Multiply the total number of freshman by the percentage:
754 x 0.78 = 588.12
Since you cant have 0.12 of a person, round up to 589 people.
Approximately 589 of the freshmen at the high school would be expected to have internet access at home.
We are given that 78% of high school freshmen have internet access at home. This percentage can be expressed as a fraction or a decimal for calculation purposes. In this case, we will use the decimal form, which is 0.78.
The total number of freshmen at the high school is given as 754.
To find the number of freshmen with internet access, we multiply the total number of freshmen by the percentage (in decimal form) that represents those with internet access.
The calculation is as follows:
Number of freshmen with internet access = Total number of freshmen × Percentage with internet access
Number of freshmen with internet access = 754 × 0.78
Performing the multiplication:
Number of freshmen with internet access = 588.92
In conclusion, about 589 of the 754 freshmen at the high school would be expected to have internet access at home.

Abby caught a fish that was 10 3/8 inches long. Brandon caught a fish that was 8 5/8 inches long. How much longer was Abby's fish than Brandon's fish?
what you do is take 5 away from 3. No! Borrow 1 Whole (9) and makes it 9 13/8 - 8 5/8 then subtract the 2 fractions
[tex] \frac{13}{8} - \frac{5}{8} ...[/tex]
and that is
[tex] \frac{8}{8} [/tex]
then convert that into 1 whole. Now add the whole to the 9 and thats 10. Now, subtract the 2 whole numbers. 10-8=2 so the answer is 2

Now you subtract 350 from both sides. -40x is greater than negative 310. Divide by -40 on both sides and flip the sign since you are dividing by a negative. x<31/4 or 7.75, so round down and she can only have 7 exhibits
Answer:
she can have at most seven exhibits
Step-by-step explanation:
do 350-40 because that is the amount of space needed for a walkwaynext do 310/40 because that is the amount of space is needed for each exhibitround 7.75 down because you can't have part of an exhibit:)solve x^2+10x=24 by completing the sqaure. which is the solution set of the equation
Answer:
{-12, 2}
Step-by-step explanation:
x^2 + 10x = 24
Take half of the x-term coefficient and square it. Add that to both sides.
Half of 10 is 5. 5^2 = 25.
x^2 + 10x + 25 = 24 + 25
(x + 5)^2 = 49
x + 5 = +/-sqrt(49)
x + 5 = 7 or x + 5 = -7
x = 2 or x = -12

One diagonal of a kite is twice as long as the other diagonal. If the area of the kite is 400 square meters, what are the lengths of the diagonals?
Answer:
20m and 40m
Step-by-step explanation:
The area (A) of a kite is calculated using the formula
A = [tex]\frac{1}{2}[/tex] product of diagonals
Let one diagonal be d then the other diagonal is 2d ( twice as long )
Hence
[tex]\frac{1}{2}[/tex] × 2d × d = 400
d² = 400 ← take the square root of both sides
d = [tex]\sqrt{400}[/tex] = 20
and 2d = 2 × 20 = 40
The diagonals are 20m and 40m in length
The lengths of the diagonals of a kite, where the area is 400 square meters and one diagonal is twice the length of the other, are 20 meters for the shorter diagonal and 40 meters for the longer diagonal.
Explanation:You asked how the lengths of the diagonals of a kite can be determined given that the area is 400 square meters and one diagonal is twice as long as the other. To find the diagonals, we'll use the formula for the area of a kite, which is Area = (d1 * d2) / 2, where d1 and d2 are the lengths of the diagonals.
Let's denote the shorter diagonal as d, which means the longer diagonal is 2d. Plugging these into the area formula gives us:
400 m2 = (d * 2d) / 2
Multiplying both sides by 2 gives us 800 m2 = d * 2d, which simplifies to 800 m2 = 2d2.
Dividing both sides by 2 gives us 400 m2 = d2. Taking the square root of both sides, we find that d = 20 meters. Hence, the longer diagonal is 2 * 20 meters = 40 meters.
The lengths of the diagonals of the kite are 20 meters and 40 meters.

Kay was walking along the bridge above the river. She accidentally lost her grip on her camera when she was trying to get it out to photograph massive birds nest in the trees.The height of the camera above the water can be modeled by the equation y=-16t^2+400, where t represents the seconds after the camera is dropped. How long will it take before Kay sees the splash from the camera hitting the water.
Answer:
5 seconds it will hit the water.
Step-by-step explanation:
y=-16t²+400
add -16t² to both sides
-16t²=-400
divide both sides by 16
t²=-25
t=√25

Answer:
t=5
Step-by-step explanation:
t=√25=t=5
■ ■I_____I7 POINTS!!! ~ A 6 foot tall man casts a shadow that is 4.5 feet long. A telephone pole casts a shadow that is 15.6 feet long. Two similar triangles are created. How tall is the telephone pole?
The answer is:
The telephone pole is 20.8 foot tall.
Why?Since it's not mentioned, we can assume that both, man and the telephone pole are close, so, if two similar triangles are created, we know that both shadows are proportional and we can find the telephone pole height creating a proportionality relationship.
We can find the telephone pole height using the following equation,
[tex]\frac{ManHeight}{ManShadow}=\frac{PoleHeight}{PoleShadow}[/tex]
Were,
Man height is 6 foot
Man shadow is 4.5 feet long
Telephone pole shadow is 15.6 feet long.
So, substituting we have:
[tex]\frac{6}{4.5}=\frac{PoleHeight}{15.6}[/tex]
[tex]PoleHeight=15.6*\frac{6}{1.5}=20.8ft[/tex]
So, the telephone pole is 20.8 foot tall.
Have a nice day!

Answer:
The answer in the procedure
Step-by-step explanation:
we have
x+2y > 6
Isolate the variable y
y > -0.5x+3
The solution of this inequality is the shaded area above the dashed line
The equation of the dashed line is y=-0.5x+3
The slope of the dashed line is negative (m=-0.5)
The y-intercept of the dashed line is 3 (value of y when the value of x is equal to zero)
The x-intercept of the dashed line is 6 (value of x when the value of y is equal to zero)
Plot the intercepts to draw the dashed line and shaded the area above the dashed line

Find the surface area of the shape below
Answer:
464 in²
Step-by-step explanation:
Surface area of a figure is the total area of its sides.
We shall assume that the shape is a solid.
2 × (5 × 10) = 2 × 50 = 100
2 × 1/2 × 4(10+16) = 4 × 26 = 104
10 × 10 = 100
10 × 16 = 160
Total area = 100 + 104 + 100 + 160
= 464 in²
The surface area of a shape can be found by using specific formulas that differ depending on the shape's dimensions and type. For a sphere, the formula is A = 4πr², while for a rectangle, it's A = length × width. Other shapes like a cylinder require calculating the area of each side then adding them together.
Explanation:In order to find the surface area of a shape, we first need to know the dimensions and type of the shape. For example, to find the area of a sphere, you'd use the formula A = 4πr², where 'r' is the radius of the sphere. To find the area of a rectangle, you'd use A = length × width.
If we're talking about a more complex shape, like a cylinder, we need to calculate the area of each face or side separately and then add them together for the total surface area. For example, the total surface area of a cylinder is given by A = 2πr(r + h), where 'r' is the radius of the base and 'h' is the height of the cylinder.
These are just a few examples. The calculation of the surface area will depend on the specific dimensions and type of the shape in question.

use the substituition method to solve the system of equation. choose the correct ordered pair 2x+y=8 y= -x+5
The answer is:
[tex]x=3\\y=2[/tex]
Ordered pair: (3,2)
Why?The substitution method for solving system of equations consists in finding the solution by isolating and substituting each variable value into the given equations, doing that, all the variable value can be found.
So, we are given two equations:
[tex]2x+y=8\\y= -x+5[/tex]
We need to substitute (y) into the first equation,so:
[tex]2x+(-x+5)=8[/tex]
[tex]2x-x+5=8[/tex]
[tex]x+5=8[/tex]
[tex]x=8-5[/tex]
[tex]x=3[/tex]
Now that we know "x" we need to substitute it into the second equation, so:
[tex]y=-(3)+5[/tex]
[tex]y=2[/tex]
Hence,
[tex]x=3\\y=2[/tex]
So, the ordered pair will be: (3,2)
Have a nice day!
Answer:
Ordered pair = (3, 2)
Step-by-step explanation:
We are given the following equations and we are to solve them by substitution method:
[tex]2x+y=8[/tex] --- (1)
[tex]y= -x+5[/tex] --- (2)
Substituting the value of y from equation (2) to (1):
[tex]2x+(-x+5) = 8[/tex]
[tex]2x-x+5=8[/tex]
[tex]x = 8-5[/tex]
x = 3
Substituting this value of x in equation (2):
[tex]y = -(3)+5[/tex]
y = 2
So the ordered pair is (3, 2).
