Answer:
52 cm²
Step-by-step explanation:
First, we find the area of the bottom rectangle. We see it's 4 high and 10 wide, so 4x10 is 40. Then, we see that the small figure in the top right has a height of 4 and width of 3, so 4x3 = 12, add those and you get 52.
A textbook store sold a combined total of 411 psychology and history textbooks in a week. The number of history textbooks sold was 69 less than the number of
psychology textbooks sold. How many textbooks of each type were sold?
Answer:
Step-by-step explanation:
h and p are the number of history and psych textbooks, respectively.
store sold a total of 411 textbooks in a week.
h + p = 411
The number of history textbooks sold was 69 less than the number of psychology textbooks sold.
h = p - 69
Substitution
(p-69) + p = 411
2p = 411+69
p = 240
h = p-69 = 171
171 history books and 250 psych books
Solve by using substitution.
=3−8
=−4
Answer:
I'm going to assume that you meant y=3x-8 and y=-4
This means that you would substitute -4 into the spot of y which gives you -4=3x-8. Once solved you would receive x=4/3.
Hope I helped have a nice day :)

Divide 750 into the ratio 2:3
Answer:
300 : 450
Step-by-step explanation:
sum the parts of the ratio, 2 + 3 = 5 parts
Divide 750 by 5 to find the value of one part of the ratio
750 ÷ 5 = 150 ← value of 1 part of the ratio , then
2 parts = 2 × 150 = 300
3 parts = 3 × 150 = 450
Then 750 in the ratio 2 : 3 = 300 : 450
The required answer is 750 in the ratio 2 : 3 = 300 : 450.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have to divide 750 into the ratio 2:3
The ratio is given in the question
⇒ 2:3
We can see that the sum of the parts of the given ratio as
⇒ 2 + 3 = 5 parts
Divide 750 by 5 to determine the value of one part of the ratio
So the value of 1st part of the ratio
⇒ 750 ÷ 5 = 150
Now, 2nd parts = 2 × 150 = 300
And, 3rd parts = 3 × 150 = 450
So, 750 in the ratio 2 : 3 = 300 : 450
Therefore, the required answer is 750 in the ratio 2 : 3 = 300 : 450.

Which side lengths form a right triangle? Choose all that apply. 5, the square root of 8, 33 or 8,15,17 or the square root of 2, the square root of 2, 2
Answer:
17² = 15² + 8²
2² = (√2)² + (√2)²
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as right angled, acute, obtuse and isosceles triangle.
In right angle triangle, one angle is 90°. From Pythagoras theorem, the square of the longest side (hypotenuse) is equal to the sum of the square of the two sides. Hence:
33² ≠ (√8)² + 5² (not right triangle)
17² = 15² + 8² (right triangle)
2² = (√2)² + (√2)² (right triangle)

Zack’s Italian Pizza Bar baked 2,000 pizzas in the first year that they were open. In the second year, they baked 3,000 pizzas and in the third year 4,000 pizzas. Write a function that could model the growth of pizzas baked, where x = 0 is the first year.
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of years, where x = 0 represent the first year. Let y represent the number of pizzas baked.
In the first year(i.e. at x = 0), 2000 pizza was baked. This can be represented by (0, 2000).
In the second year(i.e. at x = 1), 3000 pizza was baked. This can be represented by (1, 3000).
In the third year(i.e. at x = 2), 4000 pizza was baked. This can be represented by (2, 4000).
Therefore, the relationship between x and y is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
Using the points (0, 2000) and (2, 4000):
[tex]y-2000=\frac{4000-2000}{2-0} (x-0)\\\\y-2000=1000x\\\\y = 1000x+2000[/tex]

Pls, help me with this question
Answer:
37.5
Step-by-step explanation:
∠ABC (x) is an inscribed angle with arc AC being the arc it intercepts
An inscribed angle is equal to half the measure of its intercepted arc.
If arc AC = 75
Then x = [tex]75\frac{1}{2}[/tex]
75 / 2 = 37.5
Hence, x = 37.5
A number X rounded to 2 decimal places is 7.42. Write down the error interval for X
Answer:
X = [7.415,7.419].
Step-by-step explanation:
The number is 7.42 so the thousandth place is from 5 to 9 and hundredth place is 1. i.e. 7.415, 7.416, 7.417, 7.418, 7.419. As 7.415 rounded to 2 decimal place is 7.42. The interval in x[7.415, 7.419].
