Answer:
3
Step-by-step explanation:
It is 3 because fi you multiply 5 by 3 you get 15, and if you multiply 10 by 3 you get 30. Subtract 30 by 6 and get 24. And finally, if you multiply 2 by 3 it gives you 9. 9+12= 21.
Which is a simplified form of the expression -3p – 4 + 4p + 8?
A. -p - 4
B. 2p - 4
C. p + 4
D. 7p + 4
Answer:
C
Step-by-step explanation:
-3p – 4 + 4p + 8
Simplify by combining like terms
-3p + 4p = p
-4 + 8 = 4
The expression in it's simplest form would be p + 4
Answer:
The answer is C.
Step-by-step explanation:
-3p - 4 + 4p + 8 can be grouped into:
-3p + 4p - 4 + 8.
If you add the p's together and the numbers together, your answer should be:
p + 4.

Carl can paint a room 3 hours faster than Jennifer can. If they work together, they can complete the job in 2 hours. Using complete sentences, explain each step in figuring out how to determine the time it would take Jennifer to complete this job on her ow
Answer:
If they would both work at the same speed they would each take 4 hours to complete the room. So in total they would work 8 hours. But because Carl can finish three hours before Jennifer 3 hours of the eight already got to Jennifer. Then we divide the resting 5 hours by the two and then we have:
Jennifer:
3+2,5=5,5
Carl:
2,5

Answer:
[tex]2\sqrt{6}[/tex] = x
Step-by-step explanation:
We can use the Tan ratio to figure this out;
[tex]Tan(60) = \frac{x}{\sqrt{8} }[/tex]
Tan(60) * [tex]\sqrt{8}[/tex] = x
[tex]2\sqrt{6}[/tex] = x

The dimensions of a rectangular prism are shown in the table.
Length: 10 in
Width: 12 in
Height: 16 in
What is the surface area of the rectangular prism?
A wooden board has a volume of 0.225 cubic m and a mass of 146.25 kilograms.
What is the density of the board?
Answer:
650 kg/m³
Step-by-step explanation:
The density is the ratio of mass to volume. The volume is the product of the dimensions of the prism.
density = (146.25 kg)/((1.5 m)(0.75 m)(0.2 m)) = 146.25/0.225 kg/m³
= 650 kg/m³
Hope this answer helps you :)

Find the vertex of y=-2(x-4)2 + 3 and identify it as a minimum or a maximum
Answer:
Step-by-step explanation:
Remark
The minus sign in front of the 2 means that the quadratic has a maximum.
The vertex is already written in vertex form.
y= - 2 (x - 4)^2 + 3
The vertex is (4,3). Notice that the sign on the 4 changes. What you are trying to do is find the maximum point. That occurs when the minus number is made to be 0, which occurs when x = 4. The maximum y value is 3 when that happens.
I have enclosed a graph to show you all the details. Notice the maximum is when I've said it was and the roots have also been calculated.

Answer:
17 =x
Step-by-step explanation:
The angles are vertical angles, so they are equal
51 = 3x
Divide each side by 3
51/3 = 3x/3
17 =x
Answer:
C) 17
Step-by-step explanation:
Since the angle needed to be 51˚ we need to figure out which number that multiplies by 3 will get to 51˚ so 17 is the answer
17 times 3 is 51˚
Ian bought a used car. The value, y , of the car x years after his purchase is modeled by the equation y = 6500(0.875)x . What was the value of the car when Ian bought it?
Answer:
6500
Step-by-step explanation:
y = 6500(0.875)^x
When bought x = 0
y = 6500(0.875)^0
A number raise to 0 equals 1
y = 6500 * 1
y = 6500
What is the surface area of the cylinder shown? Use 3.14 for pie. 4cm for the Radius, and 9cm for the height.
==============================================
Work Shown:
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*(4)^2 + 2*3.14*4*9
SA = 326.56
Notes:
The answer is approximate. Use more decimal digits of pi to get a more accurate answer (though it will never be exact unless you leave it in terms of pi).The portion 2pi*r^2 is the fact we have two circular bases with area of pi*r^2 each.The portion 2*pi*r*h is the lateral area, or the area around the curved side. If you unfold this portion, as you would maybe a label on a soup can, it has base of 2*pi*r and height h. The base 2pi*r is the circumference of the circle of radius r.Answer:

Help please I don't really understand what to do here, so if somebody could find the answer that'd be great!
Answer:
See below.
Step-by-step explanation:
4.2 is 4 and 2 tenths.
4 is 40 tenths.
That means that 4.2 is 40 tenths plus 2 tenths, or 42 tenths.
First line: 4.2 / 6 = 42 tenths / 6
In the second line, we divide 42 tenths by 6. Since 42 divided by 6 = 7, then 42 tenths divided by 6 equals 7 tenths.
Second line: 4.2 / 6 = 7 tenths
In the third line, we write 7 tenths as a number. 7 tenths is the same as 0.7.
Third line: 4.2 / 6 = 0.7
Which statement is not true about the absolute value of -6?
A. It descrlbes the distance between -6 and 0 on the number line.
B. It equals the absolute value of 6.
C. It describes the distance between 6 and -6 on the number line.
D. It can be expressed as |-6|.
Answer:
C
Step-by-step explanation:
All the other answers are the same worded differently except c.
The distance between 6 and -6 is 12 so that is not correct for the absolute value of -6

Answer:
27 m
Step-by-step explanation:
We know that ABC = 42 degrees
and side length BC = 24m
tan42 = 24m/a
a = 24/tan42
a = 26.65m
round to nearest whole number
= 27 m

The polygons are similar. The area of one polygon is given. Find the area of the other polygon.
3 cm
12 cm
A-96 cm?
Answer:
Hello! answer: area is 6 cm2
Step-by-step explanation:
Triangle area formula: base × height ÷ 2 or base × height × 1/2 so...
12 × 16 = 192 192 ÷ 2 = 96
12 ÷ 4 = 3
16 ÷ 4 = 4
3 × 4 = 12 12 ÷ 2 = 6 therefore the area is 6 hope that helps!
Answer:
6 cm²
Step-by-step explanation:
Given the sides of 2 similar figures in the ratio a : b , then
ratio of areas = a² : b²
Here the ratio of sides = 3 : 12 = 1 : 4
ratio of areas = 1² : 4² = 1 : 16
That is the area of the larger polygon is 16 times the smaller, so
area of smaller polygon = 96 ÷ 16 = 6 cm²

Step-by-step explanation:
[tex]\lim_{x \to 7} \frac{\sqrt{x+2}-3 }{x-7}[/tex]
[tex]\frac{\sqrt{x+2}-3 }{x-7}[/tex]
[tex]\frac{\frac{1}{2} (x+2)^{-\frac{1}{2} }}{1}[/tex] <-- Take derivative of numerator and denominator expressions
[tex]{\frac{1}{2} (x+2)^{-\frac{1}{2} }}[/tex] <-- Simplify
[tex]\frac{1}{2}(\frac{1}{\sqrt{x+2} })[/tex] <-- Rewrite
[tex]\frac{1}{2}(\frac{1}{\sqrt{7+2} })[/tex] <-- Use direct substitution and plug in the limit x=7
[tex]\frac{1}{2}(\frac{1}{\sqrt{9} })[/tex]
[tex]\frac{1}{2}(\frac{1}3 })[/tex]
[tex]\frac{1}{6}[/tex]
Therefore, [tex]\lim_{x \to 7} \frac{\sqrt{x+2}-3 }{x-7} = \frac{1}{6}[/tex]
