Answer:

11 1/4

Step-by-step explanation:

Add all whole numbers first

4+4+2= 10

Then add the numerators since the denominator is the same

1/4 + 3/4 + 1/4= 5/4

5/4= 4/4 and 1/4 4/4 is a whole number = 1

10+1 = 11

Answer:

11 1/4

Step-by-step explanation:

4 + 4 + 2 = 10

1/4 + 3/4 + 1/4 = 5/4

5 divided by 4 = 1.25

0.25 as a fraction is 1/4

1.25 as a fraction is 1 1/4

So u add the 1 to 10 which is 11

Now u put the answer together which is 11 1/4

What is the answer to the question?

Jobisdone [24]

Answer: C.

Step-by-step explanation:

An isosceles triangle is a type of triangle that has two identical sides and angle measures. Knowing that the two sides creating the 44 degree angle are equal, you can also know that both remaining angles are equal.

All three angles in a triangle must add to 180, so you can solve for f through this equation:

2f + 44 = 180

2f = 136

f = 68

Justin recently drove to visit his parents who live 96 miles away. On his way there his average speed was 20 miles per hour fast

never [62]

Answer:

Justin's average speed to his parents' house: x= 40mph

Justin's average speed from his parents' house: x+20=60 mph

Step-by-step explanation:

Let the average speed be x +20

Then average speed from his parents' x

And the distance is S=96

Then we know :

$\displaystyle \frac{S}{x+20} +\frac{S}{x} =4 \\\\\\ \frac{96}{x+20} +\frac{96}{x}=4 \ |\div 4 \\\\\\ 24\bigg(\frac{1}{x+20} +\frac{1}{x} \bigg) =1 \\\\\\ 24\cdot \frac{x+x+20}{(x+20)x} =1 \ |\cdot (x+20)x \ \ \\\\\\48x+480=x^2+20x \\\\ x^2-28x-480=0 \\\\ \rm D=28^2+4\cdot 480=2704 =52^2 \\\\ \boxed{x_1=\frac{28+52}{2} =40} \\\\x_2=\frac{28-52}{2} =-12 \ \ \varnothing$

Justin's average speed to his parents' house: x= 40mph

Justin's average speed from his parents' house: x+20=60 mph

Quadrilateral WXYZ has vertices W(-4,-3), X(0,-1). Y(6,-2), Z(2,-4). Using properties of diagonals prove that WXYZ is a parallel

yanalaym [24]

Answer:

The diagonals are bisectors of each other and meet at (1, -5/2) but are not congruent, so WXYZ is a parallelogram and not a rectangle

Step-by-step explanation:

for parallelograms.

the diagonals intersect at the midpoints

W X

Z Y

Diagonals are WY and XZ

WY : (-4, -3) to (6, -2)

midpoint is [(-4 + 6)/2 , (-3 - 2)/2 ] = ( 1, -5/2 )

XZ : (0, -1) to (2, -4)

midpoint is [ (0 + 2)/2 , (-1 + -4)/2 ] = (1, -5/2)

The diagonals are bisectors of eachother.

Next show that these diagonals are not congruent.

length of WY = root ( (-4 - 6)^2 + (-3 - (-2))^2 )

WY = root ( 100 + 1)

WY = root(101)

length of XZ = root ( (0 - 2)^2 + ( -1 - -4)^2 )

XZ = root (4 + 9) = root (13)

we see that WY is not equal to XZ

...

so .. quadrilateral WXYZ is a parallelogram but not a rectangle.

Enter the range of values for x

Pavlova-9 [17]

<em>Greetings from Brasil...</em>

See the attached figure. The smaller the θ angle, the smaller the AB side will be. If the angle θ = 90º, then AB = 25. As θ < 90, then AB < 25

5X - 10 < 25

5X < 25 + 10

X < 35/5

X < 7

The AB side can be neither zero nor negative. So

5X - 10 > 0

5X > 10

X > 10/5

X > 2
