the town of lantana needs $14,000 for a new playground. lantana elementary school raised $5358 lantana middle school raised $2834 and lantana high school raised 4132.
about how much more money do they need to raise?

Answers

Total money needed = $14,000
Total money collected = $5358+$2834+4132 = $12324

Additional money needed = Total money - Money collected

=> $14,000 - $12,324
=> $1,676

So they need $1676 more money to be collected

Answer:  [tex]6y^3 + 17y^2 + 22y + 15[/tex]

Step-by-step explanation:

Here, the given expression, [tex](2y+3). (3y^2+4y+5)[/tex]

By applying distribution property in second bracket,

=  [tex]3y^2(2y+3)+4y(2y+3)+5(2y+3)[/tex]

=  [tex]6y^3+9y^2+8y^2 +12y+10y+15[/tex] ( again by applying distributive property)

= [tex]6y^3+17y^2 +22y+15[/tex]  ( by adding like terms)

Thus, [tex](2y+3). (3y^2+4y+5)[/tex]= [tex]6y^3+17y^2 +22y+15[/tex]

Drawing a vowel from letter tiles that spell out MATHEMATICS.

Answers

Well because the question isn’t specified, I can only assume that this is a probability question?
Answer: There are 4 vowels out of the 11 total letters in the word MATHEMATICS. 4/11 is 0.3636... or approximately 36%.
This means that there is a 36% chance of drawing a vowel from the word MATHEMATICS.

Final answer:

Explanation of drawing a vowel from the letters spelling MATHEMATICS focusing on vowels A, E, and I.

Explanation:

Vowels are fundamental in the English language. When drawing a vowel from the letters that spell out MATHEMATICS, we identify the vowels to be A, E, I. Therefore, drawing a vowel from these letters could result in A, E, or I.

The cost of attendance at State College is $19,500 for the first year. Devise a periodic savings plan that will allow you to make small deposits for 5 years at a simple interest rate of 1.5% and save enough to pay for the first year at the college.

I only want verified answers
pls dont answer if you dont know or you are not an expert

Answers

simple interest rate for one year = 1.5%
simple interest rate over 5 years = 1.5 x 5 = 7.5%

100% + 7.5% = 107.5%
107.5% = $19500
1% = 181.3953
100% = $18140.50

He needs to put in $18140.50 so that he can get $19,500 at the end of 5 years.

so 2.5 os to 50, aka 2.5:50
divide each side by 2.5 to get the answer.
if you dont have a calculator, divide each side by 5 to get .5:10, multiply by 2 to get 1:20
To solve this problem simply set up a fraction of a ratio with the 2 numbers.

Then make a new fraction and place the unknown as the variable, here it is x minutes

2.5 miles/50 minutes = 1 mile/ x minutes

4 spoons and 3 forks cost $15 4 spoons and 1 fork cost $13 how many do the forks cost?

Answers

Let's say that s=spoons and f=forks. 

According to this, we can say that:

{4s+3f=15
{4s+f=13

This is a system. 

We can then use elimination to solve and isolate the variable:
(4s-3f=15)
- (4s+f=13)

We can then subtract and conclude that:
-4f=2
-f=1/2
f=-1/2

A suit is on sale for $272 , which is 15% less than the regular price. What is the regular price?

Answers

To find the original price of a discounted object, we must use the following equation...

Original Price = Discounted Price * (Discount % + 1)
Original Price = 272*(1 + 0.15) = $312.80

Therefore, the original price is $312.80

A snail moves 1/40 of a mile in 3/4 of an hour. If the snail continues at this pace, how far, in miles, does it move in one hour?
The answer is .03 or 1/30 but, Idk how to explain my answer.

Answers

1/40 ÷ 3/4 = 1/40 ÷ 4/3 = 4/120 = 1/30

A snail moves 1/40 of a mile in 3/4 of an hour. If the snail continues at this pace, how far, in miles, does it move in one hour?

In [tex] \frac{3}{4} [/tex] hour snail moves [tex] \frac{1}{40} [/tex]miles

[tex] \frac{3}{4} hour = \frac{1}{40} [/tex] miles

Let us multiply by 4 on both sides, so that we can get the distance to be traveled in 1 hour.

So, [tex] \frac{3*4}{4} hour=\frac{1*4}{40} [/tex] miles

[tex] \frac{3*1}{1} hour=\frac{4}{40} [/tex] miles

Now to get distance in 1 hour, Let us divide by 3 on both sides

[tex] \frac{3}{3} hour=\frac{1}{10*3} [/tex] miles

[tex] \frac{1}{1} hour=\frac{1}{30} [/tex] miles

In 1 hour, the snail travels [tex] \frac{1}{30} [/tex]miles

How is the following decimal number read?

28.9


A. Twenty and eight-nine tenths

B. Twenty-eight and nine hundredths

C. Twenty-eight and nine tenths

D. Twenty-eight nine

Answers

Answer:
C) twenty-eight and nine tenths

Explanation:
We have two parts here, the whole number and the decimal part.

1- for the whole number, it is read normally as counting numbers. Therefore, 28 is read as twenty-eight
2- for the decimal part, it is read based on the place-value of the number. We know that the first number after the decimal point is in the tenth position. This means that 0.9 is read as nine tenths

Combining the two, we would conclude that 28.9 is read as twenty-eight and nine tenths

Hope this helps :)

Answer:

C. Twenty-eight and nine tenths.

Step-by-step explanation:  

We have been given a decimal number [tex]28.9[/tex]. We are asked to choose the correct option that represents how to read our given decimal number.

Upon looking at our given decimal number we can see that it has one digit at tenth place that is 9, which represents that our number has 9 tenths.  

The two digits before decimal are 2 (tens place) and 8 (ones place). These digits make 28.

Therefore, the given decimal number could be read as twenty-eight and nine tenths and option C is the correct choice.

Problem Nell's mom makes chocolate milk with 30mL of chocolate syrup for every 2 ounces of milk. Nell's dad adds 65mL of chocolate syrup for every 5 ounces of milk. Whose chocolate milk is more chocolatey?

a- Nell's Mom
b-Nell's Dad
c- They're both equally chocolately

12 POINTSS

Answers

Nell's mom: 30 mL for 2 ounces = 15 mL for 1 ounce

Nell's dad: 65 mL for 5 ounces = 13 mL for 1 ounce

15 > 13
Therefore, Nell's mom's chocolate milk is more chocolately.

Answer:

(A) Nell's mom

Step-by-step explanation:

It is given that Nell's mom makes chocolate milk with 30mL of chocolate syrup for every 2 ounces of milk.

⇒For 1 ounce of milk, she will make chocolate milk=[tex]\frac{30}{2}=15mL[/tex]

Also, it is given that Nell's dad adds 65mL of chocolate syrup for every 5 ounces of milk.

⇒For 1 ounce of milk, he will make chocolate milk=[tex]\frac{65}{5}=13mL[/tex]

Since, Nell's mom made 15mL of chocolate milk and his dad made 13mL of chocolate milk, thus Nell's mom made chocolate milk more chocolatey.

Hence, option A is correct.

Julio is in Colorado exploring part of the Denver Zoo as shown he starts at the felines exhibit and travels 3 unit to the right and 5 units up at which exhibit is Julio located at the felines exhibit is located at (3,1) what are the coordinates of Julio's new location

Answers

Starting with his original coordinates (3, 1), going 3 units right gives us (3+3, 1) = (6, 1).  Going 5 units up then gives us (6, 1+5) = (6, 6) for his new location.
Final answer:

To find Julio's new location at the Denver Zoo, we add his horizontal and vertical movements to his starting coordinates. After moving 3 units to the right and 5 units up from the felines exhibit at (3,1), Julio's new location is at coordinates (6,6).

Explanation:

The student is asking about a basic coordinate geometry problem. Julio is at the felines exhibit at coordinates (3,1). To find Julio's new location after traveling 3 units to the right and 5 units up, we add the horizontal and vertical movements to his starting coordinates.

The movement to the right corresponds to an increase in the x-coordinate, while the movement up corresponds to an increase in the y-coordinate. Starting from the point (3,1), moving 3 units to the right means the x-coordinate changes from 3 to 3 + 3 = 6. Moving 5 units up means the y-coordinate changes from 1 to 1 + 5 = 6. Thus, Julio's new coordinates are (6,6).

Last week, Mr. Thomas rode his bike 49 miles. This week, Mr. Thomas rode his bike 14 miles less than he did last week. Part A. Mr. Thomas rode the same distance each of the 7 days this week. Write an equation to find the number of miles, m, he rode each day. Part B. How many miles did Mr. Thomas ride each day? Part C. Mr. Thomas says his goal is to ride a total of 125 miles by the end of next week. He estimates that he needs to ride about 40 miles next week to meet his goal. Is his estimate reasonable? Explain why or why not.

Answers

Part A
