Step-by-step explanation:
common difference is 7
first term of the sequence is 24
by explicit formula a1 + ( n- 1)*d
24 + (1000-1)*7
24+999*7

Answer:the pair of simultanous equations that model Andy's and Ron's ages are
3A-2R=6----Equation 1
R-A =2----Equation 2
Andy is 10 Years and Ron is 12 years
Step-by-step explanation:
Andy's age is represented as A
and Ron';s age is represented as R
Now if Andy multiplies his own age by 3. He then subtracts twice Ron's age. The answer is 6 can be expressed mathematically as
3A-2R=6
And if Ron subtracts his age from Andy's age. The answer is −2 can be expressed as
R-A =2
Therefore the pair of simultaneous equations that model Andy's and Ron's ages are
3A-2R=6----Equation 1
R-A =2----Equation 2
Solving becomes
3A-2R=6----Equation 1
R-A =2----Equation 2
Make R subject formulae in equation 2
R =2+A
Putting R =2+A in equation 1
3A-2(2+A)=6
3A -4-2A =6
A-4=6
A=6+4=10
From eqn 2,
R-A =2
R-10 =2
R=10+2=12
Andy is 10 Years and Ron is 12 years
Answer:
The correct option is 3. The length of XC is 30.
Step-by-step explanation:
It is given that triangle ABC and triangle XYC are similar.
According to the properties of similar triangles, then corresponding sides of similar triangles are congruent.
In triangle ABC and triangle XYC,
Let the length of XC be x.
From the below figure it is notices that
Therefore correct option is 3. The length of XC is 30.
The volume of the given figure is 104 m³.
We need to find the volume of the given figure.
<h3>What is volume?</h3>
Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.
Divide the given figure into two convenient cuboids. That is one with dimensions length=4 m, breadth=4 m and height=3 m. Another with length=4 m, breadth=7 m and height=2 m.
We know that, the volume of cuboid =l×b×h cubic units.
Now, the volume of cuboid=4×4×3=48 m³ and the volume of another
cuboid=4×7×2=56 m³.
The volume of the given figure=48+56=104 m³.
Therefore, the volume of the given figure is 104 m³.
