Which multiplication expression can be used to check this division problem: 2/5 divided by 4/15 = 3/2

O 2/5 times 4/15
O 3/2 times 4/15
O 3/2 times 15/4
O 5/2 times 15/4

Answers

Answer 1

Answer:

I'm pretty sure it's B

Step-by-step explanation:

Answer 2

Answer:

3/2 times 4/15

Step-by-step explanation:

In division, the quotient times the divisor equals the dividend. This multiplication can be used to check if the math was correct.

Here's an example:

6 / 3 = 2

6 is the dividend, 3 is the divisor, and 2 is the quotient.

2 times 3 is 6, which proves that the quotient times the divisor is the dividend , and it also means that the quotient was correct.

(This example was used because the numbers are nice and easy, so they are good examples for this kind of thing)

At cultutral arts day each session lasts 4/5 hours. The principal has set aside 3 hours for the sessions. Determine the number of sessions that can be sheduled for each student

Answers

Answer: 3.75

Step-by-step explanation:

The following can be gotten from the question:

Time taken for each session = 4/5 hours

Total time set aside by principal = 3 hours

The number of sessions that can be sheduled for each student will be:

= Total time set aside by principal / time taken for each session

= 3 hours / 4/5 hours

= 3 × 5/4

= 3.75

3. Priya says, "I know everything about a right triangle with a 30 degree angle and a hypotenuse with length 1 cm. Here look." The other angle is 60 degrees. The leg adjacent to the 30 degree angle 0.866 cm long. The side opposite the 30 degree angle is 0.5 cm long. Han asks, "What would happen if a right triangle with a 30 degree angle has a hypotenuse that is 2 cm instead?" Help them find the missing angles and side lengths in the new triangle. Explain or show your reasoning.

Answers

Answer:

1) The measure of the third angle is 60°

2) The length of the opposite side to the angle 30° is 1 cm

3) The length of the opposite side to the third angle 60° is approximately 1.732 cm

Step-by-step explanation:

1) The given parameters are;

The known angle of a right triangle = 30°

The length of the hypotenuse = 2 cm

Given that the triangle = A right triangle, with one of the interior angles = 90°, we have;

The measure of the third angle = 180° - 90° - 30° = 60°

The measure of the third angle = 60°

2) We have that sin(30°) = 0.5 = (The length of the opposite side to the angle 30°)/(The length of the hypotenuse side)

0.5 = (The length of the opposite side to the angle 30°)/(2 cm)

∴ The length of the opposite side to the angle 30° = 2 cm × 0.5 = 1 cm

The length of the opposite side to the angle 30° = 1 cm

3) Similarly, the length of the opposite side to the third angle 60° = sin(60°) × (The length of the hypotenuse side)

∴ The length of the opposite side to the third angle 60° = (√3)/2 × 2 cm = √3 cm

The length of the opposite side to the third angle 60°  = √3 cm ≈ 1.732 cm

Use the elimination method to solve the system of equations. Choose the correct ordered pair

-x+5y=-4

4x+3y=16

Will give brainiest.

Answers

Answer:

x = 4 and y = 0

Step-by-step explanation:

Using the elimination method:

4(-x + 5y=-4) --> -4x + 20y = -16.

Now we add -4x + 20y = 016 and 4x + 3y = 16. This gives us 23y = 0 or just y =0.

Now we can find x by plugging in y.

-4x + 0 = -16.

Divide by -4 on both sides -> x = 4.

If you want to double check you can plug your values into -4x + 20y = -16.

-4(4) +20(0) = -16.

Anyone plz help me ty

Answers

Answer:

it would be an acute angle because it is less than 90

Answer:

It would be a right triangle

Step-by-step explanation:

A triangle must always have 3 angles that add up to 180°.

So if two angles are 45°, then the last angle has to add along with the 45° angles to equal 180°.

If you multiply 45 × 2 (since there are two angles that are 45°), you get 90, which is half of 180.

Also a 90° angle is a right angle, which would help you out with remembering.

find the value of x ​

Answers

Answer:

x = 12

Step-by-step explanation:

In a pair of intersecting lines the vertically opposite angles are equal.

[tex] \longrightarrow [/tex] (6x + 7)° = (8x - 17)°

[tex] \longrightarrow [/tex] 6x + 7 = 8x - 17

Subtract 8x + 7 from both sides:

[tex] \longrightarrow [/tex] 6x + 7 - (8x + 7) = 8x - 17 - (8x + 7)

[tex] \longrightarrow [/tex] (6x - 8x) + (7 - 7) = (8x - 8x) + (-17 - 7)

6x - 8x = -2x:

[tex] \longrightarrow [/tex] -2x + (7 - 7) = (8x - 8x) + (-17 - 7)

7 - 7 = 0:

[tex] \longrightarrow [/tex] -2x = (8x - 8x) + (-17 - 7)

8x - 8x = 0:

[tex] \longrightarrow [/tex] -2x = -17 - 7

-17 - 7 = -24:

[tex] \longrightarrow [/tex] -2x = -24

Divide both sides by -2:

[tex] \longrightarrow [/tex] [tex] \sf \dfrac{-2x}{-2} = \dfrac{-24}{-2} [/tex]

[tex] \sf \dfrac{-2}{-2} = 1 [/tex]

[tex] \longrightarrow [/tex] [tex] \sf x = \dfrac{-24}{-2} [/tex]

[tex] \sf \dfrac{-24}{-2} = 12 [/tex]
