Answers

Answer:

-12=-8 -4

-4= -9 +5

4=9+ (-5)

12= 8-(-4)

Step-by-step explanation:

We can drag the numbers to the boxes on the right to match the expressions:

-12 → -8 - 4

-4 → -9 + 5

4 → 9 + (-5)

12 → 8 - (-4)

To match each expression on the left with its numeric equivalent, we can simply evaluate the expressions:

Expressions play a crucial role in human interaction, conveying emotions, intentions, and information without the need for extensive verbal communication. They enrich our conversations and help create deeper connections with others.

-9 + 5 = -4

9 + (-5) = 4

8 - (-4) = 12

-8 - 4 = -12

Now, we can drag the numbers to the boxes on the right to match the expressions:

-12 → -8 - 4

-4 → -9 + 5

4 → 9 + (-5)

12 → 8 - (-4)

Lines a and b are parallel. What is the measure of angle s?






S= Enter your answer in the box.​

Answers

Answer:

Step-by-step explanation:

t = 158                         Corresponding angles

t + s = 180                   They are supplementary angles

158 + s = 180               Subtract 158 from both sides

s = 180 - 158

s = 22

As a note, all angles in this situation are either 158 or 22.

Answer:

  2/15

Step-by-step explanation:

The given expression for θ can be rewritten to ...

  5sin(θ + arctan(-3/4)) = 0

This will have solutions ...

  θ +arctan(-3/4) = nπ

  θ = nπ - arctan(-3/4) = nπ + arctan(3/4)

__

The corresponding values of sine and cosine will be ...

  sin(arctan(3/4)) = 3/5

  cos(arctan(3/4) = 4/5

or both values may be negative. Either sign will give the same result in the expression we're to find.

  (2sin(θ) -cos(θ))/(sin(θ) +3cos(θ)) = (2(3/5) -(4/5))/(3/5 +3(4/5))

  = ((6 -4)/5)/((3+12)/5) = 2/15

and of Tank is nilled with water. The ratio of the volume of water in
Tank A to that in Tank Bis 5. 2. How much more water is needed to up
Tarik ?​

Answers

Answer:

72L

Step-by-step explanation:

I'm assuming Tank A and Tank B have the same volume. The question has many typos and is a bit hard to understand

Tank A Volume

V = l × w × h

= 80 × 30 × 50

= 120,000cm²

Tank A Capacity = 120,000ml

=120L

The Question states that Tank A is filled to capacity which means Tank A currently holds 120L of water

Tank A:Tank B = 5:2 = 120:x

120 ÷ 5 = 24L

24 × 7 = 168

168 × [tex]\frac{2}{7}[/tex] = 48

This means Tank B currently holds 48L of water

120 - 48 = 72L

∴72 more litres of water is needed to fill Tank B

Step-by-step explanation:

Since the radius of the silo is 10 meters, then the total length of the silo is 20 meters. So now we multiply 75 by 20

75 x 20 = 1500

So the value of the rice in the silo is $1500

The volume of this triangular prism is 20[tex]cm^{3}[/tex]

Step-by-step explanation:

Just like it is shown in the picture we can use the formula for the volume of a triangular prism.

[tex]V = \frac{1}{2}bhl[/tex]

In our case b = 5cm, h = 2 cm, l = 4cm. Now we just plug in the values and get...

[tex]V = \frac{1}{2}bhl\\\\[/tex]

[tex]V = \frac{1}{2}(5)(2)(4)[/tex]

[tex]V = 20cm^{3}[/tex]

Therefore the volume of the triangular prism is 20[tex]cm^{3}[/tex].

Answers

Answer:

82 and 98.

Step-by-step explanation:

set up 2 equations

x+y=180

2x+16=180

you start by solving the second equation to find one of the angles.

180-16= 164

2x=164

164÷2= 82

x=82

since you've solved that equation, add in the missing variable to solve for the next one

82+y=180
