Answers
Answer:
t = 2 s and t = 4 s
Step-by-step explanation:
A ball is projected upward from ground level. After t seconds, it’s height in feet is a function defined by,
[tex]f (t) = -16t^2 + 96t[/tex]
We need to find in how many seconds will the rocket be at a height of 128 ft above the ground.
It means,
[tex]128= -16t^2 + 96t\\\\-16t^2+96t-128=0\\\\16(-t^2+6t-8)=0\\\\(-t^2+6t-8)=0\\\\-t^2+4t+2t-8=0\\\\t(-t+4)-2(-t+4)=0\\\\(t-2)=0\ and\ (-t+4)=0\\\\t=2\ and\ t=4[/tex]
So, it will be at a height of 128 feet at 2 second and 4 second.

Penny, Amjit and James share some money in the ratio 3 : 6 : 4
Amjit gets $28 more than James.
Work out the amount of money that Penny gets.
Answers
Answer:
$42
Step-by-step explanation:
Let the amounts received by Penny, Amjit and James be 3x, 6x and 4x respectively.
According to the given information:
Amount received by Amjit = Amount received by James + 28
So,
6x = 4x + 28
6x - 4x = 28
2x = 28
x = 28/2
x = 14
Amount of money received by Penny = 3x = 3*14 = $42

Student’s Answer Key Ch.2 Grammar Advantage Eric Nelson & George Yule © 2019 Student’s Answer Key, Chapter 2, Sentence structure, Grammar Advantage
For most exercises, this key does not include even-numbered items.
■ Exercise 1 Read the passage. Based on what you already know, underline the verbs.
The Marshmallow Experiment
Imagine that you are seven years old. You are participating in an experiment. A researcher greets you and shows you into a small room. In the room there is a marshmallow. The marshmallow is for you, but here is the interesting part: The researcher tells you that he is going to leave you alone in the room for a while. You can eat the marshmallow right away, or you can wait until he gets back. If you wait until he gets back, you will get a second marshmallow.
What do you do? Do you eat the marshmallow right away?
An experiment like this, known informally as the marshmallow experiment, was conducted decades ago at Stanford University. It turned out that some children ate the marshmallow right away, while others were able to wait. In other words, some sought instant self-gratification, and some delayed it.
Years later, the researchers followed up on the participants. They found that the children who delayed self-gratification were in general more successful than those who ate the marshmallow right away. By a variety of measures, including SAT scores, they appeared to be more competent.
Common sense tells us that the ability to delay self-gratification is a mark of maturity. The marshmallow experiment provides evidence that it may also correlate with success in life.
Notes:
- Many of these verb phrases consist of an auxiliary verb and a main verb. So, for example, “are participating” and “do...eat” are considered verb phrases.
- “is going to leave”: If we consder “is going to” a kind of auxiliary verb, then this is a verb phrase, just like “will leave.”
- “known as...”: If you underlined “known,” that’s fine. It is a verb. It is a nonfinite verb, unlike the other underlined verbs and verb phrases. (See Chapter 4.)
■ Exercise 2 Underline the complete subjects in the sentences below, and double- underline the verbs that go with them. Identifying the subject means identifying the main word of the subject and the parts that modify it. (In the first sentence, the main word is in boldface.) When you underline the verb, include both auxiliary verbs and main verbs (as in the first sentence, with was...used).
In the 1960s and 70s, the term “generation gap” was often used to refer to the differences between young people in the U.S. and their parents’ generation. Many young people felt distant from their parents because of differences in ideas about politics, social issues, and popular culture. Since then, conflicts between generations have diminished in many ways. Child-rearing experts in the late 20th century encouraged parents to be like friends to their children. Thanks to technology, young people and their parents are able to contact each other easily at any time. On any college campus, the students you see texting or talking on cell phones are often communicating with Mom or Dad. Fifty years ago, closeness of this kind was less

If 20 quarts of 15% garlic is mixed with 45 quarts 80% garlic, what percent garlic is the new mixture?
Answers
Answer:
60%
Step-by-step explanation:
If 20 quarts of 15% garlic is mixed with 45 quarts 80% garlic, what percent garlic is the new mixture?
Let us represent:
15% garlic = x
80% garlic = y
Total quarts of the new mixture =
20 + 45 = 65 quarts
Hence:
15% × 20 + 80% × 45 quarts = 65quarts(x%)
3 + 36 = 65 × x%
39 = 65 × x%
x % = 39/65
x% = 0.6
Converting to decimal
= 0.6 × 100
= 60%
The Percent of the new garlic mixture = 60%

Answers
Given:
The table of values for Fallon's earnings in terms of Donald's earnings.
To find:
The equation that best represents Fallon's earnings in terms of Donald's earnings.
Solution:
In the given table the x-values are increasing by 5 units and y values increasing by 5 units. It means the rate of change of y with respect to x is constant and the table represents a linear function.
If the graph of a linear function passes through two points, then the equation of linear function is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Consider any two points from the table. Let the two points are (38,45) and (43, 50). Then, the equation is
[tex]y-45=\dfrac{50-45}{43-38}(x-38)[/tex]
[tex]y-45=\dfrac{5}{5}(x-38)[/tex]
[tex]y-45=1(x-38)[/tex]
[tex]y-45=x-38[/tex]
Adding 45 on both sides, we get
[tex]y=x-38+45[/tex]
[tex]y=x+7[/tex]
Therefore, the correct option is A.
Your teacher has a bag of candy. She gives you 2/3 of the candy in the bag, and your friend 1/8 of it. How much more candy than your friend did you get?
Answers
Answer: 13/24
Step-by-step explanation:
Since the teacher gives me 2/3 of the candy in the bag, and gives my friend 1/8 of it, the amount of candy that I got more than my friend will be gotten by subtracting 1/8 from 2/3. This will be:
= 2/3 - 1/8
The lowest common multiple of 3 and 8 is 24, therefore we can change the numerator if the fractions toma common base.
= 2/3 - 1/8
= 16/24 - 3/24
= 13/24

Two right triangles are similar. The legs of the smaller triangle have lengths of 15 and 20. The scale factor is 1:2. Find the length of the hypotenuse of the larger triangle.
Answers
Answer:
If the scale factor of corresponding sides is 1:2 then the hypotenuse if 50 units.
Step-by-step explanation:
The length of the hypotenuse of the larger triangle is 50 units.
What is the scale factor ?Scale factor is a mathematical term, which we use to scale 2-dimensional and 3-dimensional shapes.
For example, Two spheres look similar but could have different radii.
Let's denote the length of the hypotenuse of the smaller triangle as c, and the length of the hypotenuse of the larger triangle as C. Then we can write:
C/c = 2/1
Multiplying both sides by c, we get:
C = 2c
We can use the Pythagorean theorem to find the length of the hypotenuse c of the smaller triangle:
c² = 15² + 20²
c² = 225 + 400
c² = 625
c = 25
Substituting c = 25 in the equation above, we get:
C = 2(25)
C = 50
Therefore, the length of the hypotenuse of the larger triangle is 50 units.

Answers
Answer:
Let andre score be x points.
then Diego's score will be (x-9) points.
Noah's points=2(x-9) points
the equation is 2(x-9) = 10
dividing both sides by 2,
2(x-9)/2 =. 10/2
x-9= 5
adding 9 both sides,
x-9+9= 5+9
x=14.
Step-by-step explanation:
Answer:
Andre score 14 points
Step-by-step explanation:
noah = 2*diego
diego = andre - 9
given noah = 10
noah = 2*Diego
10 = 2*Diego
Diego = 5
diego = andre - 9
5 = andre - 9
andre = 9 + 5
Andre = 14
Si una persona aprovecha un descuento del 20% y paga 60.000 pesos por una camisa,¿Cuál era el precio de la camisa sin el descuento?
Answers
Answer:
the price of the shirt without discount is 75,000 pesos
Step-by-step explanation:
The computation of the price of the shirt without discount as follows:
There is a discount of 20%
And the person pays 60,000 pesos after considering the discount
So, the price without discount is
= 60,000 pesos ÷ 0.80
= 75,000 pesos
hence, the price of the shirt without discount is 75,000 pesos
