Joey bought a 3-kilogram bag of carrots from the grocery store. He added 0.8 kilograms of carrots to a pot of vegetable soup. Then, he grated 400 grams of carrots for his carrot cake. How many kilograms of carrots does he have left?
The amount of carrots Joey has left according to the task content is; 1.8kg.
How many kilograms of carrots does he have left?It follows from the task content that the quantity of carrots he has initially is; 3 kg.
On this note, upon adding 0.8 kilograms of carrots to a pot of vegetable soup, and grated 400 grams of carrots = 0.4kg, it follows that the quantity of carrot left is;
= 3 - 0.8 - 0.4 = 1.8kg.

Topic: Perpendicular to Chord Property
Since the diagram shows a right triangle and gives out some measurements of the sides, you can use the Pythagorean Theorem ([tex]a^{2}+b^{2}=c^{2}[/tex]) to find the length of MP.
Given:
hypotenuse = 7 – because the radius is 7 units and it can be used as the hypotenuse
One side of the triangle = 4 – because the length of PO is 4 units and it can be used as one sides of the triangle
To Solve:
Since we know two values of the triangle, you can use the Pythagorean Theorem ([tex]a^{2}+b^{2}=c^{2}[/tex]) to find what the other value is. The variables c and b in the formula are already given, and we need to find what a is to find the length of MP. So, plug the given values of c and b into the formula:
[tex]a^{2}+4^{2}=7^{2}[/tex]
Simplify:
[tex]a^{2}+16=49[/tex]
Subtract 16 from both sides of equation:
[tex]a^{2}=33[/tex]
Do the square root of both sides to isolate the variable a:
[tex]\sqrt{a^{2}}=\sqrt{33}[/tex]
Evaluate:
[tex]a=\sqrt{33}[/tex] Which simplifies to [tex]a= 5.744562646....[/tex] and round it to the nearest tenth to finally get [tex]a=5.7[/tex]
Answer: The length of MP is 5.7 units
How to solve Part AIf you look at the diagram in the question, you can see that the length of MN is twice the length of MP. So multiply the length of MP, which is 5.7, by 2:
5.7 · 2 = 11.4
Answer: The length of MN is 11.4 units

Question 2:How to solve Part ALook at the first image below ↓
Description of the first image:
The first image shows a drawn image of the circle with labeled parts and measurements from the infomation given from the question.
The diameter is 26cm, which means that the radius is 13cm because the radius half of the diameter in a circle. The very top line is the surface of the water where it’s filled and it has a length of 20cm. Side b of the triangle is 10cm becuase it’s half the length of the the surface of the water bowl. The hypotenuse (side c) is 13cm because it’s the length of the radius. And side a is what what we need to find because it’s the distance between the surface of the water and the center of the bowl. But after when you find the length of side a, you need to add the length of the radius (which is 13cm) to the length of side a because that’s the rest of the length/depth of the water that’s filled in the bowl. The length of the radius is included with the depth of the water.
Total information given:
⇒ radius = 13cm – because the radius is half of the diameter, and the diameter has a length of 26cm
⇒ length of the surface where the water’s filled = 20cm
⇒ hypotenuse (side c) = 13cm – because it’s the length of the radius
⇒ side b = 10cm – because it’s half the length of the surface where the water’s filled
To Solve
Since there is a right triangle shown in the image, you can use the Pythagorean Theorem ([tex]a^{2}+b^{2}=c^{2}[/tex]) to find the missing length of side a. Plug the given values of c and b into the formula:
[tex]a^{2}+10^{2}=13^{2}[/tex]
Simplify:
[tex]a^{2}+100=169[/tex]
Subtract 100 from both sides of the equation:
[tex]a^{2}=69[/tex]
Do the square root of both sides to isolate the variable a:
[tex]\sqrt{a^{2}}=\sqrt{69}[/tex]
Evaluate:
[tex]a=\sqrt{69}[/tex] Which simplifies to [tex]a= 8.30662386....[/tex] and round it to the nearest tenth to finally get [tex]a[/tex] ≈ [tex]8.3[/tex]
This means that 8.3 is just the length of side a, which is the length between the surface of where the water’s filled and the center of the circle. But, now you need to add 13 to 8.3 to find the total depth of the water because the length of the radius is included with the depth of the water.
So,
13 + 8.3 = 21.3
Answer: The depth of the water is approximately 21.3 cm

A rectangle has a diagonal of 15ft. The width of the triangle is 12ft. What is the area of the rectangle.
9514 1404 393
Answer:
108 ft²
Step-by-step explanation:
The length of the other side of the rectangle can be found using the Pythagorean theorem.
15² = 12² + x²
x = √(225 -144) = √81 = 9
So, the rectangle is 9 ft by 12 ft. Its area is the product of those dimensions:
A = bh
A = (12 ft)(9 ft)
A = 108 ft² . . . . area of the rectangle

The data manager for a state political party gathered data to determine how many citizens would support the party's senate candidate. He polled citizens in 30 similarly sized senate districts and found a sample mean of 70,438 citizens. Statewide data shows that the population standard deviation is 645.3. What is the approximate 90% confidence interval for this situation?
Answer:
The approximate 90% confidence interval is;
70,244 to 70,732
Step-by-step explanation:
Here, we want to calculate the approximate 90% C.I for the situation
Mathematically;
CI = mean ± (z * SD)/√n
From the question;
mean = 70,438
SD = 645.3
n = 30
we can get z from the CI table
90% CI is same as; 1.645 z-score
So , substituting these values;
CI = 70,438 ± ( 1.645 * 645.3)/√30
CI = 70,438 ± 194
So the CI = 70,438 -194 to 70,438 + 194
= 70,244 to 70,732
Answer:
B. 70,244 and 70,632

Suppose you have a rectangle with length 8 cm and width 3 cm. Now suppose the sides are doubled. Find the percent of
increase in the perimeter.
Answer:
200%.
Step-by-step explanation:
Original perimeter = 2(8 + 3) = 22 cm
After doubling each side, perimeter = 2(16+6) = 44 - that is twice the original.
Answer is 200%.

If a numberis divisible by two co-prime numbers then it is also divisibe by their product
It's true that co-prime number is divisible by their product.
Co-prime numbers are pairs of numbers that do not have any common factor other than 1.
e.g., ( 4,7), (2,3), (5,7,9) etc.
Let's take two co-prime numbers i.e., x and y i.e., (x, y)
The product of them is ( x × y)
Therefore,
x × y/ x = y ,and x × y/ y = x
Lets understand with an example,
Let's take two co-prime be (2,5), its product be 2×5 = 10
so when we divide product with the number i.e., 10/2=5 and 10/5=2 which is divisible.
Therefore the co-prime number is divisible by their product.

Helen used 14 of her savings for her first year of college. 38 of that money was spent on her housing and meals. Which equation shows the fraction of her total savings that was spent on her housing and meals?
Answer: 3/32
Step-by-step explanation:
Here's the complete question:
Helen used 1/4 of her savings for her first year of college. 3/8 of that money was spent on her housing and meals. Which equation shows the fraction of her total savings that was spent on her housing and meals?
Since we are told that Helen used 1/4 of her savings for her first year of college and that 3/8 of that money was spent on her housing and meals.
To calculate the fraction of her total savings that was spent on her housing and meals, we would multiply 1/4 by 3/8. This will be:
= 1/4 × 3/8
= 3/32
