Wolfrich lived in Portugal and Brazil for a total period of 141414 months in order to learn Portuguese. He learned an average of 130 new words per month when he lived in Portugal and an average of 150 new words per month when he lived in Brazil. In total, he learned 1920 new words. How long did Wolfrich live in Portugal, and how long did he live in Brazil?
Answers
Answer:
The total period should be 14 months and not 141414 months.
Thus answer will be: number of months spent in Brazil is 5 months and he spent 9 months in Portugal.
Step-by-step explanation:
Let the number of months he lived in Portugal be X and the number of months he lived in Brazil be Y: Thus we have:
X + Y = 14 months.
He learned an average of 130 new words per month when he lived in Portugal: 130 x number of months (X) = 130X
and an average of 150 new words per month when he lived in Brazil: 150 x number of months in Brazil (Y) = 150Y.
Thus we have 130X + 150Y = 1920
Since X + Y = 14: make X subject of formula: X = 14 - Y. then substitute this for X in the equation below
130X + 150Y = 1920
130(14-Y) + 150Y = 1920
1820 - 130Y + 150Y = 1920
150Y - 130Y = 1920 - 1820
20Y = 100
Y = 100/ 20 = 5 months
Thus number of months spent in Brazil is 5 months. To find the number of months spent in portugal, use the first equation:
X + Y = 14 where Y is 5
X = 14 - 5 = 9 months. Thus he spent 9 months in Portugal
what mathematical process do you use to find the new size using the scale factors? (select all that apply)
1. multiplication
2. addition
3. proportions
4. subtraction
5. division
Answers
Answer: 1. multiplication
Step-by-step explanation:
Suppose that you want to change an object with length L with a scale factor a, then the lenght of the rescaled object will be:
L' = a*L
Then the correct option is 1) multiplication.
Notice that sometimes you may find that the scale factor is a number like 1/5 and when you find the new lenght you will end with something like:
L' = L/5 that seems like a division, but this is actually the multiplication between L and 1/5.

Fill in the y values of the t–table for the function y=\root(3)(x)
Answers
You can use a graphing calculator to have a function y = x^(1/3) and see what the y values are for the particular x values shown. Alternatively you can compute each input to get (-8)^(1/3) = -2, and (-1)^(1/3) = -1 and so on. The exponent of 1/3 is another way of writing cube root.
The cube root is the opposite of cubing something. If we go from 2 to 2^3 = 8, then reversing this has us go from 8 to 2. Think of a block of clay that is 2 by 2 by 2. The volume of this block is 8 cubic units. If you want to find the side length, then you would apply the cube root (or do guess and check).

Craig and Danny are planning to tr y out for the basketball team and one of the criteria fro the selection is based on free throw shots. Craig makes 55% of the free throwshe attempts, while Danny makes 71% of the free throws he attempts. Which is more likely: that Craig will miss two free shot throws in a row, or that Danny will make three free throw shots in a row?
Answers
Answer:
It is more likely that Danny will make three free throw shots in a row.
Step-by-step explanation:
The probabilities of Craig and Danny making the throw they attempt, is given as:
Probability that Craig will make the throw = 55% = 0.55
Probability that Danny will make the throw = 71% = 0.71
Now, the probabilities that they will miss the throw can be found out by subtracting the probabilities, that they can make the throw, from 1.
Probability that Craig will miss the throw = 1 - 0.55 = 0.45
Probability that Danny will miss the throw = 1 - 0.71 = 029
Now,
Probability that Craig will miss two throws in a row = (0.45)(0.45) Probability that Craig will miss two throws in a row = 0.2025
And,
Probability that Danny will make three throws in a row = (0.71)(0.71)(0.71)
Probability that Danny will make three throws in a row = 0.3579
Since, the probability of Danny making three throws in a row is higher than the probability of Craig missing two throws in a row.
Thus, it is clear that, it is more likely that Danny will make three free throw shots in a row.
Tim's phone service charges $24.93 plus an additional $0.21 for each text message sent per month. If
Tim's phone bill was $30.18, which equation could be used to find how many text messages, x, Tim
sent last month?
Answers
Answer:
x = 24
Step-by-step explanation:
T = 24.93 + 0.21x Substitute 30.18 for T
30.18 = 24.94 + 0.21x
-24.94 - 24.94 Subtract 24.94 from both sides
5.24 = 0.21x Divide both sides by 0.21
x = 24.95 ≈ 24 because you can't have a partial text message.

1-2c = -8
-8/7r = 6
4-4 (4-x) -4x = 18x
1/5m + 3 = 7/5m
Answers
Answer:
1. c = 9/2
2. r = 21/4
3. x = -2/3
4. m = 5/2
Step-by-step explanation:
1.
1 - 2c = -8
Subtract 1 from both sides to isolate the variable:
-2c = -8 - 1 = -9
Divide by -2 to further isolate the variable:
c = (-9) / (-2) = 9/2
So, the answer is c = 9/2.
2.
-8/7r = 6
To isolate the variable, divide both sides by -8/7:
r = (-6) / (-8/7)
Remember that when dividing fractions, it's the same as multiplying by the reciprocal of the divisor, so:
r = (-6) / (-8/7)
r = (-6) * (-7/8) = 42/8 = 21/4
So, the answer is r = 21/4.
3.
4 - 4 * (4 - x) - 4x = 18x
We need to use order of operations and expand the 4 * (4 - x) part first:
4 * (4 - x) = 16 - 4x
Put this back in:
4 - (16 - 4x) - 4x = 18x
4 - 16 + 4x - 4x = 18x
Combine like terms:
-12 = 18x
Divide by 18 on both sides:
x = -12/18 = -2/3
So, the answer is x = -2/3.
4.
1/5m + 3 = 7/5m
Subtract 1/5m from both sides:
3 = 7/5m - 1/5m = 6/5m
Divide both sides by 6/5:
m = 3 ÷ (6/5) = 3 * (5/6) = 15/6 = 5/2
So, the answer is m = 5/2.
Answer:
1. c = 9/2
2. r = -21/4
3. x = -2/3
4. m = 5/2
Step-by-step explanation:
1-2c = -8
1 + 8 = 2c
9 = 2c
c = 9/2
-8/7r = 6
r = 6 × 7/-8
r = 3 × 7/-4
r = -21/4
4-4 (4-x) -4x = 18x
4 - 16 + 4x - 4x = 18x
-12 = 18x
x = -12/18
x = -2/3
1/5m + 3 = 7/5m
3 = (7/5 - 1/5)m
3 = 6/5m
m = 3 × 5/6
m = 5/2

Use conversions to solve the problem. Jane wants to edge her garden with stone. All sides are equal. The stone costs $6 per yard. What is the perimeter of the garden? How much will it cost to buy the edging she needs?
Answers
Answer:
Perimeter: [tex]p = 4\cdot l[/tex], Total costs: [tex]C = 24\cdot l[/tex]
Step-by-step explanation:
The garden has a square form. Let be [tex]l[/tex] the length of any of the sides, measured in yards. The perimeter of the garden, measured in yards, is:
[tex]p = 4\cdot l[/tex]
Now, perimeter has a length unit and total costs of edging the garden, measured in US dollar, is:
[tex]C = \left(6\,\frac{USD}{yard} \right)\cdot 4\cdot l[/tex]
[tex]C = 24\cdot l[/tex]
A museum has 450 visitors each day. If they are open 5 hours, how many people do they see per hour?
Answers
Answer: 90 visitors per hour
Explanation: "Per hour" means in 1 hour, so we can rewrite the given statement using fractions as 450 visitors/5 hours = __visitors/1 hour.
To find out what goes in the bank, notice that we
have a 1 in the denominator of our second fraction.
So we want to find a fraction that is equivalent
to 450/5 that has a 1 in the denominator.
If we divide the numerator and denominator of 450/5 by 5,
we get the equivalent fraction 90/1 or 90 visitors/1 hour.
So now we have 90 visitors/1 hour = __visitors/1 hour.
So a 90 must go in the blank.
This means that the museum sees 90 visitors per hour.

find the circumference of the circle
Answers
Answer:
C
Step-by-step explanation:
2 x pi x r = circumfrence
2 x 7 x pi = 43.96
Answer: 43.96 m
Step-by-step explanation: To find the circumference of the circle shown here, start with the formula for the circumference of a circle which is shown below.
Circumference = 2πr
Notice that the radius of the circle is 7 meters.
So we can plug in 7 meters for r in the formula.
So we have (2)(π)(7m) which is equal to 14π m.
So the circumference of the circle shown here is 14π m.
Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.
So we have (14)(3.14) which is equal to 43.96.
So the circumference of the circle is
approximately equal to 43.96 m.

Juan analyzes the amount of radioactive material remaining in a medical waste container over time. He writes the function
f(x)=10(0.98) to represent the amount of radioactive material that will remain after x hours in the container.
Rounded to the nearest tenth, how much radioactive material will remain after 10 hours?
O 0.8 units
O 1.3 units
O 8.2 units
O 9.8 units
Answers
Answer:
Correct option: Third one -> 8.2 units
Step-by-step explanation:
Assuming that the function that models the amount of radioactive material remaining after x hours is:
f(x)=10*(0.98)^x
To find the amount of material after 10 hours, we just need to use x = 10 in the equation and find the value of f(x):
f(10) = 10*(0.98)^10
f(10) = 8.1707
Rounding to nearest tenth, we have f(10) = 8.2
Correct option: Third one
Answer:

quadrato equation
x²+5x+6=0
Answers
Answer:
x = - 3, x = - 2
Step-by-step explanation:
Given
x² + 5x + 6 = 0
Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 5)
The factors are + 3 and + 2, since
3 × 2 = + 6 and 3 + 2 = + 5, thus
(x + 3)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x + 2 = 0 ⇒ x = - 2
Answer:
x= -2 or -3
Step-by-step explanation:
First, you find the two factors that can replace +5 to enable you to factorize. To do this, you find the factors of +6 and check the factors that when added would give +5.
The factors are +2 and +3
x²+ 5x+6=0
x²+2x+3x+6=0
x(x+2)+3(x+2)=0
(x+2)(x+3)=0
x+2=0 or x+3=0
x= -2 or x= -3
∴x= -2 or -3

Efficient Homemakers Ltd. makes canvas wallets and leather wallets as part of a money making project. For the canvas wallets, they need three yards of canvas and two yards of leather. For the leather wallets, they need three yards of leather and two yards of canvas. Their production unit has purchased 36 yards of leather and 40 yards of canvas. Let x be the number of leather wallets and y be the number of canvas wallets. If the profit on a canvas wallet is $25 and the profit on a leather wallet is $40, write a function for the total profit on both wallets.
Answers
Answer: F(x, y) = 40x + 25y
Step-by-step explanation:
Given the following :
x = number of leather wallets
y = number of canvas wallets
PROFIT on canvas wallet = $25
PROFIT on leather wallet = $40
Function that calculates the total profit on both wallets:
Profit on each wallet type is the product of the profit per wallet and the number of wallet.
The total profit generated on each wallet type is given by :
F(x) = 40x - - - - (1) leather wallet
F(y) = 25y - - - - (2) canvas wallet
Adding (1) and (2) to get total profit on both wallets:
F(x, y) = 40x + 25y
