Answer:
9.03 = x
Step-by-step explanation:
Since we have the Hypotenuse given and we need to find the value of the adjacent side of the given angle we would use the Cosine Ratio;
Cos(46) = [tex]\frac{x}{13}[/tex]
To solve for "x" we would first have to isolate the "x" all to itself.
To isolate the variable, simply multiply 13 to the both sides of "="
=> Cos(46) * 13 = x
=> 9.03 = x
So you can write the answer in either of the 2 ways mentioned above, if you need a fully simplified answer the second answer would be a better fit. If u just need the Equation the 1st equation would be the better fit.
Hope this helps!
Solve for x.
2x + 15
3x - 20
x = [?]
Answer:
x= 7
3x-20
2x+15
you would add 3x+2x equals 5x and 20 +15= 35
5x+35
35 divided by 5 is 7 and then on the 5x divide by 5 and leaves x=7
Answer:
35
Step-by-step explanation:
Angles 2x + 15 and 3x - 20 are adjacent angles.
Adjacent angles are equal.
3x - 20 = 2x + 15
3x - 2x = 15 + 20
x = 35
Line m is mapped onto line n by a dilation centered at the origin with a scale factor of 2. The equation of line m is 3x−2y=63x-2y=63x−2y=6 . Find the equation for line n showing all work for full credit.
9514 1404 393
Answer:
3x -2y = 12
Step-by-step explanation:
The constant in the standard form equation for a line is proportional to the distance of the line from the origin. Dilation by a factor of 2 moves the line to twice its original distance from the origin. The equation of the new line will have the constant 2×6 = 12:
3x -2y = 12
_____
Additional comment
The actual distance of line ax+by=c from the origin is ...
d = |c|/√(a²+b²)
The distance from any point in the plane to the line is ...
d = |ax +by -c|/√(a²+b²)
The previous equation is for the special case of (x, y) = (0, 0), the distance from the origin.
Felipe buys candy that costs $7 per pound. He will spend at least $56 on candy. What are the possible numbers of pounds he will buy?
Answer:
x ≥ 8
Step-by-step explanation:
Let x be the number of pounds he buys. As each pound costs 7 dollars and he must spend at least 56 dollars, we have:
7x ≥ 56
x ≥ 8 (divide each side by 7)
Thus, our answer is any number above 8.
There are 35 red marbles, 8 blue marbles, and 7 green marbles in a bag. What is the theoretical probability of randomly drawing a red marble?
○ 35%
○ 25%
○ 42.9%
○ 70%
Answer:
70%
Step-by-step explanation: 35/50 equals 0.7
Answer:
70%
Step-by-step explanation:
The total number of marbles will be 35 + 8 + 7 = 50 marbles in total (all the colors added together). The probability of drawing a red marble will be the number of red marbles divided by the total marbles. This also fits the probability formula of (desired outcomes)/(total number of outcomes. Thus, we have 35 red marbles and 50 marbles in total. So, we get 35/50, which is 70%.

Answer:
Relation 1: Not a function
Relation 2: Not a function
Relation 3: Function
Relation 4: Not a function
Step-by-step explanation:
Recall: a relation can only be a function if and only if each domain value has only 1 range value mapped to it or related to it. This means that a domain value can only have exactly one range value for the relation to be qualified a function.
✔️Relation 1 is NOT A FUNCTION.
Rationale: Two of the domain values (star and sky) is having more than 1 range value assigned to each.
✔️Relation 2 is NOT A FUNCTION:
Rationale: domain value, 9, has several range values assigned to it.
✔️Relation 3 is A FUNCTION:
Rationale: each domain value do not have more than one range values assigned to it.
✔️Relation 4 IS NOT A FUNCTION:
Rationale: the domain value, 6, has two range values, m and d, assigned to it.

Walmart offers a shirt initially at $100. Then one week later, Walmart offers the shirt at 15% off. The
shirt still doesn't sell, so after another week, Walmart reduces its new price by 20%. How much does the
shirt cost now?
Choose one. 5 points
$68.00
$65.00
$69.00
$60.00
Answer:
$65.00
Step-by-step explanation:
Cost price of shirt after giving discounts is equals to [tex]\$68[/tex].
What is Cost price?" Cost price is defined as the price to be paid at the time of purchase any product."
According to the question,
Initial cost price of shirt [tex]= \$100[/tex]
First discount [tex]= 15\%[/tex]
Discount amount [tex]= 15\%[/tex] of [tex]100[/tex]
[tex]= \frac{15}{100} \times 100\\\\= \$15[/tex]
Cost price after first discount [tex]= 100 - 15[/tex]
[tex]= \$85[/tex]
Second discount [tex]= 20\%[/tex]
Discount amount [tex]= 20\%[/tex] of [tex]85[/tex]
[tex]= \frac{20}{100} \times 85\\\\= \$17[/tex]
Cost price after first discount [tex]= 85 - 17[/tex]
[tex]= \$68[/tex]
Hence, cost price of shirt after giving discounts is equals to [tex]\$68[/tex].

Answer:
0.512 ; - 0.538
Step-by-step explanation:
Using the standard linear regression relation :
y = bx + c
b slope ; c = intercept ; y = dependent ; x = independent variable.
For finalist between 2004 - 2014 ;
y = 0.024x - 0.328
x = 35
y = 0.024(35) - 0.328
y = 0.512
For finalist between 1990 - 2014 ; with 14 winners ; change in daily circulation :
y = -0.015x - 0.328
x = 14.
y = -0.015(14) - 0.328
y = - 0.538
There are 10 bags of cereal in a pantry. Each serving of cereal is 1/8 of a bag.
How many servings of cereal are there in the bags in the pantry?
Answer:
80 servings
Step-by-step explanation:
there is 8 serving per bag
Answer:
80
Step-by-step explanation:
Let servings be s and the bag be b
s = 1/8 b
multiply both sides by 8
8s = b
For 10 bags, it will be 10*8s = 80s which is 80 servings.

Answer:
Landon's purchase: p +5g = 17.55Lesley's purchase: 4p +2g = 13.50pretzel: $1.80granola bar: $3.15Step-by-step explanation:
The equation representing either purchase will multiply the number of items by their cost, for each item, and show the total as the cost of the purchase. Here, p is defined as the cost of a pretzel; g is defined as the cost of a granola bar.
Landon's purchase
1 pretzel + 5 bars will cost 1p +5g
That cost is 17.55, so the equation is ...
p +5g = 17.55
Lesley's purchase
4 pretzels + 2 gars will cost 4p +2g
That cost is 13.50, so the equation is ...
4p +2g = 13.50
__
To solve, you can subtract the second equation from 4 times the first:
4(p +5g) -(4p +2g) = 4(17.55) -(13.50)
18g = 56.70 . . . . collect terms
g = 3.15 . . . . . . . . divide by 18
Then the cost of a pretzel can be found using the first equation.
p + 5(3.15) = 17.55
p = 1.80
The cost of a pretzel is $1.80; the cost of a granola bar is $3.15.
In certain regions of the country, elk can cause damage to agricultural crops by walking through the fields. One strategy designed to limit elk from crossing a field is to surround the field with a fence. Some elk, however, will still be able to bypass the fence. For a period of one month, the number of elk found crossing a sample of fields with a fence was recorded and used to construct the 95 percent confidence interval (2.9,4.4) for the mean number of elk. Assume that the conditions for inference were checked and verified.
Required:
The interval (2.9, 4.4) provides convincing statistical evidence which claims?
Answer:
The mean number of elk to cross all fields protected by fence is equal to 3.65 per month.
Step-by-step explanation:
Given the confidence interval : (2.9,4.4)
Confidence = xbar ± standard Error
To obtain the mean :
We first calculate the standard error :
Standard Error from confidence interval :
(Upper boundary - Lower boundary interval) / 2
(4.4 - 2.9) / 2
1.5 / 2
= 0.75
Hence, the mean can be obtained as :
(Lower boundary + 0.75) or (Upper boundary - 0.75)
Lower boundary + 0.75 = 2.9 + 0.75 = 3.65
Upper boundary - 0.75 = 4.4 - 0.75 = 3.65
Write at least three expressions that are equivalent to 3(2x - 5)
Answer:
6x - 15
6x - (5 · 3)
(3 · 2x) - 15
So, for #1, we can just simplify 3(2x - 5) to get another expression:
3(2x - 5),
6x-15
For the next one, we could make a new equation that equals 6x-15:
(3x)+(3x)+(5 *-3)
Then for the last one, how about rewrite it so all of the values are inversely negated?
3(2x - 5),
-3(-2x +5)
