Answer:

[tex]3\ \frac{15}{16}[/tex]

Step-by-step explanation:

The mixture  requires 3/8 cup of plant food for every gallon of water

Then it requires (10 1/2)×(3/8) cup of plant food for 10 1/2 gallons of water

Now we have to calculate (10 1/2)×(3/8)

[tex]10\ \frac{1}{2} \ =\ \frac{10\times 2}{2} +\frac{1}{2} \ =\frac{20+1}{2} =\frac{21}{2}[/tex]

[tex]\frac{21}{2} \times \frac{3}{8} =\frac{63}{16} =3\ \frac{15}{16}[/tex]

then he needs :

[tex]\frac{63}{16}\ \ \text (cup\ of\ plant\ food)[/tex]

Problem 9

Reason:

The height of the cylinder is 2.5 ft. It's misleading because the cylinder is tipped onto its side, so it appears that 4 ft is the height. The height of any cylinder is always perpendicular to the circular base. It might help to rotate the paper so that the circular base is horizontal.

==============================================================

Problem 10

Reason:

The diameter of the base is 4 feet, which divides in half to 2 feet and it's the radius of the circle.

Area = pi*(radius)^2 = pi(2)^2 = 4pi

So the area expression should be either pi(2^2) or pi(4) or 4pi

==============================================================

Problem 11

Reason:

V = pi*r^2*h

V = 3.14*2^2*2.5

V = 31.4 cubic feet

This volume is approximate since pi = 3.14 is approximate.

What is the question You are just stateing facts?

Step-by-step explanation:

The rule for the height of the tree during the nth month will be an = 83 + 1.5(n – 1). The correct option is A.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that in the third month of the study, a sugar maple tree is 86 inches tall. In the seventh month, the tree is 92 inches tall.

For option A satisfy the equation for n = 3 and n = 7,

an = 83 + 1.5(n – 1)

a₃ = 83 + 1.5(3 – 1)

a₃ = 83 + 3

a₃ =86

a₇ = 83 + 1.5(7– 1)

a₃ = 83 + ( 1.5 x 6 )

a₃ = 83 + 9

a₃ = 92

Therefore, the rule for the height of the tree during the nth month will be an = 83 + 1.5(n – 1). The correct option is A.

Answer:

The Perimeter of the trapezoid = 42.6 inches

Step-by-step explanation:

______

Formula:

let a , b , c , d be consecutively the lengths of the sides of the trapezoid

then

The Perimeter of the trapezoid  = a + b + c + d

___________________________________

Suppose a = 11 , b = 1.5 , c = 11 , d = 19.1

therefore,

The Perimeter of the trapezoid  = a + b + c + d

                                                     = 11 + 1.5 + 11 + 19.1

                                                     = 42.6

Given :   Eitan rolls a fair six-sided die and a fair four-sided die simultaneously. A be the event that the sum of the dice is 8 and B be the event that Eitan rolls doubles

To find : probability of event A  , event B  , Event A or B  , Event A & B

Solution:

Six  Sides  Dice has { 1 , 2 , 3 , 4 , 5 ,6  }

4 Sides Dice has  = {  1 , 2 , 3 ,  4 }

Total possible outcome = 6 * 4  = 24

n(S) = 24

A  = Sum of Dice  = 8

(4 , 4)  , ( 5 , 3) , ( 6 , 2)

n(A) = 3

B  =   Double  ( means same number on each Dice )

B = ( 1 , 1) , (  2, 2) , ( 3 , 3) , ( 4, 4)

n(B) = 4

A U B  = ( 1 , 1) , (  2, 2) , ( 3 , 3) , ( 4, 4) ( 5 , 3) , ( 6 , 2)

n (A U B )   =  { 6 }

A ∩ B = { 4 , 4}

n(A ∩ B)  = 1

Probability of Event A  =  3/24  = 1/8

probability of Event B = 4/24   = 1/6

Probability of Event A or B  = 6/24  = 1/4

Probability of Event  A and B = 1/24

out of the total donuts (90), Ryan ate 12 cream filled donuts. 45 is half of that, therefore he should eat half the cream filled donuts

Answer:

B (x= 14/3 , y= -5/3)

Step-by-step explanation:

A (x= 6, y= 1) and C (x= 2, y = -7)

On x-axis between A and C are 6 -2 = 4 units

On y-axis between A and C are 1 + 7 = 8 units

AB = (1/3) BC

Divide the distance between AC in 3 pieces

On x-axis will have 4/3 units on each piece

On y-axis will have 8/3 units on each piece

Now move away from A the 1/3 distance

A (x= 6, y= 1)

B (x= 6 -(4/3) , y= 1 -(8/3))

B (x= (18- 4)/3) , y= (3-8)/3))

B (x= 14/3 , y= -5/3)

The probability that a student is chosen randomly from the class plays both basketball and baseball is 4/21

Probability is the likelihood or chance that an event will occur.

Get the number of students that plays both basketball and baseball

n(U) = n(B)only + n(Ba)only + n(BnBa) + n(BuBa)'

21 = 6-x + 14-x + x + 5

21 = 25 -x

x = 25 - 21

x = 4

Hence 4 students play both basketball and baseball

Pr(basketball and baseball) = 4/21

Hence the probability that a student chosen randomly from the class plays both basketball and baseball is 4/21

Step-by-step explanation:

just solve them out

The expressions to the correct function combination is (f. g)(x).

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

f(x) = 12 - 61 – 27

g(t) = 1 - 9

Now,

To match the expressions to the correct function combinations, you can substitute the values of f(x) and g(t) into the expressions and simplify. For example:

( + 5)() = (f(x) + 5)(g(t))

( + 5)() = ((12 - 6x - 27) + 5)(1 - 9t)

( + 5)() = (17 - 6x)(1 - 9t)

( + 5)() = 17 - 153t - 6x + 54xt

Therefore, by the given equation the answer will be (f. g)(x).

Answer:

Starting with AT LEAST 2 A's means starting with 3 A's, or starting with 2 A's with some different letter third.

P(AAA...) = (3/9)(2/8)(1/7) = 1/84

Step-by-step explanation:

First note that any solution must belong to all of the intervals

x + 2 > 0   ⇒   x > -2

x > 0

2x - 1 > 0   ⇒   x > 1/2

3x - 12 > 0   ⇒   x > 4

so x must be larger than 4.

Recall that log(a) - log(b) = log(a/b). So we can rewrite

log(x + 2) - log(x) = log(2x - 1) - log(3x - 12)

log((x + 2)/x) = log((2x - 1)/(3x - 12))

Take the antilogarithm/exponential of both sides (note that the base of the logarithm doesn't matter here):

exp[log((x + 2)/x)] = exp[log((2x - 1)/(3x - 12))]

(x + 2)/x = (2x - 1)/(3x - 12)

Eliminate the fractions:

x (3x - 12) • (x + 2)/x = x (3x - 12) • (2x - 1)/(3x - 12)

(3x - 12) (x + 2) = x (2x - 1)

Expand both sides, collect terms and factorize to solve for x :

3x² - 6x - 24 = 2x² - x

x² - 5x - 24 = 0

(x - 8) (x + 3) = 0

x - 8 = 0   or   x + 3 = 0

x = 8   or   x = -3
