Answer:
$120
Step-by-step explanation:
Step 1: Find how much he had in total. One way of doing that is setting up a fraction, then solve
[tex]\frac{76\%\:}{380}=\frac{100\%\:}{x}[/tex]
[tex]76\% =\frac{19}{25}[/tex]
[tex]100 =1[/tex]
Cross Multiply
[tex]\frac{19}{25}x=380\cdot \:1[/tex]
SImplify
[tex]\frac{19}{25}x=380[/tex]
Multiply both sides by 25
[tex]\frac{19}{25}x\cdot \:25=380\cdot \:25[/tex]
Simplify
[tex]19x=9500[/tex]
Divide both sides by 19
[tex]\frac{19x}{19}=\frac{9500}{19}[/tex]
Simplify
[tex]x=500[/tex]
That means he had a total of $500 in his account.
Step 2: Subtract the amount used from the total
[tex]500 - 380\\\\= 120[/tex]
Therefore, $120 is left in Travis' savings account.Answer:
$120
Step-by-step explanation:
Before the purchase, the amount of money in the account was x.
76% of the amount of money in the account is $380.
We write the above statement as an equation and solve for x, the original amount of money in the account.
76% of x = 380
0.76x = 380
Divide both sides by 0.76
0.76x/0.76 = 380/0.76
x = 500
He had $500 in his account.
He spent $380.
$500 - $380 = $120
He has $120 left in the account.
Answer: $120
What is the measure of the angle labeled n?
Answer:
B. 74°
Step-by-step explanation:
n and 106° are same-side interior angles.
Same side interior angles are also supplementary angles, meaning they add to 180°.
n+106=180
n=74°
Of 118 randomly selected adults, 29% said that they had high blood pressure. Find the 95% confidence interval for the proportion of all adults that have high blood pressure. State the interval and write a sentence explaining the information in the interval in the context of the problem.
Answer:
(0.208 ; 0.372)
Step-by-step explanation:
phat = 29% = 0.29
Sample size, n = 118
The confidence interval :
phat ± margin of error
Margin of Error = Zcritical * √phat(1 -phat) / n
Zcritical at 95% = 1.96
Margin of Error = 1.96 * √0.29(0.71) / 118
Margin of error = 1.96 * 0.0417721
Margin of Error = 0.0818734
Confidence interval :
Lower boundary : 0.29 - 0.0818734 = 0.208
Upper boundary = 0.29 + 0.0818734 = 0.372
(0.208 ; 0.372)
We can be 95% confident that the proportion of adults with high blood pressure is lies within the interval (0.208 ; 0.372)
The area of the rectangle is 65 yd^2,and the length of the rectangle is 3 yd less than twice the width. Find the dimensions of the rectangle
Answer: Length = 10cm
Width = 6.5cm
Step-by-step explanation:
Let the width of the rectangle be represented by x.
Therefore, the length of the rectangle will be: = (2 × x) - 3 = 2x - 3
Therefore area of a rectangle = length × width
x(2x - 3) = 65
2x² - 3x = 65
2x² - 3x - 65 = 0
2x² + 10x - 13x - 65 = 0
2x(x + 5) - 13(x + 5) = 0
(2x - 13)(x + 5) = 0
2x - 13 = 0
2x = 13
x = 13/2
x = 6.5
Width = 6.5cm
Length = 2x - 3
= 2(6.5) - 3
= 13 - 3
= 10cm
Therefore, the length of the rectangle is 10cm and the width is 6.5cm.

Jika harga sebuah martil adalah 10 kali harga paku, dan harga satu lusin paku adalah Rp 1.200,-, berapa harga martil tersebut?
Menjawab:
1000
Penjelasan langkah demi langkah:
Mengingat bahwa :
Harga palu 10 potong harga paku;
Harga selusin paku = 1200
1 lusin = 12
Jadi harga paku adalah:
1200/12
= 100
Makanya, harga paku = 100
Jadi, harga palu adalah:
10 kali lipat, harga paku
10 * 100 = 1000

Answer:
9.32
10.116
Step-by-step explanation:
each corner is a right corner so were going to subtract 58 from 90 because all right corners are 90 degrees
90-58=32 answer A 32
after that we know that all triangles have to equal 180 so now we subtract
180-58=122 122-58=64
we subtract 58 two times because we have 2 of the same angles
next we know that the smaller angle is 32 so now we subtract again
180-32=148 148-32=116 so y is 116
If you have 0.2 moles of NaCl in 0.5 L of solution, what is the molarity? (Round answers to the nearest hundredth)
Answer:
Molarity = 0.4 moles per Liter
Step-by-step explanation:
If you have 0.2 moles of NaCl in 0.5 L of solution, what is the molarity? (Round answers to the nearest hundredth)
The formula formula Molarity
= n/v
Where n = number of moles
v = volume in liters
Hence
Molarity = 0.2 moles/0.5L
= 0.4 moles per Liter

Q1. Three types of coffee beans, A, B and C, are blended in the ratio 3: 5:7 to make a bag of coffee
powder. Given that the bag contains 45 kg of coffee powder, find the mass coffee beans A in the
mixture?
Answer:
Mass of coffee A beans = 9 kg
Step-by-step explanation:
Coffee A = 3
Coffee B = 5
Coffee C = 7
A : B : C = 3 : 5 : 7
Total ratio = 15
Total mass of the bag = 45 kg
find the mass coffee beans A in the mixture?
Mass of coffee A beans = ratio of coffee A / total ratio × total mass of the bag
= 3/15 × 45
= 1/5 × 45
= (1 * 45)/5
= 45/5
= 9 kg
Mass of coffee A beans = 9 kg
Mass of coffee B beans = ratio of coffee B / total ratio × total mass of the bag
= 5/15 × 45
= 1/3 × 45
= 45/3
= 15 kg
Mass of coffee C beans = ratio of coffee C / total ratio × total mass of the bag
= 7/15 × 45
= (7*45)/15
= 315/15
= 21 kg

¿cuanto suman los angulos interiores de un hexagono? Escribe solo el numero que corresponda a la cantidad, sin el simbolo de grados
Answer:
La suma de los ángulos interiores de un hexágono regular es 720°
Step-by-step explanation:
Asumamos que el hexágono presentado en el enunciado sea regular, el cual es formado por seis triángulos equiláteros, Un ángulo interno del hexágono está formado dos ángulos laterales y vecinos de dos triángulos equiláteros, es decir, dos veces 60°, o sea, 120°. Si el hexágono regular tiene seis ángulos internos de igual medida, entonces la suma de los ángulos interiores es 720°.

The students can be chosen in 116280 different ways to be elected as president, vice president, treasurer and secretary.
What is permutation?"It is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters."
Formula of permutation:The number of ways of obtaining an ordered set of 'r' elements from a set of 'n' elements.
[tex]^{n}P_r=\frac{n!}{(n-r)!}[/tex]
For given example,
there are 20 students in a homeroom
⇒ n = 20
Students can be elected president, vice president, treasurer and secretary.
⇒ r = 4
So, using the formula of permutation, the number of different ways they can be chosen to be elected president, vice president, treasurer and secretary would be,
[tex]\Rightarrow ^{n}P_r=\frac{n!}{(n-r)!} \\\\\Rightarrow ^{20}P_4=\frac{20!}{(20-4)!} \\\\\Rightarrow ^{20}P_4=\bold{116280}[/tex]
Therefore, these 20 students can be chosen in 116280 different ways to be elected as president, vice president, treasurer and secretary.
