what is the value of y in the triangle
Answer:
y ≈ 6.7
Step-by-step explanation:
Using the sine ratio in the right triangle
sin26.5° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{y}{15}[/tex] ( multiply both sides by 15 )
15 × sin26.5° = y , then
y ≈ 6.7 ( to 1 dec. place )
I NEED HELPP PLS!!!!!!!!!!!!!!!!!!!
Answer:
270
Step-by-step explanation:
The formula for finding the area of a triangle is base · height ÷ 2, or [tex]\frac{bh}{2}[/tex]
After plugging in the numbers given to the formula, we find that the area of the triangle is 27.
Then to account for the length, we multiply the area of the triangle by 10.
This gets us to 270.

Marcie heated a beaker of water in science class. The scatter plot shows the temperature (y), in degrees Celsius, of the water based on the number of minutes (x) she heated the water.
Part A: The line of best fit for this data is
y = 5.3x + 23. Use this equation to make a conjecture about the temperature of the water in the beaker if heated for 6 minutes.
A.
The water will be about 71⁰C.
B.
The water will be about 55⁰C.
C.
The water will be about 32⁰C.
D.
The water will be about 50⁰C.
Part B: What is the y-intercept in the line of best fit? What does the y-intercept represent in the scatter plot?
A.
5.3; the amount the temperature increases each minute
B.
5.3; the temperature of the water before it is heated
C.
23; the amount the temperature increases each minute
D.
23; the temperature of the water before it is heated
Answer:
Part AGiven function
y = 5.3x + 23The value of y at x = 6:
y = 5.3*6 + 23 = 54.8° CThe closest choice is :
B. The water will be about 55⁰CPart BThe y-intercept is the value of y when x = 0
y = 5.3*0 + 23 = 23° CThis is the initial temperature at zero minute time, before heating is applied.
Correct choice is:
D. 23; the temperature of the water before it is heatedA toy train set has a circular track piece. The inner radius of the piece is 6 cm. One sector of the track has an arc length of 33 cm on the inside and 55 cm on the outside. What is the width of the track?

Draw BC that divides ABD
into two smaller angles.
Measure each angle. Solve
this problem any way you
choose.
Answer:
Attached below is the missing figure
answer : ∠ABD = ∠AbC + ∠ CbD
Step-by-step explanation:
when Line BC is drawn to divide ∠ABD equally
solving each angle :
∠ABD > ∠AbC also angle
∠ABD > ∠ CbD
∴ ∠ABD = ∠AbC + ∠ CbD
assuming ∠B = 60°
therefore ∠b = 60 / 30 = 30°

Given cot A = 5/6 and that angle A is in Quadrant I, find the exact value of csc A in
simplest radical form using a rational denominator.
The trigonometric function gives the ratio of different sides of a right-angle triangle. The value of Cosec A is (√61)/(6).
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
The Cot is the ratio of the base of the triangle to the perpendicular side of the triangle, therefore, we can write,
Cot A = Base/Perpendicular = 5/6
Thus, the base of the triangle is 5 units, while the length of the perpendicular of the triangle is 6 units. Now the length of the hypotenuse side of the triangle is,
H² = 5² + 6²
H² = 25 + 36
H = √61
Now, the value of Cosec A can be written as,
Cosec A = Hypotenuse/Perpendicular = (√61) / (6)
Hence, the value of Cosec A is (√61)/(6).

What is the solution of 3x + y = 9 and 3x - 5y = 15?
Answer:
(10/3, -1)
Step-by-step explanation:
So there are two different ways.
First you could address for y and fitting it into the number cruncher. one condition for y1 and another for y2. At that point go second follow and press 5 and afterward press enter multiple times to discover the convergence.
the subsequent path is to tackle by hand. I would recommend address the primary condition for y and attachment the condition tackled for y into the other condition. so y = - 3x + 9 and 3x-5y=15. At that point you could do 3x - 5(- 3x+9) = 15. At long last address for x and plug in x into the two conditions to check whether you get a similar y esteem.
The appropriate response ought to be (10/3, - 1)
Answer:
x = 3 1/3, x = -1.
Step-by-step explanation:
3x + y = 9
3x - 5y = 15
Subtract second equation from the first to eliminate the 3x :
3x - 3x + y - (-5y) = 9 - 15
6y = -6
y = -1.
Plug y = -1 in first equation:
3x + -1 = 9
3x = 10
x = 10/3 = 3 1/3.

Aubree invested $27,000 in an account paying an interest rate of 0.0825% compounded monthly. Addison invested $27,000 in an account paying an interest rate of 0.08625 % compounded continuously. After 20 years, how much more money would Addison have in her account than Aubree, to the nearest dollar?
Answer:
A = $27,445.50
Step-by-step explanation:
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 0.0825%/100 = 0.000825 per year.
Solving our equation:
A = 27000(1 + (0.000825 × 20)) = 27445.5
A = $27,445.50
The total amount accrued, principal plus interest, from simple interest on a principal of $27,000.00 at a rate of 0.0825% per year for 20 years is $27,445.50.

Answer:
[tex]x\approx 7.0[/tex]
Step-by-step explanation:
Since we are given a right triangle, we can use right trigonometric ratios.
x is the opposite side to our angle. 10 is the adjacent side to it. Thus, we can use the tangent ratio:
[tex]\displaystyle \tan(\theta^\circ)=\frac{\text{opposite}}{\text{adjacent}}[/tex]
Substitute:
[tex]\displaystyle \tan(35^\circ)=\frac{x}{10}[/tex]
Solve for x:
[tex]x=10\tan(35^\circ)[/tex]
Use a calculator:
[tex]x=7.0020...\approx 7.0[/tex]
x=7 yards
Answer:
Solution Given:
Opposite = x
base=10yards
and angle is 35°
we know that
relationship between opposite and base is given by Tan angle
so
Tan 35°= opposite/base
Tan 35°*10=x
x= 7.002
x≈7 yards
