Set up a ratio to find the number of pages read in 80 minutes:

40 pages/ 50 minutes = x pages/ 80 minutes

Cross multiply:

50x = 3200

Divide both sides by 50:

X = 3200/50

X = 64

He will read 64 pages in 80 minutes.

200 -64 = 136

There will be 136 pages left.

Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks. At a historical la

Alborosie

Answer:

The number of candles will hold 2 candles

And large candle holder will hold 6 candles.

Step-by-step explanation:

Let the number of candles small candle holder have x

And the number of candles large candle holder have y

So, according to the information given in the question:

17 small candle holders means 17 x

and 2 large candle holders means 2y

using a total of 46 candles means $17x+2y=46$ (1)

Similarly, 8 small candle holders and 2 large candle holders, for a total of 28 candles gives:

$8x+2y=28$ (2)

We will solve equation (1) and (2) by elimination method:

Subtractijng the two equations we get:

$9x=18$

$\Rightarrow x=2$

Substitute x=2 in equation(2) we get: $8(2)+2y=28$

$2y=12$

$\Rightarrow y=6$

So, the number of candles will hold 2 candles

And large candle holder will hold 6 candles.

PLEASE HELP!!!

Answer:

Both the parts of this question require the use of the "Intersecting Secant-Tangent Theorem".

Part A

The definition of the Intersecting Secant-Tangent Theorem is:

"If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment."

This, when applied to our case becomes, "The length of the secant RT, times its external segment, ST, equals the square of the tangent segment TU".

Mathematically, it can be written as:

Part B

It is given that RT = 9 in. and ST = 4 in. Thus, it is definitely possible to find the value of the length TU and it can be found using the Intersecting Secant-Tangent Theorem as:

Thus,

Thus the length of TU=6 inches
