Answer:

70

Step-by-step explanation:

An angle on the circle is half of the intercepted arc. Since the circle is 360, you can subtract 220 from 360 and find the intercepted arc which is 140. Divide that by 2 and you get 70.

Answer: 119°

Step-by-step explanation:

A circle equals 360° degress. If you subtract the two angles shown in the picture you'll get 238°.

Now vertical angles are congurent thus if we divide 238 into 2 we get 119°.

Answer:

$348.29

Step-by-step explanation:

The payment is calculated by multiplying the rate per hundred times the number of hundreds. The latter is found by dividing the loan amount by $100.

$2.41 × $14,452/$100 ≈ $348.29

Answer:$299.16

Step-by-step explanation:

Financed amount = $14452

APR  = 8.9%

Period / time = 5 years

monthly payment = $100 for every $2.07

To calculate the monthly payment of a financed amount we multiply the financed amount by the ratio of the given amount paid per $100

The monthly payment would be =  14452 * 2.07/100 = 14452 * 0.0207

= $299.16 approximately

therefore the monthly payment of a financed amount of $14452 is equal to $299.16

#4

Step-by-step explanation:

Graph #4 is the correct one.  Multiplying x by 1/4 widens the original graph by a factor of 4.  That "-4" shifts the graph 4 units to the right.

Step-by-step answer:

A line with slope (or gradient) m, passing through a point (x0,y0) can be represented by the equation:

(y-y0) = m(x-x0)  ......................(1)

Here,

(x0,y0) = (1,7), and

slope/gradient = -2

Substitute values into (1) above gives

(y-7)=2(x-1)

Expand and simplify

y-7 = 2x-2

y =2x -2 + 7

y=2x+5

Answer:

7/15

Step-by-step explanation:

odd numbers are those that do not have divides ie1,2,3,5,7,11,13

The probability of randomly selecting an odd number from the numbers 1-15 is 8/15.

Probability is used to know the odds that an event would happen.  The probability the event occurs is 1 and the probability that the event does not occur is 0.

Probability that a randomly selected number would be odd = number of odd numbers / total numbers

Odd numbers between 1 and 15 = 1 , 3, 5, 7, 9, 11, 13, 15

Probability that a randomly selected number would be odd = 8/15

Part A:

We are given that E is 3 more than D. This means that to get the value of E, we will simply add 3 to the value of D

Therefore:

E = D + 3

Part B:

We are given that F is 5 less than D. This means that to get the value of F, we will simply subtract 5 from the value of D

Therefore:

F = D - 5

Part C:

To get the value of E-F, we will simply subtract the equation we obtained from part B from the equation we obtained from part A

Therefore:

E - F = (D+3) - (D-5)

E - F = D + 3 - D + 5

E - F = 8

Hope this helps :)

The expression for 'e' in terms of 'd' is e = d + 3. The expression for 'f' in terms of 'd' is f = d - 5. The difference between 'E' and 'F' is 8.

A) e = d + 3
To express 'e' in terms of 'd,' we can simply say that 'e' is equal to 'd' plus 3. This is because the question states that 'E is 3 more than D.'

B) f = d - 5
To express 'f' in terms of 'd,' we can say that 'f' is equal to 'd' minus 5. The question states that 'F is 5 less than D.'

C) E - F = (d + 3) - (d - 5) = d + 3 - d + 5 = 8
To find the difference between 'E' and 'F,' we can substitute the expressions we found for 'e' and 'f' into the equation. Simplifying the expression further, we have 'E - F = (d + 3) - (d - 5) = d + 3 - d + 5 = 8.'

Step-by-step explanation:

⇒ sin (49°) = cos (90° - 49°) = cos (41°)

Sinus is a periodic trigonometric function, defined in the context of a right triangle as the ratio of the opposite leg to the hypotenuse.

Cosinus is a periodic trigonometric function, defined in the context of a right triangle as the ratio of the adjacent leg to the hypotenuse.

Final answer:

To find the value of x where sin49° equals cosx, we utilize the identity sin(90° - x) = cos x, which yields the answer x equals 41°.

Explanation:

To find the value of x where sin49° = cosx, we use the trigonometric identity sin(90° - x) = cos x. Since sin49° is given, we can set up our equation as:

sin(90° - x) = sin49°.

This reveals that 90° - x = 49°

Solving for x, we get:

x = 90° - 49°

x = 41°

Therefore, the value of x is 41°.

The difference in investment between the largest and the smallest is 50,000

Final answer:

To find out the investments of three friends in a ratio of 2:5:7, one part is calculated as $10,000. The smallest investor contributes $20,000 and the largest investor contributes $70,000. Hence, the difference in their investments is $50,000.

Explanation:

The question is asking to determine the individual investments of three friends in a food truck business based on their total contributions amounting to $140,000 and the ratio of their investments being 2:5:7. First, we find the total number of parts in the ratio (2+5+7=14 parts). To find the value of one part, we divide the total investment by the number of parts ($140,000 \/ 14 = $10,000 per part).

Now, we can calculate each friend's investment:

The difference in investment between the smallest and the largest investor is $70,000 - $20,000 = $50,000.

Step-by-step explanation:

we know that

The volume of a sphere is equal to

[tex]V=\frac{4}{3} \pi r^{3}[/tex]

we have

[tex]r=6\ ft[/tex]

substitute

[tex]V=\frac{4}{3} \pi (6)^{3}[/tex]

[tex]V=288\pi\ ft^{3}[/tex]

The volume of the sphere with a radius of 6 ft is 904.78 ft³.

The volume of a sphere can be calculated using the formula: V = (4/3)πR³. Given a radius of 6 ft, we can substitute this value into the formula to find the volume:

V = (4/3)π(6 ft)³

V = (4/3)π(216 ft³)

Answer:

The trains will meet after 2.6 hours.

Step-by-step explanation:

Add up the distances traveled by the two trains:

distance1 = (100 mph)(t hours)

distance2 = (90 mph)(t hours)

Sum of distance1 and distance2 = 494 miles = (190 mph)(t hours)

Solving for t, we get   t = 494 miles / 190 mph  = 2.6 hours

The trains will meet after 2.6 hours.

It will take 2.60 hours for the two trains to meet.

To find out how long it will take for the two trains to meet, we can use the formula: time = distance / speed.

Since the trains are traveling towards each other, we can add their speeds together to get the effective speed: 100 mph + 90 mph = 190 mph.

Now we can plug in the values: time = 494 miles / 190 mph = 2.60 hours.
