Answer:
History test
Step-by-step explanation:
28 divided by 40 is 0.7 which equals 70 percent.
39 divided by 60 is 65 percent .
Answer:
Phil did better on his History test.
Step-by-step explanation:
In the history test, he scored a 28/40. There are many ways to do this, but here is my way. Convert this to decimal to make comparison easy.
28/40 = 0.7
In the Geography test, he scored 39/60. Convert this to decimal as well.
39/60 = 0.65.
Since 0.7 > 0.65, Phil did better on his history test.

Your classmate says that the solutions to the given inequality are x > -2. Look carefully at the work. Should your friend have reversed the inequality symbol? Explain. Then solve the inequality correctly.
Please don't send those annoying files, I'm not trying to get a virus on my laptop. Please, if you can, just write out the steps/answer(s).
Answer:
x < -2 (No, he shouldn't have reversed the inequality symbol).
Step-by-step explanation:
Given the algebraic expression;
19 - 2(1 - x) < 13
Opening up the bracket, we have;
19 + (-2*1) + (-2*-x) < 13
19 + (-2) + (2x) < 13
19 - 2 + 2x < 13
17 + 2x < 13
Rearranging the equation, we have;
2x < 13 - 17
2x < -4
Dividing both sides by 2, we have;
x < -2
Hence, your friend shouldn't have reversed the inequality symbol (sign).
Note: you should only flip the inequality symbol (sign) when you're dividing by a negative number such as -2.
For example, if we had re-arranged the equation as;
17 - 13 < -2x
4 < -2x
Dividing both sides by -2, we have;
4 > x

a phone is 35 percent off which is now worth 78 pounds what was the original price
Answer:
120 pounds
Step-by-step explanation:
65% of y= 78 pounds
[tex]\frac{65}{100}[/tex] × y = 78 pounds
65y = 78 × 100=7800
y= 7800/65= 120 pounds
You would like to lease a car worth $52,696 for a three-year period. The leasing company told you that after three years, the car would have a residual value of $39,826. What percentage represents the residual value of your leased car?
Answer: 75.58%
Step-by-step explanation:
Since we are given the information that the worth of the car will be leased for $52696 and the residual value will be $39826, the percentage that represents the residual value of the leased car will be:
= (39826 / 52696) × 100
= 0.7558 × 100
= 75.58%

Dave jarred 12 liters of jam after 6 days. How much jam did Dave jar if he spent 9 days making jam?
Answer:
18 liters of jam after 9 days
Step-by-step explanation:
12 liters = 6 days
12 liters ÷ 6 days = 2 liters per day
2 liters per day x 9 days = 18 liters of jam in 9 days
Dave jarred 18 liters of jam in 9 days

the melting point of ice + common salt =
Answer:
Step-by-step explanation:
Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius). When you add salt, that temperature drops: A 10-percent salt solution freezes at 20 °F (-6 °C), and a 20-percent solution freezes at 2 °F (-16 °C). On a roadway, this means that if you sprinkle salt on the ice, you can melt it.

Fernanda is filling a cylindrical pot with cans of vegetable soup. The pot has a diameter of 15 in. and a height of 11 in. The soup can has a diameter of 3 in. and a height of 6 in. How many cans of soup will it take to fill the pot? Round to the nearest can.
Answer:
45 cans
Step-by-step explanation:
To find the volume of a cylinder, we need to find the area of the cross section, which in this case is π(radius)², and multiply it with the height of the cylinder
This means the pot has a volume of:
- pot has radius of 7.5in. as diameter is 2 x radius
π x (15/2)² x 11 = 618.75π in.³
The soup can has a volume of:
- soup can has radius of 1.5in. as diameter is 2 x radius
π x (3/2))² x 6 = 13.5π in.³
Divide the volume of the pot by the volume of the can to get how many cans of soup will it take to fill the pot:
618.75π in.³ ÷ 13.5π in.³ = 45.833... cans
The question states you need to round to nearest can which would be 45 cans, but personally, I thought you would always round up as 45 cans won't fill up the whole pot, but it's up to the question.

Abel is 12 years old and Gino is 8. They share 15 apples in the ratio of their ages. How many does each get?
Answer:
Abel gets 9 apples while Gino gets 6 apples.
Step-by-step explanation:
Total age = 20 (Abel's age =12 + Gino's age =8)
Abel's share =
[tex] \frac{12}{20} \times \frac{15}{1 } = 9[/tex]
Gino's share =
[tex] \frac{8}{20} \times \frac{15}{1} = 6[/tex]
Simplify: √54 + √486 + √24
Answer:
14√6.
Step-by-step explanation:
√54 = √9√6 = 3√6
√486 = √81 √6 = 9√6.
√24 = √4√6 = 2√6.
So √54 + √486 + √24
= 3√6 + 9√6 + 2√6
= 14√6.
Una recta con pendiente -2 ´pasa por el punto P(5, -1). La abscisa del punto Q que está en esa recta es 1. Encuentre la ordenada de Q.
Answer:
La ordenada de Q es 7.
Step-by-step explanation:
La ecuación de una recta es:
y = a*x + b
donde a es la pendiente y b es la ordenada al origen.
Para este problema, sabemos que la pendiente es -2
Entonces:
a = -2
y = -2*x + b
También sabemos que esta recta pasa por el punto (5, -1)
Esto significa que cuando evaluamos la ecuación en x = 5, y toma el valor y = -1
Si reemplazamos esos valores en la ecuación, obtenemos:
-1 = -2*5 + b
-1 = -10 + b
-1 + 10 = b
9 = b
Entonces la ecuación de la recta es:
y = -2*x + 9
Sabemos que el punto Q está en la línea, y la abscisa de este punto es 1.
Entonces este punto es Q (1, k)
donde k es la ordenada de este punto.
Porque nuestra línea también pasa por este punto, podemos concluir que cuando x = 1, y = k
Reemplazando eso en la ecuación tenemos:
k = -2*1 + 9 = -2 + 9 = 7
k = 7
La ordenada de Q es 7.

What is the length of a diagonal of a cube with a side length of 3 cm? O 18 cm 0 27 cm 182 cm OW38 cm
Answer:
18 cm
Step-by-step explanation:
please mark this answer as brainliest
Answer:
18 cm
Step-by-step explanation:
The main diagonal of any cube can be found by multiplying the length of one side by the square root of 3.
Given: side x = 3 cm
Use the diagonal formula,
Diagonal of cube = 3–√x
Diagonal of cube = 3–√ × 3
We know that the value of √3 is 1.734
Therefore, the diagonal of a cube = 1.734 (3)
Diagonal of cube = 5.20 cm
