby's cat runs at x mph, its speed is x mph.

Also, Bobby's dog runs twice as fast as his cat. So, his dog's speed is v = 2x.

Since they both move a distance in t = 30 min = 30 min × 1 h/60 min = 0.5 h.

Bobby' cat's distance in 30 mins is d = x × 0.5 h

= 0.5x miles

Also, Bobby's dog covers a distance in 30 min, D = v × 0.5 h

= 2x × 0.5 h

= x miles

Since Bobbys cat and dog were 6 miles apart after 30 min, we have that

D - d = 6

x - 0.5x = 6

0.5x = 6

So, the equation to describe this situation  that Bobby's cat and dog were 6 miles apart after 30 minutes is 0.5x = 6

Answer:

The converse of the base angles theorem is always true. The base angles theorem states that if two sides of a triangle are congruent the angles opposite them are also congruent. The converse of this statement is that if two angles in a triangle are congruent, then the sides opposite them will also be congruent

Step-by-step explanation:

Answer:

x=16

Step-by-step explanation:

so since a right angle is shown the it's telling that it's an isosceles triangle so you do 22-6=16

answer=16

The equation is written as x + 6 = 22. Then the value of the variable 'x' will be 16.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

From the figure, line AB is divided into two equal parts. Then the triangles will be congruent with each other by SAS postulates.

Then the side length (x + 6) is equal to the side length (22). Then the equation is given as,

x + 6 = 22

Simplify the equation, then we have

x + 6 = 22

x = 22 - 6

x = 16

The equation is written as x + 6 = 22. Then the value of the variable 'x' will be 16.
