Answer:
Calories from both fat and carbohydrates = 900 calories/day
Step-by-step explanation:
Number of calories eaten by Sandra per day = 2000 calories/day
Calories from fat = [tex]\frac{1}{4}[/tex] of the total number of calories per day
OR
Calories from fat = [tex]\frac{1}{4}\times 2000 = 500\ calories/day[/tex]
Calories from carbohydrates = [tex]\frac{1}{5}[/tex] of the total number of calories per day
OR
Calories from carbohydrates = [tex]\frac{1}{5}\times 2000 = 400\ calories/day[/tex]
To find the total number of calories from both fat and carbohydrates, we need to add the calories from fat and calories from carbohydrates as calculated above.
Calories from both fat and carbohydrates = Calories from fat + Calories from carbohydrates = 500 + 400 = 900 calories/day
At the annual dog show, Chantel noticed that there were three more Scotties than Schnauzers. She also
realized that the number of Wirehaired Terriers was five less than twice the number of Schnauzers. If there
were 78 dogs in all (counting Schnauzers, Scotties, and Wirehaired Terriers), how many Schnauzers were
there? Write and solve an equation.
9514 1404 393
Answer:
(s+3) +s +(2s-5) = 7820 SchnauzersStep-by-step explanation:
Each of the quantities is described in terms of the number of Schnauzers, and that is the number we are asked for. It is convenient to write an equation for the number of Schnauzers. We choose to use s for the variable representing that number.
s = # of Schnauzers
s+3 = # of Scotties, 3 more than the number of Schnauzers
2s-5 = # of Wire-haired Terriers, 5 less than twice the number of Schnauzers
The total number of dogs is then ...
(s+3) +(s) +(2s-5) = 78
4s -2 = 78 . . . . simplify
4s = 80 . . . . . . add 2
s = 20 . . . . . . . divide by 4
There were 20 Schnauzers at the dog show.

Answer:
y = -3x - 23
Step-by-step explanation:
When a transversal of the two lines is constructed, the alternate interior angles formed by the transversal are congruent. This means line m and n are parallel to each other so their slope will be the same.
Given:
line m: y = -3x + 8 <======= slope is -3
line n going through point (-4, -11) with same slope as line m:
y = mx + b
(-11) = -3(-4) + b
-11 = 12 + b
b = -23 <===== y-intercept of line n
Use the above slope and y-intercept to form equation of line n:
y = mx + b
y = -3x - 23

Complete question :
A zoologist is interested in whether climate affects how high kangaroos can jump. In a random sample of gray kangaroos from an Australian forest, he found the mean jump height was x¯=286 inches with a margin of error of 15 inches.
Construct a confidence interval for the mean jump height of gray kangaroos.
Answer:
(271, 301)
Step-by-step explanation:
Given that:
Mean (x¯) = 286
Margin of Error = 15 inches
The confidence interval :
(Mean - Margin of Error), (mean + margin of error)
(286 - 15), (286 + 15)
(271, 301)
Hence confidence interval equals : (271, 301)
Which graph represents a function?
Ay

ty
Answer: it would be the fourth one with the line going straight across the top
Step-by-step explanation: To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x.
If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.
The fourth graph represents a function as per the vertical line test.
To determine the function:
Simply draw a vertical line through the graph to find the number of times the function's graph is intersected by the vertical line to determine this.
The graph is said to represent a function if the vertical line only crosses it once at any given location on the graph.
A function is a relationship between a number of inputs and outputs. A function is an association of inputs where each input is coupled with exactly one output.
There is a range, co-domain, and domain for every function.
As per the given graphs,
the first three graphs do not represent a function.
only the fourth graph represents a function.

What is this in simplest form
Simplify the expression.
Exact Form:
10/9
Decimal Form:
1.¯1
Mixed Number Form:
1/1/9
Answer:
It would be 1⅑
Step-by-step explanation:
First we turn the fractions into improper fractions.
4 7/9 would now be 43/9
3 2/3 would not be 11/3
Now, we have to make them have the same “bottom number”
3x11=33, 3x3=9
Now our equation is..
43/9 - 33/9 = 10/9
When we turn it into a simplified fraction, it would be 1⅑

A local bookstore tracked the type of payments people make at their store. Out of 100 people, 40 paid with cash, 55 paid with a credit card and 5 used a gift card. Based on this information, what is a reasonable prediction of the number of people paying with cash if they had 600 customers?
Answer:
Cash = 240, Credit = 330, Gift = 30
Step-by-step explanation:
We know from this the precentage of people using different payment methods
Cash = 40/100 = 40%
Credit card = 55/100 = 55%
Gift card = 5%
We can then find the number of people using each method regardless of total amount of people
Cash = 40% * 600 = 240
Credit = 55% * 600 = 330
Gift card = 5% * 600 = 30
Total = 240 + 30 + 330= 600
Answer:
240
Step-by-step explanation:
Set up a proportion. Out of 100 people, 40 people paid with cash. Out of 600 people, x people paid with cash.
[tex]\frac{40}{100} =\frac{x}{600}[/tex]
Cross multiply and solve for x.
[tex]24000 = 100x\\24000/100=100x/100\\240 =x\\x=240[/tex]
240 customers paid with cash.

The elevation of a toy glider changes by -19.5 centimeters in 3 seconds.
What is the rate of the toy glider's change
in elevation?
Answer:
Basically do -19.5 divided by 3
The answer is -6.5
Step-by-step explanation:
Hope that helps :)
The rate of change in elevation is approximately -6.5 centimeters per second.
What is division?Math operations include division as one of its types. This technique involves splitting the phrases or numbers into the same amount of components.
To find the rate of change in elevation, we need to divide the change in elevation by the time it took to change.
The change in elevation is -19.5 centimeters (we use a negative sign to indicate the decrease in elevation).
The time it took to change is 3 seconds.
Therefore, the rate of change in elevation is:
rate of change = change in elevation / time
rate of change = -19.5 cm / 3 sec
rate of change ≈ -6.5 cm/sec
So the rate of change in elevation is approximately -6.5 centimeters per second.

5x - 2y = -26
-7x + 4y = 40
Show your work?
Answer:
x = -4, y = 3
Step-by-step explanation:
In one equation (let's use the top one), solve for one of the variables (let's solve for y first).
5x - 2y = - 26 --> -2y = -5x - 26 --> y = (5/2)x + 13
Now, substitute ((5/2)x + 13) in for y in the second equation.
-7x + 4((5/2)x + 13) = 40 --> -7x + 10x + 52= 40 --> 3x = -12 --> x = -4
Then, subtitute that in to one of the equations.
5(-4) - 2y = -26 --> -20 - 2y = -26 --> -2y = -6 --> y = 3

A real estate agency sells a house for $315000. The real estate agent earns a commission of 5 3/4%. The real estate agency keeps 10 1/8% of the sale. Taxes take 4 1/8%, and the rest goes to the seller. How much does the seller get from the sale of the house?
Answer:
$252000
Step-by-step explanation:
Amount of real estate without commission = $315000
Total percentage commission on sale = 5 3/4 + 10 1/8 + 4 1/8
5 3/4 + 10 1/8 + 4 1/8 = 23/4 + 81/8 + 33/8
23/4 + 81/8 + 33/8 = 46+81+33/8
23/4 + 81/8 + 33/8 = 160/8
23/4 + 81/8 + 33/8 = 20%
Hence the total percent commission is 20%
Commission amount = 20% of $315000
Commission amount = 20/100 * 315000
Commission amount = 0.2*315000
Commission amount = $63000
The amount the seller get = $315000 = $63000
The amount the seller get= $252000
