Answer:

It is just right

Step-by-step explanation:

Kermit's fav = 15 tea bags every 2 liters = 15/2 = 7.5 teabags per liter

Peggy made 90 teabags in 12 liters = 90/12 = 7.5 teabags per leter

Hence peggy used the same teabags per liter than kermit's favorite. It is just right.

edit: calculation error. corrected.

Your answer would be C:Just right.

Because:

2 liters of water = 15 tea bags

15/2 = 7.5 tea bags

Peggy needs to make 12 liters

12 x 7.5 = 90 tea bags

Conclusion:

Peggy's 12-liter batch of iced tea with 90 tea bags is JUST RIGHT.

Answer:

Part 1) The amount invested in the first account at 7% was $4,400

Part 2) The amount invested in the second account at 12% was $4,200

Step-by-step explanation:

we know that

The simple interest formula is equal to

[tex]I=P(rt)[/tex]

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

Let

x------> the amount invested in the first account at 7%

(8,600-x) -----> the amount invested in the second account at 12%

in this problem we have

[tex]t=1\ year\\ P1=\$x\\ P2=\$8,600-x\\ I=\$812\\r1=0.07\\r2=0.12[/tex]

substitute in the formula above

[tex]812=x(0.07*1)+(8,600-x)(0.12*1)[/tex]

[tex]812=0.07x+1,032-0.12x[/tex]

[tex]0.12x-0.07x=1,032-812[/tex]

[tex]0.05x=220[/tex]

[tex]x=\$4,400[/tex]

so

[tex]8,600-x=\$8,600-\$4,400=\$4,200[/tex]

therefore

The amount invested in the first account at 7% was $4,400

The amount invested in the second account at 12% was $4,200

Answer:

$4,400 at 7%

$4,200 at 12%

Step-by-step explanation:

Let the amount invested in 7% be x, so,

amount invested in 12% would be "8600 - x"

We can now write an equation and solve for x:

[tex]0.07(x)+0.12(8600-x)=812\\0.07x+1032-0.12x=812\\-0.05x=-220\\x=\frac{-220}{-0.05}=4400[/tex]

Thus, the amount invested in 12% is  8600 - 4400 = 4200

So,

$4,400 at 7%

$4,200 at 12%

Answer:

Step-by-step explanation:

f(x) = 18x + 3x^2

f(x) =  3x^2+18x

Factor out a 3

     = 3(x^2 +6x)

Take the coefficient of x, divide by 2 and then square

6/2 = 3 3^2 =9

Remember the 3 out side 3*9 =27 so we are really adding 27

3(x^2+6x+9) -3*9

The number inside the parentheses added to x is b/2  or 6/2

3(x+3)^2 -27

Answer:

[tex]f(x)=3(x+3)^{2}-27[/tex]

Step-by-step explanation:

In the last step is missing the number 3 which is the second term of the binomial squared expression.

Basically, the complete step is

[tex]f(x)=3(x+3)^{2}-27[/tex]

As you can see, the three inside the parenthesis is the missing part in the last step.

Answer:

The answer is 142°

Step-by-step explanation:

Because 38° and m∠2 are corresponding angles, m∠2 = 38°. Also, m∠2 and m∠5 are supplementary angles, which means the sum of their angles adds up to 180°. We can create the equation 38° + m∠5 = 180°. By subtracting 38° on both sides, we get m∠5 = 142°.

Answer:

∠1

Step-by-step explanation:

we know that

An inscribed angle in a circle is formed by two chords that have a common end point on the circle

The measure of the inscribed angle is half of measure of the intercepted arc

In this problem

∠1 is an inscribed angle

∠2 is an outer angle

∠3 is an interior angle

∠4 is an semi-inscribed angle ( angle formed by a chord and a tangent)

Answer:

1. Tangent ray: a ray that lies on a tangent line and contains the point of tangency;

2. Intercepted arc: an angle intercepts an arc if the endpoints of the arc lie on the sides of the angle and all points of the arc except the endpoints lie in the interior of the angle;

3. Secant ray: a ray that lies on a secant line and contains both points of intersection with the circle; and

4. Inscribed angle: an angle with sides containing the endpoints of an arc and with a vertex that is a point of the arc other than an endpoint of the arc.

The sum of the fractions 1/5, 1/7 and 3/21 is 17/35. This was achieved by finding the least common denominator (LCD), converting the fractions to have the LCD, adding them, and then simplifying the result.

To add or subtract fractions, it's essential to find the least common denominator (LCD). The LCD in this case would be the least common multiple (LCM) of 5, 7, and 21, which is 105. Once we have the LCD, we can rewrite the fractions as an equivalent fraction with the LCD as the denominator:

Now all the fractions have the same denominator, and we can combine the numerators: 21/105 + 15/105 + 15/105 = 51/105. However, this can be simplified to 17/35 by dividing both numerator and denominator by 3.

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{3}{4}[/tex] x - 9 ← is in slope- intercept form

with slope m = [tex]\frac{3}{4}[/tex]

• Parallel lines have equal slopes, hence

y = [tex]\frac{3}{4}[/tex] x + c ← is the partial equation of the parallel line.

To find c substitute (- 8, - 18) into the partial equation

- 18 = - 6 + c ⇒ c = - 18 + 6 = - 12

y = [tex]\frac{3}{4}[/tex] x - 12 ← equation of parallel line

Answer:

Step-by-step explanation:

The equation of a linear function in point-slope form is y – y1 = m(x – x1)

The point is A (x1 , y1)  

the slope is : m     the line that is parallel to the given line so : m = 3/4

passes through the given point (-8 -18)

so :  x1 = - 8   and y1 = -18

Answer:

(a) 38 inches (b) 374 inches (c) 3564 inches (d) 6273767 square inches

Step-by-step explanation:

a) 2 ft 5 inches + 9 inches

Convert to inches

1 feet = 12 inches

2 feet = 12 x 2 inches = 24 inches

24 inches + 5 inches + 9 inches = 38 inches

b) 4 yards 8 inches + 6 yards 6 inches

Convert to inches

1 yard = 36 inches

4 yards = 36 x 4 = 144 inches

144 inches + 8 inches = 152 inches

6 yards = 36 x 6 = 216 inches

216 inches + 6 inches = 222 inches

152 inches + 222 inches = 374 inches

c) 29 yard 2 feet 11 inches + 55 yard 1 feet 10 inches + 13 yard 1 feet 3 inches

Convert to inches

29 yard 2 feet 11 inches

1 yard =  36 inches

29 yards = 36 x 29 = 1044 inches

1 feet = 12 inches

2 feet = 12 x 2 = 24 inches

1044 + 24 + 11 = 1079 inches

55 yard 1 feet 10 inches

1 yard = 36 inches

55 yards = 26 x 55 = 1980 inches

1 feet = 12 inches

1980 + 12 + 10 = 2002 inches

13 yard 1 feet 3 inches

1 yard = 36 inches

13 yards = 13 x 36 = 468 inches

1 feet = 12 inches

468 + 12 + 3 = 483 inches

1079 + 2002 + 483 = 3564 inches

d) 4,839 sq yard 8 sq feet 139 sq inches + 7 sq feet 124 sq inches

Convert to square inches

4,839 sq yard 8 sq feet 139 sq inches

1 square yard = 1296 square inches

4839 x 1296 = 6271344 square inches

1 square feet = 144 square inches

8 x 144 = 1152

6271344 + 1152 = 6272635 square inches

7 sq feet 124 sq inches

7 x 144 = 1008

1008 + 124 = 1132 square inches

1132 + 6272635 = 6273767 square inches

WHAT WE KNOW  Levi reads 280 words in 2 minutes. We need to find out how many words he can read in 5 minutes

To find out how many words Levi can read in 5 minutes, it will first be easier to find out how many words Levi can read in 1 minute. To find this, we will divide 280 by 2 and that will give us the number of words per minute.

Next, once we divide we will get a quotient of 140.

Finally, we take 140 and multiply it by 5 and we get a product of 700

Therefore, Levi reads 700 words in 5 minutes

Answer:

Option C is correct.

Step-by-step explanation:

Let x be the original width

then x+2 will be the length (consecutive odd integer)

if length is increased by 5 feet , length will be: (x+2)+5 = x+7

Area = 60 square ft.

Area = length * width

60 = (x+7) *x

60 = x^2 +7x

Rearranging

x^2 + 7x -60 = 0

Solving quadratic equation to find the value of x

using Quadratic formula

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

a=1, b =7, c=-60

[tex]x=\frac{-7\pm\sqrt{(7)^2-4(1)(-60)}}{2(1)}\\x=\frac{-7\pm\sqrt{49+240}}{2}\\x=\frac{-7\pm\sqrt{289}}{2}\\x=\frac{-7\pm17}{2}\\x=5 \,\, and \,\, x = -12\\[/tex]

Since width can be positive so x=5

length of original rectangle = x+2 = 5+2 =7

Area of original rectangle = Length * Width

Area of original rectangle = 5 * 7

Area of original rectangle = 35 ft^2

So, Option C is correct.

Final answer:

The width of the original rectangle is 5 feet, and the length is 7 feet, making the area 35 square feet. We determined this by setting up an equation for the area of the enlarged rectangle and solving for the odd integer width.

Explanation:

We are given that a rectangle has dimensions of consecutive odd integers and if the length is increased by 5 feet, the resulting area is 60 square feet. Let's denote the width as w feet (an odd integer) and the length as w + 2 feet (the next consecutive odd integer), since consecutive odd integers are two units apart.

After increasing the length by 5 feet, the new dimensions are w feet and w + 7 feet. The area can be calculated as the product of these dimensions:

w × (w + 7) = 60

Solving this quadratic equation: w² + 7w = 60

Subtracting 60 from both sides gives: w² + 7w - 60 = 0. Factoring this, we get: (w + 12)(w - 5) = 0

Considering the positive value that fits the condition of being an odd integer, we find that w = 5 feet. This makes the width 5 feet and the length 7 feet (5 + 2) for the original rectangle.

Thus, the area of the original rectangle is 5 feet × 7 feet = 35 square feet.

Therefore, the correct answer is C. 35 ft².

Answer:

39

Step-by-step explanation:

The short answer is 39.

Every triangle has 180 degrees. There are no exceptions to this rule.

Since a triangle has 3 angles, all three together must add up to 180o

A right angle = 90 degrees always.

You are given 51 degrees as your second angle

The third one is x

x + 51 + 90 = 180                   Total of three angles must be 180

x + 141 = 180                           The left has been added to give 141

x = 180 - 141                            Subtract 141 from both sides

x = 39                                     The third angle = 39

[tex]\displaystyle \frac{25}{2}\pi \approx 39.3[/tex] inches.

Step-by-step explanation:

The question gives the central angle and radius of an arc and is asking for the length.

An arc is part of a circle. What is the circumference of a circle with a radius 15 inches?

[tex]\text{Circumference} = \pi \times \text{Diameter} = 2\pi \times \text{Radius} = 30\pi[/tex] inches.

However, this wiper traveled only a fraction of the circle. A full circle is [tex]360^{\circ}[/tex]. The central angle of this arc is only [tex]150^{\circ}[/tex]. As a result,

[tex]\displaystyle \frac{\text{Length of this arc}}{\text{Circumference of the circle}} = \frac{150^{\circ}}{360^{\circ}} = \frac{5}{12}[/tex].

The length of the arc will thus be

[tex]\displaystyle \frac{5}{12} \times 30\pi = \frac{25}{2}\pi \approx 39.3[/tex].

In other words, the windshield wiper traveled approximately 39.3 inches.

To find the distance traveled by the end of the windshield wiper making a 150° arc, calculate the circumference of the circle swept and apply the formula to determine the distance traveled.

Distance traveled by the end of the windshield wiper:

Calculate the circumference of the circle swept by the windshield wiper: Circumference = 2πr = 2π(15 in).

Convert the circumference to inches: Multiply the circumference by the angle traversed (150°/360°) to find the distance traveled by the wiper's end.

Distance traveled = Circumference x (150/360) = 15π/2 inches or 23.56 inches.
