Answer:

$7.28

Step-by-step explanation:

We have been given that Brandon buys a basket of flowers for $7 before tax. The sales tax is 4%.

The total price that Brandon paid for the basket of flowers will be equal to 7 plus 4% of 7.

We can represent this information in an equation as:

[tex]\text{The total price that Brandon paid for the basket of flowers}=7+(\frac{4}{100}\times 7)[/tex]

[tex]\text{The total price that Brandon paid for the basket of flowers}=7+(0.04\times 7)[/tex]

[tex]\text{The total price that Brandon paid for the basket of flowers}=7+0.28[/tex]

[tex]\text{The total price that Brandon paid for the basket of flowers}=7.28[/tex]

Therefore, the total price paid by Brandon for the basket of flowers was $7.28.

Answer:

Total price Brandon pays for the basket of flowers is, $7.28

Step-by-step explanation:

As per the given statement: Brandon buys a basket of flowers for $7 before tax.

Convert this $7 into cents.

1 dollars = 100 cents.

$7 = 700 cents.

It is also given that the sales tax is 4%.

then;

Sales tax = [tex]4\% \times 700 = \frac{4}{100} \times 700 = 4 \times 7 =28 cents[/tex]

Total price Brandon pays = Price of Brandon buys a flower before tax + sales tax price

=  700 + 28 = 728 cents = $7.28

Therefore, the total price Brandon pays for the basket of flowers is, $7.28

Answer:

106.63%.

Step-by-step explanation:  

We have been given that at the end of 2005, this price was $513. At the end of 2015, it was $1060.

To find the percentage of the price per ounce of gold increase we will use % increase formula.

[tex]\text{Percent Increase}=\frac{\text{Final value-Initial value}}{\text{Initial value}}\times 100[/tex]

Let us substitute our given values in above formula.

[tex]\text{Percent Increase}=\frac{1060-513}{513}\times 100[/tex]

[tex]\text{Percent Increase}=\frac{547}{513}\times 100[/tex]

[tex]\text{Percent Increase}=1.0662768031189084\times 100[/tex]

[tex]\text{Percent Increase}=106.62768031189084\approx 106.63[/tex]

Therefore, the price of per ounce of gold increased by 106.63%.

Answer:107

Step-by-step explanation:

So if it is incorrect for the other answer this is the answer, so do 1060-513=547, so it increased by that much, then divided 547/513= 1.06627680312 But that rounds up to 7 and since we know that the original was 100% of its amount we would add 100+7 which would be 107%

Step-by-step explanation:

Let s be charges for a single room and d be charges for a double room per night.

We are told that a hotel has 150 rooms. We can represent this information as:

[tex]s+d=150...(1)[/tex]

The charges for a double room are $270 per night and $150 per night for a single room. So the charges for s single rooms will be 150s and charges for d double rooms will be 270d.

On a night when the hotel was completely occupied. Revenues were $33,300.

We can represent this information as:  

[tex]150s+270d=33,300...(2)[/tex]

Therefore, our desired pair of equations will be:

[tex]s+d=150...(1)[/tex]

[tex]150s+270d=33,300...(2)[/tex]

Answer: First equation: s+d=150; second equation: 150s+270d=33300

Step-by-step explanation: To solve the given problem we need to write two equations, the first one will express that the total number of rooms is the sum of the single rooms an the double rooms. The second equation will include the sum of the total earnings for the single and double rooms:

First equation:

s+d=150 (the single rooms and the double rooms equal 150 rooms)

second equation:

150s+270d=33300  (the sum of the single and double rooms each one of them multiplied by their prices, equals the total revenue)

To solve the equation we isolate s from the first equation:

s=150-d

and we replace it in the second one:

150(150-d)+270d=33300

solving for d:

22500-150d+270d=33300

120d=33300-22500

120d=10800

d=10800/120

d=90.

now we calculate s from the first equation:

s=150-d

s=150-90

s=60.

There are 60 single rooms and 90 double rooms.

Answer:

B

Step-by-step explanation:

We have dollars and dollars per pack, so we divide to get how many packs.

[tex] \dfrac{21.75}{1.75} = \dfrac{2175}{175} = \dfrac{87(25)}{7(25)} = \dfrac{87}{7} \approx 12.4[/tex]

Odd that it's not a whole number of packs; please check the question carefully.  Let's say she bought 12 and got some change.

My guess is the question really says Alice spent $22.75, so she bought 13 packs.  Again check the question carefully.  You don't need us to divide two numbers.

Final answer:

Luke can make 20 servings with 5 pounds of ground turkey.

Explanation:

To determine the number of servings Luke can make with 5 pounds of ground turkey, we need to set up a proportion. The recipe calls for 1.5 pounds of ground turkey for every 6 servings. So, we can set up the proportion: 1.5 pounds / 6 servings = 5 pounds / x servings, where x represents the unknown number of servings. To solve for x, we cross multiply: 1.5 pounds * x servings = 5 pounds * 6 servings. Simplifying the equation, we get: 1.5x = 30. Dividing both sides by 1.5, we find that x = 20. Therefore, Luke can make 20 servings with 5 pounds of ground turkey.

Answer: Choice B

We start with SU = UT being given, and so is SV > VT.

The second line is UV = UV by the reflexive property to help us use the converse of the hinge theorem next.

The hinge theorem basically says that the more open an angle is, the larger the opposite side will be (the side opposite from the angle that varies). Imagine a door opening and closing. The further open it gets, the longer the rope will be that connects the door handle to the frame. Going in reverse, the converse says that if the opposite side of the angle gets bigger, then the angle itself gets bigger as well. The hinge theorem is handy to help compare two sides even if we don't know their exact lengths (we can figure out which side is larger than the other)

The conditions given that SU is congruent to UT and SV is greater than VT create a scenario where we can prove that the measure of angle SUV is greater than the measure of angle TUV.

Given that SU≅UT means that segment SU is congruent to segment UT, and SV>VT meaning that segment SV is greater than segment VT, this sets up two important conditions for the triangle SUV. First, as SU is congruent to UT, this implies that ∠SUV is congruent to ∠TUV due to the Base Angles Theorem (If two sides of a triangle are congruent (equal), then angles opposite these sides are congruent). However, SV>VT creates an inequality which contradicts this, pointing towards the fact that ∠SUV is greater than ∠TUV.

Answer:

Hello.

The answer is $6 each item.

Step-by-step explanation:

If all of the items are the same price, then we have a total of 7 items ( 3 keyboards + 4 mic = 7 items).

So at the end is: 7 items ÷ $42 = $6.

The cost of each item is $6.

A division is a process of splitting a specific amount into equal parts.

Given that Mr. Vargas is buying used computer equipment. He buys 3 keyboards and 4 mice. He spends $42.

Since, cost of each item is same, therefore total item = (3 + 4) = 7

Let the cost of each item be c,

7c = 42

c = 6

Hence, The cost of each item is $6.

Answer:

2.54 cm/1 inch

Step-by-step explanation:

We have inches.  That is in the numerator.  We need to convert to cm.  So our conversion factor should have cm in the numerator and inches in the denominator.

1 in = 2.54 cm

Divide both sides by 1 inc

A conversion factor is equal to 1

1 = 2.54 cm/1 inch

The correct unit conversion fraction to convert inches to centimeters is 2.54 cm/1 in. Apply this factor to the length in inches (11 inches) to obtain the length in centimeters (27.94 cm).

To convert a length in inches to centimeters, we can use a unit conversion fraction. In this case, because there are 2.54 centimeters in one inch, the correct unit conversion fraction to use is A. 2.54 cm/1 in. This means that we multiply the length in inches by the conversion factor to get the length in centimeters. Here is the step-by-step process for your problem:

In a dilation, size is not preserved. Triangles must have the same shape and size in order to be congruent. If it is dilated by 2/3, then it gets smaller, and is therefore not the same size.

Final answer:

Triangle QRS is not congruent to triangle ABC after a dilation of  [tex]\frac{2}{3}[/tex], but the two triangles are similar because their corresponding angles are equal and sides are proportional.

Explanation:

The question concerns the concept of congruent and similar triangles in geometry. When triangle QRS is dilated about the origin by a scale factor of [tex]\frac{2}{3}[/tex] to create triangle ABC, the two resulting triangles are not congruent because their corresponding sides are not equal in length. However, they are similar since the angles remain the same and the sides are proportional. Congruent triangles are identical in both shape and size, but similar triangles maintain the same shape while the size can vary in proportion.
