Answer:

30, 150, 120, and 60 degrees

Step-by-step explanation:

Since the sum of the interior angles in a quadrilateral is 360 degrees:

y+5y+4y+2y=360

12y=360

y=30

2y=60, 4y=120, 5y=150

Hope this helps!

Step-by-step explanation:

y+5y+ 4y + 2y=360°(sum of a Quadrilateral)

12y=360°

divide both sides by 12

y=30°

5y=(5×30)=150°

4y=(4×30)=120°

2y=(2×30)=60°

How do I find the surface area and volume of the larger figure using that of the smaller figure?

dalvyx [7]

We know that
scale factor=1/8

volume smaller figure=[scale factor]³*volume larger figure
so
volume larger figure=volume smaller figure/[scale factor]³
volume smaller figure=7 km³
volume larger figure=7/[1/8]³----> 7/(1/512)---> 7*512---> 3584 km³

the answer Part a) is
the volume of the larger figure is 3584 km³

surface area smaller figure=[scale factor]²*surface area larger figure
surface area larger figure=surface area smaller figure/[scale factor]²
surface area smaller figure=9 km²
surface area larger figure=9/[1/8]²----> 9/(1/64)---> 9*64---> 576 km²

the answer part b) is
the surface area of the larger figure is 576 km²

A 208-yard-long road is divided into 16 parts of equal length. Mr.Ward paints a 4-yard-long strip in each part. How long is the

Andreas93 [3]

Answer:

Length of unpainted strip of each part of the road = 9 yard

Step-by-step explanation:

Total length of the road = 208 yard

When it is divided into 16 equal parts,

length of each part = $\frac{208}{16}$
