What is the value of the expression 9 x 4 - (2 x 1/2)
Answer:
35x
Step-by-step explanation:
Start with parentheses, 2 x 1/2 = 1
9 x 4 = 36
36 - 1 = 35

Social studies Geometry P.11 Similarity and altitudes in right triangles CEZ You have priz If SU = 28 and UV = 6, what is TU? T s V U Write your answer as a whole number or as a decimal rounded to the nearest hundredth. TU = Submit JUN E
Answer:
TU ≈ 12.96
Step-by-step explanation:
Using the Altitude on Hypotenuse theorem
(leg of outer triangle)² = (part of hypotenuse below it) × (whole hypotenuse)
TU² = UV × SU = 6 × 28 = 168 ( take square root of both sides )
TU = [tex]\sqrt{168}[/tex] ≈ 12.96 ( to the nearest hundredth )
What are the solutions of the equation (5x − 2)(x + 6) = 0?
A. 0.4, −6
B. no real solution
C. −0.4, 6
D. 2.5, −6
Answer:
A. 0.4 , -6
Step-by-step explanation:
equate each of them to 0
5x - 2 =0 , x + 6 = 0
5x = 2 , x = 0 - 6
x = 2/5 , x = -6
x = 0.4 , x = -6
What is the inequality for this verbal description?
The value of y is greater than or equal to the sum of five times the value of x
and negative three.
Answer:
y >= 5x - 3
Step-by-step explanation:
since the verbal description mentions "sum", we need to have at least two things to add together.
for this reason we cannot misinterpret the -3 as an element to be included in the "5 times" term, because otherwise we would not have a second thing to build a sum.

a cylindrical container has a radius of 14 cm and I 20m high .it's curved surface is completely covered with a label . what is the area of the label in cm2 .take pie to be 22/7)
Answer:
The area of the label is 176,000 cm²
Step-by-step explanation:
The given parameters are;
The radius of the cylindrical container, r = 14 cm
The height of the cylinder, h = 20 m
The area covered with the label = The curved surface of the cylinder, A
The curved surface area of a cylinder, A = 2 × π × r × h
π = 22/7
∴ The curved surface area of the cylinder = A = 2 × 22/7 × 14 × 2000 = 176,000
A = 176,000 cm²
∴ The area of the label = The curved surface area of the cylinder = 176,000 cm².

The function that represents the exponential graph is, [tex]y = 2^{x+2} + 3[/tex].
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
We know a function is called an exponential function when the exponent is the independent variable, For example, aˣ.
From the graph of the function, When x = 0, y = 7.
Observing the options we have,
[tex]y = 2^{x+2} + 3[/tex].
When x = 0.
[tex]y = 2^{0+2} + 3.[/tex]
[tex]y = 2^{2} + 3.[/tex]

The figure above shows a circle with center Cand
radius 6. What is the sum of the areas of the two
shaded regions?
160
С
Answer:
Sum of the areas of two shaded regions = 100 unit² (Approx.)
Step-by-step explanation:
Given:
Radius of circle = 6 units
Angle of one unshaded area = 160'
Find:
Sum of the areas of two shaded regions
Computation:
Angle of one shaded area = 180' - 160'
Angle of one unshaded area = 20'
Sum of the areas of two shaded regions = 2[θ/360][πr²]
Sum of the areas of two shaded regions = 2[160/360][(3.14)(6)²]
Sum of the areas of two shaded regions = 2[160/360][(3.14)(36)]
Sum of the areas of two shaded regions = 2[160/360][(3.14)(36)]
Sum of the areas of two shaded regions = [0.888][113.04]
Sum of the areas of two shaded regions = 100.46
Sum of the areas of two shaded regions = 100 unit² (Approx.)

A shooting star forms a right triangle with the Earth and the Sun, as shown below:
A right triangle is shown with the vertices labeled Earth, Sun, and Shooting Star. The angle formed by the Sun is labeled x deg
A scientist measures the angle x and the distance y between the Earth and the Sun. Using complete sentences, explain how the scientist can use only these two measurements to calculate the distance between the Sun and the shooting star. (10 points)
NO LINKS OR ABSURD ANSWERS
The distance between the Shooting Star and planet Earth is equal to the distance between the Sun and the Shooting Star multiplied by the sine of angle x.
How to calculate the distance?Fist of all, we would assign variables to the distance between these astronomical objects as follows:
Let EM be the distance between the Shooting Star and planet Earth.Let y be the distance between the Sun and the Shooting Star.Since the triangle is right-angled, we would use the sine trigonometry to determine the value of the distance between the Sun and the Shooting Star:
Sinθ = Opp/Hyp
Sinθ = EM/y
EM = y × Sinθ
Therefore, the distance between the Shooting Star and planet Earth is equal to the distance between the Sun and the Shooting Star multiplied by the sine of angle x.

Volume
Answer:
7. 1583.36 cm³
8. 13,627.18 m³
Step-by-step explanation:
Volume of space consumed by the paper = volume of outer cylinder - volume of center cylinder
✔️Volume of Outer Cylinder:
Volume = πr²h
r = ½(12) = 6 cm
h = 14 cm
Volume = π*6²*14
Volume = 1583.36 cm³
✔️Volume of center cylinder:
Volume = πr²h
r = ½(4) = 2 cm
h = 14 cm
Volume = π*2²*14
Volume = 175.93 cm³
✅Volume of space of the toilet paper = 1583.36 - 175.93 = 1583.36 cm³
8. Volume of the solid = volume of the cone + volume of the cylinder
✔️Volume of the cone = ⅓πr²h:
r = 13 m
h = 14 m
V = ⅓*π*13²*14
V = 2,477.67 m³
✔️Volume of the cylinder = πr²h
r = 13 m
h = 21 m
V = π*13²*21
V = 11,149.51 m³
✅Volume of the solid = 2,477.67 + 11,149.51 = 13,627.18 m³

Sara was choosing songs for her "Birthday Dance Party" shuffle tonight. She wanted to choose: 3 of her 8 Beyonce songs, 4 of her 12 Justin Timberlake songs, 2 of her 5 Drake songs, and finish it off with either Micheal Jackson or the Beatle's version of Happy Birthday. How many different ways can she make her Birthday song mix?
Answer:
554400
Step-by-step explanation:
To answer this question, we use combination as we are just interested in selection rather Than arrangement.
Beyonce songs ; 3 from 8 = 8C3
Justin ; 4 from 12 = 12C4
Drake ; 2 from 5 = 5C2
Version of happy birthday = 1 from 2 = 2C1
Recall :
nCr = n! ÷ (n-r)!r!
However, the answers can also be obtained using a calculator :
8C3 * 12C4 * 5C2 * 2C1 = 554400 different mix
