Jenna has a spool that contains 5 and 3/4 meters of ribbon. She uses 3 and 2/4 meters for a school project and 1 and 1/4 meters for a bow. How much ribbon remains on the spool?
Answer:
It will be 1 0/4
Step-by-step explanation:
The 4 stays the same because its the denominater.
After using some of her ribbon for a project and a bow, Jenna has 1 meter of ribbon left on the spool.
Jenna has a spool that contains 5 and 3/4 meters of ribbon. She uses 3 and 2/4 meters for a school project and 1 and 1/4 meters for a bow. To find out how much ribbon remains on the spool, we need to subtract the total amount of ribbon used from the initial amount.
First, let's simplify the fractions. 3 and 2/4 meters can be simplified to 3 and 1/2 meters because 2/4 is equivalent to 1/2.
Next, we add the lengths of ribbon used for the project and the bow together: 3 and 1/2 meters + 1 and 1/4 meters = 4 and 3/4 meters.
Finally, we subtract this amount from the total amount of ribbon Jenna had: 5 and 3/4 meters - 4 and 3/4 meters = 1 meter.
Therefore, after using ribbon for a school project and a bow, Jenna has 1 meter of ribbon left on the spool.
The Strike Zone Battling Center provides cages for baseball players to perfect their swing. The patron pays a fixed rate of $12.75 for the first 45 minutes, pay an additional $0.35 for up to two hours and $0.25 per minute for any additional time over two hours. The following function is used to compute the overall cost for a patron.
where x is the amount of time in minutes spent battling at the Strike Zone. How much would you pay for 115 minutes?
To calculate the cost for 115 minutes at the Strike Zone Battling Center, we account for the flat rate for the first 45 minutes and add the additional cost for the remaining 70 minutes at a rate of $0.35 per minute. We find that the total would be $37.25.
Explanation:The cost calculation for using the cages at the Strike Zone Battling Center operates on a tier system. The first 45 minutes costs a flat rate of $12.75. If a patron uses it for additional time up to 2 hours (or 120 minutes), it's an extra $0.35 per minute. Anything over 2 hours is $0.25 per minute.
To calculate the cost for 115 minutes, we determine that it is less than 2 hours. Therefore, the cost will be the flat rate of $12.75 plus the additional cost for 70 minutes (which is 115 minutes minus the first 45 minutes) at $0.35.
The calculation goes as follows:
$12.75 + (70 * $0.35) = $12.75 + $24.50 = $37.25.
So, for 115 minutes, you would pay $37.25

What did you have to multiply the first equation by, if anything?
What did you have to multiply the second equation by, if anything?
Answer:
cils Gabby bought a nens and Spencils
6 bills in the deposit were $10 bills.
Step-by-step explanation:
The total number of bills he gave the teller = 24 bills
x + y = 24 ------------(1)
Let,
x be the number of $5 bills.
y be the number of $10 bills.
The total bank deposit made using $5 and $10 bills are $150.
He deposits $5 bills and $10 bills. So, the equation can be framed as :
5x + 10y = 150 --------(2)
The question is asked for how many $10 bills were in the deposit,
Here 'y' is the number of $10 bills.
To solve for y value :
The eq(1) must be multiplied by 5 and subtract eq(2) from eq(1),
5x + 5y = 120
-(5x + 10y = 150)
-5y = -30
⇒ y = 30/5
⇒ y = 6
Therefore, there were 6 bills in the deposit that are $10 bills.

What value does the red dot represent on the number line?
The red dot on the number line represents the value [tex]\(\frac{4}{5}\)[/tex], corresponding to option C.
In a fraction, the numerator (4) denotes the number of parts considered, while the denominator (5) indicates the total number of equal parts in one whole.
Thus, [tex]\(\frac{4}{5}\)[/tex] signifies four parts out of five, placing the red dot closer to the whole number 1 but not reaching it.
This representation aligns with the fraction's numerical value, emphasizing the position of the red dot on the number line and its fractional significance in relation to the unit interval.
Hence, the correct answer is Option C. 4/5
Determining the value of the red dot requires analyzing its position on the number line relative to specific landmarks and measurements provided; however, without the visual of the number line, a precise answer cannot be given.
Explanation:The value of the red dot on the number line can be determined based on its position relative to the given reference points. The various descriptions of dots' positions involve a comparison to Car X and Car Y figures, as well as precise measurements in terms of perpendicular hash marks on a graph. To ascertain the value that the red dot represents, we must closely examine its placement on the number line in comparison to these references. However, it's crucial to have a visual representation of the number line to provide an accurate value. The mentioned descriptions such as 'the third dot is about one and two-thirds perpendicular hash marks to the right of the center top perpendicular hash mark' indicate the need to understand measuring units and relative positioning on the number line.
An art exhibit is made by stacking three identical prisms on top of each other end-to-end so their smallest faces overlap. One of the prisms is shown here.
Find the surface area of the total exhibit.
The surface area of the exhibit is 1,638 cubic inches.
Step-by-step explanation:
Step 1:
If three prisms are out on top of each other we get a shape as follows;
The length of the base [tex]= 9[/tex] inches,
The width of the base [tex]=6[/tex] inches, and
The height of the exhibit [tex]= 3(17) = 51[/tex] inches.
To find the surface area of the total exhibit we consider there to be only one shape which the above dimension.
Step 2:
There are 6 faces to the exhibit.
The surface area of a rectangular prism is given by;
[tex]A=2(w l+h l+h w)[/tex]
By substituting the values, we get
[tex]A=2((6)(9)+(51) (9)+(51) (6)) = 2 (819) = 1,638.[/tex]
The surface area of the exhibit is 1,638 cubic inches.

The area of the given figure 156.75 sq cm.
Step-by-step explanation:
Here,
The figure is a trapezium.
In this trapezium
a = 22 cm
b = 6.5 cm
A and b are the length of two parallel sides.
Height (h) = 5.5 cm
To find the area of the figure which is consists of two trapezium
Formula
Area of the trapezium = [tex]\frac{1}{2} (a+b)h[/tex]
Now,
The area of one trapezium = [tex]\frac{1}{2} (22+6.5)X5.5[/tex] sq cm
= 78.375 sq cm
So,
The area of the figure = 78.375×2 sq cm = 156.75 sq cm

a^2-a+12
a^2-a-12
-a^2-a-12
-a^2-a+12
Answer:
-a^2 + -a + 12
Step-by-step explanation:
Expand the following:
(3 - a) (a + 4)
(3 - a) (a + 4) = (3) (a) + (3) (4) + (-a) (a) + (-a) (4):
-a a + 3 a - 4 a + 3 4
3×4 = 12:
-a a + 3 a - 4 a + 12
-a a = -a^2:
-a^2 + 3 a - 4 a + 12
Grouping like terms, -a^2 + 3 a + 4 (-1) a + 12 = -a^2 + (3 a - 4 a) + 12:
-a^2 + (3 a - 4 a) + 12
3 a - 4 a = -a:
Answer: -a^2 + -a + 12

Answer:
The radius is 2.5 yards
The diameter is 5 yards
Step-by-step explanation:
We want to find the radius and diameter given that, the circumference of the circle is;
C=5π yards.
Recall that, the circumference of a circle is C=πd
This implies that:
[tex]5\pi = \pi \: d[/tex]
Divide both sides by π
[tex]5 = d[/tex]
To find the radius, divide the diameter by 2;
[tex]r = \frac{5}{2} = 2.5[/tex]
The radius is 2.5 yards
The diameter is 5 yards
according to a recipe, 9/20 oz, of sugar is needed to make 6 cookies. Ashley decided to use only a third of the sugar to make it healthier. how much sugar did Ashley use?
Answer:
The amount of sugar actually used by Ashley to bake 6 cookies is 0.15 oz
Step-by-step explanation:
The amount of sugar needed to make 6 cookies = (9/20) oz
So, the total amount of sugar to be used = (9/20) oz
Let us assume the sugar actually used by Ashley = M oz
Also, given:
Sugar Used = One third of SUGAR NEEDED
[tex]\implies M = (\frac{1}{3}) \times (\frac{9}{20})[/tex]
= [tex](\frac{3}{20} )[/tex] = 0.15 oz
or M = 0.15 oz
Hence, the amount of sugar actually used by Ashley to bake 6 cookies is 0.15 oz.
