The measure of angle D is 47 degrees and the measure of angle C is 57 degrees. What is the
measure of angle A?
47
57
76
104
Answers
Answer:
D. 104º
Step-by-step explanation:
So the inside of a triangle is equal to 180º and we already know two of the angles.
D = 47º
C = 57º
47 + 57 = 104
To solve angles A and B, we know that a straight line is 180º and we can figure out the angle of B because now all we have to do is subtract 104 from 180.
180 - 104 = 76, B = 76º
Because we know that a straight line is 180º and we already have the measure of angle B, all we have to do now is subtract 76 from 180.
180 - 76 = 104º

Saiful deposits a sum of RM 5000 in a bank with interest rate of 4% per annum. What is the interest
earned by Saiful after 3 months ?
Answers
Answer:
Saiful has earned RM 50 after 3 months.
Step-by-step explanation:
We are given the following:
x = 5000
y = 4% per 12 months (annually)
[Convert 4%/1 yr to three months]
Because 1 year = 12 months = 4% then:
3 months is 25% of 12 months, so find 25% of 4%.
25% of 4% is 1%
y = 1%
[Multiply x by y]
x * y = 5000*1% = 5050
[Subtract 5050 by the original, 5000]
5050 - 5000 = 50
Saiful has earned RM 50 after 3 months.

Find the slope and y-intercept of the line whose equation is given.
y= - 7x-9
Determine the slope. Select the correct choice below and fill in any answer boxe
A. m=
(Type an integer or a fraction.)
OB. The slope is undefined.
Answers
Answer:
Slope = -7
y-intercept = -9
Step-by-step explanation:
The slope formula is y = mx + b where m is the slope value and b is the y-intercept value. In this case, since both values have a negative sign in front of them, they are both negative.
y = mx + b
y = -7x - 9
m = -7 which is the slope
b = -9 which is the y -intercept

You gotta find the pretty points on the line of the linear function. Then you have to find the slope (rise over run) with those pretty points. Then you have to use a coordinate (I used 6,4) to find the y intercept. Then you solve the equation, by plugging in all the numbers :) hope this helps.

Answer:
2 2 /5 = 2.4 = 240 %
Step-by-step explanation:
The number 1 is the same as 1.00 and is the same as 100%.
The number 2, therefore, is the same as 2.00 and the same as 200%
2 /5 can be converted into a decimal by seeing that 2 /5 = 4 /10 . 4 /10 , spoken out loud, is "four tenths" and shows that the decimal is
0.4 . And 0.4 is the same as 40%. Which means that 2 2 /5 = 2.4= 240 %

Because there was 30 question, and she got 30 marks
30 - 30 = 0
there are 90 possible marks. since she got 30, i divided 30/90. which resulted in 0.333333. i think multiplied that by 30 to get the number of correct answers which was 10, leaving 20 incorrect

- 11 - 10 3/8
11+ 10 3/8
21 3/8
Answers
Answer:
-3.8 - (7.2-10 3/8)
-3.8+(-7.2+10 3/8) this is the error, it's positive 10 3/8, not negative, then you should solve what's in the parentheses first
I simplified 10 3/8 into 83/8 and then 10.375
-3.8+(-7.2 + 10.375)
-3.8+ 3.175 = -0.625

Find the value of x if C is the midpoint of line segment AB, AC=4x+5, and
AB=78?
Answers
Answer:
x = 8.5
Step-by-step explanation:
AC + CB = AB
As C is the midpoint AC = CB = 4X + 5
AC + CB = AB
4x + 5 + 4x + 5 = 78
4x + 4x + 5 + 5 = 78 {Combine like terms}
8x + 10 = 78 {Subtract 10 from both sides}
8x = 78 - 10
8x = 68
x = 68/8
x = 8.5

Simipified the exprestion -1.7+(-6.3).On the test when maureen simipified the exression she got -4.6. What mistake did maureen likley make when she simipified the question
Answers
Answer:
Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7
Step-by-step explanation:
-1.7 + (-6.3)
Correct simplification
-1.7 + (-6.3)
Open parenthesis
= - 1.7 - 6.3
= -8
NOTE:
- * + = -
- * - = +
+ * - = -
+ * + = +
Maureen's simplification
-1.7 + (-6.3)
= 1.7 - 6.3
= -4.6
Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7
