round to the hundredth 3.5262

Answer:

BC = 104

Step-by-step explanation:

By the SAS postulate, ΔBDA and ΔBDC are congruent, meaning that each of the corresponding sides are equal in length.

BD = BD

AD = CD

BA = BC

If we know BA = 21x - 1 and BC = 9x + 59, then we can set them equal to each other and solve for "x".

BA = BC

21x - 1 = 9x + 59

21x = 9x + 60                     Added 1 to both sides

12x = 60                             Subtracted 9x from both sides

x = 60/12                            Divided both sides by 12

x = 5                                   Reduced fraction, solved for "x"

To find BC, substitute x = 5 into the equation for BC.

BC = 9x + 59

BC = 9(5) + 59                    Substituted "x" for 5

BC = 45 + 59                      Multiplied 9 and 5

BC = 104                            Added, solved for BC

∴ BC = 104

Answer: The predicted number of penalty kicks = 12

Step-by-step explanation:

Given : The experimental probability of her making a penalty kick in soccer is 3/10 or 30%.

So, the proportion of penalty kicks she make = 0.3

Out of 40 penalty kicks, the predicted number of penalty kicks = 0.3 x 40

= 12

Hence, the predicted number of penalty kicks = 12

Answer:

40 kph

Step-by-step explanation:

I'm not to familiar with km but if it took you 30 minutes to travel 20km you would have to be going 40kph. It's basic math too. If you went 20 kph for 20km it would take you an hour to get there, but since they made it in 30 minutes, you just double the speed.

Answer:

20 miles

Step-by-step explanation:

If Maria has been riding for 2 1/2 hours and Aiden only for 2. That means that the first 4 miles she rode alone was for 1/2 hour. So that is the rate.

1/2 hour for every 4 miles

Maria rode for 2 1/2 hours divided by 1/2 hours is 5. So 5 x 4mi = 20 miles

Answer:

20 miles

because 4 miles= 1/2 hr

The Answer Is 74. Your Welcome

Answer:

21. is 18 dollars

22. is 75 dollars

Step-by-step explanation:

Answer:

21. $18.00

22. $75.00

Step-by-step explanation:

21. you can first start by seeing that since two pairs of socks are $6, then one pair must be $3. So, by multiplying 6 by 3, you would get 18 which would show that the socks would cost $18.

22. By dividing 15 by 3, you can deduce that an hour of cleaning would yield $5. So, by multiplying that by 15, she would earn $75.

Answer:

4x^6

Step-by-step explanation:

Area of the square pasture = L² where:

L is the

length of one side of the pasture

Given

L = 2x³

Area of the pasture = (2x³)²

Area of the pasture =2x³•2x³

Area of the pasture = 4x^{3+3}

Area of the pasture = 4x^6

Hence the area of the pasture is 4x^6

Answer:

x=2

Step-by-step explanation:

Set up a ratio

6/(x+1)=10/(2x+1)

cross multiply

6(2x+1)=10(x+1)

12x+6=10x+10

12x-10x=10-6

2x=4

Answer:

x is equal to 3 and -0.25

Step-by-step explanation:

The answer can be found by factoring the equation and solving for zero:

[tex]8x^2 = 6 + 22x\\4x^2 = 3 + 11x\\4x^2 - 11x - 3 = 0\\4x^2 -12x + x - 3 = 0\\4x(x - 3) + (x - 3) = 0\\(4x + 1)(x - 3) = 0[/tex]

So x is equal 3 and -0.25

Answer:

X = 37.6

Step-by-step explanation:

Cos(62°) = X/80

80cos(62°) = X

X = 80cos(62°)

X = 37.6

Answer: M<2=38 m<3=142 m<4=38

Step-by-step explanation:

142+142+38+38=360-Both side

142+38=180- one side

180-142=38

Answers:

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

Explanation:

Angle 1 is given to be 142 degrees. Angle 3 is equal to this measure since vertical angles are congruent. Vertical angles are angles that form when you have an X shape like this. They are opposite angles.

Angles 2 and 4 are the other pair of congruent vertical angles. This means angle 2 = angle 4.

Note how angle 1 and angle 2 form a straight line. These two angles add to 180.

(angle1) + (angle2) = 180

(142) + (angle2) = 180

angle2 = 180-142

angle2 = 38 degrees

angle 4 is also 38 degrees since angles 2 and 4 are a congruent vertical angle pairing.

Answer:

136

Step-by-step explanation:

triangles CAB and CED are similar, their sides are proportional

set up a proportion:

[tex]\frac{51}{144-x}[/tex] = [tex]\frac{3}{x}[/tex]

cross-multiply:  51x = 3(144 - x)

                         51x = 432 - 3x

                         54x = 432

                          x = 8

Plug in:

144 - 8 = 136

Answer:

Slope of the graph is steeper.

The answer is: [tex]\mathbf{Slope=\frac{1}{3}}[/tex]

Step-by-step explanation:

First we will find slope of the graph.

The formula used to find slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We need to find two points from the graph to find the slope.

Let we take point 1 (-2,1) and point 2 (1,2)

We will have: [tex]x_1=-2, y_1=1, x_2=1, y_2=2[/tex]

Now finding slope of the graph

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{2-1}{1-(-2)} \\Slope=\frac{2-1}{1+2}\\Slope=\frac{1}{3}[/tex]

So, slope of the graph is: [tex]\mathbf{Slope=\frac{1}{3}}[/tex]

Now, we will find slope of Linear function.

It has x-intercept of 1 and y-intercept of -2

x-intercept means y=0

So, the point will be: (1,0)

y-intercept means x=0

So, the point will be: (0,-2)

We will have: [tex]x_1=1, y_1=0, x_2=0, y_2=-2[/tex]

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-2-0}{0-(1)} \\Slope=\frac{-2-0}{0+1}\\Slope=\frac{-2}{1}\\Slope=-2[/tex]

So, the slope of linear function is: [tex]\mathbf{Slope=-2}[/tex]

Now, we need to find which of the slope is steeper.

The larger the value of slope, more steeper it is:

Now, comparing the slopes:

The slope of the graph is: [tex]\mathbf{Slope=\frac{1}{3}}[/tex]

The slope of linear function is: [tex]\mathbf{Slope=-2}[/tex]

We know that, [tex]\frac{1}{3}>-2[/tex]

So, Slope of the graph is steeper.

The answer is: [tex]\mathbf{Slope=\frac{1}{3}}[/tex]

Answer: X=y/2-5/2

Step-by-step explanation:

Answer:

x=1/2y+(−5/2) or x=y-5/2

Step-by-step explanation:

Step 1: Flip the equation.

2x+5=y

Step 2: Add -5 to both sides.

2x+5+−5=y+−5

2x=y−5

Step 3: Divide both sides by 2.

2x/2=y−5/2

x=1/2y+(−5/2) or x=y-5/2
