Answer:
jojo is 26
esi is 13
and kweku is 8 years old.
Step-by-step explanation:
Let esi's age be x then jojo's age is 2x.
Also kweku's age is x - 5. as esi is 5 years older than kweku.
So x + 2x + x - 5 = 47
4x = 47 + 5 = 52
x = 13.
So jojo's age is 2*13 = 26 and kweku's age is 13 - 5 = 8.
A typist can type 4800 words per hour. How many words can she type in 1 minute?
(Using direct proportion)
Answer: 80
1 hour= 60mins
So to know how many words can she type in 1 min, we do the math "4800 : 60"

Step-by-step explanation:
Find the measure of the missing angles.
100°
b =
C=
Answer:
<b = 80
<c = 80
Step-by-step explanation:
<b and 100 form a straight line so they add to 180
<b +100 =180
<b = 180-100
<b = 80
angles b and c are vertical angles and vertical angles are equal
<c = <b = 80

What is the leading coefficient of 8 -5x+x^3-2x^4
Answer:
-2
Step-by-step explanation:
8 -5x+x^3-2x^4
Write the polynomial from highest power of x to lowest power of x
-2x^4+x^3-5x+8
The leading coefficient is the number in front of the highest power of x

(I think I remember your other information correctly.)
Step-by-step explanation:
I think you said you were given
*Integral from x=-5 to x=0 of g was -14
*Integral from x=-5 to x=6 of g was 6
Asked to find integral( g(x) + 2 , from x=0 to x=6)
Yes this can be split into two integrals:
Integral(g(x), x=0 to x=6) + Integral(2, x=0 to x=6)
The last integral is easier... the antiderivative or 2 is 2x. So evaluate 2x as the limits and subtract. Always plug in the top limit first. 2(6)-2(0)=12-0=12
Let's start with the bigger interval from x=-5 to x=6 which was 6... and since we want to get rid of the interval from x=-5 to x=0 to find the integral of g from x=0 to 6, all we must do is do 6-(-14)=20.
Integral( g(x) + 2 , from x=0 to x=6)
=
Integral(g(x), x=0 to x=6) + Integral(2, x=0 to x=6)
=
20+12

how many parts of the gray 3/8 are covered by the gray 1/4 ?
2 parts = 2/8 are clearly covered by 1/4.
2/8 is what part of 3/8 ?
it is the same question as "2 is what part of 3" ?
is 2 a quarter (1/4) of 3 ? no, 1/4×3 = 3/4 and not 2.
is 2 one third (1/3) of 3 ? no, 1/3 of 3 = 1/3×3 = 1 and not 2.
is 2 two thirds (2/3) of 3 ? ah, 2/3 × 3 = 2. that is correct !
is 2 three quarters (3/4) of 3 ? no, 3/4×3 = 9/4 and not 2.
once you have the same denominator, you can easily compare the numerators and ignore the denominators for such problems.

Find the surface area of the triangular prism
what is simplfiled for x^8 y^2 / x^3 y^9
Answer:
x^5/y^7
Step-by-step explanation:
x^8 y^2 / x^3 y^9
We know that a^b/ a^c = a^(b-c)
Simplify the x terms
x^8 / x^3 = x^(8-3) = x^5
Simplify the y terms
y^2 / y^9 = y^(2-9) = y^-7
We know a^-b = 1/a^b
y^-7 = 1/y^7
Put the terms back together
x^5/y^7

Find angle CBA
pls help
Answer:
40
Step-by-step explanation:
u can draw a line at point c parallel to line ab
angle at d and lower part of c is interior angle so u can find the value at lower part of c that is 180-145=35
so point c 75-35=40 is upper part of point c
upper part of c and angle b is alternate angle so both angle are the same
angle cba is 40
Answer:
<CBA = 40°
Step-by-step explanation:
If AB is parallel to DE, you can make an irregular pentagon by continuing AB and drawing a line perpendicular to DE. The sum of the interior angles of a pentagon is 540. You can use this to solve for the supplement of <CBA, then subtract that from 180. (I’m sure there’s an easier way, but I cant think of one right now).
540-90-90-145-75=x
140=x
<CBA=180-140= 40°
