Answer:
The value of x is 2.7320
Step-by-step explanation:
.
Answer:
5x = 81.2, in order to find out the value of x, we need to isolate the variable by performing inverse operations on both sides of the equation.
5x = 81.2, when we look at 5x we can see that x and 5 are being multiplied.
The inverse operation of multiplication is division so we divide by 5 from both sides:
5x = 81.2.
÷5 ÷5
x = 16.24, and now since they want us to round to the nearest ten-thousandths, it is not needed because it does not reach the thousandths place so your answer is 16.24.
We can also double check this by replacing x with the value we found:
5x = 81.2
5(16.24) = 81.2
81.2 = 81.2, so it is correct because both match.

What is the vertical distance from the orgin to the point (6,3)
Answer:
3.
Step-by-step explanation:
The y axis is vertical, and the origin is (0, 0). Therefore, since 3 is the y, the vertical distance is 3 and the horizontal, if you need it, is 6.
The cheerleaders from Newberg High School are doing a giftwrapping fundraiser at a clothing
store. Yesterday, they wrapped 26 small clothing boxes and 39 large clothing boxes, using a
total of 468 feet of wrapping paper. The day before, they wrapped 28 small clothing boxes
and 39 large clothing boxes, using a total of 480 feet of gift wrap. How much paper does it
take to wrap each size of box?
Each small box uses
feet of paper and each large one uses
feet.
Answer:
Step-by-step explanation:
It takes 8 feet to wrap the small box and 12 feet to wrap the large box
Step-by-step explanation:
The cheerleaders from Campo high school are doing a gift wrapping fundraiser at a clothing store
Yesterday, they wrapped 36 small clothing boxes and 25 large clothing boxes, using a total of 588 feet of wrapping paper
The day before, they wrap 27 small clothing boxes and 29 large clothing boxes, using a total of 564 feet of gift wrap
We need to find how much paper it takes to wrap each size of box
Assume that they need x feet to wrap a small box and y feet to wrap a large box
∵ The small box is wrapped by x feet
∵ The large box is wrapped by y feet
∵ They wrapped 36 small clothing boxes and 25 large clothing
boxes, using a total of 588 feet
∴ 36x + 25y = 588 ⇒ (1)
∵ They wrapped 27 small clothing boxes and 29 large clothing
boxes, using a total of 564 feet
∴ 27x + 29y = 564 ⇒(2)
Now we have a system of equation to solve it
Multiply equation (1) by -3 and equation (2) by 4 to eliminate x
∵ -108x - 75y = -1764 ⇒ (3)
∵ 108x + 116y = 2256 ⇒ (4)
- Add equations (3) and (4)
∴ 41y = 492
- Divide both sides by 41
∴ y = 12
- Substitute the value of y in equation (1) or (2)
∵ 27x + 29(12) = 564
∴ 27x + 348 = 564
- Subtract 348 from both sides
∴ 27x = 216
- Divide both sides by 27
∴ x = 8
It takes 8 feet to wrap the small box and 12 feet to wrap the large box

A restaurant has a policy in which an automatic gratuity of 18% is added to a table's bill when the table has 8 or more people. A bill for a large table comes to $510 before the gratuity is added. The total cost of the meal is divided evenly among 15 people at the table. How much does each person pay?
please help.
Answer:
40 dollars and 12 cents
Step-by-step explanation:
So since there are more than 8 people on the table, we can say that there will be an 18% gratuity that will be added to the final bill.
510+18%(510)
510+0.18×510
510+91.8
601.8$ is the total bill
since there are 15 people
601.8/15=40.12

for $263.89. How much is in Kim's checking
account now?
Answer:
Kim's checking account has $396.76 left.
Step-by-step explanation:
Kim had $472.15 in her checking account. She deposited $188.50 and wrote a check for $263.89. How much is in Kim's checking account now?
The equation tells us that Kim added 188.5 to the original 472.15 in her checking account. 472.15 + 188.5 = 660.65But then the equation also says she took out, or wrote a check, for 263.89. 660.65 - 263.89 = 396. 76 This means that kim's checking account has $396.76 left.I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS

15x+10y=8xy+28x find an expression for y in terms of x
Answer:
y = [tex]\frac{13x}{10-8x}[/tex]
Step-by-step explanation:
15x + 10y = 8xy + 28x ( subtract 15x from both sides )
10y = 8xy + 13x ( subtract 8xy from both sides )
10y - 8xy = 13x ← factor out y from each term on the left side
y(10 - 8x) = 13x ← divide both sides by (10 - 8x)
y = [tex]\frac{13x}{10-8x}[/tex]
Answer:
y = 13x/10-8x
Step-by-step explanation:
15x + 10y = 8xy + 28x
10y = 8xy + 13x
10y - 8xy = 13x
y(10 - 8x) = 13x
y = 13x/10-8x

Line m is tangent to the circle. Find the indicated measure
Answer:
105°
Step-by-step explanation:
The measure of an inscribed angle is half the measure of the arc it subtends. For an arc of 210°, an inscribed angle that subtends it will have a measure of 105°.
We normally think of the sides of an inscribed angle as being a chord. However, that chord can be considered part of a secant. When the two points of intersection with the circle get arbitrarily close together, the chord becomes a point, and the secant becomes a tangent.
That is, the angle made by this geometry is simply a degenerate case of an inscribed angle. The relationship with the arc measure is unchanged.
m∠1 = 105°

Equation of circle: (x – h)² + (y – v)² = r²Let's plot the circles one by one.
Circle A:
Finding x and y:
(x,y) = (0,0) ⇒ x = 0, y = 0Substitute the radius and the coordinates in the equation:
(x – h)² + (y – v)² = r²(0 – h)² + (0 – v)² = 6²Plot the equation on the graph to obtain circle A.

Circle B:
Finding x and y:
(x,y) = (-4,-2) ⇒ x = -4, y = -2Substitute the radius and the coordinates in the equation:
(x – h)² + (y – v)² = r²(-4 – h)² + (-2 – v)² = 4²Plot the equation on the graph to obtain circle B.

The scale of a map is 1:3,000,000. What is the actual distance in km corresponding to 12 cm on the map?
3600 km
360 km
36 km
3.6 km
Answer:
Step-by-step explanation:
The scale number can be interpreted as (1cm/3,000,000 km), a conversion factor. Since it is a conversion factor, we can invert it to the form:
(3,000,000 km/1cm)
A measure of 12cm on the map would correspond to:
(12cm)*((3,000,000 km/1cm) = 42,000,000 km
Wow - a long trek, if you need water.
Note that inverting the conversion factor isn't totally necessary, since we could use the original form and divide:
12 cm/(1cm/(3,000,000km)) = 42,000,000 km
But I dislike division, so I always invert a conversion factor if it makes the calculation more convenient, for me.
