Answer:

∠F = 50°

Step-by-step explanation:

The sum of all three angles in a triangle = 180°

∠F = 180° - 30° - 100° = 50°

Answer: 180 miles

Step-by-step explanation:

From the question, we should note that the distance taken will be calculated by using the formula which will be:

Distance = Rate × Time

where,

Rate = 60 miles per hour

Time = 3 hours

Distance = 60 × 3

Distance = 180 miles

Therefore, the distance travelled is 180 miles.

Answer:

  c.  x = 7-t; y = -1/(t -7)

Step-by-step explanation:

To find the parametric equation for x, use the equation for t and solve for x.

  t = 7-x

  x = 7 -t . . . . . . add x-t to both sides

__

To find the parametric equation for y, substitute the equation for x.

  y = 1/x

  y = 1/(7-t)

To make this match the available choices, we need to multiply numerator and denominator by -1.

  y = -1/(t -7)

The parametric equations are ...

  x = 7 -t; y = -1/(t -7) . . . . . . matches choice C

Answer: it is C

Answer:

927.84

Step-by-step explanation:

The total cost of the antique clock that Janice bought is $927.82 approximately.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, we have:

Total cost = (discounted price of clock)'s price + sales tax of discounted price.

Let d = discounted price of the clock

Then, we have:

[tex]d = $967 - \text{5\% discount on 967} \\\\d = 967 - \dfrac{967}{100} \times 5 = \$918.65[/tex]

1% sales tax on 'd' will be: [tex]\dfrac{d}{100} \times 1 = \$9.1865 \approx \$9.19[/tex]

Thus, we get:

Total cost of the clock ≈ 918.65 + 9.19 = 927.82 (in dollars)

Thus, the total cost of the antique clock that Janice bought is $927.82 approximately.

Answer:

54 unit^2.

Step-by-step explanation:

The area = the sum of the 2 triangles.

Area of a triangle = 1/2 * base * height.

So here:

A = 1/2 * 4 * 12 + 1/2 * 5 * 12

= 24 + 30

= 54

Answer:

Explanation:

the area of the polygon = the area of the triangle ADC + the area of the triangle ABC

the area of a triangle = (height × base)/2

A ADC = (DE×AC)/2

A ADC = (4×12)/2

A ADC = 48/2

A ADC = 24 u²

A ABC = (BF×AC)/2

A ABC = (5×12)/2

A ABC = 60/2

A ABC = 30 u²

ABCD = A ADC + A ABC

ABCD = 24 + 30

ABCD = 54 u²

Answer:

AB = 2×2=4, 3×3=9, 4×4=16, 5×5=25

Answer:

Yes because after solving the equation, x does indeed equal 14.

Step-by-step explanation:

-5 + 2x = 23

2x = 23 + 5

2x = 28

x = 14

Answer:

-5 + 2x= 23 x= 14 (Correct)

Step-by-step explanation:

This is true because the first step you take to sloving this equation is to move the constant to the right. Then calculate. Divide both sides and your answer should equal x=14!

Step-by-step explanation:

Given data

Number of purses= 14+2= 16

Cost of 14 purses= $50

Cost of 2 purses= $38

Let us use the weighted cost method

Mean cost = (14*50+ 2*38)/16

Mean cost = (700+ 76)/16

Mean cost = 776/16

Mean cost =$48.5

Answer:
