Joe tracked the height of his Dalmatian puppy from age 13 weeks to 25 weeks. He graphed the data and determined the line of best fit is y = 1.12x + 28.78 where x is the age in weeks and y is the height in centimeters. How old was the puppy when he was 54 centimeters tall? Round to the nearest tenth.

a. 22.5 weeks
b. 28.2
c. 73.9
d. 89.3

Answers

Answer 1

Answer:

22.5 weeks

Step-by-step explanation:

y = 1.12x + 28.78 represents the height of the puppy.  Here that height is 54 cm:

Then 54 = y = 1.12x + 28.78

Combining the constants, we get 1.12x = 25.22.  Dividing both sides by 1.12, x turns out to be 22.5 weeks.

A: Find the interest earned
B: Find the balance of the account

Answers

So this is a simple interest problem

Amount=principal(starting amount) * rate * time(In years)

So A= 300*0.04*3
A =36
So the interest earned was 36$ but since the balance started with 300$ you have to add 36$ to the old balance to find your new balance
Therefore your new balance would be 336$

Answers

Answer:

[tex]t = 5[/tex]

Step-by-step explanation:

By the mid-segment theorem of triangles,

[tex]VX= \frac{1}{2} YZ[/tex]

We substitute the expressions in terms of t.

[tex]10t = \frac{1}{2} (t + 95)[/tex]

We multiply through by 2 to get:

[tex]20t = t + 95[/tex]

Subtract t from both sides:

[tex]20t - t = 95[/tex]

[tex]19t = 95[/tex]

Divide both sides by 19:

[tex]t = \frac{95}{19} [/tex]

Answers

Final answer:

To determine the proper number of significant figures in a calculation, follow the rules for addition/subtraction and multiplication/division, and round the final answer to the proper number of significant figures.

Explanation:

To determine the proper number of significant figures in a calculation, follow these rules:

Addition and subtraction: The result should have the same number of decimal places as the number with the fewest decimal places.Multiplication and division: The result should have the same number of significant figures as the number with the fewest significant figures.Rounding: Round the final answer to the proper number of significant figures.

Using these rules, the proper number of significant figures for the given calculations are:

A.) 320.80 - (6101.3 / 1.8) = 300

B.) [(286.4 x 105) - (1.300 x 103)] x 2.8951 = 839000

C.) (0.0041 x 26000.0) + (2811 x 15) = 40000

D.) 863 x [1251 - (3.11 x 109)] = -1.7742e12

Write the expression "N is the same as 6 reduced by 2" as a number sentence.

Answers

Answer:

N = 6 - 2

Step-by-step explanation:

Take each part of the word expression and translate it:

"N"   =>  N        ("N" is a variable that represents a number you don't know)

"is the same as"   =>  =       ("the same" means equals)

"6 reduced by 2"   =>  6 - 2          ("reduced" means use subtraction "-")

Put the sentence back together in the same order.

N = 6 - 2

If you wanted to find "N", you can simplify by doing 6 - 2.

N = 4

What is the measure of angle X? 56° 41°

Answers

Question:

What is the measure of angle X?

The image of the measurements is attached below:

Answer:

The measure of angle x is 83°

Explanation:

Since, Vertical angles have equal measure,

Let us consider that the angle opposite to 41° is ∠y and they are equal.

i.e, ∠y = 41°

Since, the angles in a straight line add up to 180°, we have,

∠x + ∠y + 56° = 180°

Substituting the value ∠y = 41°, we have,

∠x + 41° + 56° = 180°

Adding the terms, we get,

∠x + 97° = 180°  

Subtracting both sides by 97°, we get,

∠x = 83°

Thus, the measure of ∠x is 83°

83 degrees

doug has 45 coins worth $9.00. The coins are all quarters or dimes. How many of each type of coin dose doug have?

Answers

Doug have 30 quarters and 15 dimes.

Step-by-step explanation:

Given,

Number of coins = 45

Worth of coins = $9.00 = 9.00*100 = 900 cents

Each quarter = 25 cents

Each dime = 10 cents

Let,

x be the number of quarters

y be the number of dimes

According to given statement;

x+y=45            Eqn 1

25x+10y=900   Eqn 2

Multiplying Eqn 1 by 10

[tex]10(x+y=45)\\10x+10y=450\ \ \ Eqn\ 3[/tex]

Subtracting Eqn 3 from Eqn 2

[tex](25x+10y)-(10x+10y)=900-450\\25x+10y-10x-10y=450\\15x=450[/tex]

Dividing both sides by 15

[tex]\frac{15x}{15}=\frac{450}{15}\\x=30[/tex]

Putting x=30 in Eqn 1

[tex]30+y=45\\y=45-30\\y=15[/tex]

Doug have 30 quarters and 15 dimes.

Doug has 30 quarters and 15 dimes.

Let

x = number of quarters

y = number of dimes

The total number of coins is 45. Therefore,

Total number of coins:x + y = 45

Total amount of the coins is $9. Therefore,

Total cost of the coins:0.25x + 0.1y = 9

Therefore,

x + y = 45

0.25x + 0.1y = 9

0.1x + 0.1y = 4.5

0.25x + 0.1y = 9

0.15x = 4.5

x = 4.5 / 0.15

x = 30

simplify the expression 6-2x+5+4x

Answers

Answer:

11 + 2x

Step-by-step explanation:

First you will want to separate like variables, so (6, 5) and then (-2x, 4x)

Then you will use the signs to do the math. You can move everything to help visualize the solution easier.

6+5+4x-2x

6+5 = 11

4x-2x = 2x

Because you cannot add or subtract a variable with a non variable, and both numbers are positive you end up with

11 + 2x

The expression 6-2x+5+4x simplifies to 11 + 2x by combining like terms: the constants (6+5=11) and the variables (-2x+4x=2x).

To simplify the expression 6-2x+5+4x, we start by combining like terms. Combining the constant terms (6 and 5) and the variable terms (-2x and 4x), we get:

Constant terms: 6 + 5 = 11

Variable terms: -2x + 4x = 2x

Thus, the simplified expression is 11 + 2x.

If inflation from last year to this year was 2% and a pair of designer jeans sold for $75 last year, what would you expect to pay for them this year?

Answers

Answer:

$76.5

Step-by-step explanation:

We have been given that inflation from last year to this year was 2% and a pair of designer jeans sold for $75 last year. We are asked to find the price of pair of designer jeans this year.

An inflation of 2% will increase the price of pair of jeans by 2%, so price of pair of jeans this year would be $75 plus 2% of $75.

[tex]\text{Price of pair of jeans this year}=\$75+\$75\times\frac{2}{100}[/tex]

[tex]\text{Price of pair of jeans this year}=\$75+\$75\times0.02[/tex]

Therefore, the price of pair of jeans would be $76.5 this year.

A concert hall has three sections: the main floor, the balcony, and the gallery. For a recent concert, 1020 tickets were sold. There were twice as many balcony tickets sold as gallery tickets, and 225 more main floor tickets than balcony tickets. If g represents the number of gallery tickets sold, which expressions represents this situation?

Answers

Answer:

Let the number of balcony seats be b

Let the number of gallery tickets be g

Let the number of main floor tickets be m

b + g + m  = 1020

b = 2g

m = b + 225

The number of balcony tickets = 318

The number of gallery tickets = 159

The number of main floor tickets = 543

Step-by-step explanation:

Let the number of balcony seats be b

Let the number of gallery tickets be g

Let the number of main floor tickets be m

i) Therefore we can write b + g + m  = 1020

ii) there were twice as many balcony tickets sold as gallery tickets

   therefore b = 2g      [tex]\Rightarrow[/tex]  g = 0.5b

iii) there were 225 more main floor tickets than balcony tickets

   therefore m = b + 225

iv) using equation ii) and equation iii) in equation i) we can write

     b + g  + m = b + 0.5b + b + 225  = 1020      [tex]\Rightarrow[/tex] 2.5b  = 795     [tex]\Rightarrow[/tex]  b = 318

v) g  = 0.5 b  = 0.5 [tex]\times[/tex] 318 = 159

vi) m = b + 225 = 318 + 225 = 543

Answer:

D. Gallery: g

Balcony: 2g

Main Floor: 2g+225

Step-by-step explanation:

Gallery is g

Balcony had 2 times as many tickets than Gallery so 2•g (2•gallery)

Main floor had 225 more tickets than Balcony so Balcony’s equation plus 225 tickets. 2g + 225
