Answer:
0.5
Step-by-step explanation:
5+a•b, 2•3 is 6, +5 is 11.
4+6•b, 6•3 is 18, +4 is 22.
I'm using PEMDAS/GEMDAS, which means I did multiplication first.
I'm assuming the / means to divide, so 11/22 is 0.5
HELP ME PLEASEEE!!! I DONT UNDERSTAND THIS ONE

In the figure below, m< 1= (x+96)° and m < 2=3x°. Find the angle measure
Answer:
x = 21
Step-by-step explanation:
Angle 1 and angle 2 are supplementary because they make a straight line
so their sum is equal to 180:
m<1 + m<2 = 180
x + 96 + 3x = 180 add like terms
4x + 96 = 180 subtract 96 from both sides
4x = 84 divide both sides by 4
x = 21 to fins the angle measure replace x with the value we found

Write an equation of a line whose slope is 10 and y-intercept is
0
Answer:
y = 10x
Step-by-step explanation:
using slope intercept formula:
y = mx + bHere m, slope is 10, b, y-intercept is 0
so equation:
y = 10x +0
y = 10x
Hello!
Since we have the slope of the line and its y-intercept, we can easily determine its equation:
[tex]\bf{y=mx+b\:\: (Slope-Intercept)[/tex]
M => slope
B=> y-intercept
Now, m=10, and b=0:
[tex]\bf{y=10x+0[/tex]
Final Answer:
[tex]\bf{y=10x[/tex]
I hope it helps you!

In a right triangle, the side that is opposite to a 30 degree angle is equal to half the hypotenuse (you can search it up)
So, the hypotenuse is equal to 3 x 2 = 6
Using the pythagorean theorem, we have :
[tex]x^{2} +3^{2} =6^{2}[/tex]
[tex]x^{2} =6^{2} -3^{2}[/tex] [tex]=36 - 9[/tex] [tex]= 27[/tex]
[tex]x = \sqrt{27}[/tex] [tex]= 5.19615242271...[/tex] (round to 5.2)
Simplify :
[tex]\sqrt{27} = \sqrt{9.3} = 3.\sqrt{3}[/tex]
Given log Subscript 4 Baseline 3 almost-equals 0. 792 and log Subscript 4 Baseline 21 almost-equals 2. 196, what is log Subscript 4 Baseline 7?
Answer:
1.404
Step-by-step explanation:
Given:
[tex]\log_43 \approx 0.792[/tex]
[tex]\log_421 \approx 2.196[/tex]
[tex]\log_421 =\log_4(3 \times 7)=\log_43+\log_47[/tex]
[tex]\implies 2.196\approx 0.792+\log_47[/tex]
[tex]\implies \log_47 \approx 2.196-0.792[/tex]
[tex]\implies \log_47 \approx 1.404[/tex]

As we know that the standard equation of circle is [tex]{\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}[/tex] , where r is the radius of circle and centre at (h,k)
Now , as the circle passes through (2,9) so it must satisfy the above equation after putting the values of h and k respectively
[tex]{:\implies \quad \sf \{2-(-1)\}^{2}+(9-5)^{2}=r^{2}}[/tex]
[tex]{:\implies \quad \sf (3)^{2}+(4)^{2}=r^{2}}[/tex]
[tex]{:\implies \quad \sf 9+16=r^{2}}[/tex]
After raising ½ power to both sides , we will get r = +5 , -5 , but as radius can never be -ve . So r = +5
Now , putting values in our standard equation ;
[tex]{:\implies \quad \sf \{x-(-1)\}^{2}+(y-5)^{2}=(5)^{2}}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{(x+1)^{2}+(y-5)^{2}=25}}}[/tex]
This is the required equation of Circle

There are 8 members of a basketball team . In their last game their mean points scored was 12 . Dom was their best player with 33 points . Dom thinks that if he hadn't played the mean points scored would be 10 . Is Dom right or wrong ? You must explain your answer .
The mean points of the team is the average points per game
Dom's claim is wrong
How to determine if Dom is rightThe number of players in the team is:
n = 8
The mean score per game is:
Mean = 12
The mean of a dataset is calculated as:
[tex]Mean = \frac{Total}n[/tex]
So, we have:
[tex]12= \frac{Total}8[/tex]
Multiply both sides by 8
[tex]Total = 96\\[/tex]
When Dom's point is removed, we have:
[tex]Points = 96 - 33[/tex]
[tex]Points = 63[/tex]
There are 7 players left.
So, the mean point is:
[tex]Mean = \frac{63}7[/tex]
[tex]Mean = 9[/tex]
The mean score is not 10.
Hence, Dom's claim is wrong
