Answer:

1.3??

Step-by-step explanation:

Answer:

130%

Step-by-step explanation:

Let x be the unknown number.

of the unknown number = [tex]\frac{13}{10}[/tex] [tex]x^{}[/tex]= 1.3x

We need to find the [tex]\frac{13}{10}[/tex] of a number is what percent of that number.

%=[tex]\frac{new value}{Inital Value}[/tex] x 100

Substitute 1.3x for new value and x for initial value in the above formula.

%=[tex]\frac{1.3x}{x}[/tex]x 100

Cancel out the common factors.

%= 1.3 x 100

%= 130

Therefore, [tex]\frac{13}{10}[/tex] of a number is 130% of that number.

The value of her investment at the end of 7 years is $11804

The given parameters are

Principal, P = $5000

Rate, r = 4.5%

Time, t = 7 years

The value is then calculated as:

Value = P * P(1 + r)^t

So, we have:

Value = 5000 + 5000 * (1 + 4.5%)^7

Evaluate the expression

Value = 11804

Hence, the value of her investment at the end of 7 years is $11804

If th3 coordinate point is dilated by a factor of 2, then the resulting coordinate will be at (-14, 10)

Given the coordinate point (x, y), if this coordinate is dilated by a factor "k", the resulting coordinate will be at (kx, ky)

Note that each of the coordinates was multiplied by a scale factor

For the given coordinate (-7, 5), if this coordinate point is dilated by a factor of 2, then the resulting coordinate will be at (-14, 10)

Answer: x=50

Step-by-step explanation:

Use the distributive property to multiply -0.2 by x-20.

-0.2x+4=44-x

Add x to both sides.

-0.2x+4+x=44

Combine -0.2x and x to get 0.8x.

0.8x+4=44

Subtract 4 from both sides.

0.8x=44-4

Subtract 4 from 44 to get 40.

0.8x=40

Divide both sides by 0.8.

x=40/0.8

Expand 40/0.8 approx 50 by multiplying both numerator and the denominator by 10.

X=400/8

Divide 400 by 8 to get 50.

x=50

Answer:

2 1/2 cups of flour

Step-by-step explanation:

Priya is making 3 loaves of bread, so she will use 7 1/2 cups of flour.

Andre is making 1 loaf of bread, which is 1/3 the amount of loaves Priya is making. So, he will be using 1/3 the amount of flour Priya is using. So all we have to do is take 7 1/2 and divide it by 3:

7.5/3 = 2.5

Andre will use 2 1/2 cups of flour.

Answer:

17²=15²+x²

289=225+x²

288-225=x²

64=x²

x=6

Answer:

8

Step-by-step explanation:

By Pythagoras theorem,

(hypotenuse)² =  (altitude)² + (base)²

(17)² = x² + (15)²

(17)² - (15)² = x²

289 - 225 = x²

x² = 64

x = √64

x = 8

Answer:

88.4

Step-by-step explanation:

33.5 + 45.9 = 88.4

The length of the city train is 79.4 feet.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Length of the Bus = 33.5 feet.

Length of the City train:

= Length of the Bus + 45.9

= 33.5 + 45.9

= 79.4 feet.

Thus,

The city train is 79.4 feet.

Answer:

  7 square feet per student

Step-by-step explanation:

To find "A per B", divide the quantity of A by the quantity of B. It can help to keep the units with the numbers.

Here, you want area per student, so divide area by students:

  area per student = (357 ft²)/(51 students) = 7 ft²/student

The relationship is 7 square feet per student.

Answer:

(3, 10 ) and (7, 30 )

Step-by-step explanation:

Given the 2 equations

5x - y = 5 → (1)

2y - x² = 11 → (2)

Rearrange (1) expressing y in terms of x

y = 5x - 5 → (3)

Substitute y = 5x - 5 into (2)

2(5x - 5) - x² = 11

10x - 10 - x² = 11 ← rearrange into standard form

x² - 10x + 21 = 0 ← in standard form

(x - 3)(x - 7) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 7 = 0 ⇒ x = 7

Substitute these values into (3) for corresponding values of y

x = 3 → y = 5(3) - 5 = 15 - 5 = 10 ⇒ (3, 10 )

x = 7 → y = 5(7) - 5 = 35 - 5 = 30 ⇒ (7, 30 )

The functions for the different interval is

g(x)= [tex]\rm \sqrt[3]{x+5}[/tex] , x ≤ -4

     = -x² +11 , x > -4

The value of g(-4) will be determined by using g(x)= [tex]\rm \sqrt[3]{x+5}[/tex]

Substituting the value x = -4

g(x) = [tex]\rm \sqrt[3]{-4+5}[/tex]

Answer:

87

Step-by-step explanation:

Answer:

81.859%

Step-by-step explanation:

We solve the question using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean = 80 mph

σ is the population standard deviation = 7 mph

For x = 66 mph

z = 66 - 80/7

z = -2

Probability value from Z-Table:

P(x = 66) = 0.02275

For x = 87 mph

z = 87 - 80/7

z = 1

Probabilith value from Z-Table:

P(x = 87) = 0.84134

The probability of the trials will give the DeLorean a speed between 66 mph and 87 mph is calculated as:

P(x = 87 mph) - P(x = 66 mph)

0.84134 - 0.02275

= 0.81859
