How the Ohio State Tests reports it

Ohio's State Tests are Ohio-specific assessments built around Ohio's Learning Standards for Mathematics, which are CCSS-derived and retain the Common Core grade-level domains and (at high school) conceptual categories nearly verbatim. Math is tested in grades 3-8 and via end-of-course exams; the high-school graduation pathway uses Algebra I and Geometry, but students in an integrated sequence take Integrated Mathematics I and II in their place (these integrated courses are not given their own bands here — Integrated Math I draws on the same Algebra/Functions/Number & Quantity/Geometry/Statistics content as Algebra I plus early Geometry, and Integrated Math II adds the remaining Geometry/Functions/Probability content). The reporting categories below are the official math subscore categories Ohio publishes per test; because no public item-percentage blueprint was retrievable, the cluster-level Common Core domains those subscores cover are used (the standards' grade-level domains, which the reporting categories mirror).

Blueprint & weighting

Ohio publishes per-test math subscore (reporting) categories in its Subscore Definitions chart and raw-score subscale ranges, but no public per-category item-percentage blueprint was retrievable; the statistical summaries report the number of items per subscore by administration rather than a fixed blueprint weighting.

Two similar triangles have perimeters in the ratio 3:53 : 5. The shortest side of the smaller triangle is 66. What is the length of the shortest side of the larger triangle if corresponding sides are compared?

Similar figures have a constant scale factor between corresponding lengths. Perimeter ratio 3:53 : 5 means each side of the larger triangle is 53\dfrac{5}{3} times the matching side of the smaller. The larger shortest side is 653=106 \cdot \dfrac{5}{3} = 10.

In a right triangle, sinα=513\sin\alpha = \dfrac{5}{13} and tanα=512\tan\alpha = \dfrac{5}{12}. What is cosα\cos\alpha?

cosα=sinαtanα=513512=513125=1213\cos\alpha = \dfrac{\sin\alpha}{\tan\alpha} = \dfrac{\dfrac{5}{13}}{\dfrac{5}{12}} = \dfrac{5}{13} \cdot \dfrac{12}{5} = \dfrac{12}{13}, or from the 55-1212-1313 triangle: adjacent 1212, hypotenuse 1313.

A parking meter that is 55 feet tall casts a shadow 22 feet long. A radio antenna casts a shadow at the same time. If the antenna is 3535 feet tall, how long is its shadow, in feet?

Use 52=35s\dfrac{5}{2} = \dfrac{35}{s}. Cross-multiply: 5s=705s = 70, so s=14s = 14 feet.

In a 4545-4545-9090 triangle one leg is 1212. What is the other leg?

Both legs of a 4545-4545-9090 triangle are equal, so the other leg is 1212.

A concrete drainage pipe is a hollow right circular cylinder. The outer radius is r1=6r_1 = 6 meters, the inner radius is r2=4r_2 = 4 meters, and the pipe is 55 meters long. What is the volume of concrete in the pipe wall, in cubic meters?

Wall volume is outer minus inner: V=πh(r12r22)=π(5)(6242)=π(5)(20)=100πV = \pi h(r_1^{2} - r_2^{2}) = \pi (5)(6^{2} - 4^{2}) = \pi (5)(20) = 100\pi cubic meters.
