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 :)

Your cousin Pablo gets his haircut, and it costs $12.00. What will he spend in total on his haircut if he includes a 12% tip?
Answer:
The tip would be $1.44, so the total would be $13.44
Step-by-step explanation:
To find the tip you take the bill ($12), and multiply it by the percent of tip given (12%), but it has to be in decimal form. 12% in decimal form is .12. 12 times .12 is 1.44. Add $12 to that to get $13.44.
Answer:
Step-by-step explanation:
You could do this a couple of ways. The first and easiest is to change 12% to a decimal. 12% = 12/100 = 0.12
Add this onto 1.
1 + 0.12 = 1.12
Multiply this number by
12*1.12 = 12(1 +0.12) Remove the brackets
12*1 + 1.44
Haircut + tip = 13.44
Of course, it would be much shorter to do it 12*1.12 = 13.44

If f (x) = -2x2 + 6, find f (-3).
Answer:
Step-by-step explanation:
Answer:
f(- 3) = - 12
Step-by-step explanation:
To find f(- 3) substitute x = - 3 into f(x) , that is
f(- 3) = -2(- 3)² + 6 = -2(9) + 6 = - 18 + 6 = - 12
Multiply or divide
(K²) (k)
Algebra
For example, (x)(x)=x^2
Add the exponents of the variable to get the correct answer.
(k^3)(k^5)=k^8
Answer and Step-by-step explanation:
When two values have the same base, have exponents, and are being multiplied to each other, then we add together the exponents.
So, we are given k to the power of 3, which is multiplied by k to the power of 5. The powers (exponents) are added together to make 8, and the bases combine to be only one of the bases, being k.
So, we are left with the answer being [tex]k^8[/tex].
I hope this helps!

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.
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

help finding the volume
Answer:
1651.06 m³
Step-by-step explanation:
the volume of the whole block is base area times height :
Vb = 10 × 12 × 18
but we have to deduct the volume of the removed central cylinder.
the volume of the cylinder is again base area times height :
Vc = pi×r² × 18 = pi×3² × 18 = pi×9×18
so, the volume of the object is
V = Vb - Vc = 2160 - 508.94 = 1651.06 m³
Quandrilateral ABCD is inscribed in a circle. What is the measure of angle A? A=(2x-40)B 116 C D=x what is the measure of angle A
Answer:
angle A = 88°
Step-by-step explanation:
Given: inscribed quadrilateral ABCD
(recall that inscribed quadrilaterals have opposite angles supplementary.
A=2x-40
B=116
D=x
From inscribed quadrilateral,
B+D=180 => 116+x = 180 => x=64
A=(2x-40) = 2*64-40 = 88°
(C = 180-88 = 92°)
Help urgent please be certain
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˚

Javed is building a birdhouse in the shape of a triangular pyramid. He drew the net for his birdhouse and labeled the dimensions. The base is an isosceles triangle with two side lengths of 20 cm. How much wood will Javed need for the birdhouse?
Answer:
See attachment
Step-by-step explanation:
Required
How much wood needed (i.e. the surface area)
The question is incomplete, as the net of the triangular prism is not given. So, I will answer with the attached net.
To calculate the surface area, we simply calculate the area of each face of the net.
The area of the net is as follows:
Area= 2 * Area of Triangle + 2 * Area of 2 Congruent Rectangles + Area of the third rectangle
So, we have:
[tex]Area = 2 * \frac{1}{2} * 6 * 5 + 2 * 8 * 7 + 8 * 6[/tex]
[tex]Area = 30 + 112 + 48[/tex]
[tex]Area = 190cm^2[/tex]

What is the answer? i cant find it helpp
Answer:
The y intercept is 4
Step-by-step explanation:
The slope is
m= (y2-y1)/(x2-x1)
= (64-44)/(24-16)
= 20/8
For each increase of 8 we go up 20
So for each decrease of 8 we go down 20
(16,44)
(16-8, 44-20)
(8,24)
(8-8,24-20)
(0,4)
The y intercept is 4
