Answer:
The speed of the pass that clocked is 30.31 yards per seconds
Step-by-step explanation:
Given as :
The speed of the pass = 62 miles per hour
Let The speed in yards per second = x yps
So, ∵ The speed = 62 miles per hour
Or, The speed = [tex]\dfrac{\textrm 62 miles}{\textrm 1 hour}[/tex]
or, The speed = [tex]\dfrac{\textrm 62 miles}{\textrm 3600 secons}[/tex]
∵ In 1 hour = 3600 seconds
So, The speed = 0.0172 miles per second
Now, Again
Since 1 mile = 1760 yards
So, 62 miles = 1760 × 62 = 109,120 yards
∴ The speed in yard per second = [tex]\dfrac{\textrm 109,120 yard}{\textrm 3600 seconds}[/tex]
I.e The speed in yards per second = 30.31 yards per seconds
Hence The speed of the pass that clocked is 30.31 yards per seconds Answer
In a video game green gems are worth 5 points and blue gems are worth 10 points. Eric collects 25 gems and earned 160?points form his gems. Find how many green gems and how many blue gems Eric collected.
Eric collected 18 green gems and 7 blue gems.
Step-by-step explanation:
Let,
Green gems = x
Blue gems = y
One green gem = 5 points
One blue gem = 10 points
According to given statement;
x+y=25 Eqn 1
5x+10y=160 Eqn 2
Multiplying Eqn 1 by 5;
[tex]5(x+y=25)\\5x+5y=125\ \ \ Eqn\ 3[/tex]
Subtracting Eqn 3 from Eqn 2;
[tex](5x+10y)-(5x-5y)=160-125\\5x+10y-5x-5y=35\\5y=35[/tex]
Dividing both sides by 5;
[tex]\frac{5y}{5}=\frac{35}{5}\\y=7[/tex]
Putting y=7 in Eqn 1;
[tex]x+7=25\\x=25-7\\x=18[/tex]
Eric collected 18 green gems and 7 blue gems.

Eric collected 18 green gems and 7 blue gems. This conclusion is reached by forming and solving a system of linear equations based on the problem's conditions related to the total number of gems and their respective point values.
Explanation:This question deals with a system of equations, defined by the value of the gems and the total number of gems. Here, let's represent green gems as 'g' and blue gems as 'b'.
The two equations formed from the problem are as follows: g + b = 25 (since Eric collected 25 gems) and 5g + 10b = 160 (since green gems are worth 5 points each and blue ones 10, yielding a total score of 160).
To solve it, we need to isolate one of the variables: first, multiply the first equation by 5: 5g + 5b = 125. Then subtract this equation from the second equation, so we get 5b = 35, which simplifies to b = 7.
Substitute b = 7 into the first equation to get g = 25 - 7 = 18. Therefore, Eric collected 18 green gems and 7 blue gems.

Answer: 66.5
Step-by-step explanation:
divide the figure into a triangle (the top part) and a rectangle (the lower part)
To find the area of the rectangle use the formula:
length times width = area
(LW=A)
8 times 7 is 56 so the area of the rectangle is 56.
the formula for area of a triangle is base times height halfed
(BH)1/2
the height is 3 because the height of the entire figure is 11 so subtract the height of the rectangle from that (8) to get 3.
the base is 7 so
7(3)(1/2) is 10.5
add up the two areas together (10.5+56) to get 66.5 cm squared.

represents yard. To buy a fence for the garden, she nee
to know its perimeter. What is the perimeter of the garde
od coction of the
Answer:
The perimeter of the garden is 14 yard.
Step-by-step explanation:
Consider the figure:
Each unit on the grid represents [tex]\frac{1}{2}[/tex] yard.
From the figure we can find that:
The length of FA is 3.5 yard
The length of EF is 3.5 yard
The length of DX is 2 yard
The length of CD is 2 yard
The length of CB is 1.5 yard
The length of AB is 1.5 yard
To find the perimeter of the garden we need to add all the length as shown:
Perimeter = FA + EF + DX + CD + CB + AB
Perimeter = 3.5 + 3.5 + 2 + 2 + 1.5 +1.5
Perimeter = 14 yards
Hence, the perimeter of the garden is 14 yard.

A) A
B) B
C) C
D) D
Answer:
Step-by-step explanation:
Wheres the picture?
The equation (5 x 2) + (5 x 4) = 5 x (2 + 4) showcases the distributive property in mathematics where two different expressions yield the same result.
The equation (5 x 2) + (5 x 4) = 5 x (2 + 4) is a demonstration of the distributive property in mathematics.
(5 x 2) + (5 x 4) can be simplified as 10 + 20 = 30.
5 x (2 + 4) can be simplified as 5 x 6 = 30.
Hence, both sides of the equation result in the same value, displaying the equality of the expression.

the difference between the measures of two supplementary is 42. Find both angles.
Answer:
111 deg and 69 deg
Step-by-step explanation:
let the angles be x and y
given:
x - y = 42 degrees -------> eq 1
also given that they are supplemantry,
i.e x + y = 180 degrees ----------> eq 2
by elimination,
eq 1 + eq 2
(x-y) + (x+ y) = 42 + 180
2x = 222
x = 111 degrees (substitute back into eq 2)
111 + y = 180
y = 180 - 111
y = 69 deg
