1=5-4+3-2-1 pls help me i need to turn this and

Let the number be x

We use addiition sign

The expression is x+15

1. 1 hour = 60 minutes

We convert 3 hours and 25 minutes to minute : 3 x 60 + 25 = 205 (minutes). Since 205 < 230, it took longer to get home than getting to the beach.

2. (Same convertion)

5 hours and 10 minutes = 5 x 60 + 10 = 310 (minutes)

So, the last day rained longer than the day before it.

3. 1 day = 24 hours.

We convert 3 days to hours : 3 x 24 = 72 (hours)

Since 72 > 68, Wendy's family lost their power longer than their neighbors.

4. 1 minute = 60 seconds

Convert 2 minutes and 2 seconds to seconds : 2 x 60 + 2 = 122 (seconds)

Since 122 > 121, it means Paul took longer to finish his race, which mean Jeff finished first (Rip Paul)

5.

Question : Bob bought 2 pizzas for him and his friend, Kevin. They both ate 1 pizza. Bob finished his pizza in 6 minutes and 45 seconds. Kevin finished his pizza in 400 seconds. Who finished first?

Solution : Convert 6 minutes and 45 seconds to seconds : 6 x 60 + 45 = 405 (seconds)

Since 405 > 400, Bob took longer to finish his pizza -> Kevin finished first.

Answer: B

Step-by-step explanation:

In order to isolate 'x', we can use the number 'e' to cancel the natural log. The 'e' will cancel the natural log because they are inverse to each other:

[tex]e^l^n^(^x^)=e^-^3[/tex]

[tex]x=e^-^3=\frac{1}{e^3} =0.049787[/tex]

Answer:

B

Answer:

6in³

Step-by-step explanation:

get the volume by the formula: L x W x H

L = Length

W = Width

H = Height

there are 3 units required to know for getting the volume, if that's true, then, do the inverse operation of finding the volume. That can be done by using the formula:

a= edge

Solving for a

a=V⅓=216⅓=6

So each of the Cube shaped Fish Tank is 6in³

to find out if  the answer is right or wrong we have to do

6x6=36

36x6=216

So the answer is right!

Answer:

60,60,60

Step-by-step explanation:

The angle measures for the triangle is 60, 60 and 60.

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

We have,

The measure of three sides are 6 ,6 and 6.

Now, we know a triangle whose three sides are equal is called as Equilateral Triangle.

Also, three angles are Equal.

Using Angle Sum property

x + x + x = 180

3x= 180

x= 60

Thus, the measure of three angles are 60, 60 and 60.

Answer:

6x-3

Step-by-step explanation:

Answer:

Step-by-step explanation:

I'll give you a guide — use the formula

[tex]y = mx + b[/tex]

For Question 1, [tex]y = \frac{2}{3}x + 2[/tex]

[tex]y = mx + b[/tex]

So,  m = [tex]\frac{2}{3}[/tex]  and  b = 2

For question 3,

[tex]y = mx + b[/tex]

if  m = [tex]\frac{1}{3}[/tex]  and  b = 3

[tex]y = \frac{1}{3}x + 3[/tex]

For the graphs, You label the center as 0, and go up/down 1 right to left and up down

You use every number on the x-axis (horizontal left-right line) and put it in your equation (e.g. [tex]y = \frac{2}{3}x + 2[/tex]) to get the value for the y-axis.

Answer:

Step-by-step explanation:

[tex]2\sin^2 x =\sin x \\\\\implies 2 \sin^2 x - \sin x=0\\\\\implies \sin x(2 \sin x -1) =0\\\\\implies \sin x = 0~~\text{or}~~ 2 \sin x -1 =0\\\\\implies \sin x = 0~~ \text{or}~ ~ \sin x = \dfrac 12\\\\\text{For}~~ \sin x = 0\\\\x=n\pi \\\\\text{In the interval,}~~[0, 2\pi)\\\\x=0, \pi\\\\\text{For}~~ \sin x = \dfrac 12\\\\x=n\pi+(-1)^n \dfrac{\pi}6 \\\\\text{In the interval,}~~[0, 2\pi)\\\\x=\dfrac{\pi}6,~ \dfrac{5\pi}6\\\\\text{Hence,}~ x = 0,~\pi,~ \dfrac{\pi}6, ~\dfrac{5 \pi}6[/tex]

Answer:

[tex]x=0, \dfrac{\pi}{6},\dfrac{5\pi}{6},\pi \:\sf(for\:the\:given\:interval)[/tex]

Step-by-step explanation:

given interval [0, 2π) = 0 ≤ x < 2π

[tex]2\sin^2(x)=\sin(x)[/tex]

subtract sin(x) from both sides:

[tex]\implies 2\sin^2(x)-\sin(x)=0[/tex]

factor:

[tex]\implies \sin(x)[2\sin(x)-1]=0[/tex]

[tex]\sin(x)=0[/tex]

[tex]\implies x=0 \pm2 \pi n, \pi \pm2 \pi n[/tex]

[tex]\implies x=0, \pi \:\sf(for\:the\:given\:interval)[/tex]

[tex]2\sin(x)-1=0[/tex]

[tex]\implies \sin(x)=\dfrac12[/tex]

[tex]\implies x=\dfrac{\pi}{6} \pm2 \pi n, \dfrac{5\pi}{6} \pm2 \pi n[/tex]

[tex]\implies x=\dfrac{\pi}{6},\dfrac{5\pi}{6}\:\sf(for\:the\:given\:interval)[/tex]

Final solution:

[tex]x=0, \dfrac{\pi}{6},\dfrac{5\pi}{6},\pi \:\sf(for\:the\:given\:interval)[/tex]

The area of the rectangle is the product of its base and height

The height of the rectangle is 4x - 2 units

The given parameters are:

Area = 4x^2 - 2x

Base = x

The area of the rectangle is:

Area = Base * Height

This gives

4x^2 - 2x = x * Height

Divide through by x

4x - 2 = Height

Rewrite as:

Height = 4x - 2

Hence, the height of the rectangle is 4x - 2 units

The set of transformation that has been performed on triangle ABC

to form triangle A'B'C' is " Dilation by a scale factor of 2 followed by

reflection about the x-axis " ⇒ 2nd answer

Step-by-step explanation:

Lets revise some important rules

The corresponding sides of similar triangles have constant ratio

Dilation makes a triangle and its image similar

Reflection about x-axis change the sign of the y-coordinate of a point after reflected about the x-axis

Δ ABC and Δ A'B'C are similar after set of transformations has been

performed on Δ ABC to form Δ A'B'C'

∵ The vertices of triangle ABC are:

A = (-2 , -1) , B = (0 , 0) , C = (1 , -3)

∵ The vertices of triangle A'B'C' are:

A' = (-4 , 2) , B' = (0 , 0) , C' = (2 , 6)

∵ x-coordinate of point A = -2 and x-coordinate of point A' = -4

∵ y-coordinate of point A = -1 and y-coordinate of point A' = 2

∵ x-coordinate of point B = 0 and x-coordinate of point B' = 0

∵ y-coordinate of point B = 0 and y-coordinate of point B' = 0

∵ x-coordinate of point C = 1 and x-coordinate of point C' = 2

∵ y-coordinate of point C = -3 and y-coordinate of point C' = 6

∵ Each coordinate of the vertices A , B , C is multiplied by 2 to give

 the coordinates of the of the vertices A' , B' , C'

∴ Δ ABC is dilated by scale factor of 2

∵ The signs of y-coordinates of the vertices A , B , C is opposite to

  the signs of y-coordinates of the of the vertices A' , B' , C'

∴ Δ ABC is reflected about the x-axis

The set of transformation that has been performed on triangle ABC

to form triangle A'B'C' is " Dilation by a scale factor of 2 followed by

reflection about the x-axis "
