20 POINTS Find the diameter?? Pls help I dont know what to do..
Answer:
Diameter = 19.33
Step-by-step explanation:
Imaging a radius line from O to the endpoints of the 7. call this line R.
Label the part of the vertical line from O to the 90 degree intersection y.
Now you have a right triangle.
Using the Pythagorean theorem:
R² = 7² + y²
also
y = R - 3
substitute for y:
R² = 49 + (R-3)²
R² = 49 + R² - 6R + 9
simplify:
0 = 58 - 6R
6R = 58
R = 9.6667
Diameter = 2(9.6667) = 19.33
Khaya is delivering groceries to his mother who stays 8km from the shop. How long will it take him to cover this distance if he drives at an average speed of 65km/h? Give your answer rounded to the nearest minute.
Answer:
7.385 minutes
Step-by-step explanation:
Given that :
Average speed = 65km/hr
The distance covered = 8km
The time taken Given the information above :
Recall:
Speed = distance / time
Time taken = distance / speed
Time taken = 8km / 65km/hr
Time taken = 0.1230769 hr
Time taken = 0.1230769 * 60 = 7.385 minutes
The time taken to cover this distance is 7.3848 minutes
What is speed?Speed is the change of an object's distance within a specified period of time.
Mathematically, speed can be calculated by using the relation:
Speed = distance/timeFrom the given information:
The average speed = 65 km/hThe distance = 8 kmFrom the above formula, we can make the time the subject of the formula:
Speed = distance/timeBy cross multiplying
Time = distance/speedTime = 8 km / 65 km/hTime = 0.12308 hourWe all know that:
60 seconds = 1 minute60 minutes = 1 hourThus, time(t) = (0.12308 × 60) minutes
Time(t) = 7.3848 minutes

Find the solution to this equation - 3x + 32 - 7x = -2 (5x + 10)
Remember the steps
1. Distribute
2. Combine like terms on the left side
3 Pick sides variables = constants
4 Move terms that don't belong by doing the opposite operations
5 Decide what the statement means If it's always true write "infinitely many solutions." If it's always false, write "no solutions."
Answer:
[tex]x =\frac{-26}{3}[/tex]
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x+32−7x=−2(5x+10)
3x+32+−7x=(−2)(5x)+(−2)(10)(Distribute)
3x+32+−7x=−10x+−20
(3x+−7x)+(32)=−10x−20(Combine Like Terms)
−4x+32=−10x−20
−4x+32=−10x−20
Step 2: Add 10x to both sides.
−4x+32+10x=−10x−20+10x
6x+32=−20
Step 3: Subtract 32 from both sides.
6x+32−32=−20−32
6x=−52
Step 4: Divide both sides by 6.

1. What is the solution of the system
{3x - y = 14
{4x + y = 21 ?
A (−5, 3)
B (4, −2)
C (5, 1)
Answer:
C
Step-by-step explanation:
3x-y=14
4x+y=21
add
7x=35
x=35/7=5
4×5+y=21
y=21-20=1
so (5,1 ) is the solution.
-4x>6y - 54
I’m not sure how to completely solve this
1) Divide both sides by-4.
[tex]x < - \frac{6y - 54}{4} [/tex]
2) Factor out the common term 6.
[tex]x < - \frac{6(y - 9)}{4} [/tex]
3) Simplify 6(y-9)/4 to 3 ( y - 9) / 2.
[tex]x < - \frac{3(y - 9)}{2} [/tex]
Therefor, the answer for x is x < - 3(y - 9)/2.
Solving for Y:[tex] - 4x + 54 > 6y[/tex]
[tex] \frac{ - 4x + 54}{6} > y[/tex]
[tex] \frac{ - 2(2x - 27)}{6} > y[/tex]
[tex] - \frac{2(2x - 27)}{6} > y[/tex]
[tex] - \frac{2x - 27}{3} > y[/tex]
[tex]y < - \frac{2x - 27}{3} [/tex]
Therefor, the answer for Y is y < - 2x-27/3.

IN% of the values are from 4 to 7.
(Type an integer or a decimal.)
Answer:
49.865%
Step-by-step explanation:
Given that:
μ = 4 ; σ = 1
For x = 4
P(x < 4) :
Z score (x - μ) / σ
P(x < 7) - P(x < 4)
((7 - 4) / 1) - ((4 - 4) / 1)
P(Z < 3) - P(Z < 0)
Usibg the Z probability calculator :
0.99865 - 0.5
= 0.49865
= 0.49865 * 100
= 49.865%

i need help with this or else i will not get my computer
Answer:
-26
Step-by-step explanation:
Hello There!
For this problem all we have to do is plug in -5 into x and calculate the value
so..
-3|-5|+2(-5)-1
so first things first | | means absolute value
The absolute values of -5 is 5 so the equation would be
-3(5) + 2(-5) - 1
-3*5=-15
2*-5=-10
-15-10=-25
-25-1=-26
so the answer would be -26
how do you solve fire x.
Answer:
x = 10
Step-by-step explanation:
Sum of all the angle of triangle = 180
71 + 50 + 6x - 1 = 180
71 + 50 -1 + 6x = 180
120 + 6x = 180
6x = 180 - 120
6x = 60
x = 60/6
x = 10
Algebraically, determine the exact value of x for the
equation 85(2)0.4x = 6000.
Answer: 14,575
Step-by-step explanation:
85(2) 0.4x = 6000 Multiply 85 times 2
170 + 0.4x = 6000 Subtract 170 from both sides
0.4x = 5830 Divide 5830 by 0.4
x = 14,575

The length of a rectangle is five more than triple the width. If the perimeter is 154 inches, what are the dimensions
Answer:
Width = 18 inches
Length = 59 inches
Step-by-step explanation:
The length of a rectangle is five more than triple the width. If the perimeter is 154 inches, what are the dimensions
Perimeter of a rectangle = 2L + 2W
The length of a rectangle is five more than triple the width.
L = Length = 5 + 3W
W = Width
If the perimeter is 154 inches, what are the dimensions
Hence,
154 = 2L + 2W
154 = 2(5 + 3W ) + 2W
154 = 10 + 6W + 2W
Collect like terms
154 - 10 = 8W
144 = 8W
W = 144/8
W = 18 inches
Length = 5 + 3W
Length = 5 + 3(18)
Length = 5 + 54
Length = 59 inches
