Step-by-step explanation:
[tex]x: 77 = 7 : 11 \\x = \frac{77 \times 7}{11} = \\ = 49[/tex]
From the given equivalent ratio the value of x is the number 49.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
The given equivalent ratios are x:77=7:11
"Two or more ratios that reflect the same relation or comparison of numbers are known as equivalent ratios," according to the definition of the equivalent ratio. The idea of corresponding fractions is comparable. The term "proportion" also refers to the equivalence of two ratios.
Here, x/77 = 7/11
Multiply both the numerator and denominator of the ratio 7/11 by 7, we get 49/77
Now, x/77 = 49/77
So, x=49
Therefore, the value of x is 49.

A baker made 6 pounds of dough. He used 8 9 of the dough to make sandwich rolls. How much of the dough is left over?
Answer:
2/3 pound of dough is left
Step-by-step explanation:
Amount of dough available = 6 pounds
The amount used in making sandwich rolls = 8/9 of the total amount
= [tex]\frac{8}{9} \times6 = 5\frac{1}{3} pounds[/tex]
Therefore, amount of dough left over [tex]= 6- 5\frac{1}{3} = \frac{2}{3} \\[/tex]
Hence, 2/3 pounds of dough is left
Working alone, it takes Scott 16 minutes to inflate twenty balloons, Ashley can inflate the same twenty balloons in 15 minutes. Find how long it would take them if they worked together.
Answer:
7.74 minutes
Step-by-step explanation:
Scott's rate = 20 /16 = 1.25
Ashley's rate = 20 / 15 = 1.333
Combined rate = (1.25 + 1.3333) = 2.583333
Hence, time it will take to inflate 20 balloons :
Rate = number of balloons / time taken
2.583333 = 20 / time taken
Time taken = 20 / 2.583333
Time taken = 7.7419
It will take them approximately 7.7 minutes to inflate 20 balloons

Answer:
X=0,-2
Step-by-step explanation:
6 x ( x + 2 ) = 0 Divide each term in 6 x ( x + 2 ) = 0 by 6 . 6 x ( x + 2 ) 6 = 0 6 Cancel the common factor of 6 . x ( x + 2 ) = 0 6 Divide 0 by 6 . x ( x + 2 ) = 0 If any individual factor on the left side of the equation is equal to 0 , the entire expression will be equal to 0 . x = 0 x + 2 = 0 Set the first factor equal to 0 . x = 0 Set the next factor equal to 0 and solve.

complete the table, vertex, and max or min. <3
Answer:
Step-by-step explanation:
The function describes a parabola
for find the value of y we have to substitute the value of x in the function
x = -1
y = (-1-2)^2 =9
(-1;9)
x = 0
y = (0-2)^2 = 4
(0;4)
x = 1
y = (1-2)^2= 1
(1;1)
x = 2
y = (2-2)^2 = 0
(2;0)
x= 3
y = (3-2)^2 = 1
(3;1)
for the second part we can solve the square of the binomial
y = x^2 -4x + 4
direction of opening : we have to see if the term that multiply x^2 is positive or negative. In this case is not expessed so it is 1, a positive number.
So the direction of opening is : upwards
line of symmetry: -b/2a where b is the term that multiply x and a the term that multiply x^2
x = 4/2 = 2
vertex: the x - coordinate of the vertex is the same of the line of symmetry
so x = 2
for find the y - coordinate we have to substitute the value of x in the equation
y = 4 - 8 + 4 = 0
vertex = (2;0)
the parabola has an upwards direction of opening so it has a point of minimum that is the vertex itself.
minimum of 0

Given:
The triangle A'B'C' is the image of triangle ABC after a translation as shown in the given graph.
To find:
The rule of translation in ARROW NOTATION.
Solution:
The general rule for translation is:
[tex](x,y)\to (x+a,y+b)[/tex] ...(i)
Where, a and b are constants.
From the given graph it is clear that the coordinate of point A are (2,3) and coordinates of point A' are (4,-2).
Using (i), the image of A(2,3) is
[tex]A(2,3)\to A'(2+a,3+b)[/tex]
We have, A'(4,-2).
[tex]A'(2+a,3+b)=A'(4,-2)[/tex]
On comparing both sides, we get
[tex]2+a=4[/tex]
[tex]a=4-2[/tex]
[tex]a=2[/tex]
And,
[tex]3+b=-2[/tex]
[tex]b=-2-3[/tex]
[tex]b=-5[/tex]
Putting [tex]a=2[/tex] and [tex]b=-5[/tex] in (i), we get
[tex](x,y)\to (x+2,y+(-5))[/tex]
[tex](x,y)\to (x+2,y-5)[/tex]
Therefore, the rule in ARROW NOTATION for the given translation is [tex](x,y)\to (x+2,y-5)[/tex].

Answer:
C
Step-by-step explanation:
I did this by graphing the points on paper and then forming an equation from there. Another way is to do to slope equation. The slope equation is: [tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex], so you would just fill it in here. (4+4) (I did PLUS since subtracting a negative is adding a postive number). This equals 8. (0-2) is -2, so 8/-2 is -4x. For the y-intercept, it is already shown in the equation. This is 4 because if x is 0, then that is the y-intercept. So: y=-4x+4.

Roxanna invested $10,000 in an account that earns 8.5% interest that is
compounded monthly. Determine the amount of money in the account in
15 years. (Lesson 7-10b)
Answer:
$35,100
Step-by-step explanation:
Given data
Principal=$10000
Rate= 8.5%
Time = 15 years = 180 months
The expression for monthly compounded interest is
A=P(1+r/12)^t
substitute
A=10000(1+0.085/12)^180
A=10000(1+0.007)^180
A=10000(1.007)^180
A=10000*3.51
A=$35,100
Hence the balance is $35,100
A news channel on cable T.V. polled politicians on an issue to find out who agreed with a court decision. This is the graphic they used in their report.

What makes this graph misleading?
a.
The horizontal scale only shows three parties. It needs to show every party.
b.
The vertical scale is too broad. It needs to focus in on a narrower range.
c.
The horizontal scale exaggerates the differences between the parties.
d.
The vertical scale is too narrow. It needs to be a wider range, such as 0 to 100.
Please select the best answer from the choices provided
A
B
C
D
Answer: d. The vertical scale is too narrow. It needs to be a wider range, such as 0 to 100.
Step-by-step explanation:
The vertical scale is indeed too narrow. It needs to have a wider range that will enable a person who is looking at the graph, better compare the results shown because the magnitude of the number will be more apparent.
A range such as 0 to 100 would be ideal for this and would present the information in such a way that when a person looks at the graph, they understand the relative difference between the percentages who agreed with the court decision.
The circle below has center Z. Suppose that m XY = 122°. Find the following.
Answer:
m∠XZY = 122°
m∠XWY = 61°
Step-by-step explanation:
From the picture attached,
A circle has been given with center as Z.
∠XZY is a central angles subtended by the arc XY,
Therefore, measure of angle XZY will be equal to measure of ∠XZY.
m(∠XZY) = m(arc XY) = 122°
By another property of the circle,
"Inscribed angle measures the half of the central angle intercepted by the same arc."
Therefore, m∠XWY = [tex]\frac{1}{2}(\angle XZY)[/tex]
= [tex]\frac{1}{2}(122)[/tex]
= 61°

Find the slope of a line through the points (7, –8) and (–5, –7).
a -12
b-15/2
c -2/15
d -1/12
Answer:
D
Step-by-step explanation:
Slope = y2-y1/x2-x1
(7,-8) = (x1,y1)
(-5,-7) = (x2,y2)
Slope = (-7+8)/(-5-7)
= 1/-12
