Ace accuracy = 7/10 = 70%

What is the volume of the composite figure shown? Use 3.14 for π.
Answer:
25.12
Step-by-step explanation:
the formula of a cone is pi r^2 * h/3
r = radius and h = height
the radius is 2 and the height is 3
and the question says use 3.14 instead of pi so
we have
3.14 * 2^2 * 6/3
2*2 or 2^2 = 4
3.14 * 4 * 6/3
6/3 = 2
3.14 * 4 * 2
4*2 = 8
and 8 * 3.14 is 25.12

4,570 =4 thousands + 5 hundreds + 7 tens
4,570 =3 thousands + ★ hundreds + 7 tens
★ = _______ whoever will give me a correct answer and explanation to the answer will be marked as brainliest
Answer:
15 hundreds = star
Step-by-step explanation:
Move 1 thousand into hundreds place with the 5 hundreds that were already there. 5 plus 10 =15. We just don't usually think of it like that because of place value.
Answer:
I guess the answer is or the ★=2
Step-by-step explanation:
because if u add like now add 2+5=7,which is 7 tens in both side or 3 the one of thousand like 3+2 u get 5 the one of hundreds so that is how i get 2

the width w of a rectangular swimming pool is x+5 the area a of the pool is x^2+4-5
what is an expression for the length of the pool? step by step
Answer:
x-1
Step-by-step explanation:
Area= x^2+4x-5
Width= x+5
Area= Length*breadth
x^2+4x-5=length*x+5
Length=x^2+4x-5/x+5
Therefore, length= x-1

Jimmy's truck consumed 2 gallons of gasoline while travelling a distance of 76 km. He has 1.5 gallons left in the tank. How much farther can his truck go?
_______ km
I GIVE BRAINLIEST TO THE FIRST CORRECT ANSWER!!
Answer:
[tex]57\:\mathrm{km}[/tex]
Step-by-step explanation:
Since the question implies his truck travels at a constant distance per gallon, we can set up the following proportion to find how much father his truck can go.
Let [tex]x[/tex] represent how much farther his truck can go, in kilometers:
[tex]\frac{2}{76}=\frac{1.5}{x}[/tex]
Cross-multiplying, we get:
[tex]2x=76\cdot 1.5,\\x=\frac{76\cdot 1.5}{2}=\boxed{57\:\mathrm{km}}[/tex]
Answer:
Step-by-step explanation:
2 ÷ 76 = 1.5 ÷ d
2d = 76 × 1.5
d = 57 km
2/3 times 3/2 = 6/6 =

Which sentence correctly compares the two points shown on the number line? -1 > 0.25 , -1 < -0.25, -0.25 < -1
Answer:
-1<-0.25
With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong
Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.
