Answer:
7 R 95
for this case, how many times does 99 go into 788? 0, because you must convert 78 to the tens place.
78 - 0 = 78
Drop the 8 from the zeros place.
How many times does 99 go into 788? 7(693)
788 - 693 = 95

A new hospital tracked the number of births during its first 6 months of operation, as shown in the table. A 2-column table with 6 rows. The first column is labeled month with entries 1, 2, 3, 4, 5, 6. The second column is labeled number of births with entries 137, 110, 93, 70, 65, 77. Find a quadratic function that models the data. Round numerical values to the nearest whole number. F(x) = x2 x Use the function to predict the number of births for month 8. There will be about births.
The hospital uses the quadratic model to predict the number of births
The equation of the quadratic model is f(x) = 4 x^2 -43 x +178, and the number of births for month 8 is 90
How to determine the quadratic modelTo determine the quadratic model, the make use of a graphing calculator, that has the following calculation summary
a = 4.339 b = -43.461 c = 178.3A quadratic model is represented as:
[tex]y= ax^2 + bx + c[/tex]
So, we have:
[tex]y = 4.339 x^2 -43.461 x +178.3[/tex]
Approximate
[tex]y = 4 x^2 -43 x +178[/tex]
Rewrite as:
[tex]f(x) = 4 x^2 -43 x +178[/tex]
At the 8th month, we have x = 8.
So, the function becomes
[tex]f(8) = 4 * 8^2 -43 *8 +178[/tex]
[tex]f(8) = 90[/tex]
Hence, the number of births for month 8 is 90

Write an equation that relates the time, t, it takes to travel a given distance, d.
The equation that relates the time, t, it takes to travel a given distance, d is d = rt
What is Speed?This is a scalar quantity and can be defined as the magnitude of the rate of change of its position with time.
d = rt
where d is distance, r is speed or rate, t is time.
We can calculate the time by dividing the distance with the rate (speed).
t = d/r

A ferris wheel can accommodate 70 people in 20 minutes. How many people could ride the ferris wheel in 5 hours? What was that rate per hour?
Answer:
210 is the rate per hour and 1,050 people in 5 hours
Step-by-step explanation:
Answer:
Step-by-step explanation:
You need to get answer to people per hour first. 70 people could ride the ferris wheel in 20 minutes. 20 minutes is 1/3 of 60 minutes, which is an hour. So you multiply both the time and the amount of people by 3. 70 times 3 is 210. This is the amount of people that could ride the ferris wheel in 1 hour. Then, we need to multiply this number by 5, because we need the amount of people that could ride the ferris wheel in 5 hours, not 1 hour. So 210 times 5 is 1,050. 1,050 people could ride the ferris wheel in 5 hours.
Next, we need to find the rate per hour. You already have the answer to that though. It is the amount of people that could ride the ferris wheel, so your previous number: 210. Your rate would be 210 people per hour could ride the ferris wheel.

Answer:
The function is
The remainder when f(x) is divided by x−2 is 23
To find:
The value of k.
Solution:
According to the remainder theorem, if a polynomial P(x) is divided by (x-c), then the remainder is P(c).
It is given that, the remainder when f(x) is divided by x−2 is 23. By using the remainder or theorem, we get
Put x=2, to find the value of f(2)
Using (i) and (ii), we get
Therefore, the value of k is 8.

f(x) - 2x³ + kx - 4 and the remainder when f(x) is divided by x + 2 is -18. then k is 15.
What is Remainder theorem?The remainder theorem states that when a polynomial p(x) is divided by (x - a), then the remainder = f(a)
f(x)=2x³ + kx - 4
x+2=0
x=-2
By the remainder theorem, the remainder when dividing by x-a is f(a)
f(-2)=2(-2)³+k(-2)-4
=-2(-8)-2k-4
=16-2k-4
The remainder is -18.
So, 16-2k-4=-18
12-2k=-18
-2k=-18-12
-2k=-30
k=15
Hence the value of k is 15.

What is the equation of this graphed line?
Enter your answer in slope-intercept form (y = mx + b) in the
box
Answer:
[tex]y = - \frac{9}{8} x + 7[/tex]
Step-by-step explanation:
[tex]m = \frac{ - 2 - 7}{8 - 0} = \frac{ - 9}{8} [/tex]
Since this line passes through (0,7), then this point satisfies the equation of the line;
[tex]y = \frac{ - 9}{8} x + b[/tex]
[tex]7 = \frac{ - 9}{8} (0) + b[/tex]
[tex]7 = b[/tex]
[tex]b = 7[/tex]
Hey there!
We are given 2 points that the line passes through, so we can easily determine the slope of the line:
[tex]\bold{\displaystyle\frac{y2-y1}{x2-x1} }[/tex]
[tex]\bold{\displaystyle\frac{-2-7}{8-0}=\frac{-9}{8} }[/tex]
So now we have the slope.
However, we also need to find the y-intercept (we are actually given the y-intercept, (0,7) or just 7)
Hence, the equation is
[tex]\boxed{\boxed{\bold{y=-\frac{9}{8} x+7}}}[/tex]

Lisa supplies costumes to a number of theater companies and recently lent out a number of different hats. ski hats 4 berets 1 turbans 5 Considering this data, how many of the next 18 hats requested from Lisa's inventory should you expect to be turbans?
The total number ot turbans that Lisa's inventory should have 9 turbans in the next 18 hats when requested, under the condition that recently lent out a number of different hats. ski hats 4 berets 1 turban.
The evaluated probability of turbans in Lisa's inventory is 5/10 or 1/2. This projects that out of every 10 hats in Lisa's inventory, 5 are turbans.
To evaluate the expected number of turbans in the next 18 hats taken from Lisa's inventory, we can apply the formula:
Expected number of turbans = Probability of turbans × Total number of hats requested
Staging the values
The turbans that are expected
= (1/2) × 18

Shen runs 7 miles in 50 minutes. At the same rate, how many miles would he run in 75 minutes?
Answer:
(7 miles)/(50 minutes) = (x miles)/(75 minutes)
7/50 = x/75
7*75 = 50x
525 = 50x
50x = 525
x = 525/50
x = 10.5

The midpoint of AB is M(4,4). If the coordinates of A are (2, 1), what are the
coordinates of B?
Answer:
(6, 7)
Step-by-step explanation:
Hope this helps.
The midpoint of the line segment AB is M. Then the coordinate of the point B will be (6, 7).
What is the mid-point of the line segment?Let AB be the line segment and C be the mid-point of line segment AB. Let the coordinate of point A (x₁, y₁), the coordinate of point B (x₂, y₂), and the coordinate of the mid-point (x, y).
Then the coordinate of the mid-point of the line segment is given as,
(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]
The midpoint of AB is M(4,4). If the coordinates of A are (2, 1). Then the coordinate of the point B will be given as,
(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]
(4, 4) = [(2 + x₂) / 2, (1 + y₂) / 2]
Compare the abscissa, then we have
(2 + x₂) / 2 = 4
(2 + x₂) = 8
x₂ = 8 - 2
x₂ = 6
Compare the ordinate, then we have
(1 + y₂) / 2 = 4
1 + y₂ = 8
y₂ = 8 - 1
y₂ = 7
The midpoint of the line segment AB is M. Then the coordinate of the point B will be (6, 7).

The ratio of boys to girls in our class is 4 to 5. If
there are 8 girls, then how many total students are
in the class?
Answer:
6.4/6
Step-by-step explanation:
Since
4 : 5 = X : 8
Then we know
4/5 = X/8
Multiplying both sides by 8 cancels on the right
8 × (4/5) = (X/8) × 8
8 × (4/5) = X
Then solving for X
X = 8 × (4/5)
X = 6.4

Step-by-step explanation:
Right Triangles
The right triangles are identified because they have an internal angle of 90°. The basic trigonometric ratios can be used to find angles and side lengths as needed.
We have a right triangle with the following characteristics:
The hypotenuse is 13 units long
The indicated angle is opposite to the leg of 10 units long.
When we know the length of the opposite side, we use the sine ratio. Let's call θ to the required angle:
[tex]\displaystyle \sin\theta=\frac{\text{opposite side}}{\text{hypotenuse}}[/tex]
[tex]\displaystyle \sin\theta=\frac{10}{13}[/tex]
Using a calculator set in mode degrees, the angle is:
[tex]\theta=\sin^{-1}\frac{10}{13}[/tex]
[tex]\theta\approx 50.3^\circ[/tex]
First choice: 52° is not correct because is not a good approximation to 50.3°
