at 2:30 a.m. the temperature in joelle is – 3f. the temperature drops 3/4 of a degree in 30 minutes. what is the temperature in joelle at 3:00 a.m.?

Answer:

t = 1/2

Step-by-step explanation:

4(t+1/4)=3

First, distribute:

4(t)+4(1/4)=3

4t+1=3

Then isolate the variable:

4t+1-1=3-1

4t=2

4t/4=2/4

t=2/4

t=1/2

The equation is solved first by distributing the 4, then by subtracting 1 from both sides to isolate the variable term, and finally by dividing both sides by 4 to solve for 't', which gives the solution t = 0.5.

To solve the equation 4(t+1/4) = 3, we start by distributing the 4 inside the parentheses, so we get 4t + 1 = 3.

Then, we subtract 1 from both sides of the equation to isolate the variable term, and this gives us 4t = 2.

Finally, to solve for 't', we divide both sides of the equation by 4, and we find that t = 0.5.

Answer:

The Area of rectangle A is  576 feet²  .

Step-by-step explanation:

Given as :

The width of rectangle A = 16 feet

The Length of rectangle A = 8 feet + The length of rectangle B

The width of rectangle B = 14 feet

Let The length of rectangle B = L feet

So, The Length of rectangle A = 8 feet + L feet

The perimeter of rectangle A + The perimeter of rectangle B = 156 feet

So, 2 × ( Length A + width A ) +  2 × ( Length B + width B ) = 156 feet

Or,  2 × ( 8 + L + 16 ) +  2 × ( L + 14 ) = 156 feet

Or,  2 ×( 24 + L ) +  2 × ( L + 14 ) = 156 feet

Or, 48 + 2 L + 2 L + 28 = 156

Or, 76 L + 4 L = 156

So, 4 L = 156 - 76

Or, 4 L = 80

∴  L = [tex]\frac{80}{4}[/tex] = 20 feet

So , The Length of rectangle A = 8 feet + 28 feet = 36 feet

And The width of rectangle A = 16 feet

So, Area of rectangle A = Length of rectangle A × width of rectangle A

I.e  Area of rectangle A = 36 × 16 = 576 feet²

Hence The Area of rectangle A is  576 feet²  . Answer

Answer:

0.5 891 7,800

Step-by-step explanation:

is because least always go first

To order from least to greatest, convert all measurements to grams: 7,800 mg becomes 7.8 g, and 0.5 kg becomes 500 g. The order is 7.8 g, 500 g, and 891 g.

To order the weights 891 g, 7,800 mg, and 0.5 kg from least to greatest, we first convert them all to the same unit. Given that there are 1,000 mg in a gram (g) and 1,000 g in a kilogram (kg), we can convert as follows:

Now that we have all the weights in grams, we can easily compare them:

Ordering these from least to greatest, we get: 7.8 g < 500 g < 891 g.

x=841/68

Step-by-step explanation:

-68(x-11)=1+(-94)

-68(x-11)=-93

-68x+748=-93

-68x=-93-748

-68x=-841

68x=841

x=841/68

Final answer:

To solve this problem, set up an equation by representing the unknown number as x. Distribute -68 to the terms inside the parentheses and solve for x by isolating it on one side of the equation.

Explanation:

To find the answer to this problem, we can set up an equation. Let's let the unknown number be represented by x. The difference between a number and 11 can be written as (x - 11). The problem states that -68 times this difference is equal to the number one plus -94, which can be written as -68(x - 11) = -94 + 1.

To solve this equation, we can distribute -68 to the terms inside the parentheses: -68x + 748 = -93. Then, we can subtract 748 from both sides to get -68x = -841. Finally, we divide both sides by -68 to find that x = 12.38.

Therefore, the solution to this problem is x = 12.38.

a) The total amount the Bells will pay for their house is $187,488. b) The interest paid, including the 3 points, is $97,488. c) The exact amount applied to the principal in the first payment is unknown without additional information.

a) To determine the total amount the Bells will pay for their house, we need to calculate the total amount paid over 20 years. The monthly mortgage payment is $781.20, so the annual payment would be $781.20 x 12 = $9374.40. Therefore, over 20 years, the Bells will pay $9374.40 x 20 = $187,488.

b) The interest paid over the 20-year mortgage period can be calculated by subtracting the total mortgage amount from the total amount paid. The total mortgage amount is $90,000, so the interest paid is $187,488 - $90,000 = $97,488, including the 3 points.

c) The first payment on the mortgage is typically applied mostly to the interest. However, to determine the exact amount applied to the principal, we need more information about the breakdown of the monthly mortgage payment between interest and principal.

Step-by-step explanation:

Answer:

The number of once is 9.1  

The number of hundreds is 8.9

Step-by-step explanation:

Given as :

The total of digits having ones and hundreds = 900

The sum of digits = 18

Let The number of ones digit = O

And The number of hundreds digit = H

So, According to question

H + O = 18             .........1

100 × H + 1 × O = 900          ........2

Solving the equation

( 100 × H - H ) + ( O - O ) = 900 - 18

Or, 99 H + 0 = 882

Or , 99 H = 882

∴   H = [tex]\frac{882}{99}[/tex]

I.e H = 8.9

Put the value of H in eq 1

So, O = 18 - H

I.e  O = 18 - 8.9

∴    O = 9.1

So, number of once = 9.1

number of hundreds = 8.9

Hence The number of once is 9.1  and The number of hundreds is 8.9

Answer

Final answer:

The number that fits the criteria of rounding to 900, having twice as many hundreds as ones, having all different digits, and the sum of its digits being 18, is 864.

Explanation:

The question involves finding a number that meets a set of criteria: it rounds to 900, has twice as many hundreds as ones, all its digits are different, and the sum of its digits equals 18. To solve the problem, we can break down the clues and use them to narrow down the possibilities.

Since the number rounds to 900, we know it must be in the range of 850 to 949. The clue that it has twice as many hundreds as ones implies that the number of hundreds is a digit that is double the digit in the ones place. And since all digits must be different, we are looking for a number that does not repeat any digit.

Given the criteria, let's assume the hundreds digit is '8' (since it's in the 800 series), and therefore the ones digit would be '4'. The only digit left to assign is the tens place, which cannot be the same as the other two and must ensure the sum of all three digits equals 18. The digit for the tens place should then be 18 - 8 - 4 = 6, making the number 864, which satisfies all conditions.

So, the number we are looking for is 864: it rounds to 900, has twice as many hundreds (8 hundreds) as ones (4 ones), all digits are different, and the sum of the digits (8+6+4) equals 18.

Final answer:

To determine which negative number is greater between -4.03 and -4.3, compare their standard forms with the same exponent, concluding that -4.03 is larger due to its higher coefficient.

Explanation:

To determine which number is larger between -4.03 and -4.3, we can compare them in standard form:

-4.03 = -4.03 × 100

-4.3 = -4.3 × 100

Since both numbers have the same power of 10 (exponent), we compare the coefficient: -4.03 is larger than -4.3 because 0.03 is greater than 0. Therefore, -4.03 is larger than -4.3.
