Answer:
1. [tex]Area = 28.26[/tex]
2 and 3: See explanation
Step-by-step explanation:
Solving (1)
[tex]r = 3[/tex] --- radius
The area is:
[tex]Area = \pi r^2[/tex]
[tex]Area = 3.14* 3^2[/tex]
[tex]Area = 28.26[/tex]
There are no enough information to solve (2) and (3) as the radius and/or diameter are not provided.
However, the following formula will be used to calculate the required areas.
[tex]Area = \pi r^2[/tex] --- same process as (1)
can someone pls help for brainlest
Answer:
a = 6
Step-by-step explanation:
Area = 36 [tex]in^{2}[/tex]
Only one number will make this missing length true.
Obviously it's a square so one number x one number will equal to 36 [tex]in^{2}[/tex]
6 x 6 = 36 [tex]in^{2}[/tex]
Answer:
The missing length of square is 6 in.
Step-by-step explanation:
Here we have given the area of square = 36 in ²
We need to find the missing length of square .
note :- missing length = side all side of square are equal.Using formula
Area of square = ( side ) ²
put the values
36 in² = ( side)²
Finding the square root of 36 in²
√36 in ² = side
6 in = side
Hence, the side of square is 6 in.

Answer:
Step-by-step explanation:
Gabriela has solved incorrectly. 5 should distributed to 9x & (-8) and 4 should be distributed between x & 2
5(9x - 8) = 4*(x + 2)
5*9x - 5*8 = 4*x + 4*2
45x - 40 = 4x + 8
Subtract 4x from both sides
45x - 4x - 40 = 8
41x - 40 = 8
Add 40 to both sides
41x = 8 + 40
41x = 48
x = 48/41
If c=8, what is the value of 4c+(4-3)
Answer:
[tex]33[/tex]
Step-by-step explanation:
[tex]c = 8 [/tex]
Substitute 8 in the equation where c is.
[tex]4(8) + 4 - 3 \\ 32 + 1 \\ = 33[/tex]
is (0,0) a solution to x + y > 5 , 2x - y < 4
Answer:
(0,0) is not a solution to x + y > 5 , but it is a solution for 2x - y < 4
Step-by-step explanation:
Substitute x=0,y=0
0>5 (not possible)
0<4(possible)
if a dog drinks 8 quart of water a day, how many gallons does the dog drink in 3 days
Answer:
6 gallons
Step-by-step explanation:
There are 4 quarts in gallons, so the dog drinks 2 gallons a day.
When we multiply 2 and 3, we would get 6.
So the dog drinks 6 gallons in 3 days (I don't know about you, but that's a lot of water)
---------------------------------------------------------------------------------------------------------------
Have a great summer :)
Answer:
The dog will drink 6 gallons.
Step-by-step explanation:
Every 8 quarts is 2 gallons.
Multiply 2 by 3, you'll get 6.
that's how much gallons a dog drinks in 3 days.
What is the total surface area of the square pyramid?
Answer:
D
Step-by-step explanation:
[tex]A_1 = a^2 = 14^2 = 196[/tex]
[tex]A_2 = 4(\frac{b * h}{2}) = 4(\frac{14 * 12}{2}) = 4(\frac{168}{2}) = 4 * 84 = 336[/tex]
[tex]SA = A_1 + A_2 = 196 + 336 = 532\ cm^2[/tex]

What is the slope of the line? 4x-1=3y+54x−1=3y+54, x, minus, 1, equals, 3, y, plus, 5 Choose 1 answer: Choose 1 answer: (Choice A) A \dfrac23 3 2 start fraction, 2, divided by, 3, end fraction (Choice B) B \dfrac34 4 3 start fraction, 3, divided by, 4, end fraction (Choice C) C \dfrac32 2 3 start fraction, 3, divided by, 2, end fraction (Choice D) D \dfrac43 3 4
Answer:
Slope of the line, m = 4/3
Step-by-step explanation:
Given;
4x - 1 = 3y + 5
Make y the subject
4x - 1 = 3y + 5
4x - 3y = 5 + 1
4x - 3y = 6
-3y = 6 - 4x
Divide both sides by -3
y = (6 - 4x) / -3
y = -2 + 4/3x
Slope intercept form is given by
y = mx + b
Where,
m = slope
y = - 2 + 4/3x
m = 4/3
Slope of the line, m = 4/3
Answer:
Above answer is INCORRECT.

ABC is a right angled triangle
AC=6cm
AB=20cm
Calculate length of BC
Give answer to 1 decimal place
Answer:
19.1cm
Step-by-step explanation:
AB=20
AC=6
BC=?
So,by Pythagoras Theorem:-
AC2=AB2+BC2
Therefore:-
AB2-AC2=BC2
400-36=BC2
√364=BC2
19.1=BC2
Answer:
19.1 cm
I don't have a picture so I hope this is what you mean/
Step-by-step explanation:
AB²-AC²=BC²
20²-6²=BC²
400-36=BC²
364=BC²
√364=√BC²
BC≈19.1

Answer:
18.9
Step-by-step explanation:
First, lets solve for the fractions. You can divide the fractions from the top, to their bottom (4 divided by 5, 3 divided by 5), in this case, you get 1.4. Now you have to rewrite the problem: 1.4+3.5x5. You solve it, and get 18.9.
Answer:
18.9

Plot the coordinates of the point:
(a) whose co-ordinate is -5 and which lies on y axis.
(b) Which lies on x and y-axis both.
(c) whose abscissa is 3 and which lies on x-axis in cartasian plance.
Answer:
First, a regular point is written as a coordinate pair (x, y).
If the point lies on the x-axis, then we have y = 0
if the point lies on the y-axis, then x = 0
And x is the abscissa, y is the ordinate.
The points will be graphed at the end.
a)
Ordinate = -5, then y = -5
and it ies on the y-axis, then x = 0
So this point is represented by A = (0, -5)
b)
Lies on the y-axis and in the x-axis, then x = 0 and y = 0, so the point is represented by B = (0, 0)
c)
The abscissa is 3, so x = 3, and the point lies on the x-axis, so y = 0
Then this point is represented by C = (3, 0)
The graph with the 3 points are:

Answer:
[tex]\small{\boxed{\tt{2 \sqrt{5} (13 + \sqrt{2} = 26 \sqrt{5} + 2 \sqrt{10} = 64.3}}}[/tex]
Step-by-step explanation:
Given : Expression
[tex]2 \sqrt{5} (13 + \sqrt{2} )[/tex]
To find : Simplify the expression
Solution :
Step 1 - Write the expression
[tex]2 \sqrt{5} (13 + \sqrt{2} )[/tex]
Step 2 - Apply distributive property,
[tex]a(b + c) = a × b + a \times c[/tex]
[tex] = 2 \sqrt{5} \times 13 + 2 \sqrt{5 } \times \sqrt{2} [/tex]
Step 3 - Apply square root property,
[tex] \sqrt{x} \times \sqrt{y} = \sqrt{xy} [/tex]
[tex] = 26 \sqrt{5} + 2 \sqrt{10} [/tex]
or to simplify more substitute the value of [tex] \sqrt{5} = 2.23[/tex] and [tex] \sqrt{10} = 3.16[/tex]
Simplification-
[tex] = 26(2.23) + 2(3.16)[/tex]
[tex]= 57.98 + 6.32[/tex]
[tex]= 64.3[/tex]

A map has a scale of 2 inches : 25 miles. Chandra uses the map to find the distance from the zoo to her house. The distance on the map is 5 inches. How many miles away is the zoo from Chandra’s house?
Step-by-step explanation:
Turn the ratio into a fraction
2in /25 mi
You want to have miles so you can flip the fraction and mutiply to cancel out the inches
(25mi / 2in) x 5in = (25 mi x 5in) / 2in

A group of people were asked how many people live in their household. What percent of these people have exactly 2 people in their household?
Answer:
16%
Step-by-step explanation:
Given
[tex]\begin{array}{cccccc}{Size & {1} & {2} & {3} & {4} & {5} \ \\ {f} & {3} & {4} & {6} & {7} & {5} \ \end{array}[/tex]
Required
The percentage of household with 2 people
First, calculate the total frequency
[tex]Total = 3 + 4 +6+7+5[/tex]
[tex]Total = 25[/tex]
The frequency of household with 2 people is:
[tex]f(2) = 4[/tex]
So, the percentage is calculated as:
[tex]\% =\frac{f(2)}{Total} * 100\%[/tex]
[tex]\% =\frac{4}{25} * 100\%[/tex]
[tex]\% =\frac{400}{25}\%[/tex]
[tex]\% =16\%[/tex]
Players on a volleyball team wear jerseys numbered 1 through 9. In how many different ways could you arrange 5 of the players?
a
15,120
b
120
c
362,880
d
24
Answer:
Total number of arrangements for 5 players = 15,120 arrangements
Step-by-step explanation:
Given:
Number given from 1 to 9
So,
Total number for jerseys = 9
Find:
Total number of arrangements for 5 players
Computation:
Total number of arrangements for 5 players = 9! / [9! - 5!]
Total number of arrangements for 5 players = 9 x 8 x 7 x 6 x 5
Total number of arrangements for 5 players = 15,120 arrangements

find the time in which a train of length 132 M will cross and electric post if the speed of the train be to 6.4 km /hour
Answer:
It will take the train 1.2375 minutes to pass the tunnel
Step-by-step explanation:
Mathematically, we know that ;
time = distance/ speed
The distance here is the length of the train which is 132 m ; we can convert this to km by dividing by 1000
We have this as 132/1000 = 0.132 km
So, we have the time as;
0.132 km/6.4 km/hr = 0.020625 hr
Mathematically, we know that 60 minutes make an hour;
so we have
0.020625 * 60 = 1.2375 minutes
