1 quart = 4 cups
1 cup = 8 ounces
Solution: ____ glasses
Answer: 32 glasses
Step-by-step explanation: If 1 quart is 4 cups and 8 ounces are in 1 cup, 8x4=32 so there are 32 ounces in a quart. If he has 6 quarts 32x6+192 ounces. if each glass is 6 ounces 192/6=32.

Answer:
45.4
Step-by-step explanation:
A=πr2=π·3.82≈45.3646
The numerator of a fraction is 19 less than the denominator of the fraction. GIve that the fraction 2/9 is obtained when 1 is subtracted from the numerator and 1 is added to the denominator, fing the original fraction.
Answer:
[tex]\frac{7}{26}[/tex]
Step-by-step explanation:
let x be the denominator of the fraction then x - 19 is the numerator , so
[tex]\frac{x-19}{x}[/tex] ← is the original fraction
subtrating 1 from the numerator and adding 1 to the denominator , then
[tex]\frac{x-20}{x+1}[/tex] = [tex]\frac{2}{9}[/tex] ( cross- multiply )
9(x - 20) = 2(x + 1) ← distribute parenthesis on both sides
9x - 180 = 2x + 2 (subtract 2x from both sides )
7x - 180 = 2 ( add 180 to both sides )
7x = 182 ( divide both sides by 7 )
x = 26
Then the original fraction is
[tex]\frac{26-19}{26}[/tex] = [tex]\frac{7}{26}[/tex]

Find the equation of a straight line which is perpendicular to the line
which
passes through the point (3, -2).
Answer:
I don't see the equation for the line, but I describe the process.
Step-by-step explanation:
Let's look for a line that has the form y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).
The slope of a perpendicular line is the negative inverse of the slope of the reference line. In this case the equation for the reference line is missing. If it is in the form y=mx+b, take the m value, invert it, and then give it a "-" sign. For example, if the line is y = 2x +1, the negative inverse of the slope of 2 would be -(1/2).
The new line will have this new slope [-(1/m)] to make it y = -(1/m)x + b.
To find b, use the given point of (3,-2) in the equation and solve for b:
y = -(1/m)x + b
-2 = -(1/m)*(3) + b
Then solve for b and you'll have the equation for the solution to the problem.

OC is the radius of the circle (O is the center of the circle).
AD is the tangent to the circle at point C
When a radius of a circle meets with a tangent of the same circle, the angle between them is 90°
<ACB = <ACO = 90°
<ABC = 180 - (<ACB + <BAC)
= 180-(90+40)

Solve for t.
–17 = –9 + 4t
Answer:
[tex]\boxed{\sf{t=-2}}[/tex]Step-by-step explanation:
To solve for t, you have to isolate it on one side of the equation.
-17=-9+4tFirst, you have to switch sides.
→ -9+4t=-17
Add by 9 from both sides.
[tex]\Longrightarrow: \sf{-9+4t+9=-17+9}[/tex]
Then, you solve it.
-17+9=-8
4t=-8
Divide by 4 from both sides.
[tex]\sf{\dfrac{4t}{4}=\dfrac{-8}{4}}[/tex]
Solve.
Divide the numbers from left to right.
-8/4=-2
[tex]\Longrightarrow: \boxed{\sf{t=-2}}[/tex]
Therefore, the correct answer is t=-2.I hope this helps. Let me know if you have any questions.
Answer:
[tex]t = -2[/tex]
Step-by-step explanation:
Step 1: Add 9 to both sides
[tex]-17 = -9 + 4t[/tex]
[tex]-17 + 9 = 4t - 9 + 9[/tex]
[tex]-8 = 4t[/tex]
Step 2: Divide both sides by 4
[tex]\frac{-8}{4} = \frac{4t}{4}[/tex]
[tex]-2 = t[/tex]
Answer: [tex]t = -2[/tex]

A penquin dives at 18 feet per minute how many minutes does it take to
dive to -54 feet?
3 Minutes
30 Seconds
5 Minutes
4 Minutes
Answer:
5 minutes
Step-by-step explanation:
it dives at positive 18 feet in a minute
however in order to dive at -54 feet, it must dive -5 times
18-18-18-18-18= -54
and 1min =18feet
so it needs 5minutes for the 5times
OR
Let x=the time needed to dive at -54 feet's
so 1min=18
x= -54
-54=18x
dividing both sides by 18
-54/18=18x/18
x=-54/18
x=-5
however time cannot be negative
therefore x =5
this implies that the penguin dives at -54 feet in 5 minutes.

The area of a sector of a circle with a radius measuring 15 cm is 75(pi) cm2. What is the measure of the central angle that forms the
sector?
The sector of the circle is bounded by 2 radii, and the measure of the central angle that forms the sector is 120 degrees
How to determine the central angle?The given parameters are:
Area = 75π cm^2Radius, r = 15 cmThe area is calculated using
Area = α/360 * πr^2
So, we have:
α/360 * π * 15^2 = 75π
Evaluate the exponent
α/360 * π * 225 = 75π
Divide both sides by 75π
α/360 * 3 = 1
Multiply
α/120 = 1
Multiply both sides by 120
α = 120
Hence, the measure of the central angle that forms the sector is 120 degrees

4. The length of a rectangle is 18 centimeters and the width is 6 centimeters. A similar
rectangle has a width of 10 centimeters. What is the length of the missing side?
Answer:
30 cm
Step-by-step explanation:
So what we are given here is a case of similar figures.
When we are given similar figures, the ratio of the width of both figures should be similar to the ratio of the length of both figures.
I'll demonstrate it in the following problem.
We know one rectangle has a length of 18 cm and a width of 6cm.
The other rectangle has a width of 10 cm.
Let's take a ratio of the width of both rectangles.
We take the width of 6 cm for the first rectangle to the width of 10 cm for the second rectangle.
w1 = 6 cm
w2 = 10 cm
6 cm : 10 cm = 3 : 5
The ratio given is 3 : 5. Let's use these ratios to find lengths.
l1 = 18 cm
l2 = x cm
3 : 5 = 18 : x
To find x, we just solve this like an equation, where we let ratios be division signs.
3/5 = 18/x
Multiply both sides by 5x
3x = 90
Divide both sides by 3
x = 30 cm
The length of the missing side is 30 cm. We found the answer to the length by using the ratios obtained from the widths.
