Answer:
6. He had Rs728.
7. There are 1875 pupils in the school.
Step-by-step explanation:
6.
He started with x amount of money.
He spent 1/4 of x. x - (1/4)x = (4/4)x - (1/4)x = (3/4)x
After buying the lottery tickets, he had (3/4)x left.
Then he spent 2/7 of the remainder on scratch cards.
He spent 2/7 of (3/4)x on scratch cards. Since he spent
2/7 of the reminder on scratch cards, he has 5/7 of the reminder left.
5/7 * (3/4)x = (15/28)x
He has (15/28)x left. He has Rs390 left.
(15/28)x = 390
15x = 390 * 28
15x = 10920
x = 728
Answer: He had Rs728.
7.
8/15 of the pupils are girls.
1 - 8/15 = 15/15 - 8/15 = 7/15
7/15 of the pupils are boys.
Let x = total number of pupils in the school
(8/15)x = (7/15)x + 125
Multiply both sides by 15.
8x = 7x + 1875
x = 1875
Answer: There are 1875 pupils in the school.
Parallelogram L M N O is shown. Angle M is (3 x minus 55) degrees, angle N is (5 y) degrees, and angle O is (2 x) degrees. In parallelogram LMNO, what are the values of x and y? x = 11, y = 14 x = 11, y = 25 x = 55, y = 14 x = 55, y = 25
Answer:
The correct option is:
x=55 , y = 14
Step-by-step explanation:
We know about the following features of a parallelogram:
Opposite sides are parallelOpposite side have equal lengthOpposite angles are equalSum of all angles is 360°For the parallelogram LMNO, <L and <N are opposite angles, <M and <O are opposite angles.
Are opposite angles are equal.
<M = <O
3x - 55 = 2x
3x - 2x = 55
x = 55
So
<M = 3x - 55 = 110°
<O = 2x = 110°
We know that the sum of angles is 360°
<L + <M + <N + <O = 360°
<L + <N + 110° + 110° = 360°
As <L and <N are opposite, both are equal. hence <L = <M = 5y
5y + 5y + 220° = 360°
10y + 220° = 360°
y = 14
Answer:
x = 55, y = 14
Step-by-step explain
it is X = 55, y = 14

Determine the slope of the line through the given points. If the slope is undefined, so state. (3,2) and (6,11)
Answer:
The slope is 3
Step-by-step explanation:
We can find the slope by using
m = (y2-y1)/(x2-x1)
= (11 -2)/(6-3)
= 9/3
= 3
Answer:
y = 3x – 7
Step-by-step explanation:
[tex]\frac{y_{2} }{x_{2} } -\frac{y_{1} }{x_{1} }[/tex]
[tex]\frac{11}{6} -\frac{2}{3} =[/tex]
[tex]\frac{9}{3} =[/tex]
3
The y-intercept of the slope is -7 if you graph it. So from the equation: y = mx + b, we get y = 3x - 7. (m is slope, b is y-intercept)

A building block is made by taking a 6 cm by 4 cm by 2 cm block and removing four cubes from the center of the block. The volume of the final block is 44 cm3.
A rectangular prism with a length of 6 centimeters, width of 4 centimeters, and height of 2 centimeters. 4 blocks are removed from the block with dimensions 6 by 4 by 2 centimeters.
What is the length of one side of one cube that was removed?
1 cm
1.5 cm
2 cm
2.5 cm
Answer:
(A)1 cm
Step-by-step explanation:
Volume of the Prism before the cubes were removed[tex]=6 X 4 X 2 = 48$ cm^3[/tex]
Volume of the Prism after the 4 cubes were removed[tex]=44$ cm^3[/tex]
Therefore, Volume of the 4 cubes
[tex]=48cm^3-44cm^3\\=4cm^3[/tex]
If Volume of the 4 cubes = 4 cubic centimeter
Volume of 1 cube =4/4 =1 cubic centimeterVolume of a cube of side length s[tex]=s^3[/tex]
Therefore:
[tex]s^3=1 cm^3\\$Side Length, s=1 cm[/tex]
The side length of 1 cube that was removed is 1 cm.
The correct option is A.

If m∠ABC = 53° and m∠ECD = 40°, which statement explains whether the AA similarity postulate can be used to determine whether ΔBAC ~ ΔEDC?
Yes, the AA similarity postulate can be used because a reflection over line f will establish that ∠ABC ≅ ∠DEC.
Yes, the AA similarity postulate can be used because a reflection over line f will establish that ≅ .
No, the AA similarity postulate cannot be used because a reflection over line f will establish that ∠ABC and ∠DEC are not congruent.
No, the AA similarity postulate cannot be used because a reflection over line f will establish that and are not congruent.
Similar triangles may or may not be congruent.
The true statement is (c) No, the AA similarity postulate cannot be used because a reflection over line f will establish that ∠ABC and ∠DEC are not congruent.
The given parameters are:
[tex]\mathbf{\angle ABC = 53}[/tex]
[tex]\mathbf{\angle ECD = 40}[/tex]
From the image of the triangles (see attachment);
The triangles are similar if:
[tex]\mathbf{\angle ABC + \angle ECD = 90}[/tex]
Substitute the given values
[tex]\mathbf{53 + 40 = 90}[/tex]
[tex]\mathbf{93 = 90}[/tex]
The above equation is not true, because:
[tex]\mathbf{93 \ne 90}[/tex]
Hence, the triangles are not similar by AA

Each letter in the expression shown to the right represents a digit other than zero. Different letters represent different digits and the same letter always represents the same digit. What is the smallest whole number that can be the value of this expression?
Answer:
The smallest whole number that can be the value of the expression is 2
Step-by-step explanation:
Given that the letters represent different digits, to get the smallest whole number value for the expression we have;
[tex]\dfrac{K \times A \times N \times G \times A \times R \times O \times O}{G \times A \times M \times E}[/tex]
The letters G and A cancel out from the numerator and the denominator to give;
[tex]\dfrac{K \times A \times N \times R \times O \times O}{M \times E}[/tex]
Therefore, the smallest whole number can be from 2 and above as the product of six digits is more than one times the product of two digits
If we put
K = 2, A = 3, N = 4, R = 6, O = 1, M = 9, and E = 8, we have;
[tex]\dfrac{2 \times 3 \times 4 \times 6 \times 1 \times 1}{9 \times 8} = \dfrac{144}{72} =2[/tex]
Therefore, the smallest whole number that can be the value of the expression = 2.

Reset
Next
Answer:
The chart type described is the OHLC chart.
Step-by-step explanation:
An OHLC chart is a kind of bar-chart that displays open, high, low, and closing prices for each period. OHLC charts are beneficial since they demonstrates the four major data values over a period, with the closing price being reflected as the most significant by traders.
The chart type is valuable since it can represent increasing or decreasing movement. When the open and close are far-apart it represents strong movement, and when the open and close are close together it represents wavering or weak movement. The high and low displays the full price range of the period, useful in evaluating instability.
Thus, the chart type described is the OHLC chart.

Standard form of the equation that goes through (3, -1) with a slope of -1, please!
Answer:
x+y=2
Step-by-step explanation:
Standard Form: ax+by=c
For most convenience start with slope-intercept form: y=mx+b
1. -1 = -1(3)+b - solve for b
b=2
y= -1x+2 (slope-intercept form)
2. Now convert to standard form
Add 1x to both sides:
1x+y=2
(SAT Prep) In the given figure, the reflex angle ∠DOB has measure of 3.5y while the measure of ∠AOD is y. Find the measure of the non-reflex ∠DOB in degrees.
Answer:
252°
Step-by-step explanation:
In the figure attached, the diagram is shown. There, we can see that
∠DOB = ∠AOD + ∠AOC + ∠COB
Replacing with the equivalences: ∠DOB has a measure of 3.5y, the measure of ∠AOD is y, and ∠AOC + ∠COB measure 180°, we get:
3.5y = y + 180°
3.5y - y = 180°
2.5y = 180°
y = 180°/2.5
y = 72°
Therefore, ∠DOB = 3.5*72° = 252°
Answer:
108 degrees
Step-by-step explanation:
m∠DOB=m∠AOD+m∠AOC+m∠COB And then we substitute, m∠DOB=3.5y, m∠AOD=y, m∠AOC+m∠COB=180 degrees. So the equation will then be 3.5y=y+180 degrees
y= 72
m∠DOB=3.5 x 72 m∠DOB=252 degrees, this is the reflex angle.
360-252=108 degrees, the non-reflex m∠DOB= 108 degrees
