I think of a number ÷ 4 and add 11 result is 19 find the number
Answer:
32
Step-by-step explanation:
work backwards, 19-11=8 then x 4 makes 32.
Answer:
32
Step-by-step explanation:
Let the number be 'x'
[tex]\dfrac{x}{4}+11=19[/tex]
Subtract 11 from both sides
[tex]\dfrac{x}{4}=19 - 11\\\\\dfrac{x}{4}=8\\[/tex]
Multiply both sides by 4
x = 8*4
x = 32
Aliza plays basketball every Tuesday and
Thursday. She practices piano every other
day. If June started on a Monday, and if
Aliza played piano that day, on how many
days did she both play basketball and practice piano in June (which has 30 days)?
A. 2 days
B. 4 days
C. 5 days
D. 7 days
Answer:
4 days
Step-by-step explanation:
June starts on Monday
for 30days we have 4 weeks starting from Monday to Sunday and extra 2 days which are Monday and Tuesday
so we have 5 mondays and tuesdays
4 wed, thu, fri, sat, sun
Aliza played piano on june1 monday
So aliza played basketball on 5 tues + 4 thurs = 9 days
for calculating both basketball and paino
piano day should be on tuesday or thursday
from the below picture u can see pink dots are piano days
and yellow circles are both piano and basketball days
so on alternate weeks they are coinciding
so there are 4 days

a poultry farmer sold 1/2 of his eggs and ate 1/3 of the remainder if he has 400 left how many eggs had he originally
Answer:
2400 eggs
Step-by-step explanation:
1. To find out how many eggs the poultry farmer had originally, we have to reverse the steps of him selling and eating this eggs.
This means to basically multiply 400 by the reciprocal (inverse) of 1/2 and 1/3.2. (Solving)
[tex](2)(3)(400)[/tex] [tex](6)(400)[/tex] [tex]2400[/tex]Therefore, he had 2400 eggs originally.
14. The supervisors of a rural county are interested in the proportion of property owners who
support the construction of a new high school for the area. Rather than contact all 7,000 of
the owners, the supervisors decide to take a random sample of 300.
(a) During each interview, the supervisor's representative asks, “Do you support the building
of a new high school for the area?” For this sample, 58% of the respondents said yes. If
the representative took a second random sample of 300 property owners, would this
second sample proportion of those who support building a new high school be exactly the
same as that found in the first sample?
(b) If the representative has increased the sample size to 600 owners, what effect would this
have on the estimated proportion of owners who would support building the high school?

Need to know the slope and the y intercept
Answer: Slope (M) = 7.5
Y-intercept (B) = 0
Step-by-step explanation:
For the slope, the first step is to find your "pretty points" (spots on the slope that hit the corner perfectly, like (0, 0) or (2, 15).
Now, make a triangle with the two points. Count the amount of squares on both. This will give you 3 and 4, but when taking the units into consideration, 15 and 2. The last step is to divide 15 and 2 which gives you 7.5. I would recommend writing both 15/2 and 7.5 but it's up to you.
The Y-intercept is just the spot where the Y is 0, or where the line touches the Y-axis. This is at the origin, where both X and Y are 0, so your Y-intercept is 0.

Thomas is a car salesman. He is paid a salary of $1600 per month plus $300 for each car that he sells. His salary can be modeled by the equation f(x) = 300x + 1600 where x is the number of cars sold. Graph this equation and give its domain and range.
Answer: D: 0, 1, 2, 3
R: ($1600, $1900, $2200, $2500,...)
Fyi: If you want answers to something I don't think threating to reporting people trying to help you is a good idea.
The Domain is {0, 1, 2, 3, 4} and Range is { 1600, 1900, 2200, 2500, 2800}.
What is Domain and Range?The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
Given:
He is paid a salary of $1600 per month plus $300 for each car that he sells.
and, His salary can be modeled by the equation f(x) = 300x + 1600
The Domain can be taken as
x= 0, 1, 2, 3, 4
and, the range is
f(0)= 1600
f(1)= 1900
f(2)= 2200
f(3)= 2500
f(4)= 2800

how do you do this??????????
Step-by-step explanation:
these are all isoceles triangles (2 sides are equal). that also means that the 2 angles at the end of the equal sides are equal.
so, the angle at F and H are both 65°.
the angle at J = 2×65 = 130°.
the angle at G = 2×(180 - 65 - 65) = 2×50 = 100°.
remember, the sum of all angles in a triangle is always 180°.
so many ways now to get y.
let's use the triangle GH and crossing point of diagonals (there is a right angle).
y = 180 - G/2 - 90 = 180 - 50 - 90 = 40°

Suppose the matrix R represents a railroad map between cities 1, 2, 3, 4, and 5.
How many different ways can you travel from city 1 to city 3 with exactly 1 connection
How many different ways can you travel from city 2 to city 5 with exactly one
connection?
Observing the given matrix we can say that:
1) The value is 4.
2) The value is 2.
So analyzing the different paths that can connect city 1 to city 3: The value is 4. It represents the number of one-stop routes between City 1 and City 3 that pass through City 2.
For the second statement we will have the value is 2. It is the number of direct routes from City 2 to City 5.

The length of the wire AC is 61 meters.
Pythagoras theorem is used to show the relationship between the sides of a right angled triangle.
We can find the length of wire AC using Pythagoras theorem:
AC² = 60² + (66 - 55)²
AC² = 60² + 11²
AC² = 3721
AC = 61 meter

Answer:
y = - [tex]\frac{4}{3}[/tex] x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line
m = [tex]\frac{-2-2}{3-0}[/tex] = [tex]\frac{-4}{3}[/tex] = - [tex]\frac{4}{3}[/tex]
The line crosses the y- axis at (0, 2 ) ⇒ c = 2
y = - [tex]\frac{4}{3}[/tex] x + 2 ← equation of line

The angles in a quadrilateral ABCD are A(3x+10), B(3x+4), C(x+50) and D(5x+8). Find the angles of the quadrilateral ABCD
please answer it fast..thank u
Answer:
A 8º
B 76º
C 74º
D 128º
Step-by-step explanation:
The sum of the angles is 360
(3x + 10) + (3x + 4) + (x + 50) + (5x + 8) = 360
Combine like terms
12x + 72 = 360
Subtract 72 from both sides
12x = 288
Divide both sides by 12
x = 24
--------------
A (3x+10) = 3*24 + 10 = 82
B (3x+4) = 3*24 + 4 = 76
C (x+50) = 24 + 50 = 74
D (5x+8) = 5*24 + 8 = 128
