Step 1: Identify Variables
Angle measure = 58°
Adjacent side of angle = x
Hypotenuse = 9
Step 2: Solve for x
Substitute [cosine]: cos58° = x/9Isolate x: 9cos58° = xEvaluate: 4.76927 = xRewrite: x = 4.76927Round: x ≈ 4.8Answer:

Write an equation of the line that passes through (1, 2) and is perpendicular to the line y=13x+4.
Answer:
Step-by-step explanation:
y=-1/13x since it is perpendicular flip it and make it negative
Answer:
y = -1/13x + 27/13
Step-by-step explanation:
A perpendicular line will have the opposite reciprocal and sign.
So the perpendicular line slope to y = 13x + 4 would be -1/13
NOW PLUG IN (1, 2) TO GET THE Y- INTERCEPT
2 = -1/13(1) + b (b represents the y- intercept)
2 = -1/13 + b (add 1/13 to both sides)
y = -1/13x + 27/13 is the perpendicular line.

solve this plz
z = 2a + 2. for a
Answer:
a=(z-2)/2
Step-by-step explanation:
You need to isolate your "a" variable so first you want to subtract 2 from both sides, leaving you with:
z-2=2a
then you want to divide by 2 on both sides to isolate your "a" variable which would leave you with
a=[tex]\frac{(z-2)}{2}[/tex]

Question 5
Trent has 12 cups of ice cream for his daughter's birthday party
If each serving is
3/4
of a cup, how many children can eat ice cream?
А
1
B
9
С
12
D
16
Answer:
B. 9
Step-by-step explanation:
12 times 3/4 is 9
Answer:
it takes 4 of the 3/4 servings to make a whole number and it's 3 cups.
12/3= 4 and 4*4= 16
so 16 children can eat ice cream
or you could do 12/0.75= 16
you would do that because 3/4=0.75
you would divide and not multiply because you're seeing how many times 0.75 can go into 12

is 4 7%. What will the total cost of the loan be for 10 years?
Answer:
57,585
Step-by-step explanation:
55,000.x4.7%=2585.
55000.+2585=57,585
Answer:
$57,337.50
Step-by-step explanation:
In order to get the answer we would have to add 55, 000 and 4 [tex]\frac{1}{4}[/tex]% of 55,000 (because of the interest rate). In order to find 4 [tex]\frac{1}{4}[/tex] % we would have to multiply 55, 000 by 0,0425. So now we get the following.
Total cost of the loan = 55,000 + 55,000 x 0.0425 = 55,000 + 2,337.5 =
57,337.5
What is the slope of a line that is perpendicular to the line whose equation is 8y−5x=11?
Ill give someone brainlist
9514 1404 393
Answer:
-8/5
Step-by-step explanation:
When you solve for y, the slope of the line is the x-coefficient. For the given line, that is ...
8y = 5x +11 . . . . . add 5x
y = 5/8x +11/8 . . . . divide by 8
The given line has a slope of 5/8. The perpendicular line will have a slope that is the opposite of the reciprocal of this:
-1/(5/8) = -8/5 . . . . slope of perpendicular line
Answer:
The slope of the perpendicular line will be -8/5, or -1.6
Step-by-step explanation:
First we need to rearrange the equation to show the slope, putting in the format y = sx + c:
[tex]8y - 5x = 11\\8y = 5x + 11\\y = \frac{5}{8}x + \frac{11}{8}[/tex]
So the given line has a slope of 5/8.
A line perpendicular to that will have a negative reciprocal of that slope, so it's slope will be -8/5.

A city has a vacant lot in the shape of an isosceles trapezoid and the city workers are installing a fence around the lot. What length of fencing is required? Round the answer to the nearest meter. А 25 m B x 25 m 45° The length of fencing required is meters.
Answer:
Length of the fence required = 135 m
Step-by-step explanation:
Total length of the fence required to cover the vacant lot = Perimeter of the isosceles trapezoid
Perimeter of ABCD = AB + BC + CD + AD
Since, AB = BC = EF = ED = 25 m
From the given right triangle BEC,
m∠EBC = m∠ECB = 45°
ΔBEC will be an isosceles triangle.
So, BE = EC
By Pythagoras theorem,
BC² = BE² + EC²
25² = 2(EC)²
EC = [tex]\frac{25}{\sqrt{2}} =17.7[/tex] m
And DC = (DF + EF + EC)
= EC + EF + EC [Since, DF = EC]
= 2EC + EF
= 35.4 + 25
= 60.4 m
Hence. perimeter of ABCD = 25 + 25 + 60.4 + 25
= 135.4 m
≈ 135 m
Therefore, length of the fence required = 132 m
Sydney has a bag of stuffed animals containing, 1 elephant, 4 bears, 3 cats, and 2 dogs. If she randomly selects 1 stuffed animal from the bag, places it on her bed and then selects another animal. What is the probability that she chooses a bear both times?
Answer:
2/15
Step-by-step explanation:
Step one:
given data
sample space
1 elephant,
4 bears,
3 cats, and
2 dogs.
sample size= 1+4+3+2= 10
Required:
By selecting without replacement, the probability that she chooses a bear both times
Step two:
the first event= Pr(bear)= 4/10= 2/5
the second event, the sample size is now 9 and the number of bears is now 3
Pr(bear)= 3/9= 1/3
Hence, the probability that she chooses a bear both times
= 2/5*1/3
=2/15

Answer:
the answer for this is B 9
Answer:
B
Step-by-step explanation:
Consecutive angles are supplementary, thus
30 + 5x + 15 + 10x = 180 , that is
15x + 45 = 180 ( subtract 45 from both sides )
15x = 135 ( divide both sides by 15 )
x = 9 → B
