Answer:
The expression to find Carey's hourly rate is: [tex]c = 2*a - 2[/tex]. Carey's hourly rate is $10.
Step-by-step explanation:
Anderson receives 1 more than half of carey's hourly rate. If we call Anderson's rate by "a" and Carey's by "c", we can express this phrase in the following equation:
[tex]a = \frac{c}{2} + 1[/tex]
We want to find the Carey's rate, therefore we need to isolate the "c" variable.
[tex]\frac{c}{2} + 1 = a\\\frac{c}{2} = a - 1\\c = 2*a - 2[/tex]
Since Anderson earns $6, then we can find Carey's rate:
[tex]c = 2*6 - 2 = 12 - 2 = 10[/tex]
Answer:
A)
6 = c/2 + 1
A force of 76 N is applied to an area of 490 cm2. Calculate the pressure in N/m2. Give your answer to the nearest integer.
Answer:
Given
Hope it helps
Step-by-step explanation:
Pressure is the force per unit perpendicular area over which the force is applied
p=F/A
Where f is force and a is area
So P
= F/A
= 76N / 0.049m2
= (76/0.049) Nm2
= 76000/49
= 1551.02
Or 1551 N/m2

In a village the number of houses and the number of flats are in the ration9:5 the number of flats and the number pf bungalows are in the ratio 10:3 there are 30 bungalows in the village. How many houses are there in the village?
Answer: 180 houses
Step-by-step explanation:
From the question, we are informed that in a village the number of houses and the number of flats are in the ratio 9:5 while the number of flats and the number of bungalows are in the ratio 10:3 and that there are 30 bungalows in the village.
Since the ratio of the number of flats and the number of bungalows are in the ratio 10:3 and there are 30 bungalows in the village, the number of flats will be:
= 10/3 × 30
= 10 × 10
= 100 flats
Since we are told that the ratio of the number of houses to the number of flats are in the ratio 9:5 and we've gotten the number of flats as 100, then the number of houses will be:
= 9/5 × 100
= 9 × 20
= 180 houses

John, Peter and Mary shared a sum of
money in the ratio 2:4:9. John and Peter
together received $360. How much money
in all was shared?
(A) $480
(B) $540
(C) $600
(D) $900
Answer:
D
Step-by-step explanation:
Here, we want to know the total amount of money shared
Total ratio is 2 + 4 + 9 = 15
Now, John and Peter with ratios 2 and 4 equals $360
If we combine their ratios, what we have would be
6:9
Let the amount shared be x
Now, mathematically
6/15 * x = 360
6x = 15 * 360
x = (15 * 360)/6
x = $900

Part A: Create a fourth-degree polynomial with three terms in standard form. How do you know it is in standard form?
Part B: Explain the closure property as it relates to addition of polynomials. Give an example.
Answer:
Part A: x⁴ + x³ + x²
Part B: (4·x + 2) + (-5·x + 6) = -x + 8
Step-by-step explanation:
Part A:
We note that standard form means that the terms of the polynomial are arranged in order starting from the the largest exponential of the polynomial to the smallest exponent
Therefore, we have
x⁴ + x³ + x² is a fourth-degree polynomial with three terms in standard form
It is known that the above polynomial is in standard form based on its ordered arrangement from the largest exponential to the smallest exponential
Part B:
Polynomial are closed under addition, that is when two polynomials are added only the coefficients change as the exponents and variables remain unchanged as follows;
(4·x + 2) + (-5·x + 6)
= 4·x + 2 - 5·x + 6
= 4·x - 5·x + 2 + 6
= -x + 8 which is a polynomial with the same variable and exponent.

What is the slope of the line through the points (0,0) and (2,6)
Answer:
3
Step-by-step explanation:
The slope of a line can be found by dividing the amount that the line "rises" over a certain amount of "run". In this case, the line rises 6 units while moving 2 units to the right. 6/2=3, meaning that the slope of this line is 3. Hope this helps!
what is the key vocabulary of cubic functions
Answer:
Hope it helps!
Step-by-step explanation:
The general form of a cubic function is y = ax3 + bx + cx + d where a , b, c and d are real numbers and a is not zero. We can graph cubic functions by plotting points.
A cubic function is any function of the form y = ax^3 + bx^2 + cx + d, where a, b, c, and d are constants, and a is not equal to zero, or a polynomial functions with the highest exponent equal to 3. These types of functions are extremely prevalent in applications involving volume.

Find the area of a triangle, two sides of which are 10 cm and 16 cm and the perimeter is 38 cm.
Answer:
Step-by-step explanation:
third side=38-(10+16)=38-26=12
sides are 10 cm, 12 cm , 16 cm.
2s=10+12+16=38
s=38/2=19
area=√(s(s-a)(s-b)(s-c))
=√[19(19-10)(19-12)(19-16)]
=√[19×9×7×3]
=3√391 cm²
≈59.32 cm²

Gavin was thinking of a number. Gavin halves the number and gets an answer of 34.3. Form an equation with x as information.
Gavin's number is 68.6
Equation: 1/2(x) = 34.3
Use inverse operations on both sides.
1/2(x) = 1x or x = 34.3(2)
34.3(2) = 68.6
Thus, x equals 68.6
Gavin's number is 68.6.
What is multiplication?
In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life
here, we have,
Gavin halves the number and gets an answer of 34.3.
now, we get,
Equation: 1/2(x) = 34.3
Use inverse operations on both sides.
1/2(x) = 1x
or x = 34.3(2)
i.e. 34.3(2) = 68.6
Thus, x equals 68.6.

a carpenter can make 30 chairs, 25 tables and 15 beds in a month. what proportion of the carpenter's output is bed.
Answer:
3/14
Step-by-step explanation:
Express the beds as a fraction of the total output.
Beds = 15
Total output = 30 + 25 + 15 = 70
Proportion that is beds = 15/70
15/70 = 3/14
ANSWER SOON PLEASE! I WILL MARK BRANLIEST! The equation 7 x minus 10 y = 30 is written in standard form. What is the first step when writing an equivalent equation which solves for y? Add 7x to both sides of the equation. Subtract 7x from both sides of the equation. Add 30 to both sides of the equation. Subtract 30 from both sides of the equation.
Answer:
Subtract -7x from both sides
Step-by-step explanation:
You want to isolate the y term on one side of the equation
Answer:
The answer is option 2.
Step-by-step explanation:
The first step to solve for y, you have to subtract 7x on both sides in order to make y as a subject :
[tex]7x - 10y = 30[/tex]
[tex]7x - 10y - 7x = 30 - 7x[/tex]
[tex] - 10y = 10 - 7x[/tex]
PLEASE HELP FOR A BRAINLIEST!!!! Create your own example and explain how to solve Quadratic Equation using Quadratic Formula. What part in the Quadratic Formula is the discriminant and how do you know the number of solutions based on the value of the discriminant? Pls pls help I need YALLS brains
Step-by-step explanation:
1. Create your own example and explain how to solve Quadratic Equation using Quadratic Formula.
The quadratic formula is used to solve quadratic equations. It is shown as [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
A quadratic equation is generally shown in the form of [tex]ax^{2} +bx + c = 0[/tex]
For example, if you saw the equation [tex]7x^{2} + 3x + 20 = 0[/tex]
7 would be [tex]a[/tex], 3 would be [tex]b[/tex], and 20 would be [tex]c[/tex].
To solve the equation above, you would fill in the quadratic formula as such, [tex]x=\dfrac{-3\pm\sqrt{(3)^2-4(7)(20)}}{2(7)}[/tex]
Then you could solve for x.
2. What part in the Quadratic Formula is the discriminant?
The discriminant is the equation under the square root on the quadratic formula, [tex]b^{2} - 4ac[/tex]
It is tells us whether there are two solutions, one solutions, or no solutions.
3. How do you know the number of solutions based on the value of the discriminant?
To know the number of solutions based off of the value of the discriminant, you need to plug in your values. Using the example quadratic equation, [tex]7x^{2} + 3x + 20 = 0[/tex]
We will plug the values into the discriminant.
[tex]3^{2} - 4(7)(20) = -551[/tex]
Now, if the discriminant is positive it has two real solutions. If the discriminant is zero the equation has no real-number solutions. And finally, if the discriminant is negative, the equation has one real solution. Because our discriminant is -551, the example equation has one real solution.
