An accounting machine operator wanted to divide a 65 minute job between two identical machines so that one machine would take one and a half times as long as the other. How much time was taken by the machine doing the longer job?

Answer:

 ≥ 50 sets

Step-by-step explanation:

Mayerlin wants to know how many sets of 8 forks she needs to buy to increase her supply of forks from 223 to at least 623.

The number of additional forks will be the number of sets (s) times 8 forks each. Mayerlin wants at least 623.

  223 +8s ≥ 623 . . . . . . the inequality

Subtract 223:

  8s ≥ 400

  s ≥ 50 . . . . . . divide by 8

Mayerlin could by at least 50 sets of forks to have enough.

Answer:

13

Step-by-step explanation:

Hypotenuse is c

so c^2 = a^2 + b^2

c^2 = 5^2 + 12^2

c^2 = 25 + 144 = 169

c^2 = 13^2

c = 13

Pythagorean theorem:

Pythagorean theorem is the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2

The Pythagorean Theorem is tremendously useful. In many realistic scenarios it is possible to measure a and b with ease, but it is often difficult to measure c. For instance, c might pass through a lake or private property or might be up in the air! We'll do a few example puzzles in class together to show you how this works.

Nonetheless, the Pythagorean Theorem still presents a substantial limitation to utility. Specifically, it requires that the angle between a and b is 90 degrees. If the angle is not 90 degrees, the Pythagorean Theorem doesn't help.

This is where the Law of Cosines comes in. The Law of Cosines allows us to find c even when the angle between a and b is not 90 degrees. Check out this applet which illustrates the relationship between a2 and b2 and c2 that also takes into account the angle C (note the angle is capital C to distinguish it from lower case c, the side opposite angle C) between the legs a and b.

Adjust the blue dots in the triangle on the right right side of the screen to see the relationship. At the outset, when angle C is 90 degrees, a2+b2 is exactly equal to c2. However, when you move any of the three vertices of the triangle, note that the equality is not maintained. The problem is that angle C becomes not 90 degrees.

Now ,

a= 10

c= 13

b=?

a2 + b2 = c2

[tex]10^{2} +b^{2} = 13^{2} \\\\100+ b^{2} = 169\\\\b^{2} = 169-100\\\\b=\sqrt{69}[/tex]

Answer:

h(-4) = 72

Step-by-step explanation:

Given:

h(x) = 5x² +2x

Evaluate the function h(x) = 5x²+2x for x=-4 means to

find h(-4) by substituting x with -4:

h(-4) = 5·(-4)² +2·(-4)

If a, b, c, and d are four different numbers and the proportion. The given statement is true.

We take one example,

When you split them, they will all equal the same thing.

A = 5 ,B = 20 20 divided by 5 equals 4

C = 28 ,D = 7 28 divided by 7 equals 4

The ratio is used to compare two amounts of the same type. For two numbers, a and b, the ratio formula is written as a: b or a/b. The ratio and proportion concepts are based on fractions. Ratio and proportion are the fundamental building blocks for many other notions in mathematics. Ratio and proportion are useful in addressing many everyday difficulties, such as comparing heights, weights, distance, or time, or when combining ingredients in cookery, and so on.

Answer:

$6

Step-by-step explanation

$32 is the total(100%)

in order to find what she needs to tip, you have to divide by 5 because 100% / 5=20%

now, to find 20% of 32, you divide 32 by 5.

32 you can just round to 30, so that you can divide it by 5.

30/5=$6

you could've rounded the total up to 35, but 30 was closer, therefore $6 was the closest whole number tip rosita could've left.

Considering the circumference of a circle, it is found that Eric has walked 151.68 km.

The missing information is that the lake is a circle of radius 5 miles.

The circumference of a circle of radius r is given by:

C = 2πr.

Hence the circumference in miles of the circle is:

C = 2π x 5 = 10π miles.

This is the length of one lap, hence the length of 3 laps is:

3 x 10π = 30π miles.

In kilometers, the distance is:

30π x 1.60934 = 151.68 km.

Hence Eric has walked 151.68 km.

Answer:

y = -1/4x + 7/4

Step-by-step explanation:

m = (y2-y1)/(x2-x1)

m = (3 - 0)/(-5 - 7) = 3/(-12) = -1/4

using m = -1/4, y = 0 , x = 7

y = mx + b

0 = -1/4(7) + b

0 = -7/4 + b

b = 7/4

y = -1/4x + 7/4

The value of x in the equilateral triangle is 10

The equilateral triangle's three characteristics are: Equal on all three sides. The three angles are identical. Three symmetry lines may be seen in the figure. Additionally, each inside angle is identical (60 degrees).

A unique isosceles triangle with three equal sides is called an equilateral triangle. The formulas that we take into account most frequently for a triangle are: Dimensions of an equilateral triangle , the equilateral triangle's circumference, Equilateral triangle's height

An equiangular triangle's area can be calculated using the following formula:

If A=√3a2/4, then ABC's perimeter 3a

where a is the triangle's side length.

In equilateral triangle, the sum of the 3 angles are 180°.then the angle of each side is 60°

From the given data,

(7x-10)°=60°

7x=60+10

7x=70, x=10

Natalie will be paid $656.61 every week in addition to $10505.76 for the summer.

The combination of numerical variables and operations expressed by the addition, subtraction, multiplication, and division signs constitutes a mathematical expression.

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

Given that Natalie works as a playground supervisor for 8 weeks over the summer and makes $15.27 per hour. She works a 40-hour work week, although she usually works 3 hours of overtime.

For a week = ( 40 + 3 ) x 15.27 = $656.61

For a summer = 4 x 4 = 16 weeks

For a summer = 16 x $656.61 = $10505.76

Therefore, Natalie will be paid $656.61 for a week and for summer $10505.76.

Answer:

Step-by-step explanation:

You are asked to identify the real number properties that justify various changes in the way an expression is written.

In general, there are associative, commutative, identity, and inverse properties of addition and multiplication. You can use these properties to simplify and rewrite expressions, and to help perform arithmetic.

This is basically a vocabulary question, to see if you know the names associated with the behaviors these properties describe.

When an operation (such as addition or multiplication) has the commutative property, it means the order of its operands does not matter

  addition: a + b = b + a

  multiplication: a × b = b × a

When an operation has the associative property, it means that grouping of operands does not matter.

  addition: (a + b) + c = a + (b + c)

  multiplication: (ab)c = a(bc)

When an operation is performed using its identity element, the value of the other operand is not changed:

  addition: a + 0 = a

  multiplication: a × 1 = a

When an operation has an inverse, performing the operation with the inverse produces the identity element.

  addition: a + (-a) = 0

  multiplication: a × (1/a) = 1

Note: these last two properties are used to simplify and solve algebraic expressions. They let you "undo" operations done to variables or expressions.

You can match the given expressions to the example expressions shown above. The "multiplication property of zero" is also known as the "zero product rule": a product is zero if and only if a factor is zero.

  [tex]\begin{aligned}d\cdot4=4\cdot d\quad&\text{commutative property, multiplication}\\(2+a)+8=2+(a+8)\quad&\text{associative property, addition}\\m+(-m)=0\quad&\text{additive inverse property}\\0\cdot b=0\quad&\text{multiplication property of 0}\end{aligned}[/tex]

Based on the records of Dexter Technology, the net income using the cash-basis is $20,500 and the net income using accrual basis is $28,800.

Using the cash basis, the net income will be only for transactions that cash has either been received for or paid for:

= Cash from customers - Cash paid for salaries

= 45,000 - 24,500

= $20,500

The net income using accrual caters for the expenses and revenue that happened in a year regardless of when they are paid:

= Revenue - Salaries expense

= (45,000 - 1,200 + 7,000) - (24,500 - 6,000 + 3,500)
