what is the square root of 9/36
Answer:
Exact Form:
1/2
Decimal Form:
0.5
Step-by-step explanation:
(-1-7f)to the power of 2
please explain
Answer:
The product to this problem is simplified to: [tex]1+14f+49f^{2}[/tex]
Step-by-step explanation:
1) First place out what was given:
[tex](-1 -7f)^{2}[/tex]
Squared is the same thing as multiply to itself, so you would create a pair of
[tex](-1 -7f)^{2}[/tex]
(For example, if you said: [tex]x^{2}[/tex] it is the same as saying or putting: x · x)
2) Then create your pair which would look like:
[tex](-1 -7f)(-1 -7f)[/tex]
3) Next step is to do the FOIL method
(The FOIL method is where you do First, Outside, Inside, an Last)(Like how it is shown in the picture, we will do this method and create one whole expression!)
4) Creating and combining your expression into one whole problem, by using the foil method.
[tex](-1 -7f)(-1 -7f)[/tex]
First - F: [tex]1[/tex]
Outside - O: [tex]7f[/tex]
Inside - I: [tex]7f[/tex]
Last: [tex]49f^{2}[/tex]
This will be:
[tex]1+14f+49f^{2}[/tex]
And this will be your answer!
Find the first four terms of the sequence an = 5n-1.
Answer:
let's see what to do buddy...
Step-by-step explanation:
" First four terms " means :
t(1) , t(2) , t(3) , t(4)
[tex]t(1) = a(1) = 5(1) - 1 = 5 - 1 = 4 \\ t(2) = a(2) = 5(2) - 1 = 10 - 1 = 9 \\ t(3) = a(3) = 5(3) - 1 = 15 - 1 = 14 \\ t(4) = a(4) = 5(4) - 1 = 20 - 1 = 19 \\ \\ t(1) = 4 \\ t(2) = 9 \\ t(3) = 14 \\ t(4) = 19[/tex]
So the first four terms
are : 4 , 9 , 14 , 19

A magazine provided results from a poll of 20002000 adults who were asked to identify their favorite pie. Among the 20002000 respondents, 1414% chose chocolate pie, and the margin of error was given as plus or minus±33 percentage points. What values do ModifyingAbove p with caretp, ModifyingAbove q with caretq, n, E, and p represent? If the confidence level is 9999%, what is the value of alphaα?
Answer:
Step-by-step explanation:
Given that:
The sample size n = 2000
The sample proportion [tex]\hat p[/tex] = 0.14
If [tex]\hat p[/tex] = 0.14, then [tex]\hat q[/tex] = 1 - [tex]\hat p[/tex]
[tex]\hat q[/tex] = 1 - 0.14
[tex]\hat q[/tex] = 0.86
The margin of error = 0.03
Given that the confidence interval level = 99%
The significance level is the value of alpha ∝ = 1 - 0.99
∝ = 0.01
Tres amigos quieren rentar una cuatrimoto la cual cuesta $400 por una hora cada uno pone las siguientes cantidades Adriana 50 Luis 160 y Ramiro el resto cuánto tiempo debe subirse cada quien de acuerdo a las recupero con operaciones por favor y una explicación
Answer:
Adriana debe subirse durante 7.5 minutos, Luis durante 24 minutos y Ramiro 28.5 minutos.
Step-by-step explanation:
Asumamos en primer lugar que los tres amigos rentan la cuatrimoto durante una hora, entonces cada persona utiliza la cuatrimoto en proporción al dinero. A continuación, obtenemos el tiempo estimado por cada usuario a partir de una regla de tres simple:
[tex]\Delta t = \frac{c_{a}}{c_{r}}\cdot (60\,min)[/tex]
Donde:
[tex]\Delta t[/tex] - Tiempo de uso de la cuatrimoto, medido en minutos.
[tex]c_{a}[/tex] - Dinero aportado por el usuario, medido en pesos.
[tex]c_{r}[/tex] - Coste de renta de la cuatrimoto, medido en pesos.
Entonces calculamos el tiempo correspondiente a cada amigo:
Adriana ([tex]c_{a} = \$\,50[/tex], [tex]c_{r} = \$\,400[/tex])
[tex]\Delta t = \frac{\$\,50}{\$\,400}\times 60\,min[/tex]
[tex]\Delta t = 7.5\,min[/tex]
Luis ([tex]c_{a} = \$\,160[/tex], [tex]c_{r} = \$\,400[/tex])
[tex]\Delta t = \frac{\$\,160}{\$\,400}\times 60\,min[/tex]
[tex]\Delta t = 24\,min[/tex]
Ramiro ([tex]c_{a} = \$\,190[/tex], [tex]c_{r} = \$\,400[/tex])
[tex]\Delta t = \frac{\$\,190}{\$\,400}\times 60\,min[/tex]
[tex]\Delta t = 28.5\,min[/tex]
Adriana debe subirse durante 7.5 minutos, Luis durante 24 minutos y Ramiro 28.5 minutos.
A=4ℼR2 solve for R
SHOW ALL STEPSSSSSSSSS
Answer:
[tex]R=\frac{1}{2} \sqrt{\frac{A}{\pi }}[/tex]
Step-by-step explanation:
To solve an equation for one of its value
Underline the variable you need to solve for itSeparate this variable on one side and other terms on the other sideMake its coefficient equal to 1∵ A = 4πR²
→ Underline R
∴ A = 4πR²
→ Move 4π to the other side by dividing both sides by 4π
∵ [tex]\frac{A}{4\pi }=\frac{4\pi R^{2} }{4\pi }[/tex]
∴ [tex]\frac{A}{4\pi }=R^{2}[/tex]
→ To find R take √ for both sides
∴ [tex]\sqrt{\frac{A}{4\pi }}=\sqrt{R^{2} }[/tex]
→ You can simplify [tex]\sqrt{\frac{1}{4}}[/tex] to [tex]\frac{1}{2}[/tex]
∴ [tex]\frac{1}{2} \sqrt{\frac{A}{\pi }}=R[/tex]
→ Switch the two sides
∴ [tex]R=\frac{1}{2} \sqrt{\frac{A}{\pi }}[/tex]
Beth is designing a business card. She makes a scale drawing of her old business card by using a scale factor of Five-fourths. Her scale drawing is a 2 and one-half-inch by 5-inch rectangle. The print shop says that the scale drawing is a reduction of the original card because the original card must be 3 and StartFraction 1 over 8 EndFraction inches by 6 and one-fourth inches. Which explains the print shop's error and gives the correct dimensions of Beth's original card?
Answer:
The width and length of the old card are 2 inches and 4 inches respectively.
Step-by-step explanation:
The given scale factor, [tex]C=\frac{5}{4}[/tex]
She draws is a rectangle by using the scale factor of C.
The width of her drawing, [tex]b=2\frac{1}{2}[/tex] [tex]=\frac{5}{2}[/tex] inch, and
the length of the drawing, [tex]a=5[/tex] inch.
Let [tex]a'[/tex] and [tex]b'[/tex] be the length and width of her reference business card (the old one as mentioned).
[tex]\text{Scale factor}=\frac{\text{New dimension}}{\text{Reference dimention}}[/tex]
Here, the dimension is the length of the sides of rectangular cards.
So, [tex]C=\frac{a}{a'}[/tex] and [tex]C=\frac{b}{b'}[/tex]
[tex]\Rightarrow \frac{5}{4}=\frac{5}{a'}[/tex]
[tex]\Rightarrow a'=4[/tex] inch
and [tex]\frac{5}{4}=\frac{5/2}{b'}[/tex]
[tex]\Rightarrow b'=2[/tex] inch
So, the old business card is of the dimensions 2 inches by 4 inches, which are the correct dimensions.
Actually, the print shop multiplied he scale-factor, C, with the new scaled length to get the reference length (lengths of original old card), which was the error. In, fact, as already described earlier, the new dimensions can be obtained by multiplying the scale-factor, C, with the reference dimensions.
Answer:
C. The scale factor is a fraction so the scale drawing is a reduction, and the original card is 2 inches by 4 inches.

Answer:
Step-by-step explanation:
Given the expression [tex]\frac{720,800}{x} = 7.208[/tex], we are to find the value of with powers of 10.
From the equation:
[tex]\frac{720,800}{x} = 7.208[/tex]
cross multiply
[tex]720,800 = 7.208x\\7.208x = 720,800[/tex]
divide both sides by 7.208
[tex]\frac{7.208x}{7.208} = \frac{720,800}{7.208} \\x = 100,000[/tex]
express x in powers of 10
[tex]x = 10 * 10 * 10 * 10* 10\\x = 10^5[/tex]
Similarly given the equation [tex]\frac{720,800}{y} = 72.08[/tex]
From the equation:
[tex]\frac{720,800}{x} = 72.08[/tex]
cross multiply
[tex]720,800 = 72.08x\\72.08x = 720,800[/tex]
divide both sides by 7.208
[tex]\frac{72.08x}{72.08} = \frac{720,800}{72.08} \\x = 10,000[/tex]
express x in powers of 10
[tex]x = 10 * 10 * 10 * 10\\x = 10^4[/tex]
For the equation [tex]\frac{720,800}{z} = 720.8[/tex]
From the equation:
[tex]\frac{720,800}{z} = 720.8[/tex]
cross multiply
[tex]720,800 = 720.8z\\720.8z = 720,800[/tex]
divide both sides by 7.208
[tex]\frac{72.08z}{720.8} = \frac{720,800}{720.8} \\z = 1,000[/tex]
express x in powers of 10
[tex]z = 10 * 10 * 10\\z = 10^3[/tex]
The dividing 720,800 by 101010 successively four times in the parentheses results in 720.8
To complete the equations using powers of 101010:
720,800 ÷ (720,800 ÷ 720,800) = 7.208 = 7.208 equals 7.208
Explanation: Dividing 720,800 by 720,800, and then dividing the result by 720,800, yields 7.208.
720,800 ÷ (720,800 ÷ (720,800 ÷ 101010)) = 72.08 = 72.08 equals 72.08
Explanation: Dividing 720,800 by 101010, and then dividing 720,800 by the result, and finally dividing 720,800 by the new result, gives us 72.08.
720,800 ÷ (720,800 ÷ (720,800 ÷ (720,800 ÷ 101010))) = 720.8 = 720.8 equals 720.8

What would the expression be if the company charged Deborah $45 per hour to repair the computer (plus tax)? (3 pts)
Complete question :
Answer:
Kindly check explanation
Step-by-step explanation:
Given the expression :
Total cost after tax = 0.08(50h) + 50h
a. What part of the expression represents the amount of tax Deborah has to pay? Explain
0.08(50h) represents Tha amount of tax Deborah has to pay. This can be interpreted as :
Recall;
Tax amount = tax rate * cost
Cost of repair = 50h = 50 per hour
Tax rate = 0.08 = 8% of the total cost;
Hence; 0.08(50h) = tax Deborah has to pay.
What would the expression be if the company charged Deborah $45 per hour to repair the computer (plus tax)?
If she was charged $45 per hour plus tax. Expression becomes ;
Total cost after tax = 0.08(45h) + 45h
= 3.6h + 45h
