Cece is finding the surface area of a square pyramid by finding the sum of the areas of its faces. Which statement best describes the faces of the pyramid?
A)one square and three triangles
B)one square and four triangles
C)three squares and one triangle
D)three squares and two triangles
Answer:
D. One square and four triangles
Step-by-step explanation:
Cece is finding the surface area of a square pyramid by finding the sum of the areas of its faces
Square pyramid has a square base.
each edge of the square base joins at the top of the vertex to make a pyramid
The sides of the pyramid is a triangle
the square has 4 sides, so four triangle on the sides of the pyramid
Hence one square and four triangles forms a square pyramid
Answer:
The answer is A). one square and three triangles

Which solution set is graphed on the number line? A number line going from negative 4 to positive 4. An open circle is at 1. Everything to the left is shaded. x greater-than-or-equal-to 1 x greater-than 1 and one-third x less-than 1 x less-than-or-equal-to 1
Answer:
an open circle means it contains no equal signs.....everything to the left is shaded....means it is less then
x < 1 (thats a less then sign only) ....no equal sign in there

Step-by-step explanation:
A bike trail is drawn on a coordinate system. Each end of the trail is an x-intercept. The height of the trail is modeled by the function h(x) = -0.1x^2 - 0.3x +2.8 , where x is the horizontal distance in kilometers. How many meters is the horizontal distance of the trail?
Answer:
4metres
Step-by-step explanation:
Given the height of the trail modeled by the function h(x) = -0.1x^2 - 0.3x +2.8 , where x is the horizontal distance in kilometers
The horizontal distance occurs at the x intercept i.e at h(x) = 0
Substitute
0 = -0.1x^2 - 0.3x +2.8 ,
Multiply through by -10
0 = x^2 + 3x - 28
x^2 + 3x - 28 = 0
Factorize
x^2 + 7x - 4x - 28 = 0
x(x+7) - 4 (x+7) = 0
(x-4)(x+7) = 0
x-4 = 0 and x+7 = 0
x = 4 and -7
Since the danced cannot be negative, hence the horizontal distance of the trail is 4m

Please help! due soon!!!!!
Answer:
D
Step-by-step explanation:
First, we isolate the -4y and make the equation "4y=3x-16." Now we divide the equation by 4 to get "y=3/4(x)-4". The y-intercept in this case is -4. The only equation given that has a y-intercept of -4 is answer D.
consider the equation -2x+3y=6 write an equation in slope-intercept form

1/2 Square equals to 1/4 equals to x over 5 2 Square
therefore 1/4 equals to x over 5 2 square
Equals to 1/4 equals to x over 5 * 4 you know that 2 square equals to 4
So now I'm going to solve for 1/4 equals to x of over 5 * 4 equals to 20
1/4 equals to x over 20
1/4 equals to 20 cross multiply
= 1\4 = x/20
= 4 * x = 20*1
4x = 20
divide both side by the coefficient of x
4x/4 = 20/4
x =5

Answer:
110cm
Step-by-step explanation:
With the slice, we know that we need to find the area of a triangle with a base of 10cm and a height of 22cm.
Let 10 be x and 22 be y.
Substitute this into the equation for finding the area of a triangle.
[tex]\frac{x*y}{2}[/tex]
Which now becomes
[tex]\frac{11*20}{2}[/tex]
Which now becomes
[tex]\frac{220}{2}[/tex]
Now solve.
[tex]\frac{220}{2} = 110[/tex]
Your answer is 110cm.

3-be first to answer(this makes the chance higher for you to get the brainlist)
Answer: $48.06
Step-by-step explanation:
Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage. For example, if your product costs $50 to make and the selling price is $75, then the markup percentage would be 50%: ( $75 – $50) / $50 = . 50 x 100 = 50%.
Answer:
You would pay $48.06
Step-by-step explanation:
27*0.78 = 21.06
27 + 21.06 = 48.06

The equation of the piecewise function f(x) is below. What is the value of f(3)?
Answer:
5
Step-by-step explanation:
Ask your self which equation you should use. Since it says F(3) then we have to find an equation that would fit this correctly. For example if we look at -X^2, X<-2 we could see that 3 is clearly not less than -2, leading to the conclusion that this is not the right equation.. If you look at the last equation it says that x has to be greater/equal to 0 which is true. So then we are left with the equation...
F(3)=x+2
F(3)=3+2
F(3)=5
