Answer:
x = 0 , y = 8
Step-by-step explanation:
x = y - 8 -----(1)
7x + 2y = 16 --------(2)
Substitute (1) in (2)
7(y - 8) + 2y = 16
7y - 56 + 2y = 16
9y = 72
y = 8
Substitute y in (1)
x = 8 - 8 = 0

A 170 ft string attached to a kite makes a 40⁰ angle with the ground. What is the height of the kite to the nearest tenth? 130.2 ft 33 ft 142.6 ft 109.3 ft
Answer:
109.3 ft
Step-by-step explanation:
Remembering SOHCAHTOA
We would be using sin
sin = opposite / hypotenuse
sin 40 = x / 170
0.6428 = x/170
x = 0.6428 x 170 = 109.3 ft
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
A number is chosen at random from 6 to 25. Find the probability of selecting an even number or multiple of 3.
Answer:
17/25
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
even numbers between 6 and 25 = 6 8 10 12 14 16 18 20 22 24
multiples of 3 = 6 9 12 15 18 21 24

Un cuerpo de 180 kg se debe lanzar hacia una distancia de 25 m. ¿Qué valor tiene el trabajo que se realiza al lanzarlo?
Answer:
45, 000 J o 45 KJ
Step-by-step explanation:
Recordemos que trabajo realizado = fuerza * distancia
En este caso, fuerza = peso del objeto
Por lo tanto, peso del objeto = 180 Kg * 10ms ^ 2 = 1800 N
Por eso;
Trabajo realizado = 1800 N * 25 m = 45, 000 J o 45 KJ

A. The difference of a number and twelve.
B. The product of a number and twelve.
C. The quotient of a number and twelve.
D. The sum of a number and twelve.
Answer: D) The sum of a number and twelve
==================================================
Explanation:
r = an unknown number
r+12 = sum of the unknown number and 12
The term "sum" refers specifically to the result of an addition problem.
As another example, saying 2+3 = 5 has a sum of 5.
Jorge's friend Kylie has a garden with 100 flowers in it. Kylie's garden contains tulips and daisies. Is it possible for Kylie's garden to have the same ratio of tulips to daisies as Jorge's garden? Explain why or why not.
Answer:
Yes, Kylie's can have the same ratio of tulips to daisies as that of Jorge
Step-by-step explanation:
Complete question
Jorge planted flowers in his garden. He planted one row of 12 tulips
and one row of 36 daisies. Jorge's friend Kylie has a garden with 100 flowers in it. Kylie's garden contains tulips and daisies. Is it possible for Kylie's garden to have the same ratio of tulips to daisies as Jorge's garden? Explain why or why not
Solution
Ratio of Tulip to daises in Jorge garden is 12:36 = 1:3
Here the common factor is 12 for numerator and denominator i.e 4 * 3 or 2, 2, 3
Given, Jorge's friend Kylie has a garden with 100 flowers, 100 is divisible by 4 but not 3.
Hence, if we take Ratio of Tulip to daises in Jorge garden as 3:9 (by only removing common factor 4), then the Ratio of Tulip to daises in Kylie garden will have the same ratio is that of Jorge'sgarden

A triangle has side lengths of
3, 7, and 10
Answer:
Possible
Step-by-step explanation:
The rule for triangle side lengths is that the two shortest sides must add up to the longest side so it is possible because
3+7 = 10
Two short sides = The longest side
Answer:
possible
Step-by-step explanation:
3+7= 10
A store was trying to sell a bed set for 475$. After a while, they marked the price tag down 35%. If tax is 5% (of the sale price) how much would the bed cost
Answer:
$324.19
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Price = $475
Price tag down = 35%
Tax = 5%
So, price after tag down = $475 - ( $475 × 35%)
= $475 - $166.25 = $308.75
Now, we calculate tax value after price tag down,
Tax value = $308.75 × 5% = $15.44
So, we can calculate the bed cost by using following formula,
Bed cost = Price after tag down + Tax value
= $308.75 + 15.44
= $324.19

i cant resolve this equation : 2x = -2x + 8, can you help me please
Answer:
x = 2
Step-by-step explanation:
OK so lets do it together.
2x = -2x + 8
Subtract 8 from both sides
2x - 8 = -2x
Add 2x to both sides
4x - 8 = 0
Add 8 to both sides
4x = 8
Divide each side by 4
x = 2
Check:
4 = -4 + 8
4 = 4
correct

Which equation is equivalent to 23x= 10?
log, 10 = 30
log, 3x = 10
log 2 = 30
log 3.0
2
After applying some properties of logarithm the correct expression for the given logarithmic equation we get is 3x = log₂ 10.
Use the concept of logarithm defined as:
The logarithmic function is the opposite of the exponentiation of that function.
It can be mathematically defined as:
For [tex]x > 0 , a > 0[/tex], and [tex]a\neq1[/tex],
[tex]y= log_a x[/tex] if and only if x = ay
Then the function is given by
[tex]f(x) = log_a x[/tex]
Where a is the base of function.
The given expression is:
[tex]2^{3x} = 10[/tex]
Take log both sides,
[tex]\text{log } 2^{3x} = \text{log } 10[/tex]
Since we know that,
[tex]\text{ log} a^n = n\text{ log} a[/tex]
Therefore,
3x log 2 = log 10
Dividing both sides by 2
3x = log10/log2
Since we know that,
[tex]\text{log} _a b = \dfrac{\text{log}_c b}{\text{log}_c a}[/tex]
Therefore,
3x = log₂ 10.
Hence,
The correct expression is 3x = log₂ 10.

Answer: 9.7
Step-by-step explanation: I got this question right
70+30 = 100
B = 180 - 100 - 20
B = 60°
80+20 = 100
C = 180 - 100 - 30
C = 50
DB/sin100 = 8/sin(60)
8*sin(100)/sin(60)
DB = 9.0973
DC/sin(30) = 8/sin(50)
8*sin(30)/sin(50)
DC = 5.22163
x = [tex]\sqrt{5.22163^{2} +9.0973^{2} -2*5.22163*9.0973*cos(80)[/tex]

Part II: Using the variable you defined in Part I, write an expression to represent the
amount of money Sam will spend in one year (Sam's cost). (2 points)
Answer:
Number of wooden carving = a
Total amount Sam spend = 1,200 + 4a
Total revenue of Sam = 15a
Number of wooden carving make to earn profit $4,300 = 500 carvings
Step-by-step explanation:
Given:
Sales price of each wooden carving = $15
Fixed cost = $1,200
Variable cost = $4 for each
Find:
Number of wooden carving make to earn profit $4,300
Computation:
Part 1
Assume
Number of wooden carving = a
Part 2
Total amount Sam spend = 1,200 + 4a
Part 3
Total revenue of Sam = 15a
Part 4
Total profit of Sam = Total revenue of Sam - Total cost of Sam
4,300 = 15a - [1,200 + 4a]
4,300 = 15a - 1,200 - 4a
11a = 5,500
a = 5,500 / 11
Number of wooden carving make to earn profit $4,300 = 500 carvings
