Answer:
Larger number = 25
Smaller number = 14
Step 1. Establish variables and system of equations
Larger number = x
Smaller number = y
&
x + y = 39
y + 11 = x
Step 2. Isolate a variable in ONE equation
x + y = 39
y = 39 - x
Step 3. Substitute that into the OTHER equation to find x
y + 11 = x
(39 - x) + 11 = x
50 - x = x
50 = 2x
25 = x
Step 4. Substitute that into the OTHER equation to find y
x + y = 39
(25) + y = 39
y = 14

The surface area, the lateral area and the volume are, respectively:
S = 100 mi², L = 200 mi², V = 500 mi³S ≈ 201.062 cm², L ≈ 508.938 cm², V ≈ 1809.558 cm³S = 139.5 km², L = 180 km², V = 558 km³S = 6 km², L = 108 km², V = 54 km³How to determine the volume, the lateral area and the surface area of each solid
The volume is a measure of the space occupied by the solid, the lateral area is the measure of the area occupied by lateral faces of the solid and the surface area is the area occupied by the cross section of the solid. Please notice that the volume of each prism is equal to the product of the surface area and the height of the solid and the lateral area is the sum of the areas of the lateral faces.
In this exercise we must follow these steps to obtain the required results:
Calculate the surface area.Calculate the lateral area.Calculate the volume.Lastly, we proceed to make the corresponding calculations:
Surface area - Figure 1S = (10 mi)² = 100 mi²
Lateral area - Figure 1L = 4 · (10 mi) · (5 mi) = 200 mi²
Volume - Figure 1V = S · h = (100 mi²) · (5 mi) = 500 mi³
Surface area - Figure 2S = 0.25 π · (16 cm)² ≈ 201.062 cm²
Lateral area - Figure 2L = π · (18 cm) · (9 cm) ≈ 508.938 cm²
Volume - Figure 2V = S · h = (201.062 cm²) · (9 cm) ≈ 1809.558 cm³
Surface area - Figure 3S = 0.5 · (5) · (9 km) · (6.2 km) = 139.5 km²
Lateral area - Figure 3L = (5) · (4 km) · (9 km) = 180 km²
Volume - Figure 3V = S · h = (139.5 km²) · (4 km) = 558 km³
Surface area - Figure 4S = 0.5 · (3 km) · (4 km) = 6 km²
Lateral area - Figure 4L = (9 km) · (3 km) + (9 km) · (4 km) + (9 km) · (5 km) = 108 km²
Volume - Figure 4V = S · h = (6 km²) · (9 km) = 54 km³

Find the length of the third side. If necessary, round to the nearest tenth.
4
Answer:
x=2.6
Step-by-step explanation:
We can use the Pythagorean theorem to find the third side
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
3^2 + x^2 = 4^2 where x is the unknown side
9 + x^2 = 16
Subtract 9 from each side
x^2 = 16-9
x^2 = 7
Take the square root of each side
sqrt(x^2) = sqrt(7)
x =2.645751311
Rounding to the nearest tenth
x = 2.6
Answer:
2.65
Step-by-step explanation:
take the length of the third side as x
so,take Pythagoras theorem
4^2=3^2+x^2
16=9+x^2
x^2=16-9
x^2=7
x=√7
x=2.645
x=2.65
A supervisor finds the mean number of miles that the employees in a department live from work. he finds x overbar = 29 and s = 3.6. which mileage is within a z-score of 1.5? 21 miles 24 miles 36 miles 41 miles
A supervisor finds the mean number of miles that the employees in a department live from work is 24. Then the correct option is B.
What is a z-score?The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The z-score is given as
[tex]z = \dfrac{x-\mu }{s}\\[/tex]
x = 29
s = 3.6
z = 1.5
Then the mean will be
[tex]1.5 = \dfrac{29 - \mu }{3.6}\\\\\mu = 29 - 5.4\\\\\mu = 23.6 \approx 24[/tex]

6. Multiple: 2(8) = 16
7. Add: the result of step 5 + the result of step 6 = 136/3
+ 16 = 136/3

The Volume of air needed for a spherical balloon of radius 4 inch and circumference 8π is 85.3 cubic inch
Volume of SphereGiven Data
Circumference = 8πLet us find radius
circumference = 2πr
8π = 2πr
8 = 2r
r = 8/2
r = 4 inch
Let us find the volume of the sphere
Volume = 4/3πr^3
Volume = 4/3* π*4^3
Volume = 4/3*π64
Volume = 256π/3

so, the garden seems to be rectangular.
it has a length.
and width = length - 2
I assume the fence should go all around the rectangular garden.
that means it has to cover 2 lengths and 2 widths.
fence = 2×length + 2×(length - 2) =
= 2×length + 2×length - 4 = 4×length - 4 =
= 4×(length - 1)
length = 7.5 m
so, he will need

The length of a picture frame is 7 inches more than the width. For what values of x is the perimeter of the picture frame greater than 150 inches.
Answer:
x > 34
Step-by-step explanation:
Let x be the width of the picture frame
It then follows that the length = x + 7
Therefore, our inequality is:
[tex]2(x+7) +2x > 150\\2x+14+2x > 150\\4x > 136\\x > 34[/tex]
For all values of x greater than 34 the perimeter is greater than 150 inches.
Answer:
x is greater than 34 inches.
Step-by-step explanation:
Let x = width, then the length = x+7 inches.
Perimeter = 2(W + L) = 2(x + x + 7) = 4x + 14 , so:
4x + 14 > 150
4x > 150 - 14
4x > 136
x > 34.
