Answer:
I think 21/12
Step-by-step explanation:
hope it works out,!!
Answer:
Here is the answer 21/12
Step-by-step explanation:
to break 21/12 into a fraction we need to subtract, add a whole.
21-12 is 9 1 9/12
now we need to find a gcf for only 9/12 but divide
this is because the gcf of 4/5 is only 1 so we can’t use it
the gcf for 9/12 is 3
9/12 divided by 3 is 3/4
to know what’s greater I use the butterfly trick Which is sideways multiplying
3. 4
- -
4 5
3 x 5 is 15
4 times 4 is 16
below the 16 should be 4/5
and if you look all the way at the top, it started as 21/12
so it is 21/12
8(y^0) + (-7)(y^0)=________
Answer:
1
Step-by-step explanation:
8(y^0) + (-7)(y^0)
Remove parentheses: (a)=a
= 8[tex]y^{0}[/tex]-7[tex]y^{0}[/tex]
Add similar elements: 8[tex]y^{0}[/tex]-7[tex]y^{0}[/tex]= [tex]y^{0}[/tex]
= [tex]y^{0}[/tex]
Apply rule [tex]a^{0}[/tex] = 1, [tex]\alpha \neq 0[/tex]
= 1

A beaker is completely filled with water
A ball in the shape of a sphere with radius 4 centimeters is placed in the beaker and is completely submerged, causing the volume of water equal to the ball’s volume to overflow.
All of the water that overflows is collected in a funnel in the shape of a cone.
When the funnel is held vertically, the surface of the water collected forms a circle of radius 4 centimeters.
What is the height of the cone formed by the water in the funnel?
Round your answer to the nearest inch.
Answer:6.3 in.
Step-by-step explanation:
Given
Radius of sphere [tex]r=4\ cm[/tex]
When ball is immersed in beaker, it causes the water to flowout of beaker which is collected in the conical vessel
Such that amount of water equivalent to sphere volume is collected in it.
volume of ball
[tex]V_s=\frac{4\pi }{3}r^3[/tex]
[tex]V_s=\frac{4\pi }{3}\times 4^3[/tex]
[tex]V_s=\frac{256\pi }{3}\ cm^3[/tex]
Now volume of water collected is in shape of cone then volume of cone
[tex]V_c=\frac{\pi }{3}r^2h[/tex]
and [tex]V_s=V_c[/tex]
[tex]\frac{256\pi }{3}=\frac{\pi }{3}(4)^2\times h\ quad [\text{h=height of cone formed}][/tex]
[tex]h=4^2=16\ cm\approx 6.29\approx 6.3\ in.[/tex]
If one side of a right triangle is 12 feet long and the hypotenuse of the triangle is 7, find the length of the other side of the right triangle. Round to the nearest hundredth.
I might give you a brainliest if your answer is correct and you have a good explanation.
Answer:
9.74 feet
Step-by-step explanation:
the formula for finding a hypotenuse is [tex]a^{2} + b^{2} = c^{2}[/tex]. We can rearrange that to get: [tex]c^2 - b^2 = a^2[/tex]. So: 49 + b^2 = 144. We get the square root of 95, AKA around 9.74.

Answer:
4, -1
Step-by-step explanation:
2x-3=5
x=4
2x-3=-5
x=-1

Step-by-step explanation:
1 Simplify -2-4−2−4 to -6−6.
2-19-(-6)\times (-5-(-7))\times 22−19−(−6)×(−5−(−7))×2
2 Remove parentheses.

What is the equation, in slope-intercept form, of the line that is perpendicular to the line
y-4 = -(x - 6) and passes through the point (-2, -2)?
o y = x - 10
0 y = x + 10
o y = 2 X-1
O y = x + 1
Answer:
I think it is c
Step-by-step explanation:
I just worked it out but I am not sure if I am 100% right.
hope this helped at all!!!
Answer:
y = 3/2x - 1
Step-by-step explanation:
Slope intercept form = y = mx + b
m = slope of the line = -2/3
y = -2/3x + b
Plug in (-2, -2) and the perpendicular line is
y = 3/2x - 1

For question 25 please pick 1,2,3 or 4

[tex]$x=\frac{2}{3} \pm \frac{1}{6}i \sqrt{158}$[/tex]
Step-by-step explanation:
[tex]18x^2-24x+87=0[/tex]
Using Quadratic Formula
[tex]$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$[/tex]
[tex]$x=\frac{-\left(-24\right)\pm \sqrt{\left(-24\right)^2-4\cdot \:18\cdot \:87}}{2\cdot \:18}$[/tex]
Solving the discriminant:
[tex]\Delta = \left(-24\right)^2-4\cdot \:18\cdot \:87\\\Delta = 576-6264\\ \Delta=-5688[/tex]
[tex]$x= \frac{24 \pm \sqrt{-5688} }{36} $[/tex]
[tex]$x= \frac{24 \pm \sqrt{5688i} }{36} $[/tex]
Once [tex]\sqrt{5688} =\sqrt{2^3\cdot \:3^2\cdot \:79}=6\sqrt{158}[/tex]
[tex]$x=\frac{24\pm6\sqrt{158}i}{36}$[/tex]
Dividing the denominator and numerator by 6
[tex]$x=\frac{4\pm \sqrt{158}i}{6}$[/tex]
Now rewrite it:
[tex]$x=\frac{4}{6} \pm i\frac{\sqrt{158}}{6}$[/tex]
[tex]$x=\frac{2}{3} \pm i \frac{\sqrt{158}}{6}$[/tex]
or
[tex]$x=\frac{2}{3} \pm \frac{1}{6}i \sqrt{158}$[/tex]

Pls help I’ve already tried 3/11 but it says it wrong
Answer:
12
Step-by-step explanation:
Alr so correct me if I'm wrong but I think you made a mistake. It says find 44 of those rectangles. You found just 1 in that case which the area is 3/11. You have to do 3/11 X 44 which is
3/11 x 44/1 = 132/11 = 12.
As I said, correct me if I'm wrong.
Hope this Helps!
Helpppppppp. Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the land has oil. Jason decides to test the land for oil. He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil. What is the probability that the land has no oil and the test shows that it has oil? A. 0.09 B. 0.11 C. 0.36 D. 0.44
Answer:
Jason Inherit a land with a 45% chance of having oil.
Step-by-step explanation:
The probability of the land having oil is = P ( O) = 45 /100
The probability of the land having oil is= Q(O ) =55/100
The machine has an accuracy of 80%. This suggests that 8 out of 10 times the machine will give a wrong reading.
The probability of the correct reading is= P(M)=80/100
The probability of the incorrect reading is=Q(M)=20/100
The case when the machine predicts there is no oil and there is indeed oil can be calculated:Probability=Probability of oil present × probability of the incorrect reading
Probability=P(O) x Q(M)
Probability=45/100 x 20/100
Probability=9/100
The probability of the test predicting no oil in land and the land has oil is 0.09 or 9%

Solve the following equation for x.
7x-3y=-13
Answer:
x = 3/7y - 13/7
Step-by-step explanation:
7x-3y=-13
+3y +3y Add 3y to both sides
7x = 3y - 13 Divide both sides by 7
x = 3/7y - 13/7
x^3/x^1/6=x^a value of a in simplest form?
Answer: a = 17/6
Step-by-step explanation:
I will use two laws of indices to solve this question
1. x^a / x^b = x^(a-b)
2. x^a = x^b, => a = b
Using both laws
x³/x^1/6 = x^a
x^(3-1/6) = x^a
3 - 1/6 = a
a = 3 - 1/6
a = (18 - 1)/6 using LCM
a = 17/6
