Answer:
12:15pm
Step-by-step explanation:
1hr=60mins
1hr +15mins= 75 minutes
11:00am + 60mins (1hr)= 12pm
12pm + 15mins= 12:15pm
Hope this helps!
Answer:
The radius of the circle A is times greater than the radius of circle B
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x----> the area of the clock A
y----> the area of the clock B
-----> equation A
we have
-----> equation B
substitute equation B in equation A
square root both sides
step 2
Find how many times greater is the radius of Clock A than the Clock B radius
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor
Let
z-----> the scale factor
x----> the radius of the clock A
y----> the radius of the clock B
we have
substitute
therefore
The radius of the circle A is times greater than the radius of circle B
Answer:
(f-g)(x)=-x^(2)+2x+8
the solutions are:
<em><u>x=4 or x=-2</u></em>
Step-by-step explanation:
(f-g)(x)=2x+1-(x^(2)-7)
(f-g)(x)=-x^(2)+2x+1+7
(f-g)(x)=-x^(2)+2x+8
does this help or should I solve for the zeros/solutions of this quadratic equation?
then:
-x^(2)+2x+8=0
-(x^(2)-2x-8)=0
x^(2)-2x-8=0
(x-4)(x+2)=0
<em><u>x=4 or x=-2</u></em>
Answer:
yards
Step-by-step explanation:
We have been given that 4 1/2 yards of cloth are needed to make a woman’s dress. 2 2/7 yards of cloth are needed to make a girl’s dress.
To find the yards of more cloth needed to make a woman’s dress than a girl’s dress, we will subtract cloth needed for girl's dress from the cloth needed for woman's dress.
Convert mixed fraction into improper fraction:
Make a common denominator:
Therefore, yards more cloth is needed to make a woman’s dress than a girl’s dress.
