The given expression is(m+6)÷(2−5)

Now put m=9 & apply BODMAS rule then we get,

⇒(m+6)÷(2−5)

(m+6)÷(2−5) =(9+6)÷(2−5)

(m+6)÷(2−5) =(15)÷(2−5)

(m+6)÷(2−5) =(15)÷(−3)

(m+6)÷(2−5) =15/−3

(m+6)÷(2−5) =−5​

Thus, the value of (m+6)÷(2−5) for m=9 is −5

The given expression is−5t+12−1/2t

Now put t=−10 & apply BODMAS rule then we get,

⇒−5t+12−1/2t

−5t+12−1/2t =−5(−10)+12−1/2(−10)

−5t+12−1/2t =50+12−1/2(−10)

−5t+12−1/2t =50+12−(−5)

−5t+12−1/2t =50+12+5

−5t+12−1/2t =50+17

−5t+12−1/2t =67

​Thus, the value of −5t+12−1/2t for t=−10 is 67

Question. The hottest recorded day in Florida history was 109°F, which occurred on June 29, 1931 in Monticello. Convert this temperature to degrees Celsius. Round your answer to the nearest tenth of a degree.

Given: The hottest recorded day in Florida history was 109∘F, which occurred on June 29, 1931 in Monticello.

To Determine: Convert this temperature to degrees Celsius. Round your answer to the nearest tenth of a degree.

For converting this temperature to degrees Celsius we use 5/9(F−32)

It is given that the hottest recorded day in Florida history was 109∘F, which occurred on June 29, 1931 in Monticello.

Hence, Put F=109∘ in 5/9(F−32)

then we get,

⇒5/9(F−32)

=5/9(109−32)

​Now, apply PEDMAS rule then we get,

=5/9(109−32)

=5/9(77)

=0.5555(77)

=42.7777

≈42.8∘

C (Rounding off to the nearest tenth)

​Thus, the temperature in degrees Celsius is 42.8∘C

Question. The coldest recorded day in Florida history was about -18.°C, which occurred on February 13m 1899 in the city of Tallahassee. Convert this temperature to degrees Fahrenheit. Round  your answer to the nearest tenth of a degree.

Given: The coldest recorded day in Florida history was about −18.9∘C, which occurred on February 13, 1899 in the city of Tallahassee.

To Determine: Convert this temperature to degrees Fahrenheit. Round your answer to the nearest tenth of a degree.

For converting this temperature to degrees Fahrenheit we use 9/5c+32

It is given that the coldest recorded day in Florida history was about −18.9∘C, which occurred on February 13,1899 in the city of Tallahassee.

Hence,put c=−18.9∘C in 9/5c+32 then we get,

⇒9/5c+32

=9/5(−18.9)+32

​Now, apply BODMAS rule then we get,

=9/5(−18.9)+32

9/5(−18.9)+32 =1.8(−18.9)+32

9/5(−18.9)+32 =−34.02+32

9/5(−18.9)+32 =−2.02

9/5(−18.9)+32 ≈−2∘F

​Thus, the temperature in degrees Fahrenheit is −2∘F

Given: The balance in Mr. Sanchez′s bank account was $293.74 and he accidentally wrote a check for $300.

To find His balance now.

Subtract the check  Mr. Sanchez  accidentaly wrote from his balance bank account.

When the amount that is subtracted is greater than the amount from which it is subtracted, then you can subtract the smaller amount from the larger amount and put the negative sign in the result.

Mr. Sanchez’s bank account balance is $293.74.

He wrote a check of $300.

The new balance will be the difference of the starting balance minus the amount of the chek:

So, his new balance is: 293.74−300=−6.96.

Therefore, the balance amount in Mr. Sanchez’s bank account after the accicentally wrote a check for $300

when the balance of his bank account was $293.74 is −$6.26.

Step-By-Step Answers For Exercise 1.1 Chapter 1 In Holt Algebra 1 Homework And Practice Workbook Page 1 Problem 13 Answer

Given: Paula always withdraws 20 dollars more than she needs from the bank.

To Find: The amount of money Paula withdraws if she needs 20,60, and 75 dollars.

For finding the amount of money Paula withdraws if she needs 20,60, and 75 dollars we have to put 20,60, and 75 dollars in w=d+20

From first part we have w=d+20

Now,

for d=20

we get,

w=d+20

∴w=20+20

∴w=40

for d=60

we get,

w=d+20

∴w=60+20

∴w=80

​for d=75

we get,

w=d+20

∴w=75+20

∴w=95

​Thus, the amount of money Paula withdraws if she needs 20,60, and 75 dollars are 40,80 and 95 respectively.

Given: Anna called two people and asked each of them to call two other people, and so on.

It takes one minute to call two people.

To Find: How many phone calls were made during the fifth minute?

Method Used: From left to right, evaluate all powers.

To raise a number to a power, simply multiply it by itself that many times.

We know, Anna called two people and asked each of them to call two other people, and so on.

It take one minute to call two people.

In the first minute, anna calls two people, that means 21.

In the second minute, each of two people calls 2 people, that means 2².

Similarly, In the third minute, number of calls =2³.

Similarly, In the fourth minute, number of calls =2⁴.

So, in the fifth minute, the number of calls =2⁵

Simplify,

2⁵=2×2×2×2×2

2⁵=32.

Therefore, the number of calls made during fifth minute is 32.

Exercise 2.7 Solutions For Chapter 2 Holt Algebra 1 Homework And Practice Workbook Page 15 Problem 4 Answer

Given: Radius of cylinder=3cm

Length of cylinder=10cm

and every dimension of cylinder is multiplied by 3 to form a new cylinder.

To find the ratio of the volumes related to the ratio of corresponding dimension

We find the new dimension and using that we find new volume and proceed.

Original radius=3cm;Length=10cm

New Radius =3× 3 cm =9cm

new length = 10× 3 = 30cm

we know Volume of cylinder = 2πrh²

Therefore, ratio of volume=  2π(3)²(10)²π(9)²(30)=1/27=1/3³

Hence the ratio of volume is 3 times the ratio of dimension

Hence the ratio of volume is 32 times the ratio of dimension
