triston is baking specity bread for the school bake sale. she has 10 1/2 cups of flour. the recipe for 1 loaf of bread calls for 2 1/3 cups of flour. How many whole loaves of bread can she make.

Answers

Triston can make a total of 4 loafs

Triston can make 4 whole loaves of bread using her 10 1/2 cups of flour. This was determined by dividing the total flour available by the flour required per loaf. Fractional or partial loaves are not counted.

To determine how many whole loaves of bread Triston can make, we need to perform a simple division of the total amount of flour by the amount required for one loaf.

First, let's convert the mixed numbers to improper fractions:

10 1/2 cups of flour = 21/2 cups of flour2 1/3 cups of flour = 7/3 cups of flour

Next, we will divide the total flour by the flour needed per loaf:

(21/2) ÷ (7/3) = (21/2) × (3/7) = (21 × 3) / (2 × 7) = 63/14 = 4.5 loaves

Since we can only make whole loaves, Triston can make 4 whole loaves of bread.

A piggy bank contains the same number of quarters, nickels, and dimes. the coins total $4.40. how many of each type of coin does the piggy bank contain?

Answers

Let the number of each coin be n.

The total sum of these coins is $4.40. So we can write:

n Nickles + n Dimes + n Quarters = 4.40

0.05n + 0.10n + 0.25n = 4.40

0.40n = 4.40

n = 11

So this means, there are 11 coins of each type.

Answer: 11 of each type

Answers

This week: 4+3+3 = 10
Last week: 8

Sarah walked two more miles this week than last week.

Answer:

2 miles

Step-by-step explanation:

Sara loves to go hiking.

She hiked 3 miles on Monday 4 miles on Tuesdays and 3 miles on Thursday.

Last week Sara hiked 8 miles

This week sara hiked = Monday + Tuesday + Thursday

= 3 + 4 + 3

= 10 miles

Last week hiked = 8 miles

Difference in two week hiked by Sarah = 10 - 8

= 2 miles

So, Sarah hike 2 miles more than last week.

If one line on top of the other then Infinitely many solutions.

If the lines are parallel then No solution.

Answer:

D. Infinitely many solutions

Step-by-step explanation:

We have been given an image of two lines on coordinate plane. We are asked to find the number of solutions for our given lines.

Upon looking at our given graph, we can see that both lines are same. Since both lines coincide, therefore, each point on the line will be solution of our given lines.

Therefore, our given lines will have infinitely many solutions and option D is the correct choice.

Monica had $42 and Naomi had $18 at first. Monica then gave $6 to Naomi. What is the ratio of the amount of money Monica has to the amount of money Naomi has in the end?

Answers

1) 6:3
2) 11:3
3) 15:16
4) 3:2

Final answer:

To find the ratio of the number of apples to the total number of fruits, divide the number of apples by the total number of fruits. Simplify the ratio by dividing both numbers by their greatest common factor. For the ratio of chicken filets to fish filets, divide the number of chicken filets by the total number of filets. Simplify the ratio if possible. To find the ratio of boys to girls, determine the new number of boys and girls after some changes. For the ratio of money, calculate the amounts each person has and simplify the ratio.

Explanation:

To find the ratio of the number of apples to the total number of fruits, we divide the number of apples (24) by the total number of fruits (24 apples + 18 oranges = 42). This gives us a ratio of 24:42. We can simplify this ratio by dividing both numbers by their greatest common factor, which is 6. So the simplified ratio is 4:7.

For the second question, we need to find the ratio of the number of chicken filets to the number of fish filets. There are 12 chicken filets and a total of 44 filets in the freezer. So the ratio is 12:44. This can also be simplified by dividing both numbers by 4, giving us a simplified ratio of 3:11.

In the third question, we start with 12 boys and 18 girls. Then, 3 more boys join and 2 girls leave. So the new number of boys is 12 + 3 = 15, and the new number of girls is 18 - 2 = 16. The ratio of boys to girls is therefore 15:16.

In the fourth question, Monica has $42 and Naomi has $18. When Monica gives $6 to Naomi, Monica will have $42 - $6 = $36 left, and Naomi will have $18 + $6 = $24. The ratio of the amount of money Monica has to the amount of money Naomi has is 36:24, which can be simplified to 3:2.

What is the surface area of the prism? Include steps.

Answers

First things first. This is a rectangular prism, so it's faces are all rectangles.

Area of a rectangle: Area = Length x Height

- Rectangular Prism Dimensions:

Length: 3m
Width: 4m
Height: 2m

To calculate the surface area of a rectangular prism we first need to realize that he has 3 pairs of equal rectangles.

- The first pair (Photo 1):

Two rectangles with the same measure, so we can say that the area of this pair is: (L x H) x (L x H) or 2 x (L x H).

-> Area (Pair 1) = 2 x (3 x 2) = 2 x 6 = 12m^2

But if we will do the same thing to 3 different pairs, we can describe that:

- Total Surface Area (At):

At = 2 x (L x H) + 2 x (L x H) + 2 x (L x H)

-> At = 2 x ((L x H) + (L x H) + (L x H))

So now, just put the values inside de formula,

- Pair 1: Length = 3m ; Height = 2m

- Pair 2: Length = 4m ; Height = 2m

- Pair 3: Length = 4m ; Height = 3m

*I know that this pair doesn't have a "real Height" but this doesn't change anything when solving, you can consider the 4m as height and the 3m as length or vice versa, the order of the factors doesn't change the product.

-> At = 2 x ((3 x 2) + (4 x 2) + (4 x 3))
-> At = 2 x (6 + 8 + 12)
-> At = 2 x (26)

-> At = 52 m^2

Use double angle to rewrite 12sinxcosx

Answers

Final answer:

To rewrite 12sinxcosx using the double angle formula, multiply by (1/2) and use the formula for sin(2x) to obtain the answer of 12sin(2x).

Explanation:

To rewrite 12sin(x)cos(x) using the double angle formula, we need to know the formula for sin(2x) and cos(2x). The double angle formula for sine is sin(2x) = 2sin(x)cos(x), and for cosine it is cos(2x) = cos^2(x) - sin^2(x). Let's use these formulas to rewrite the expression:

12sin(x)cos(x) = 12 * (1/2) * 2sin(x)cos(x), since 1/2 is the value of cos^2(x) - sin^2(x).12 * (1/2) * 2sin(x)cos(x) = 6 * 2sin(x)cos(x).6 * 2sin(x)cos(x) = 12sin(2x). This is our final answer, using the double angle formula to rewrite the original expression.

A bus covered the 400-km distance between points a and b at a certain speed. on the way back the bus traveled at the same speed for 2 hours and then increased the speed by 10 km/hour until it reached a, thus spending 20 fewer minutes on the return trip. how long did the return trip take?

Answers

Let the speed going to B be x, the time taken be t and distance is 400 km
xt=400,
On the way back, the 2x+(x+10)(t-7/3), where it was total time minus 2 hours already driven minus 1/3 of hour, the 20 minutes.
2x+xt-(7/3)x+10t-70/3=400
2x+400-(7/3)x+10t-70/3=400
thus
-(1/3)x+4000/x=70/3
multiplying through by x we get:
-(1/3)x^2-(70/3)x+4000=0
x^2+70x-12000=0
x=(1/2)(-70+/-sqrt52900)
x=80 kmp
thus:
it took 5 hours to make the first trip
on way back 2 hours at 80 kph which means he traveled for 160 km at this speed
2 h 40 min at 90 k/h=90*8/3=240 km

The speed going to B is x, the time t and the distance, 400 km.

xt=400, x kph and t in hours

on the way back, the 2x+(x+10)(t-7/3), where it was total time minus 2 hours already driven minus 1/3 of an hour, the 20 minutes.

2x+xt-(7/3)x+10t-70/3=400

2x+400-(7/3)x+10t-70/3=400, 400 cancels, t=400/x

-(1/3)x+4000/x=70/3

multiply by x

-(1/3)x^2-(70/3)x+4000=0

x^2+70x-12000=0

x=(1/2)(-70+/- sqrt 52900); sqrt term=230

x=80 kph

took 5 hours to go there

on way back 2 hours at 80 kph=160 km

2h40m at 90kph=90*8/3=240 km

They add to 400 km.

The return trip took 4h40m
