1) soe soe had 15kg of flour. She used 4/5 of it to make some cookies. How many kilograms of flour had she left?
2) U Kyaw mixed red paint and blue paint in the ratio 5:3 for painting a wall. If he made 24 liters of paint for the painting job, how many litres of blue paint did he use?
Answer:
1) 3 liters left
2) 9 liters of blue paint
Step-by-step explanation:
1) 1/5 * 15 = 3
2) 3 liters of blue paint for each 8 liters.
24/8 * 3 = 9
Fractions and Comparisons
Level : JHS1.
The amount of flour used is :
= 4/5 × 15 kg
= 12 kg
The amount of flour left is :
= 15 kg - 12 kg
= 3 kg
2.
5 : 3 = Red : Blue
The amound of blue paint :
= 3 : (3 + 5) × 24 liters
= 3 : 8 × 24 liters
= 9 liters
So, the litres of blue paint did he use is 9 liters

The time it takes for an object dropped from a height to reach the ground is given by the function time (in seconds) =(1/4)√h where h is the initial height in feet. If an object dropped from a building takes 4 seconds to reach the ground what is height of the object was dropped from, to the nearest foot?
Answer:
256 ft
Step-by-step explanation:
Assuming f(t)=(1/4)√h, we can solve for h by setting 4=(1/4)√h.
4=(1/4)√h
16=√h
h= 16^2 =256 ft
Step-by-step explanation:
h = (4 ÷ ¼)²
h = (4 × 4)²
h = 16² = 256ft

Answer:
[tex]y=-0.3(x-2)^2+2[/tex]
Step-by-step explanation:
We know that the parabola faces downard, and hence must have a negative first term, so that eliminates the first and third options.
The vertex of the parabola has an x-value of 2, so it must be of the form [tex]a(x-3)^2+c[/tex].
Combining these, we have that the answer is [tex]\boxed{y=-0.3(x-2)^2+2}[/tex]

what is The expression 12+9g-30h factored using the GCF is and btw I already tryed 3
Hello!
Answer:
3(4+3g-10h)
Step-by-step explanation:
Hope this helps!
The GCF expression is 12+9g-30h is 3(4 + 3g - 10 h)
what is GCF?A group of numbers' greatest common factor (GCF) is the biggest factor that all the numbers have in common.
For example, 12, 20, and 24 have two common factors: 2 and 4.
The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
Given:
12+9g-30h
Now, to find the GCF we have to factorize the numbers
12= 2 x 2 x3
9 = 3 x 3
30= 2x 3 x 5
So, the Greatest common factor is 3.
Thus, the GCF expression is 12+9g-30h is 3(4 + 3g - 10 h)

Good day dear friends,
The expression 2L + 2W is used to find the perimeter of a rectangle with length L and width of W.
What is the perimeter of a rectangle with length 15cm and width 4cm?
Show your work.
A. 38
B. 60
C. 239
D. 23
Answer:
A, 38cm
Step-by-step explanation:
since u have to take 15cm (the length) then multiply by 2 to take both the sides of the rectangle
then you have to take the width 2 times to take the perimeter and add it up. so 15x2 and 4x2 added is 38. there!
Geometry- remember what we know about verticale angles and solve for X. Then tell me the measure of angle A.
Answer:
m<A = 32°
Step-by-step explanation:
When angles are vertical, it means they are equal to each other:
m<A = m<C
4x - 8 = 2x + 12
4x - 2x = 12 + 8
2x = 20

x = 10
Solve for A:
4x - 8
4(10) - 8

The length of a rectangle is six times its width.
If the perimeter of the rectangle is 70 cm, find its length and width.
Answer:
Length = 30
Width = 5
Step-by-step explanation:
So the formula for perimeter is
P = 2L+2W
And we know that:
L = 6W
So then we put in all the information that we do know
70 = 2(6W)+2W
And pop that into a calculator and you get W=5
So now we put that information into L = 6W to get:
L = 6×5
L = 30

Can you solve this equation with work? I can't figure out how to show my work for this one.
2(y+x+14) = 14 + 2x
2(y + x + 14) = 14 + 2x
2(y) + 2(x) + 2(14) = 14 + 2x
2y + 2x + 28 = 14 + 2x
2y + 2x - 2x = 14 - 28
2y = -14
2y / 2 = -14 / 2

Solve the following system of equations graphically on the set of axes below. y = x - 3 y = - 3/5x + 5
Answer:
Solution by graphing: (5, 2)
Step-by-step explanation:
y = x - 3
y = - 3/5x + 5
To solve systems of linear equations graphically, you'll have graph each equation using 2 pairs of points.
A great starting point is always using its intercepts:
y = x - 3
where the y-intercept is (0, -3).
To find its x-intercept, set y = 0 and solve for the value of x:
y = x - 3
0 = x - 3
Add 3 to both sides:
0 + 3 = x - 3 + 3
3 = x
Therefore, the x-intercept = (3, 0).
y = - 3/5x + 5
where the y-intercept is (0, 5).
Next, you could find a value of x that easily cancels out the fraction given by the slope (m) = -3/5. An input value of x = 5 cancels out the denominator of the slope:
y = - 3/5x + 5
y = - 3/5(5) + 5
y = -3 + 5
y = 2
Therefore, the other point that you could use to plot on the graph is (5, 2).
For y = x - 3, we'll use the line's intercepts: (0, -3) and (3, 0).
For y = - 3/5x + 5, we'll use (0, 5) and (5, 2).
Plotting these points on the graph will give us a solution of (5, 2), as it is the point where both lines intersect. Attached is a screenshot of the graphed lines.

Harper knows he is 50 yards from school. The map on his phone shows that the school is 34 inch from his current location.
How far is Harper from home, if the map shows the distance as 3 inches?
Answer:
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. We know that 1 yard is 36 inches, therefore, 50 yards expressed in inches is:
(50)(36)=1800in
2. If he is 50 yards from school and the map shows that the school is 34 inches from his current location, when it shows 3 inches the real distance is:
(1800)(3in)/24in=158.82
3. If you can to express it in yards:
158.82/36=4.41yd
Therefore, the answer is: 158.82 inches or 4.41 yards.

The question:
3. Two students created a list of steps for the following construction. Which student has steps in the correct order, and which does not? Explain.
The answer:
Student A is Wrong and student B is correct!
The work of the students:
You are given line AB and point C. Construct a line parallel to line AB that passes through point C.
Student A Steps:
Draw a line that intersects points B and C.
Draw a line through point C and point G.
Keep the compass at the same width, and place it on point C.
Keeping the compass at the same width, place it on point F.
Mark the intersection of the two arcs as point G.
Open the compass to the width between points D and E.
Place the compass on point B, and swing an arc that crosses line AB and line BC. Label the points D and E.
Swing an arc that crosses line BC, and label the point F.
Swing an arc that intersects the arc created from line BC at point C.
Student B steps:
Draw a line that intersects points B and C.
Place the compass on point B, and swing an arc that crosses line AB and line BC. Label the points D and E.
Keep the compass at the same width, and place it on point C.
Swing an arc that crosses line BC, and label the point F.
Open the compass to the width between points D and E.
Keeping the compass at the same width, place it on point F.
Swing an arc that intersects the arc created from line BC at point C.
Mark the intersection of the two arcs as point G.
Draw a line through point C and point G.
Student A is wrong and Student B is correct.
How?
Direction is saying to construct a line that passes through C The last step is enough to describe that A is wrong.Its saying to swing an arc(Should be line).On the other hand Student B has done correct By passing point through C and G it satisfies our required construction.
