A cricket bat is bought for $400. Later, it is sold with a loss of 15%. How much is the cricket bat sold for? =
After selling the cricket bat, how much money has been lost? Give your answer to two decimal places because it is a currency.=
Answers
400 minus 60 is 384
so The bat was sold for 384 but 384 in currency is 329.94
Answer:
$340.00
Step-by-step explanation:
What I like to do first is find 10% of the number.
So 10% of 400 would be $40.
Then find half (5%) of the 10% ($40), which would be $20.
Add the $40 + $20 to get $60.
Then take $400 and subtract $60,
which gives you $340.00

∠ 5 = 84°
Step-by-step explanation:
Complementary angles sum to 90° , then
∠ 5 + ∠ 6 = 90° , that is
∠ 5 + 6° = 90° ( subtract 6° from both sides )
∠ 5 = 84°

Answers
Answer:
The slope of line b would be -1/7.
Step-by-step explanation:
This happens because if you have the slope of any line and are trying to find the perpendicular line to said line, the slope of the perpendicular line will always be the opposite reciprocal of the original slope.
Then, all you need to do is find some points and graph the lines.

Which of the following rational number between 3/7 and 7/8 ?
13/56
19/56
27/56
53/56
Answers
Answer:
Step-by-step explanation:
There are two ways to do this. You could use your calculator to find out the decimal numbers that are equivalent to the two given fractions. Then check which one of the givens falls between these two numbers. I wouldn't do it that way -- not when you are told that the answer has 56 as the denominator. So ...
The best way to do it is to change the two givens so that they have a denominator of 56
3/7 = 3*8/7*8 = 24 / 56
7*7 / 7*8 = 49 / 46
So you need a number that is between 49 and 24
There is only one 27 / 56
2(3w-6)=5w+8
asap plz
Answers
Answer:
w = 20
Step-by-step explanation:
2 (3w - 6) = 5w + 8
distribute the 2
6w - 12 = 5w + 8
subtract 5w from both sides
w - 12 = 8
add 12 to both sides
w = 20
Answer:
The value of w is 20.
Step-by-step explanation:
Solution :
[tex]{\longmapsto{\tt{2(3w - 6)=5w + 8}}}[/tex]
[tex]{\longmapsto{\tt{(3w \times 2 )- (6 \times 2)=5w + 8}}}[/tex]
[tex]{\longmapsto{\tt{(6w)- (12)=5w + 8}}}[/tex]
[tex]{\longmapsto{\tt{6w - 12=5w + 8}}}[/tex]
[tex]{\longmapsto{\tt{6w - 5w = 8 + 12}}}[/tex]
[tex]{\longmapsto{\tt{w = 20}}}[/tex]
Hence, the value of w is 20.

Step-by-step explanation:
The volume of the bar is ...
V = LWH
V = (5 cm)(3 cm)(1 cm) = 15 cm³
1 dL = 100 cm³, so this volume is ...
(15 cm³)(1 dL)/(100 cm³) = 0.15 dL
The bar will displace 0.15 deciliters.
