Answer:

Step-by-step explanation:

3 2/4+ 2 3/4+ 2 3/4+ 2 1/4+ 1 1/4+ 1

first add the whole numbers so 3+2+2+2+1+2=12

then we are left with the fractions. 11/4 divides into 2 with a remainder of three so we add it to the top.

From here we have 2/4+3/4+3/4+1/4+3/4

add them together and we get 12/4=3. Then add back our whole numbes to get 12+3=15

Consider triangle abc what is the value of y in the triangle

Yakvenalex [24]

Answer:

y = 50

Step-by-step explanation:

All triangle angles add up to 180 degrees.

To set this equation up, you need to add everything given in the triangle and set it equal to 180:

y + y + 80 = 180

Add like terms:

2y + 80 = 180

Subtract 80 from both sides:

2y + 80 = 180

- 80 - 80

___________

2y = 100

Divide both sides by 2:

y = 50

If you're unsure, you can plug in the 50 for y:

y + y + 80 = 180

50 + 50 + 80 = 180

100 + 80 = 180

180 = 180

How would I do this? What would it be?

Vinvika [58]

Step-by-step explanation:

Since AE is the bisector of angle BAC,so angle BAE and Angle CAE is equal. Here Angle CAE and Angle EAC is same.

therefore,

m(Angle BAE)=m(Angle EAC)

$x + 30 = 3x - 10$

or, 2x=40

or, x=20

Hence,

m(Angle EAC)=

$3x - 10$

$(3 \times 20) - 10 = 60 - 10 = 50$

The two solids are similar and the ratio between the lengths of their edges is 2:7 what is the ratio of their surface areas?

vovangra [49]

Answer:

The ratio of their surface areas is $\frac{4}{49}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor

In this problem the scale factor is equal to the ratio $\frac{2}{7}$

and

Remember that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

therefore

In this problem the ratio of their surface areas is $(\frac{2}{7})^{2}=\frac{4}{49}$

ANYONE GOOD AT MATH? PLEASE PLEASE PLEASE SOMEONE HELP ME :(

Mumz [18]

Answer:

The parent function is $f(x)=a(x-h)^{2} +k$

That Parabola's equation is $f(x)=x^{2}$

Step-by-step explanation:

I can't really explain much, but the top equation is a formula for all equations for a parabola. h and k are the x and y-values of the vertex. a is, well, a.

How did I find the equation of the parabola? Simple. Since the vertex is on the origin, h and k are 0. Also, because it intercepts (2,4) and (1,1), a=1.
