Answer:
1/2, 3/10
1/21, 8/27
Step-by-step explanation:
Fractions are multiplied by multiplying the numerators and expressing that product over the product of the denominators:
[tex]\dfrac{a}{b}\times\dfrac{c}{d}=\dfrac{ac}{bd}[/tex]
In several cases here, the numerator product has factors in common with the denominator product. Those can be cancelled, reducing the product fraction to lowest terms.
[tex]\dfrac{3}{4}\times\dfrac{2}{3}=\dfrac{3\cdot2}{4\cdot3}=\dfrac{3\cdot2}{3\cdot2\cdot2}=\boxed{\dfrac{1}{2}}\\\\\dfrac{4}{5}\times\dfrac{3}{8}=\dfrac{4\cdot3}{5\cdot8}=\dfrac{4\cdot3}{4\cdot2\cdot5}=\boxed{\dfrac{3}{10}}\\\\\dfrac{1}{6}\times\dfrac{2}{7}=\dfrac{1\cdot2}{6\cdot7}=\dfrac{2}{2\cdot3\cdot7}=\boxed{\dfrac{1}{21}}\\\\\dfrac{4}{9}\times\dfrac{2}{3}=\dfrac{4\cdot2}{9\cdot3}=\boxed{\dfrac{8}{27}}[/tex]

Danielle earns $36.80 for 4 hours of yardwork. MacKenzie earns $50.40 for 6 hours of yardwork.Who earns more money per hour? How much more?
Answers
Answer:
Danielle earns $1.20 more than Mackenzie (per hour)
Step-by-step explanation:
To find out how much money per hour each person earns, you would divide the earinings by the number of hours;
Danielle: $36.80/4 = $9.20 per hour
MackKenzie: $50.40/6 = $8.40 per hour
To find out how much extra Danielle earns, you would subtract 8.40 from 9.20;
9.40 - 8.20 = $1.20
Thus, Danielle earns $1.20 more than Mackenzie per hour.

What is the area trapezoid ABCD A(-1,5) B(3,2) C(0,-2) D(-13,-11)
Answers
Answer:
62.5
Step-by-step explanation:
slope of AB = (5-2)/(-1 - 3) = -3/4
slope of BC = (2 - -2)/(3-0) = 4/3
AB ⊥ BC (slope -3/4 vs 4/3)
seg AB = √(-1 - 3)² + (5 - 2)² = √25 = 5
seg BC = √(3 - 0)² + (2 - -2)² = √25 = 5
seg AD = √(-1 - -13)² + (5 - -11)² = √400 = 20
Area (BC + AD) * AB / 2 = (5 + 20) * 5 / 2 = 62.5

ALGEBRA 1 QUESTION
Ingrid hit a golf ball. The height of the ball (in meters above the ground) t seconds after being hit is modeled by
h(t)=-5t^2+30t
1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation.
2) How many seconds after being hit does the ball reach its highest point?
__________seconds
Answers
Answer:
[tex]\huge\boxed{\text{1. } h(t) = -5(t-3)^2 + 45}[/tex]
[tex]\huge\boxed{\text{2. 3 seconds}}[/tex]
Step-by-step explanation:
If we're looking for the point at with the ball reaches its highest point, we want to find the graph's vertex. In order to get the equation into a form with the vertex in it, we need to convert the equation into vertex form. This is an equation in the form [tex]y=a(x-h)^2 + k[/tex], h being the x value of the vertex, and k being the y value of the vertex.
In order to convert our equation, [tex]-5t^2+30t[/tex] into vertex form, we can algebraically manipulate it to get it into the form we want.
[tex]-5t^2 +30t[/tex] [tex]-5 \cdot t^2 + 30t[/tex] (Separate the -5 from the t^2)[tex]-5(t^2-6t+0)[/tex] (Factor out a -5)[tex]-5(t^2 -6t + (-3)^2 - (-3)^2 + 0)[/tex] (Completing the Square)[tex]-5((t-3)^2 - (-3)^2 + 0)[/tex] (Binomial Formula)[tex]-5((t-3)^2 - 9)[/tex] (Simplify)[tex]-5(t-3)^2 + 45[/tex] (Factor the -5 back in)Therefore, our equation with the vertex in it is [tex]-5(t-3)^2 + 45[/tex]. To find the vertex, we can examine the equation to find the values of h and k in the formula [tex]y=a(x-h)^2 + k[/tex] (where the vertex coordinates are (h, k)).
It seems that h is 3 and k is 45. Therefore, the coordinate of the vertex is (3, 45). Since it asks for how many seconds after being hit does the ball reach its highest point, we would take the x value since x represents seconds. This is 3. Therefore, the ball reaches its highest point after 3 seconds.

Solve the following A/5+3=8
Answers
Answer:
Your answer is going to be a=1
Step-by-step explanation:
First things first, we want all the letters on the left side and all the numbers on the right side. So, you have to get rid of the three. In order to get rid of the three you have to take it away, so A/5=8-3. Then it will become A/5=5. After that you want to have A all by itself so divide it by 5, A/5=5/5. Then it will become A=1. Hope this helps! :)

To find:
The value of x.
Solution:
We have,
[tex]5^x=55[/tex]
Taking log both sides, we get
[tex]\log (5^x)=\log (55)[/tex]
[tex]x\log (5)=\log (55)[/tex] [tex][\because \log x^n=n\log x][/tex]
[tex]x=\dfrac{\log (55)}{\log (5)}[/tex]
Using the log values, we get
[tex]x=\dfrac{1.740}{0.699}[/tex]
[tex]x=2.48927[/tex]
[tex]x\approx 2.49[/tex]

In a basketball game Jamarcus made 15 out of 25 shots and tyrell made 32 out of 50 shots who’s the better shooter
Answers
Answer:
Jamarcus is the better shooter
Step-by-step explanation:
Jamarcus is better because he needs 10 more shots to reach 25 while tyrell needs 18 More shots to make 50
Answer:
Tyrell
Step-by-step explanation
Well this is simple you take Jamarcus shots made and divide it into the total shots which is 15/25=0.6 or 60%. So Jamarcus made 60% of the shots attempted. Tyrell made 32 out of 50 shots so that will be 32/50=0.64 or 64%. Since 64%>60% Tyrell is the better shooter
