Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Answer:
Area of rectangle : 16 square units
Area of triangle : 6 square units
Area of figure : 22 square units
Step-by-step explanation:
The area of a rectangle = length x width
Here, the length of the rectangle is 4 units as well as the width
This means the area of the rectangle is 4 x 4 = 16 units²
The area of a triangle = ( length of base x height ) / 2
Here, the length of the base is 4 units and the height is 3 units
So the area of the triangle = (4x3)/2 = 12/2 = 6 units²
The area of the figure = sum of the two areas
So the area of the figure is 6 + 16 = 22 units²
Answer:
16 + 6 = 22 units²
Step-by-step explanation:
A square is a special kind of closed figure with four straight sides and four right angles that also has sides that all have equal length. Therefore, we can conclude that: A Square is a special kind of rectangle. Every Square is a rectangle, but not every rectangle is a square
Square Area = W x L or l²
Square Area = 4 x 4 = 16 units²
Triangle Area = 1/2 b x h
Triangle Area = 1/2 4 x 3
Triangle Area = 6 units²
Total Area = just sum
16 + 6 = 22 units²
Bud’s cheeseburger and fries contained 1310 milligrams and 350 milligrams of sodium, respectively. Together they contained 66.4% of the recommended daily intake of sodium for a 2,000 calorie diet. What is the daily recommended intake of sodium for a 2,000 calorie diet? Show your work.
Answers
The daily recommended intake of sodium for a 2,000 calorie diet is 2000 calorie diet is 2500 mg.
What is diet?Healthy diet:
A healthy diet helps protect against malnutrition in all its forms and is a foundation for health and development. It also helps to prevent noncommunicable diseases including diabetes, cardiovascular diseases, some cancers and other conditions linked to obesity.
In order to calculate the daily intake of sodium we first need to calculate the mass of sodium present in both snacks, this is given by their sum.
\(\text{Total sodium = 1310 + 350 = 1660}\)
We can now apply a rule of three for which the total sodium from the snacks is related to 66.4% in the same proportion as "x" mg, which is the value we want to know, is related to 100%. So we have:
\(\frac{1660}{x} \frac{mg}{mg} = \frac{66.4}{100} \\\\66.4*x = 1660*100\\x=\frac{166000}{66.4} = \bold{2500\text{ mg}}\)
Hence, the daily recommended intake of sodium for a 2,000 calorie diet is 2000 calorie diet is 2500 mg.

Answer:
(D) 85 cm².
Step-by-step explanation:
To find the area of a triangle, we can use the formula:
Area = (1/2) x base x height
In this case, we are given the lengths of three sides of the triangle, but we need to find the height. One way to do this is to use Heron's formula to calculate the area directly, but another approach is to use the Pythagorean theorem to find the height.
We can see that the side lengths of the triangle are 17 cm, 10 cm, and 9 cm. Let's assume that the side of length 17 cm is the base of the triangle. Then, we can draw an altitude from the vertex opposite the base to the base, creating two right triangles. The height of the triangle is the length of this altitude.
Using the Pythagorean theorem in one of the right triangles, we can solve for the height as follows:
(Height)^2 = (10 cm)^2 - (4.5 cm)^2
Height = sqrt[(10 cm)^2 - (4.5 cm)^2]
Height = sqrt[100 cm^2 - 20.25 cm^2]
Height = sqrt(79.75) cm
Height ≈ 8.93 cm
Now that we have the base and height of the triangle, we can use the formula for the area of a triangle:
Area = (1/2) x base x height
Area = (1/2) x 17 cm x 8.93 cm
Area ≈ 76.025 cm²
Therefore, the area of the triangle is approximately 76.025 cm². None of the answer choices match this result exactly, but the closest option is (D) 85 cm².
Answer:
A
Step-by-step explanation:
The formula of a triangle is Base x Height ÷ 2 = Area
10 x 9 = 90 sq cm
90 ÷ 2 = 45

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answers
Answer:
1 1/5.
Step-by-step explanation:
To divide a fraction by another fraction you have to change the equation like "Keep, Switch, Flip".
For the problem 24/25 ÷ 4/5,
You KEEP the first fraction as is, so 24/25
Then, you SWITCH the sign from division to multiplication.
Finally, you FLIP the second fraction upside down, (the reciprocal). So it's 5/4.
The equation is now 24/25 * 5/4, which we can just multiply the numerators and denominators. (or cross cancel first)
24 * 5 = 120
25 * 4 = 100
the fraction is 120/100. Simplified, it can be divided by 10 to make 12/10, and finally divided by 2 to make 6/5, or 1 1/5.

Given
Total Capacity of a cup = 7/9 pints
Coffee to be added in a cup = 2/3 pints

WILL CHOOSE BRAINLIEST! The height of a baseball, h (in feet), as a function of time, t (in seconds), is given by the equation h(t)=-16t²+32t+3. find the average velocity (in ft/sec) of the baseball from t=0 to t=1.
Answers
Answer:
Given the equation y = -16t^2 + 96t + 3, we know a = -16, b = 96, c = 3.
Let's solve for h in this problem.
h = -b/2a
h = -(96) / 2(-16)
h = -96 / -32
h = 3 seconds
Now let's add t=3 to our equation:
y = -16t^2 + 96t + 3
y = -16*(3)^2 + 96*(3)+ 3
y = -144 + 288 + 3
We now know that the vertex is (3,147), which means that the ball's maximum height is 147 feet.
Answer:
Step-by-step explanation:
Find the height at h(0) and h(1)
h(0) = 3 ft
h(1) = -16 + 32 + 3 = 19 ft
It takes 1 second to go from 3 feet to 19 feet
(19-3) ft / 1 sec = 16 ft/sec
