Juan is making a cake for his mom's birthday. For every three cups of
flour, there are four teaspoons of sugar. If Juan used 33'cups of flour,
how many teaspoons of sugar did he use? Be sure to identify the
multiplicative rule.
Answer:
44 teaspoons
Step-by-step explanation:
33 divided by 3 is 11 and 4 x 11 is 44 if juan used 4 teaspoons of sugar every 3 cups of flour then 3 goes into 33 11 times and 4 x 11= 44

A seed weighs 0.00002421 ounces. What is this value in correct scientific notation?
A) 2421 x 108
B) 2.421 x 105
2.421 x 10-5
D 2421 x 10
-8
Answer:
C) 2.421 x 10^-5
Step-by-step explanation:
A negative exponent on a power of ten will make the decimal point go back that amount of times to the left, making it a lesser number. A positive exponent will cause it to move to the right, making the number greater. We aren’t going to need to make any of the numbers being multiplied greater, so we can eliminate the first two. Then we need to solve the others. We can do this by moving the decimal the amount of times that we see the exponent equals. Since C is -5, we move it to the left 5 times, and get the weight of the seed; 0.0002421.

A pole that is 2.6 m tall casts a shadow that is 1.26 m long. At the same time, a nearby tower casts a shadow that is 37.25 m long. How tall is the tower?
Answer:
Step-by-step explanation:
The ratio of height to shadow length will be proportional.
2.6 / 1.26 = h / 37.25
h = 37.25(2.6)/1.26 = 76.865079...
h = 76.9 m

complete an activity in which they grabbed as many
bite-sized pretzels as they could with their dominant
hand, without crushing them. The teacher then
measured their handspan in centimeters. A regression
analysis was completed and the value for was
52.1%
* About 52.1 percent of the variation in handspan is
accounted for by the linear relationship formed with
the number of bite-sized pretzels grabbed with the
dominant hand.

Solve for X in the questions
Step-by-step explanation:
x = 360°- (90°+36°+36°)
= 360 - (162°)
= 198°
___________
[tex] \: [/tex]
Step by step :PQR = 360°
QR = 90°
PQ = 36°
RX = 36°
Soo :
x = 360° - (90° + 36° × 2)
x = 360° - (90° + 72°)
x = 360° - (162)
x = 198°✔
Give an example of a number between 20 and 50 which is a multiple of 3 and also a factor of 84.
Answer:
