Answer:
0.027
Step-by-step explanation
If s = 0.3, and s is being cubed, that's the same as 0.3 cubed
Cubed just means to the third power.
So that mean o.3 cubed is the same as (0.3)(0.3)(0.3)
Therefore, the answer is 0.027

The linear inequality represented by the graph is y ≤ 1/2x + 2
How to determine the inequality?From the graph, we have the following highlights:
The graph crosses the y-axis at c = 2The graph is a less than or equal to graphNext, we calculate the slope (m) using:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
Using the points on the graph, we have:
[tex]m = \frac{4 -2}{4 -0}[/tex]
Evaluate
m = 1/2
The first highlight implies that the y-intercept is 2.
So, the linear inequality is:
y ≤ mx + c
This gives
y ≤ 1/2x + 2
Hence, the linear inequality represented by the graph is y ≤ 1/2x + 2

6 yd
18 yd
7 yd
15 yd
42 yd
The perimeter and the area of the shape are 63 square yards and 46 yards, respectively.
How do we calculate?The area of a triangle is equal to one half the product of its base and height. In the image, the base of the triangle is 18 yards and the height is 7 yards. Therefore, the area of the triangle is:
area = (1/2) * base * height
= (1/2) * 18 * 7
= 63 square yards
The perimeter of the shape is the sum of the lengths of all of its sides. In the image, the lengths of the sides are 6 yards, 18 yards, 7 yards, and 15 yards.
Therefore, the perimeter of the shape is:
perimeter = 6 + 18 + 7 + 15
= 46 yards

Answer:
(A) 33.9 (B) 22.6
Step-by-step explanation:
We first need to round to the nearest dollar for both prices. Lets examine both numbers.
$30.12 $19.93
We can round $30.12 to $30 since the number in the tenths place is 1 and we can round $19.93 to $20 since there is a nine in the tenths place.
Now we must find the tax for each number. We can do that by multiplying each number by 0.13 since that is 13% in decimal form. Lets do that now
[tex]30*0.13=3.9[/tex] [tex]20*0.13=2.6[/tex]
Now we can find the final price for each number by adding the tax to the rounded price.
[tex]30+3.9=33.9[/tex] [tex]20+2.6=22.6[/tex]
Hence, (A) 33.9, (B) 22.6
I really need the answer. Thanks to who'll help me.
Answer:
125 and 0.292
Step-by-step explanation:
Think about it as a system of equations:
1)
[tex]a+b=125 +1/3\\a=125.33-b\\\\2) ab=36+1/2\\[/tex]
at this point you can insert the equation you got from 1.
[tex](125.33-b)b=36.5\\125.33b-b^2=36.5\\b^2-125.33b+36.5=0[/tex]
with this form, you can use the quadratic equation to find your two possible answers.
following the quadratic equation we find that our answers are 125 and 0.292

The fraction that represents the addition model shown above will be 53/100.
How to solve the fraction?From the information given, a grid with 10 equal columns is shown with 5 shaded in. This will be expressed as 5/10.
Also, a second grid is shown, identical in size, containing 100 squares with 3 shaded in. This will be expressed as 3/100.
Therefore, the problem that represents the addition model shown above will be:
= 5/10 + 3/100
= 50/100 + 3/100
= 53/100
In this case, the answer given by Emma is incorrect as he added 5 to 3 and got 8/100.

Answer:
surface area of cuboid = 190 in²
surface area of triangular prism = 1240 yd²
surface area of cone = 791.28 ft²
Step-by-step explanation:
cuboid formula = 2( l x b + l x h + h x b )
solution:
S.A = 2(l x b + l x h + h x b)
S.A = 2(5 x 3 + 5 x 10 + 10 x 3)
S.A = 2(15 + 50 + 30)
S.A = 2( 95 )
S.A = 190 in²
triangular prism formula = 2(1/2 (b x h)) + 2(l x b) + l x b(this formula can only be used for this type of triangular prism)
solution:
S.A = 2(1/2 (b x h)) + 2(l x b) + l x b
S.A = 2(1/2 (15 x 16)) + 2(17 x 20) + 20 x 16
S.A = 240 + 680 + 320
S.A = 1240 yd²
cone formula = [tex]\pi[/tex]r(l + r) or [tex]\pi[/tex]rl + [tex]\pi[/tex]r²
solution:
S.A = [tex]\pi[/tex]r[l+r]
S.A = 3.14(9)[19 + 9]
S.A = 28.26 x 28
S.A = 791.28 ft²

Answer:
1.57 square feet
Step-by-step explanation:
Given :-
Radius = 2 feet
θ = 45°
Formula to be used :-
Area (sector) = πr² x θ / 360°
Inputting the values :-
= 3.14 x (2)² x 45/360
= 3.14 x 4 x 1/8
= 3.14 x 1/2
= 1.57 square feet
