Answer:
third option
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence, that is
d = - 13 - (- 10) = - 16 - (- 13) = - 3
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 10 and d = - 3, then
[tex]a_{n}[/tex] = - 10 - 3(n - 1) = - 10 - 3n + 3 = - 7 - 3n
Thus the sum of the first 6 terms is represented by
∑ - 7 - 3n ( for n = 1 to 6 )

Plug this number into the next equation and see if it is true
10x + 4 = 34
10(3) + 4 = 34
30 + 4 = 34
34 = 34
This is a true equation, so the the answer is true.
Answer:
True
Step-by-step explanation:
⇒ This is true because the whole equation 10x + 4 = 34 is 2 times more than the other equation 5x + 2 = 17.
⇒ You can see that by multiplying the whole equation 5x + 2 = 17 by 2:
2(5x + 2 = 17)
⇒ To get:
10x + 4 = 34
So both equations are equivalent, which means that the answer is true.

what is m?
please help
Answers
Given:
[tex]\Delta ABC\sim \Delta QRS[/tex]
To find:
The missing value of m.
Solution:
We have,
[tex]\Delta ABC\sim \Delta QRS[/tex]
Corresponding parts of similar triangles are proportional.
[tex]\dfrac{AB}{QR}=\dfrac{AC}{QS}[/tex]
Putting the given values, we get
[tex]\dfrac{m}{10}=\dfrac{2}{4}[/tex]
[tex]\dfrac{m}{10}=\dfrac{1}{2}[/tex]
Multiply both sides by 10.
[tex]\dfrac{m}{10}\times 10=\dfrac{1}{2}\times 10[/tex]
[tex]m=5[/tex]
Therefore, the value of m is 5.

An icecream shop charges $3.39 for a dish of ice cream. A costomer can also order toppings for $0.59 each. If x represents the number, which expression can be used to determine the total charge in dollars, for a dish of ice cream with x toppings
Answers
Answer:
3.39 + 0.59x
Step-by-step explanation:
Cost of a dish of ice cream = $3.39
Cost of toppings = $0.59 each
x = number of toppings
which expression can be used to determine the total charge in dollars, for a dish of ice cream with x toppings
Total charge for a dish of ice cream with x toppings = 3.39 + 0.59x
The expression is 3.39 + 0.59x

Eve is organizing a race to raise money for a local children's hospital. She makes $20 for each 5K participant and $45 for each 10K participant. Her goal is to raise $9,500. If x represents the number of participants in the 5K race and y represents the number of participants in the 10K race, the linear equation for the given scenario is ______________. If Eve raises exactly $9,500, is it possible for there to be 220 participants in the 5K race? (yes or no)
Answers
Answer: [tex]20x +45y=9500[/tex] is the linear equation.
yes, it is possible.
Step-by-step explanation:
given data:
we were told that she would make $20 for each 5K participant and $45 for each 10K participant.
cost of each 5k participant = $20
cost of each 10k participant = $45.
her target = $9500
solution:
let y represent the 10k
let x represent the 5k participant
the linear equation for this scenarios is
[tex]20x +45y=9500[/tex]
(b.) possibility of having 220 participant in the 5k race.
[tex]\\20(220) +45y=9500\\4400 + 45y = 9500\\45y = 9500- 4400\\45y = 5100\\y = \frac{5100}{45} \\y = 113[/tex]
Answer:
Step-by-step explanation:
It is given that x is the number of participants in the 5K race and y is the number of participants in the 10K race.
Eve makes $20 for each 5K participant and $45 for each 10K participant. She wants to raise $9,500. The linear equation below represents the given scenario.
If Eve raises exactly $9,500 and there are 220 5K participants, the number of 10K participants is found as shown below.
It is not possible to have 113.3 participants in the 10K race. So, no, it is not possible for Eve to raise exactly $9,500 if there are 220 participants in the 5K race.

Find the area of a circle with a circumference of \blueD{18.84}18.84start color #11accd, 18, point, 84, end color #11accd units.
Answers
Answer:
28.26 u²
Step-by-step explanation:
What we know:
A circle has a circumference of 18.84 u.
That means the diameter is 6, and the radius is 3.
The area of a circle can be found with: πr²
3.14(3²)
3.14(9)
28.26 u²
The area of the circle is 28.26 square units when the circumference of circle is 18.84 units.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
The circumference of the circle is 18.84 units
We have to find the area of circle
To find area we need to know the radius
Circumference of circle = 2πr
18.84 = 2πr
18.84 = 2×3.14 r
18.84=6.28 r
Divide both sides by 6.28
r=18.84/6.28
r=3
Now let us find area
Area = πr²
=3.14×3²
=9×3.14
=28.26 square units
Hence, the area of the circle is 28.26 square units when the circumference of circle is 18.84 units.
