Smoothies weren't cutting it so we went to Red Robin to order a burger. Our bill was $5.79. Avon has a 5.25% tax and our
waitress earned a 15% tip. What was the total bill?
Answer:
$6.96
Step-by-step explanation:
5.25% of 5.79
5.79 × 5.25/100 = $0.303975 or $0.30
15% of 5.79
5.79 × 15/100 = $0.8685 or $0.87
total
$5.79 + $0.30 + $0.87 = $6.96

The school library has 2,469 books. Two-thirds of them are paperbacks. How many
books are paperbacks?
Answer:
2469 x 2/3= 1646
personally, I solve it by dividing the 2469 by 3 to get 1/3.
2469/3= 823
then, double it to get 2/3.
823x2= 1646
What is 9 x 2/3 as a fraction.
The expression 9x2/3 can be written in fraction form as, 18/3
What is a fraction?Fraction is a mathematical term, which represents the portion or sub-parts of the whole thing. Basically, It has two parts: numerator and denominator.
Numerator is a number which lies on the top side, it indicates the number of equal parts taken and denominator is on the bottom side, it indicates the equal parts of the whole number.
9 times 2/3 can be calculated by first converting 9 to a fraction and then multiplying that fraction by 2/3. To convert 9 to a fraction, we write it over 9/1 x 2/3
Next, we multiply the two fractions by multiplying the numerators (the top numbers) together and the denominators (the bottom numbers) together:
⇒ (9/1) x (2/3)
⇒ (9 x 2) / (1 x 3)
⇒ 18/3
So, 9 times 2/3 as a fraction is 18/3.

May someone help me with this. I have to use the Pythagorean theorem for this problem. May you show steps too?
Answer:
the missing side value is 6.7.
Step-by-step explanation:
so the Pythagorean theorem is a^2+b^2=c^2, but since we are missing the b slide the equation now is 7^2-2^2=b^2. now you may not understand why we are missing the b side. so in the Pythagorean theorem, the a and b slides dont really matter, as long as the c side is the hypotenuse, or the longest slide in a triangle. so 7squared is 49, 2 squared is 4, so 49-4= 45, but its 45squared because the equation is c^2-a^2=b^2 so now we know that 45 is b squared, we just have to square root 45, to get about 6.7.
PLISS ANSWER :C DONT ANSWER IF YDK THAnKSSS
*also pls look at both images :)*
Answer:
First image: (6, -1)
2nd image: y = 63
Explanation:
1)
2x + y = 11
1/2x - 5y = 8
y = -2x + 11
1/2x - 5(-2x + 11) = 8
1/2x + 10x - 55 = 8
10.5x - 55 = 8
10.5x = 63
x = 6
2x + y = 11
2(6) + y = 11
12 + y = 11
y = -1
(x , y) = (6, -1)
2)
1/4(8y - 4.8) = 2 (0.9y + 5.4) + 3/5
2y - 1.2 = 1.8y + 10.8 + 0.6
0.2y - 1.2 = 11.4
0.2y = 12.6
y = 63

3x−4y+4y=6+4y
3x/3=4y+6/3
x=4/3y+2
7x-6y=9
7(4 /3 y+2)−6y=9
10 /3 y+14=9
10 /3 y+14+−14=9+−14
10 /3 y /10 /3 = −5 /10 /3
y= −3 /2
x= 4/ 3 y+2
x= 4 /3 ( −3 /2 )+2

x=0 and y= −3 /2
The hypotenuse of a right triangle measures 19 cm and one of its legs measures 2 cm.
Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
cm
Submit Answer
attempt 1 out of 2
Answer:
18.9 cm
Step-by-step explanation:
Pythagorean Theorem --> A² + B² = C²
2² + B² = 19²
4 + B² = 361
B² = 357
√357 --> 18.89 --> 18.9
The measure of the other leg to the nearest tenth will be 18.9 centimeters.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The hypotenuse of a right triangle measures 19 cm and one of its legs measures 2 cm.
Let the other leg be 'x'. Then the measure of the other leg will be given as,
19² = x² + 2²
361 = x² + 4
x² = 361 - 4
x² = 357
Take square root on both sides, then we have
x = √357
x = 18.8944
x ≈ 18.9 cm
The measure of the other leg to the nearest tenth will be 18.9 centimeters.

The dot plot shows a random sample of the number of fish caught and released by 30 participants during a two-day fishing derby. Two dot plots show the number of fish caught on days 1 and 2. The dot plot for day 1 has dots as follows: 3 above 1, 6 above 2, 6 above 3, 6 above 4, 6 above 6, and 3 above 6. The dot plot for day 2 has dots as follows: 3 above 1, 3 above 2, 4 above 3, 6 above 4, 7 above 5, and 7 above 6. Use the mean value of each data set to make an inference about the number of fish caught each day. On average, most participants caught and released 5 or more fish. More participants caught 6 fish than any other number. The same participants who caught and released 1 fish the first day caught and released 1 fish the second day. On average, participants caught and released more fish on Day 2.

Jake’s mom filled a 2-liter container with juice. Then Jake poured 2 glasses of juice. Each glass had exactly 400 milliliters of juice. How many liters of juice remain in the container?
12.00 liters
1.2 liters
Answer:
1.2
Step-by-step explanation:
1 liter = 1000 milliliters
if there’s two liters, that’s 2000 milliliters. the mom then poured 2 glasses each with 400 milliliters, or 800 milliliters in total. 2000 - 800 = 1200. 1200 milliliters converted into liters = 1.2 liters.
Answer:
1.2 liters
