Answer:
The answer is below
Step-by-step explanation:
The ratio of Keith's height and his nephew's height is 15:7. Let keith height be x cm and his nephews height be y cm.
Keiths height increased by 16% , therefore Keith new height is (100% + 16%) × x = 1.16x
The nephew height is doubled, therefore his new height is 2y.
Given that Keith is now 34 cm taller than his nephew
1.16x = 2y + 34
but x = (15/7)y
The nephews new height = 2y = 2(70) = 140 cm
Keith new height = 2y + 34 = 140 + 34 = 174 cm
Their total current height = 140 cm + 174 cm = 314 cm
We have been given that at north shire high school 87.5% of the teachers have a masters degree. Total number of teachers is 128.
Let us find how many teachers have a masters degree.
Therefore, 112 teachers have a masters degree.
Answer: 18.75 inches
Step-by-step explanation:
Let the height of the model be represented by x. Therefore, based on the information given in the question, we can form an equation which will be:
3/x = 32/200
Cross multiply
32 × x = 200 × 3
32x = 600
x = 600/32
x = 18.75
Therefore, the height of the model is 18.75 inches
