Work for 19:
The chart is incorrect because it calculates 40% of 34 instead of 40 percent of x (we got 85% for our answer but I'm using x as the unknown number) results in the number of 34.
Percentage of 40% of what number = 34?
40% of what number = 34 is equivalent to: 40% × ? = 34
--------------------------
40% × ? = 34
? =
34 ÷ 40% =
34 ÷ (40 ÷ 100) =
(100 × 34) ÷ 40 =
3,400 ÷ 40 =
85
Proof:
If 40% × 85 = 34 =>
Divide 34 by 85...
... And see if we get as a result: 40%

Acute triangle
Step-by-step explanation:
All the three angles of the triangle is less than 90, all angles are acute. So, it is acute triangle.
If any one of the three angles is 90, then it is right triangle.
If any one of the three angle is more than 90, then it is obtuse triangle.

Step-by-step explanation:
Fig = rectange 1 +rectange 2
Area of rec 1 = l x b = 3 x 2 = 6 ft2
Area of rec2 = l x b = 11 x 3 = 33ft2
Area of whole fig = area of rec 1+ area of rec 2 = 33+6 = 39 sq.ft
I hope im right!!
Answer:
The answer is 39 square ft
Step-by-step explanation:
first we have to divide it into parts.
I did:
11 by 3
and
3 by 2
so 11x3=33
and 3x2=6
so 33+6=39 square ft
There are two mystery numbers. The sum of 2 times the first number and 5 times the second number is -5. The sum of 3 times the first number and 10 times the second number is -5. What are the two numbers?
Answers
Answer:
the two numbers are -5 and 1
Step-by-step explanation:
Let x and y be the first number and second number respectively.
According to the question, we can find 2 equations:
2x + 5y = -5
3x + 10y = -5
On solving,
x = -5
y = 1
Answer:
X=-5,Y=1
Step-by-step explanation:
First equation: 2X+5Y=-5
Second equation:3X+10Y=-5
If we subtract the first from the second equation
(3X+10Y)-(2X+5Y)= 0 so, X+5Y= 0
So X= -5Y .then substitute in the second equation
So ,3(-5Y)+10Y= -5 , therefore -15Y + 10Y=-5 so, -5Y=-5 which means that Y=1
Then substitute with that in the first equation so 2X+5= -5
2X= -10 therefore X=-5

f(x) = x^2 . What is g(x)?
Answers
Answer:
g(x) = (1/4x)^2
Step-by-step explanation:
Given f(x), we want to get g(x)
As we can see, the point (4,1) lies on the graph of g(x)
So the correct option will be the one where g(4) = 1
Let us take a look at the second option
g(x) = (1/4x)^2
Here,
g(4) = (1/4 * 4)^1 = 1^1 = 1

Find the length of the hypotenuse of a right triangle with legs measuring 7 cm and 9 cm. Round your answer to the nearest tenth.
Answers
Answer:
Hypotenuse = 11.4 cm
Step-by-step explanation:
Hypotenuse ² = opposite ² + adjacent ²
Opposite = 7 cm
Adjacent = 9 cm
Hypotenuse ² = opposite ² + adjacent ²
= 7² + 9²
= 49 + 81
Hypotenuse ² = 130
Hypotenuse = √130
= 11.40
Hypotenuse = 11.4 cm

Find the surface area of the cube show below

Answers
Answer:
Step-by-step explanation:
there are 6 sides on a cube
surface area = 6 times the area of one face of the cube
= 6 times ( a side times another side) note all sides are equal
= 6(side)² is a side equal to 2/3 ?? if it is ....
= 6(2/3)²
= 6(2/3)(2/3) one of the 3s divide into 6 twice
= 2(2)(2/3)
= 2³ / 3
= 2x2x2 / 3
= 8 /3
= 2 and 2/3 units²
Which line is a graph of the equation: 2x + 5y = -10?
A line a

C line c
D line d
Answers
Answer: D. line d
Step-by-step explanation:
Answer: D. line d
A function is general describe as y = mx + b, so we need to set this function in y form.
2x + 5y = -10
5y = - 2x - 10 (Subtract 2x from both side, to make sure there are only y value in the left side)
y = - 2/5x -10/5 (Divide by 5 from both side)
y = -2/5x - 2 (Simplified)
-2/5x was the m or the slope, it shows how the line was change. -2/5x is negegative, which means is decreasing, and going downward, only line b and d fits.
-2 is the y-intercept, where y is equal to 0, (-2,0)
The y-intercept for line b is (2,0), so it can't be. Thus, the y-intercept for line d is (-2,0), so it fit.

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
We can use proportions to solve this problem.
If 2/3 cups of sugar are used to make 1/2 batch of cookies, then we can set up the following ratio:
2/3 cups of sugar : 1/2 batch of cookies
We want to find how much sugar is needed for a full batch of cookies. Let's call this amount x cups of sugar.
We can set up another ratio:
x cups of sugar : 1 full batch of cookies
To solve for x.
(2/3 cups of sugar) x (1 full batch of cookies) = (1/2 batch of cookies) x (x cups of sugar)
2/3 = 1/2 (x)
x = (2/3) / (1/2)
x = 4/3
Therefore,
Lindsey would need to use 4/3 cups of sugar to make a full batch of cookies.
