Answer:
2028 square inches
Step-by-step explanation:
The side length of the styrofoam cube measures 6 1/2 inches.
Step 1
We find the surface area of a cube
The formula is given as
Surface Area = 6a²
Where a = Side length of the cube = 6 1/2 inches
Hence,
Surface area of a cube = 6 × (6 1/2inches)²
= 253.5 square inches
Step 2
Huy is painting eight styrofoam cubes for a science project.
The total surface area that Huy will paint is calculated as:
1 styrofoam cube = 253.5 square inches
8 styrofoam cubes = x
Cross Mulitiply
x = 8 × 253.5 square inches
x = 2028 square inches
Therefore, the total surface area that Huy will paint is 2028 square inches.

Sheila threw the discus 24 meters, which was 0.38 meter farther than Tiesha threw the discus. How far, in meters, did Tiesha throw the discus?
Answer:
23.62 meters
Step-by-step explanation:
Find how far Tiesha threw the discus by subtracting 0.38 from 24:
24 - 0.38
= 23.62
So, Tiesha threw the discus 23.62 meters
Jeff has 4 red pens and 2 blue pens in his backpack. He also has 3 yellow highlighters and 2 green highlighters in his backpack. If he reaches into his backpack and grabs one pen and one highlighter without looking, what is the probability that he will grab a red pen and a yellow highlighter?
Answer:
1/15
Step-by-step explanation:
In probability,
"AND" means "multiplication"
"OR" means "ADDITION"
We want probability of Blue Pen and Yellow Highlighter. So we find individual probabilities and "MULTIPLY" them.
Let P(b) be probability of blue pen
Let P(y) be probability of yellow highlighter
We know probability of event is that event divided by total number of that
So,
There are 4 + 2 = 6 pens
Blue pen = 2
Hence,
P(b) = 2/6 = 1/3
And,
There are 5 highlighters
Yellow highlighter = 1
Hence,
P(y) = 1/5
Now,
P(b and y) = 1/3 * 1/5 = 1/15
Hence,
probability of grabbing blue pen and a yellow highlighter is 1/15
Three yrs hence, a men will be three time his brother age and the sum of present age is 18 find their present age
Answer:
Step-by-step explanation:
Let the age of a man = x
Age of his brother = y
Three yrs hence, a man will be three time his brother age
This is written as:
x + 3 = 3(y + 3)
x + 3 = 3y + 9 .... Equation 1
The sum of present age is 18
= x + y = 18
x = 18 - y
We substitute 18 - y for x in Equation 1
find their present age
18 - y + 3 = 3y + 9
Collect like terms
21 - 9 = 3y + y
12 = 4y
y = 12/4
y = 3 years
x = 18 - y
x = 18 - 3
x = 15 years
2x^2+11x+5=0
Check all that apply
Answer:
B and F
Step-by-step explanation:
X = -1/2
X = -5
Answer:
x = -1/2, x = -5
Step-by-step explanation:
2x^2+11x+5 = 0
Solve by factoring:
(2x+1)(x+5) = 0, or:
(2x+1) = 0
(x+5) = 0
(2x+1) = 0: x = -1/2
(x+5) = 0: x = -5

Answer:how many terms are there? 4
whats the coefficient of the 3rd term? -2
what is the constant? 12
Step-by-step explanation:
12, 2x^3, -2x, and -5x^2 are each one term, adding up to 4 terms
the third term is -2x, with -2 as the coefficient and x as the variable
lastly, the constant is a value in an equation with no x, in this case it’s 12
A triangle has vertices of (−3, 3), (−3, 2), and (1, −2). What are the coordinates after dilating from the origin by a scale factor of 1 2 ?
Answer:
(-1.5, 1.5), '(-1.5, 1) and (0.5, -1)
Step-by-step explanation:
Given the coordinate (x, y) If dilated by a factor k, the resulting coordinate will be (kx, ky).
Similarly given the coordinates of a triangle (−3, 3), (−3, 2), and (1, −2)
when dilated by a factor of 1/2, the new coordinates will be at;
A (-3, 3) = A'(1/2*-3, 1/2 * 3) = A'(-1.5, 1.5)
B (-3, 2) = B'(1/2*-3, 1/2 * 2) = B'(-1.5, 1)
C (1, -2) = C'(1/2*1, 1/2 * -2) = C'(0.5, -1)

La proporción de empleados de una empresa que usan su auto para ir al trabajo es 5:16. Si hay un total de 800 empleados, diga la cantidad de autos que se espera que haya estacionados en un día laboral en la zona dedicada a empleados.
Answer:
250 coches
Step-by-step explanation:
Tenemos la siguiente información de la pregunta;
Proporción de empleados que vienen a trabajar con sus coches = 5/16
Número total de empleados = 800
Por lo tanto, número total de automóviles esperado = proporción de empleados que vienen a trabajar con automóviles * número total de empleados
número total de coches esperados = 5/16 * 800
número total de coches esperados = 250 coches

A triangle has sides with length of 11 feet 12 feet and 13 feet. Is it a right triangle
Answer:
No
Step-by-step explanation:
It will be a right triangle if it follows Pyhthagoras Theorem . Where the sum of squares of two smaller sides is equal to the square of the 3rd side. Let's check ,
→ 11²+ 12² = 13²
→ 121 + 144 = 169
→ 265 ≠ 169

Write the point-slope form of the equation of the line through the given points.
(4,-4), slope = -2
Oy+4 = –2(x – 4)
Oy - 4= 2(x + 4)
Oy+2 = 4(x - 4)
Oy - 2 = 4(x +4)
Terms
Answer:
first option
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here m = - 2 and (a, b ) = (4, - 4 ) , then
y - (- 4) = - 2(x - 4) , that is
y + 4 = - 2(x - 4)

HURRY PLEASEE!! A new health drink has 140% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 50mg. How many milligrams of the vitamin are in the drink?
Answer:
50+0.4*50
Step-by-step explanation:
Because it has 140% of the RDA and the RDA is 50, that means it has 50 and 40% or 0.4 of 50. So the answer is 70 mg.
There are 5,000 trout in a lake, the population decreases 2% yearly. How many trout will there be after 4 years?
Answer:
4,600
Step-by-step explanation:
First you find 2% of 5,000 which is 100 then you determine 2% every 4 years which is 100x4 which equals 400. then subtract 400 from 5,000 which gets you 4,600
Answer:
4600
Step-by-step explanation:
2% of 5000 is 100
100 x 4 = 400
5000 - 400 = 4600

A milk truck has a diameter of 10 and feet and a height of 50 feet. How much milk can the truck hold?
Answer:
The mentioned milk truck can hold:
3927 ft^3 of milk.Step-by-step explanation:
As you can see, the question is asking about the volume of the milk truck, to obtain the volume of a cylinder, first we must to find the area of the surface side, in this case is a circle, to find the area of a circle when we have the diameter is:
Area of a circle = [tex]\pi *\frac{\ D^{2} }{4}[/tex]Where D is the diameter given (10 feet), now we replace and operate:
Area of a circle = [tex]\pi *\frac{\ (10 ft)^{2} }{4}[/tex]Area of a circle = [tex]\pi *\frac{\ 100 ft^{2} }{4}[/tex]Area of a circle = [tex]\pi *25 ft^{2}[/tex]Area of a circle = 78.54 ft^2 approximatelyNow, with the data of the area, we can calculate the volume with the formula below:
Volume of a cylinder = Area of the circle * heightVolume of a cylinder = 78.54 ft^2 * 50 ftVolume of a cylinder = 3927 ft^3With the calculations, we can see the milk truck can hold 3927 cubic feet of milk with those dimensions.
