Answer:
I'm going to assume that you meant y=3x-8 and y=-4
This means that you would substitute -4 into the spot of y which gives you -4=3x-8. Once solved you would receive x=4/3.
Hope I helped have a nice day :)

A right cone has a slant height of 7 and a radius of 5. What is its surface
area?
O A. 357 units
B. 120 x units2
O c. 25x units2
D. 60 units
Answer:
D
Step-by-step explanation:
D. 60 Units
The surface area of the right cone is,
⇒ SA = 60π units²
What is mean by Multiplication?The multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
Radius of cone (r) = 5 units
Slant height of cone (l) = 7 units
Now, We know that;
The formula that is used to calculate the surface area of a cone is;
⇒ SA = πrl + πr²
Hence, We can substitute all the values we get;
⇒ SA = πrl + πr²
⇒ SA = π × 5 × 7 + π × (5)²
⇒ SA = 35π + 25π
⇒ SA = 60π units²
Thus, The surface area of the right cone is,
⇒ SA = 60π units²

Probability of picking 2 marbles without looking out of a bag containing 2 red marbles, 2 blue marbles, and 2 white marbles. What is the probability that you will choose a red marble and then a blue marble without replacing the red one?
Answer: 2/15
Step-by-step explanation:
2 red
2 blue
2 white
6 total
2/6 chance of getting red (1/3)
2/5 chance of getting blue next
2/5*1/3 = 2/15

The diameter of a circle is 6 in. Find its area to the nearest tenth.
Answer and Step-by-step explanation:
The area formula for a Circle is:
A = [tex]\pi r^2[/tex]
Diameter is equal to the radius times 2.
So, divide the diameter to get the radius.
6 divided by 2 equals 3.
Now, plug it into the formula.
[tex]A = \pi (3)^{2}[/tex]
A = [tex]9\pi[/tex]
Plug this into your calculator by multiplying 9 by pi.
We get the answer to be 28.3 when rounded to the nearest tenth.

Find the value of X and Y. Brainliest if you show work. Please and thank you
Answer:
x = 18, y = 7Step-by-step explanation:
Given is the cyclic quadrilateral.
Opposite angles of cyclic quadrilateral are supplementary:
m∠U + m∠W = 18014 + 4x + 6x - 14 = 18010x = 180x = 18m∠V + m∠T = 18015y - 4 + 12y - 5 = 18027y = 189y = 189/27y = 7U and w are opposing so supplementary
14+4x+6x-14=18010x=180x=18Same efor V and T
15y-4+12y-5=18027y-9=18027y=189y=7Find the value of YZ
Answer:
YZ = 44
Step-by-step explanation:
Let the intersection of XW and YZ equal A. For this problem, we can use power of a point in the scenario where two secants intersect in the interior of a circle. We get the equation:
WA * AX = ZA * AY
We can substitute the values we are given to get:
(2x - 6)(21) = (x + 1)(30)
42x - 126 = 30x + 30
12x - 126 = 30
12x = 156
x = 13
Using segment addition postulate, we can say that:
YZ = YA + AZ
And we can plug in what we know from the diagram:
YZ = 30 + x + 1
We can also plug in the value of x, 13
YZ = 30 + 13 + 1 = 44

Answer: x=43, y=180
Step-by-step explanation: x is 43 because the 43 next to it has the same value. y is 180 because the angle is a straight line.
To find the distance across the river, the given diagram is laid out. what is the distance rounded to the nearest meter?
Given:
Angle A = 18.6°
Angle B = 93°
Length of side AB = 646 meters
To find:
the distance across the river, distance between BC
Steps:
Since we know the measure of 2 angles of a triangle we can find the measure of the third angle.
18.6° + 93° + ∠C = 180°
111.6° + ∠C = 180°
∠C = 180° - 111.6°
∠C = 68.4°
Therefore the measure of angle C is 68.4°.
now we can use the law of Sines,
[tex]\frac{BC}{sinA}=\frac{AB}{SinC}[/tex]
[tex]\frac{BC}{sin(18.6)}= \frac{646}{sin(68.4)}[/tex]
[tex]BC[sin(68.4)] = 646 [sin(18.6)][/tex]
[tex]BC = \frac{646*sin(18.6)}{sin(68.4)}[/tex]
[tex]BC = \frac{646 * 0.3190}{0.9298}[/tex]
[tex]BC = 221.63[/tex]
[tex]BC = 222[/tex] meters
Therefore, the distance across the river is 222 meters.

________ probability is based on a uniform probability. Ask yourself: What SHOULD happen when you conduct an experiment?
A) Simple
B) Theoretical
C) Experimental
_____ probability is based on relative frequency. Ask yourself: What ACTUALLY occurred during such an experiment?
A) Simple
B) Theoretical
C) Experimental
HELPP!!!!
Answer:
The answer is "Experimental Probability ".
Step-by-step explanation:
The probability of experiments is uncertainty which is calculated several times as per the outcome of even an experiment. The probability distribution is probably dependent upon reasoning. This probability is a price of about one or zero. It was based on the relative frequency or what occurs during a probability test.

In a state assembly, 35% of the legislators are Democrats, and the other 65% are Republicans. 70% of the Democrats favor raising sales tax, while only 40% of the Republicans favor the increase. If a legislator is selected at random from this group, what is the probability that they favor raising sales tax? Give your answer as a percentage rounded to the nearest tenth.
Answer:
Probability of selecting a legislator who favors rising sales tax is 0.63
Step-by-step explanation:
Given
Percentage of legislators that are democrats = 0.35
Percentage of legislators that are Republicans = 0.70
All the democrats favor raise in sales tax , so their probability is 1
and only 40% of the Republicans favor raise in sales tax.
Probability of selecting a legislator who favors rising sales tax is
(0.35*1)+(0.70*0.40)
= 0.63
