Answer:

12:25

Step-by-step explanation:

Número de alunos matriculados: 2.500

Número de alunos selecionados: 1.200

A proporção que representa o número total de alunos selecionados em relação ao número de alunos matriculados é dada como:

Número de alunos selecionados: Número de alunos matriculados

= 1200: 2500

= 12 : 25

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.

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:

  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:

Given costs:

Sum of the costs:

Average cost is sum divided by number:

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:

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: 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 .

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.

Answer:

7.38

Step-by-step explanation:

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:

The second option is correct

Step-by-step explanation:

Here, we want to check which of the options is true of the plot

Now, let us take a look at the first option

When we talk of the slope in this case, we are simply talking of the amount he needs to save for each of the months

As we can see, for the initially, he had 900 to save, so what this mean is that at the very beginning, the amount of money he had to save is 900

Hence, the total money he had to save is $900 and this makes the second option correct
