Answer:

Step-by-step explanation:

The first three cuboid prisms all use the same area formula:

  A = 2(LW +H(L+W))

__

1. A = 2(3·3 +7(3+3)) = 2(9 +42) = 102 . . . cm²

2. A = 2(2·8 +10(2 +8)) = 2(16 +100) = 232 . . . in²

3. A = 2(4.9·3 +0.7(4.9 +3)) = 2(14.7 +5.53) = 40.46 . . . ft²

__

4. The area of this prism is the total of the area of the two triangular bases  and the areas of the rectangular faces. For triangle legs a, b and hypotenuse c, and prism depth d, the area formula can be written as ...

  A = ab +d(a+b+c)

  A = (8 mm)(15 mm) +(9 mm)(8 mm + 15 mm + 17 mm)

  A = (120 +9(40)) mm² = 480 mm²

The best answer from the choices provided is option B) 56.

Step-by-step explanation: Simply subtract 34 from 90.

Answer:

51.32

Step-by-step explanation:

∠B = arcsin(b·sin(A)a)

= 0.67513 rad = 38.682° = 38°40'56"

∠C = 180° - A - B = 0.89566 rad = 51.318° = 51°19'4"

c = a·sin(C)sin(A) = 31.22499

Answer:

Triangle A

Explanation:

This isn't really an explanation, but I don't really know how to explain. The other answers just aren't correct (They aren't right triangles).

Answer:b=7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(3b−1)=40

(2)(3b)+(2)(−1)=40(Distribute)

6b+−2=40

6b−2=40

Step 2: Add 2 to both sides.

6b−2+2=40+2

6b=42

Step 3: Divide both sides by 6.

6b/6=42/6

b=7

Answer:

But Mars has no magnetosphere, and its atmosphere is over 100 times thinner than Earth's atmosphere. The trip to Mars and the stay on Mars will mean extended radiation exposure. Astronauts will need special habitats, suits, and machines that will protect them from radiation, which otherwise could cause cancer.

Answer/Step-by-step explanation:

Recall: SOHCAHTOA

✔️Sin M = Opp/Hyp

Reference angle = M

Opp = 3√21

Hyp = 15

Sin M = (3√21)/15

Sin M = √21/5

✔️Cos M = Adj/Hyp

Reference angle = M

Adj = 6

Hyp = 15

Cos M = 6/15

Cos M = 2/5

✔️Tan M = Opp/Adj

Reference angle = M

Opp = 3√21

Adj = 6

Tan M = (3√21)/6

Tan M = √21/2

note. It was answered based on the additional information given in the comments (though 41 mm should be 42 mm)

26mm² is area of complex figure.

Answer:

solution:in rectangle

length[l]=6mm

breadth [b]=4mm

area of rectangle=l×b=6×4=20mm²

again in triangle

height[h]=6/2=3mm

base[b]=4mm

area of triangle =1/2 b×h=1/2×3×4=6mm²

total area of composite figure=20mm²+6mm²

=26mm²

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer:

Question one = 35a - 15

Question two = 9

Step-by-step explanation:

Distributive property means to multiply all the numbers inside the parenthesis

by the outside number. 5 x 7a equals 35a and 5 x 3 = 15.

35 x 9 - 315 - 15 = 300

A = 9

Answer:

Since the annual profit for the FIRST YEAR is $322,000 and it increases 21% every year for 26 years, you do so to find the answer to the question.

Step-by-step explanation:

21% per year

26 years

21 x 26 = 546

Now you have to find 546% of 322,000 and add that to 322,000.

546% of 322,000 is 1,758,120.

hope this helped!

Answer:

$216,265,829

Step-by-step explanation:

To find the sum of a geometric series we use the following equation

[tex]a*\frac{1-r^n}{1-r}[/tex]

we have

[tex]322000*\frac{1-1.21^{26}}{1-1.21}\\\\322000*671.633=216265829[/tex]

Answer:

  cot(θ) = 4/5

Step-by-step explanation:

In the polar/rectangular coordinate representation (x, y) ⇔ (r; θ), we know that ...

  (x, y) = (r·cos(θ), r·sin(θ))

From the various trig definitions and identities, we also know that ...

  cot(θ) = cos(θ)/sin(θ) = (x/r)/(y/r) = x/y

For the given (x, y) = (-4, -5), the cotangent is ...

  cot(θ) = -4/-5 = 4/5
