Gold and silver are mixed in the ratio 7:4.if 36gm of silver is used.How many gold is used
Answer:
63gm
Step-by-step explanation:
7 gold : 4 silver
It gives you 36 silver.
to get from 4 silver to 36 silver you multiply by 9.
you multiply the gold by the same amount 9.
7*9= 63

What is the slope of a line that is perpendicular
to a line with a slope of -⅓
Answer:
3/1, or 3
Step-by-step explanation:
When you have a perpendicular line, if it is a negative, you take away the negative, and if it is a fraction, you turn it upside down. 1/3 becomes 3/1.
The map shows the location J of Jose's house, the location of Tyrell's house, and the
location Fof the football field. Jose is going to Tyrell's house and then the two of them are
going to the football field for practice. How far did Jose travel to football practice?
Using distance between two points, it is found that Jose traveled 25 units of length to football practice.
The distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is given by:
[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
First, Jose goes from his house, at (-6,8), to Tyrell's house, at (6,8), thus:
[tex]D_1 = \sqrt{(6 - (-6))^2 + (8 - 8)^2} = \sqrt{12^2} = 12[/tex]
Then, he goes from Tyrell's house, at (6,8), to the football field, at (6, -5), thus:
[tex]D_2 = \sqrt{(6 - 6)^2 + (-5 - 8)^2} = \sqrt{13^2} = 13[/tex]
The total distance is:
[tex]D = D_1 + D_2 = 12 + 13 = 25[/tex]
Jose traveled 25 units of length to football practice.

Step-by-step explanation:
that is really, really simple.
h(-3) means that we put the argument (-3) into the formula of the function everywhere where there is x.
h(x) = -3x - 10
so,
h(-3) = -3×-3 - 10 = 9 - 10 = -1
Answer:
-1
Step-by-step explanation:
h(x) = -3x - 10
h(-3) means to replace the x in the problem with the value of -3 and
solve.
h(-3) = -3(-3) - 10
h(-3) = 9 - 10
h(3) = -1
Robin Bolton earns a monthly gross salary of 3,280 as a medical assistant she is considering a new position as a medical office manager which would pay 14.90 an hour with time and a half per hour for all 40 per week how many of overtime per week would robin need to work to earn the same amount as her current job
The number of overtime hours Bolton will need at his new position in other to make the same monthly income ls 10 hours per week.
Monthly gross = 3,280 Weekly gross = 3280 / 4 = 820New position :
Pay per hour = 14.90Overtime = 1.5(14.90) = 22.35Let the number of overtime hours required weekly = t
Hence,
(14.90 × 40) + 22.35t = 820
596 + 22.35t = 820
22.35t = 820 - 596
22.35t = 224
t = 224 / 22.35
t = 10
Therefore, he'll need 10 hours of overtime.

The required simplified value of the given expression is 210
As mentioned in the question,
To raise the fraction to its highest terms by supplying the missing numerator.7/8=x/240.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
according to the question,

What is the sum of the roots of the equation 2 x^2 + 5 x − 3 = 0?
a)-3.5
b)-2.5
C)-1.5
D)2.5
Answer:
B) -2.5
Step-by-step explanation:
2x^2 + 5x -3 = 0
(2x - 1)(x + 3) = 0
2x - 1 = 0; 2x = 1, so x = 1/2 = ROOT 1
x + 3 = 0, so x = -3 = ROOT 2
Now add the roots: -3 + 1/2 = - 2 1/2, so the answer is B.

Find the area I will make you Brainliest (show working) the bottom number is 8 cm where it says liveworksheets
Answer:
228cm^2
Step-by-step explanation:
Multiply 18cm by 10cm:
18 x 10 = 180cm^2
So we have the area of the biggest/top part: 180cm^2
For the bottom part:
You've said the length of the bottom side is 8cm.
We know the length of the biggest side: 24cm. And we know the length of the opposite side: 18cm. So, to find the length of the missing side, it's simple subtraction:
24cm - 18cm = 6cm
So now we have lengths for 2 sides: 8cm and 6cm.
Multiply these to give the area:
8cm * 6cm = 48cm^2
Add these areas of both shapes together to give total area:
180cm^2 + 48cm^2 = 228cm^2

X = 40°
Step-by-step explanation:
The triangle on the left is an Isosceles triangle which means it has 2 equal sides. So, to find the third angle, u have to minus 180 and both the base angles.
180° - 35° - 35°
= 110°
Then, minus 180 with the right triangle base bcs a straight line is 180°.
So,
180 - 110
= 70°
Now u got the right triangle base which is also an isosceles triangle so both angles are 70°
Now to find the third angle, minus 180 to both the base angles
180 - 70 - 70
= 40°
And that's your answer.
