How much will she save?
Answer:
She will save $3.60
Step-by-step explanation:
10% of 24= 2.4
5% of 24 = 1.2
2.4 + 1.2= 3.6
This means she is saving $3.60 because 15% of $24 is $3.60! :)
Jana save $3.6 to buy a shirt.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
The shirt is normally $24, but today it is on sale for 15% off.
Now,
Since, The shirt is normally $24, but today it is on sale for 15% off.
Hence, The save money = 15% of 24
= 15/100 × 24

Mr. Beck has 5 brown socks, 1 pair of green socks, and 4 pairs of blue socks in his sock drawer. If he randomly chooses one pair from the drawer, what is the probability that he will choose a blue pair of socks?
a. 1/2
b. 1/10
c. 3/5
d. 2/5
Answer:
D. 2/5
Step-by-step explanation:
First, find the total number of sock pairs in his drawer:
5 + 1 + 4
= 10
Since there are 4 pairs of blue socks, the probability that he will choose a blue pair of socks is 4/10.
This can be simplified by dividing each number by 2.
Simplified, the probability is 2/5.
So, the correct answer is D. 2/5

Answer:
x = 15
Step-by-step explanation:
Chords equidistant from the circle center subtend the same arc measure. The sum of the three arcs of the circle is 360°, so you can write the relation ...
2(10x -23)° +106° = 360°
2(10x -23) = 254 . . . . . . . . divide by °, subtract 106
10x -23 = 127 . . . . . . . . . divide by 2

In triangle MNO the measure of angle O =90 degrees the measure of angle M =66 degrees and NO = 60 feet Find the length of MN to the nearest tenth of a foot
Answer:
Length of MN = 65.68 feet (Approx.)
Step-by-step explanation:
Given:
Height of NO = 60 feet
Angle ∠M = 66°
Find:
The length of MN
Computation:
Given triangle is a right angled triangle
So,
NO is a perpendicular
MN is hypotenuse
Using trigonometry functions
Sin θ = Perpendicular / Hypotenuse
Sin 66 = NO / MN
0.9135 = 60 / Length of MN
Length of MN = 60 / 0.9135
Length of MN = 65.68 feet (Approx.)
Answer: approximately 65.6782 = 65.7
