Answer:
32
Step-by-step explanation:
As per what is given
- the product of 4 and a number decreased by 7 (4 times that number let us call it x, minus 7)
- equals 100, the equation formed equals 100
Form an equation;
4(x - 7) = 100
Solve using inverse operations;
4(x - 7) = 100
/4 /4
x - 7 = 25
+7 +7
x = 32
f is inversely proportional to √ g . When f = 8 , g = 25 Work out f when g = 16
f is inversely proportional to √ g . When f = 8 , g = 25 Work out f when g = 16
ANSWER :By question , f is inversely proportional to square root of g. In mathematical form ,
[tex]\implies f \propto \dfrac{1}{\sqrt g}[/tex]
Let k be constant . So that ,
[tex]\implies f =k \dfrac{1}{\sqrt g}[/tex]
When f = 8 , g is 25. So that ,
[tex]\implies 8= k\dfrac{1}{\sqrt {85}}[/tex]
[tex]\implies k = 8\sqrt{25} [/tex]
Hence the value of constant is 8√25.
So that when g is 16 ,
[tex]\implies f = 8\sqrt{25} \times 1/ \sqrt{16}\\\\\implies f = 8*5 / 4 \\\\\implies \boxed{ f = 10 } [/tex]
Hence the Value of f is 10 .
Write True or False. You can use the measures of the angles formed by two lines and a transversal to determine whether the two lines are parallel.
Answer:
I think that the answer is true (explanation might not be 100% accurate)
Step-by-step explanation:
Given that for 2 lines to be parallel, they have to never intersect at any point, meaning they both have to be straight and "facing" the same way. If either line has a tilt/angle of any sort, then they are not parallel.

Jack tool out a 6-year loan for $25,000 to purchase a boat at a 4.5% interest rate. If the interest is compounded monthly, what will he have paid total over the course of the loan?
Answer:
A = $32,732.58
A = P + I where
P (principal) = $25,000.00
I (interest) = $7,732.58
Step-by-step explanation:
Given data
Time= 6 years
Principal= $25,000
Rate= 4.5%
First, convert R as a percent to r as a decimal
r = R/100
r = 4.5/100
r = 0.045 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 25,000.00(1 + 0.045/12)^(12)(6)
A = 25,000.00(1 + 0.00375)^(72)
A = $32,732.58

Find area of the composite figure..
Answer:
627square inches
Step-by-step explanation:
Area of the composite figure.. = area of triangle + area of parallelogram
Since the triangle is an equilateral triangle;
Area of the triangle = r²sintheta
Area of the triangle = 18²sin60
Area of the triangle = 324sin60
Area of the triangle = 324(0.8860)
Area of the triangle = 280.584 square in
Area of the triangle = 281 square inches
Area of parallelogram = absintheta
Area of parallelogram = 20(20)sin60
Area of parallelogram = 400(0.8660)
Area of parallelogram = 346.4square inches
Area of parallelogram = 346 square inches
Area of the figure = 346 + 281
Area of the figure = 627square inches

The volume of a gas held at constant temperature varies inversely with the pressure of the gas. If the volume of the gas is 1200 cubic centimeters then the pressure is 200 millimeters of mercury, what is the volume when the pressure is 800 ml?
Answer:
300
Step-by-step explanation:
The volume of the gas varies inversely as the pressure
V= k/p
K= VP
= 1200×200
= 240,000
Therefore the volume when the pressure is 800
K= VP
240000= V×800
V= 240000/800
= 300
Hence the volume is 300 cubic centimeters
Biscuits are sold in in packs of 8. How many packs should you buy if you need 56 biscuits.
Answer:
7
Step-by-step explanation:
you just divide 8/56= 7
-----------------------------------------------------------------------------
Step 1:
Start by setting it up with the divisor 56 on the left side and the dividend 8 on the right side like this:
56⟌8
Step 2:
The divisor (56) goes into the first digit of the dividend (8), 0 time(s). Therefore, put 0 on top:
0
56⟌8
Step 3:
Multiply the divisor by the result in the previous step (56 x 0 = 0) and write that answer below the dividend.
0
56⟌8
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (8 - 0 = 8) and write the answer below.
0
56⟌8
-0
8
the answer to 8 divided by 56 calculated using Long Division is: 7
Solve for r. r - 76 = 9
Answer:
r=85
Step-by-step explanation:
r-76=9
add 76 to both sides
r=85
hope this is helpful
Answer: 85
Step-by-step explanation:
Since we're finding the placeholder of r and we're already subtracting, we need to add! What we need to do is add 76 + 9 which equals 85!
Hope this helps you! Good luck with your future work!

a dime is dropped from a building at 1.024 ft . if the equation for height as a function of time is h(t)=-16t^2+ initial height where is t is time in seconds and h(t) is height in feet, how many seconds will it take for the dime to hit the ground?
Answer:
The dime hits the ground after 8 sec.
Step-by-step explanation:
Set h(t) = -16t^2 + h(0) equal to 0: -16t^2 + 1,024 ft = 0, or:
16t^2 = 1,024 ft, or:
t^2 = 64 ft^2
Then t = +8 sec
The dime hits the ground after 8 sec.
