Answer:
1 1/4
Step-by-step explanation:
x=2, y=3, and z=1
1/2(2)+3/4(3)=1+3/12=1 1/4
Answer:
184 in²
Step-by-step explanation:
Given :
Width, w = 6 inches
Length, l = 10 inches
Height, h = 2 inches
To obtain how much wrapping paper is needed ; we take the surface area of the box
Surface area = 2(lw + lh + wh)
Surface area = 2((6*10) + (6*2) + (10*2))
Surface area = 2(60 + 12 + 20)
Surface area = 2(92)
Surface area = 184 in²
The amount of wrapping paper needed = 184 in²
Answer:
One piece of fabric: 10 x 6, or 60.
If one triangle is 15, she can cut 4 triangles from each piece of fabric.
If she has 24 pieces of fabric, she can cut 4 x 24, or 96 triangle patches.
Let me know if this helps!
ANSWER
A parabola.
EXPLANATION
The given conic is :
This can be rewritten as:
This is a parabola with the vertex at the origin.
The foci is (0,4)
Therefore the given conic section is a parabola that has an axis of symmetry parallel to the y-axis.
Answer:
Slope:-63
Y-intercept: (0,825)
Step-by-step explanation:
Slope= y2-y1 ÷ x2-x1
321-699 ÷ 8-2
-378 ÷ 6 =-63
Y-intercept:
y=-63x+b
to get b (y-intercept) plug in one of the points and solve.
699=-63(2)+b
699=-126+b
699+126=-126+126+b
699+126=0+b
825=b
