-6=b/18
Answer:
b=-108
Step-by-step explanation:
To solve this equation for b, you simply multiply each side by 18. The reason you do this is to isolate the b.
[tex]-6=\frac{b}{18}[/tex]
[tex]18(-6)=(\frac{b}{18} )(18)[/tex]
[tex]-108=b[/tex]
The ratio of two complementary angles is 7:2. What is the measure, in degrees, of the larger angle?
Answer:
70 degrees
Step-by-step explanation:
Complementary angles sum up to 90.
To find the larger angle, you find the total of the values in the ratio, divide the larger value of the ratio by the total and multiply it by 90.
(7/7+2)×90=7/9×90
=7×10
=70
OR
Write an equation:
7x+2x=90
9x=90
x=10
Then multiply x by the larger value.
7x=7 (10)=70
how to solve 4x + 7 = -2x + 19
subtract 7 from both sides
4x = -2x + 12
add 2x to both sides
6x = 12
divide both sides by 6
x = 2

Note: Since you missed to add the figure. So, after a little research I am kind of able to find the figure and hence, assuming it as a reference. Hence, I am attaching the figure and solution of that figure is also visible in the same figure. Please check the attached figure (a)
Answer:
Segment B'D' will be parallel to segment BD and will be shorter than segment BD. Please see the attached figure (a) for better understanding.
Step-by-step explanation:
As we know that there are certain rules when a quadrilateral is dilated by a certain scale centered around a certain point.
So,
Let suppose P(a, b) is the point.
The dilation rule by a scale factor of 1 over 3 or (1/3) centered around (1, 2) is
P(a, b) → [tex]P(\frac{x+2}{3}, \frac{y+4}{3})[/tex]
Hence,
A(1, 2) → A'(1, 2)
B(2, 3) → B'(4/3, 7/3)
C(4, 2) → C'(2, 2)
D(2, 1) → D'(4/3, 5/3)
The attached figure show that if we draw the all these points in the coordinate plan i.e. A(1, 2), B(2, 3), C(4, 2), D(2, 1) and A'(1, 2), B'(4/3, 7/3), C'(2, 2), D'(4/3, 5/3), we can determine that Segment B'D' will be parallel to segment BD and will be shorter than segment BD.

In the 2006 Winter Olympics, Sweden won 3 medals more than China. Germany
secured one more than twice the number of medals bagged by sweden. It 54
medals were won in all, how many medals did Germany secure?
Final answer:
To find out how many medals Germany secured in the 2006 Winter Olympics, we denote the number of medals Sweden won as S and create an equation based on the problem's description. Solving for S, we find that Sweden won 14 medals, so Germany, with one more than twice the number of Sweden's medals, secured 29 medals in total.
Explanation:
The question requires us to solve a problem that involves understanding and creating equations based on the given information.
Let's denote the number of medals Sweden won as S. According to the problem, China won S - 3 medals, and Germany won 2S + 1 medals. The total number of medals won by all three countries is 54, so the equation to represent this information is:
S + (S - 3) + (2S + 1) = 54
By combining like terms, we get:
4S - 2 = 54
Now, we will solve for S:
4S = 56 ⇒ S = 14
Now that we know Sweden won 14 medals, we can determine the number of medals Germany secured, which is 2S + 1:
2(14) + 1 = 29
Therefore, Germany secured 29 medals in the 2006 Winter Olympics.
find the domain of the function below if the domain is {-1,0,2} f(x)=x^2 -2x+3
Answer:
The Range is {3, 6}.
Step-by-step explanation:
The correct question is
Find the range of the function below if the domain is {-1,0,2} f(x)=x^2 -2x+3
we know that
The domain represents all possible values of x.
The range represents all possible values of f(x)
Substitute all of the possible x-values (domain) into the formula to find all possible f(x) values (the range).
For x=-1
[tex]f(-1)= (-1)^{2} - 2(-1) + 3[/tex]
[tex]f(-1)=1+2+ 3[/tex]
[tex]f(-1)=6[/tex]
For x=0
[tex]f(0)= (0)^{2} - 2(0) + 3[/tex]
[tex]f(0)=0-0+ 3[/tex]
[tex]f(0)=3[/tex]
For x=2
[tex]f(2)= (2)^{2} - 2(2) + 3[/tex]
[tex]f(2)=4-4+ 3[/tex]
[tex]f(2)=3[/tex]
therefore
The Range is {3, 6}.

Bryson’s dad is 38 years old. If this is four years less than three times Bryson’s age, how old is Bryson?
Answer:
Bryson’s age is 14 years
Step-by-step explanation:
Let
x ----> Bryson’s age
we know that
Bryson’s age multiplied by 3 minus 4 must be equal to 38
so
The linear equation that represent this situation is
[tex]3x-4=38[/tex]
solve for x
Adds 4 both sides
[tex]3x=38+4[/tex]
[tex]3x=42[/tex]
Divide by 3 both sides
[tex]x=14[/tex]
therefore
Bryson’s age is 14 years
A worker at a snack stand opened a new box of cups. The first day he used 30 cups , the second day the worker used 15 percent of the remaining cups. A total of 90 cups were used the second day.what was the original amount of cups in the box before any were used?
plz help asap will give u brainliest :)
Answer:
Step-by-step explanation:
the first day he used 30 cups
the second day he used 15% of the remaining cups...a total of 90 cups were used on second day.
so 15%of the remaining cups = 90.....so if u let x be the total cups, then the remaining cups would be x - 30
15% of (x - 30) = 90.....turn ur percent to a decimal..." of " means multiply
0.15(x - 30) = 90
0.15x - 4.5 = 90
0.15x = 90 + 4.5
0.15x = 94.5
x = 94.5 / 0.15
x = 630 total cups <==
lets check..
start with 630 cups....used 30 the first day....leaving u with 600 cups....15% of the remaining cups = 90.....so 15% of 600 = 90....lets check it
15%of 600 = 0.15(600) = 90...yep, thats correct....there were 630 cups in the new un-opened box
Answer:
630
Explanation:
15% * number of remaining cups = 90
15% * (x-30) = 90
0.15(x-30) = 90
0.15x - 4.5 = 90
0.15x = 94.5
x = 630

Find the sum.
7x + 15x=
Answer:
7x + 15x= 21x
Step-by-step explanation:
7x + 15x
= (7 + 15)x
= 22x
Answer: 22x
Step-by-step explanation: +7x and +15x are called terms and the numbers in front of the variables, +7 and +15 are called coefficients.
Because the variables, x and x, are identical, the two terms in this problem are called like terms. Like terms can be added together by simply adding their coefficients. So in this problem, since 7 + 15 is 22, 7x + 15x is simply 22x.

Step-by-step explanation:
Given,
Dividend = [tex](x^5+1)[/tex]
Divisor = [tex](x+1)[/tex]
Now According to the rule of Division.
Step 1: At first dividend is [tex](x^5+1)[/tex] and Divisor is [tex](x+1)[/tex] when it is divided for the first time the quotient will be [tex]x^4[/tex] and remainder will be [tex]-x^4+1[/tex]
Step: 2 Now the remainder of step 1 will be new dividend which is [tex]-x^4+1[/tex] and Divisor is [tex](x+1)[/tex] so when it is divided the quotient will be [tex]x^4-x^3[/tex] and remainder will be [tex]x^3+1[/tex]
Step: 3 Now the remainder of step 2 will be new dividend which is [tex]x^3+1[/tex] and Divisor is [tex](x+1)[/tex] when it is divided the quotient will be [tex]x^4-x^3+x^2[/tex] and remainder will be [tex]-x^2+1[/tex]
Step: 4 Now the remainder of step 3 will be new dividend which is [tex]-x^2+1[/tex] and Divisor is [tex](x+1)[/tex] when it is divided the quotient will be [tex]x^4-x^3+x^2-x[/tex] and remainder will be [tex]x+1[/tex]
Step: 5 Now the remainder of step 4 will be new dividend which is [tex]x+1[/tex] and Divisor is [tex](x+1)[/tex] when it is divided the quotient will be [tex]x^4-x^3+x^2-x+1[/tex] and remainder will be 0.
Hence When the polynomial [tex](x^5+1)[/tex] is divided by [tex](x+1)[/tex] the answer or quotient will be equal to [tex]x^4-x^3+x^2-x+1[/tex] and remainder will be 0.

Determine the equation for the parabola graphed below.
y =
x2 +
x +
Answer:
[tex]\large\boxed{y=\dfrac{1}{2}x^2-2x+1}[/tex]
Step-by-step explanation:
The vertex form of an equation of a parabola:
[tex]y=a(x-h)^2+k[/tex]
(h, k) - vertex
a - leading coefficient in equation y = ax² + bx + c
From the grap we can read coordinates of the vertex (2, -1) and y-intercept (0, 1).
Therefore h = 2, k = -1
Put the values of h, k and coordinates of the y-intercept to the equation of parabola:
[tex]1=a(0-2)^2-1[/tex] add 1 to both sides
[tex]1+1=a(2)^2-1+1[/tex]
[tex]2=4a[/tex] divide both sides by 4
[tex]\dfrac{2}{4}=\dfrac{4a}{4}\\\\\dfrac{1}{2}=a\to a=\dfrac{1}{2}[/tex]
Therefore we have the equation:
[tex]y=\dfrac{1}{2}(x-2)^2-1[/tex]
Convert to the standard form:
[tex]y=\dfrac{1}{2}(x-2)^2-1[/tex] use (a - b)² = a² - 2ab + b²
[tex]y=\dfrac{1}{2}(x^2-2(x)(2)+2^2)-1[/tex]
[tex]y=\dfrac{1}{2}(x^2-4x+4)-1[/tex] use the distributive property
[tex]y=\dfrac{1}{2}x^2-\dfrac{1}{2}\cdot4x+\dfrac{1}{2}\cdot4-1[/tex]
[tex]y=\dfrac{1}{2}x^2-2x+2-1[/tex] combine like terms
[tex]y=\dfrac{1}{2}x^2-2x+1[/tex]

A landscaper installed a circular sprinkler system using 50.25 feet of copper tubing to create the circle. To the nearest whole foot, what is the diameter of the circular sprinkler
Answer:
4 foot
Step-by-step explanation:
√50.25 / 3.1416 = 4
The diameter of the circular sprinkler is 16 feet.
Explanation:To find the diameter of the circular sprinkler, we can use the formula for the circumference of a circle: C = πd, where C is the circumference and d is the diameter. In this case, we are given the length of the copper tubing used, which is equal to the circumference. So we can rearrange the formula to solve for the diameter: d = C/π. Plugging in the given values, we have d = 50.25/π. Using the value of π as approximately 3.14, we can calculate the diameter to the nearest whole foot.
d ≈ 50.25/3.14 ≈ 16.01 feet
Therefore, the diameter of the circular sprinkler to the nearest whole foot is 16 feet.

Aaron spent $20.50 altogether at the carnival and the number of games he played is twice the number of rides he went on. Determine the number of games Aaron played and the number of rides Aaron went on.
Answer:
Step-by-step explanation:
2.75g + 4.75r = 20.50
g = 2r
2.75(2r) + 4.75r = 20.50

r = 2 <==== Aaron went on 2 rides
g = 2r
g = 2(2)
g = 4 <==== Aaron played 4 games
check...
2.75g + 4.75r = 20.50
2.75(4) + 4.75(2) = 20.50
11 + 9.5 = 20.50
