Step-by-step explanation:
i thnk that the answer is .9333 !!
The 4.5 times 10/9 equals 5. In other words, if you multiply 4.5 by 10/9, you get the value of 5.
To find the number that, when multiplied by 4.5, equals 5, we can set up an equation and solve for the unknown number.
Let's represent the unknown number as 'x':
4.5 * x = 5
To isolate 'x', we need to get rid of the coefficient 4.5. To do that, we'll divide both sides of the equation by 4.5:
x = 5 / 4.5
Now, perform the division:
x = 1.111...
The result is a repeating decimal, which means the number that satisfies the equation is 1.111... (with 1 repeating indefinitely).
To express the result more precisely, we can write it as a fraction:
x = 5 / 4.5 = 10 / 9
Therefore, 4.5 times 10/9 equals 5. In other words, if you multiply 4.5 by 10/9, you get the value of 5.

quick and simpler please im practicing this for class
Answer:
a=9/100 b= 7/20
Step-by-step explanation:
For a all you do is take the 9 out of the 100 in 1.
For b, all you do is take the 35/100, and then simplify it, so in this case it is 7/10 if you divide both the numerator and denominator by 5.
So a = 9/100 and b = 7/20

If α , β are roots of x2 + 5x + a =0 and 2α + 5β = -1 then α is equal to _____?
9514 1404 393
Answer:
-8
Step-by-step explanation:
If α and β are roots of x^2 +5x +a = 0, then we must have ...
(x -α)(x -β) = x^2 +5x +a
x^2 -(α+b)x +αβ = x^2 +5x +a
Then ...
α + β = -5
Together with the other relation between the roots, we have a system of equations in α and β.
Using the above to write an expression for β, we get ...
β = -α -5
Substituting this into the given relation, we have an equation for α:
2α +5(-α -5) = -1
-3α -25 = -1 . . . . . . eliminate parentheses
-24 = 3α . . . . . . . . add 3α +1
-8 = α
The root α is equal to -8.
You add 4 drops of food coloring to 2 cups of white frosting and get the orange frosting above. Francisco wants his frosting to be the same color as yours, but he has 5 cups of white frosting. He doesn't know how many drops of orange food coloring to add.
Answer:
Francisco will add 10 drops of food coloring to 5 cups of white frosting and get the orange frosting
Step-by-step explanation:
4 drops of food coloring to 2 cups of white frosting and get the orange frosting.
He has 5 cups of white frosting. He doesn't know how many drops of orange food coloring to add
Let x = drops of food coloring he will add
Drops of food coloring : cups of white frosting
4 : 2 = x : 5
4 / 2 = x / 5
Cross multiplication
4 * 5 = 2 * x
20 = 2x
Divide both sides by 2
x = 20 / 2
= 10
x = 10 drops of food coloring
Therefore, Francisco will add 10 drops of food coloring to 5 cups of white frosting and get the orange frosting

<PQR=134
<SQR=46
Answer:
[tex]\boxed {\angle PQR = 134\textdegree}[/tex]
Step-by-step explanation:
Both angles are Supplementary (Two angles that add up to 180°). So, write an expression using the following measurements of both [tex]\angle PQR[/tex] and [tex]\angle RQS[/tex] and 180:
[tex]\angle PQR = 3x + 5[/tex]
[tex]\angle RQS = x + 3[/tex]
[tex]3x + 5 + x + 3 = 180[/tex]
Solve:
[tex]3x + 5 + x + 3 = 180[/tex]
[tex]4x + 5 + 3 = 180[/tex]
[tex]4x + 8 = 180[/tex]
[tex]4x + 8 - 8 = 180 - 8[/tex]
[tex]4x = 172[/tex]
[tex]\frac{4x}{4} = \frac{172}{4}[/tex]
[tex]x = 43[/tex]
-After you have the value of [tex]x[/tex], use it to the expression of [tex]\angle {PQR}[/tex] to get the actual answer of [tex]\angle PQR[/tex]:
-The value of [tex]x[/tex]:
[tex]x = 43[/tex]
-Solve for the measurement of [tex]\angle PQR[/tex]:
[tex]3x + 5[/tex]
[tex]3(43) + 5[/tex]
[tex]129 + 5[/tex]

-The measurement of [tex]\angle PQR:[/tex]
[tex]\boxed {\angle PQR = 134\textdegree}[/tex]

A kilogram of potatoes cost $25.A dozen bananas cost $40.
a) Write an algebraic expression for the total cost of n kilograms of potatoes and one dozen bananas.
b) Evaluate your expression to determine the cost of 15kg of potatoes and one dozen bananas
Answer:
a) T = 25n + 40
b) T = $415
Step-by-step explanation:
The total cost of 'n' kilograms of something can be expressed as 'n' multiplied by the cost, since it is a constant cost per unit. Therefore the price for n kg of potatoes can be expressed as 25n. We are also told that a dozen bananas cost $40, so our expression is the cost of potatoes added to the cost of bananas. So, is we use 'T' for total cost, our expression will look like this:
T = 25n + 40
Now we can use this expression to find the cost of 15kg of potatoes and the same amount of bananas. We can do this by simply substituting the given amount for n:
T = 25(15) + 40
T = 375 + 40
T = $415
The cost of 15kg of potatoes and one dozen bananas is $415.
Hope this helped!

Find the value of X in the triangle shown below.
Answer:
x = 33°
Step-by-step explanation:
All angles in a triangle add up to 180°.
Step 1: Set up equation
x + 114 + 33 = 180
Step 2: Solve for x
Combine like terms: x + 147 = 180Subtract 147 on both sides: x = 332. What are the angle measures of the triangle?

Ariana is going to invest in an account paying an interest rate of 1.9% compounded monthly. How much would Ariana need to invest, to the nearest ten dollars, for the value of the account to reach $110,000 in 14 years?
Answer:
110000=p(1+0.019)^168
23.62p=110000
p=4660
credit: sqdancefan
Answer:
84330
Step-by-step explanation:
The compound interest formula gives the value of an investment.
A = P(1 +r/n)^(nt)
where principal P is invested at annual rate r compounded n times per year for t years. Using your given values, we can solve for P.
110,000 = P(1 +0.019/12)^(12·14)
P = 110,000/(1 +0.019/12)^(12·14) ≈ 110,000/1.00158333...^168
P ≈ 110,000/1.30446
P ≈ 84326.04 ≈ 84,330 . . . . dollars
