Answer:
171
Step-by-step explanation:
180×95/100
180×95=17100
17100/100=171.
That is how I got my answer.
Answer:
Intercept = - 3 ; slope = 18
Step-by-step explanation:
Given the points :
(3, 51) ; (5, 87)
x1 =3, y1 = 51, x2 = 5 ; y2 = 87
Slope intercept relation:
y = mx + c
m = slope ; c = intercept ; x and y are x, y vlayes respectively
Slope (m) = (y2 - y1) / (x2 - x1)
Slope (m) = (87 - 51) / (5 - 3)
Slope = 36 / 2
Slope (m) = 18
The intercept c :
m = 18 ; x = 5 ; y = 87
Substitute values into the slope intercept formula :
87 = 18(5) + c
87 = 90 + c
c = 87 - 90
c = - 3
Intercept = - 3
Answer:
16 square units.
Step-by-step explanation:
We know that any diagonal of a rhombus divides the rhombus into two equal parts having the same area.
Now. the area of Δ ABC can be calculated from the coordinates of its three vertices.
Here, A(-1,4), B(3,2) and C(-1,0) are given.
Hence, the area of Δ ABC will be
square units.
Therefore, area of the rhombus will be (8 × 2) = 16 square units. (Answer)
Note: If the three vertices of a triangle ABC are given to be (x1,y1), (x2,y2), and (x3,y3), then area of the triangle will br given by
.
Answer:
<h2>BC = 30</h2>
Step-by-step explanation:
Look at the picture.
The equation:
<em>combine like terms</em>
<em>subtract 8 from both sides</em>
<em>divide both sides by 5</em>
- put x = 8:
3 1/4 cups of oatmeal
How many 1/4 cups, would be: 3 1/4 ÷ 1/4
= 13 / 4 ÷ 1/4
= 13 / 4 × 4/1
= 13/1
= 13
She will use 13 one fourth cups.
