1/2 of what number is 7 times 3?
By setting up the question as an algebraic equation, 1/2 * x = 21, and solving for x, it's determined that half of 42 is equal to 21.
Explanation:The question we're looking to solve is: "1/2 of what number is 7 times 3?" First, let's understand that 7 times 3 equals 21. The question asks which number, when halved, gives us 21. This can easily be set up as an algebraic equation: 1/2 * x = 21, where x represents the number we're trying to find.
To solve for x, we first multiply both sides of the equation by 2 to get rid of the fraction (1/2). This leaves us with: x = 21 * 2. Therefore, x = 42. The number, when cut in half, that results in 21, is 42.

a cookie recipe calls for 1 2/3 of sugar if you plan on changing the recipe to make it 2 1/2 times as much how many cups of sugar will you need
Pls show work
Answer:
[tex]4\frac{1}{6}\ cups[/tex]
Step-by-step explanation:
we know that
The recipe calls for 1 2/3 of sugar
To make 2 1/2 times the recipe
Multiply 2 1/2 by 1 2/3
Convert mixed numbers to an improper fraction
[tex]1\frac{2}{3}=\frac{1*3+2}{3}=\frac{5}{3}\ cups[/tex]
[tex]2\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}[/tex]
so
[tex]\frac{5}{2}(\frac{5}{3})=\frac{25}{6}\ cups[/tex]
Convert to mixed number
[tex]\frac{25}{6}=\frac{24}{6}+\frac{1}{6}=4\frac{1}{6}\ cups[/tex]
Final answer:
To find out how much sugar is needed for the new recipe that is 2 1/2 times as much, follow the three-step process.
Explanation:
To find the amount of sugar needed:
Calculate 1 2/3 cups of sugar is equal to 5/3 cups of sugar.
Multiply 5/3 by 2 1/2, which equals 25/6.
Convert 25/6 to a mixed number, which is 4 1/6 cups of sugar needed for the new recipe.
Deborah spends 1/5 of her consulting time writing grant proposa
her consulting time writing grant proposals. If she spends 48 hours per month
writing grant proposals, how much time does she spend on consulting work?
Deborah spends 240 hours per month on consulting work. This was calculated by understanding 48 hours is 1/5 of her time, and multiplying it by 5 to find the total hours.
Explanation:The subject of this question is mathematics, and it involves the concept of fractions to solve a real-world problem. Deborah spends 1/5, or 20% of her time, writing grant proposals. If she spends 48 hours per month on this task, 48 hours represents 1/5 of her total consulting time.
To find the total consulting time, we need to do these steps: divide 48 by 1 to get 48 (since 48 hours is the 1/5), then multiply 48 by 5 (the denominator of the fraction, which represents the whole).
So, 48 (hours) divided by 1 equals 48, and 48 multiplied by 5 equals 240. Therefore, Deborah spends 240 hours per month on consulting work.

What is the minimum number of members of the Senate that must approve a treaty for it to go
into effect?
Answer:
Two thirds of the Senate must approve it
The minimum number of Senate members needed to approve a treaty is two-thirds of the Senate.
Explanation:The minimum number of members of the Senate that must approve a treaty for it to go into effect is two-thirds (⅔) of the Senate. The Constitution of the United States, Article II, Section 2, Clause 2 states that the President has the power to make treaties, but they require the advice and consent of the Senate.
For example, if the Senate has 100 members, then 67 votes would be needed to approve a treaty for it to go into effect. However, it is important to note that the Senate may require a supermajority vote, which would mean a higher percentage of approval than two-thirds, depending on their rules and procedures.

The original price was 142 dollar.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a' the percent that considered thing is of "a" is b%. Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts.
We are given that store is having a 20% off sale. If the reduced
price of an item is $126.40,
We need to find the original price.
Therefore, we can write as ;

To find the original price of the item that was reduced by 20% to $126.40, divide the sale price by 0.80, which yields an original price of $158.00.
To determine the original price of an item that has been marked 20% off, we need to work backward from the sale price. The sale price represents 80% of the original price because 100% - 20% = 80%.
The question is provided with the reduced price which is $126.40. To find the original price, we divide the reduced price by 0.80.
Express 20% as a decimal: 0.20.Subtract this from 1 to find the percentage of the original price represented by the sale price: 1 - 0.20 = 0.80.Divide the sale price by this decimal: $126.40 / 0.80 = $158.00.Therefore, the original price of the item was $158.00.

Answer:
Rafael gets $4,32 In tips. The old lady gets $41.68 in change.
Step-by-step explanation:

$54 * 8%/100% = $4,32
Rafael gets $4,32 In tips.
Step 2: Now we must calculate the change the old lady receives. For this, we must subtract from the $100 that she gives the part corresponding to the payment for food and the part corresponding to the tip.
$100 - $54 - $4,32 = $41,68
The old lady gets $41.68 in change.

5,500,000 in expanded form
Answer:
5,500,000 = (5 x 100000000) + (0 x 10000000) + (5 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)
Step-by-step explanation:
The expanded form of 5,500,000 is (5 x 1000000) + (5 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1).
What is an expanded form?
The expanded form of the number is the splitting of numbers based on the place value, such as ones, tens, hundreds, thousands, ten thousands,and so on. The number that is represented by the sum of each digit multiplied by its place value is called the expanded form of the number.
Now the given number is,
5,500,000
Now each digit place value is given as,
5 = (5 x 1000000)
5 = (5 x 100000)
0 = (0 x 10000)
0 = (0 x 1000)
0 = (0 x 100)
0 = (0 x 10)
0 = (0 x 1)
Adding this together, we get
5,500,000 = (5 x 1000000) + (5 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1).
Hence, The expanded form of 5,500,000 is (5 x 1000000) + (5 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1).

A law states that a freight truck cannot travel under a low overpass. There must be at least 3 feet of clearance. The sign on an overpass states that the overpass is 18 feet above the road's surface. Suppose the height of a truck is 13.6 feet. In inches, what is the ADDITIONAL amount of clearance between the truck and the overpass after the state law has been followed?
Answer:
D. 16.8
Step-by-step explanation:
It is right trust me!!!
Answer:
Additional amount of clearance between the truck and overpass is 16.8 inches.
Step-by-step explanation:
A law states that a a freight truck must have the clearance of at least 3 feet to travel under the a overpass.
Sign on an overpass states that the overpass is 18 feet above the road's surface.
Height of the truck is 13.6 feet.
As per rule height of overpass from the road must be height of the truck + clearance.
Additional amount of clearance between the truck and the overpass
= Distance between the road and the overpass - (height of the truck + clearance)
= 18 - (13.6 + 3)
= 18 - 16.6
= 1.4 feet
Since 1.4 feet = 12 inches
1.4 feet = 12×1.4 = 16.8 inches
Therefore, additional amount of clearance between the truck and overpass is 16.8 inches.

how deep is the hole?
2ft
4ft
8ft
16ft
Answer:
Step-by-step explanation:
16 feet
Answer:
Option C.
Step-by-step explanation:
Let x be the distance from holes center in feet and y be the depth from level ground in feet.
The given table represents a quadratic functions.
x : -2 0 2
y : -6 -8 -6
The depth from level ground in feet is same at x=-2 and x=2 it means the hole is symmetric about the line x=0.
The value of a quadratic function is on its extreme at line of symmetry.
In the given function the line of symmetry is x=0. So, the depth of the hole is defined on x=0.
From the table it is clear that at x=0 the depth from level ground is 8 feet.
Therefore, the correct option is C.
For her birthday, Kendra received a gift card in the mail from her grandparents. The gift card was worth $50. Kendra thought, since she had just received other gifts for her birthday, she would wait a while to spend the gift card. Unfortunately, Kendra forgot all about the gift card, and the card loses $5 every month after its date of purchase if it has not been used.
If Kendra forgot the card for three months, she lost $______.
Answer:
She lost $15 on her 50 dollar credit card.
Explanation:
Since Kendra looses 5$ each month, we have to look at how many months the card was left unused. The card was left unused for 3 months. Multiply the $5 by 3 months to get $15. Her card is now at $35
The amount of money Kendra lost in her gift card is required.
Kendra lost $15.
Initial value of the gift card = $50
Money lost per month = $5
Let M be the number of months after the gift card was bought.
The money lost after M months passed would be
[tex]5M[/tex]
Kendra forgot about the gift card for 3 months
So, [tex]M=3[/tex]

If |z - 7| - 2 = 2, then z = -3 /amp; z = -11 true or false
Answer:
False
Step-by-step explanation:
The absolute value always returns a positive value, however the expression inside can be positive or negative, that is
Given
| z - 7 | - 2 = 2 ( add 2 to both sides )
| z - 7 | = 4, then
z - 7 = 4 OR - (z - 7) = 4
z = 4 + 7 = 11 OR
- z + 7 = 4
- z = 4 - 7 = - 3 ( multiply both sides by - 1 )
z = 3
As a check
z = 11
| 11 - 7 | - 2 = | 4 | - 2 = 4 - 2 = 2 ← True
z = 3
| 3 - 7 | - 2 = | - 4 | - 2 = 4 - 2 = 2 ← True
Hence z = 11 or z = 3 are the solutions
−2 1/4=r−4/5
What is r?
Answer:
r = -29/20 or r = -1.45
Step-by-step explanation:
I believe you are saying that the equation is -2 1/4 = r - 4/5. If so, then I would solve it in this way:
-2 1/4 = r - 4/5
-9/4 = r - 4/5
-9/4 (20) = r (20) - 4/5 (20)
-45 = 20r - 16
20r = -29
r = -29/20
r = -1.45
Check:
-2 1/4 = r - 4/5
-9/4 = r - 4/5
-2.25 = r - 0.8
-2.25 = -1.45 - 0.8
-2.25 = -2.25
-9/4 = -9/4
The calculated value of variable r is r = -1.45.
What is equation?An equation is a mathematical statement that shows the equality between two expressions. It typically consists of variables, constants, and mathematical operations (e.g., addition, subtraction, multiplication, division) with an equal sign (=) in between.
To solve for r in the equation -21/4 = r - 4/5
Step 1: Add 4/5 to both sides of the equation to isolate r:
r = -2.25 + 4/5
Convert -2.25 to a fraction with a common denominator of 5:
r = (-11.25/5) + (4/5)
Add the fractions:
r = (-11.25 + 4)/5
Simplify:
r = -7.25/5
r = -1.45
So, r = -1.45.
