Answer:
3+x sqrt 7 -13 is a radical equation.
The value of radical equation is,
⇒ 7√x = 14
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
All the equations are,
⇒ x +√5 = 12
⇒ x² = 16
⇒ 3 + x√7 = 13
⇒ 7√x = 14
Since, A radical equation is an equation with at least one variable put on a radical form.
In this question, there is only one kind of variable which is x.
Then, you need to find the equation where x is in the radical form.
Hence, The radical form can be expressed with square root symbol.
Therefore, The option with √x would be only,
⇒ 7√x = 14
Thus, The value of radical equation is,
⇒ 7√x = 14

Ava is going to the county fair. The cost of admission is $5.50 and it is $1.50 for each ride. If Ava has $19.00, Write and solve an equation to determine how many rides Ava can ride.
Answer:
5.50 + 1.50x = 19
x = 9
Ava can ride 9 rides.
Step-by-step explanation:
5.50 + 1.50x = 19
-5.50 -5.50
1.50x = 13.50 (divide both sides by 1.50)
x = 9
A store is instructed by corporate headquarters to put a markup of 25% on all items. An item costing $16 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Answer:
$20
Step-by-step explanation:
the manager's error could likely be putting the percentage mark up rather than the markup price added to the original price
25%×16
= $4
mark up price= (16+4)$
= $20

PLEASE HELP ASAP 10+ PTS!!
Answer:
(x,y) = (25,15)
Step-by-step explanation:
In a parallelogram, alternate angles are equal, so
[tex]\left \{ {{3x-8=4y+7} \atop {4x+13=5x-12}} \right.[/tex]
From the latter equation we obtain [tex]x= 13 + 12 = 25[/tex]. So substituting in the former equation gives
[tex]75-8 = 4y + 7\\4y = 60\\y = 15[/tex]
The radius of a sphere is increasing at a rate of 4 mm/s. How fast is the volume increasing (in mm^3/s) when the diameter is 60 mm
Answer:
The volume is increasing at a rate of 1508 cubic millimeters per second when the diameter is 60 mm.
Step-by-step explanation:
Volume of a sphere:
The volume of a sphere is given by the following equation:
[tex]V = \frac{4\pi r^3}{3}[/tex]
In which r is the radius.
Implicit derivatives:
This question is solving by implicit derivatives. We derivate V and r, implicitly as function of t. So
[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]
The radius of a sphere is increasing at a rate of 4 mm/s.
This means that [tex]\frac{dr}{dt} = 4[/tex]
How fast is the volume increasing (in mm^3/s) when the diameter is 60 mm?
This is [tex]\frac{dV}{dt}[/tex] when [tex]r = \frac{d}{2} = \frac{60}{2} = 30[/tex]. So
[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]
[tex]\frac{dV}{dt} = 4\pi*(30)^2*4[/tex]
[tex]\frac{dV}{dt} = 1508[/tex]
The volume is increasing at a rate of 1508 cubic millimeters per second when the diameter is 60 mm.

Suppose that a box of 86 circuits is sent to a manufacturing plant. Of the 86 circuits shipped, 5 are defective. The plant manager receiving the circuits randomly selects 2, without replacement, and tests them. If both circuits work, the manager will accept the shipment. Otherwise the shipment is rejected. What is the probability that the shipment is accepted
Answer:
the probability that the shipment is accepted is 0.8865
Step-by-step explanation:
Given the data in the question;
N = 86, n/d = 5 and n = 2
now, without replacement
the probability that the shipment is accepted will be;
probability that the shipment is accepted = probability that non is defectives
so p( non is defective ) = ( (86-5)/86) × ((86-5-1)/(86-1))
p( non is defective ) = ( 81 / 86) × (80/85)
p( non is defective ) = 0.8865
Therefore, the probability that the shipment is accepted is 0.8865

Answer:
A= [tex]4x+8[/tex]
B= [tex]8x+6x \\or\\ 16x[/tex]
C= [tex]8x+12[/tex]
D= [tex]6x+6y+6z[/tex]
Step-by-step explanation:
Distributing, or the means to divide something/create a share or part of something is when we multiply the sum of two or more addends by a number to achieve the same result as multiplying each addend individually by the number then adding the products together.
With this said, part A would look like this:
[tex]4(x+2)\\4(x) + 4(2) = ?\\4x + 8[/tex]
Now, the problem doesn't specifically state to solve the problem, but if you wanted too it would look like this:
[tex]4x + 8=0\\-8 \\4x=-8\\divide 4\\4=GCF\\x=-2[/tex]
Since we are just looking for the equation, the following problems would appear as so:
B:
[tex](6+8)*x\\x(8) + x(6)\\8x+6x\\14x[/tex]
C:
[tex]4(2x+3)\\4(2x)+4(3)\\8x+12[/tex]
D:
[tex]6(x+y+z)\\6(x) +6(y)+6(z)\\6x+6y+6z[/tex]
Another way to view the distributive property is that your distributing the number outside the parenthesis to all the number inside as such.

The solution of the expression is,
⇒ 43
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ Add 3 to the product 10 and 4
Now, We can simplify as;
⇒ 3 + (10 × 4)
⇒ 3 + 40
⇒ 43
Thus, The solution of the expression is,

When you multiply a given fraction by a factor greater than 1, the product will (always, sometimes, never) be less than the given fraction
9514 1404 393
Answer:
sometimes
Step-by-step explanation:
For positive numbers, multiplying by a factor greater than 1 increases their value:
(1/2) × 2 = 1 > 1/2
For negative numbers, multiplying by a factor greater than 1 decreases their value:
(-1//2) × 2 = -1 < -1/2
So, "sometimes" the product will be less than the given fraction.

Carlos paid an electrician x dollars per hour for a 4-hour job and $85 for parts. The total charge was $305. Which equation can be used to determine how much the electrician charged per hour?
Answer:
55
Step-by-step explanation:
The equation would be:
305=85+4x
220= 4x
x= 55
Answer: 4x + 85 = 305
To get your answer you just have to subtract 85 from 305 (I believe) and then divide what you got by four :)

Division of Labor:
There were 4 hobos that arrived in town looking for work. They met with a business owner who said he could pay them for 200 hours of work. However, there was a catch. They could divide up the work anyway they wanted, but each hobo had to work the same number of days as he/she worked hours in 1 day. For example, If a hobo worked 8 hours a day, he/she had to work for 8 days. The other catch is that the laziest hobo of all did the negotiations with the business owner and then went back to present the plan to his/her pals.
The question is how many hours a day did each hobo work?
