The amount of their deposit will be $981.75

Sum refers to the addition of two or more numbers.

The amount of their deposit will be the sum of no cashback deposit and the checks.

This means that the amount of their deposit will be 25 twenties + 19 tens + 28 fives + 18 ones + 15 quarters + $25 + $20 + $85.

By Solving it, we will get

[tex](25\times 20)+(19\times 10)+(28\times 5)+(18\times 1)+(15\times \dfrac{1}{4})+25+20+85=500+190+140+18+3.75+25+20+85\\=981.75[/tex]

So, the amount of their deposit will be $981.75.

Answer: The actual model is 3.055 feet tall.

Step-by-step explanation:

Given: The statue of liberty is 305.5 feet tall from the foundation of it pedestal to the top of its torch .

The height of the model of the statue = [tex]\dfrac{1}{100}\times\text{ (Height of actual model)}[/tex]

[tex]=\dfrac{1}{100}\times305.5\\\\=3.055\text{ feet}[/tex]

Step-by-step explanation:

[tex]550(1 - .25) = 550(.75) = 412.50 \\ [/tex]

Answer:

Step-by-step explanation:

21≤2.50+5s subtract 2.50 from both sides

18.50≤5s  divide by 5

s≥3.7  he can buy up to 3 bags at $5 each

Alonso brings $21 to the market to buy eggs and avocados. He gets eggs that cost $2.50. Then he notices that the store only sells avocados in bags of 3 for $5. He wants to buy as many avocados as he can with his remaining money. What is the largest number of avocados that Alonso can afford?

9 avocados

$21.00 - $2.50 = $18.50

3 × $5.00 = $15.00

$18.50 - $15.00 = $3.50

$15 = 3 bags of avocados  =  3 bags × 3 avocados = 9 avocados

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

f(x) = x + 8

f(x) = 10

10 = x + 8

minus 8 from the both sides

10 - 8 = x

2 = x

x = 2

Answer:

h = 5.42

r = 5.42

Step-by-step explanation:

Find h with respect to r:

V = πr²h = 500

h = 500/πr²

Plug this into the surface area equation:

SA = πr² + 2πrh

= πr² + 2πr(500/πr²)

= πr² + 1000/r

Differentiate and set to 0, solve for r:

dSA/dr = 2πr - 1000/r² = 0

2πr = 1000/r²

r³ = 500/π

r = (500/π)^1/3

≈ 5.42 cm

find h:

h = 500/πr²

= 500/[π(5.42)²]

= 5.42cm

Answer:

F. [tex] \frac{3}{4} [/tex]

Step-by-step explanation:

Constant of proportionality, k, = [tex] \frac{y}{x} [/tex]

The ratio of each given of values on the table will give you the same value, which represents k.

Thus, using the pair, (2, 1.5), k can be calculated as follows:

[tex] k = \frac{y}{x} = \frac{1.5}{2} [/tex]

Multiply the numerator band denominator by 10 to eliminate the decimal point.

[tex] = \frac{1.5*10}{2*10} = \frac{15}{20} [/tex]

Simplify

[tex] k = \frac{3}{4} [/tex]

Answer:

y = 3x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

Here m = 3 and c = 8 , thus

y = 3x + 8 ← equation of line

Answer:

Step-by-step explanation:

Answer:

A. y = [tex]\frac{2}{5}[/tex]x + 1

Step-by-step explanation:

A linear function is a function that has an exponential value of zero or one and that, when graphed, is a straight line. The only equation that fits this description is answer choice A. We can also use the process of elimination to figure out which answer choice is correct.

A: A is the correct answer because it has an exponential value of one, meaning that it will be a straight line.

B: B is incorrect because the x has an exponential value of 2, which tells us that the equation is quadratic, not linear. If you were to graph this equation, it would look like a parabola, not a straight line.

C: C is incorrect for the same reason as answer choice B, the exponential value of this equation is more than one, meaning that the equation can't be linear.

D: D is incorrect because it contains a radical [tex]\sqrt{x}[/tex]. When [tex]\sqrt{x}[/tex] is graphed, it looks like half of a parabola, which isn't a straight line.

Answer:

[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex] is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex]

As the highest power of the x-variable is 3 with the leading coefficients of 1.

solving to get the zeros

[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex]

[tex]0=x^3-6x^2+3x+10[/tex]              ∵  [tex]f(x)=0[/tex]

as

[tex]Factor\:x^3-6x^2+3x+10\::\:\left(x+1\right)\left(x-2\right)\left(x-5\right)=0[/tex]

so

[tex]\left(x+1\right)\left(x-2\right)\left(x-5\right)=0[/tex]    

Using the zero factor principle

if  [tex]ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]

[tex]x+1=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:x-5=0[/tex]

[tex]x=-1,\:x=2,\:x=5[/tex]

Therefore, the zeros of the function are:

[tex]x=-1,\:x=2,\:x=5[/tex]

[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex] is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Therefore, the last option is true.
