Step-by-step explanation:
Jasmine surveyed the people at a local playground. She found that 33 out of 55 people brought water bottles. On Wednesday, Jasmine returns to the park and finds that 1212 people brought water bottles. About how many people do you expect were at the park on Wednesday? Enter the number of people at the park on Wednesday.
Answer:
2,020 people were at the park.
Step-by-step explanation:
33/55 = 1212/x

Sensei Umeh’s ""Active Hands"" karate program grew from 8 members to 15 last week. What is the percent of change?
Answer:
187.5% increase
Step-by-step explanation:
Percent change formula: [tex]\frac{x_{2}-x_{1}}{x_{1}}[/tex]
Initially, the program had 8 members and ended with 15 so [tex]\frac{15-8}{8}=\frac{7}{8}=0.875=87.5[/tex]

factor completely x^2-4
Answer:
(x + 2) (x - 2)
Step-by-step explanation:
Given the quadratic expression, x² - 4:
Use the Difference of squares factoring formula:
u² - v² = (u + v)(u - v)
Determine what are possible factors that could have a product of -4:
Since -2 × 2 = -4, these can be used as factors.
Therefore, the factors of the quadratic expression, x² - 4 are:

Jolene is creating a model of a pyramid. The model created will need to be scaled up from the blueprint. triangle ACB, point D is on segment AC between points A and C, point E is on segment BC between points B and C If segments DE and AB are parallel, which of the following expressions will help Jolene determine the length of segment AC? AC equals CB times CD all over CE AC = AB AC equals CB times AC all over CE AC = BC
Answer:
AC equals CB times CD all over CE
The lengths of the sides of the scaled drawing can be determined from the
relation between similar triangles.
The expression that will help Jolene determine the length segment AC is the option;
[tex]\displaystyle \underline{CD= \frac{CB\cdot CD}{CE}}[/tex]Reasons:
The given parameters are;
The figure Jolene is trying to create = A scaled up blue print
Given that in ΔACB and ΔABC, we have;
DE and AB are parallel
Therefore;
∠CED ≅ ∠CBA by corresponding angles
∠CDE ≅ ∠CAB by corresponding angles
∠C ≅ ∠C by reflexive properties
ΔCDE ~ ΔACB by Angle-Angle similarity postulate
Therefore, by similar triangles, and triangle proportionality, we have;
[tex]\displaystyle \frac{AC}{CD} = \mathbf{\frac{CB}{CE}}[/tex]
Therefore;
[tex]\displaystyle CD= \mathbf{ \frac{CB\cdot CD}{CE}}[/tex]
Therefore, if segments DE and AB are parallel, the expression that will help Jolene determine the length segment AC is; [tex]\displaystyle CD= \frac{CB\cdot CD}{CE}[/tex]

Solve the inequality- 5/2(3x+4)<6-3x. Show your work.
Answer:
x < -8/21
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex](\frac{5}{2} * 3x) + (\frac{5}{2} * 4) < -3x + 6[/tex] [tex]\frac{15}{2}x + 10 < -3x + 6[/tex]Step 2: Add 3x to both sides.
[tex]\frac{15}{2}x + 10 + 3x < -3x + 6 + 3x[/tex] [tex]\frac{21}{2}x + 10 < 6[/tex]Step 3: Subtract 10 from both sides.
[tex]\frac{21}{2}x + 10 - 10 < 6 - 10[/tex] [tex]\frac{21}{2}x < -4[/tex]Step 4: Multiply both sides by 2/21.
[tex]\frac{21}{2}x * \frac{2}{21} < -4 * \frac{2}{21}[/tex] [tex]x < -\frac{8}{21}[/tex]Therefore, the answer is x < -8/21.

Answer:
Slope = -4
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes, which means that multiplying their slopes result in a product of -1. Given the equation, x - 4y = - 12:
Transform the equation into its slope-intercept form, y = mx + b:
x - 4y = - 12
x - x - 4y = - x - 12
-4y = -x - 12
Divide both sides by -4:
[tex]\frac{-4y}{-4} = \frac{-x - 12}{-4}[/tex]
y = ¼x + 3 ⇒ (This is the slope-intercept form of the given standard equation, x - 4y = - 12).
Since the slope of the given equation is ¼, then it means that its negative reciprocal must be - 4:
(¼) (-4) = -1
Therefore, the slope of the line perpendicular to x - 4y = - 12 is - 4.
Solve to find X. 1/5(x - 2) = 1/10 (x + 6)
Answer:
x = 10
Step-by-step explanation:
First, distribute:
[tex]\frac{1}{5} x - \frac{2}{5} =\frac{1}{10} x+\frac{6}{10}[/tex]
Next, subtract [tex]\frac{1}{5}x[/tex] from both sides:
[tex]-\frac{2}{5} = \frac{1}{10} x -\frac{1}{5} x+\frac{6}{10}[/tex]
(multiply [tex]\frac{1}{5}x[/tex] by 2 to get common denominator, [tex]\frac{2}{10} x[/tex] )
[tex]-\frac{2}{5} =-\frac{1}{10}x +\frac{6}{10}[/tex]
Next, subtract [tex]\frac{6}{10}[/tex] from both sides:
[tex]-\frac{2}{5} -\frac{6}{10} =-\frac{1}{10} x[/tex]
(multiply [tex]\frac{2}{5}[/tex] by 2 to get common denominator, [tex]\frac{4}{10}[/tex] )
[tex]-\frac{10}{10} =-\frac{1}{10} x[/tex] ⇒ [tex]-1=-\frac{1}{10} x[/tex]
Next, multiply both sides by 10:
[tex]-10=-x[/tex]
FInally, divide both sides by -1:
x = 10
Answer:
Step-by-step explanation:
1/5(x-2) =1/10(x+6)
1/5x-2 = 1/10x+0.6
1/5x+1/10x= 0.6-2
0.2x+0.1x= -1.4
0.3x= -1.4
x= -4.67
x= -4.7
x= -5

Answer: The measurement of ∠EFG is equal to 70°.
Step-by-step explanation:
Two interior angles who are always opposite to an exterior angle sums to that exterior angle. So we would start as the following:
(6x - 10) + 38 = 7x + 18
In order to find m∠EFG, we must first isolate x. In order to do that, we first add like terms together on both sides.
(6x - 10) + 38 = 7x + 18
6x + 28 = 7x + 18
We then substract 18 on both sides.
6x + 10 = 7x
We finally substract 6x from both sides in order to have the value of x.
x = 10
Now that we know the value of x, we substitute it in our the equation in order to find m∠EFG.
m∠EFG = 6x + 10
m∠EFG = 6(10) + 10
m∠EFG = 60 + 10
m∠EFG = 70
Answer:
50°
Step-by-step explanation:
( 7x + 18 )° = ( 6x - 10 )° + 38°
7x + 18 = 6x - 10 + 38
7x - 6x = 28 - 18
x = 10
m∠EFG = 6(10) - 10
m∠EFG = 50°

Given the function h(x) = x2 – 7x + 6, determine the average rate of change of
the function over the interval 3 x < 7.
Step-by-step explanation:
the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
so,
(h(7) - (h(3)) / (7 - 3)
h(7) = 7² - 7×7 + 6 = 49 - 49 + 6 = 6
h(3) = 3² - 7×3 + 6 = 9 - 21 + 6 = -6
7 - 3 = 4
(6 - -6)/4 = 12/4 = 3
the average change rate in that interval is 3 (or fully 3/1).
