Answer:
1:u
Step-by-step explanation:
Grey slabs = 1/5 of total slab
Say total slab = x
Then,
Grey slabs = 1x/5
We can represent
Yellow slabs = u/5
Then ratio of Grey to yellow would be;
Gray slabs / Yellow slabs = (1x/5)/(u/5)
=1/u
= 1:u
Since there are 55 slabs in total, then
Yellow slab would be = 55/5 = 11
What is the solution to this system of equations? 5x + 2y= 29
x + 4y = 13
A x = 5, y = 3
B. x=2, y=5
C. X= 5, y = 2
D. x= 3, y = 2
Answer:
C
Step-by-step explanation:
Given the 2 equations
5x + 2y = 29 → (1)
x + 4y = 13 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the y- term
- 10x - 4y = - 58 → (3)
Add (2) and (3) term by term to eliminate y
- 9x + 0 = - 45
- 9x = - 45 ( divide both sides by - 9 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (2)
5 + 4y = 13 ( subtract 5 from both sides )
4y = 8 ( divide both sides by 4 )
y = 2
Solution is x = 5, y = 2 → C
Answer:
c) x = 5, y = 2

Help me with this question please
Answer:
Part A: 14
Part B: 10
Step-by-step explanation:
Since the ratio to each paint is the same...
(red/yellow) 2/5=x/35
Cross Multipy
5x=70
x=70/5
x=14
Repeat the same thing but replace 35 with 25 for Part B
2/5=x/25
Cross Multiply
5x=50
x=10

Answer:
quadrant 2!
Step-by-step explanation:
Analyze the drawing.The beam in the mobile is balanced.The cups on the right and left are equal,which means the the items can be removed and mobile still balances.This leaves 4 circles on the left,a cup and 1 circle on the right.Now the circle on the right cancels out the circle on the left,leaving three circles on the right.The logical conclusion is that the cup is equal to 3 circles

Can someone please help me?
Answer:
Answer choice D
Step-by-step explanation:
So we need to get r to the right side. First we can multiply by 3 to get rid of the fraction:
3V=4[tex]\pi[/tex][tex]r^{3}[/tex]
Then we can divide both sides by 4[tex]\pi[/tex] to get r by itself:
[tex]\frac{3V}{4\pi } = r^{3}[/tex]
Then cube both sides:
[tex]\sqrt[3]{\frac{3V}{4\pi } } =r\\[/tex]

−10ba+15ba^2
−5b+2a−3a^2
10ba−15ba^2
Answer:
−10ba+15ba^2
Step-by-step explanation:
The product of the given monomial and binomial is -10ab+15a²b.
The given expression is −5b(2a−3a²).
We need to simplify the polynomial using multiplication.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Binomials are also a kind of polynomials consisting of only two terms. A binomial is defined as an algebraic expression consisting of two terms that are separated by the arithmetic signs, either the addition sign (+) or the subtraction sign (-). When multiplying a monomial by a binomial, we follow the distributive law of multiplication.
Now, 2a×(−5b)−3a²×(−5b)
=-10ab+15a²b
Therefore, the product of the given monomial and binomial is -10ab+15a²b.

Solve the system by substitution.
y = 5x
y = 9x + 8
Answer:
(-2,-10)
Step-by-step explanation:
So if y=5x and if y=9x+8 then those should be able to equal each other (substitution):
5x=9x+8
Subtract 5x from both sides:
0=4x+8
Subtract 8 from both sides:
-8=4x
Divide both sides by 4:
x=-2
If x=-2, then we can just plug it back into the first equation:
y=5(-2)
Simplify:
y=-10
Answer:
x = -2
y = -10
Step-by-step explanation:
So if y = 5x
Then you can put that in place of the y
5x = 9x + 8
Get the x's all on one side by subtracting
-4x = 8
Divide both sides by -4
x = -2
Then insert x into the first equation, so
y = 5(-2)
y = -10

(a) The diagram shows a circle, centre 0. AB and CD are chord.
Given that OM = 8 cm, NT = 3 cm, AB = 30 cm.
(1) Calculate the radius
(2) Calculate the length of CD
Answer:
1) Radius = 17 cm
2). CD = 19.3 cm
Step-by-step explanation:
1). O is the center of the given circle.
By joining the center and point A located at the circumference of the circle,
OA = radius of the circle.
Length of chord AB = 30 cm
"Line from the center of a circle to the chord inside the circle is a perpendicular bisector of the chord"
By the given property, OM equally divides the chord AB.
AM = MB
AM = [tex]\frac{1}{2}(AB)[/tex]
AM = [tex]\frac{10}{2}[/tex] = 5 cm
By applying Pythagoras theorem in ΔOAM,
AO² = OM² + AM²
AO² = 8² + 15²
AO = √289
AO = 17 cm
Therefore, radius of the circle = 17 cm
2). Since, OT, OC and OA are the radii of the given circle,
OT = OC = OA = 17 cm
ON = OT - NT
= 17 - 3
= 14 cm
By applying Pythagoras theorem in ΔOCM,
OC² = ON² + CN²
17² = 14² + CN²
CN = [tex]\sqrt{(17^2-14^2)}[/tex]
= [tex]\sqrt{93}[/tex]
= 9.64 cm
Since, CD = 2(CN)
CD = 2 × 9.64
= 19.29 cm
≈ 19.3 cm
