Step-by-step explanation:

For the problem:

3 1

= ?

Convert any mixed numbers to fractions:

3 1

=  

7

Division of fractions is equivalent to multiplication by the reciprocal of the second fraction:

7

2

÷

1

Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:

7 × 2

2 × 1

=  

14

2

The Greatest Common Factor (GCF) of 14 and 2 is 2. The result can be simplified by dividing both the numerator and denominator by 2.

=  

14 ÷ 2

2 ÷ 2

= 7

The result is:

Answer:

130 degrees

Step-by-step explanation

Angle 6 is 130 degrees because it has a vertical angle relationship with the angle measure of 130 degree

Angle 6 and 2 are equal because of the corresponding angle relationship

OR

The angle measure of 130 degrees have an alternate interior angle relationship with angle 2 which makes them equal

Therefore angle 2 is 130

Answer:

The first one

Step-by-step explanation:

Its just playing with the signs, its not ____ and equal to so the last two arent it (because of the empty circle) and its greater than -1 so its number 1.

Answer:

Graph B

Step-by-step explanation:

Because th inverse fuction is f^-1(x), you basicaly swap the numbers, all x valuese would equal y.

In this exercise we have to identify the treated inverse function and the graph that corresponds to it, so we have that what corresponds to this is:

Graph B corresponds to the given function.

In this way, the inverse function corresponding to:

[tex]f^{-1}(x)[/tex]

Because th inverse fuction is f^-1(x), you basicaly swap the numbers, all x valuese would equal y. So we will have that the graph that correctly corresponds to this function is graph B.

Answer:

- 3 ( 2x+1 ) 20

8x+5

_____________

8x+5×20 -3 ( 2×12.5+1 )

8×=100 -3 ( 25+1 )

100÷8= 12.5 -3 ( 26 )

×= 12.5

-3 ( 26 )

-3×2 + -3×6 = -6+ -18 = -24

-24

Answer:

28.0

Step-by-step explanation:

if rounding to the nearest tenth then the number in the hundredth determines what to do - if the number in hundredths is '5 and above, give it a shove'

meaning in this case the 7 bumps the 9 up by one; but a nine will carry over and bump the number in the ones place up by one

Answer:

28

Step-by-step explanation:

Hi there!

This decimal is a tricky one.

we know we’re rounding to the nearest tenth, so the hundredths place will come in handy.

Since there is a 7 in the hundredths place, we know we’re going to round up, but we have a 9 in the tenths place, so it would become a ‘10’, which is just going into the next whole number, which is 28.

I hope this helped!

Answer:

t>-2

Step-by-step explanation:

So Act like this is an equation and add -3 to both sides:

t>-2

Thats your answer!

The correct choice should be #1

==================================================

Explanation:

Apply the law of cosines to find angle C

c^2 = a^2 + b^2 - 2*a*b*cos(C)

19^2 = 11^2 + 17^2 - 2*11*17*cos(C)

361 = 121 + 289 - 374*cos(C)

361 = 410 - 374*cos(C)

361 - 410 = -374*cos(C)

-49  = -374*cos(C)

-374*cos(C) = -49

cos(C) = (-49)/(-374)

cos(C) = 0.131016042780749  ..... which is approximate

C = arccos(0.131016042780749)

C = 82.4716905247836

C = 82 degrees

lets change it to a different question

does [tex]\frac{20}{14}=\frac{80}{56}[/tex]

Answer:

House coordinate = (5, 1)

Library coordinate = (10, 13)

Step-by-step explanation:

Given :

House coordinate = (5, 1)

Library coordinate = (10, 13)

Distance between house snd library :

Distance = sqrt[(x2 - x1)² + (y2 - y1)]

x1 = 5, x2 = 10, y1 = 1, y2 = 13

Distance = sqrt[(10 - 5)² + (13 - 1)²]

Distance = sqrt[(5² + 12²)]

Distance = sqrt(25 +144)

Distance = sqrt(169)

Distance = 13

Answer:

x = 4

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = [tex]\frac{1}{\sqrt{2} }[/tex]

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{4\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

[tex]\sqrt{2}[/tex] x = 4[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )

x = 4

Answer:

[tex]V=81\ \text{feet}^3[/tex]

Step-by-step explanation:

A wooden box has a square base

One side of the base is 3 feet

The height of this box is 3 times the length of one side of the base, h = 3(3) = 9 feet.

The volume of the box is given by :

[tex]V=A\times h[/tex]

A is area of base

For square base, A = side²

[tex]V=3^2\times 9\\\\=81\ \text{feet}^3[/tex]

So, the volume of this box is [tex]81\ \text{feet}^3[/tex]

Answer:

The coordinate is (0,1) .

Step-by-step explanation:

A linear equation is given to us and we need to find the point at which it will cut y axis . The given eqution is y - 4x = 1. We know that at y axis x coordinate is 0. So on substituting x = 0 , we have ;

Put x = 0 :-

⇒ y - 4x = 1

⇒ y - 4*0 = 1

⇒ y - 0 = 1 .

⇒ y = 1 .
