Answer:

Yes

Step-by-step explanation:

The formula for area of a triangle is A = (1/2)bh,

For the first triangle we can leave it in general terms, so it's area is

A = (1/2)bh, depending on what b and h are, but it doesn't matter here...

The second triangle has base that is twice the other triangles base.  Bases being multiples of each other is the definition of being proportional so the bases are proportional, an the area of the second triangle is

A = (1/2)(2b)h,   which simplifies to

  A = bh

Comparing the 2 areas, you can see that one has a multiplier of (1/2), so their areas are proportional

Answer:

The balance after 15 year is  $831.25 .

Step-by-step explanation:

Formula

Where P is the principle and r is the rate of interest in the decimal form and t is the time.

As given

Caiden earned $475 from mowing lawns last summer.

He deposited this money in an account that pays an interest rate of 3.8% compounded annually.

Here

P = $475

3.8% is written in the decimal form.

= 0.038

r = 0.038

t = 15 years

Put in the formula

Amount = $831.25

Therefore the balance after 15 year is  $831.25 .

PLEASE HELP!!

First, we need to find the volume of the pan.  We do this by multiplying the length, width, and height together.  This is:

volume=10*12 \frac{1}{2} *2=250 in^{3}

Next, we find the volume of the pieces of bread.  We do this the same way.

volume=2*2 \frac{1}{2}*2=10in^{3}

Finally, we figure out how many times 10 can go into 250.  We do this by dividing 250 by 10.

250/10=25, so Arla can cut 25 pieces of bread.

Write an expression for angle rst.
levacccp [35]

Answer:

∠RST = 6x - 18

Step-by-step explanation:

Since SQ bisects ∠TSR then ∠RSQ = ∠QST = 3x - 9

and ∠RST = ∠RSQ + ∠QST = 3x - 9 + 3x - 9 = 6x - 18
