А
2.5
B
18
с
10.5
D
10
Answer:
d) 10
Step-by-step explanation:
x ÷ [tex]\frac{1}{2}[/tex] + 8 = 13
substitute 10 for x:
⇒ 10 ÷ [tex]\frac{1}{2}[/tex] + 8 = 13
solve:
1) divide 10 by [tex]\frac{1}{2}[/tex]
⇒ 10 ÷ [tex]\frac{1}{2}[/tex] = 5
2) add 8 to 5
⇒ 8 + 5 = 13

Answer:
The center of the circle is point: C=(1,5).
The radius of the circle is r=3.
Step-by-step explanation:
x² + y² -2x - 10y + 17 = 0
Find the center and radius of this circle
We have the equation
x² + y² -2x - 10y + 17 = 0
We collect like terms
x² - 2x + y² - 10y = -17
x² - 2x + (-2/2)² + y² - 10y + (-10/2)² = -17 + (-2/2)² + (-10/2)²
The center of the circle is point: C=(1,5).
The radius of the circle is r=3.

Answer:
x=12
Step-by-step explanation:
Before starting this question, you need to know that the total degree of any given triangle is 180 degrees.
Now looking at the question, we know one side is 90 degree since it is a right triangle.
180-90=90
This let us know that the remaining two angles will have to add up to equal to 90 degrees.
2x+1+5x+5=90
First, combine like terms.
7x+6=90
Now we have to get x by itself, subtract 6 on both sides then divide by 7.
7x=84
x=12

On Saturday, Lucas drove 4x – 5 miles. On Sunday, he drove 3x – 10 miles. What is the difference in miles driven? write an expression and simplify it.
________________________________
Here, Distance covered by Lucas on Saturday
= 4x – 5 miles
Now, Distance covered by Lucas on Sunday
= 3x – 10 miles
________________________________
Hence, Difference between the distances
would be / –
Distance covered on Saturday – Distance covered on Sunday
= (4x – 5) – (3x – 10)
= 4x – 5 – 3x + 10
[ Because (– * + = – ) And ( – * – = +) ]
= 4x – 3x + 10 – 5
= 1x – 5
= x – 5 ( – Ans )
Hence, The difference between Distance covered ( In miles ) is ( x – 5 ) .

Can someone plz help me I beg u :(
please answer :( im very lonely and im bad at maths so do it for me :(((
Answer:
Step-by-step explanation:
First you need to calculate the entire length (in meters) of the metal used in the gate, then multiple the length by 2.5 kg per meter
Break it into parts.......
four pieces on along the outside is just the perimeter of a rectangle
P = 2( L + H) both sides and the top and bottom
the two crossing metal pieces are just the hypotenuse of a right triangle and since we have two pieces of metal
a² + b² = c² or L² + H² = Hyp² solving for the htpotenuse
Hyp = [tex]\sqrt[]{L^2 + H^2}[/tex]
so the total length of the gate metal is
P = 2( L + H) plus 2 Hyp = [tex]\sqrt[]{L^2 + H^2}[/tex]
= 2( 12 + 5) + 2 [ √(12² + 5²) ]
= 34 + 2 [ √( 144 + 25) ]
= 34 + 2 ( √169)
= 34 + 2( 13)
= 34 + 26
= 60 meters of gate metal metal weighs 2.5 kg per meter
Total weight equals 60 meters times 2.5 kg per meter
Total weight = 60 (2.5) = 150 kg

A skyrocket is launched from a 30–foot-high platform, with initial speed 300 ft/s. If the polynomial −16t2 + 300t + 30 gives the height that the rocket will rise in t seconds, how high will a rocket with a 2–second fuse rise? The rocket will rise feet.
Answer:
566 ft
Step-by-step explanation:
Given the polynomial equation
-16t² + 300t + 30 = 0
We're asked to find how high the rocket would rise in a 2 second fuse rise. This is a simple instruction that can be obtained by setting the unknown, t, in the equation to 2. Doing this, we have
-16 * 2² + 300 * 2 + 30
-16 * 4 + 600 + 30
-64 + 630 = 566 ft
Then, we can therefore conclude that the rocket will rise high up to a distance of 566 ft

Answer:
150 boys
Step-by-step explanation:
equation:
⇒ 5x + 4x = 270
add like terms:
⇒ 9x = 270
divide 9 on both sides:
⇒ [tex]\frac{9x}{9} = \frac{270}{9}[/tex]
solve:
⇒ x = 30
take original equation and subtitute 30 for x;
⇒5 x 30 + 4 x 30 = 270
⇒ 150 + 120 = 270
We can see that if there were 270 students, 150 would be boys and 120 would be girls.

Q3. In a hydraulic lift, a 1400 N force is applied to a 0.5 m2 piston. Calculate the minimum surface area of the large piston to lift 5000 N.
Answer:
1.8m^2 approx
Step-by-step explanation:
Given data
P1= 1400N
A1=0.5m^2
P2=5000 N
A2=??
Let us apply the formula to calculate the Area A2
P1/A1= P2/A2
substitute
1400/0.5= 5000/A2
cross multiply
1400*A2= 5000*0.5
1400*A2= 2500
A2= 2500/1400
A2= 1.78
Hence the Area is 1.8m^2 approx
v/22 - 0.1 = 7.4 what is v?
Answer:
v = 165
Step-by-step explanation:
v/22 -0.1 = 7.4
v/22 = 7.4+0.1 =7.5
v = 7.5*22
v = 165
Answer:
[tex]v = 165[/tex]
Step by step Explanations:1) Add 0.1 to both sides.
[tex] \frac{v}{22} = 7.4 + 0.1[/tex]
2) Simplify 7.4 + 0.1 to 7.5.
[tex] \frac{v}{22} = 7.5[/tex]
3) Multiply both sides by 22.
[tex]v = 7.5 \times 22[/tex]
4) Simplify 7.4 × 22 to 165.
[tex]v = 165[/tex]
Therefor, the answer is v = 165.

Question 11 ) Given the following histogram, which term can be used to describe the shape of the data?
PLEASE HELP MY OUT Solve: -2X + 5 +4X + 9 = 3 (6 + 4X) -12X
Show your work
Answer:
x=2
Step-by-step explanation:
first we will distribute out everything
-2x +5 +4x+ 9 = 3(6 +4x)- 12x
(multiply 3 to both 6 and 4x)
-2x +5 +4x+ 9= 18 +12x -12x
then combine like variables on both sides
(add -2x and 4x and add 5 and 9, for the other side add 12x and -12x)
2x+14= 18
then isolate x
2x=4
x=2
and substitute x for 2 to double check
-2(2)+5+4(2)+9=3(6+4(2))-12(2)
18=18
therefore 2 is correct
Find “X” thank you!!!! <33
Answer:
Step-by-step explanation:
If we assume that the angle at A is 90 degrees.. which it does seem like it would be. then use that the sum of the angles around the inside of a right triagle is 180 . so you have
180 = 37 + 90 + x
53° = x

Use mathematical induction to prove the statement is true for all positive integers n. 1^2 + 3^2 + 5^2 + ... + (2n-1)^2 = (n(2n-1)(2n+1))/3)
Answer:
The statement is true is for any [tex]n\in \mathbb{N}[/tex].
Step-by-step explanation:
First, we check the identity for [tex]n = 1[/tex]:
[tex](2\cdot 1 - 1)^{2} = \frac{2\cdot (2\cdot 1 - 1)\cdot (2\cdot 1 + 1)}{3}[/tex]
[tex]1 = \frac{1\cdot 1\cdot 3}{3}[/tex]
[tex]1 = 1[/tex]
The statement is true for [tex]n = 1[/tex].
Then, we have to check that identity is true for [tex]n = k+1[/tex], under the assumption that [tex]n = k[/tex] is true:
[tex](1^{2}+2^{2}+3^{2}+...+k^{2}) + [2\cdot (k+1)-1]^{2} = \frac{(k+1)\cdot [2\cdot (k+1)-1]\cdot [2\cdot (k+1)+1]}{3}[/tex]
[tex]\frac{k\cdot (2\cdot k -1)\cdot (2\cdot k +1)}{3} +[2\cdot (k+1)-1]^{2} = \frac{(k+1)\cdot [2\cdot (k+1)-1]\cdot [2\cdot (k+1)+1]}{3}[/tex]
[tex]\frac{k\cdot (2\cdot k -1)\cdot (2\cdot k +1)+3\cdot [2\cdot (k+1)-1]^{2}}{3} = \frac{(k+1)\cdot [2\cdot (k+1)-1]\cdot [2\cdot (k+1)+1]}{3}[/tex]
[tex]k\cdot (2\cdot k -1)\cdot (2\cdot k +1)+3\cdot (2\cdot k +1)^{2} = (k+1)\cdot (2\cdot k +1)\cdot (2\cdot k +3)[/tex]
[tex](2\cdot k +1)\cdot [k\cdot (2\cdot k -1)+3\cdot (2\cdot k +1)] = (k+1) \cdot (2\cdot k +1)\cdot (2\cdot k +3)[/tex]
[tex]k\cdot (2\cdot k - 1)+3\cdot (2\cdot k +1) = (k + 1)\cdot (2\cdot k +3)[/tex]
[tex]2\cdot k^{2}+5\cdot k +3 = (k+1)\cdot (2\cdot k + 3)[/tex]
[tex](k+1)\cdot (2\cdot k + 3) = (k+1)\cdot (2\cdot k + 3)[/tex]
Therefore, the statement is true for any [tex]n\in \mathbb{N}[/tex].

Answer:7/10
Step-by-step explanation:
Here is the way that I think is the simplest method of changing a percentage a fraction. This percentage has two digits in it, so put it over a 1 and two zeros and then simplify. 35/100 is simplified to 7/20.
