Answer:

14.7 trees

Step-by-step explanation:

First you need to find how many trees she cuts down to build one cabin. So you divide:

10.5/5=2.1

She cuts down 2.1 trees to make one cabin.

Next you multiply:

2.1*7=14.7

Child admission is $5.70 and adult admission is $9.50. Twice as many adult tickets ad child tickets were sold. for a total of $5
makkiz [27]
Let the number of child tickets sold be x, and number of adult tickets be y, then
5.70x + 9.50y = 543.40 . . . (1)
y = 2x . . . (2)

Putting (2) into (1), gives
5.7x + 9.5(2x) = 543.4
5.7x + 19x = 543.4
24.7x = 543.4
x = 543.4/24.7 = 22

Therefore, 22 child tickets were sold.

At what temperature (in k) will the density of this liquid be equal to 1.183 g/cm^3
Kobotan [32]

The temperature (in k) at which the density of this liquid will be equal to 1.183 g/cm³ is; 639.6 K

<h3>How to find the temperature from density?</h3>

We are given the formula for density as;

D = 1.246 g/cm³/(1 + 8.324 * 10⁻⁵ K⁻¹ × T)

Where D is density and T is absolute temperature (In K).

If we want a density of 1.183 g/cm³, then we have;

1.183 = = 1.246 g/cm³/(1 + 8.324 * 10⁻⁵ K⁻¹ × T)

Cross multiply to get;

1.183 + (1.183 * 8.324 * 10⁻⁵ * T) = 1.246

1.183 + 0.985 * 10⁻⁴T= 1.246

0.985 * 10⁻⁴T = 1.246 - 1.183

T = 0.063/( 0.985 * 10⁻⁴)

T = 639.6 K

Pleas help me solve #1 :( <br> Your answer helps so much!!
miskamm [114]

ANSWER

y = 7 \sqrt{2}

x = 7

EXPLANATION

The given triangle has a right angle.

The side opposite to the 45° angle is 7 units.

To find angle x, we use the tangent ratio.

Recall the mnemonics TOA, which means,

\tan(45 \degree)  =  \frac{opposite}{adjacent}

\tan(45 \degree)  =  \frac{7}{x}

1 =  \frac{7}{x}

x = 7

To find y, we use the sine ratio, which means

\sin(45 \degree)  =  \frac{opposite}{hypotenuse}

\sin(45 \degree)  =  \frac{7}{y}

y=  \frac{7}{\sin(45 \degree) }

y=  \frac{7}{ \frac{1}{ \sqrt{2} } }

y = 7 \times  \frac{ \sqrt{2} }{1}

y = 7 \sqrt{2}

An engineering student answered 81 questons correctly ona 90 question test. What percent of the question did she answer correctl
SIZIF [17.4K]

Answer:

correct answer = 90%

Step-by-step explanation:

Let x be the percent of the question did she answer correctly.

Given:

An engineering student answered 81 questions correctly on a 90 question test.

Find the percent of the question did she answer correctly.

Solution:

Percentage formula is given below

% answer =\frac{correct\ answer}{total\ questions}\times 100

% answer =\frac{81}{90}\times 100

% answer =\frac{81\times 100}{90}

% answer =\frac{81\times 10}{9}

% answer =9\times 10

% answer =90

correct answer = 90%

Therefore, she answered 90% correctly.
