Answer:
2*7=8*10
Step-by-step explanation:
Because x=2,y=7 and x=8,y=10
So x*y=x*y
Two highways meet at right angles in a town. Both highways are exactly straight
lines. Two cars leave the intersection at exactly the same time. One car starts traveling East
at 40mph and is decelerating at a rate of 1mph per hour. The other car starts traveling North
at 30mph and is accelerating at a rate of 0.5mph. At what rate is the distance between them
increasing 4 hours after they leave the intersection?
Answer:
Step-by-step explanation:
Using the relation :
S = ut + 1/2at²
S = distance
Car A :
Initial speed, u = 40 mph
a = negative acceleration = - 1 mph
At time, t = 4
S = 40(4) - 0.5(1)(4²)
S = 160 - 8
S = 152 miles
Car B :
Initial speed, u = 30 mph
a = acceleration = 0.5 mph
S = 30(4) - 0.5(1)(4²)
S = 120 - 8
S = 118 m
Change in distance / time
Rate of change = (152 - 118)m / 4 hours
Rate of change = 34 mi / 4 hr
Rate of change = 8.5 miles per hour
find the answer to these problems:
36 = 4x
13 = x +5
3x = 21
28 = x
8x = 60
Nevada has the fastest growing population according to the U.S. Census bureau. In 2004, the population of Nevada was 2.62 million and increasing at an annual rate of 3.5%. What is the expected population 2010 ? Apply the population growth formula N=Noe^rt
Answer:
32,322,237 million or 3.23million
Step-by-step explanation:
Nevada has the fastest-growing population according to the U.S. Census bureau. In 2004, the population of Nevada was 2.62 million and increasing at an annual rate of 3.5%. What is the expected population in 2010? Apply the population growth formula N=Noe^rt
Applying the formula given above
N=Noe^rt
No = 2.62 million
r = 3.5% = 0.035
t = 2010 - 2004 = 6 years
N = 2.62 × e^6 × 0.035
N = 3.2322365171 million
= 32,322,237 millon
Approximately = 3.23 millon

10. Damarion is finding measurements from the triangular prism shown.
a. Damarion finds the perimeter of the base to be 48 units.
Explain his error.
b. Damarion finds the area of the base to be 96 units2.
Explain his error
Answer:
The answer is "32 and 48"
Step-by-step explanation:
Please find the graph file in the attached file.
The perimeter is= sum of sides
[tex]= 10+10+12 \\\\ =32 \ units\\\\[/tex]
Calculating the Area of base[tex]= \frac{1}{2} \times base \times height[/tex]
[tex]= \frac{1}{2} \times 12 \times 8\\\\= \frac{1}{2} \times 96\\\\=48 \ units^2[/tex]

Christine bought 9m ribbon lace for her school project. One yard of the lace cost P5.00
How much did Christine pay in all?
Step-by-step explanation:
Given 1 yard = 0.9144m
0.9144 m = 1 yard
1 m = 1/0.9144 yards = 1.094yards
9m = 9 x 1.094 yards = 9.846yards
given 1 yard = P5.00
9.846 yards = P5.00 x 9.846 = P49.23
The temperature of a city is 4⁰C. Next day , the temperature falls by 5⁰C. What is the temperature of the city next day?
Answer: -1 degree celcius
Step-by-step explanation:
The temperature on the first day is 4 degrees celcius.
The temperature on the second day falls by 5 degree celcius.
Therefore, we subtract 5 from 4 which gives us -1.

(WILL GIVE BRAINLIEST TO EVERY QUESTION ANSWERED ON MY PROFIL) Debra Goforth’s savings account shows a balance of $904.31 on March 1st. The same day, she made a deposit of $375 to the account. She also made deposits of $500 on April 1st and May 1st. The bank pays an annual interest rate of 5.5 percent. Use your Compounded Daily chart to calculate the amount in her account on May 29th.
Answer:
$4625.10
Step-by-step explanation:
Her account already had $904.31
You now need to add $375.
Then add $500 twice.
Because of how banks work, we need to find out how much they pay monthly. There are 12 months in a year. 5.5 divided by 12 is 0.45.
45% of 1279.31 is 575.68
Now we add the $575.68 to $1279.31
April is a new month and she deposited $500.
45% of 1854.99 is 834.74
Add $834.74 to $1854.99
Then she deposits 500 on May, another new month.
I think this step is obvious. Just follow what you did last time.
This leaves her with $4625.10

Solve the triangle. Round to the nearest tenth when necessary or to the nearest minute as appropriate.
Answer:
Following are the responses to the given question:
Step-by-step explanation:
[tex]\angle C= 180 - ( 26 + 51 )\\\\C = 103^{\circ}[/tex]
applying the law of sines to find the unknown sides:
[tex]\to \frac{a}{\sin A} = \frac{c}{\sin C}\\\\\to \frac{a}{\sin 26} = \frac{28}{\sin 103}\\\\a=\frac{28 \times \sin 26 }{\sin 103}\\\\a=\frac{28 \times 0.438371147 }{0.974370065}\\\\a=\frac{12.2743921 }{0.974370065}\\\\a=12.597259\\\\a=12.59\\\\a = 12.6 \ m\\\\[/tex]
[tex]\to \frac{b}{\sin 51} = \frac{28}{\sin 103}\\\\\to b=\frac{28 \times \sin 51 }{\sin 103}\\\\b=\frac{28 \times 0.777145961 }{0.974370065}\\\\b=\frac{21.7600869 }{0.974370065}\\\\b=22.3324681\\\\b=22.3\\\\b = 22.3 \ m\\\\[/tex]
so,
[tex]\angle C = 103^{\circ}\\\\\to AC = 22.3\ m\\\\\\to BC = 12.6 \ m[/tex]

Determine whether the function represented by each equation is quadratic. F(x)=0.01-0.2x+x^2
-
I tried but couldnt quitw solve it :(
Answer: x=0.1
Step-by-step explanation:
Given
The function is given by [tex]F(x)=x^2-0.2x+0.01[/tex]
A standard quadratic equation is given by [tex]ax^2+bx+c=0[/tex]
The given equation has an exponent of x as 2 which confirms it is a quadratic equation. Compare it with the standard equation
[tex]a=1,b=0.2,c=0.01[/tex]
Therefore, the given equation is the quadratic equation.
Its solution is given by
[tex]\Rightarrow x=\dfrac{0.2\pm \sqrt{(-0.2)^2-4\times 1\times 0.01}}{2\times 1}\\\\\Rightarrow x=0.1[/tex]

HELP
Answer:
[tex]2x+3y\geq 60\\x>10[/tex]
Step-by-step explanation:
We know that she will be selling bracelets for $2 each and earrings for $3 each. That means we will have 2x+3y, where x is the number of bracelets she sells and y is the number of earrings she sells. Then we will have [tex]\geq 60[/tex] because she wants to sell at least $60 worth of earrings and bracelets. That means the amount she makes from bracelets and earrings combined has to equal 60 or more, thus we use the greater than or equal to sign.
Now we have [tex]x>10[/tex], where x is still the number of bracelets sold. She said she will sell more than 10, which means we will just have [tex]>10[/tex]. If she said she wanted to sell at least 10, then it would be [tex]\geq10[/tex].
Therefore the system of inequalities is:
[tex]2x+3y\geq60\\x>10[/tex]
Hope this helps!
