Eli has a collection of football and baseball cards. In all, he has 360 cards in his collection. Twice the number of baseball cards is 30 less than three times the number of football cards. How many more baseball cards than football cards does Eli have?

Answers

Answer 1

Answer:

150 football cards

210 baseball cards

Step-by-step explanation:

b + f = 360

2b = 3f - 30

Change second equation to be:  2b - 3f = -30

Multiply first equation by -2 to get:  -2b -2f = -720

Add to get: -5f = -750

f = 150

b = 360-150 = 210

less than equal to or greater than 3827

Answers

Answer:

it is less than, greater than, equal to, and less than

Step-by-step explanation:

if the numerator is greater than the denominator the fraction is greater than 1 and therefore you will have a number greater than 3827, if the numerator is less than the denominator the fraction is less than 1 and you will have a number less than 1, if the numerator and denominator are equal the fraction is equal to 1

Answer:

2.  3,827 > 8/3   3.  3,827 > 8/8     4.  3,827 > 3/5

Step-by-step explanation:

In problem 2. 8/3 as a decimal is 2.6 so that means 3,827 is greater. In problem 3. 8/8 as decimal is 1 so that means 3,827 is greater. In problem 4. 3/5 as a decimal is 0.6 so that means 3,827 is greater. i hope this helps have a good day :)

Surface area of a rectangular prism form : A=2(wl+hl+hw)

Substitute in values from the question: 558=2[(9)(11)+h(11)+h(9)]

Multiply where applicable: 558=2[(99)+11h+9h]

Combine like terms: 558=2[(99)+20h]

Divide both sides by 2: 279=(99)+20h

*note- This step can also be seen as multiplying the right side by 2 without messing with the left at all (558=(198)+40h) then you would solve in the same fashion as I will from here just with the alternative numbering*

Subtract to isolate the h: 180=20h

Divide both sides to isolate the h: 9=h

Now we see that the missing dimension h=9in

*note- I did not bold the equations with squares so please don't be confused by that*

5.

Surface area of a cylinder form: A=2πrh+2π[tex]r^{2}[/tex]

Substitute in values from the question: A=2π(3)(5)+2π[tex]3^{2}[/tex]

Multiply were applicable: A≈94.2+56.5

Add remaining values: A≈150.8

Now we see that the total surface area is 150.8[tex]m^{2}[/tex]

*note- whenever we solve for volume or SA of a figure we square the unit ([tex]m[/tex]➞[tex]m^{2}[/tex])*

6.

Surface area of a cylinder form: A=2πrh+2π[tex]r^{2}[/tex]

Substitute in values from the question: A=2π(6)(2)+2π[tex]6^{2}[/tex]

*note- we use 6 instead of the given value 12 because the equation calls for the radius and not the diameter*

Multiply were applicable: A≈75.2+226.2

Add remaining values: A≈301.6

Now we see that the total surface area is 301.6[tex]in^{2}[/tex]

*note- whenever we solve for volume or SA of a figure we square the unit ([tex]in[/tex]➞[tex]in^{2}[/tex])*

The sum of the numbers 13 + 13 + 13 is 39.

What is Addition?

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum.

Given expression is,

13 + 13 + 13

Here 13 is added to itself three times.

When 13 added to 13, we get 13 + 13 = 26

Again if we add the number 13 to 26, we get 13 + 26 = 39

13 + 13 + 13

= 26 + 13

= 39

This can also be written in the form of multiplication as 3 × 13, which is also equal to 39.

Hence the number 13 added to itself three times gives 39.

Mr. pope lost 10 pounds in one month. At the end of the month, he weighed 240 pounds. By what percentage did Mr. Pope decrease he weight?
a. (4%)
b. (7%)
c.(10)
d.(15%)

Answers

The answer for this question would be a which is 4% and hopefully you get it right

Mr. Pope decreased his weight by 4 percent.

What is percentage?

A percentage is a portion of a whole thing written as a number between 0 and 100 instead of fraction.

Given that, Mr. pope lost 10 pounds in one month. At the end of the month, he weighed 240 pounds.

we need to find the percentage of decrease of his weight,

So, basically we will use here the concept of percentage change,

Formula = final amount - initial amount / initial amount x 100

Since, he lost 10 pounds and has 240 pounds so, initially he weighted = 240 + 10 = 250 pounds

So, percentage decreased = -10 / 250 x 100 = -4% [minus is the sign for decrease]

Hence, Mr. Pope decreased his weight by 4 percent.

Write an equation of the line and interpret the slope.​

Answers

Answer:

y=-100x+700

Step-by-step explanation:

Slope=Rise/Run=Δy/Δx=(y₂-y1)/(x₂-x₁)=(200-600)/(5-1)=(-400)/(4)=-100

So your slope would be m=-100

To find b, the y-intercept, we plug in a given output of y for a given input of x and solve for b:

y=mx+b (Slope-intercept form)

y=-100x+b (Equation so far)

200=-100(5)+b [Plugging in (5,200)]

200=-500+b

700=b

So since the y-intercept is b=700, then the equation of the line is y=-100x+700

You have the letters in the word "SCIENTIST." What is the probability that you pick a vowel,do not replace it,and then pick "T"?

Answers

Answer:

1/12

Step-by-step explanation:

Total choices = 9, vowels = I, E, I = 3

Hence, P (vowel) = 3/9 = 1/3

Since you do not replace it, new total = 8 and number of Ts = 2

Hence, P (T) = 2/8 = 1/4

As these events are dependent and T is picked after vowel,

total probability = 1/3 x 1/4 = 1/12
