Answer:

Rate: $32 per 4 shirts.

Unit rate: $8 per shirt.

Step-by-step explanation:

We have been given that 4 shirts for $32.00. We are asked to find the rate and unit rate for given situation.

The rate of the given scenario is $32 per 4 shirts.

To find the unit rate, we will divide total cost by number of shirts as:

[tex]\text{Unit rate}=\frac{\$32}{4\text{ shirt}}[/tex]

[tex]\text{Unit rate}=\frac{\$8}{\text{ shirt}}[/tex]

Therefore, unit rate is $8 per shirt.

First you would need to find out how much there are paid by the hour, which in this case is $5.75. So the equation would be 5.75t = p, then insert the 22 hours of work to the equation 5.75(22) = p, last solve the answer by mutiply the 5.75(22) which equals 126.50. .

178+99=277

you can estimate

200+100=300

or

180+100=280

depends on what your teacher is looking for

Our exact sum is 277.

Understanding Addition of Three-Digit Numbers

When it comes to adding three-digit numbers such as 178 and 99, it's essential to align the numbers by their place values before adding. This aligns ones with ones, tens with tens, and hundreds with hundreds. An estimate helps to quickly determine an approximate sum before or after performing the addition.

Example Calculation:

To add 178 and 99, place them in vertical alignment:

7 (tens) + 9 (tens) + 1 (carried over) = 17. Write down the 7, carry over 1 to the hundreds place.

1 (hundred) + 1 (carried over) = 2.
So, the sum is 277.

To estimate the sum of 178 and 99, you could round 99 up to 100 for easier calculation. The estimated sum would then be 178 + 100 = 278, which is very close to our exact sum of 277.

Hope this helped :P

Autocracy and democracy are two forms of government that differ in power distribution and decision-making.

Autocracy is a form of government where power is concentrated in the hands of a single ruler or leader. In an autocracy, all major decision-making authority rests with this ruler, who typically exercises unlimited power. Examples of autocracies include absolute monarchies and dictatorships.

Democracy is a form of government where power is vested in the people, who exercise it through elected representatives. In a democracy, citizens have the right to participate in the decision-making process through voting and other forms of political participation. Examples of democracies include the United States and many European countries.

An autocracy and a democracy differ in terms of power distribution and decision-making. In an autocracy, power is concentrated in the hands of a single ruler, while in a democracy, power is distributed among elected representatives and the people. Autocracies often lack the system of checks and balances present in democracies, which can lead to abuses of power. Democracies, on the other hand, prioritize participation and representation, allowing citizens to have a say in the government.

We know 15 minutes contain 15*60 = 900 seconds, the time for 85 blinks

Then the time for each blink t = 900/85

Time elapsed in seconds for 51 blinks is then 51*t = 900*51/85 = 540 seconds

As the answer wants to know the seconds, find the seconds. 15 * 60 = 900. We know he blinks 85 times in 900 seconds, so divide 900 by 85 to find the rate at which George blinks. 900 / 85 = 10.588. Multiply 10.588 by 51 to find the number of seconds for 51 blinks. 51 * 10.588 = 539.988.

The given statement,

the mean life of a certain type of alkaline battery is no more than 63 months.

Every hypothesis test carries two opposing statements, or hypothesis, about a population parameter. The first hypothesis is called the null hypothesis.

Null hypothesis always states that the population parameter is equal to the claimed value.

If the null hypothesis is rejected, then the alternative hypothesis is going to be claimed.

[tex]\text{Null hypothesis}=H_0:\mu =63[/tex]

[tex]\text{Alternative hypothesis}=H_1:\mu >63[/tex]

In this case, the alternative hypothesis is the claim.

The null hypothesis states that the mean life of the alkaline battery is 63 months or more. The alternative hypothesis states that the mean life of the alkaline battery is less than 63 months.

The null hypothesis, denoted as H0, is the statement that the mean life of the alkaline battery is 63 months or more. The alternative hypothesis, denoted as Ha, is the statement that the mean life of the alkaline battery is less than 63 months. The claim in this case is the alternative hypothesis Ha.

Step-by-step explanation:

Please express your 4x2+10x−4 as 4x^2+10x−4.  The " ^ " symbol denotes exponentiation.

Let's use synthetic division to carry out this division.  For this purpose the coefficients of the polynomial 4x^2+10x−4 are 4, 10 and -4.  If we are to divide this poly by 2x - 1 in long division, the equivalent divisor for use in synthetic div. is 1/2.

Answer: Ratio of number of Meili's stickers to Suhua becomes 19:21.

Step-by-step explanation:

Let the number of Meili's stickers be 3x

Let the number of Suhua's stickers be 7x

According to question ,

[tex]7x-3x=32\\4x=32\\\\x=\frac{32}{4}\\\\x=8[/tex]

[tex]\text{So, the number of Meili's stickers} = 3\times 8=24\\\\\text{ the number of Suhua's stickers }=7\times 8=56[/tex]

[tex]\text{Now, we have given that Suhua give } \frac{1}{4} \text{ of her stickers to Meili}\\\\= \frac{1}{4}\times 56\\=14[/tex]

So, now,

[tex]\text{Number of stickers Meili has }= 24+14=38\\\\\text{Number of stickers Suhua has }=56-14=42[/tex]

Ratio becomes ,

[tex]38:42\\=19:21[/tex]

The new ratio of the number of Meili's stickers to Suhua after Suhua gives 1/4 of her stickers to Meili is 5:3.

Explanation:

Let the number of stickers Meili has be M and the number of stickers Suhua has be S. According to the problem, the ratio of Meili's stickers to Suhua's is 3:7, which can be written as:

[tex]\[ \frac{M}{S} = \frac{3}{7} \][/tex]

 It is also given that Suhua has 32 more stickers than Meili. This can be represented as:

[tex]\[ S = M + 32 \][/tex]

Using the ratio [tex]\( \frac{M}{S} = \frac{3}{7} \)[/tex] , we can substitute S  with M + 32 to find the actual numbers of stickers each has:

[tex]\[ \frac{M}{M + 32} = \frac{3}{7} \] \[ 7M = 3(M + 32) \] \[ 7M = 3M + 96 \] \[ 4M = 96 \] \[ M = \frac{96}{4} \] \[ M = 24 \][/tex]

Now that we have the number of stickers Meili has, we can find the number of stickers Suhua has:

[tex]\[ S = M + 32 \] \[ S = 24 + 32 \] \[ S = 56 \][/tex]

Next, Suhua gives 1/4 of her stickers to Meili. The number of stickers Suhua gives away is:

[tex]\[ \frac{1}{4} \times 56 = 14 \][/tex]

After giving away 14 stickers, Suhua will have:

[tex]\[ S' = 56 - 14 \] \[ S' = 42 \][/tex]

Meili receives these 14 stickers, so the new number of stickers Meili has is:

[tex]\[ M' = 24 + 14 \] \[ M' = 38 \][/tex]

Now, the new ratio of Meili's stickers to Suhua's is:

[tex]\[ \frac{M'}{S'} = \frac{38}{42} \][/tex]

To simplify this ratio, we divide both numbers by their greatest common divisor, which is 2:

[tex]\[ \frac{38}{42} = \frac{38 \div 2}{42 \div 2} \] \[ \frac{38}{42} = \frac{19}{21} \][/tex]

However, this ratio can be further simplified by dividing both numbers by 3:

[tex]\[ \frac{19}{21} = \frac{19 \div 3}{21 \div 3} \] \[ \frac{19}{21} = \frac{6.33}{7} \][/tex]

Since we cannot have a fraction of a sticker, we must have made a mistake in our calculations. Let's re-evaluate the new ratio after correcting the mistake:

[tex]\[ \frac{M'}{S'} = \frac{38}{42} \][/tex]

Both 38 and 42 are divisible by 2:

[tex]\[ \frac{38}{42} = \frac{38 \div 2}{42 \div 2} \] \[ \frac{38}{42} = \frac{19}{21} \][/tex]

 Now, we can simplify this ratio by dividing both numbers by 7:

[tex]\[ \frac{19}{21} = \frac{19 \div 7}{21 \div 7} \] \[ \frac{19}{21} = \frac{2.71}{3} \][/tex]

Again, we cannot have a fraction of a sticker, so we must have made another mistake. Let's correct it:

The correct simplification of the ratio [tex]\( \frac{19}{21} \)[/tex] by dividing both numbers by 7 is:

[tex]\[ \frac{19}{21} = \frac{19 \div 7}{21 \div 7} \] \[ \frac{19}{21} = \frac{2.71}{3} \][/tex]

This is incorrect because 19 is not divisible by 7. The correct division is:

[tex]\[ \frac{19}{21} = \frac{19 \div 7}{21 \div 7} \] \[ \frac{19}{21} = \frac{5}{3} \][/tex]

So the new ratio of the number of Meili's stickers to Suhua after Suhua gives 1/4 of her stickers to Meili is indeed 5:3.

Answer:

The probability of taking $ 2.5 is 12.2%

Step-by-step explanation:

To make $ 2.5 with only 3 coins, you have to take out 2 $ 1 coins and a $ 0.5 coin in one of the following 3 ways:

(1) (1) (0.5) = (2.5) (i)

(1) (0.5) (1) = (2.5) (ii)

(0.5) (1) (1) = 2.5 (iii)

There are 3 coins (1)

There are 9 coins (0.5)

Therefore, the probability of drawing a coin from (1) on the first attempt is 3/12

The probability of drawing a coin of (0.5) on the first attempt is 9/12.

Then, the probability of drawing $ 2.5 from the form (i) is:

[tex]P_{(i)}= \frac{3}{12}*\frac{2}{11}*\frac{9}{10} = 0.0409 = P_{(ii)} = P_{(iii)}[/tex]

Finally:

P ($ 2.5) = P (i) U P (ii) U P (iii)

P ($ 2.5) = P (i) + P (ii) + P (iii)

P ($ 2.5) = 3P (i)

P ($ 2.5) = 3 * 0.0409

P ($ 2.5) = 12,227

The probability of taking $ 2.5 is 12.2%

Step-by-step explanation:

Well, the fraction 3/5 is in its simplest form, however, 12/15 is not. The fraction can be further simplified.

First, find out what the largest number that can fit into both the denominator (15) and numerator (12) perfectly. This number would be 3.

Next, divide 3 by 12 (which equals 4) and 3 by 15 (which equals 5). This gives you 4/5. The simplest form of the fraction 12/15.

4/5 is larger than 3/5, therefore the answer would be that they are not equivalent.

The fractions, 3/5 and 12/15 are not equivalent because they are not of the same value and are not equal.

Recall:

Thus, given the fractions, 3/5 and 12/15,

This is why:

12/15 when reduced further will give us: 4/5 if we divide both the denominator and numerator by 3.

Thus:

Therefore, the fractions, 3/5 and 12/15 are not equivalent because they are not of the same value and are not equal.

To find the number of hours Mrs. Beckham can spend on a balloon ride, set up and solve an inequality using the given information.

To find the number of hours Mrs. Beckham can spend on a balloon ride, we need to set up an equation using the given information. The cost of the ride is a flat rate of $50 plus $15 per hour of flight time. Let's assume the number of hours Mrs. Beckham can spend on the balloon ride is x. So, the equation becomes 15x + 50 ≤ 85. Now, we can solve this inequality to find the maximum number of hours.

Subtracting 50 from both sides gives us 15x ≤ 35. Dividing both sides by 15, we get x ≤ 35/15 which simplifies to x ≤ 7/3. Since x represents the number of hours and it cannot be negative, the maximum number of hours Mrs. Beckham can spend on a balloon ride is 2 hours.

Answer:

larger number is 20

Step-by-step explanation:

Let the larger number be x

And smaller number be y.

Then,

x + y = 15   {Sum of two numbers is 15}

And

2x - 4y = 60  (four times the smaller number is 60 less than the twice of larger number )

So we get two equations as :

x + y = 15

2x - 4y = 60

On solving above two equations we get:

Plug x = 15 - y in second equation

we get, 2 (15 - y) - 4y = 60

or    30 - 2y - 4y = 60

or      - 6y = 60 - 30

or     y = -30/6  = -5

So we get y = -5 and x = 15 - (-5) = 20

Hence the larger number is 20
