How do you find interval of increase or decrease??

Answer:

$4.60

Step-by-step explanation:

The customer will pay $0.80 per pound.  They are buying 5 and 3/4 pounds of nails, so they will pay..

$0.80(5) + $0.80(3/4) for the nails...now simplify...

$4.00 + $0.60 = $4.60

Answer:

You charge 4.6 cents the customer for nails.

Step-by-step explanation:

Given :The hardware store where you work charges .80 cents including tax for a pound of nails.

To Find : A customer purchases [tex]5\frac{3}{4}[/tex] pounds of nails. how much should you charge the customer for nails?

Solution:

Cost of 1 pound of nails including tax = 0.80 cents

Cost of  [tex]5\frac{3}{4}[/tex] pounds of nails:

=[tex]0.80 \times 5\frac{3}{4}[/tex]

=[tex]0.80 \times \frac{23}{4}[/tex]

=[tex]4.6[/tex]

Hence you charge 4.6 cents the customer for nails.

Answer:

Drinks = 6.75

Popcorn= 1

Step-by-step explanation:

Let the popcorn = P

Let the drink = D

2*P + 3*D = 22.25         multiply this equation by 6

12*P + 4D = 39.00

12P + 18D = 133.5          Subtract these two equations

- 14D = - 94.50               Divide by -14

-14D/-14 = -94.5/-14        Do the division

D = 6.75

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

12P  +  4D = 39            Substitute for D

12P + 4*6.75 = 39        Combine

12P + 27 = 39               Subtract 27 from both sides

12P + 27-27=39-27      Collect like terms

12P = 12                        Divide by 12

12P/12 = 12/12

P = 1                               Answer

Answer:

Step-by-step explanation:

First divide 1/4=0.25 and then multiply 0.25 bu 100% so the result is 25%

For the dumonitor remember that 4 x 25 is 100.

Our Multiple is 100.

So that means we need to multiply 1 and 4 by 25.

1×25 = 25 so our top number is 25.

4x25 is 100 which would be our bottom number.

We end up with 25/100.

That as a percent would be [tex]\fbox{25percent}[/tex] / 25%

.62, 7/9,10/9 the easyiest way to do this is by putting it in decimal form or just look 7/9 is more then .62 and 10/9 is a mixed number

Answer:

0.62, 7/9, 10/9

Step-by-step explanation:

First you want to convert the fractions to decimals.

10/9 = 1.110

7/9 = 0.778

0.62 = 0.62

then you order them from least to greatest.

0.62, 7/9, 10/9

The area of the circular stained-glass window is 50.24 square yards.

To find the area of the circular stained-glass window, we need to use the formula for the area of a circle: A = πr². Since we know the circumference of the window is 25.12 yards, we can use the formula C = 2πr to solve for the radius. Dividing both sides of the equation by 2π, we get r = C/(2π) = 25.12/(2 × 3.14) = 3.9996 yards. Now we can substitute this value of r into the formula for the area to find the window's area: A = 3.14 × (3.9996)² = 50.24 square yards.

Answer:

x = -5      

x=1

Step-by-step explanation:

f(x) = 1/3 (x+5) (x-1)

We want to find the zero's so set f(x) = 0

0 = 1/3 (x+5) (x-1)

Using the zero product property

x+5 = 0   x-1 =0

x+5-5 = 0-5      x-1+1 = 0+1

x = -5                  x=1

Answer:

x = -5, 1

Step-by-step explanation:

first you want to set both parenthesised equations to zero --

x + 5 = 0        x - 1 = 0

then just solve the one step equations--

x + 5 = 0      x - 1 = 0

  -5     -5        +1     +1

x = -5           x = 1

and you can leave the 1/3 alone (it actually has nothing to do with the zero product property)

AMSWER is A .180

formula perimeter of a rectangle

=2l + 2w

Perimeter of rectangle

21 + 2w = 16

as you know 21 is 2l,

one length

2l = 21

l =21/2

l = 10.5

Answer

10.5 inches

Answer:

[tex]l=8-w[/tex]

Step-by-step explanation:

We have been given that the perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is [tex]2l+2w=16[/tex], where [tex]l[/tex] represents the length of the rectangle and w represents the width of the rectangle.

Let us solve for [tex]l[/tex].

Factor out 2:

[tex]2(l+w)=16[/tex]

Divide both sides by 2:

[tex]\frac{2(l+w)}{2}=\frac{16}{2}[/tex]

[tex]l+w=8[/tex]

Subtract w from both sides:

[tex]l+w-w=8-w[/tex]

[tex]l=8-w[/tex]

Therefore, the expression [tex]8-w[/tex] represents length of rectangle.

if triangles are similar then corresponding internal angles are equal

=》 x = 180-(50+60) = 70degrees

The measure of angle x is the same as the measure of angle c which is,

x = 70°

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know triangles that are similar to each other have equal measures of corresponding angles.

Given, ΔABC ≈ ΔEDF,

Therefore, m∠B = m∠E = 50° and m∠D = m∠A = 60.

So, The measure of angle x is,

x = 180 - 50 - 60. (sum of interior angles equals 180°)

x = 180 - 110.

x = 70°.

Answer:

[tex]y + 1 = -\frac{5}{6}(x-6)[/tex]

or

[tex]y = -\frac{5}{6}x +4[/tex]

Step-by-step explanation:

Parallel lines are lines which have the same slope. To write the equation of the line parallel, find the slope of the equation 5x + 6y = 6 through conversion into slope intercept form.

5x + 6y = 6 becomes y = -5/6x + 1. The slope is -5/6.

Substitute\ m =-5/6 and the point (6,-1) into the slope intercept form.

[tex]y-y_1=m(x-x_1)\\y --1 = -\frac{5}{6}(x - 6)\\y + 1 = -\frac{5}{6}(x-6)[/tex]

Convert the equation to slope intercept form by applying the distributive property.

[tex]y + 1 = -\frac{5}{6}(x-6)\\y + 1 = -\frac{5}{6}x +5\\y = -\frac{5}{6}x +5-1\\y = -\frac{5}{6}x +4[/tex]

Answer:

The answer is (A) ⇒ G(x) = 7(-x)³

Step-by-step explanation:

* In transformation:

- Reflecting across the y-axis means change the sign of x-coordinate

- Stretch vertically means multiply f(x) by constant k, where k > 1

∵ F(x) = x³

- At first we reflect it across the y-axis

∴ We must change the sign of x to -x

∴ F(x) = (-x)³

- At second we stretch it vertically by constant 7

∴ We multiply F(x) by 7

∴ F(x) = 7(-x)³

∴ The answer is (A) ⇒ G(x) = 7(-x)³

In mathematics, inequality is a statement of an order relationship that can be greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.

Coordinate axes is the graph of the X and Y axis . A straight line can be plot in the coordinate axes plane by identifying its slope and the value of its y-intercept.

Given equation of straight line is y + 2 < 1/4x - 1

We solve the inequality in standard form of equation of straight line,

y < 1/4x - 3 , where slope is 1/4 and y-intercept is 3 when comparing with y = mx + c.

From the four graphs given in the Option, each and every graph has a slope of 1/4 and a y-intercept of -3 .

In Option (A) the portion indicating in the graph is the region which is less than -3 . Also from the equation, y < 1/4x - 3 we can see that the variation of the curve will always be less than -3 and it will also be a straight line and not a dotted line.

So the graph of Option(A) satisfies the straight line and inequality.

https://brainly.com/question/78672

Fractions less than 3/4 have a numerator to a denominator ratio that equals a number less than 0.75. Examples of such fractions are 1/2 and 2/3.

To determine which fraction is less than 3/4, it's important to remember that a fraction represents a division: the numerator (upper number) divided by the denominator (lower number). Fractions that are less than 3/4 have a ratio of the numerator to the denominator that results in a number less than 0.75, which is the decimal equivalent of 3/4.

For example, the fraction 1/2 is less than 3/4, because 1 divided by 2 equals 0.5, and 0.5 is less than 0.75. Similarly, the fraction 2/3 is less than 3/4, because 2 divided by 3 equals approximately 0.67, and 0.67 is again less than 0.75. Knowing the division values, even approximately, can help you quickly figure out if a fraction is less than or greater than another one.
