Answer:
-1/5 would be the exact form
Step-by-step explanation:
The decimal form would be -0.2
Answer:
[tex]\frac{\frac{4}{5} }{-2\frac{1}{2} }= \frac{\frac{4}{5} }{\frac{-5}{2} } = \frac{4}{5}\cdot\frac{-2}{5} = \frac{-8}{25}[/tex]

Simplify 3(tan ^2 0 - sec^2?0)
Answer:
Step-by-step explanation:
answer is -3 because tan^2 theta-sec^2 theta means -1 and when u multiply -1 and 3 u will get -3.
A trigonometric expression is given to us and we need to simplify it and find out the value.
Given Expression :-
[tex]\sf\implies 3(tan^2\theta - sec^2\theta )[/tex]
Using Identity :-
[tex]\sf\implies sec^2\theta - tan^2\theta =1[/tex]
So that ,
[tex]\sf\implies tan^2\theta -sec^2\theta = -1[/tex]
Substitute the value :-
[tex]\sf\implies 3(tan^2\theta - sec^2\theta ) \\\\\sf\implies 3 *(-1) =\boxed{\red{\sf -3}}[/tex]
Hence the required answer is -3 .

A) h(x) = 3x + 4
B) h(x) = -3x + 4
C) h(x) = 3x-4
D) h(x) = -3x+4
Answer:
B. h(x) = -3x + 4.
Step-by-step explanation:
I am assuming that the vertical shift is upwards,
A refection in the x axis gives -3x
Vertical shift upwards of 4 gives -3x + 4.
Find the quotient of 7/8 divided by 1/4 by using the procedure. Write your answer as a proper fraction, whole number or mixed number
Answer:
7/8 x 4/1
make 1/4 a reciprocal (basically just turning the fraction upside down)
then turn the division sign into a multiplication sign and multiply across:
7/8 x 4/1 = 28/8 = 3 4/8 = 3 1/2

Answer:
Step-by-step explanation:
use pythageran theorem
c=square root of a2+b2
but we are solving angle b
so
b2=c2-a2
b2=225-196
b2=29
b approximately = 5.39 Rounded up
Answer:
5.4
Step-by-step explanation:
c² = a² + b²
15² = 14² + b²
225 = 196 + b²
b² = 225 - 196
b² = 29
b = 5.4

A room measures 15 ft by 20 ft by 10 ft. If a basketball has a diameter of 9.6 inches, approximately how many basketballs will be needed to fill the room?
Answer:
10344.827586 basketballs
Step-by-step explanation:
A room measures 15 ft by 20 ft by 10 ft. If a basketball has a diameter of 9.6 inches, approximately how many basketballs will be needed to fill the room?
Step 1
We find the volume of the room
The room is rectangular in shape
Volume = Length × Width × Height
= 15ft × 20ft × 10ft
= 3000ft³
Step 2
Basket ball is spherical in shape
Volume of a sphere = 4/3πr³
Diameter = 9.6 inches
Radius = Diameter/2 = 9.6 /2 = 4.8 inches
Convert Radius from inches to ft
= 4.8inches/12
= 0.408333 feet
Volume of a sphere = 4/3 × π × 0.408333³
= 0.29 ft³
Step 3
3000 ÷ 0.29

Step-by-step explanation:
Daniel, Isabella, and Mia began their
homework at the same time.
Daniel finished his homework in 60 minutes.
Isabella finished her homework in 50% of
Daniel's time. Mia finished her homework in
150% of Daniel's time.
How long did Mia and Isabella each work?
Answer:
50% of 60 is 30.
100% of 60 is 60, plus 50% is 60+30, which gets you 90.

Arc PR = ___ degrees
===========================================================
Explanation:
Angle PAQ is 90 degrees as the square marker indicates. The adjacent angle RAQ is also 90 degrees.
So overall, central angle PAR is 90+90 = 180 degrees. Arc PQR is 180 degrees which is a semicircle.
How can you describe the effect of a dilation on coordinates using an algebraic representation?
Answer:
When a dilation in the coordinate plane has the origin as the center of dilation, you can find points on the dilated image by multiplying the x- and y-coordinates of the original figure by the scale factor.
Step-by-step explanation:
If events A and B are independent, P(A) = 0.62, and P(
BA) = 0.93, what is P(B)?
O 0.41
O 0.93
O None of the other answers are correct
O 0.58
O 0.67
Answer:
Step-by-step explanation:
you’re given A=0.62 and B/A=0.93
you’re solving for B
substitute your A value of 0.62
B/0.62=0.93
same as B/0.62=0.93/1
now cross multiply
B= 0.62x0.93
B=0.5766
B=0.58

4x - 3
0 4x - 1
O 44 - 4
4 + x - 1
2x - 4 + 2x
O x - x + 2x + 4
Answer:
2x - 4 + 2x
Step-by-step explanation:
4 ( x - 1 )
= 4 ( x ) - 4 ( 1 )
= 4x - 4
= 2x + 2x - 4
= 2x - 4 + 2x

Kathy has a circular hot tub in her backyard with a
radius of 5.5 feet. She wants to place a decorative
border around the circumference of the hot tub. If the
border costs $6.70 per foot, how much will the border
for the hot tub cost? Type in your answer without the '$'
sign.
Answer:
$231.42
Step-by-step explanation:
Find the tub radius. It is C = 2πr, which here is C = 6.28(5.5 ft ) = 34.54 ft.
The border costs $6.70/ft. Multiply $6.70/ft by 34.54 ft:
($6.70/ft)(34.54 ft) = $231.42

The formula = () − applies to the demand of a product, where q is the number of units and P is the price of one unit. How many units will be demanded if the price is Rs. 18.00?
Answer:
4320 units quantities were demanded
Step-by-step explanation:
Given:
[tex]p = 90 (5) - \frac{q}{10}[/tex]
Required:
The units demanded when price = 18.00
This implies that:
[tex]p = 18.00[/tex]
So, we have:
[tex]p = 90 (5) - \frac{q}{10}[/tex]
[tex]18.00 = 90(5) - \frac{q}{10}[/tex]
Open bracket
[tex]18.00 = 450 - \frac{q}{10}[/tex]
Collect like terms
[tex]\frac{q}{10} = 450 - 18.00[/tex]
[tex]\frac{q}{10} = 432[/tex]
Solve for q
[tex]q = 432 *10[/tex]
[tex]q = 4320[/tex]

Question 1 options:
A 30°-60°-90° triangle has a shorter leg with a length of 14 cm. The hypotenuse of the triangle is ___ cm
From now on, remember that the smallest side in a triangle is always facing the smallest angle of the triangle.
_________________________________
The question told us that the shorter leg has a measure of 14 in which it is tha smallest side of the triangle thus 14 is the facing side to the 30 degrees angle .
As we know, in a right-angled triangle, the facing side to the angle of 30 degrees has half measure of hypotenuse. So :
1/2 × hypotenuse = 14
Multiply both sides by 2
hypotenuse = 28
Use a formula to find the amount of wrapping paper you need to wrap a gift in the cylindrical box shown. You need to cover the top, bottom, and all the way around the box. Use 3.14 for .
Answer:
Total wrapping paper need = 960.84 inch²
Step-by-step explanation:
Given:
Height of cylinder box = 8 inch
Radius of cylinder box = 9 inch
Find:
Total wrapping paper need
Computation:
Total wrapping paper need = Total surface area of cylinder
Total surface area of cylinder = 2πr(h + r)
Total wrapping paper need = 2[3.14][9][8+9]
Total wrapping paper need = 2[3.14][9][17]
Total wrapping paper need = [6.28][9][17]
Total wrapping paper need = [56.52][17]
Total wrapping paper need = 960.84 inch²
if p (n,3)=1320what is n
Answer:
n=12
Step-by-step explanation:
lol we meet again
just use the permutation formula for this one.
n!/(n-3)!=1320
[n×(n-1)×(n-2)×(n-3)!]/(n-3)!=1320
n(n-1)(n-2)=1320
(n²-n)(n-2)=1320
n³-3n²+2n-1320=0
n=12
