Answers

Answer:

[tex]{a}^{2} - {b}^{2}= {(80)}^{2} -{(45)}^{2} \\(a + b)(a - b) = (80 + 45)(80 - 45) \\ = 125 \times 35 = \boxed{ 4375}✓[/tex]

Could someone explain how to solve this

Answers

Answer:

y=\frac{4x}{5}-5

Step-by-step explanation:

linear equation

y=mx+b

We can see that when x=0 y= -5

THis means that b= -5 so we have

y=mx-5

We then know that when x=5 y= -1 so we have

-1=5m-5

Solve this and get m= 4/5

So we have

[tex]y=\frac{4x}{5}-5[/tex]

Answer:

f(x) = [tex]\frac{4}{5}[/tex]x - 5

Step-by-step explanation:

f(5) = -1 and f(0) = -5 mean that f has points at (5, -1) and (0, -5).

You can find the slope using the two points:

slope = [tex]\frac{-1 - (-5)}{5 - 0}[/tex] = [tex]\frac{4}{5}[/tex]

Then use point-slope form to make equation:

y - (-5) = [tex]\frac{4}{5}[/tex](x - 0)

y + 5 = [tex]\frac{4}{5}[/tex]x

y = [tex]\frac{4}{5}[/tex]x - 5

What is the missing value:

[tex]\frac{16}{1}[/tex] =[tex]\frac{x}{2 \frac{1}{2} }[/tex]

Answers

Answer:

[tex] x = 40 [/tex]

Step-by-step explanation:

[tex] \dfrac{16}{1} = \dfrac{x}{2 \frac{1}{2}} [/tex]

Convert the mixed numeral into a fraction.

[tex] \dfrac{16}{1} = \dfrac{x}{\frac{5}{2}} [/tex]

Multiply both sides by 5/2.

[tex] \dfrac{5}{2} \times \dfrac{16}{1} = x [/tex]

[tex] x = \dfrac{80}{2} [/tex]

[tex] x = 40 [/tex]

Mrs. Wright makes cookies for the school bake sale. She uses the equation y = 0.50x to determine the cost, y, for x cookies. Which best represents the constant rate at which cookies are sold at the bake sale? The Answer choices are......
A.50 cookies per dollar
B. 5 cookies per dollar
C.$0.50 per cookie
D.$2 per cookie

Answers

Answer:

Option C : $0.50 per cookie is the right answer.

Step-by-step explanation:

Given that:

Equation used by Mrs. Wright is

y = 0.50x

Here,

y = cost of cookies

x = number of cookies

Thus,

Cost = Price per cookie * Number of cookies

On comparing

Cost per cookie = $0.50

Hence,

Option C : $0.50 per cookie is the right answer.

Jackson and his sister ran a hose from a bucket into their swimming pool. The hose sprays 1/3 of a gallon from the bucket every second. The bucket started with 32 gallons of water. How long will it take to empty the bucket?

Answers

Answer:

96 seconds are taken to empty the bucket.

Step-by-step explanation:

According to this question, Jackson and his sister are spraying from the bucket from the bucket at constant rate. Dimensionally speaking, discharge time ([tex]t[/tex]), measured in seconds, is the ratio of volume of bucket ([tex]V[/tex]), measured in gallons, to the volume flow from hose ([tex]\dot V[/tex]), measured in gallons per second. That is:

[tex]t = \frac{V}{\dot V}[/tex] (1)

If we know that [tex]V = 32\,gal[/tex] and [tex]\dot V = \frac{1}{3}\,\frac{gal}{s}[/tex], then discharge time is:

[tex]t = \frac{32\,gal}{\frac{1}{3}\,\frac{gal}{s} }[/tex]

[tex]t = 96\,s[/tex]

96 seconds are taken to empty the bucket.

What is the inverse of the function f(x) = 4x + 8?
O h(x) = 1/4x - 2
O h(x) = 1/4x + 2
O h(x) = 1/2x - 2
O h(x) = 1/2x + 2

Answers

To find the inverse of a function, you swap the x and y values. So instead of y=4x+8, it becomes x=4y+8. Now you re-solve for y, and that’s your answer:

x=4y+8
x-8=4y
1/4x-2=y
So h(x)=1/4x-2, or the first option

so one point is (0,3)

when x=2,y=f(x)=2(2)+3=4+3=7

so point is (2,7)

In ΔKLM, l = 660 cm, ∠L=107° and ∠M=18°. Find the length of k, to the nearest 10th of a centimeter.

Answers

Answer:

565.3 cm

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.

Sine rule states that given a triangle with sides a, b, c and their corresponding angles opposite to the sides as A, B, C. Then:

[tex]\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}[/tex]

In triangle KLM:

∠K + ∠L + ∠M = 180° (sum of angles in a triangle)

∠K + 107 + 18 = 180

∠K + 125 = 180

∠K = 55°

We can find the length of k using sine rule:

[tex]\frac{l}{sinL}=\frac{k}{sinK} \\\\substituting:\\\\\frac{660}{sin(107)}=\frac{k}{sin(55)} \\\\k=\frac{660}{sin(107)}*sin(55)\\\\k=565.3\ cm\\[/tex]
