Answer:

13.2m

Step-by-step explanation:

the initial vertical velocity of the ball is 25 sin 40 = 16.1m/s

since gravity reduces the vertical velocity of objects by 9.8m/s/s, this ball will reach max altitude in a time of

time = 16.1m/s / 9.8m/s/s = 1.6s

the max height is equivalent to the height an object will fall in 1.6s, so we have

height =1/2 g t^2 = 1/2 x 9.8m/s/s x (1.6s)^2 = 13.2m

Answer:

28.5*40=1140

1140*52=59280

So the librarian makes an earning of $59,280 per year

Answer: $59,280

Step-by-step explanation:

multiply $28.5 by 40 to get how much she makes in a week= $1,140 multiply that by 52 because there are 52 weeks in a year and you get $59,280

Answer:

The original cost of the butter cup was $91.

Step-by-step explanation:

Let x be the original price of the kitten butter cup.

Since Susan pays five out of seven of the original cos plus a fee of $24, the total amount she paid is 5x/7 + 24.

Now, this total amount equal the $89 she paid for the kitten butter cup. So,

5x/7 + 24 = 89.

We now solve this equation to find the original cost of the kitten butter cup.

So,

5x/7 + 24 = 89

Collecting like terms, we have

5x/7 = 89 - 24

5x/7 = 65

multiplying both sides by 7, we have

5x = 65 × 7

dividing both sides by 5, we have

x = 65 × 7 ÷ 5

x = 91

So the original cost of the butter cup was $91.

Answer:

24 quarts

Step-by-step explanation:

Jasper Green mix equals 4 quarts of green paint with 2/3 cups of black paint.

4 quarts = 16 cups

Find factor::

4/1 ÷ 2/3 = 4/1 × 3/2 = 6

Multiply

Green                                Black

4                                         2/3 (6)

x                                            4 (6)

=24 qts of green paint

To make jasper green, 24 quarts of green paint will be needed.

Given that,
To make a shade of paint called jasper green, mix 4 quarts of green paint with 2/3 cups of black paint.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

here,
Let the number of quarts need be x,
taking ratios,
4/[2/3] = x / 4
x = 6 × 4
x = 24

Thus, to make jasper green, 24 quarts of green paint will be needed.

Step-by-step explanation:

Answer: The perimeter of rectangle M'N'O'P' =54 cm

Step-by-step explanation:

When we dilated a figure , then the image is the similar figure them the original.

For similar figures,

[tex]\dfrac{\text{Area of original figure}}{\text{Area of image}}=\dfrac{(\text{perimeter of original figure})^2}{(\text{perimeter of image})^2}[/tex]

As per given, Rectangle MNOP has a perimeter of 18 cm and an area of 14 cm².

Area of M'N'O'P' =  126 cm²

then,

[tex]\dfrac{14}{126}=\dfrac{18^2}{(\text{(perimeter of M'N'O'P'})^2}\\\\\Rightarrow\ \text{(perimeter of M'N'O'P'})^2=\dfrac{324}{14}\times126\\\\\Rightarrow\ \text{(perimeter of M'N'O'P'})^2=2916\\\\\Rightarrow\ \text{perimeter of M'N'O'P'}=\sqrt{2916}=54[/tex]

Hence, the perimeter of rectangle M'N'O'P' =54 cm

Answer:

$1.44

Step-by-step explanation:

$11.52 (divided by) 8 = $1.44

The cost of each candy necklace will be $1.44 per candy necklace.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Rosa spent $11.52 on 8 candy necklaces for each of her two friends.

Then the cost of each candy necklace will be given by dividing $11.52 by 8.

⇒ $11.52 / 8

⇒ $1.44 per candy necklace

The cost of each candy necklace will be $1.44 per candy necklace.

Answer:

y=(x+1)^2-7

Step-by-step explanation:

y=x^2+2x-6=x^2+2x+1-7

y=(x^2+2*1*x+1^2)-7

y=(x+1)^2-7

vertex form equation is y=a(x-h)^2+k

of equation y=ax^2+by+c

so a is 1

h is -1 because (x+1)=(x-(-1))

k is -7

Step-by-step explanation

Rate of change is the slope, [tex]\frac{Y}{X}[/tex]

The distance from our y values which are -1 and 5 is 6.

The distance from our x values which 4 and 7 is 3.

Since its [tex]\frac{Y}{X}[/tex] The 6 would be over the 3 as 6/3 which simplifies to 2 or 2/1.

Thus, 2/9 is the simplified fraction for 8/36 by using the GCD or HCF method. Thus, 2/9 is the simplified fraction for 8/36 by using the prime factorization method.

Step-by-step explanation:

The two equivalent fractions for the given fraction are 4/18 and 2/9.

The given fraction is 8/36.

The equivalent fraction will be obtained by dividing or multiplying both the numerator and denominator of the fraction by same number.

Here, divide both the numerator and denominator by 2, we get

(8÷2)/(36÷2)

= 4/18

Again divide both the numerator and denominator by 2, we get

(4÷2)/(18÷2)

= 2/9

Therefore, the two equivalent fractions for the given fraction are 4/18 and 2/9.

glenn has 2 times as many hats so, h2 and then he has 4 less so -4

Answer:

It would be the first, 2h-4

Step-by-step explanation:

H stands for hats

We don’t have the numbers to solve, which we don’t need for this problem. But if we were solving we would multiply the amount of hats Mia has by two (2h). It says Glenn has four less than that, so you would then subtract four from whatever 2h would equal.

Answer:

a) The Metra will go 90 miles in 6 hours

b) It will take Amtrak 8 hours to travel 160 miles.

Step-by-step explanation:

From the question,

Metra travels 30 miles in 2 hours

a) To determine how far the Metra will go in 6 hours,

Let how far the Metra will go in 6 hours be x

Then,

If Metra goes 30 miles in 2 hours

Then, Metra will go x miles in 6 hours

x = (30 × 6)/2 miles = 90 miles

Hence, the Metra will go 90 miles in 6 hours.

b) To determine how long it will take Amtrak to travel 160 miles,

Let how long it will take Amtrak to travel 160 miles be y

From the question,

Amtrak travels 80 miles in 4 hours

Now,

If Amtrak travels 80 miles in 4 hours

Then, Amtrak will travel 160 miles in y hours

y = (160 × 4)/80 hours = 8 hours

Hence, it will take Amtrak 8 hours to travel 160 miles.
