Answer:
1.x=10 and x=−2.
2. the answer is x=7,-1
3.=3, =1
Step-by-step explanation:
1.Since it is a quadratic equation, then it has, at the most, two solutions because the square root of the variable has a positive and negative value. Thus, the solutions to the given equation are x=10 and x=−2.
2.Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula. the you would simplify the equation.and the last thing that is to separate the equation.

Answer:
It would be 9 units.
Step-by-step explanation:
So to find the distance between two points, first start at one of the points then see how much distance there is between it and 0.
So taking 7 to start with, you would need to walk 7 units to get to 0.
However, we still need to get the distance till -2. So, we need to walk another 2 steps back, so it would be 9 units of walking in total.

(Use 3.14 for 1.) 5 in.
30 in.
Find the surface area.
square inches
Do NOT round your answer.
Given:
Radius of the cylinder = 5 in
Height of the cylinder = 30 in.
To find:
The surface area of the cylinder.
Solution:
The surface area of the cylinder is:
[tex]SA=2\pi r^2+2\pi rh[/tex]
Where, r is the radius and h is the height of the cylinder.
Putting [tex]r=5,h=30,\pi=3.14[/tex] in the above formula, we get
[tex]SA=2(3.14)(5)^2+2(3.14)(5)(30)[/tex]
[tex]SA=2(3.14)(25)+942[/tex]
[tex]SA=157+942[/tex]
[tex]SA=1099 [/tex]
Therefore, the surface area of the cylinder is 1099 square inches.
Which of the following correctly displays 3 u>-2s>
Answer: (d)
Step-by-step explanation:
According to the triangle law of vector addition, the two vectors acting on a body are represented by the two sides of a triangle taken in order then the third side gives the resultant of the two vectors taken in the opposite order.
Here, option (d) aligns well with the triangle law of vector addition. The third side is in opposite order w.r.t the two vectors represented by the two sides of triangle i.e. [tex]3\vec{u}-2\vec{s}[/tex]

On a scale drawing, the height of a tree is 3.75 inches. If the scale of the drawing is 1 in. : 50 ft, how tall is the tree?
HINT: Write and solve a proportion. You will compare 1 in to 50 feet and then determine how many feet 3.75 inches would be. REMEMBER: When writing your proportion, be sure that whichever (inches or feet) is on top and bottom of one ratio, it is in the same position (top or bottom) on other ratio.
A
187.5 ft
B
13.3 in.
C
187.5 in.
D
13.3 ft
Answer:
187.5 ft
Step-by-step explanation:
50 ft x 3.75 = 187.5

Answer:
0.98
Step-by-step explanation:
Assuming the number of questions on all the tests is 10,
9+9+10+10+10 / 50
You get 50 by doing 5 quizzes x 10 questions per quiz.
48/50 = 0.98
What expression is equivalent to (6•p)+3
Answer:
I am pretty sure the answer would be 6p+3
Step-by-step explanation:
I got this by solving (6 multplied by p) +3
You have to multiply 6 by p which will give you 6p
Than, you just add the +3 to the equation
This together would give you
(6*p) +3 = 6p+3.

A rectangular block of wood measures 5 inches wide. Over time, the width of the block of wood will shrink by 5%. A builder lets the block of
wood shrink. He wants to use it to fill a gap that measures 3.5 inches wide.
How much does the builder need to cut off the wood block so that it will fit exactly in the gap? Enter the answer in the box.
The builder needs to cut
inches off the block of wood.
Answer: [tex]3.675\ in.[/tex]
Step-by-step explanation:
Given
Wood shrinks 5% over the period of time
The width of the gap is 3.5 inch
The length of the rectangular block is 5 inch
So, the builder cut the rectangular block 5% bigger to compensate for the shrinkage
Required length is
[tex]\Rightarrow 3.5+5\%\times 3.5\\\Rightarrow 3.5+0.05\times 3.5\\\Rightarrow 3.5[1+0.05]\\\Rightarrow 3.675\ in.[/tex]

Answers:
A) The equation is d = 2tB) Independent variable = time; dependent variable = amount of cookies=========================================================
Explanation:
The independent variable is always long the horizontal axis. Often this is x, but we are using t in this case.
The variable t represents the amount of time in minutes. For instance, t = 2 means 2 minutes have elapsed. At this time, 4 cookies have been eaten as shown by the point (2,4). As another example, the point (3,6) means that d = 6 cookies have been eaten at time t = 3 minutes.
The equation is d = 2t because the '2' represents the rate of change of "eating 2 cookies per minute". Whatever the time value (t) is, we double it to get the value of d, which is the number of cookies eaten.

What is the measure of the inscribed angle that shares endpoints with a central angle measuring 58 degrees?
Answer:
29 degrees
Step-by-step explanation:
See attached image of an inscribed angle together with a central angle.
An inscribed angle is half the measure of the central angle! Always! In my image, if the measure of angle CAB is 58 degrees, then that is also the measure of arc CB. The inscribed angle CDB is half the measure of the intercepted arc CB, so it's 29 degrees.

Answer:
The correct answer is 1/3.
Step-by-step explanation:
The reason why is because there is 3 animals. Then one beaver. So it would be 1/3.
Answer:
0.33
Step-by-step explanation:
Because they are all equal, each animal has to have the same percentage. Because there are 3 options it can land on, the denominator is 3. Because the beaver is 1 of the 3, the answer is 1/3. 1/3 is equal to 0.33 rounded so the answer is 0.33.

Step-by-step explanation:
Solve for X:
2.5x+12=32
Step-by-step explanation:
2.5x+12=32
We move all terms to the left:
2.5x+12-(32)=0
We add all the numbers together, and all the variables
2.5x-20=0
We move all terms containing x to the left, all other terms to the right
2.5x=20
x=20/2.5
x=8
The value of x for the expression is,
⇒ x = 8
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;
Expression is,
⇒ 2.5x + 12 = 32
Now, We can solve for x as;
⇒ 2.5x + 12 = 32
Subtract 12 both side,
⇒ 2.5x + 12 - 12 = 32 - 12
⇒ 2.5x = 20
Divide by 2.5 both side,
⇒ x = 20 / 2.5
⇒ x = 200 / 25
⇒ x = 8
Thus, The value of x for the expression is,
⇒ x = 8
