Answer:

$45

Step-by-step explanation:

The watch was sold on sale of 40%. This means that the price of the watch on sale is 60% of the original price. (100%-40%=60%)

So, you find the 60% of the original price, $75.

75*0.6=45

Answer:

The answer is that the measure of ∠α is ≈ 20° when rounded to the nearest °

Step-by-step explanation:

To find the measure of ∠α you need to use the reciprocal of the formula for the law of sine which says that a/Sinα = b/Sinβ = c/Sin C. The reciprocal of this gives the new equation that states Sinα/a = Sinβ/b = Sin C/c, and this will help you to find the measure of the missing angle in °'s.

In the triangle line segment BC = 5units is opposite to point A & ∠α. Line segment AC = 7units  is opposite of point and ∠β which is = 28°. And finally, the hypotenuse length and the values of point C & ∠C are unknown, so they aren't important to solving the problem. Knowing all this you can plug in all the known values into the new formula, and start working on figuring things out.

To find the measure ∠α, you first write down everything, putting things into their proper places, so since you're solving for sinα you want the equation to look like this:

sinα/5 = sin28°/7

Then for the second step, you want to isolate the sinα. (To get it by itself × both left and righthand sides by 5 to begin simplifying).

This leaves you with :

sinα = sin28°÷7 · (5)    [And allows you to now solve for the right side of the equation, bringing us to our third step which is to once again simplify. So what you want to do is whip out your calculator and set it to degree mode, so you can find the of sin28° which is = 0.46947156278. Then ÷ that by 7, which will get you a number = 0.06706736611. Finally, take 0.06706736611 × 5,  and you will get the value = 0.33533683056, as your final answer in the third step]

Your equation should now look something like this :

sinα = 0.06706736611 × 5 or 0.33533683056

Moving onto the fourth step, you need to use the inverse of the trig function of sin to get your absolute value. (remember the inverse of sine or acrsin = sin^-1) Here you will need to multiply sin^-1 by 0.33533683056.

And also by now, you'll want to stop writing the equation as sinα = sin^-1 ×

0.33533683056, otherwise you won't get an answer, instead, you'll need to write:

α = sin^-1 × 0.33533683056

So once you do that for the fifth and final step, you'll need to simplify the equation on the righthand side one last time, and you should get the answer of α = 19.5930217327°. Which when rounded to the nearest ° is ≈ 20°.

Answer:

  translated (x, y) → (x - 2, y + 2) and rotated 90° counterclockwise about the origin

Step-by-step explanation:

The image point is in the 3rd quadrant, and the pre-image point is in the first quadrant. This means there has been any of ...

The only answer choice involving the appropriate rotation is ...

  translated (x, y) → (x - 2, y + 2) and rotated 90° counterclockwise about the origin

__

Checking this, we have

  (x, y) ⇒ (x -2, y +2) . . . . translation left 2, up 2

  (x -2, y +2) ⇒ (-y -2, x -2) . . . . followed by 90° CCW rotation

  J(9, 1) ⇒ J'(-3, 7) . . . . . consistent with the given image point

Answer:

Step-by-step explanation: C. 2x+3=1/2(4x+2)+2 hopes this helps:)

The equations that are identities are option B x – 4(x + 1) = –3(x + 1) + 1 and option C 2x + 3 = 1/2(4x + 2) + 2.

To check which equation is an identity, we need to simplify each equation and see if it is true for all values of x.

A. 3(x – 1) = x + 2(x + 1) + 1

Expanding the right side:
3(x – 1) = x + 2x + 2 + 1
3x – 3 = 3x + 3-3 = 3

This is a contradiction and cannot be true for any value of x. Therefore, option A is not an identity.

B. x – 4(x + 1) = –3(x + 1) + 1
Expanding both sides:
x – 4x – 4 = –3x – 3 + 1
-3x – 3 = -3x – 3

This equation simplifies to -3x - 3 = -3x - 3, which is true for all values of x. Therefore, option B is an identity.

Similarly,

Option C is an identity.

Option D is not an identity.

Answer:

  34°

Step-by-step explanation:

∠FZE and ∠BZC are vertical angles, so are congruent. The angle sum theorem tells us ...

  ∠BZC +∠CZD = ∠BZD

  (2x+5) +x = 107

  3x = 102

  x = 34

The measure of ∠CZD is 34°.

Step-by-step explanation:

Answer:

The cost of each kg of almonds is $1.75

The cost of each kg of jelly beans is $2.5

Step-by-step explanation:

We will use the system of linear equations to solve the question

Assume that the cost of 1 kg of almonds is $x, and the cost of 1 kg of jelly beans is $y

∵ For 2 kilograms of almonds and 3 kilograms of jelly beans,

   the total cost is $11

→ Multiply 2 by x and 3 by y, then equate their sum by 11

∴ 2x + 3y = 11 ⇒ (1)

∵ For 6 kilograms of almonds and 5 kilograms of jelly beans, the

   total cost is $23

→ Multiply 6 by x and 5 by y, then equate their sum by 23

∴ 6x + 5y = 23 ⇒ (2)

Now we need to solve this system of equations to find the values of x and y

→ Multiply equation (1) by -3 to make the coefficient of x in it equals

  the coefficient of x in equation (2) in values and differences in signs

∵ -3(2x) + -3(3y) = -3(11)

∴ -6x + -9y = -33 ⇒ (3)

→ Add equations (2) and (3) to eliminate x

∵ (6x + - 6x) + (5y - 9y) = (23 + -33)

∴ -4y = -10

→ Divide both side by -4 to find the value of y

∵  [tex]\frac{-4y}{-4}=\frac{-10}{-4}[/tex]

∴ y = 2.5

→ Substitute the value of y in equation (1) to find x

∵ 2x + 3(2.5) = 11

∴ 2x + 7.5 = 11

→ Subtract 7.5 from both sides

∵ 2x + 7.5 - 7.5 = 11 - 7.5

∴ 2x = 3.5

→ Divide both sides by 2 to find the value of x

∵ [tex]\frac{2x}{2}=\frac{3.5}{2}[/tex]

∴ x = 1.75

∵ x represents the cost of 1 kg of almonds

∴ The cost of each kg of almonds is $1.75

∵ y represents the cost of 1 kg of jelly beans

∴ The cost of each kg of jelly beans is $2.5

Complete Question

Answer:

The correct option are option 2 and option 4

Step-by-step explanation:

From the question we are told that

   The sample size is  n = 12  

    The test statistics is  [tex]t \approx 1.434[/tex]

    The level of significance is  [tex]\alpha = 0.05[/tex]

    The  rejection region is    t>1.796

   The null hypothesis [tex]H_o: \mu_d=0[/tex]

    The alternative hypothesis is  [tex]H_a : \mu_d >0[/tex]

 From the given values we see that t <  1.796(i.e   1.434 < 1.796 ) which implies that t is not within the rejection region

  Hence we fail to reject the null hypothesis

The conclusion is that there is insufficient evidence to suggest that that the husbands are significantly older than the wife.
