Answer:

The price of travel insurance for a duration of 4 days is 19 pounds

Step-by-step explanation:

The cost calculation for insurance is governed by the formula T = 3.5n + 5, where T represents the cost in pounds for n days of coverage.

This formula involves two variables: T, the insurance cost, and n, the duration in days.

To calculate the amount for 4 days, we assess:

T = 3.5n + 5

T = 3.5 × 4 + 5

T = 14 + 5

T = 19 pounds

The price of travel insurance for a duration of 4 days is 19 pounds

∠ROT=160°

∠SOT=100°

Now we calculate ∠SOR as follows: ∠SOR = ∠ROT - ∠SOT

∠SOR = 160° - 100°

∠SOR = 60°

It is stated that the angles ROQ, QOS, and POT all have the same measure.

Thus, ∠SOQ + ∠QOR = 60°

Since ∠SOQ equals ∠QOR, we can express this as:

2∠SOQ = 60°

From which we find ∠SOQ = 60° ÷ 2

∠SOQ = 30°

Also, ∠POT = ∠SOQ = ∠ROQ = 30°

2. Santiago wants the lateral surfaces of the
Inessa [12570]

Answer:

Red paint will cover 262 square feet

of the ramp.

Step-by-step explanation:

The lateral surface area represents the surface area of the sides of the ramp without including the top and bottom surfaces

This ramp has three surfaces

The two sides are triangular with dimensions of length 20 and height 8.5

The back consists of a rectangular shape with length 12 and height 8.5

Step 1: Calculating the Area of Triangle

The area of the triangular side = \frac{1}{2} length \times height

The area of the triangle = \frac{1}{2} (20 \times 8.5)

The area of the triangle = \frac{170}{2}    

Thus, the area of the triangle = 85 square feet

Area of both triangles = 85 \times 2  =  170

Step 2: Finding the Area of Rectangle

Area of rectangle = length \times height

therefore,

Area of the rectangular back = 12 \times 8.5 = 102  square feet

Step 3: Calculating the total lateral surface area

Overall Lateral Surface Area

= Area of triangles + Area of Rectangle

= 272 square feet

This question is quite lengthy, so I will offer a brief overview. To find your x-value, set y to 0 in the given equation.

2x + 3y = 1470

2x + 3(0) = 1470

2x = 1470

x = 735

Thus, your farthest point on the x-axis is (735,0).

Now, repeat for y.

2x + 3y = 1470.

2(0) + 3y = 1470

3y= 1470

y= 490

Your highest point thus is (0,490).

After plotting both points, connect them with a straight line to illustrate your graph.

Alex can ski 960 meters in 5 minutes. If his skiing speed is increased by 20 m/min, how many meters can he cover in 10 minutes?
tester [12383]
Initially, we need to determine how fast he skis in a minute without considering any speed increase.
To do that, we'll divide the total distance by the time.
960 divided by 5 equals 192.
Therefore, his speed is 192 meters per second.
Now, let's add 20 to this figure.
192 plus 20 equals 212.
Now, to calculate how far he can travel in 10 minutes, we multiply 212 by 10.
212 times 10 equals 2120.
Thus, Alex can cover 2120 meters in 10 minutes.

Suri's age is 4 less than 3 times her cousin's age. Suri is 17 years old. Which method can be used to find c, her cousin's age?
zzz [12365]

Answer:

7 years

Step-by-step explanation:

Suri is 17 years old.

Her cousin's age is c.

Suri's age is stated to be 4 less than 3 times her cousin’s age.

This means we take 3 times her cousin’s age and subtract 4.

17 = 3c - 4

We now need to solve for c, which represents her cousin's age.

Add 4 to each side:

17 + 4 = 3c - 4 + 4

17 + 4 = 3c

21 = 3c

Now divide both sides by 3:

21/3 = 3c/3

7 = c

Thus,

Her cousin is 7 years old.
