Answer:
89 degrees
Step-by-step explanation:
Since these angles make up a triangle, we know that the total of these angles will make 180 degrees. So, we need to set the equations up appropriately, and solve for x:
[tex]180=(4x+1)+(2x-6)+(6x-7)\\180=12x-12\\192=12x\\x=16\\[/tex]
Then, you plug 16 back into the equation for angle J, and simplify:
[tex](6(16)-7)\\(96-7)\\(89)[/tex]
Therefore, the answer is 89 degrees.
Find the lateral area of the following
cone. Leave your answer in terms of .
12 cm
5 cm
LA = [ ? ]7 cm2
The lateral surface area of the cone will be 65π square cm.
What is the lateral surface area of a cone?Let d be the diameter of the base circle, l be the slant height, and h be the height of the cone.
Then the lateral surface area of the cone will be
LSA = πrl
Then the slant height is given as
l² = r² + h²
l² = 5² + 12²
l² = 25 + 144
l² = 169
l = 13 cm
Then the lateral surface area will be
LSA = π × 5 × 13
LSA = 65π cm²

Camden needs to lease out a music studio to record his new album. The studio charges an initial studio-use fee plus an hourly fee for each hour in the studio. The studio charges $50 per hour of use and the total cost charged for 5 hours is $700. Write an equation for the function P ( t ) , P(t), representing the amount of money Camden would have to pay to use the studio for t t hours.
Answer: [tex]P(t)=450+50t[/tex]
Step-by-step explanation:
Given
Studio charge $50 per hour and fixed charge for initial use
For 5 hours, it charges $700
Suppose x is the fixed charge
[tex]\therefore 700=x+50\times 5\\\Rightarrow x=700-250\\\Rightarrow x=\$450[/tex]
For t hours, studio charges
[tex]\Rightarrow P(t)=450+50t[/tex]

Subtract (5u + 6v) from (8u + 10v)
Answer:
-3u-4v
Step-by-step explanation:
5u+6v-(8u+10v)
=5u+6v+-1(8u+10v)
=5u+6v+-1(8u)+-1(10v)
=5u+6v+-8u+-10v
(combine like terms)
=5u+6v+-8u+-10v
=(5u+-8u)+(6v+-10v)
=-3u-4v

The value of the subtraction will be equal to -3u-4v.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the two expressions are (5u + 6v) and (8u + 10v). The subtraction will be calculated as,
5u+6v-(8u+10v)
S =5u+6v+-1(8u+10v)
S =5u+6v+-1(8u)+-1(10v)
S =5u+6v+-8u+-10v
(combine like terms)
S =5u+6v+-8u+-10v
S =(5u+-8u)+(6v+-10v)
S =-3u-4v
Therefore, the value of the subtraction will be equal to -3u-4v.

1.(x-1)^2 + y^2=9
2.x^2+(y+4)^2=9
3. (x-1) +( y - 4)^2=3

C.3
D.4
E.5
Answer:
[tex]\boxed {\boxed {\sf B. \ 2: x^2+(y+4)^2=9}}}[/tex]
Step-by-step explanation:
The equation for a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center and r is the radius.
We know that the center of the circle is (0, -4) and the radius is 3. Therefore:
h= 0 y= -4 r=3Substitute the values into the formula.
[tex](x-0)^2+(y--4)^2=(3)^2[/tex]
Solve the first parentheses.
(x-0)² = (x)²= x²[tex]x^2+(y--4)^2=(3)^2[/tex]
Solve the next parentheses.
(y--4)² = (y+4)²[tex]x^2+(y+4)^2=(3)^2[/tex]
Solve the exponent.
(3)²= 3*3=9[tex]x^2+(y+4)^2=9[/tex]
This is the finished equation, which corresponds with number 2. Choice B (2): x²+(y+4)²= 9 is correct.

A teacher would like to estimate the mean number of steps students take during the school day. To do so, she selects a random sample of 50 students and gives each one a pedometer at the beginning of the school day. They wear the pedometers all day and then return them to her at the end of the school day. From this, she computes the 98% confidence interval for the true mean number of steps students take during the school day to be 8,500 to 10,200. If the teacher had used a 90% confidence interval rather than a 98% confidence interval, what would happen to the width of the interval
Answer:
The answer is "It would decrease, but not necessarily by 8%".
Step-by-step explanation:
They know that width of the confidence level is proportional to a confidence level. As just a result, reducing the confidence level decreases the width of a normal distribution, but not with the amount of variance in the confidence level. As just a result, when a person teaches a 90% standard deviation rather than a 98 percent normal distribution, the width of the duration narrows.

Someone help me out with this my grade are bad
Answer:
2 units tall by 1 unit wide
Step-by-step explanation:
On the given rectangle it tell you the conversion to m is 1 unit = 2 m.
The new figure that needs to be drawn has a conversion of 1 unit = 8m.
So, the fist thing we need to do is calculate the m on the width at the height of the original, which is 16 by 8.
looking at this we can now convert this measurement into our new conversion of 1 unit = 8 m. We can do this by dividing the height and width separately.
Ex:
Since 16 is divided by 8 two times so that gives us the answer of 2 units.
8 is divisible by 8 one time so that gives us the width of 1 unit
if this is confusing just think of it like: x=[tex]\frac{16}{8}[/tex] for the height or x = [tex]\frac{8}{8}[/tex] for the width.
