Answer: $23,600. ; $318,600
Step-by-step explanation:
From the question, we are informed that a house on the market was valued at $295,000 and after several years, the value increased by 8%.
The value of the increase will be 8% of $295,000. This can be mathematically written as:
= 8% of $295,000
= 8/100 × $295,000
= 0.08 × $295,000
= $23,600
The current value of the house will be:
= $295,000 + $23,600
= $318,600

If £25 = 850 rubles, how many £ are in 1,088 rubles?
Answer:
There are £32.64 are in 1,088 rubles.
Step-by-step explanation:
To solve this
step 1: find cost of 1 rubble
step 2: multiply number of rubble with cost of one rubble.
cost of 850 rubles = £25
we need to find cost of 1 rubles, for that we divide lHS and RHS with 850
cost of 850/850 rubles = £25/850 = £0.03
cost of 1 rubles = £0.03
Therefore cost of 1088 rubles = 1088* cost of 1 rubles
= 1088 * £0.03 = £32.64.
Thus, there are £32.64 are in 1,088 rubles.
The time it takes to set up a circus tent varies inversely with the number E of elephants used. If 4 elephants can set up a tent in 30 hrs how long will it take 2 elephants?
Answer:
It will take 60 hours for 2 elephants to set up the tent.
Step-by-step explanation:
Represent set-up time by T and the number of elephants by E. T varies inversely with E:
T = k/E, or TE = k
If 4 elephants can set up a tent in 30 hours, then 30(4) = k, and
T = 120/E
Now let E = 2. We get T = 120/2, or 60
It will take 60 hours for 2 elephants to set up the tent.
Pat's potato farm grew 490 pounds of potatoes. Pat delivered 3/7 of the potatoes to a vegi stand. The owner of the vigi stand delivered 2/3 of the potatoes he bought to a local grocery store, witch packaged half of the potatoes that were delivered into 5 pond bags. How many 5 pound bags did the grocery store package.
Answer:
14 bags
Step-by-step explanation:
Total potato grown on Pat's potato farm = 490 pound
Fraction of potato delivered to vegi stand = 3/7 of total potato
Therefore,
Potato delivered to Vegi stand in pound = 3/7 of Total potato grown
= 3/7 of 490 = 3/7 * 490
= 210
Thus, 210 pound potato is delivered to vegi stand
___________________________________________
Fraction of potato delivered to local grocery store = 2/3 of potato delivered to Vegi stand
Therefore,
Potato delivered to local grocery store in pound = 2/3 of potato delivered to Vegi stand
= 2/3 of 210 = 2/3 * 210
= 140
Thus, 140 pound potato is delivered to local grocery store.
____________________________________________________
Half of the potatoes delivered were packaged into 5 pound bags
Half of 140 pound potato is delivered to local grocery store will be
140/2 = 70 pounds.
Thus, 70 pounds potatoes were packed in 5 pound bags.
Let the the no of 5 pounds bag be x.
if one bag has 5 pound potatoes then
x bag will have 5*x = 5x pound potatoes,
but it is given that 70 pounds potatoes were packed in 5 pound bags.
thus,
5x = 70
x = 70/5 = 14
Thus, 14 bags were packed by grocery store package.

When she graduated from college, Andrea deposited $2,000 in a savings account that earned 9% simple interest. What was the balance of her accounts after 6 months?
Answer:
$2090
Step-by-step explanation:
The time is 6/12 since it is in months and not years
Interest = [tex]\frac{Principal * Rate * Time}{1}[/tex]
=[tex]\frac{2000 * 9 * 6}{100*12}[/tex]

This means her balance will be $(2000+ 90) = $2090
If x2=y3, what is the value of z does x3z=y9?
If x² = y³ , for what value of z does [tex]x^{3z}[/tex] = [tex]Y^{9}[/tex] ?
Answer:
z= 2
Step-by-step explanation:
To solve the question given, we will follow the steps below;
[tex]X^{3z}[/tex] = [tex]Y^{9}[/tex] -----------------------------------------------------------------(1)
but applying the law of indices mᵃᵇ = (mᵃ)ᵇ
then
[tex]Y^{9}[/tex] = [tex](Y^{3})^{3}[/tex]
replace [tex]Y^{9}[/tex] by [tex](Y^{3})^{3}[/tex] in equation (1)
[tex]X^{3z}[/tex] = [tex]Y^{9}[/tex]
[tex]X^{3z}[/tex] = [tex](Y^{3})^{3}[/tex] --------------------------------------------------------------------(2)
but from the question x² = y³
replace y³ by x² in equation (2)
[tex]X^{3z}[/tex] = [tex](Y^{3})^{3}[/tex]
[tex]X^{3z}[/tex] = [tex](X^{2})^{3}[/tex]
[tex]X^{3z}[/tex] = [tex]X^{6}[/tex]
3z = 6
divide both-side of the equation by 3
3z/3 = 6/3
On the left-hand side of the equation, 3 at the numerator will cancel-out 3 at the denominator leaving us with just z while on the right-hand side of the equation 6 will be divided by 3
z= 2

Answer:
Step-by-step explanation:
Zeros: Set g(r) = (r + 14)^2 - 49 = to 0, obtaining
(r + 14)^2 = 49
Taking the square root of both sides, we get:
r + 14 = ± 7, which results in:
r = -14 + 7 = -7 and r = -14 - 7 = -21
The smaller root is -21 and the larger one is -7.
Vertex: Compare g(r) = (r + 14)^2 - 49 to y = (x - h)^2 + k, where (h, k) represents the vertex. We see that h = -21 and k = -49, so that we know the vertex to be (-21, -49).
What is the measure of U
Answer:
U = 48
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
x+21 + x+23 + x+61 = 180
Combine like terms
3x + 105 = 180
Subtract 105 from each side
3x+105-105 = 180-105
3x = 75
Divide by 3
3x/3 = 75/3
x = 25
We want angle u
x+23
25+23
48
Answer:
48
Step-by-step explanation:
All interior angles of a triangle add up to 180.
[tex](x+21)+(x+23)+(x+61)=180[/tex]
If you wanted to you could subtract 21, 23, and 61 from 180.
[tex](x+21)+(x+23)+(x+61)=180\\x+21+x+23+x+61=180\\3x+105=180\\3x=75[/tex]
Then take then number that's left and divide it by three, since they are all in addition to the same variable.
[tex]\frac{3x}{3}=\frac{75}{3}\\ x=25[/tex]
Then add 25 to 23 which is 48.
