the student council orders 12 sandwhiches for the school dance. each sandwich is 6 feet long cut into sections that are 4 inches long. how many small sandwiches will they have?
1ft = 12inch​

Answers

Answer 1

The school council will have 216 small sandwiches.

Step-by-step explanation:

Sandwiches ordered = 12

Length of one sandwich = 6 feet

1 foot = 12 inch

6 feet = 12*6 = 72 inches

Length of one sandwich in inches = 72 inches

As one small sandwich is 4 inches,

Number of small sandwiches in one sandwich = [tex]\frac{72}{4}=18[/tex]

One sandwich = 18 small sandwiches

12 sandwiches = 18*12 = 216 small sandwiches

The school council will have 216 small sandwiches.

A birdhouse has a shadow that is 12 feet long.

Jin is 5 feet tall, and he is standing next to the birdhouse.
Jin has a shadow that is 3 feet long. What is the height of the birdhouse in feet ?

Answers

Answer: 5 feet tall

Step-by-step explanation:

because he is beside the bird house he is 5 feet tall

The birdhouse's height is 20 feet, calculated using the proportion: [tex]\( \frac{h}{12} = \frac{5}{3} \).[/tex]

We can solve this problem using proportions.

Let [tex]\( h \)[/tex] be the height of the birdhouse.

According to the given information, the ratio of Jin's height to his shadow length is the same as the ratio of the birdhouse's height to its shadow length:

[tex]\[ \frac{h}{12} = \frac{5}{3} \][/tex]

Now, cross-multiply to solve for [tex]\( h \):[/tex]

[tex]\[ 3h = 5 \times 12 \][/tex]

[tex]\[ 3h = 60 \][/tex]

[tex]\[ h = \frac{60}{3} \][/tex]

[tex]\[ h = 20 \][/tex]

So, the height of the birdhouse is 20 feet.

Petra was given 12 yards of fabric to make costumes for the school play if each costume requires 1 1/2 yards how many costumes can she make

Answers

Petra can make 8 costumes with 12 yards of fabric

Solution:

Given that Petra was given 12 yards of fabric to make costumes for the school play

Each costume requires [tex]1\frac{1}{2}[/tex] yards

To find: number of costume Petra can make

The number of costume Petra can make is calculated by dividing the total fabric she has by fabric needed for one costume

[tex]\text {number of costume Petra can make }=\frac{\text {total fabric she has }}{\text {fabric needed for one costume }}[/tex]

Total fabric she has = 12 yards

Fabric needed for 1 costume = [tex]1\frac{1}{2} = \frac{2 \times 1 + 1}{2} = \frac{3}{2}[/tex] yards

Therefore,

[tex]\text {number of costume Petra can make }=\frac{12}{3 / 2}=\frac{12}{3} \times 2=8[/tex]

Thus petra can make 8 costumes with 12 yards of fabric

A group of mountain climbers begin a expedition with 250 pounds of food. They plan to eat a total of 12 pounds of food per day . Write and solve a linear equation to find the number of days their food will last

Answers

Answer:

The equation representing total food consumption in [tex]x[/tex] days can be given as:

[tex]y=12x[/tex]

where [tex]y[/tex] represents total food taken which is =250 pounds and [tex]x[/tex] represnts the number of days the food will last.

The food will last for [tex]20\frac{5}{6}[/tex] days.

Step-by-step explanation:

Total pounds of food taken at the beginning =  250 pounds

Food consumed per day = 12 pounds

Let the total food at the beginning be = [tex]y[/tex] pounds

Let number of days the food will last be = [tex]x[/tex] days

Using unitary method to find the food consumed in [tex]x[/tex] days.

If in 1 day food consumed = 12 pounds

Then, in [tex]x[/tex] days food consumption = [tex]12\times x = 12x[/tex] pounds

So,the equation representing total food consumption in [tex]x[/tex] days can be given as:

[tex]y=12x[/tex]

Total food taken =250 pounds

Plugging in [tex]y=250[/tex] in the equation:

[tex]250=12x[/tex]

Solving for  [tex]x[/tex]

Dividing both sides by 12.

[tex]\frac{250}{12}=\frac{12x}{12}[/tex]

[tex]\frac{250}{12}=x[/tex]

Simplifying fractions.

[tex]\frac{125}{6}=x[/tex]

Converting fraction to mixed number by writing quotient as whole number, remainder as numerator and divisor as denominator.

∴ [tex]x=20\frac{5}{6}[/tex] days.

Thus, the food will last for [tex]20\frac{5}{6}[/tex] days.


[tex]2x + 5y = 25 \\ 3x - 2y = 9[/tex]
A) How to solve it by elimination method.

B) by substitution method
C) graphical method ​

Answers

I will show you A and B, and give you a hint how to do C, since brainly doesn't provide C option.

A.

The elimination method is how I would solve this system

[tex]

\begin{cases}

2x+5y=25 \\

3x-2y=9

\end{cases}

[/tex]

We start by multiplying the first equation by 3 and second by -2 to obtain

[tex]

\begin{cases}

6x+15y=75 \\

-6x+4y=-18

\end{cases}

[/tex]

Now add the two equations and thus eliminate the x-terms to obtain

[tex]19y=57\Longrightarrow y=\dfrac{57}{19}=3[/tex]

Then we insert the y into either of the original equations and solve for x

[tex]

2x+5\cdot3=25 \\

2x=25-15 \\

2x=10 \\

x=5

[/tex]

And we have the solution at [tex]P(5,3)[/tex].

B.

We pick one equation and express x

[tex]

2x+5y=25 \\

2x=25-5y \\

x=\dfrac{25-5y}{2}

[/tex]

Then we replace the x in other equation with expression we just calculated and solve for y

[tex]

3\cdot\dfrac{25-5y}{2}-2y=9 \\

\dfrac{75-15y}{2}-2y=9 \\

\dfrac{75-15y-4y}{2}=9 \\

75-19y=18 \\

-19y=-57 \\

y=3

[/tex]

Now we put y in either of the original equations to get x

[tex]

2x+5\cdot3=25 \\

2x=25-15 \\

2x=10 \\

x=5 \\

[/tex]

And again we get the solution [tex]P(5,3)[/tex].

C.

To find solution graphically, you need to put both lines in general form [tex]f(x)=mx+n[/tex] where [tex]f(x)=y[/tex]

[tex]

\begin{cases}

2x+5y=25\Longrightarrow y=\frac{25-2x}{5}=-\frac{2}{5}x+5 \\

3x-2y=9\Longrightarrow y=-\frac{9-3x}{2}=-\frac{3}{2}x-\frac{9}{2}

\end{cases}

[/tex]

Then plot the lines on the graph. The solution will be point [tex]P(5,3)[/tex] where lines intersect, because we can represent lines as sets of points ordered pairs. Consider our two lines represented as two functions g and f where

[tex]

f(x)=-\frac{2}{5}x+5 \\

g(x)=-\frac{3}{2}x-\frac{9}{2}

[/tex]

Graphs (sets) of these two functions are defined as (assuming [tex]f,g:D_f,D_g\to T_f,T_g=\mathbb{R}\to\mathbb{R}[/tex] since not specified):

[tex]

\displaystyle

G_f=\{(x,f(x)):x\in D_f\wedge f(x)\in T_f\} \\

G_g=\{(x,g(x)):x\in D_g\wedge g(x)\in T_g\}

[/tex]

Where D is definition zone (set of all x defined for function f or g) and T transformation zone (set of all f(x) or g(x)). Note that in our case [tex]D_f,T_f=D_g,T_g[/tex] because [tex]D_f,T_f,D_g,T_g=\mathbb{R}[/tex]

The solution is is intersection of these two sets

[tex]G_f\cap G_g=(5,3)[/tex]

x = 45/3

x = 15

The ages are 14,15,16

Answer:

Step-by-step explanation:

consecutive integers means 1 right after the other....with x being the youngest, then x + 1 being the second friend, and x + 2 being the third friend.

What is a better buy? Store A: $1.50 for 5 oz or Store B: $1.20 for 3 oz
And please explain, I really need help!

Answers

Store A would be better because ultimately, you get more for less. If you wanted 5 oz from Store B, it would be $2.00 ( 1.20/3 = 0.4. 0.4 x 5 = 2 ), which is more than Store A.

Answer:

Store A is the better buy.

Step-by-step explanation:

The first thing I did was to find a multiple that 3 and 5 share which is 15. Now, we can figure out how much each store charges for 15 oz. I put the numbers into fraction form to make it easier. 5/1.50 and 3/1.20. To get 5 to 15, I multiplied it by 3, so I also have to do that to 1.50. This leaves me with 4.50. Store A charges 4.50 for 15 oz. Next, we have to go over to the other fraction. To get 3 to 15, I multiplied it by 5. Whatever you do to the numerator, you have to do to the denominator, so you multiply 1.20 by 5. This gets you 6. Store B charges 6 dollars for 15oz, so store A has a better price. I hope this helps.

Write the numbers in order from greatest to least. 7.982, 7.981, 8.782, 8.981

Answers

Answer:

8.981, 8.782, 7.982, 7.981.

Step-by-step explanation:

To order decimals is to subtract, line up, and comparing digits.

Comparing digits is a good way to order decimals for greatest to least.

(Most Understood.)

Comparing Decimals:

We could put numbers in any order to compare digits, but you should look closely:

Numbers can Trick You.Be wise, look closely.If the digit is 0 for a number, the other number is greater if it's not 0.Lastly, you (cannot) multiply, divide, add, or subtract.

__________________________________________

First, we pick 2 numbers to compare, maybe 8.782 and 8.981.

We look at the digits for both numbers.

We see 8's, And 7 and 9, 9 is greater, so 8.981 is the greatest and 8.782 is the 2nd greatest.

8.981, 8.782, ?.???, ?.??? Is Our Order so far.

Our last 2 numbers are 7.981 and 7.982,

We look at the digits for both numbers.

We see 7's, we see 9's, and we see 8's, but 1 and 2. 2 is greater so 7.982 is the 3rd greatest and 7.981 is the least.

Our order is: 8.981, 8.782, 7.982, 7.981.We checked it by comparing wisely. (√ Means Check)

Best of Luck to you.

If you have any questions, feel free to comment below.

-Also if anything is confusing!!

Final answer:

The numbers 8.981, 8.782, 7.982, and 7.981 are ordered from greatest to least. This is determined by comparing each digit from left to right, where 8.981 is the greatest and 7.981 is the least.

Explanation:

The task that you are asked to do is to arrange the numbers from greatest to least. The numbers given are 7.982, 7.981, 8.782, and 8.981.

8.9818.7827.9827.981

This order is determined by comparing the digits from left to right. The first digit is the most significant indicator of the size of the number. However, if the first digits are the same, then we consider the following digits and so on until we find one that differs. In our case, 8.981 has both the largest initial digit (8) and the largest subsequent digits (9 and 8 respectively) so it is the greatest. Similarly, 7.981 has the smallest digits and as a result, it's the least.

You can see in the two tables the y-coordinates are the same value of [tex]4[/tex] when [tex]x=-1[/tex]. So basically the common point in both tables is [tex](-1,4)[/tex] so [tex](-1,4)[/tex] is a solution.

Part C:

I'm going to graph both [tex]y=4^{-x}[/tex] and [tex]y=2^{x+3}[/tex] on the same coordinate plane. I will then find where they will intersect.

I'm going to graph my points from the table to [tex]y=4^{-x}[/tex] and [tex]y=2^{x+3}[/tex].

This can be seen in my drawing.

I graphed [tex]y=4^{-x}[/tex] in blue.

I graphed [tex]y=2^{x+3}[/tex] in red.

Another way:

An algebraic approach:

[tex]4^{-x}=2^{x+3}[/tex]

[tex](2^2)^{-x}=2^{x+3}[/tex] (since [tex]4=2^2[/tex] and now the bases on both side are the same)

[tex]2^{-2x}=2^{x+3}[/tex]

[tex]-2x=x+3[/tex] (since [tex]2^{a}=2^{b}[/tex] then [tex]a=b[/tex])

[tex]-3x=3[/tex] (subtracted [tex]x[/tex] on both sides)

[tex]x=-1[/tex] (divided both sides by [tex]-3[/tex])

The solution is [tex]x=-1[/tex].

Two cars leave towns
400

kilometers apart at the same time and travel toward each other. One car's rate is
12

kilometers per hour less than the other's. If they meet in
2

hours, what is the rate of the slower car?

Answers

The speed of slower car is 94 kilometers per hour.

Step-by-step explanation:

Given,

Total distance covered by both cars = 400 km

Time period = 2 hours

Let,

Speed of one car = x

Speed of slower car = x-12

Combined speed = [tex]x+(x-12)=x+x-12=2x-12[/tex]

Distance = Speed*Time

[tex]400=(2x-12)*2\\400=4x-24\\400+24=4x\\424=4x\\4x=424[/tex]

Dividing both sides by 4

[tex]\frac{4x}{4}=\frac{424}{4}\\x=106[/tex]

Speed of slower car = x-12 = 106-12 = 94 km/h

The speed of slower car is 94 kilometers per hour.
