On Monday, the coldest temperature outside was 2 degrees Fahrenheit. On Tuesday, Ms. Perkins tells her students that the coldest

temperature outside has an absolute value of 4 degrees.
Rachel says that Tuesday’s coldest temperature could be greater than Monday’s coldest temperature.

Tom says that Tuesday’s coldest temperature could be less than Monday’s coldest temperature.

State whether each student’s statement is true or false, and justify your answers.

Answer:

Temperature on Monday was 2 degrees Fahrenheit.

Temperature on Tuesday was absolute value of 4 degrees Fahrenheit.

Absolute value is always a positive number but the actual temperature could have been positive or negative 4 degrees.

  • | ± 4 | = 4

If it was positive, then Rachel is correct, but if negative, then Tom is correct.

ANSWER:

Both of the students answer may be correct because it is not clear either it is + 4°F or - 4°F.

Two distinct planes __________ intersect in a pair of lines
hammer [34]
If the planes are parallel to one another then they will never intersect (assuming they are distinct planes as the question states).

Otherwise they will intersect along a single line.

Therefore the answer is NEVER - they can never intersect in a pair of lines.

Paddy and Anna each invest $2000 for 5 years.
Serga [27]

Answer: r= 1.22

Step-by-step explanation:

Formula for amount with simple interest = P(1+rt)

, where

P= principal value , r= rate of interest , t = time.

Given: P=  $2000, t= 5 years, r= 1.25% = 0.0125

A=2000(1+0.0125\times5)\\\\=2000(1.0625)=2125

Formula to compute compound amount : P(1+r)^t

=2000(1+r)^5

When both have same worth then

2000(1+r)^5=2125\\\\\\ (1+r)^5=\dfrac{2125}{2000}\\\\\\ (1+r)^5=1.0625

taking log on both sides , we get

5\ln (1+r)=\ln 1.0625\\\\\\ 5\ln (1+r)=0.0606246\\\\\\ \ln (1+r)=0.012125\\\\\\ 1+r=e^{0.005266}\\\\\\ 1+r=1.0122\\\\ r=0.0122\\\\ \\ r=1.22\%

Hence, Value of r= 1.22

Last fall, a middle school took a group of students on a trip to Space Camp, which is 360 miles away. The bus that they took to
mezya [45]

Answer:

The bus travelled 60 miles in 1 hour.

Step-by-step explanation:

To solve this problem we need to calculate the average speed at which the bus travelled. This is given by the distance travelled divided by the time that they took to get there. So we have:

average speed = distance/time

average speed = 360/6

average speed = 60 miles/h

Therefore in 1 hour they travelled 60 miles.

I have k quarters, five less quarters than nickels and one more than twice as many dimes as quarters. Find the value of the coin
Alenkinab [10]

Answer:

(35k + 20) cents

Step-by-step explanation:

First of all, let us have the value of each unit:

1 quarter = 25 cents

1 nickel = 5 cents

1 dime = 10 cents

Given that number of quarter = k

Quarters are 5 lesser than Nickels, so number of nickels = k+5

One more than twice as many dimes as quarters:

k = 2 \times Number of Dimes + 1

So, number of dimes = \frac{1}{2}(k-1)

Value of quarters = 25 \times k cents

Value of nickels = 5 \times (k+5) = (5k+25)\ cents

Value of dimes = \frac{1}{2}(k-1) \times 10 = (5k-5)\ cents

So, total value of coins =

25k + 5k +25 +5k-5\\\Rightarrow (35k+20)\ cents
