it flew 3.21 meter further

4 meters = 400 centimeters

400-79= 321 centimeters

Jane has 63m ribbon.If she cuts 56m 21cm ribbon from it,what length of ribbon will be left.

marta [7]

Exchange : 63m = 6300 cm; 56m21cm= 5621cm
So the lengths of the ribbon will be left is : 6300 - 5621 = 679cm = 6.79 m

Hope it helps! If it is, Brainliest please!

Evaluate 2/3+3/4 <br> 1and5/12

chubhunter [2.5K]

2/3 + 3/4 = 8/12 + 9/12 = 17/12 = 1 5/12

1 + 5/12 = 12/12 + 5/12 = 17/12 = 1 5/12

2/3 + 3/4 = 1 + 5/12

Write in vertex form<br> f(x)=x^2+12x+34

svp [43]

Answer:

(-6, -2)

Step-by-step explanation:

$f(x) = {x}^{2} + 12x + 34$

$= f(x) = {1x}^{2} + 12x + 34$

= a = 1, b = 12

$= x = - \frac{12}{2 \times 1}$

$= x = - \frac{12}{2}$

= x = -6

$= f(x) = {x}^{2} + 12x + 34.. = - 6$

$= f( - 6) = - 2$

= (-6, -2)

Find the surface area of composite figure. Please help

Ivan

Answer:

The surface area of the composite figure is $410\ m^{2}$

Step-by-step explanation:

we know that

The surface area of the composite figure is equal to the surface area of the rectangular prism of the bottom plus the lateral area o the rectangular prism of the top

so

Step 1

Find the surface area of the rectangular prism of the bottom

The surface area is equal to

$SA=2B+Ph$

Find the area of the base B

$B=10*10=100\ m^{2}$

$P=4*10=40\ m$

$h=3\ m$

substitute

$SA=2(100)+40(3)=320\ m^{2}$

Step 2

Find the lateral area of the rectangular prism of the top

The lateral area is equal to

$LA=Ph$

$P=2*(4+5)=18\ m$

$h=5\ m$

substitute

$LA=18(5)=90\ m^{2}$

Step 3

Find the surface area of the composite figure

$320\ m^{2}+90\ m^{2}=410\ m^{2}$
