Answer:
x^2/400 + x^2/625
(x-0)^2/400) +(y-0^2/625)
x^2=400
X=sqrt. 400
x = 20
y^2=625
y = sqrt. 625
y= 25
a^2-c^2=b^2
sqrt 400-625 = c
20-25=c
The correct answer is c=-5
(-5,0)
(5,0)
Step-by-step explanation:
The answer would end up being n<-5
Step-by-step explanation:
4n/4 < -20/4
=<-5
Answer:
gradient m = - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
y = - x - 3 ← is in slope- intercept form
with gradient m = - 1
Answer:
we know all angles are 90° in the rectangle
therefore, angle d = bdc+bda = 90
=> 31+bda = 90
=>angle bda= 59
Answer:
85.1 g
Step-by-step explanation:
Boris has 91.5 g of pepper
He used 0.4g to make one plate of scrambled egg
If she made 16 plates of scrambled egg then the amount of pepper that will be left can be calculated as follows
= 0.4×16
= 6.4g
= 91.5g - 6.4g
= 85.1g
Hence Boris will have 85.1g of pepper left
