Answer:

The number of runners that finished in first place , second place and third place are 7 , 13 and 10 respectively.

Step-by-step explanation:

Let the no. of runners fished at first place be x

Let the no. of runners fished at second place be y

Let the no. of runners fished at third place be z

We are given that Lakeland High School had 30 individual-  event placers

So, x+y+z=30 -----1

First-place finishers score 7 points

So, Total score of x runners = 7x

Second-place finishers score 4 points

So, total score of y runners = 4y

Third-place finishers score  1 point.

So, total score of z runners = z

We are given that 30 individual-  event placers score a total of 111 points

So, 7x+4y+z=111 ----2

We are also given that  The number of first- and second-place finishers was twice the  number of third-place finishers.

x+y=2z ---3

Substitute the value from 3 in 1

x+y+z=30

2z+z=30

z=10

Substitute the value of z in 1 and 2

x+y=20 ----4 and 7x+4y=101 ---5

Substitute the value of x from 4 in 5

7(20-y)+4y=101

140-7y+4y=101

140-3y=101

39=3y

`13=y

Substitute the value of y and z in 1

x+13+10=30    

x=7

Hence the number of runners that finished in first place , second place and third place are 7 , 13 and 10 respectively.

Step-by-step explanation:

For two triangle to be congruent,there must be any three sides or angle including congruent

Congruent triangles have three pairs of corresponding sides that are congruent, while two triangles that have three pairs of corresponding congruent angles are similar and not necessary congruent. Therefore:

Recall:

1. When the two triangles have the three pairs of corresponding angles that are congruent, they can only be said to be similar. They have the same shape but may be of different sizes.

Therefore, statement 1 is FALSE.

2. Knowing that three pairs of corresponding sides of two triangles are congruent, it is enough to prove that both triangles are congruent to each other.

Therefore, statement 2 is TRUE.

Answer:

11 months

Step-by-step explanation:

50m + 75 >= 600

just solve the inequality like how you would solve an equation, by inverse operations and simplifying

50m + 75 >= 600

        -75       -75

50m >= 525

/50        /50

m>= 10.5

just round up, because 0.5 of a month really isn't an answer

so 11 months

Step-by-step explanation:

Answer:

Option (2)

Step-by-step explanation:

pH level of a substance is determined by the formula,

pH = - log[H+}

where [H+] is the hydrogen ion concentration

Let the [H+] ion concentration = a

a = -log[H+]

log[H+] = -a

[H+] = 1 × [tex]10^{-a}[/tex]

Here 'a' is between 7 and 14.

Which means an alkaline substance must have the concentration between [tex]1\times 10^{-7}[/tex] to  [tex]1\times 10^{-14}[/tex].

From the given options, [tex]5\times 10^{-12}[/tex] moles per liter lies in the given range.

Therefore, Option (2) will be the answer.

Katie's salary is increasing $250 per week.

Step-by-step explanation:

Answer:

The sequence that best represents the order during repaid of a fracture as as

follows

3. hematoma formation

4. fibrocartilaginous callus formation

2. bony callus formation

1. cartilage ossification

5. remodeling of woven (spongy) bone into compact bone

Step-by-step explanation:

When a bone is fractured, the first step following a bone fracture is hematoma formation.

Hematoma formation is formed when a little blood escapes from the blood vessels and remains in the skin's thickness, creating a blue spot. The hematoma is an effusion of blood that occurs deeper under the skin.

From there, the formation of tissues begins from end to end of the broken bones. It is a reorganization of the bone tissue (the bone itself), allowing the consolidation of a fractured bone. This bone formation welds the two parts of the broken bone together for a particular period depending on the patient's bone tissue condition. This bone callus will form in two episodes.

1) There first appears a fibrocartilaginous callus, also called connective callus, which allows the fracture to heal in a few weeks. It is an immature bone.

2) In a second step, this immature bone is gradually replaced by another bone (calcified/bony) resembling the bone which has been fractured.

From there, the ossification of the callus occurs where the bony callus is further replaced by woven spongy bones to form a stronger stabilizing collar.

Finally, the remodeling of woven (spongy) bone into compact bone takes place. Lamellar bones are replacing these woven spongy bones.

Answer:

12/20=3/5   5/20=1/4 so the answer would be 12/20 + 5/20

Hope this helped you!!

Equivalent fractions for [tex]\boldsymbol{\frac{3}{5},\frac{1}{4}}[/tex] are [tex]\boldsymbol{\frac{12}{20},\frac{5}{20}}[/tex] respectively.

A fraction is a portion of another or, more broadly, a set of equal pieces. Equivalent fractions are fractional that have the same value notwithstanding their appearance.

[tex]\boldsymbol{\frac{3}{5}=\frac{3\times 4}{5\times 4}}[/tex]

  [tex]=\frac{12}{20}[/tex]

[tex]\boldsymbol{\frac{1}{4}=\frac{1\times 5}{4\times 5}}[/tex]

  [tex]=\frac{5}{20}[/tex]

So, equivalent fractions for [tex]\boldsymbol{\frac{3}{5},\frac{1}{4}}[/tex] are [tex]\boldsymbol{\frac{12}{20},\frac{5}{20}}[/tex] respectively.

Step-by-step explanation:

Answer: brady earned 135 dollars this week.

Step-by-step explanation: 7.50 X 10 + 5 X 12 is 135.

The x coordinates, 6 and 6, add to 6+6 = 12. Then we cut this in half getting 12/2 = 6.

The x coordinate of the midpoint is 6.

The y coordinates, 7 and -5, add to 7+(-5) = 2. Which cuts in half to get 2/2 = 1.

The y coordinate of the midpoint is 1.

Put together, the midpoint is located at (6,1)
