A railroad car container can hold 42,000 pounds. Mr. Evans wants to ship 90 ovens and some freezers in the same container. If each freezer weighs 600 pounds, how many freezers could be shipped in the container? Explain.
By the triangle sum theorem, the sum of the angles in a triangle is equal to Response area. Therefore, m∠A+m∠B+m∠C=180°. Using the Substitution Property, (4x)°+90°+(x+10)°=180°. To solve for x, first combine like terms to get 5x + 100 = 180. Using the Response area, 5x = 80. Then, using the division property of equality, x = 16. To find the measure of angle A, use the Response area to get m∠A=4(16)°. Finally, simplifying the expression gets m∠A=64°.
Which equation accurately represents this statement? Select three options. Negative 3 less than 4.9 times a number, x, is the same as 12.8. Negative 3 minus 4.9 x = 12.8 4.9 x minus (negative 3) = 12.8 3 + 4.9 x = 12.8 (4.9 minus 3) x = 12.8 12.8 = 4.9 x + 3
a proposed null hypothesis states that there is no difference in the population mean heights of two neighboring districts. the difference of the sample means is 10 cm, and the standard deviation of the difference sample means is 6 cm. which conclusion can we draw at the 68% confidence level?
The function 1 (2) = 4x is used to calculate the litter of piglets born on the farm; x represents the number of female pigs on the farm. Each female pig births 4 piglets. The farmer will need pens to house all the piglets. One pen can house 8. The number of pens required is written as p(x)=+1, where x is the number of piglets. The farmer always builds one extra pen. Which of the following functions represents the number of pens as a function of the female pigs? p(p(x)) p(l(z)) 1(p(x)) 1 (1 (x))

A group of students from the Czech Republic are going to visit Farhan's school. Farhan is asked to paint a Czech flag to put up in his classroom. The dimensions and colours of the flag are as shown: If one vertex of the triangle is exactly at the centre of the flag, how much area would Farhan paint blue?
