Answer:

7:5 is the same as 21: 15

Step-by-step explanation:

21/7 = 3 and 3*5=15

i divided 21 by 7 to see how many times it was multiplied to get there, so i could do the same thing to the 5

I hope this helps :)

Answer:the answer is 15

I got it right lol

Answer:

x = -4

Step-by-step explanation:

-79 = 7x+12x-3

-79 = 19x-3

-19x = 76

x = -4

Answer:

x = -4

Step-by-step explanation:

7x + 3(4x) + 3(-1) = -79

7x + 12x - 3 = -79

19x - 3 = -79

19x = -76

x = -4

Answer:

58.29 cm²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (a + b) , substitute given values into formula

A = [tex]\frac{1}{2}[/tex] × 6.7 × (7 + 10.4)

   = 3.35 × 17.4

   = 58.29 cm²

Answer:

B. Positive slope

Step-by-step explanation:

The line on the graph is positive, as it grows from left to right.

Answer:

Positive Slope

Step-by-step explanation:

The line goes up, which means that it's positive. To be exact the line equation is y = 3x + 1. The slope (3) is positive, which proves that its a positive slope, not negative.

Answer:

5.87

Step-by-step explanation:

I figured it out. Do 10 x sin (36) to get the answer. I would explain, but it's kinda of hard to in this case.

Answer:

Call the line (d): y = ax + b

(d) intersects the vertical axis at the point where the intersection is 3 ⇒x = 0, y = 3 Instead of (d) we have: b = 3

(d) intersects the horizontal axis at the point where the coordinate is -1 ⇒x = −1, y = 0 Instead of (d) we have: −a + b = 0

Replace into b = 3 into -a + b = 0 we have: −a + 3 = 0⇔a = 3

So the equation for the line is y = 3x + 3

The set of numbers 3, 4, and 5 describe the side length of a right triangle.

Option C is the correct answer.

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

Set of numbers:

1, 2, 3

2, 3, 4

3, 4, 5

4, 5, 6

We need to find the set of numbers that describe the side length of a right triangle.

We will apply the Pythagorean theorem to all the sets of numbers.

Using 1,2,3.

1² = 2² + 3²

1 = 4 + 9

1 = 13

2² = 1² + 3²

4 = 1 + 9

4 = 10

3² = 1² + 2²

9 = 1 + 4

9 = 5

This is not true.

Similarly,

Set of numbers: 2,3,4 and 4,5,6 are not true.

Using 3, 4, 5

5² = 3² + 4²

25 = 9 + 16

25 = 25

This is true.

Thus,

The set of numbers 3, 4, and 5 describe the side length of a right triangle.

Option C is the correct answer.

Answer:

the single decimal multiplier is 1.0058

Step-by-step explanation:

Let us have 100

Decreasing by 6% will be

100 - 0.06(100)

= 94

Increasing by 7%

= 94 + 0.07(94)

= 100.58

So

to get the single decimal multiplier,

we have 100.58/100 = 1.0058

Answer:

-95/87

Step-by-step explanation:

Formula to find slope: (y2-y1) / (x2-x1)

In this problem y2 is -3 and y1 is 92. x2 is 97 and x1 is 10.

We substitute these numbers into the equation.

(-3-92) / (97-10)

Then we simplify this by subtracting.

-95/87 is our final answer.

Answer:

Yes

Step-by-step explanation:

In mathematics, a function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set. Typical examples are functions from integers to integers, or from the real numbers to real numbers.

Answer:

Yes, it is a function.

Step-by-step explanation:

use verticle line test

because every y-value only goes to one x-value it passes a verticle line test and is a function

Answer:1$ cards = 11 cards 3$ cards= 13

Step-by-step explanation:the first equation is -x-y=-24 and the second is x+3y=50. Solving them as a system will get 2y=26 to y=13 then plug in 13 to the y for -x-y=-24 to get 11. Mr jacobs is hard I know lol. Use elimination by subtraction and keep the first equation as x+y=24 and then flip to negative

Answer:

$25

Step-by-step explanation:

Given that:

Cost of Ashley's dinner in Bloomington = $20

Sales tax = 10%

Tip = 15% on $20

To find:

Total cost of the meal ?

Solution:

Let us find the sales tax first of all.

Sales tax is 10% of the total bill.

Therefore, sales tax = 10% of $20

[tex]\Rightarrow \dfrac{10}{100}\times 20\\\Rightarrow \$2[/tex]

Tip left is 15% of the total bill.

Therefore, tip = 15% of $20

[tex]\Rightarrow \dfrac{15}{100}\times 20\\\Rightarrow \$3[/tex]

Now, total cost of the meal = Food cost + Sales tax + tip

Total cost of the meal = $20 + $2 + $3 = $25
