In the figure, tx is perpendicular to line RS.this means we can use the pythagorean theorem to determine RX length the long way or simply apply the theorem that each divided triangle becomes a 30-60-90 angle. If opposite to 60 deg is equal to 6 units, then the side's length is equal to 2*6/sq rt 3 or equal to 6.93 units. The answer is half of this equal to 3.47 units.

Students at Maple school earned $708 selling candles. They want to accumulate $2000 for a club trio. What percent of their goal

Sholpan [36]

Answer:

<u>The correct answer is 35.4%</u>

Step-by-step explanation:

Let's check the information provided in the question:

Savings goal = US$ 2,000 for the club trip

Earnings for the candles selling = US$ 708

For calculating the accumulated percentage, we can do it this way:

Accumulated percentage = Earnings / Savings goal

Accumulated percentage = 708 / 2,000 * 100

Accumulated percentage = 0.354 * 100

<u>Accumulated percentage = 35.4%</u>

<u>Students at Maple School has accumulated 35.4% of their savings goal with the candles selling.</u>

If 2 apple and 5 bananas cost 4.20 dollars and 3 apples and 4 bananas coke 4.So dollars what is the price of a apple and banana

e-lub [12.9K]

Answer:

An apple costs $0.45 and a banana costs $0.66.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

An apple costs x.

A banana costs y.

2 apple and 5 bananas cost 4.20 dollars

This means that:

$2x + 5y = 4.2$

So

$2x = 4.2 - 5y$

$x = 2.1 - 2.5y$

3 apples and 4 bananas cost 4.

This means that:

$3x + 4y = 4$

Since $x = 2.1 - 2.5y$

$3(2.1 - 2.5y) + 4y = 4$

$6.3 - 7.5y + 4y = 4$

$3.5y = 2.3$

$y = \frac{2.3}{3.5}$

$y = 0.66$

Then:

$x = 2.1 - 2.5(0.66) = 0.45$

An apple costs $0.45 and a banana costs $0.66.

Approximate the area under the curve over the specified interval by using the indicated number of subintervals (or rectangles) a

RideAnS [48]

Split up [1, 3] into 4 subintervals:

[1, 3/2], [3/2, 2], [2, 5/2], [5/2, 3]

each with length (3 - 1)/2 = 1/2.

The right endpoints $r_i$ are {3/2, 2, 5/2, 3}, which we can index by the sequence

$r_i=1+\dfrac i2$

with $1\le i\le4$ .

Evaluating the function at the right endpoints gives the sampling points $f(r_i)$ , {27/4, 5, 11/4, 0}.

Then the area is approximated by

$\displaystyle\int_1^3f(x)\,\mathrm dx\approx\frac12\sum_{i=1}^4f(r_i)=\frac12\left(\frac{27}4+5+\frac{11}4+0\right)=\boxed{\frac{29}4}$
