6.09 to the nearest tenth.
Answers
Answer:
6.1
Step-by-step explanation:
So when rounding off to the earest tenth check if the hundredeth number is bigger than 5 in this case the 9 is bigger than 5.
Because it is bigger than 5 add a 1 to the tenth unit making it 1.
Leave the 6 as it is.
The answer then becomes 6.1

The midpoint of FG is (6-4) and the coordinates of point Fare (-3, 6) What are the coordinates of point G?
Answers
Answer:
(15,-14)
Step-by-step explanation:
Given that,
The midpoint of FG is (6-4) and the corrdinates of F are (-3,6).
Let (x,y) be the coordinates of point G. Using mid point formula,
[tex]\dfrac{x+(-3)}{2}=6\ \text{and}\ \dfrac{y+6}{2}=-4\\\\x-3=12\ \text{and}\ y+6=-8\\\\x=15,\ \text{and}\ y=-14[/tex]
So, the coordinates of G are (15,-14).
A local drugstore sells tissues at 10 boxes for $7.50. A super discount
warehouse sells the same tissues at 30 boxes for $22.00. Which store has a
better offer?
Answers
Answer:
The local drugstore
Step-by-step explanation:
The local drugstore sells 10 boxes for 7.50. You would do 10/7.50 = 1.34
The local drugstore sells every box for 1.34
The warehouse sells 30 boxes for 22.00. 30/22 = 1.36. Each box at the warehouse cost 1.36
The local drugstore is cheaper and a better sale. The drugstore is 0.02 cheaper.
Last year you bought a pair of boots for $84 last year. Your friend bought the same pair of boots this year for $120. What is the percent of change in the cost of the boots.
Answers
Answer:
30%
Step-by-step explanation:
70% of 120 is 84. So take the remainder of 70 (30, as %'s go up to 100.) and that's the percent left. We can "fact check this" the other way around as well.
30% of 120 = 36.
84 + 36 = 120.
The price of the boots have changed/raised 30%.

please help
Answers
Answer:
The function is not one-to-one
Step-by-step explanation:
Required
Determine if [tex]f(x) = round(x)[/tex] is one-to-one
To answer this question, we need to make use of illustrating values of x.
Take x = 6.7
This implies that:
[tex]f(6.7) = round(6.7)[/tex]
[tex]f(6.7) = 7[/tex]
Also, Take x = 6.8
[tex]f(6.8) = round(6.8)[/tex]
[tex]f(6.8) = 7[/tex]
Notice that the above values of x give the same resulting value of f(x).
If you also take x = 7.4
[tex]f(7.4) = round(7.4)[/tex]
[tex]f(7.4) = 7[/tex]
This also gives the same value as the (2) illustration previously used
With these illustrations, we've seen that f(x) has the tendency to have more than one values for different values of x.
Hence:
The function is not one-to-one

StartFraction B R Over R D EndFraction = StartFraction B S Over S C EndFraction If the ratio of BR to BD is Two-thirds, then it is possible that BS = 6 and BC = 3. (BR)(SC) = (RD)(BS) StartFraction B R Over R S EndFraction = StartFraction B S Over S C EndFraction
Answers
Answer:
The correct options are;
1) ΔBCD is similar to ΔBSR
2) BR/RD = BS/SC
3) (BR)(SC) = (RD)(BS)
Step-by-step explanation:
1) Given that RS is parallel to DC, we have;
∠BDC = ∠BRS (Angles on the same side of transversal)
Similarly;
∠BCD = ∠BSR (Angles on the same side of transversal)
∠CBD = ∠CBD = (Reflexive property)
Therefore;
ΔBCD ~ ΔBSR Angle, Angle Angle (AAA) rule of congruency
2) Whereby ΔBCD ~ ΔBSR, we therefore have;
BC/BS = BD/BR → (BS + SC)/BS = (BR + RD)/BR = 1 + SC/BS = RD/BR + 1
1 + SC/BS = 1 + RD/BR = SC/BS = 1 + BR/RD - 1
SC/BS = RD/BR
Inverting both sides
BR/RD = BS/SC
3) From BR/RD = BS/SC the above we have by cross multiplication;
BR/RD = BS/SC gives;
BR × SC = RD × BR → (BR)(SC) = (RD)(BR).
This question is related to properties of similar figures. Therefore, the three statements that are correct are:
ΔBCD is similar to ΔBSR [tex]\frac{BR}{RD}[/tex] = [tex]\frac{BS}{SC}[/tex] (BR)(SC) = (RD)(BS)Two or more figures or shapes are said to be similar if they have all properties in common. This implies angles, orientation and parallel/ perpendicular sides etc.
Comparing the properties of the sketch for the question, the required statements that are correct are:
a. ΔBCD is similar to ΔBSR
b. [tex]\frac{BR}{RD}[/tex] = [tex]\frac{BS}{SC}[/tex]
c. (BR)(SC) = (RD)(BS)

Which expression is equivalent to 18 - 7?
Apex
Answers
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let me help out.
To get an expression that is equivalent to 18 - 7, you will have to know the value of 18-7 first. This will be:
= 18 - 7
= 11
Since we know that 18-7 = 11, then from the options that you're given, you'll find the one that is also equal to 12 which will be the answer.
For example, let's say you're given the options of a. 20 - 6 and b. 3 + 19 - 11.
20 - 6 = 14. This means that it isn't an equivalent of 18-7.
3+19-11 = 11. So, this is an equivalent of 18-7.

Snow is accumulating on mrs. Garcias driveway at a rate of 3/4 of an inch per hour. If there were already 3 inches of snow on her driveway when she woke up at 6:00 in the morning, how many inches of snow were on the driveway when she started shoveling 90 minutes later?
Answers
Answer:
4.125 inches.
Step-by-step explanation:
Based on the information provided we see that she took 90 minutes before shovelling which is 1 hour and 30 minutes or 1 1/2 hours (1.5 hours). Since we also know that the snow has been accumulating at a rate of 3/4 (0.75) inch per hour then we simply multiply these two values together to find out how much snow has accumulated.
0.75 * 1.5 = 1.125 inches
Now we can add this amount to the initial amount at 6:00 in the morning to find how many inches of snow were on the driveway when she started shovelling
3 + 1.125 = 4.125 inches.
a) A shopkeeper sold a mobile set for Rs 9,600 and made a loss of 5%. For what price should he sell it to gain 10 percent
Answers
Answer:
Rs 11115.5
Step-by-step explanation:
Selling price =Rs 9600
%loss = cost price - selling price. ×100
cost price.
5 = cost price - Rs 9600 ×100
cost price
Let Cp = cost price
5Cp = 100Cp - Rs 960000
5Cp - 100Cp = - Rs 960000
-95Cp = -Rs 960000
Cp = 960000/95
Cp = Rs 10105
%profit = Sp - Cp ×100
Cp
10 = Sp - 10105 ×100
10105
(10105×10)/100 = Sp - 10105
1010.5 = Sp -10105
Sp = 1010.5 +10105
Sp = Rs 11115.5
Answer:
Rs 10600
Step-by-step explanation:
we can use cross multiplication
95 = 9600
105 = x
95x = 1008000
x=1008000/95
x = 10610.5

Rachel and her friends are making necklaces out of beads and straws. They plan to use 12 beads and 5 straws for each necklace. They have a jar of beads that contains a total of 2,700 beads. How many necklaces can they make? Write an equation to solve the problem. ÷ =
Answers
Answer:
225 necklaces.
Step-by-step explanation:
Assuming that they have the necessary amount of straws to match the beads then we can use the following simple equation to solve this problem.
t = b/12 ... where t is the total amount of necklaces and b is the number of beads you have
t = 2700 / 12
225 necklaces.
For 225 necklaces you would also need 1125 straws since each necklace requires 5 straws to be fully made. Therefore if you have this amount you should not run into any problems.
Resuelve las siguientes ecuaciones y luego verifica
A-)3x +1=7
B-)2a-2=1+3a
Answers
Answer:
A) x=2
B) a=-3
Step-by-step explanation:
La primera ecuación dada es,
A) 3x + 1 = 7
Reste 1 de ambos lados, tenemos
3x +1-1=7-1
[tex]\Rightarrow 3x=6[/tex]
Dividir por 3 (ya que 3 es un número distinto de cero) de ambos lados, tenemos
[tex]\frac{3x}{3}=\frac {6}{3}[/tex]
[tex]\Rightarrow x=2[/tex]
Ahora, compruebe si x = 2 es la solución correcta o no.
El lado izquierdo de la ecuación dada es 3x + 1.
Ponga x = 2, tenemos
[tex]3\times2+1=7[/tex]
Que es igual al lado derecho de la ecuación dada.
Por tanto, x = 2 es la solución correcta.
La segunda ecuación es
B) 2a-2=1+3a
Reste 3a de ambos lados, tenemos
2a-2-3a=1+3a-3a
[tex]\Rightarrow -a-2=1[/tex]
Suma 2 de ambos lados, tenemos
-a-2+2=1+2
[tex]\Rightarrow -a=3[/tex]
Multiplica por -1 (como -1 es un número distinto de cero) de ambos lados, tenemos
[tex]-a\times (-1)=3\times(-1)[/tex]
[tex]\Rightarrow a=-3[/tex]
Ahora, verifique si a = -3 es la solución correcta o no
El lado izquierdo de la ecuación dada es 2a-2.
Ponga a = -3, tenemos
[tex]2\times(-3)-2=-8[/tex]
El lado derecho de la ecuación dada es 1 + 3a.
Ponga a = -3, tenemos
[tex]1+3\times(-3)=-8[/tex].
Aquí, al poner a = -3, el valor del lado izquierdo es igual al valor del lado derecho.
Por tanto, a = -3 es la solución correcta.
