Really struggling with this one. Can someone help please?​

Answer:

The correct answer is $5,29

Step-by-step explanation:

The unit price helps us determine the price for a single unit of something that has been purchased in a group.

In this case we have a package of 5 pairs of insulated gloves, which includes 5 pairs and costs 29.45.

We want to know what the unit price is, that is, how much does a single pair of gloves cost.

To determine this we simply divide the total price by the number of gloves:

29.45 / 5 = 5.29

In this way we can confirm that the unit price of a pair of insulated gloves is $ 5.29.

Answer:

Each pair of gloves is $5.29

Answer: 3/16

Step-by-step explanation:

- you divide 3/16 which gets you to the answer of 0.1875

A fraction is a way to describe a part of a whole. The size of the bolt that will best fit in the wrench is 3/16 inches.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Jaylon has a wrench labeled 0.1875 inch and bolts labeled in fractions of an inch.

Now, the size of the bolt that will best fit in the wrench will be the bolt of size same as the wrench. Therefore, if we rewrite the size of the wrench it will be,

Size of the bolt = Size of the wrench

                         = 0.1875 inches

                         = 1875/10000 inches

Divide both the numerator and the denominator by 625

                         = 3/16 inches

Hence, the size of the bolt that will best fit in the wrench is 3/16 inches.

Answer:

  29.2%

Step-by-step explanation:

The fraction of students with black hair is 7/24. To convert that to a percentage, multiply by 100%.

 7/24×100% = 29.1666(repeating)% ≈ 29.2%

Step-by-step explanation:

8 cos 80° cos 140° cos 160°

4 (2 cos 80° cos 140°) cos 160°

4 cos 160° (2 cos 80° cos 140°)

Use product to sum formula.

4 cos 160° (cos 60° + cos 220°)

4 cos 160° (½ + cos 220°)

2 cos 160° + 4 cos 220° cos 160°

2 cos 160° + 2 (2 cos 220° cos 160°)

Use product to sum formula again.

2 cos 160° + 2 (cos 60° + cos 380°)

2 cos 160° + 2 (½ + cos 380°)

2 cos 160° + 1 + 2 cos 380°

2 cos 160° + 1 + 2 cos 20°

Use shift identity cos(180 − θ) = -cos θ.

-2 cos 20° + 1 + 2 cos 20°

Our question that we have at hand here is 8(cos 80°)(cos 140°)(cos 160°). We need to convert that into 'decimal form' to prove that it equals 1. However decimal form doesn't generally give us a decimal, in this case.

Let's start by using the identity cos(s)cos(t) = cos(s + t) + cos(s - t) / 2. In this case we are looking particularly at the expression (cos 80°)(cos 140°), where s = 80, and t = 140.

[tex]\cos \left(80^{\circ \:}\right)\cos \left(140^{\circ \:}\right)=\frac{\cos \left(80^{\circ \:}+140^{\circ \:}\right)+\cos \left(80^{\circ \:}-140^{\circ \:}\right)}{2}[/tex]

[tex]=8\cdot \frac{\cos \left(80^{\circ \:}+140^{\circ \:}\right)+\cos \left(80^{\circ \:}-140^{\circ \:}\right)}{2}\cos \left(160^{\circ \:}\right)[/tex]

[tex]= 4\cos \left(160^{\circ \:}\right)\left(\cos \left(220^{\circ \:}\right)+\cos \left(-60^{\circ \:}\right)\right)[/tex]

To further simplify this expression, we know that cos(- 60°) = cos(60°). This may not seem like a very effective step, but we can apply a few trivial identities here. Remember that cos(60°) = 1 / 2,

[tex]4\cos \left(160^{\circ \:}\right)\left(\cos \left(220^{\circ \:}\right)+\frac{1}{2}\right)[/tex]

[tex]= 4(0.25)\\= 1[/tex]

And hence we proved that 8(cos 80°)(cos 140°)(cos 160°) in decimal form, = 1.

QR = 81

Step-by-step explanation:

PR = 145

= PQ + QR

= (8x) + (11x - 7)

8x + 11x - 7 = 145

19x = 145 + 7

19x = 152

x = 8

substitute x=8 into QR:

11(8) - 7 = 81

Answer: Jeffery paid $ 2937 in all.

Step-by-step explanation:

Given: The cost of antique pull = $890

Mark up percentage = 200%

New price = (cost) + (Mark up percentage) x (cost)

[tex]=\$( 890+\dfrac{200}{100}\times890)\\\\=\$( 890+2(890))\\\\=\$2670[/tex]

After a tax of 10% , the amount needs to be paid = New price + 10% of New price

 [tex]=\$(2670+\dfrac{10}{100}\times2670)=\$(2670+267)\\\\=\$2937[/tex]

Hence, Jeffery paid $ 2937 in all.

Answer:

$1.36

Step-by-step explanation:

First, add together the prices of all the clothes:

18.28 + 42.39 + 12.97

= 73.64

Then, subtract this from 75:

75 - 73.64

= 1.36

So, he will have $1.36 left after buying the clothes

The money Marco have left after he buys his clothes is $1.36.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, Marco has $75 to spend on new clothes for a job interview.

Let the money left after he purchase his clothes be x.

Cost of shirt=$18.28, cost of pants=$42.39 and cost of tie =$12.97

Now, x=75-(18.28+42.39+12.97)

x= 75-73.64

x= $1.36

Therefore, the money Marco have left after he buys his clothes is $1.36.

(-9, 10)

Step-by-step explanation:

The location of the midpoint of a line with endpoint at ([tex]x_1,y_1[/tex]) and ([tex]x_2,y_2[/tex]) is given as (x, y). The location of x and y are:

[tex]x = \frac{x_1+x_2}{2},y=\frac{y_1+y_2}{2}[/tex]

Given the endpoint (9,8) and Midpoint (0,9), the location of the other endpoint can be gotten from:

Hey there!

A line parallel to y=-4x+3 would have a slope of -4.

Point slope form: y-2=-4(x+3)

Simplify: y=-4x-10

Let me know if this helps :)

Answer:

A

Step-by-step explanation:

So we want an equation that is parallel to:

[tex]y=-4x+3[/tex]

And passes through:

[tex](-3,2)[/tex]

First, since we want the equation to be parallel to the first, the slope must be -4. This is because parallel lines have the same slope.

Now that we know the slope of our equation is -4, we can use the point-slope form to figure out the rest.

The point-slope form is:

[tex]y-y_1=m(x-x_1)[/tex]

m is -4. Let (-3,2) be x₁ and y₁. Thus:

[tex]y-2=-4(x--3)[/tex]

Simplify:

[tex]y-2=-4(x+3)[/tex]

Distribute:

[tex]y-2=-4x-12[/tex]

Add 2 to both sides:

[tex]y=-4x-10[/tex]

So our answer is A :)

divide each side by 4

-24/4 = 4v/4

First, add 18 to both sides:

-42 (+18) = 4v - 18 (+18)

-42 + 18 = 4v

4v = 18 - 42

4v = -24

Next, divide 4 from both sides:

(4v)/4 = (-24)/4

v = -24/4

v = -6

v = -6 is your answer.

Answer:

I went on a train trip and traveled 250 miles in 2 hours.

What is the train's rate of speed in miles per hour?

Answer: divide the number of miles by the time in hours.

rate of speed = (250 miles)/(2 hours) = 125 miles per hour

w = 57.5 yards

l = 169.5 yards

P = 2w + 2l

466 = 2w + 2l

l = 3w - 3

466 = 2w + 2(3w - 3)

466 = 2w + 6w - 6

466 - 6 = 8w

8w = 460

w = 460 : 8

w = 57.5 yards

l = 3w - 3

= 3×57.5 - 3

= 169.5

l = 169.5 yards

Answer:

179 minutes

Step-by-step explanation:

From the information given, you know that the total cost of the long distance service is equal to 7 plus the result of multiplying 0.7 for the number of minutes:

Total cost=7+0.07x, where x is the amount of minutes.

Now, you can replace the total cost with 19.53 that is the amount Ali was billed and solve for x:

19.53=7+0.07x

19.53-7=0.07x

12.53=0.07x

x=12.53/0.07

x=179

According to this, the answer is that Ali was billed for 179 minutes.
