60% of the 50 students in Jessie’s gym class are 12 years old. How many students in Jessie’s class are 12 years old?

A tape diagram. There are 60 students out of 100 that are 12 years old. There are question mark students out of 50 that are 12 years old.

What steps should you use to find 60% of 50? Check all that apply.
100 ÷ 20 = 50
100 ÷ 2 = 50
60 ÷ 2 = the number of students who are 12 years old.
60 ÷ 20 = 3 students
60 ÷ 2 = 30 students
30 of the 50 students are 12 years old.

Answer:

10.5

Step-by-step explanation:

because 10.5x2=21. and 45+13+21=79, 100-79= 21.

Step-by-step explanation: Since the line crosses the y-axis at 6, the y-intercept is 6.

Answer:

The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation.

Answer:

It's simple.

So, 30 is half of 15. And 3x5=15 So, I think the best estimate would be 15+15=30 pieces.

Meaning the two pieces are both of the fiveteens.

Answer:

83

Step-by-step explanation:

The measure of the side v for the triangle is 82.8 inches.

One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.

Given that in ΔUVW, w = 79 inches, u = 57 inches and ∠V=73°. The measure of the side v is calculated by the formula,

v² = u² + w² - 2uvcosv

v² = ( 57)² + (79)² - 2 x 57 x 79 x cos73

v² = 6856.9

v =√6856.9

v = 82.8 inches

Hence, the value of v will be 82.8 inches.

b) -4

Step-by-step explanation:

Well your at 2 and going to -2 so on a number line you be going back or left.

Going two left gets you to zero and going two more get you -2. So in total you went back four and that be represented as -4.

Answer:

$20.40

Step-by-step explanation:

20% off means that the new price of the skirt will be 80% of the original price:

$30(100%  – 20%) = $30(80%)

Converting the percent to a decimal gives:

$30(0.8) = $24.00

There is an additional 15% off the sale price of $24.00, so the final price is 85% of the sale price:

$24(100%  – 15%) = $24(85%)

Again converting the percent to a decimal gives:

$24(0.85) = $20.40

ΔABC ≅ ΔQPR

Step-by-step explanation:

if you were to reflect it, they would line up also A ≅ Q because their angles are the same and I know that because of the markings, they both have one arc and B and P both have two arcs meaning they are congruent and C and R both have three arcs so they are congruent.

Step-by-step explanation:

Answer: g(x) = 3*Ix + 2I - 5

Step-by-step explanation:

First, let's define the transformations in a general way.

A vertical stretch of a scale factor A, is written as:

g(x) = A*f(x)

A vertical shift of A units is written as:

g(x) = f(x) + A

if A is positive, the shift is up, if A is negative, the shift is down.

A horizontal shift of A units is written as:

g(x) = f(x - A)

If A is positive, the shift is to the right.

If A is negative, the shift is to the left.

Then we start with the absoulte value parent function f(x) = IxI

"The graph of the absolute value parent function is vertically stretched by a factor of three"

We start with:

g(x) = 3*f(x)

"then shifted two units left"

g(x) = 3*f(x - (-2))

"and five units down."

g(x) = 3*f(x + 2) - 5.

and knowing that f(x) = IxI, we have:

g(x) = 3*Ix + 2I - 5

Answer: 500 messages will the costs for the two plans be the same.

Step-by-step explanation:

Let x= Number of text messages .

Given: One plan has a monthly fee of $15 with a charge of $0.05 per text.

i.e. Total cost of plan = 15+0.05x

The other plan has a monthly fee of $5 with $0.07 per text.

i.e. Total cost of plan = 5+0.07x

As per given ,

[tex]5+0.07x=15+0.05x\\\\\Rightarrow\ 0.07x-0.05x=15-5\\\\\Rightarrow\ 0.02x=10\\\\\Rightarrow\ x=\dfrac{10}{0.02}\\\\\Rightarrow\ x= \dfrac{1000}{2}\\\\\Rightarrow\ x=500[/tex]

Hence, 500 messages will the costs for the two plans be the same.
