ABCD is a trapezoid. = 1 cm and = 5 cm, and the area = 7.5 cm2. What is the altitude of the trapezoid? 1.5 cm 2.5 cm 3 cm 2 cm

Ludmilka [50]

Answer:

2.5cm

Step-by-step explanation:

area of a trapeziod = 1/2 (a+b)×h

a=1cm

b=5cm

h=?

area= 7.5cm^2

••••• 7.5cm^2=1/2 (6)h

7.5= 3h

then height = 7.5/3= 2.5cm

How would i graph this equation y=3x+1

Kipish [7]

Answer:

(0,1)(1,4)

Step-by-step explanation:

Put in any value of x to find y, then you have a coordinate, then plot it

lets say i pick 0 for x

y = 3(0) + 1

y = 1

(0,1)

lets say i also pick 1 for x

y = 3(1)+1

y = 4

You need atleast two points to plot a line, these are two points.

The histogram below represents the high temperatures recorded each day over month period. Which of the following statements are

Kisachek [45]

Answer:

See possible solutions below.

Step-by-step explanation:

The statements are not given. But the following can be determined from the graph:

More days recorded temperatures between 82 and 84 then other temperatures.
The least number of days recorded temperatures between 88 and 90.
The histogram is skewed to the right also known as positive skewed distribution.
The mean and median will most likely be in the range of 82-84 temperatures. But the mean will be greater than the median.

A baker is using a cookie that calls for 2 1/4 cups of flour to yield 36 cookies, how much flour will the baker neeto to make 90

andre [41]

Answer:

$5 \frac{5}{8}$ cups

Step-by-step explanation:

Given: A baker is using a cookie that calls for 2 $\frac{1}{4}$ cups of flour to yield 36 cookies.

To find the number of flour will the baker need to make 90 cookies, we form a proportion.

Let's convert 2 $\frac{1}{4}$ to improper fraction.

$2\frac{1}{4} = \frac{(2*4) + 1}{4} = \frac{9}{4}$

Let "x" be the amount flour to make 90 cookies

<u>Amount of Flour</u> <u>Number of cookies</u>

$\frac{9}{4}$ 36

x 90

Now form a proportion.

$\frac{\frac{9}{4}}{x} = \frac{36}{90}$

Now let's cross multiply, we get

$\frac{9}{4} *90 = 36x\\\$

$\frac{810}{4} = 36x\\x = \frac{810 }{4*36} \\x = \frac{810}{144} \\\\x = 5 \frac{90}{144}$

Now let's simplify the fraction part, Here the GCF of 90 and 144 is 18, so dividing the fraction's numerator and the denominator by 18, we get

x = $5 \frac{5}{8}$ cups

So the baker needs $5 \frac{5}{8}$ cups to make 90 cookies.

In the diagram below of right triangle ACB, altitude CD is drawn by hypotenuse AB. if AB= 36 and AC= 12, what is the length of A

Nady [450]

36 squared + 12 squared = AD squared
1296 + 144 = AD squared
square root of 1440 = AD
37.95
