Rosa has 3 3/4 pounds of dough. She uses 1/8 of a pound for one roll. How many rolls could be made from Rosa's dough?

1 answer:

5 0

3 3/4 pounds so 3×3/4 = 2 1/4(mixed fraction)
2 1/4÷ 1/8= 2 1/4 × 8/1
for fraction division, yo
u keep the first fraction and flip the second fraction around. than you change the divide sign to multiply sign to find the answer

A salesman used three types of order forms: A, B, C. He used 40 of Form A. Of Form B he used four times as many as Form A plus 1

aivan3 [116]

Answer:

a. 440

Step-by-step explanation:

The information provided allows us to set up the following system of linear equations:

$A = 40\\B=4A+0.5C\\C=A+0.5B$

We already have the value for A, solving the system gives us the values for B and C:

$A = 40\\B=(4*40)+0.5C\\C=40+0.5B\\\\B -B-80 = (4*40)+0.5C-2C\\C=\frac{160+80}{1.5}\\C=160\\B= (4*40) +(0.5*160)\\B=240$

The total number of forms used is:

$A+B+C = 40+240+160 = 440$

He used 440 forms.

A rectangular prism has a length of 4.2 cm, a width of 5.8 cm, and a height of 9.6 cm. A similar prism has a length of 14.7 cm,

grigory [225]

Answer: 3.5

Step-by-step explanation:

Given: Dimensions of larger prism = length of 4.2 cm, a width of 5.8 cm, and a height of 9.6 cm.

Dimensions of smaller prism = length of 14.7 cm, a width of 20.3 cm, and a height of 33.6 cm.

Scale factor = $\dfrac{\text{Size of image}}{\text{Size of original figure}}$

Since, smaller figure is the original figure and the bigger one is the image.

So, scale factor = $\dfrac{14.7}{4.2}=3.5$ [Taking lengths

Hence, the factor to produce the corresponding dimensions of the larger prism = 3.5

Show how to make a ten to solve 13-7. Write the number sentence.

VARVARA [1.3K]

-7 + 3 + 10 = -4 + 10 = 10 - 4 = 6.

To turn 13 into 10, you need to break it up into 10 + 3, which does not change the value of 13. Then, you add 3 to -7, which results in -4. Next, you add -4 to 10 (or rather, subtract 4 from 10), which results in 6.

Why did the paper rip when the student tried to stretch out the horizontal axis of his graph? Unscramble this letters to figure

Fynjy0 [20]

Tension seems the obvious answer here, but then we are left with x. Since the horisontal line on a graph is 'x'. The answer appears to be Tension X (Tension on X axis. Hope this helps.
