Answer:

? = 14

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp /adj

tan ? = 8/33

Taking the inverse tan of each side

tan ^-1 ( tan ?) = tan ^-1 ( 8/33)

? =13.62699

To the nearest degree

? = 14

Tell me the y-intercept of the line: 2x - 3y = 9

butalik [34]

Answer:

y-intercept: (0,-3)

Step-by-step explanation:

Y-intercepts mean that the x-value has to be equal to 0. When plugging in 0 for the x-value, we receive:

$2(0)-3y=9\\0-3y=9\\-3y=9\\y=\frac{9}{-3} \\y=-3$

Therefore, the point is (0,-3).

HELP DUE IN 5 MINUTES

Daniel [21]

$\huge \mathfrak \blue{Solution \: - }$

The formula for area of triangle is -

$\frac{1}{2} \times base \times height$

________________________________

So, the area of first triangle =

$\frac{1}{2} \times base \: \times height$

$\frac{1}{2} \times 4 \times 3$

$= \pink{6 \: units}$

________________________________

Area of second triangle =

$\frac{1}{2 } \times base \times height$

$\frac{1}{2} \times 4 \times 6$

$= \pink {12 \: units}$

________________________________

Area of second triangle - Area of first triangle

$= 12 - 6$

$= 6$

$\sf \underline\purple{The \: area \: increases \: by \: 6 \: square \: units.}$

Isabell is thinking of a even number between 234 and 250 the sum of the digits is double the digit in the ones place what is Isa

Lelu [443]

Answer:

246.

Step-by-step explanation:

Let the number be 2xy, then

2 + x + y = 2y and y must be even because the whole number is even.

y = 2 + x .

Now x must be even because y is even.

The only 2 numbers which fit are x = 4 and y = 6 so the number is 246.

Checking: 2+4+6 = 12 and 12 = 2*6.

Can somebody help me with these to questions how do you find the area of the circle

Grace [21]

13)

Circumference (C) = 2π·r

11π = 2π·r

11/2 = r

******************************

Area (A) = π·r²

= π·(11/2)²

= 121π/4

≈ 94.985 in²

14)

diameter = 2r

42 = 2r

21 = r

*******************

Area (A) = π·r²

= π·(21)²

= 441π

≈ 1384.74 in²

***************************

$280/1384.74 in²

x = $0.20

Answer: about 20 cents per square inch
