Answer:

43.43

Step-by-step explanation:

Convert 25 minutes to decimal degrees by 25/60 = 0.416...=0.42

Convert 36 seconds to decimal degrees by 36/3600 (There are 3600 seconds in a degree) = 0.01

Now you have:

43 degrees, 0.42 degrees. and 0.01 degrees.

Add them all to get 43.43

4 times 3 is 12. Simple multiplication. 3 times 3 is 9. WOW

Answer:

9 hours

The average rate of snowfall here is 4 inches per/hour, so that means we have to multiply the amount of hours by itself to get the answer.

3 × 3 = 9(with 12 inches of snow fell total, equaling 1 foot)

Answer:

d.45 sq.ft

Step-by-step explanation:

Surface are i.e. Total surface area of square pyramid = a^2 + 2al

where a^2 is area of base

a is side of base

l is slant height

by the figure

a=3ft

a^2 = a×a

=3×3

=9ft

l=6ft

Surface area = a^2+2al

=9+2×3×6

=9+36

=45 sq.ft

Answer:

x = 9

Step-by-step explanation:

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

Here the exterior angles has a measure of 10x + 58° while its opposite interior angles have measures of 6x + 56° and 38°

If an exterior angle of a triangle is equal to the sum of the opposite interior angles then 10x + 58 = 6x + 56 + 38  

we now solve for x

10x + 58 = 6x + 56 + 38  

==> combine like terms

10x + 58 = 6x + 94

==> subtract 58 from both sides

10x = 6x + 36

==> subtract 6x from both sides

4x = 36

==> divide both sides by 4

x = 9

and we are done! :)

Answer:

x = 9

Step-by-step explanation:

The sum of all the interior angles of a triangle = 180 degrees

one of the angles of the triangle's interior is blank, so to find it we can subtract the exterior angle measure next to it from 180 degrees (a straight line)

38 + (6x + 56) + (180 - (10x + 58)) = 180

Now, we can do our best to simplify and combine like terms:

[38 + 56 + (180 - 58)] + [6x - 10x] = 180

216 - 4x = 180

Now we can subtract 180 from both sides...

36 - 4x = 0

And then add 4x to both sides...

36 = 4x

Now we've manged to isolate x, all that's left is to divide both sides by 4

9 = x

Or

x = 9

The cosine is the ratio of hypotenuse and base. Then the measure of the angle ∠L will be 60°.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The right-angle triangle is given below.

The length of the hypotenuse is 16 and the base length is 5.

Then the measure of the angle ∠L will be

cos L = 5 / 10

Answer:

248

Step-by-step explanation:

Consecutive angles of a parallelogram are supplementary.

56 + y = 180

y = 180-56

y =124

The opposite angles of a parallelogram are equal.

x = y = 124

x+y = 124+124

      =248

Answer:

x + y = 248

Step-by-step explanation:

consecutive angles in a parallelogram sum to 180°

opposite angles are congruent

x + 56° = 180° ( subtract 56° from both sides )

x = 124°

then

y = x = 124 , so

x + y = 124 + 124 = 248

Rina Take home pay is $457.20

The basic salary divided by the Gross salary is multiplied by 100. The result is the percentage of gross salary.

Given that:

gross salary = $624

14% income tax = 624* 0.14 = $87.36

group health plan = $4.25

Company retirement = 624 * 0.060 =$37.44

Social Security = 624 * 0.0605 = $37.752

Home pay= 624 - 87.36 - 4.25 - 37.44- 37.752

= 457.198

Her take home pay is $457.198

if she gets a $35 raise per pay period,

So, new gross salary would be,

= $624 + $35

= $659.

Again, we have

14% Income tax = 659 * 0.14 = $92.26

Group health plan = $4.25

Company retirement = 659 * 0.060 = $39.54

Social Security = 695* 0.0605  = $39.8695

Home take pay,

=659-39.8695 - 45.825 - 39.54-92.26

=441.5055

Her take home pay is $441.5055

Answer:

z = 7/3 is extraneous.

Step-by-step explanation:

√(z^2+8) = 1 - 2z

z^2 + 8 = (1 - 2z)^2

z^2 + 8 = 1 -4z + 4z^2

3z^2 - 4z - 7 = 0

3z^2 + 3z - 7z - 7 = 0

3z(z + 1) - 7(z + 1) = 0

(3z - 7)(z + 1) = 0

3z = 7, z = -1

z = 7/3, -1.

One of these might be extraneous.

Checking:

√(z^2+8) = 1 - 2z, if z = -1:

√(1 + 8) = 3, -3

1 - 2(-1) = 3.    So its not z = -1

if z = 7/3

√((7/3)^2 + 8) = 13.44

1 - 2(7/3) = -3.66

So its z = 7/3

Answer:

[tex]z=\dfrac{7}{3}[/tex]

Step-by-step explanation:

Given equation:

[tex]\sqrt{z^2+8}=1-2z[/tex]

Square both sides:

[tex]\implies (\sqrt{z^2+8})^2=(1-2z)^2[/tex]

[tex]\implies z^2+8=1-4z+4z^2[/tex]

Subtract [tex]z^2[/tex] from both sides:

[tex]\implies 8=1-4z+3z^2[/tex]

Subtract 8 from both sides:

[tex]\implies 0=-7-4z+3z^2[/tex]

[tex]\implies 3z^2-4z-7=0[/tex]

Rewrite the middle term:

[tex]\implies 3z^2+3z-7z-7=0[/tex]

Factor the first two terms and the last two terms separately:

[tex]\implies 3z(z+1)-7(z+1)=0[/tex]

Factor out the common term [tex](z+1)[/tex]:

[tex]\implies (3z-7)(z+1)=0[/tex]

Therefore:

[tex]\implies (z+1)=0 \implies z=-1[/tex]

[tex]\implies (3z-7)=0 \implies z=\dfrac{7}{3}[/tex]

To find the extraneous solution (the root that is not a root of the original equation), enter the two found values of z into the original equation:

[tex]\begin{aligned}z=-1\implies \sqrt{(-1)^2+8}&=1-2(-1)\\\implies 3&=3\implies \textsf{true}\\\end{aligned}[/tex]

[tex]\begin{aligned}z=\dfrac{7}{3} \implies \sqrt{\left(\frac{7}{3}\right)^2+8}&=1-2\left(\frac{7}{3}\right)\\\implies \dfrac{11}{3} &=-\dfrac{11}{3}\implies \textsf{false}\end{aligned}[/tex]

[tex]\textsf{As}\: \dfrac{11}{3} \neq -\dfrac{11}{3}\:\textsf{then}\: z=\dfrac{7}{3}\:\textsf{is the extraneous solution}[/tex]

Step-by-step explanation:

the answer is 17,202 feet

The bird (B) from its nest (N) is 17202 ft.

Trigonometric functions defined as the functions which show the relationship between angle and sides of a right-angled triangle.

This is very obviously a right triangle problem.

Side BO is the hypotenuse of the triangle, measuring 21000.

Side BN is the side adjacent to the given angle B, 35 degrees.

This is the cosine ratio:

cos∅ = adj/hyp

substitute the values

cos35° = x/21000 and solving for x:

21000.cos(35°) = x

x = 17202.19 or, rounded as we need:

x = 17202

Hence, the bird (B) from its nest (N) is 17202 ft

We can solve for angle HKG by using supplementary angles. The angle next to it and itself will add up to 180 degrees, as they are on a straight line.

[tex]120 + ?=180[/tex]

[tex]?=60[/tex]

Angle HKG is 60 degrees.

---

Now, we also know that in triangles, the angles are 180 degrees. We can add up all the angles and find x:

[tex]60+(6x-10)+(2x+10)=180[/tex]

Remove parenthesis:

[tex]60+6x-10+2x+10=180[/tex]

Add like terms:

[tex]8x+60=180[/tex]

Subtract 60 from both sides:

[tex]8x=120[/tex]

Divide both sides by 8:

[tex]x=15[/tex]

We have more supplementary angles. We can find angle JHG:

[tex]?+72=180[/tex]

[tex]?=108[/tex]

---

Now add up the interior angles of the triangle:

[tex]4x-2+3x+4+108=180[/tex]

Add like terms:

[tex]7x+110=180[/tex]

Subtract 110 from both sides:

[tex]7x=70[/tex]

Divide both sides by 7:

[tex]x=10[/tex]

We have more supplementary angles. We can find angle BDC:

[tex]?+111=180[/tex]

[tex]?=69[/tex]

---

Now add up the interior angles of the triangle:

[tex]69+7x+5+8x-14=180[/tex]

Add like terms:

[tex]60+15x=180[/tex]

Subtract 60 from both sides:

[tex]15x=120[/tex]

Divide both sides by 15:

[tex]x=8[/tex]
