Step-by-step explanation:

Answer:

$2471.53

Step-by-step explanation:

Use the compound amount formula:

A = P(1 + r/n)^(nt), where n is the number of compoundings per year

Here,

A = ($2,400)(1 + 0.019/12)^(12·3), or

      ($2,400)(1.0015)^36

    =  ($2,400)(1.026) =

     =  $2471.53

Answer: The answer is A

Answer:

60

Step-by-step explanation:

if x = 4, plug that value into the equation

y = 2*4 + 52

y = 8 + 52

y = 60

Answer:

d. $681.15

Step-by-step explanation:

Bedroom 1:

Width = 10 ft

Length = 8.5 ft

Area of bedroom 1 = length × width

= 10 ft × 8.5 ft

= 85 ft²

Bedroom 2:

Width = 11.75 ft

Length = 13.25 ft

Area of bedroom 2 = length × width

= 11.75 ft × 13.25 ft

= 155.6875 ft²

Total carpet in the two bedrooms = 85 ft² + 155.6875 ft²

= 240.6875 ft²

If the

carpet he wants to buy is $2.83 per square foot, then how much will it cost for both rooms?

Total cost for both rooms = Total carpet in the two bedrooms × cost per square foot

= 240.6875 ft² × $2.83

= $681.145625

Approximately $681.15

Answer:

26 for the first and 18 for the second.

Step-by-step explanation: 44-8=36. 36÷ 2=18. 18+8=26. So, you get 26 and 18 hours.

Answer:

A=3, B=4, C=-5

Step-by-step explanation:

So A represents the amplitude, which is the distance between the midline (C), the middle of the graph, and the maximum (or minimum). B is the distance of the period of the graph. In this case, we see that the midline is C=-5 because that is the halfway point of the sine function. We also see that the period distance is B=5-1=4, so our period would be 2π/4 or π/2. Our amplitude would be A=3 because |a|=|-5-(-2)|=|-5+2|=|-3|=3. Observe the graph to see this visually.

Answer: [tex]y=\dfrac{3}{4}x[/tex]

Step-by-step explanation:

Given

3 cups of milk are required for 4 cups of flour

Suppose there are x cups of milk and y cups of flour

So, according to the question

[tex]\Rightarrow 3x=4y\\\\\Rightarrow y=\dfrac{3}{4}x[/tex]

The above equation represents the linear equation.

Answer:

C. 3.5 mi

Step-by-step explanation:

Reference angle = angle of elevation

Angle of elevation = angle of depression = 6° (alternate angle theorem)

Hypotenuse = x

Opposite = 1905 ft

Apply trigonometric function SOH:

Sin 6° = Opp/Hyp

Sin 6° = 1905/x

x * Sin 6° = 1905

x = 1905/Sin 6°

x = 18,224.7 ft

Convert form feet to miles

1 mi = 5,280 ft

Therefore,

18,224.7 = 18,224.7/5,280

= 3.45164773 mi

≈ 3.5 mi (nearest mile)

Answer: $27.89

Step-by-step explanation:

Since the price decreases every week by 10%, its is basically being marked down to 90% of its original value. We can construct an equation for this, where we have our original value, multiply by a modifier, and raise the modifier to a power equal to the number of weeks it is on sale. Since the original price was $80, that will be 80. Since it is 10% off, we will multiply by 0.9, and since its ten weeks, we will raise the 0.9 to the power of 10.

Thus, 80×0.9^10 = 27.89

Answer:

14.6

Step-by-step explanation:

We solve using the Trigonometric function Cosine

cos θ = Adjacent/Hypotenuse

θ = 40°

Hypotenuse = 19

Adjacent = x

Therefore,

cos 40 = x/19

Cross Multiply

x = cos 40 × 19

x = 14.554844419

Approximately to the nearest tenth,

x = 14.6

Answer: [tex]39\ \text{Ounces}[/tex]

Step-by-step explanation:

Given

The amount of cashews is [tex]1\frac{1}{4}\ \text{Pounds}[/tex]

Amount of almonds [tex]7\ \text{ounces}[/tex]

The amount of pecans is [tex]\frac{3}{4}\ \text{Pounds}[/tex]

We know, [tex]1\ \text{Pound}=16\ \text{Ounces}[/tex]

Converting pounds to ounces and adding them

[tex]\Rightarrow 1\dfrac{1}{4}\times 16+7+\dfrac{3}{4}\times 16\\\\\Rightarrow \dfrac{5}{4}\times 16+7+3\times 4\\\\\Rightarrow 20+7+12=39\ \text{ounces}\ or\ \dfrac{39}{16}\ \text{Pounds}[/tex]

Thus, the nuts weigh [tex]39\ \text{Ounces}[/tex]

Given:

A regular hexagon with side 11.5 units and apothem 10 units.

To find:

The area round to the nearest tenth.

Solution:

Area of a regular polygon is:

[tex]A=\dfrac{1}{2}Pa[/tex]           ...(i)

Where, P is the perimeter and a is the apothem.

The given figure is a regular hexagon with six sides. So, the perimeter of the given figure is the product of number of sides and the side length.

[tex]P=6\times 11.5[/tex]

[tex]P=69[/tex]

Putting [tex]P=69,a=10[/tex], we get

[tex]A=\dfrac{1}{2}(69)(10)[/tex]

[tex]A=(69)(5)[/tex]

[tex]A=345 [/tex]

Therefore, the area of the regular polygon is 345.0 square units.

Given :

Magnitude of vector is 30 units.

Direction of vector from x-axis is 116°.

To Find :

The component form of the vector.

Solution :

We know, vector in component form is given by :

[tex]\vec{v} = (Acos\ \theta) \hat{i} + (Asin\ \theta)\hat{j}[/tex]

Putting given values,

[tex]\vec{v} = (30\times cos\ 116^o) \hat{i} + (30\times sin\ 116^o)\hat{j}\\\\\vec{v} = -13.15 \hat{i} + 0.90 \hat{j}[/tex]

Hence, this is the required solution.

Answer:

x = 25

Step-by-step explanation:

Using the formula a²+b²=c², you can easily find out the hypotenuse of the triangle (which is the long side of it, and is the x in this problem.)

If we substitute the side lengths for the question in a²+b²=c², you'll get

20²+15²=x²

Simplifying the numbers and squaring them, you get

400+225=625²

Since you want the value of the x side, you'll need to root 625.

√625=25

Therefore, x = 25

Answer:

x = 25

Step-by-step explanation:

To find the side lengths of a right triangle, we can use the Pythagorean Theorem, a² + b² = c². a and b are the legs, and c is the hypotenuse, the longest side. In this figure, x is the hypotenuse, c.

Plug in our values for a and b and solve for x.

[tex]a^2+b^2=c^2[/tex]

[tex]20^2+15^2=c^2[/tex]

[tex]400+225=c^2[/tex]

[tex]625=c^2[/tex]

[tex]\sqrt{625}[/tex] = [tex]\sqrt{c^2}[/tex]

[tex]25=c[/tex]

c, or x is equal to 25. The missing sidelength is 25 units.

Good luck ^^

Answer:

512 in^3

Step-by-step explanation:

It would be length x height x width = AREA

8 x 8 x 8= 512 and since its 3d it will be 512^3

Answer:

To find the hypotenuse, you would use the formula a^2 + B^2 = C^2

That is the formula for the pythagorean theorem.

I suggest you first plot it on a graph, then could the units on the sides that make up the legs.

When you plot it, the legs are both 1 unit.

so it would be, following the formula:

1^2 + 1^2 = c^2

1 x 1 + 1 x 1 = c^2

2 = c^2

Then you square root:

√2 = √c^2

1.41421356 = c

1.41421356 rounded to the nearest tenth is 1.4.

So the length of (5,1), (4,0) is ≈1.4
