find the value of X round to the nearest tenth
Answers
Given:
In a right angle triangle triangle, the length of hypotenuse = 47 units.
One of the acute angle = 17°.
Opposite side of the given angle = X
To find:
The value of X. Round to the nearest tenth.
Solution:
In a right angle triangle,
[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]
A right triangle is crated with the help of dotted lines. In this triangle,
[tex]\sin (17^\circ)=\dfrac{X}{47}[/tex]
[tex]0.2923717=\dfrac{X}{47}[/tex]
Multiply both sides by 47.
[tex]0.2923717\times 47=X[/tex]
[tex]13.74147=X[/tex]
[tex]X\approx 13.7[/tex]
Therefore, the approximate value of X is 13.7 units.

Find the length of A.
Answers
Answer:
5
Step-by-step explanation:
13^2=169
12^2=144
169-144=25
Root 25 is 5
use Pythagorean theorem: a^2+b^2=c^2
plug in the values
x^2+12^2=13^2
Move the 12^2 to the other side
x^2=13^2-12^2
x^2=25
Take the square root from both sides
x=5
Dennis read 30% of his book on Tuesday and of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?
Answers
Answer:
1/2x
Step-by-step explanation:
Dennis read 30% of his book on Tuesday and 1/5 of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?
Total pages of the book = x
Tuesday = 30%
= (30/100)x
= 3/10x
Wednesday = 1/5x
3/10x + 1/5x
= 3x+2x/10
= 5/10x
= 1/2x
what fractional part of the book did he have left to read after Wednesday
= x - 1/2x
= 2x-x/2
= x/2
= 1/2x

What is the final amount if 784 is decreased by 1% followed by a 4% increase?
Give your answer rounded to 2 D
Answers
Answer:
807.21
Step-by-step explanation:
for the 1 % decrease
1/100 × 784 = 7.84
784 - 7.84 = 776.16
then 4% increase
4/100 × 776.16 = 31.0464
776.16 + 31.0464= 807.2064

Peter is folding brochures for his Dad's new company. After 1 hour, he has 330 brochures left to fold. After 4 hours, he only has 90 brochures left to fold.
(From the above statements you should be able to create two ordered pairs. I will create one for you..... (1,330). Now you create the other ordered pair and continue with the problem.)
Write an equation in slope-intercept form, y=mx+b, that represents the number of brochures Peter has left to fold, , after a given number of hours, x.
Answers
Answer:
y = -80x + 410
Step-by-step explanation:
(1,330) is the first point, the other point is (4,90)
m = y2 - y1/x2 - x1
m = 90 - 330/4 - 1
m = -240/3
m = -80/1
m = -80
y - y1 = m(x - x1)
y - 330 = -80(x - 1)
y - 330 = -80x + 80
y = -80x + 80 + 330
y = -80x + 410

What is the surface area?
Answers
Answer:
0.5 X 15 X 20 = 150m squared
150 X 2 = 300m squared (that's the two triangles done)
25 x 7 = 175m squared (front)
15 X 7 = 105m squared (base)
20 X 7 = 140m squared (back)
now add them all together
300 + 175 + 105 + 140 = 720
SA = 720cm squared
Answer:How do u find the surface area of a cube?
To determine the surface area of a cube, calculate the area of one of the square sides, then multiply by 6 because there are 6 sides. This is the same as solving using the formula SA = 6s2. If you are given the surface area, you can determine the side length by working backwards.

Sonya had 20 dollars to spend on 3 gifts. She spent 8 1 4 dollars on gift A and 4 4 5 dollars on gift B. How much money did she have left for gift C?
Answers
Answer:
6 19/20 dollars
Step-by-step explanation:
Sonya had 20 dollars to spend on 3 gifts.
She spent 8 1 4 dollars on gift A and 4 4 5 dollars on gift B.
Gift A + Gift B + Gift C = $20
Gift C = $20 - (Gift A + Gift B)
Gift A = $8 1/4
Gift B = $4 4/5
Hence:
The amount she had left for gift C is :
Gift C = $20 - ($8 1/4 + $ 4 4/5)
Gift C = $20 - $13 1/20
Gift C = $ 6 19/20
A shoe store buys a shipment of nike shoes that cost $70 each to the purchases. They want to markup their prices for the customers by 30%. How much would the customer pay for a pair of nikes
Answers
Given :
A shoe store buys a shipment of Nike shoes that cost $70 each to the purchases.
They want to markup their prices for the customers by 30%.
To Find :
How much would the customer pay for a pair of Nikes.
Solution :
C.P = $70 .
It is given that selling price is 30% more than the S.P.
So, S.P = C.P + C.P×0.30
S.P = C.P×1.30
S.P = 70×1.30
S.P = $91.
Therefore, the customer would pay $91 for a pair.

(15y + 6)°, and m2T = (2x + 6),
Answers
9514 1404 393
Answer:
m∠W = m∠S = 126°
m∠E = m∠T = 54°
x = 24
y = 8
Step-by-step explanation:
Opposite angles of a parallelogram are congruent, so we have ...
∠E = ∠T
3x -18 = 2x +6
x = 24 . . . . . . . . . add 18-2x
Then the measure of these angles (in degrees) is ...
∠E = ∠T = 2x+6 = 2(24) +6 = 54
__
The adjacent angle W is supplementary to either of these:
∠W = 180° -∠E
15y +6 = 180 -54
15y = 120
y = 8
∠W = ∠S = 126°
Answer:
y = 8
Angle S= 126°

Use one or more exponents to write the expression.
