Standards basis

Common Core State Standards for Mathematics (CCSS-M) / New Hampshire mathematics standards — New Hampshire

How the NH SAS reports it

New Hampshire SAS is the state assessment system, but the official math reporting structure was not accessible from the state page in this session. In practice, New Hampshire’s math assessments are aligned to the state’s K-12 mathematics standards, which closely mirror Common Core grade-level domains and clusters.

Similar triangles MNOMNO and PQRPQR have areas 44 and 36.36\textsf{.} Side MNMN corresponds to side PQ,PQ\textsf{,} and MN=5.MN = 5\textsf{.} What is the length of PQ?PQ\textsf{?}

The area ratio is 364=9=k2,\dfrac{36}{4} = 9 = k^{2}\textsf{,} so k=3.k = 3\textsf{.} Then PQ=53=15.PQ = 5 \cdot 3 = 15\textsf{.}

A sports drink is made with syrup and water in a ratio of 55 to 2020. How many cups of syrup should be added to 11 gallon of water to make the drink in this ratio? (44 cups == 11 quart, 44 quarts == 11 gallon.)

One gallon of water is 1616 cups. With a 55 to 2020 ratio, 520=x16\dfrac{5}{20} = \dfrac{x}{16}, so 20x=8020x = 80 and x=4x = 4 cups of syrup.

A restaurant bill is $72\text{\char36}72. What is a 15%15\% tip, in dollars?

Tip =0.15×72=10.80= 0.15 \times 72 = 10.80 dollars.

A passenger train traveled 348348 miles in 44 hours at a constant speed. What was the train's speed, in miles per hour?

Speed = distance ÷\div time: 3484=87\dfrac{348}{4} = 87 miles per hour.

Given a:b=5:2a:b = 5:2 and a=75a = 75, find bb.

ab=52\dfrac{a}{b} = \dfrac{5}{2}. With a=75a = 75, 75b=52\dfrac{75}{b} = \dfrac{5}{2}, so 5b=1505b = 150 and b=30b = 30.

Find the simple interest on $400\text{\char36}400 at 25%25\% per year for 11 year.

I=400×0.25×1=$100I = 400 \times 0.25 \times 1 = \$100.

The table shows two juice mixtures. For Mixture A, what decimal part of the total liquid is concentrate?
MixtureConcentrate (L)Water (L)A28B39\begin{array}{l|c|c} \text{Mixture} & \text{Concentrate (L)} & \text{Water (L)} \\ \hline \text{A} & 2 & 8 \\ \text{B} & 3 & 9 \end{array}

Mixture A has 2+8=102+8=10 liters total. Concentrate is 210=0.2\dfrac{2}{10}=0.2 of the mixture.
