A freezer was set at 0 C, sophia reset it to 8.5 C. Would the temperature in the freezer likey rise or drop? By how many degrees?
Answer:
Step-by-step explanation:
1) the temperature rise, because 8.5 is C higher than 0 C
2) 8.5 - 0 = 8.5
So it rised by 8.5 degrees ( to know how many dgrees is is rised subtract the second number from the first number)
Find the total surface area of this cylinder.
Give your answer to 1 decimal place.
24 cm
18 cm
(it's not 2262 or 2021.9 I've already tried those)
Answer:
Step-by-step explanation:
1. Find the circumference of the cylinder: C = 2πr
2. Multiply this result by the height of the cylinder: A = 2πr·h
3. To this result add the surface areas (there are two) of the ends of the cylinder: 2πrh + 2πr²
This is the correct general formula for the surface area of a cylinder of radius r and height h. If you want specific numbers, please share the values of r and h.

Step-by-step explanation:
Count the total numbers of tallies. How many tallies you got put over the total number of A&B
Example: A- III B- IIII Total number of the whole chart- IIIII IIIII IIIII
7/15 and then %/100 which would be a number equal to 7/15.

y=x^2+x-6 what is the x intercepts and how do you get the x intercepts
Answer:
x = - 3, x = 2
Step-by-step explanation:
To find the x- intercepts let y = 0 , that is
x² + x - 6 = 0 ← in standard form
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (+ 1)
The factors are + 3 and - 2 , since
3 × - 2 = 6 and 3 - 2 = + 1 , then
x+ 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 2 = 0 ⇒ x = 2
Elena’s backyard is in the shape of a rectangle. She created a triangular-shaped flower bed (shown as the shaded region) to plant flowers in. The area of the triangular flower bed is square feet. The area of her backyard that does not include the flower bed is square feet.
Answer:
Area of background without flower bed = 575 feet²
Step-by-step explanation:
Given:
Length of rectangle ground = 35 feet
Width of rectangle ground = 20 feet
Height of triangle bed = 10 feet
Base of triangle bed = 25 feet
Find:
Area of background without flower bed
Computation;
Area of background without flower bed = Area of rectangle - Area of triangle
Area of background without flower bed = [l x b] - (1/2)(b)(h)
Area of background without flower bed = [35 x 20] - (1/2)(25)(10)
Area of background without flower bed = 700 - 125
Area of background without flower bed = 575 feet²
Answer:
125 for the backyard with the flower bed, and the backyard that does not include the flower bed is 575 square feet :)

What is the measure of XZ?
A. 36°
B. 144°
C. 72°
D. 18°
Answer:
C.72
Step-by-step explanation:
angle XYZ is an inscribed angle and arc XZ is the arc it intercepts
If you didn't know the measure of an inscribed angle is equal to half the measure of its arc it intercepts or an intercepted arc equals twice the measure of its inscribed angle
Hence, angle XYZ * 2= arc XZ
If Angle XYZ = 36
then 36 * 2 = arc XZ
36 * 2 = 72
hence the answer is C
The measure of arc is 72 degree, the correct option is C.
What is an arc?An arc is formed by two radii and their intercepted part on the circumference.
According to the theorem of arc and subtended angles, the central angle subtended by the arc is double the angle subtended by it on the circumference.
The angle subtended by arc XZ on the circumference is 36 degree.
The angle subtended by the arc at the center is = 2 * 36 = 72 degree.
The arc subtended by the arc at the center of the circle is the measure of the arc.

a bag contains 4 red marbles and 3 blue marbles. Another bag contains 7 green marbles and 6 yellow marbles. You randomly pick one marble from each bag. One marble is blue and second marble is yellow.
Answer: 18/91 or ≈ 0.2
Step-by-step explanation:
Bag one: 4 red + 3 blue = 7 total
Bag two: 7 green + 6 yellow = 13 total
probability of picking blue from first bag: 3/7
probability of picking yellow from second bag: 6/13
3/7*6/13 = 18/91 or about 0.2 chance

which value from the set makes 8y=4 true?
Answer:
B. 1/2
Step-by-step explanation:
because 8y=4
solve for y which is,
8/8y = 4/8 ( devide by 8 to remove 8 from y to let y alone, so what you to on the right hand side you do on the left and vice versa, so devide 4/8 as well.)
y = 4/8
y = 1 /2 ( simplify )
