Answer:

2 hours and 5 minutes.

Step-by-step explanation:

2 hours is 60mins+60mins which is equal to 120mins and then the extra 5mins

Hilary studied for a total of 2 hours and 5 minutes this week.

If Hilary studied for 25 minutes each day for five days this week, we can calculate the total study time by multiplying the number of minutes studied per day (25) by the number of days (5):

25 minutes/day × 5 days = 125 minutes

To convert this to hours and minutes, we need to divide the total minutes by 60 (since there are 60 minutes in an hour) to get the number of hours and find the remainder as minutes.

125 minutes ÷ 60 = 2 hours and 5 minutes

Therefore, Hilary studied for a total of 2 hours and 5 minutes this week.

Answer:

Step-by-step explanation:

The new coordinates of A is (-12,8)

To dilate something in the coordinate plane, multiply each coordinate by the scale factor. This is called mapping.

For any dilation the mapping will be (x,y) → (kx,ky).

Convert the point (x, y) to (-y, x) in order to rotate 90 degrees counter clockwise.

The given point is A(-4 ,6) ,after it has been rotated the new coordinates are A(-6,-4)

After reflecting it over x axis the new coordinated will be (-6,4)

Then dilating it with a scale factor of 2

The new coordinates of A is (-12,8)

Answer:

The radius is 8.

Step-by-step explanation:

Because OA is a radius and AB is a tangent, Angle A is a right angle. So you can use Pythagorean theorem (shortcut Pythagorean triple)

OA^2 + 15^2 = 17^2

OA^2 + 225 = 289

OA^2 = 64

OA = 8

OA is a radius, the radius = 8

Area of figure :

Answer:

(a) = 37π/180 radians

(b) = 37°

Step-by-step explanation:

Converting km/h ⇒ m/s :

⇒ 54 km/h x 5/18

⇒ 3 x 5

⇒ 15 m/s

===============================================================

Formula to calculate the angle :

⇒ tanθ = v/r

⇒ tanθ = (15 m/s)/(20 m)

⇒ θ = tan⁻¹ (0.75)

⇒ θ = 37°

=============================================================

Converting to radians :

⇒ Radian measure = Angle measure × π/180°

⇒ Radian measure = 37° × π/180°

⇒ Radian measure = 37π/180 radians

=============================================================

Solutions :

(a) = 37π/180 radians

The magnitude of the force per unit length between the wires is [tex]3 \times 10^{-5} N/m[/tex].

In a wire carrying a current I 2, the force that each wire feels due to the presence of the other depends on the distance between them and the magnitude of the currents.

Force per unit length = magnetic permeability * (current 1) * (current 2) / (2 π distance between the wires).

The below expression for the force per unit length.

Moreover, before using the below formula we have to change the unit centimeter into a meter. So, we just divide the centimeter by 100.

[tex]\rm \dfrac{Force}{length}=\dfrac{u_0 \times i _1 \times i_2}{2\pi d}\\\\\dfrac{Force}{length}=\dfrac{u_0 \times i _1 \times i_2}{2\pi d}\\\\Where; \ \mu_0 = 4\pi \times 10^{-7} , i_13 . \ i_2 = 3 \ d=0.06[/tex]

Substitute all the values in the formula

[tex]\rm\dfrac{Force}{length}=\dfrac{u_0 \times i _1 \times i_2}{2\pi d}\\\\Where; \ \mu_0 = 4\pi \times 10^{-7} , i_13 . \ i_2 = 3 \ d=0.06\\\\ \dfrac{Force}{length}=\dfrac{4\pi \times 10^{-7} \times 3 \times3}{2\pi \times 0.06}\\\\ \dfrac{Force}{length}= 3 \times 10^{-5} N/m[/tex]

Hence, the magnitude of the force per unit length between the wires is [tex]3 \times 10^{-5} N/m[/tex].

The surface area of the box, in square feet, that Zoe decorates is 430.35 square feet

To determine the surface area from the net of the box, we simply calculate the area of each shape.

From the given figure, we have the following shapes and dimensions:

The area is then calculated using:

Area = Areas of the rectangle + Area of the triangle

So, we have:

Area = 15 * 12 + 13.89 * 15 + 0.5 * 12 * 7

Evaluate the sum of products

Area = 430.35

Hence, the surface area of the box, in square feet, that Zoe decorates is 430.35 square feet

Answer:

Step-by-step explanation:

The value of the given trigonometric function is 1.1547.

The main trigonometric ratios are: sinβ, cosβ and tg β. From these ratios, you can calculate other trigonometric ratios such as sec β, cossec β and cotg β.

These ratios help you find the angles and the sides of a rectangle triangle.

The question asks [tex]\frac{2 *sin(30)}{cos (30}[/tex], for the angle 30° you have sin=1/2 and cos= [tex]\frac{\sqrt{3} }{2}[/tex].

Thus,

[tex]\frac{2 *sin(30)}{cos (30}=\frac{2 *\frac{1}{2} }{\frac{\sqrt{3} }{2} }=\frac{1}{\frac{\sqrt{3} }{2} }= \frac{2}{\sqrt{3} } =\frac{2\sqrt{3} }{3}=1.1547[/tex]
