At 2:30 am the temperature in Joelle is 3 F. The temperature drops 3/4 of a degree in 30 min. What is the temperature on Joelle at 3:00am?
Answer: B. [tex]=2.25^{\circ}F[/tex]
Step-by-step explanation:
Given: At 2:30 am the temperature in Joelle is 3 F.
The temperature drops 3/4 of a degree in 30 min.
3/4 of a degree= [tex]\frac{3}{4}\times1^{\circ}F=\frac{3}{4}=0.75^{\circ}F[/tex]
Therefore, the temperature on Joelle after 30 min= [tex]3^{\circ}F-\frac{3}{4}\ of\ 1^{\circ}F[/tex]
[tex]=3^{\circ}F-0.75^{\circ}F[/tex]
[tex]=2.25^{\circ}F[/tex]
Thus, the temperature on Joelle at 3:00am=[tex]=2.25^{\circ}F[/tex]

Marcus sorts his 85 baseballs cards into stacks of 9 cards each. How many stacks of 9 cards Marcus make
Marcus can make 9 full stacks.
To determine how many stacks Marcus can make, we need to perform a division of the total number of baseball cards by the number of cards per stack.
Total number of baseball cards: 85.
85 ÷ 9.
= 9 (with a remainder of 4.)
This means Marcus can make 9 full stacks of 9 cards each with 4 cards left over.

Write the point-slope form of the equation of the line that passes through the points (-3, 5) and (-1, 4). Include your work in your final answer.
Answer:
y-5=-1/2(x+3)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-5)/(-1-(-3))
m=-1/(-1+3)
m=-1/2
y-y1=m(x-x1)
y-5=-1/2(x-(-3))
y-5=-1/2(x+3)
The shelf is made of 3 pieces of wood, each 0.3 meter wide. There is also 0.05 meter of space between the shelf and the wall on each side. What is the width, in meters, of the closet?
A. 0.4
B. 0.8
C. 1
D. 1.9
The correct answer is: C: 1 meter. The closet width is 1 meter, including the contribution from the three pieces of wood and the spaces on each side.
To determine the width of the closet, we need to add up the widths of the three pieces of wood and the spaces on each side.
Given:
- Width of each piece of wood: 0.3 meters
- Number of pieces of wood: 3
- Space on each side between the shelf and the wall: 0.05 meters
Now, calculate the total width:
[tex]\[ \text{Total Width} = (\text{Width of one piece of wood} \times \text{Number of pieces of wood}) + (\text{Space on one side} \times 2) \][/tex]
[tex]\[ \text{Total Width} = (0.3 \times 3) + (0.05 \times 2) \][/tex]
[tex]\[ \text{Total Width} = 0.9 + 0.1 \][/tex]
[tex]\[ \text{Total Width} = 1 \, \text{meter} \][/tex]
The width of the closet is 1 meter, considering the combined width of the three pieces of wood and the spaces on each side.
Therefore, the correct answer is: C: 1 meter. The closet width is 1 meter, including the contribution from the three pieces of wood and the spaces on each side.

Melanie prepared 7 1/2 tablespoons of her spice mixture she is 1/4 tablespoon to make a batch of barbecue sauce estimate the number of batches of barbecue sauce she can make by using the spice mixture
Answer: There are 30 batches of barbeque sauce that she can make by using the spice mixture.
Step-by-step explanation:
Since we have given that
Number of tablespoons of her spice mixture = [tex]7\dfrac{1}{2}=\dfrac{15}{2}[/tex]
Number of tablespoons to make a batch of barbeque sauce = [tex]\dfrac{1}{4}[/tex]
so, the number of batches of barbeque sauce would be
[tex]\dfrac{15}{2}\div \dfrac{1}{4}\\\\=\dfrac{15}{2}\times 4\\\\=15\times 2\\\\=30[/tex]
Hence, there are 30 batches of barbeque sauce that she can make by using the spice mixture.

OF bisects EOF. EOF=y+30 and FOG=3y-50. solve for y.
Setting the given equations equal to each other, we can solve for y and determine that y equals 40.
Explanation:The question states that OF bisects EOF, which means that EOF and FOG are equal. Hence, you can set the two equations equal to each other to solve for y.
EOF = y + 30FOG = 3y - 50Set EOF equal to FOG:
y + 30 = 3y - 50
To solve for y, first simplify the equation by subtracting y from both sides:
30 = 2y - 50
Then add 50 to both sides to isolate the y variable on one side:
80 = 2y
Finally, divide both sides by 2 to solve for y:
y = 40

Round 0.955 inches to the nearest tenth of an inch
The nearest tenth is the first digit after the decimal point. The round 0.955 inches to the nearest tenth of an inch is 1.0 inches.
Given 0.995 inches
round to the nearest tenth of an inch.
This means round to the nearest first decimal point and to include the actual first decimal point (and that decimal point only, the tenth place).
We are given the number 0.955. This is given to the nearest thousands.
We examine the tenth place at 0.9.
So we know our choices are
What is the nearest tenth?The nearest tenth is the first digit after the decimal point.
0.9 (round down to the nearest tenths place) or 1.0 (round up to the nearest tenths place).
We examine the number 0.955 and look to the next value, the hundredths place
If that digit is 5 or greater we round up and the correct answer is 1.0.
If that number is 4 or less (i.e. 0 to 4), we round down and the correct answer is 0.9.
In the case of our give value: 0.955.
The digit to the right of 9 is 5 so, as previously mentioned,
we round up to 1.0.
Therefore, The round 0.955 inches to the nearest tenth of an inch is 1.0 inches.
The answer is 1.0 inches.
