[tex]distance = \sqrt{(x _{1} - x _{2})^{2} + {(y _{1} - y _{2})}^{2} } \\ = \sqrt{ {( - 2 - 6)}^{2} + {(4 - ( - 4))}^{2} } \\ = \sqrt{64 + 64} \\ = \sqrt{128} \: units[/tex]

Answer:

A. x = 8.

B. x = 31.

C. x = 32.

Step-by-step explanation:

Here. the sum of the 2 parallel sides of the trapezoid = 2 * length of the middle line segment.

MN + RS = 2PQ

32+ x = 2*20

x =  40 - 32

x = 8.

MN + RS = 2PQ

20 + 42 = 2PQ

2x =  62

x = 31

MN + RS = 2PQ

22 + 42 = 2PQ

2x =  64

x = 32.

Answer:

1 to 30 seconds

Step-by-step explanation:

3 seconds increases your speed from 32 to 35 miles per hour

Hence 3 seconds = 3 miles per hour(35-32 miles)

1 second = 1 mile

The function for the increase per mile is therefore:

f(x)= 1x

Where x is number of seconds travelled on the highway

The domain of a function are the possible input values for x. Since the speed limit on the highway is 65 miles, the input values for x cannot be more than 30 seconds(current speed is 35 miles per hour, 65-35=30)

Given:

Three corner points of a triangular garden are (0,3),(3,0), and (4,3).

To find:

The area of the garden.

Solution:

We know that, area of a triangle is

[tex]A=\dfrac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|[/tex]

Let a denote the area of the garden, in square units.

Three vertices of the triangular garden are (0,3),(3,0), and (4,3). So, area of the triangular garden is

[tex]a=\dfrac{1}{2}|0(0-3)+3(3-3)+4(3-0)|[/tex]

[tex]a=\dfrac{1}{2}|0(-3)+3(0)+4(3)|[/tex]

[tex]a=\dfrac{1}{2}|0+0+12|[/tex]

[tex]a=\dfrac{1}{2}\times 12[/tex]

[tex]a=6[/tex]

Therefore, the area of the garden is a=6 square units.

Step-by-step explanation:

☄ [tex] \underline{ \underline{ \text{Question }}}: [/tex] The ratio of new houses to antique houses in a village is 4 : 5 . If there are 12 new houses , how many antique houses are there ?

☄[tex]\underline{ \underline{ \text{Solution}}} : [/tex]

✏ Let , the number of antique houses in a village be ' x ' .

Then , According to the question :

[tex] \sf{ \frac{Number \: of \: new \: houses}{Number \: of \: antique \: houses} \: = \: \frac{4}{5}} [/tex]

⤑[tex] \sf{ \frac{12}{x} = \frac{4}{5}} [/tex]

Apply cross product property

⤑[tex] \sf{4 \times x = 12 \times 5}[/tex]

⤑[tex] \sf{4x = 60}[/tex]

⤑[tex] \sf{ \frac{4x}{4} = \frac{60}{4}} [/tex]

⤑[tex] \sf{x = 15}[/tex]

So, The number of antique houses in a village is 15.

Answer:

5.7 beads

Step-by-step explanation:

Marissa wants to sort 80 beads into 2 cases. The red case has 6 compartments, and the blue case has 8 compartments.

We are told in the Question that:

the compartments in each case hold the same number of beads and none are left over

Hence, let the number of beads in each compartments = x

Therefore:

8x + 6x = 80 beads

14x= 80 beads

x = 80 beads/14

x = 5.7142857143 beads

x ≈ 5.7 beads

Hence, she can sort the beads into 5.7 beads per compartments

Answer:

chose any thang

Step-by-step explanation:

Answer:

Correct option is (a)

Step-by-step explanation:

According to question in the triangle ΔJKL

JK = 9 and KL =4

according to the condition of triangle sum of two sides must be greater than the third side

Here sum of its two sides is 9 + 4 = 13

⇒ third side must be greater than 13 say 13.2 = JL

therefore, perimeter of triangle ΔJKL is

JK + KL + JL = 9 + 4 + 13.2 = 26.2

Therefore correct option is (a)

Answer: [tex]\dfrac{7}{69}[/tex] of height has been increased in second jump from the first jump.

Step-by-step explanation:

In first meet, height of best jump = 414 feet

In second meet, height of best jump = 456 feet

Increase in height = 456 feet - 414 feet

= 42 feet

The fraction of increased in height = [tex]\dfrac{\text{Change in height}}{\text{previous height}}[/tex]

[tex]=\dfrac{42}{414}\\\\=\dfrac{7}{69}[/tex]

Hence, [tex]\dfrac{7}{69}[/tex] of height has been increased in second jump from the first jump.

Answer: 10 minivans .

Step-by-step explanation:

Given: There are 35 fourth graders and 40fifth graders in the Robotics Club.

Total people = 35+40 = 75

Since each minivan can only hold 8 people.

Number of minivan required = (Total people) ÷ 8

= 75 ÷ 8

= 9.375≈ 10

Hence, the school needs to rent approx. 10 minivans .

Answer:

  DJ = 48

Step-by-step explanation:

The centroid (J) divides the median into parts that have the ratio 2:1.

  DJ : JH = 2 : 1

  DJ : (DJ +JH) = 2 : (2+1)

  DJ : DH = 2 : 3

  DJ = (2/3)DH = (2/3)(72)

  DJ = 48

Step-by-step explanation:

We have the points (0, 0) and (8, 14).

Rise between the points = 14 - 0 = 14.

Run between the points = 8 - 0 = 8.

Slope of Line

= Rise/Run = 14/8 = 1.75.

The estimated sum of  945 + 573 + 617 by rounding each number to the nearest hundred is 2100.

We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, Are the sum of three integers 945, 573, and 617.

Now, 945 rounded to the nearest hundred is 900, 573 rounded to the nearest hundred is 600 and 617 rounded to the nearest hundred is 600.

Therefore,  the sum of 945 + 573 + 617 by rounding each number to the nearest hundred is 900 + 600 + 600.

= 2100.
