Answer:
Step-by-step explanation:
The figure is divided into a rectangle and a right-triangle.
The area of the figure is the sum of the individual areas of the rectangle and triangle
Area of rectangle = Length x Width = 10 ft x 8 ft = 80 ft²
Area of triangle = 1/2 x Base X Height = 1/2 x 6 ft x 8 ft =24ft²
Hence, the area of the figure is:
80 ft²+ 24ft² = 104 ft²
Answer:
104 ft^2
Step-by-step explanation:
The figure consist a rectangle and a triangle
to calculate triangle's area we multiply height and base then divide it by two
the height of the triangle is 8 ft (the given is a special right triangle)
8*6/2 = 24 ft^2
to calculate the area of the rectangle we multiply width and length
8*10 = 80 ft^2 the total area of the figure is :
24 + 80 = 104 ft^2

5 times some number added to 8 amounts to 10 added to the product of 3 and the number
How do you solve this
Answers

Answer:
the number is 1
Step-by-step explanation:
First of all, you need to know what you're solving. Here, we assume you're trying to find "the number."
__
Let n represent "some number." The given relation can be written using math symbols as ...
5n +8 = 10 +3n
Subtract 3n +8 from both sides to separate the variable and the constant terms.
2n = 2
n = 1 . . . . . . . divide by 2
The number is 1.

5 times 1, added to 8 is 13. This amounts to the same thing as 10 added to the product of 3 and 1.
Given log4(3) =0.7925 and log4(5) =1.1610, use log properties to find log4(300).
Answers
Answer:
4.1145
Step-by-step explanation:
You can use the following formula to solve this kind of problems,
[tex] log_{a}(b) + log_{a}(c) = log_{a}(bc) [/tex]
So, let's start of with log4_(300). Since the question have already gave log4_(3) =0.7925 and log4_(5) =1.1610. It means that you have to split the 300 into the simplest form where almost all of the numbers are 3 and 5.
[tex] log_{4}(300) = log_{4}(4 \times 5 \times 3 \times 5) \\ = log_{4}(4) + log_{4}(5) + log_{4}(3) + log_{4}(5) \\ = 1 + 1.1610 + 0.7925 + 1.1610 \\ = 4.1145[/tex]
x ^ 2 − 17x − 60
Which expression is equivalent to the expression above?
(Please explain in simple terms cause, it's usually hard for me to understand)
Answers
[tex] {x}^{2} - 17x - 60 \\ (x + 3)(x - 20)[/tex]
First we put parentheses and in each bracket we put (X) and then we put the signs x² is positive and the 17X before it is a negative q is positive with negative —> negative, and negative before 17X and negative before the 60 —> positive. And then the number that does not have (x) where did it come from, for example 60 came from 20 x 3 or 30 x 2...etc. We can verify this by multiplying the parentheses together and the same number comes out .
Or it can be checked by multiplying the first bracket 3 with x from the second parenthesis comes out 3X and negative 20 from the second parenthesis with X from the first parenthesis and subtract 3X from –20xcomes out –17X .

Sarah, Bob and Nellie are cousins. Sarah is half the age of Bob. In three years time Nellie will be twice as old as Sarah. Their ages at the moment add to 38 years. Determine the ages of Sarah, Bob and Nellie
Answers
9514 1404 393
Answer:
Sarah is 7Bob is 14Nellie is 17Step-by-step explanation:
Let s, b, n represent the current ages of Sarah, Bob, and Nellie, respectively.
s = b/2 . . . . . . Sarah is half Bob's age
2(s+3) = n+3 . . . . in 3 years, Nellie will be twice Sarah's age
s + b + n = 38 . . . . . their ages now add to 38
__
We can rearrange the first two equations to find Bob and Nellie's age in terms of Sarah's. Then we can substitute into the third equation to find Sarah's age.
b = 2s . . . . . . multiply the first equation by 2
2s +3 = n . . . . subtract 3 from the second equation and simplify
s +(2s) +(2s+3) = 38 . . . . substitute for b and n
5s = 35 . . . . . . . . . . . . subtract 3, collect terms
s = 7 . . . . . . . . . . . . divide by 5
b = 2(7) = 14
n = 2(7) +3 = 17
Sarah is 7, Bob is 14, and Nellie is 17.

Ruben is driving along a highway that passes through Barstow. His distance d, in miles, from Barstow is given by the equation
d = |210 − 60t|,
where t is the time, in hours, since the start of his trip and
0 ≤ t ≤ 5.
When will Ruben be exactly 90 miles from Barstow? (Enter your answers as a comma-separated list.)
Answers
The absolute value of a number returns the positive value of the given number. Ruben will be at exactly 90 miles in 2 hours or 5 hours
Given that:
[tex]d = |210 - 60t|[/tex]
To calculate t when [tex]d = 90[/tex], we have:
[tex]90 = |210 - 60t|[/tex]
Rewrite as:
[tex]|210 - 60t| = 90[/tex]
Remove absolute bracket
[tex]210 - 60t = 90 \ or\ 210 - 60t = -90[/tex]
Collect like terms
[tex]- 60t = -210 + 90 \ or\ - 60t = -210 -90[/tex]
[tex]- 60t = -120 \ or\ - 60t = -300[/tex]
Divide through by -60
[tex]t = 2 \ or\ t = 5[/tex]
Hence, Ruben will be at exactly 90 miles in 2 hours or 5 hours

Zhi and her friends moved on to the card tables at the casino. Zhi wanted to figure out the probability of drawing a face card or an Ace.
Choose the correct probability of drawing a face card or an Ace. Answer choices are in the form of a percentage, rounded to the nearest whole number.
31%
8%
4%
25%
Answers
Answer:
8%
Step-by-step explanation:
Ok, there is 52 cards per deck, 13 per suit ( club, diamond, heart, and spade)
if you multiply 13 by 4 ( 4 is dependent on the number of suit, and 4 will always be the number of suit )
The probability is 8%.
Why, because 25 would be pulling a random card and your saying you want the suit to be diamond the probability of you getting a random diamond card would be 25%. But were not doing that. So cross out 31% and 25%.
Also, 4% would be as your counting 100 cards. So that leaves me with 8%.

Consider the attachment. There, we have identified a point C that makes ABC a right triangle with the right angle at C.
The Pythagorean theorem gives you the relationship between side lengths of a right triangle. The square of the hypotenuse (longest side) is equal to the sum of the squares of the other two sides.
AB² = AC² +BC²
We can count grid squares to find the lengths of AC and BC. They are 2 units and 7 units, respectively. This means ...
AB² = 2² +7²
AB² = 2·2 +7·7 = 4 +49 = 53
When we know the square, we can find what it is the square of by taking the square root. Generally, a calculator is required for this.
AB = √53 ≈ 7.2801099
When we round this number to two decimal places (the nearest hundredth), we get ...
AB ≈ 7.28 . . . units
_____
Additional comments
You will notice that the length AC in the diagram is the difference of the x-coordinates of points A and B. Similarly, the length BC in the diagram is the difference of y-coordinates. Then the square AB² is the sum of the squares of these differences. The length AB is the square root of that sum.
In general, this is how you find the length of a line segment from its end point coordinates.
