Which of the following combinations of coins have a value of 140% of a dollar?

140 pennies
14 dimes
10 dimes and 4 nickels
5 quarters and 3 nickels

Answer:

x = 98

y = 126

Step-by-step explanation:

If you match triangle abc to triangle cde, you will match where x and y is.

168 ÷ 12 = 14

Now you multiply 14 by the other side lengths

9 • 14 = 126

7 • 14 = 98

It is similar to a dilation.

Answer: 2 miles per hour

Step-by-step explanation: This is a fraction equal to

6 miles ÷ 3 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 3

6 miles ÷ 3

3 hours ÷ 3

=  

2 miles

1 hour

=  

2 miles

hour

= 2 miles per hour

Answer:

x = -4/17

Step-by-step explanation:

Let's solve your inequality step-by-step.

9−4(x+4)≤7+4(5x+7)

Step 1: Simplify both sides of the inequality.

−4x−7≤20x+35

Step 2: Subtract 20x from both sides.

−4x−7−20x≤20x+35−20x

−24x−7≤35

Step 3: Add 7 to both sides.

−24x−7+7≤35+7

−24x≤42

Answer:

4 students is 20% of 20 students.

Step-by-step explanation:

We can say that 20 students represent 100% and that 4 students represent x% of all students. Then we can use the proportion: 20 : 4 = 100 : x, or 20 / 4 = 100 / x. Then we will cross multiply: 20 x = 4 * 100, 20 x = 400, x = 400 : 20 , x = 20 %. Also we can say that 4 = 1/5 * 20 and 1/5 * 100 = 20 %

4 students are 20 percent of 20 students.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

We can say that 20 students represent 100% and that 4 students represent x% of all students.

Thus, we can use the proportion:

20 : 4 = 100: x, or 20 / 4 = 100 / x.

cross multiply

20 x = 4 * 100

20 x = 400

x = 400: 20

x = 20 %.

therefore, we can say that 4 students are 20 percent of 20 students.

Note: Consider we need to find the vertices of the triangle A'B'C'

Given:

Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.

Triangle A,B,C with vertices at A(-3, 6), B(2, 9), and C(1, 1).

To find:

The vertices of the triangle A'B'C'.

Solution:

If triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C', then

[tex](x,y)\to (y,-x)[/tex]

Using this rule, we get

[tex]A(-3,6)\to A'(6,3)[/tex]

[tex]B(2,9)\to B'(9,-2)[/tex]

[tex]C(1,1)\to C'(1,-1)[/tex]

Therefore, the vertices of A'B'C' are A'(6,3), B'(9,-2) and C'(1,-1).

Answer: 0.9974

Step-by-step explanation:

Let X be the random variable that follows the normal distribution \.

If mean ([tex]\mu[/tex]) = 10 and standard deviation ([tex]\sigma[/tex]) =1

then, the probability of selecting a number between 7 and 13 = [tex]P(7<X<13)[/tex]

[tex]=P(\dfrac{7-10}{1}<\dfrac{X-\mu}{\sigma}<\dfrac{13-10}{1})[/tex]

[tex]=P(-3<z<3)[/tex]                     [Since [tex]z=\dfrac{X-\mu}{\sigma}[/tex]]

[tex]=P(z<3)-P(z<-3) \ \ \ [P(z_1<Z<z_2)=P(Z<z_2)-P(Z<z_1)]\\\\= P(z<3)-(1-P(z<3))\ \ \ [P(Z<-z)=1-P(Z<z)]\\\\=2P(z<3)-1\\\\=2(0.9987)-1\ \ [\text{By p-value table}]\\\\= 0.9974[/tex]

Hence, the probability of selecting a number between 7 and 13 is 0.9974.

Answer:

30,031 is not a prime, is a composite number. Integer prime factorization, as a product of prime factors: 30,031 = 59 x 509.

Step-by-step explanation:

Let's learn by having an example, take number 220 and build its prime factorization.

0) We need the list of the first prime numbers, ordered from 2 up to, let's say, 100: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. Prime numbers are the building blocks of the composite numbers' prime factorization process.

1) Start by dividing 220 by the first prime number in our list, 2 (start with the smallest prime number). We could have skipped the division by 2 if our number were an odd number, ie. 221.

220 ÷ 2 = 110; remainder = 0 => 220 is divisible by 2 (2 | 220) => 2 is a prime factor of 220. => 220 = 2 × 110.

2) Divide the result of the previous operation, 110, by 2, again:

110 ÷ 2 = 55; remainder = 0 => 110 is divisible by 2 (2 | 110) => 2 is once again a prime factor of 220 => 220 = 2 × 2 × 55.

3) Divide the result of the previous operation, 55, by 2, again:

55 ÷ 2 = 27 + 1; remainder = 1 => 55 is not divisible by 2.

4) Move on, divide 55 by the next prime number, 3 (notice that the sum of digits of 55 is 5 + 5 = 10 is not divisible by 3, so 55 is not divisible by 3):

55 ÷ 3 = 18 + 1; remainder = 1 => as we already said, 55 is not divisible by 3.

5) Divide 55 by the next prime number, 5:

55 ÷ 5 = 11; remainder = 0 => 55 is divisible by 5 (5 | 55) => 5 is yet another prime factor of 220 => 220 = 2 × 2 × 5 × 11.

6) Notice that the remaining number, 11, is also a prime number, so we've got already all the prime factors of 220.

7) Conclusion, 220 prime factorization: 220 = 2 × 2 × 5 × 11.

This can be written in a condensed form, in the exponent notation: 220 = 22 × 5 × 11.
