Answer:
58%
Step-by-step explanation:
P(8) = 1/13
P (Heart of Diamond) = 1/2
add them together with a common denominator of 26 to get:
2/26 + 13/26 = 15/26 which is about 58%

What is the length of AC?
Answer:
10 + 20 = 30
Step-by-step explanation:
If you subtract 5 from 25 you get 20 which is the length distance from b to c. Let's do the same to 15, 15 - 5 = 10. So now let's add our given lengths: 10 + 20 = 30.

Sheila threw the discus 24 meters, which was 0.38 meter farther than Tiesha threw the discus. How far, in meters, did Tiesha throw the discus?
Answer:
23.62 meters
Step-by-step explanation:
Find how far Tiesha threw the discus by subtracting 0.38 from 24:
24 - 0.38
= 23.62
So, Tiesha threw the discus 23.62 meters
A triangle has vertices of (−3, 3), (−3, 2), and (1, −2). What are the coordinates after dilating from the origin by a scale factor of 1 2 ?
Answer:
(-1.5, 1.5), '(-1.5, 1) and (0.5, -1)
Step-by-step explanation:
Given the coordinate (x, y) If dilated by a factor k, the resulting coordinate will be (kx, ky).
Similarly given the coordinates of a triangle (−3, 3), (−3, 2), and (1, −2)
when dilated by a factor of 1/2, the new coordinates will be at;
A (-3, 3) = A'(1/2*-3, 1/2 * 3) = A'(-1.5, 1.5)
B (-3, 2) = B'(1/2*-3, 1/2 * 2) = B'(-1.5, 1)
C (1, -2) = C'(1/2*1, 1/2 * -2) = C'(0.5, -1)
There are 5,000 trout in a lake, the population decreases 2% yearly. How many trout will there be after 4 years?
Answer:
4,600
Step-by-step explanation:
First you find 2% of 5,000 which is 100 then you determine 2% every 4 years which is 100x4 which equals 400. then subtract 400 from 5,000 which gets you 4,600
Answer:
4600
Step-by-step explanation:
2% of 5000 is 100
100 x 4 = 400
5000 - 400 = 4600

Annie earns $320 for 8 hours of work. At that rate, how long would she have to
work to earn $1,120?
Answer:
28 hrs
Step-by-step explanation:
in 8 hrs she earns $320,
so in 1 hr she earns $320/8=$40
no. of hrs she takes to earn $1120 is,
=1120/40= 28 hrs
Annie would need to work 28 hours to earn $1,120 at the same rate.
To determine how long Annie would have to work to earn $1,120 at the same rate, we can set up a proportion based on the given information.
Let's define:
x = the number of hours Annie needs to work to earn $1,120.
According to the information given, Annie earns $320 for 8 hours of work. This can be expressed as the rate: $320/8 hours.
We can set up the proportion as follows:
320/8 = 1120/x
To solve this proportion, we can cross-multiply and then solve for x:
320x = 8 * 1120
320x = 8960
Dividing both sides of the equation by 320:
x = 8960/320
x = 28
Therefore, Annie would need to work 28 hours to earn $1,120 at the same rate.

Describe and correct the error a student made when writing the quadratic function f(x)=2(x+3)^2-4 in standard form
The student did not
A. Compute 9-4 correctly
B. Compute (x+3)^2 correctly
C. Distribute 2 to all necessary terms
The function in standard form is f(x)=
Answer:
y = 2x^2 + 12x + 14
Step-by-step explanation:
Write this equation in standard form. Start by performing the exponentiation:
y = 2(x^2 + 6x + 9) - 4
Perform the indicated multiplication:
y = 2x^2 + 12x + 18 - 4, or
y = 2x^2 + 12x + 14: This is the quadratic function in standard form.
The value of the quadratic function in standard form is,
⇒ f (x) = 2x² + 12x + 14
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The function is,
⇒ f (x) = 2 (x + 3)² - 4
Now, We get;
The value of the quadratic function in standard form is,
⇒ f (x) = 2 (x + 3)² - 4
⇒ f (x) = 2 (x² + 9 + 6x) - 4
⇒ f (x) = 2x² + 18 + 12x - 4
⇒ f (x) = 2x² + 12x + 14
Thus, The value of the quadratic function in standard form is,
⇒ f (x) = 2x² + 12x + 14

the cosine rule calculate tha angle of r 7.2 3,7 5.2
Given:
Consider the below figure attached with this question.
To find:
The measure of angle r by using the cosine rule.
Solution:
According to Law of Cosine,
[tex]a^2=b^2+c^2-2bc\cos A[/tex]
Using the Law of Cosine, we get
[tex](7.2)^2=(3.7)^2+(5.2)^2-2(3.7)(5.2)\cos r[/tex]
[tex]51.84=13.69+27.04-38.48\cos r[/tex]
[tex]51.84=40.73-38.48\cos r[/tex]
[tex]51.84-40.73=-38.48\cos r[/tex]
On further simplification, we get
[tex]11.11=-38.48\cos r[/tex]
[tex]\dfrac{11.11}{-38.48}=\cos r[/tex]
[tex]-0.2887=\cos r[/tex]
[tex]\cos^{-1}(-0.2887)=r[/tex]
[tex]106.780143=r[/tex]
[tex]r\approx 106.78[/tex]
Therefore, the measure of angle r is 106.78 degrees.

Three yrs hence, a men will be three time his brother age and the sum of present age is 18 find their present age
Answer:
Step-by-step explanation:
Let the age of a man = x
Age of his brother = y
Three yrs hence, a man will be three time his brother age
This is written as:
x + 3 = 3(y + 3)
x + 3 = 3y + 9 .... Equation 1
The sum of present age is 18
= x + y = 18
x = 18 - y
We substitute 18 - y for x in Equation 1
find their present age
18 - y + 3 = 3y + 9
Collect like terms
21 - 9 = 3y + y
12 = 4y
y = 12/4
y = 3 years
x = 18 - y
x = 18 - 3
x = 15 years
