If the length of the shorter diagonal AC of rhombus ABCD is 7 and measure of angle ABC = 60. Find the measure of angle BAC
Answer:
120 degrees
Step-by-step explanation:
It has to equal to 360, and so since angle B is 60 degrees, and it's the smaller angle, A and C have to be 120 degrees, and D has to be 60 degrees. Hope this helps.
Angela baked cookies. She gave 1/3 of them to her sister, and she put 5/8 of the remaining cookies in the freezer. If she had 1 dozen cookies left, how many cookies did she bake?
Answer:
We find the fraction of a number by doing two steps: first, multiply the whole number by the numerator, and then divide the product we get by the denominator.
multiplying fraction by a number
Let's solve real-world problems about fractions of a number.
Word Problem Examples
cookies
Jane baked 24 chocolate chip cookies. She gave 1/3 of the cookies to her neighbor. How many cookies did she give to her neighbor?
What is the problem asking us to do?
That's right!
We need to figure out what 1/3 of 24 is.
1/3 of 24 is the same as this:
24 × 1/3 = ?
First, multiply 24 by the numerator:
24 × 1 = 24
Then, divide the product we got by the denominator:
24 ÷ 3 = 8
✅ Now we know that she gave 8 cookies to her neighbor.
Here are more questions about this problem:
Of the cookies that were left, Jane gave 3/4 to her parents, and she ate the rest. How many cookies did she give to her parents? How many cookies did she eat?
The problem tells us to figure out two things:
- the number of cookies that Jane gave to her parents,
- the number of cookies that Jane ate.
But first, we have to find out how many cookies were left, after Jane gave some away to her neighbor.
She started with 24 cookies and gave 8 cookies away.
Let's subtract:
24 - 8 = 16 cookies
So, Jane had 16 cookies left.
How many cookies did Jane's parents get if she gave them 3/4 of 16?
3/4 of 16 is the same as this:
16 × 3/4 = ?
First, multiply 16 by the numerator:
16 × 3 = 48
Then, divide the product we got by the denominator:
48 ÷ 4 = 12
✅ Jane gave 12 cookies to her parents.
Now, let's find out how many cookies Jane ate.
We know that Jane ate all the cookies that were left.
She had 16 cookies. Then, she gave 12 to her parents.
How many are left?
We need to subtract to figure this out:
16 - 12 = 4
✅ Jane ate 4 cookie
She baked 48 cookies in total as obtained by forming a numerical expression of the statement.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given that, Angela baked x cookies.
She gave 1/3 of them to her sister, and she put 5/8 of 5/8th of the remaining cookies in the freezer.
∴ x - (1/3)x - (2/3)×(5/8)x = 12.
x - (1/3)x - (5/12)x = 12.
(2/3)x - (5/12)x = 12.
(8x - 5x)/12 = 12.
3x = 144.
x = 48

douple check - 1.25 times4 is 5!
Answer:
1.25
Step-by-step explanation:
If we divide the amount it costs for 4 rolls (5), by the amount of rolls bought (4), we get 1.25, which is the correct!
Don't do 4 divided by 5, or you would be saying 5 rolls bought for 4 bucks!

A bakery produced two batches of bread with 80 loves in each batch. It sold 30 loves each hour. How many loves of bread were sold in 4 hours? How many loves of bread were left to sale
Answer:
-120 loves of bread were sold in 4 hours.
-40 loves of bread wereleft to sale.
Step-by-step explanation:
To determine the amount of loves of bead that were sold in 4 hours, you have to mutiply the amount of loves sold each hour for 4:
30*4=120
This means that 120 loves of bread were sold in 4 hours.
Now, to determine the amount of loves of bread left to sale, you have to find the amount of loves produced on the two batches of bread by multiplying the amount produce in each batch for 2:
80*2=160
Finally, you have to subtract the amount of loves sold in 4 hours from the amount produced in two batches:
160-120=40
According to this, 40 loves of bread were left to sale.

Write an equation of the line that passes through the given point and has the given slope. (1,-5); slope: - 2/3 SLOPE INTERCEPT FORM
Answer:
y = [tex]-\frac{2}{3}[/tex] x - [tex]-\frac{13}{3}[/tex]
Step-by-step explanation:
Given dimensions:
Slope = [tex]-\frac{2}{3}[/tex]
Coordinates = (1, -5)
Now;
Equation of the line through the given points;
Solution:
The equation of a line is given as;
y = mx + c
x and y are the coordinates
m is the slope
c is the intercept
So;
let us find the y-intercept;
-5 = [tex]-\frac{2}{3}[/tex] x 1 + C
c = -5 + [tex]\frac{2}{3}[/tex] = [tex]-\frac{13}{3}[/tex]
The equation of the line is ;
y = [tex]-\frac{2}{3}[/tex] x - [tex]-\frac{13}{3}[/tex]

Answer:
8. p(t) = 5(2^t)
9. 20, 40, 80
10. doubles every year
11. multiplies by 4
12. no, it will soon exceed available habitat
Step-by-step explanation:
8. From the graph, a = p(0) = 5, and b = p(1)/p(0) = 10/5 = 2.
The function is ...
p(t) = 5(2^t)
__
9. You can read the values from the graph: 2 years: 20; 3 years: 40; 4 years: 80.
If you insist on evaluating the function, you have ...
p(2) = 5(2^2) = 5·4 = 20
p(3) = 5(2^3) = 5·8 = 40
p(4) = 5(2^4) = 5·16 = 80
__
10. The population doubles each year.
__
11. In 2 years, the population doubles twice, so is multiplied by 4.
__
12. No. Exponential functions don't last long in the real world. Eventually, required resources run out. In 15 years, there would be 163,840 snakes; in 20 years, there would be 5.2 million snakes; in 40 years, there would be 5.5 trillion snakes, about 44 snakes for every acre of land on earth (including polar areas).
