Answer 1

Answer:

22.44 cm^2

Step-by-step explanation:

There's four triangles and one square so lets start with the triangles.

2.24×3÷2=3.36

That's the area of one triangle, there's four so:

3.36×4=13.44

Then the square!

3×3=9

13.44+9=22.44 cm^2

I'm not sure if this is the standard way since I didn't learn about pyramids so I used the area stuff, so sorry if its not correct.

Have a nice day!

rewrite the equation 12x=13-x^2

Answers

Answer:

x^2+12x-13 = 0

Step-by-step explanation:

12x=13-x^2

=>12x+x^2=13-x^2+x^2

=>x^2+12x-13 = 13-13

=> x^2+12x-13 = 0

Answer:

x² + 12x - 13 = 0

Step-by-step explanation:

12x = 13 - x²

the standard form of an equation is written starting from the variable of the highest degree to the lowest. Hence after rearranging;

0 = 13 - x² - 12x

0 = -x² - 12x + 13

In an equation, the highest degree of a variable should preferably be postive hence the equation to the left side to remove the negative sign:

x² + 12x - 13 = 0

Why would the velocity of a river affect its ability to erode sediment?

Answers

The power of a river to cause erosion and carry sediment depends on several factors. A rivers slope, volume of flow, and the shape of its stream bed all affect how fast the river flows and how much sediment it can erode. ... When a river slows down, it drops its sediment load.

The velocity of the river that impact the capability for eroding the sediment should be explained below.

Impact on the velocity of a river:

In the case when the slope should be considered too gentle and here the velocity should be too slow for transporting the sediments that being supplied via weathering and erosion also the sediments should be piled up.

It rised  the gradient that resulted the water to flow quickly that increased the erosion and transport due to which it decreased the gradient.

how do you round to two decimal places ?? i just have the normal answers btw. asap!! :(

Answers

Answer:

Step-by-step explanation:

Look at the 3rd decimal digit (the digit after the hundredths).

if it is the digit is less than 5 then round the number down by taking away the decimal point of the number after the 2nd decimal place;However if  it is 5 or more then round the number up by adding one on to the hundredths digit and removing the rest of the decimal part of the number after it

For example,4.749 rounds up to 4.75 because the 3rd decimal digit is a 9.

Write an equation for the line parallel to the given line that contains C.
C(1,4)​; y=−3x+1

Answers

Answer:The equation of a line is y = mx + b where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. (Remember that the slope is the steepness  of a line and the y-intercept is the point where the line intersects  the y-axis. The x- and y-coordinates are values of the points on the line of y = 3x - 1.)

Step-by-step explanation:

In the right triangle shown, m\angle Y = 30\degreem∠Y=30°m, angle, Y, equals, 30, degree and XY= 6XY=6X, Y, equals, 6.

YZ = 6.93

Step-by-step explanation:

Find the complete question attached

From the diagram, we are to look for YZ

Given the following

XY = adjacent = 6

measure of m<Y = 30degrees

Required

YZ = hypotenuse

Using the SOH CAH TOA identity

Cos theta = adjacent/hypotenuse

Cos 30 = XY/YZ

Cos 30 = 6/x

x = 6/cos30

x = 6/0.8660

x = 6.93

Hence the length of YZ is 6.93
