First, Diana scores 12 points in total with three arrows. On her second turn, she scores 15 points. How many points does she score on her third turn?
Answer:
Third turn point = 21 points
Step-by-step explanation:
Given:
First turn point = 12
Second turn point = 15
Find;
Third turn point
Computation:
First turn point = 12
Assume;
Point for outer circle = a
Point for inner circle = b
So,
3a = 12
Point for outer circle = 4 point
Second turn point = 15
So,
2a + b = 15
2(4) + b = 15
Point for inner circle = 7
Third turn point = 3 x 7
Third turn point = 21 points

Fill in the blank. In the triangle below, x=__. Round your answer to two decimal places.
Given:
The figure of a right triangle.
To find:
The value of x.
Solution:
In a right triangle,
[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]
In the given right angle triangle,
[tex]\tan 52^\circ=\dfrac{x}{35}[/tex]
[tex]1.2799\times 35=x[/tex]
[tex]44.7965=x[/tex]
Approximate the value to two decimal places.
[tex]x\approx 44.80[/tex]
Therefore, the value of x is about 44.80 units.

What is the approximate measure of the leg opposite of angle A???
Answer:
8.7 cm
Step-by-step explanation:
take 60 degree as reference angle
using sin rule
sin 60=opposite/hypotenuse
[tex]\frac{\sqrt{3} }{2}[/tex]=opposite/10
[tex]\frac{\sqrt{3} }{2} * 10[/tex]=opposite
[tex]\sqrt{3} *5[/tex] = opposite
[tex]5\sqrt{3}[/tex] =opposite
8.66=opposite
8.7 =opposite

Ciara is naking a new outfit she needs 2 1/2 yards of the fabric for the shawl and 1 3/4 yards of fabric for the dress. If she has 3 yards of fabric,how much more does she needs?If the dance outfit is charged at $16 per yard how much will the dance outfit cost
Answer:
1 1/4 yards
$20
Step-by-step explanation:
The amount of fabric more that she needs can be determined by subtracting the sum of the yards needed for the shawl and the dress from the fabric she has
sum of the yards needed for the shawl and the dress =
[tex]2\frac{1}{2} + 1\frac{3}{4}[/tex]
[tex]3\frac{2 + 3}{4}[/tex] = [tex]3\frac{5}{4}[/tex] = [tex]4\frac{1}{4}[/tex]
Yards needed
[tex]4\frac{1}{4} - 3[/tex] = [tex]1\frac{1}{4}[/tex]
cost of dance outfit = $16 x [tex]1\frac{1}{4}[/tex]
[tex]\frac{5}{4}[/tex] × $16 = $20

PLS ANSWER FAST 60 PTS
Answer:
72 sqrt(3) ft^2
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
We can find the height by
tan theta = opp /adj
tan 60 = h /12
12 tan 60 = h
12 sqrt(3) = h
Then we can find the area
A = 1/2 bh where b is the length of the base and h is the height
A = 1/2 ( 12) ( 12 sqrt(3))
A = 72 sqrt(3) ft^2

Which expression represents the total number of miles he biked? A. 5 × ( 3 + 2 + 2 1 4 ) 5 × ( 3 + 2 + 2 1 4 ) B. 5 + ( 3 × 2 × 2 1 4 ) 5 + ( 3 × 2 × 2 1 4 ) C. 5 × ( 3 × 2 × 2 1 4 ) 5 × ( 3 × 2 × 2 1 4 ) D. 5 + ( 3 + 2 + 2 1 4 )
Answer:
A. 5 × ( 3 + 2 + 2 1/4 )
Step-by-step explanation:
Hayden rode his bike 5 times. Each time, he biked a 3-mile path, a 2-mile path, and a 2 1/4 -mile path.
The expression represents the total number of miles he biked is calculated as:
The number of times he rode his bike × (sum of the number of miles he biked)
= 5 × ( 3 mile + 2 miles + 2 1/4 miles)
= 5 × (3 + 2 + 2 1/4)
Therefore, Option A is the correct option

The area of a circle is 4π ft². What is the circumference, in feet? Express your answer in terms of \piπ.
Answer:
C = 4 pi ft
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
Solving for r
4 pi = pi r^2
Dividing each side by pi
4 = r^2
Taking the square root of each side
sqrt(4) = sqrt(r^2)
2 = r
Now we can find the circumference
C = 2 * pi *r
C = 2*pi*2
C = 4 pi ft

If you apply the changes below to the cubic parent function, F(x)=x3, what is the equation of the new function if it reflects across the y-axis and vertically stretches by multiplying by 7
Answer:
g(x) = 7(-x)³
Step-by-step explanation:
The cubic parent function is given as; f(x) = x³
Now, we are told that it reflects across the y-axis. This means that the new function will take the form;
g(x) = f(-x)
Thus, the new function is;
g(x) = (-x)³
Now,we are told that this new function stretches by multiplying by 7. Thus, we now have;
g(x) = 7(-x)³

Calculate the length of AC, to the nearest tenth of a centimeter.
Answer:
AC ≈ 11.0 cm
Step-by-step explanation:
Using Pythagoras' identity in Δ CDE and Δ ADE
CE² + DE² = DC²
CE² + 7² = 8²
CE² + 49 = 64 ( subtract 49 from both sides )
CE² = 15 ( take the square root of both sides )
CE = [tex]\sqrt{15}[/tex]
-------------------------------------------------------
AE² + DE² = DA²
AE² + 7² = 10²
AE² + 49 = 100 ( subtract 49 from both sides )
AE² = 51 ( take the square root of both sides )
AE = [tex]\sqrt{51}[/tex]
Then
AC = AE + CE = [tex]\sqrt{15}[/tex] + [tex]\sqrt{51}[/tex] ≈ 11.0 cm ( to the nearest tenth )

Answer:
[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
[tex]-\frac{12}{16} + \frac{11}{12}[/tex]
take lcm of the denominator
lcm=48
[tex]\frac{-12*3 + 11*4}{48}[/tex]
[tex]\frac{-36 + 44}{48}[/tex]
[tex]\frac{8}{48}[/tex]
[tex]\frac{1}{6}[/tex]
Answer:
[tex]=\frac{1}{6}[/tex]
Step-by-step explanation:
[tex]-\frac{12}{16}+\frac{11}{12}[/tex]
the lcm of 16 and 12 is 48
[tex]-\frac{12}{16} =-\frac{36}{48}[/tex]
[tex]\frac{11}{12} =\frac{44}{48}[/tex]
[tex]-\frac{36}{48} +\frac{44}{48}=\frac{8}{48}[/tex]
[tex]=\frac{1}{6}[/tex]
