Answer:

9.65 miles

Step-by-step explanation:

Given:

Final elevation = 8.05 miles

Change in elevation = 1.6 miles

Let Initial elevation which is the elevation before descent = x

Initial elevation - change in = final elevation

(-ve) sign because it was a descent

x - 1.6 = 8.05

x = 8.05 + 1.6

x = 9.65 miles

Hence, elevation before descent is 9.65 miles

Answer:

See below.

Step-by-step explanation:

Adding 2 to both sides will not help solve the equation.

Adding 2 to both sides gives you this:

x^3 = ∛(x-2)

x^3 + 2 =∛(x-2) + 2

Answer:

128 > 4*(x + 7)

Step-by-step explanation:

Given the following data;

Length = 4 meters

Width = x + 7 meters

Area = 128 m²

Mathematically, the area of a rectangle is given by the formula;

Area of rectangle = length * width

Substituting into the formula, we have;

128 > 4*(x + 7)

128 > 4x + 28

128 - 28 > 4x

100 > 4x

Dividing both sides by 4, we have;

25 > x

Answer:

Y = 50 degrees, X = 60 degrees

Step-by-step explanation:

Since we know that the sum of angles in a triangle is 180 degrees, we can find x easily. We already know that the other two angles are 50 and 70, which adds up to 120, and 180 - 120 is equal to 60 degrees, meaning that x is equal to 60 degrees. Next, to find the measure of y, we first know that the sum of angles on a line is equal to 180 degrees, and if we find the other angle on the line by subtracting 60 + 50 from 180, we can find y. 180 - (60 + 50) = 70 degrees, and since 70 + x + y = 180 and x = 60, we know that x = 180 - (70 + 60) = 50. Therefore, y is equal to 50 degrees.

Step-by-step explanation:

Answer:

a) 2nd and 3rd quadrant

b) 143.13° and 36.87°

Step-by-step explanation:

Secant A = 1/cosecant A

sec A = 1/cosA

If Sec A = -5/4

Cos A = 1/(-5/4)

CosA  = -4/5

Since cos A is a negative values, hence the angle A will be in the 2nd and 3rd quadrant

b) If CosA  = -4/5

A = arccos(-0.8)

A = 143.13

A = 180 - 143.13

A = 36.87

Hence the measures of angle A are 143.13° and 36.87°

Question:

Matthew walks 4/10 to mile to Zack's house. Which fraction is equivalent to 4/10?​

Answer:

[tex]Fraction = \frac{2}{5}[/tex]

Step-by-step explanation:

Given

[tex]Fraction = \frac{4}{10}[/tex]

Required

Determine its equivalent

To do this, we simplify the fraction

Divide by 2/2

[tex]Fraction = \frac{4/2}{10/2}[/tex]

[tex]Fraction = \frac{2}{5}[/tex]

Hence, 2/5 is an equivalent fraction

Answer:

median:  6

range:  7

mean:  5.4

Step-by-step explanation:

median is the middle value

range is the highest value minus the smallest value

mean is the total of all values divided by the total data values (174÷32, in this problem)

Answer: C. The answer i got was C

Answer: 904.32 cm^3

Step-by-step explanation:

The formula to finding the volume of a sphere is (V=4/3(3.14)r^3

So in this case it would be (V=4/3(3.14)(6)^3

The radius is half the diameter so that's how I got 6.

The answer after multiplying everything would be 904.32

Answer:

Ratio (r) = 2

n = 7

Step-by-step explanation:

The formula for the sum of the nth term of a G.P is given as:

Sn = a(1-r^n)/(1-r)

Where n = Number of terms

r = Common ratio

The sum of the 1st nth term gp is 127.

Hence:

127 = 1(1-r^n)/(1-r)

The sum of the reciprocal is 127/64

The formula is inverted , hence:

Sn = 1/a(1-r^n)/(1-r)

127/64 = r^(1-n)(1-r^n)/(1-r)

Hence:

1/64 = r^(1-n)

r^(n-1) = 64

r^(n-1) = 2⁶

Hence:

r = 2

Solving for n

n - 1 = 6

n = 6 + 1

n = 7

Therefore:

r = 2

n = 7

Answer:

The difference is

Step-by-step explanation:

Given

Large triangle

[tex]Base = 5cm; Height=9cm[/tex]

Small triangle

[tex]Base = 2cm; Height=6cm[/tex]

See attachment for logo

Required

The difference in their areas

Area is calculated as:

[tex]Area = 0.5 * base * height[/tex]

For the large triangle

[tex]Area = 0.5 * 5cm * 9cm[/tex]

[tex]Area = 22.5cm^2[/tex]

For the small triangle

[tex]Area = 0.5 * 2cm * 6cm[/tex]

[tex]Area = 6cm^2[/tex]

The difference (d) is calculated as:

[tex]d = 22.5cm^2 - 6cm^2[/tex]

[tex]d = 16.5cm^2[/tex]  

Answer:

3/4 meters

Step-by-step explanation:

We can use ratios to solve

8m         2 m

------- = -----------

3m         x m

Using cross products

8*x = 3*2

Divide each side by 8

8x/8 = 6/8

3/4 meters

Answer:

x = 3/4 m

Step-by-step explanation:

Construct two similar right triangles that share an angle of elevation.  The two vertical sides represent the heights of the person and the tree and are 2 m ad 8 m respectively.  The two horizontal sides represent the shadow cast by the person and that cast by the tree, respectively.  Because the triangles are similar, we can write the following equation of ratios:

 8 m       3 m

--------- = --------

 2 m         x

... where x is the length of the shadow cast by the person.

Cross multiplying, we get:

8x = 6m, or x = 6/8 m, or x = 3/4 m

Answer:

Step-by-step explanation:

We have the value of the hypotenuse and we are trying to find out the adjacent. This means we can use cos.

Cos (45) = x/10

10 * Cos (45) = 10 * (√2 / 2)

This should equal to 5√2

Given:

The volume of a cylinder is 95 cubic centimetres.

To find:

The equation that can be used to find h, the height of the cylinder.

Solution:

We know that, the volume of a cylinder is:

[tex]V=\pi r^2h[/tex]

We know that the base of the cylinder is a circle and the area of the circle is [tex]\pi r^2[/tex]. So, the base area of the cylinder is [tex]B=\pi r^2[/tex].

Now, volume of the cylinder is

[tex]V=Bh[/tex]

The volume of a cylinder is 95 cubic centimetres.

[tex]95=Bh[/tex]

[tex]\dfrac{95}{B}=h[/tex]

[tex]h=\dfrac{95}{B}[/tex]

Where B is the base area of the cylinder.

Therefore, the correct option is G.

Answer:

Answer is A. 3 + 1.5 b < 15.

Step-by-step explanation:

Look at the problem carefully. Variable (b) represents books, and it states that the books weigh 1.5 lbs each. So you add her lunch (1 lb) and her shoes (2 lbs) to get 3 lbs. Once you add it together, it's less than (<) 15 lbs.

I tried to make this as understandable as possible, hope it helps.

Answer:

Step-by-step explanation:

Find the unit rate of Sugar. Then find the cost of  2.5 Kg sugar

1 kg sugar =36 ÷ 4.5

                [tex]= \frac{36*10}{4.5*10}= \frac{360}{45}\\\\= 8[/tex]

2.5 kg of sugar= 2.5 * 8 = 20.0 = R 20

Answer:

Kg Rupee

4.5 = 36

2.5 = ?

Therefore, 2.5*36/4.5

Therefore, 25*36*10/45*10

Therefore, 25*36/45

Therefore, 5*5*36/9*5

Therefore, 5*36/9

Therefore, 5*3*2*3*2/3*3

Therefore, 5*2*2

Therefore, 10*2

Therefore, 20

2.5 kg =20 Rupees

Answer:

The first number is 14

The second number is -3

Step-by-step explanation:

x + 2y = 8

2x + y = 25

Solving simultaneously,

2x + 4y = 16

2x + y = 25

On subtracting, we have

3y = -9

y = -3

Going to substitute for y, we have

x + 2(-3) = 8

x - 6 = 8

x = 14
