Consider the equation x = 5. Which statement is TRUE ?

Answer:

They spent $15.

Step-by-step explanation:

It's given that Jane bought x cookies, so 3x.

John spent $1 on each of the x cookies he got, and also an extra $10, so x+10.

3x=x+10

2x=10

x=5

So they got 5 cookies each.

5 cookies x $3= $15 (check with $5(1)+$10= $5+$10= $15 )

Answer:

After 11 weeks, Darnell′s savings account will have a total of $8,360.

Step-by-step explanation:

The data provided is as follows:

   n:    1        2       3        4

f (n): 260   360   460   560  

Consider the data for f (n).

The series f (n) follows an arithmetic sequence with a common difference of 100 and first term as 260.

The nth term of an arithmetic sequence is:

[tex]a_{n}=\frac{n}{2}[2a+(n-1)d][/tex]

Compute the value of f (11) as follows:

[tex]f(11)=\frac{11}{2}[(2\times260)+(11-1)\times 100][/tex]

        [tex]=5.5\times[520+1000]\\\\=5.5\times 1520\\\\=8360[/tex]

Thus, after 11 weeks, Darnell′s savings account will have a total of $8,360.

Answer:

The second one

Step-by-step explanation:

The true statement about the graph of x > -3 is open circle on -3 and all numbers to the right shaded.

A number system is defined as a system of writing to express numbers.

A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.

The given inequality is x>-3.

The value of x should be greater than -3.

The value -3 is not included.

In a number line the values are increased from left to right.

As x is greater than -3 which means the x values are increasing from left to right.

So the statement open circle on -3 and all numbers to the right shaded is true statement.

Hence,  the true statement about the graph of x > -3 is open circle on -3 and all numbers to the right shaded.

Answer:

11 months

Step-by-step explanation:

50m + 75 >= 600

just solve the inequality like how you would solve an equation, by inverse operations and simplifying

50m + 75 >= 600

        -75       -75

50m >= 525

/50        /50

m>= 10.5

just round up, because 0.5 of a month really isn't an answer

so 11 months

Answer:

im pretty sure the answer is c

it is twice as likely for the next spin to land on green as opposed to red.

Explanation:

you can check your answer by multiplying 7(red) twice and you do get 14(green) as your answer.

hope this helped:)

Answer:

C.

Step-by-step explanation:

A is wrong because 5 and 4 are not the same.

B is wrong because there is a higher chance for red to spin than yellow, 7 is more than 5.

C is right because green is double as likely to spin as red, 14 is double of 7

D is wrong because 12 is less than 14

Answer:

She should get $23.6 in change

Step-by-step explanation:

You add the two items she bought which makes up $89.94, then you subtract the discount of $13.50, which leaves you with 76.44 to pay. If you pay with a 100 dollar bill, you subtract 76.44 from 100 in order to find out how much change you recieve.

Answer:

Step-by-step explanation:

100-((39.95+49.99)-13.50)=

100-(89.94-13.50)=

100-76.44=

23.56

You have to add the amount she is paying for the total then subtract that by the discount. Then subtract how much she gave them by the cost to get the change!

Answer:

10 +c=3

C=3-10

C=-7

.....

Answer:

c = -7

10 more than a number c is 3

the variable is c, according to the sentence.

c

"10 more than a number c"

c + 10

"10 more than a number c is 3 "

c + 10 = 3

now that you have your equation, time to solve it.

it's important to know that if you do something to an equation, as long as you do it to both sides the equation is still true.

for example.

2 + 2 = 4

if you add 1 to both sides of the equation,

2 + 2 + 1 = 4 + 1

5 = 5

this is still true.

c + 10 = 3

subtract 10 from both sides of the equation.

c + 10 - 10 = 3 - 10

c = 3 - 10

c = -7

Answer:

Option (2)

Step-by-step explanation:

pH level of a substance is determined by the formula,

pH = - log[H+}

where [H+] is the hydrogen ion concentration

Let the [H+] ion concentration = a

a = -log[H+]

log[H+] = -a

[H+] = 1 × [tex]10^{-a}[/tex]

Here 'a' is between 7 and 14.

Which means an alkaline substance must have the concentration between [tex]1\times 10^{-7}[/tex] to  [tex]1\times 10^{-14}[/tex].

From the given options, [tex]5\times 10^{-12}[/tex] moles per liter lies in the given range.

Therefore, Option (2) will be the answer.

Answer:

Step-by-step explanation:

a). Perimeter of the kitchen = total length of all sides

                                              = 4 + 2 + 2 + 6 + 6 + 12 + 10  (Since side of one smallest square = 2 feet)

                                              = 42 ft

   Area of the kitchen = Area of the composite figure

                                     = 4² + 2² + (6 × 12)

                                     = 16 + 4 + 72

                                     = 92 square feet

b). Perimeter of bedroom = 2(length + width)

                                          = 2(12 + 8)

                                          = 40 feet

    Area of the bedroom = Length × Width

                                         = 12 × 8

                                         = 96 square feet

c). Perimeter of the bathroom = 2(9 + 4) = 26 feet

   Area of the bathroom = 9 × 4 = 36 square feet

d). Perimeter of the closet = 2(6 + 8) = 28 feet

   Area of the closet = 6 × 8 = 48 square feet

e). Area of the hallway = Total area of the floor plan - area of the (kitchen + bathroom + bedroom + closet)

  Area of the floor plan = 20 × 20 = 400 square feet

  Area of the hallway = 400 - (92 + 96 + 36 + 48)

                                    = 400 - 272

                                    = 128 square feet

Answer:

C. 8

Step-by-step explanation:

just did the quiz

This is equivalent to 2*sqrt(34)

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

Explanation:

First let's find BD

The three triangles are similar, allowing for the proportion to be set up

AD/BD = BD/DC

9/x = x/8

9*8 = x*x

x^2 = 72

x = sqrt(72)

BD = sqrt(72)

Now we can use the pythagorean theorem. Focus on triangle BDC.

The legs are BD = sqrt(72) and DC = 8. Let's find the hypotenuse

(BD)^2 + (DC)^2 = (BC)^2

(sqrt(72))^2 + (8)^2 = m^2

72 + 64 = m^2

136 = m^2

m^2 = 136

m = sqrt(136)

We can simplify this but your teacher has chosen not to. If you want to simplify, then,

m = sqrt(136)

m = sqrt(4*34)

m = sqrt(4)*sqrt(34)

m = 2*sqrt(34)

Answer:

(- [tex]\frac{15}{2}[/tex], 25 )

Step-by-step explanation:

Given the 2 equations

y = - 4x - 5 → (1)

y = - 2x + 10 → (2)

Substitute y = - 2x + 10 into (1)

- 2x + 10 = - 4x - 5 ( add 4x to both sides )

2x + 10 = - 5 ( subtract 10 from both sides )

2x = - 15 ( divide both sides by 2 )

x = - [tex]\frac{15}{2}[/tex]

Substitute this value into either of the 2 equations and evaluate for y

Substituting into (2)

y = - 2(- [tex]\frac{15}{2}[/tex] ) + 10 = 15 + 10 = 25

Solution is ( - [tex]\frac{15}{2}[/tex], 25 )

Answer:

D. Output = 6 - Input

Step-by-step explanation:

The output is the y-value, while the input is the x-value. The coordinates are represented as (x, y), and are graphed in the figure attached below.

Let's consider the function and see which rule best describes the function.

Considering the point (1, 5), the rule, output = 6 - input, applies.

Let's check it out:

Output is 5, input is 1. Substitute 1 as input into the rule, Output = 6 - input, and see if it would give you 5 as output:

Output = 6 - 1

Output = 5

If you try another coordinate pair of the function, the same rule will apply.

Therefore, the best answer is D. Output = 6 - Input
