Answer:
12
Step-by-step explanation:
List out factors of 60 =
1 x 60 = 60
2 x 30 = 60
3 x 20 = 60
4 x 15 = 60
5 x 12 = 60
6 x 10 = 60
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60 are factors of 60.
List out multiples of 6 from 10 to 20.
12 and 18.
Since 12 is seen on one of the factors of 60 and a multiple of 6 between 10 and 20, the answer is 12.
Malaya is following this recipe for bread rolls.
She uses 400 g of flour.
How much of the other ingredients does she use?
Recipe: Makes 14 bread rolls
700 g flour
14 g salt
7 g yeast
35 mL oil
420 mL water
Answer:
Step-by-step explanation:
400/700 = 4/7
salt: 4/7 × 14 g = 8 g
yeast: 4/7 × 7 g = 4 g
oil: 4/7 × 35 mL = 20 mL
water: 4/7 × 420 mL = 240 mL

Given:
The system of equation is

[tex]y=-\dfrac{1}{3}x-4[/tex]
To find:
The solution of given system of equations.
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
Write the given equation in slope intercept form.
The first equation is
[tex]y-8=-\dfrac{1}{3}x-4[/tex]
[tex]y=-\dfrac{1}{3}x-4+8[/tex]
[tex]y=-\dfrac{1}{3}x+4[/tex] ...(i)
Here, slope is [tex]-\dfrac{1}{3}[/tex] and y-intercept is 4.
The second equation is
[tex]y=-\dfrac{1}{3}x-4[/tex] ...(i)
Here, slope is [tex]-\dfrac{1}{3}[/tex] and y-intercept is -4.
Since the slopes of both lines are same but the y-intercepts are different, therefore the given equations represent parallel lines.
Parallel lines never intersect each other. So, the given system of equation has no solution.
Hence, the correct option is B.

2y - 5x = 9
4y + 3x = 5
Do not use trial and improvement
Answer:
y = 2, x = -1
Step-by-step explanation:
2y - 5x = 9
2y = 9+5x
y = (9+5x) /2
4y + 3x = 5
4((9+5x) /2) + 3x = 5
13x + 18 = 5
13x = -13
x = -1
y = (9+5x) /2
y = (9+5(-1)) /2
y = 2
Answer:
x = -1, y = 2
Step-by-step explanation:
2y - 5x = 9
4y + 3x = 5
eliminate one of the variables by multiplying the equations and then adding them together.
3(2y - 5x = 9)
5(4y + 3x = 5)
6y - 15x = 27
20y + 15x = 25
26y = 52
y = 2
now input the value of y into one of the original equations to find x.
8 + 3x = 5
8-5 = 3
x = -1

Step-by-step explanation:
I took the quiz and got it wrong, but it told me the correct answer
A right isosceles triangle has exactly 2 equal sides and one right angle.
Given that, a triangle has exactly 2 equal sides and one right angle.
Isosceles triangle: An isosceles triangle is a triangle that has two sides of equal length.
Right isosceles triangle: An isosceles right triangle is defined as a right-angled triangle with an equal base and height which are also known as the legs of the triangle.
Obtuse isosceles: An isosceles obtuse triangle is a triangle in which one of the three angles is obtuse (lies between 90° and 180°), and the other two acute angles are equal in measurement.
Right triangle: A right triangle is a triangle in which one angle is 90°.
Hence, right isosceles triangle has exactly 2 equal sides and one right angle.

Z
W
Y
What is the measure of angle W?
25°
65°
1150
120°
Answer:
115 degrees
Step-by-step explanation:
We know that angle y is 45 degrees and angle z is 70 degrees so to find x, you do 180-45-70 to get 65 degrees.
Because W plus X has to equal 180 degrees, 180-65=115, so the answer is 115 degrees
Answer:
choice 3) W = 115 degrees
Step-by-step explanation:
all triangle interior angles add up to 180 degrees
180 = 45 + 70 + X
X = 65 degrees
Angle W is supplemental to angle X (angle W and angle X add up to 180 degrees.)
W = 180 - 65 = 115 degrees

15 lb ≈ ? kg
Answer:
6.82 kg
Step-by-step explanation:
set up a proportion based on 2.2 lbs in 1 kg
2.2/1 = 15/x
cross-multiply:
2.2x = 15
x = 6.82
The value of 15 lb in kg is 6.81 kg.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We know that;
⇒ 1 lb = 0.454 kg
Hence, We get;
⇒ 1 lb = 0.454 kg
⇒ 15 lb = 15 × 0.454 kg
= 6.81 kg
Thus, We get;
⇒ 15 lb = 6.81 kg

Linda and Philip share £54 in the ratio 4:5. Find how much money each of them will recieve
Answer:
Linda has £24 and Philip has £30.
Step-by-step explanation:
Denote a variable to the amount of money Linda and Philip have:
Money Linda has = L
Money Philip has = P
L + P = 54
There is a ratio of 4:5 so for every £4 Linda has, Philip will have £5. When adding both values, 4+5, you get 9.
Divide the total amount of money by the sum of the ratio numbers so 54/9 which gives 6.
Multiply the number you get from the division by their respective ratios.
Linda = 6 * 4 = 24
Philip = 6 * 5 = 30
Add both numbers if you want to make sure the answer is correct.

1. The height of a missile t seconds after it has been fired is given by h=4.9t^2+44.1t. How many seconds will it take for the rocket to reach its greatest height?
Answer:
The rocket will take 4.5 seconds to reach its maximum height.
Step-by-step explanation:
The height of a missile t seconds after it has been fired is given by h=-4.9*t²+44.1*t
This function is a quadratic function of the form f (x) = a*x² + b*x + c. In this case a=-4.9, b=44.1 and c=0
To calculate how many seconds it will take for the rocket to reach its maximum height, I must calculate the maximum of the function. The maximum of a quadratic function is the vertex of the parabola. The x coordinate of the vertex will be simply: [tex]x=\frac{-b}{2*a}[/tex]. The y coordinate of the vertex corresponds to the function evaluated at that point.
In this case the x coordinate of the vertex corresponds to the t coordinate. In other words, by calculating the x coordinate of the vertex, you are calculating the maximum time t it will take for the rocket to reach its maximum height. So:
[tex]t=\frac{44.1}{2*(-4.9)}[/tex]
t=4.5
The rocket will take 4.5 seconds to reach its maximum height.
